Use of injectable drugs in newborns represents more than 90% of prescriptions and requires special precautions in order to ensure more safety and efficiency. The aim of this study is to gather errors relating to the administration of injectable drugs and to suggest corrective actions. This descriptive and transversal study has evaluated 300 injectable drug administrations in a neonatology unit. Two hundred and sixty-one administrations have contained an error. Data are collected by direct observations of administrative act. Errors observed are: an inappropriate mixture (2.6% of cases); an incorrect delivery rate (33.7% of cases); incorrect dilutions (26.7% of cases); error in calculation of the dose to be injected (16.7% of cases); error while sampling small volumes (6.3% of cases); error or omission of administration schedule (1% of cases). These data have enabled us to evaluate administration of injectable drugs in neonatology. Different types of errors observed could be a source of therapeutic inefficiency, extended lengths of stay or iatrogenic drug. Following these observations, corrective actions have been undertaken by pharmacists and consist of: organizing training sessions for nursing; developing an explanatory guide for dilution and administration of injectable medicines, which was made available to the clinical service. Collaborative strategies doctor-nurse-pharmacist can help to reduce errors in the medication process especially during his administration. It permits improvement of injectable drugs use, offering more security and better efficiency and contribute to guarantee ideal therapy for patients. Copyright © 2015.

The prescription drugs regulated in the most restrictive controlled substance schedule for those with an approved therapeutic use vary widely in their real world risk of abuse and harm. Opioid analgesics have the highest rates of abuse, overdose death, drug abuse treatment needs and societal costs in comparison to other Schedule II drugs. Stimulants for attention-deficit/hyperactivity disorders (ADHD) account for substantially lower rates of abuse, harm, and public health impact. The scheduling of drugs is determined by the World Health Organization, the United States Food and Drug Administration, and other regulatory agencies, through a quasi-public process that relies heavily on pre-marketing studies that are conducted in highly controlled clinical settings. We propose that it is increasingly in the interest of science-based regulation and public health to recognize and communicate differences among drugs based on their real-world abuse and public health harm using surveillance data. Appropriate differentiation through labeling of drugs that will likely remain in the same schedule could provide powerful incentives for drug development and research, would aid prescriber/patient decision making by informing them of real differences across drugs within a schedule, and may also contribute to public health efforts to reduce drug abuse. There are risks of course, that include inadvertent perceptions that drugs labeled to be lower in risk are not taken as seriously as others in the same category. Challenges such as these, however, can be overcome and should not serve as barriers to objective communications regarding a drug's actual risks. Copyright © 2011 Elsevier Ireland Ltd.

The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic opioids, N-(2-fluorophenyl)-N-(1-phenethylpiperidin-4-yl)propionamide (ortho-fluorofentanyl or 2-fluorofentanyl), N-(1-phenethylpiperidin-4-yl)-N-phenyltetrahydrofuran-2-carboxamide (tetrahydrofuranyl fentanyl), and 2-methoxy-N-(1-phenethylpiperidin-4-yl)-N-phenylacetamide (methoxyacetyl fentanyl), into Schedule I. This action is based on a finding by the Administrator that the placement of ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl into Schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to Schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl.

Cancer therapy using chemotherapeutic drugs frequently involves injection of the drug into the body through some intravenous mode of administration, viz, continuous (drip) infusion or single/multiple bolus injection(s). An understanding of the effect of the various modes of administration upon tumor penetration of drug is essential to rational design of drug therapy. This paper investigates drug penetration into a model tumor of slab geometry (between two capillaries) in which the overall transport rate of drug is limited by intra-tumor transport characterized by an effective diffusion coefficient. Employing the method of Finite Fourier Transforms (FFT), analytical solutions have been obtained for transient drug distribution in both the plasma and the tumor following three modes of administration, viz, continuous infusion, single bolus injection and equally-spaced equal-dose multiple bolus injections, of a given amount of drug. The qualitative trends exhibited by the plasma drug distribution profiles are consistent with reported experimental studies. Two concepts, viz, the dimensionless decay constant and the plasma/tumor drug concentration trajectories, are found to be particularly useful in the rational design of drug therapy. The dimensionless decay constant provides a measure of the rate of drug decay in the plasma relative to the rate of drug diffusion into the tumor and is thus characteristic of the tumor/drug system. The magnitude of this parameter dictates the choice of drug administration mode for minimizing drug decay in the plasma while simultaneously maximizing drug transport into the tumor. The concentration trajectories provide a measure of the plasma drug concentration relative to the tumor drug concentration at various times following injection. When the tumor drug concentration exceeds the plasma drug concentration, the drug will begin to diffuse out of the tumor. Knowledge of the time at which this diffusion reversal occurs is especially useful

Chk1 inhibitors have emerged as promising anticancer therapeutic agents particularly when combined with antimetabolites such as gemcitabine, cytarabine or hydroxyurea. Here, we address the importance of appropriate drug scheduling when gemcitabine is combined with the Chk1 inhibitor MK-8776, and the mechanisms involved in the schedule dependence. Growth inhibition induced by gemcitabine plus MK-8776 was assessed across multiple cancer cell lines. Experiments used clinically relevant “bolus” administration of both drugs rather than continuous drug exposures. We assessed the effect of different treatment schedules on cell cycle perturbation and tumor cell growth in vitro and in xenograft tumor models. MK-8776 induced an average 7-fold sensitization to gemcitabine in 16 cancer cell lines. The time of MK-8776 administration significantly affected the response of tumor cells to gemcitabine. Although gemcitabine induced rapid cell cycle arrest, the stalled replication forks were not initially dependent on Chk1 for stability. By 18 h, RAD51 was loaded onto DNA indicative of homologous recombination. Inhibition of Chk1 at 18 h rapidly dissociated RAD51 leading to the collapse of replication forks and cell death. Addition of MK-8776 from 18–24 h after a 6-h incubation with gemcitabine induced much greater sensitization than if the two drugs were incubated concurrently for 6 h. The ability of this short incubation with MK-8776 to sensitize cells is critical because of the short half-life of MK-8776 in patients’ plasma. Cell cycle perturbation was also assessed in human pancreas tumor xenografts in mice. There was a dramatic accumulation of cells in S/G 2 phase 18 h after gemcitabine administration, but cells had started to recover by 42 h. Administration of MK-8776 18 h after gemcitabine caused significantly delayed tumor growth compared to either drug alone, or when the two drugs were administered with only a 30 min interval. There are two reasons why delayed

Rhesus monkeys were trained to complete three multiple schedules. The schedules consisted of three components: a fixed interval (component 1), a variable interval (component 2), and a fixed ratio (component 3). During components 1 and 2, pressing lever 1 was always reinforced by food delivery. During component 3, pressing lever 2 resulted in either food delivery or intravenous infusions of saline solution, solutions of cocaine, of d-amphetamine, of phenmetrazine, or fenetylline. In schedule I, animals were presented with all three components independent of key-pressing behavior during components 1 and 2. In schedule II the availability of component 2 was dependent on completion of component 1. Component 3 was made available only on completion of component 2. Noncompletion of components 1 or 2 resulted in time-out of 15 and 10 min, respectively. Schedule III was identical with schedule II, except that in schedule III the completion of components was indicated only by a change in the lever lights. The influence of self-administered drugs on behavior in all three components was evaluated. Self-administration of psychomotor stimulants impaired the performance of animals and delayed completion of components 1 and 2 of schedules I, II, and III. The effects on behavior were similar with low drug intake in schedule III, moderate intake in schedule II, and high drug intake in schedule I. These effects were strong with self-administration of phenmetrazine, moderate with self-administration of cocaine and d-amphetamine, and weak with self-administration of fenetylline.

[New drug development by innovative drug administration--"change" in pharmaceutical field].
Nagai, T
1997-11-01
New drug development can be made by providing products of higher "selectivity for the drug" for medical treatment. There are two ways for the approach to get higher "selectivity of drug": 1) discovery of new compounds with high selectivity of drug; 2) innovation of new drug administration, that is new formulation and/or method with high selectivity of drug by integration and harmonization of various hard/soft technologies. An extensive increase of biological information and advancement of surrounding science and technology may modify the situation as the latter overcomes the former in the 21 century. As the science and technology in the 21 century is said to be formed on "3H", that is, 1. hybrid; 2. hi-quality; 3. husbandry, the new drug development by innovative drug administration is exactly based on the science and technology of 3H. Its characteristic points are interdisciplinary/interfusion, international, of philosophy/ethics, and systems of hard/hard/heart. From these points of view, not only the advance of unit technology but also a revolution in thinking way should be "must" subjects. To organize this type of research well, a total research activity such as ROR (research on research) might take an important and efficient role. Here the key words are the "Optimization technology" and "Change in Pharmaceutical Fields." As some examples of new drug innovation, our trials on several topical mucosal adhesive dosage forms and parenteral administration of peptide drugs such as insulin and erythropoietin will be described.

2012-03-01
Full Text Available Abstract Background Medication errors can occur at any of the three steps of the medication use process: prescribing, dispensing and administration. We aimed to determine the incidence, type and clinical importance of drug administration errors and to identify risk factors. Methods Prospective study based on disguised observation technique in four wards in a teaching hospital in Paris, France (800 beds. A pharmacist accompanied nurses and witnessed the preparation and administration of drugs to all patients during the three drug rounds on each of six days per ward. Main outcomes were number, type and clinical importance of errors and associated risk factors. Drug administration error rate was calculated with and without wrong time errors. Relationship between the occurrence of errors and potential risk factors were investigated using logistic regression models with random effects. Results Twenty-eight nurses caring for 108 patients were observed. Among 1501 opportunities for error, 415 administrations (430 errors with one or more errors were detected (27.6%. There were 312 wrong time errors, ten simultaneously with another type of error, resulting in an error rate without wrong time error of 7.5% (113/1501. The most frequently administered drugs were the cardiovascular drugs (425/1501, 28.3%. The highest risks of error in a drug administration were for dermatological drugs. No potentially life-threatening errors were witnessed and 6% of errors were classified as having a serious or significant impact on patients (mainly omission. In multivariate analysis, the occurrence of errors was associated with drug administration route, drug classification (ATC and the number of patient under the nurse's care. Conclusion Medication administration errors are frequent. The identification of its determinants helps to undertake designed interventions.

Congestion game scheduling for virtual drug screening optimization
Nikitina, Natalia; Ivashko, Evgeny; Tchernykh, Andrei
2018-02-01
In virtual drug screening, the chemical diversity of hits is an important factor, along with their predicted activity. Moreover, interim results are of interest for directing the further research, and their diversity is also desirable. In this paper, we consider a problem of obtaining a diverse set of virtual screening hits in a short time. To this end, we propose a mathematical model of task scheduling for virtual drug screening in high-performance computational systems as a congestion game between computational nodes to find the equilibrium solutions for best balancing the number of interim hits with their chemical diversity. The model considers the heterogeneous environment with workload uncertainty, processing time uncertainty, and limited knowledge about the input dataset structure. We perform computational experiments and evaluate the performance of the developed approach considering organic molecules database GDB-9. The used set of molecules is rich enough to demonstrate the feasibility and practicability of proposed solutions. We compare the algorithm with two known heuristics used in practice and observe that game-based scheduling outperforms them by the hit discovery rate and chemical diversity at earlier steps. Based on these results, we use a social utility metric for assessing the efficiency of our equilibrium solutions and show that they reach greatest values.

To compare CAWCS pharmacy-dispensed (PD) drug prices under alternative fee schedules, and identify combinations of alternative benchmarks that have prices available for the largest percentage of PD drugs and that best reach budget neutrality. Claims transaction-level data (2011-2013) from CAWCS were used to estimate total annual PD pharmaceutical payments. Medi-Cal pricing data was from the Workman's Compensation Insurance System (WCIS). Average Wholesale Prices (AWP), Wholesale Acquisition Costs (WAC), Direct Prices (DP), Federal Upper Limit (FUL) prices, and National Average Drug Acquisition Costs (NADAC) were from Medi-Span. We matched National Drug Codes (NDCs), pricing dates, and drug quantity for comparisons. We report pharmacy-dispensed (PD) claims frequency, reimbursement matching rate, and paid costs by CAWCS as the reference price against all alternative price benchmarks. Of 12,529,977 CAWCS claims for pharmaceutical products 11.6% (1,462,814) were for PD drugs. Prescription drug cost for CAWCS was over $152M; $63.9M, $47.9M, and $40.6M in 2011-2013. Ninety seven percent of these CAWCS PD claims had a Medi-Cal price. Alternative mechanisms provided a price for fewer claims; NADAC 94.23%, AWP 90.94%, FUL 73.11%, WAC 66.98%, and DP 14.33%. Among CAWCS drugs with no Medi-Cal price in PD claims, AWP, WAC, NADAC, DP, and FUL provided prices for 96.7%, 63.14%, 24.82%, 20.83%, and 15.08% of claims. Overall CAWCS paid 100.52% of Medi-Cal, 60% of AWP, 97% of WAC, 309.53% of FUL, 103.83% of DP, and 136.27% of NADAC. CAWCS current Medi-Cal fee-schedule price list for PD drugs is more complete than all alternative fee-schedules. However, all reimbursement approaches would require combinations of pricing benchmarks

Optimal Intermittent Dose Schedules for Chemotherapy Using Genetic Algorithm
Directory of Open Access Journals (Sweden)
Nadia ALAM
2013-08-01
Full Text Available In this paper, a design method for optimal cancer chemotherapy schedules via genetic algorithm (GA is presented. The design targets the key objective of chemotherapy to minimize the size of cancer tumor after a predefined time with keeping toxic side effects in limit. This is a difficult target to achieve using conventional clinical methods due to poor therapeutic indices of existing anti-cancer drugs. Moreover, there are clinical limitations in treatment administration to maintain continuous treatment. Besides, carefully decided rest periods are recommended to for patient’s comfort. Three intermittent drug scheduling schemes are presented in this paper where GA is used to optimize the dose quantities and timings by satisfying several treatment constraints. All three schemes are found to be effective in total elimination of cancer tumor after an agreed treatment length. The number of cancer cells is found zero at the end of the treatment for all three cases with tolerable toxicity. Finally, two of the schemes, “Fixed interval variable dose (FIVD and “Periodic dose” that are periodic in characteristic have been emphasized due to their additional simplicity in administration along with friendliness to patients. responses to the designed treatment schedules. Therefore the proposed design method is capable of planning effective, simple, patient friendly and acceptable chemotherapy schedules.

Rectal drug administration: clinical pharmacokinetic considerations.
de Boer, A G; Moolenaar, F; de Leede, L G; Breimer, D D
1982-01-01
The human rectum represents a body cavity in which drugs can be easily introduced and retained and from which absorption is well possible. There are important therapeutic reasons why it is sometimes preferable to give a drug rectally rather than orally, e.g. in cases of nausea and vomiting. Drawbacks of rectal drug administration include the interruption of absorption by defaecation and lack of patient acceptability. The mechanism of drug absorption from the rectum is probably no different to that in the upper part of the gastrointestinal tract, despite the fact that the physiological circumstances (e.g. pH, fluid content) differ substantially, Absorption from aqueous and alcoholic solutions may occur very rapidly, which has proved to be of considerable therapeutic value in the rapid suppression of acute convulsive attacks by diazepam (e.g. in children), but absorption from suppositories is generally slower and very much dependent on the nature of the suppository base, the use of surfactants or other additives, particle size of the active ingredient, etc. There is some evidence that hepatic first-pass elimination of high clearance drugs is partially avoided after rectal administration, e.g. lignocaine. This can be explained by the rectal venous blood supply: the upper part is connected with the portal system, whereas the lower part is directly connected with the systemic circulation. Plasma concentration data following rectal administration of representatives of several classes of drugs are reviewed: anticonvulsants, non-narcotic analgesics and non-steroidal anti-inflammatory agents, hypnosedatives and anaesthetics, strong analgesics, theophylline and derivatives, corticosteroids, antibacterial agents, thiazinamium, promethazine, hyoscine-N-butyl-bromide, streptokinase, progesterone, ergotamine tartrate and levodopa. Only limited number of cases has it been adequately shown that the rectal route of administration gives plasma concentrations which are comparable to

[Innovative therapeutic strategies for intravesical drug administration].
Moch, C; Salmon, D; Rome, P; Marginean, R; Pivot, C; Colombel, M; Pirot, F
2013-05-01
Perspectives for innovative pharmaceutical molecules and intravesical administration of pharmacological agents are presented in the present review carried out from a recent literature. This review of the literature was built by using the PubMed and ScienceDirect databases running 20keywords revealing 34publications between 1983 and 2012. The number of referenced articles on ScienceDirect has increased in recent years, highlighting the interest of scientists for intravesical drug administration and the relevance of innovating drug delivery systems. Different modalities of intravesical administration using physical (e.g., iontophoresis, electroporation) or chemical techniques (e.g., enzyme, solvent, nanoparticles, liposomes, hydrogels) based on novel formulation methods are reported. Finally, the development of biopharmaceuticals (e.g., bacillus Calmette-Guérin, interferon α) and gene therapies is also presented and analyzed in this review. The present review exhibits new development in the pipeline for emerging intravesical drug administration strategies. Knowledge of all these therapies allows practitioners to propose a specific and tailored treatment to each patient with limiting systemic side effects. Copyright © 2013 Elsevier Masson SAS.

Drug scheduling of cancer chemotherapy based on natural actor-critic approach.
Ahn, Inkyung; Park, Jooyoung
2011-11-01
Recently, reinforcement learning methods have drawn significant interests in the area of artificial intelligence, and have been successfully applied to various decision-making problems. In this paper, we study the applicability of the NAC (natural actor-critic) approach, a state-of-the-art reinforcement learning method, to the drug scheduling of cancer chemotherapy for an ODE (ordinary differential equation)-based tumor growth model. ODE-based cancer dynamics modeling is an active research area, and many different mathematical models have been proposed. Among these, we use the model proposed by de Pillis and Radunskaya (2003), which considers the growth of tumor cells and their interaction with normal cells and immune cells. The NAC approach is applied to this ODE model with the goal of minimizing the tumor cell population and the drug amount while maintaining the adequate population levels of normal cells and immune cells. In the framework of the NAC approach, the drug dose is regarded as the control input, and the reward signal is defined as a function of the control input and the cell populations of tumor cells, normal cells, and immune cells. According to the control policy found by the NAC approach, effective drug scheduling in cancer chemotherapy for the considered scenarios has turned out to be close to the strategy of continuing drug injection from the beginning until an appropriate time. Also, simulation results showed that the NAC approach can yield better performance than conventional pulsed chemotherapy. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

Peer influences on drug self-administration: an econometric analysis in socially housed rats.
Peitz, Geoffrey W; Strickland, Justin C; Pitts, Elizabeth G; Foley, Mark; Tonidandel, Scott; Smith, Mark A
2013-04-01
Social-learning theories of substance use propose that members of peer groups influence the drug use of other members by selectively modeling, reinforcing, and punishing either abstinence-related or drug-related behaviors. The objective of the present study was to examine the social influences on cocaine self-administration in isolated and socially housed rats, under conditions where the socially housed rats were tested simultaneously with their partner in the same chamber. To this end, male rats were obtained at weaning and housed in isolated or pair-housed conditions for 6 weeks. Rats were then implanted with intravenous catheters and cocaine self-administration was examined in custom-built operant conditioning chambers that allowed two rats to be tested simultaneously. For some socially housed subjects, both rats had simultaneous access to cocaine; for others, only one rat of the pair had access to cocaine. An econometric analysis was applied to the data, and the reinforcing strength of cocaine was measured by examining consumption (i.e. quantity demanded) and elasticity of demand as a function of price, which was manipulated by varying the dose and ratio requirements on a fixed ratio schedule of reinforcement. Cocaine consumption decreased as a function of price in all groups. Elasticity of demand did not vary across groups, but consumption was significantly lower in socially housed rats paired with a rat without access to cocaine. These data suggest that the presence of an abstaining peer decreases the reinforcing strength of cocaine, thus supporting the development of social interventions in drug abuse prevention and treatment programs.

Food and Drug Administration Drug Approval Process: A History and Overview.
Williams, Christopher Ty
2016-03-01
In this article, the processing of investigational and new drug applications is described and the standard and expedited review processes are examined. The efforts of the US Food and Drug Administration to ensure greater agency transparency and fiscal responsibility and intensify oversight during the drug development and approval process are reviewed. Often attributed to a decrease in the number of uninsured adults, both the increase in prescription drug sales and the high costs associated with bringing a new drug to market highlight the necessity for a streamlined and cost-effective process to deliver these drugs safely and effectively.

Discrete-choice modelling of patient preferences for modes of drug administration.
Tetteh, Ebenezer Kwabena; Morris, Steve; Titcheneker-Hooker, Nigel
2017-12-01
The administration of (biologically-derived) drugs for various disease conditions involves consumption of resources that constitutes a direct monetary cost to healthcare payers and providers. An often ignored cost relates to a mismatch between patients' preferences and the mode of drug administration. The "intangible" benefits of giving patients what they want in terms of the mode of drug delivery is seldom considered. This study aims to evaluate, in monetary terms, end-user preferences for the non-monetary attributes of different modes of drug administration using a discrete-choice experiment. It provides empirical support to the notion that there are significant benefits from developing patient-friendly approaches to drug delivery. The gross benefits per patient per unit administration is in the same order of magnitude as the savings in resource costs of administering drugs. The study argues that, as long as the underlying manufacturing science is capable, a patient-centred approach to producing drug delivery systems should be encouraged and pursued.

Full Text Available Metronomic chemotherapy using cyclophosphamide (CPA is widely associated with antiangiogenesis; however, recent studies implicate other immune-based mechanisms, including antitumor innate immunity, which can induce major tumor regression in implanted brain tumor models. This study demonstrates the critical importance of drug schedule: CPA induced a potent antitumor innate immune response and tumor regression when administered intermittently on a 6-day repeating metronomic schedule but not with the same total exposure to activated CPA administered on an every 3-day schedule or using a daily oral regimen that serves as the basis for many clinical trials of metronomic chemotherapy. Notably, the more frequent metronomic CPA schedules abrogated the antitumor innate immune and therapeutic responses. Further, the innate immune response and antitumor activity both displayed an unusually steep dose-response curve and were not accompanied by antiangiogenesis. The strong recruitment of innate immune cells by the 6-day repeating CPA schedule was not sustained, and tumor regression was abolished, by a moderate (25% reduction in CPA dose. Moreover, an ~20% increase in CPA dose eliminated the partial tumor regression and weak innate immune cell recruitment seen in a subset of the every 6-day treated tumors. Thus, metronomic drug treatment must be at a sufficiently high dose but also sufficiently well spaced in time to induce strong sustained antitumor immune cell recruitment. Many current clinical metronomic chemotherapeutic protocols employ oral daily low-dose schedules that do not meet these requirements, suggesting that they may benefit from optimization designed to maximize antitumor immune responses.

The Food and Drug Administration (FDA) is delaying until October 1, 2001, the effective date and reopening the administrative record to receive additional comments regarding certain requirements of a final rule published in the Federal Register of December 3, 1999 (64 FR 67720). The other provisions of the final rule become effective on December 4, 2000. The final rule implements the Prescription Drug Marketing Act of 1987 (PDMA), as modified by the Prescription Drug Amendments of 1992 (PDA) and the FDA Modernization Act of 1997 (the Modernization Act). FDA is delaying the effective date for certain requirements relating to wholesale distribution of prescription drugs by distributors that are not authorized distributors of record. FDA is also delaying the effective date of another requirement that would prohibit blood centers functioning as "health care entities" to act as wholesale distributors of blood derivatives. The agency is taking this action to address numerous concerns about the provisions raised by affected parties.

Data on drug administration are entered manually into anesthesia information management systems (AIMS). This study examined whether these data are accurate regarding drug name, dose administered, and time of administration, and whether the stage of anesthesia influences data accuracy. Real-time observational data on drug administration during elective operations were compared with computerized information on drug administration entered by anesthesiologists. A trained observer (K.D.) performed the observations. Data were collected during 57 operations which included 596 separate occasions of drug administration by 22 anesthesiologists. No AIMS records were found for 90 (15.1%) occasions of drug administration (omissions), while there were 11 (1.8%) AIMS records where drug administration was not observed. The AIMS and observer data matched for drug name on 495 of 596 (83.1%) occasions, for dose on 439 of 495 (92.5%) occasions, and for time on 476 of 495 (96.2%) occasions. Amongst the 90 omitted records, 34 (37.8%) were for vasoactive drugs with 24 (27.7%) for small doses of hypnotics. Omissions occurred mostly during maintenance: 50 of 153 (24.6%), followed by induction: 30 of 325 (9.2%) and emergence: 10 of 57 (17.5%) (P < 0.001). Time and dose inaccuracies occurred mainly during induction, followed by maintenance and emergence; time inaccuracies were 7/325 (8.3%), 10/203 (4.9%), and 0/57 (0%), respectively (P = 0.07), and dose inaccuracies were 15/325 (4.6%), 3/203 (1.5%), and 1/57 (1.7%), respectively (P = 0.11). The range of accuracy varies when anesthesiologists manually enter drug administration data into an AIMS. Charting omissions represent the largest cause of inaccuracy, principally by omissions of records for vasopressors and small doses of hypnotic drugs. Manually entered drug administration data are not without errors. Accuracy of entering drug administration data remains the responsibility of the anesthesiologist.

Hierarchical pulmonary target nanoparticles via inhaled administration for anticancer drug delivery.
Chen, Rui; Xu, Liu; Fan, Qin; Li, Man; Wang, Jingjing; Wu, Li; Li, Weidong; Duan, Jinao; Chen, Zhipeng

Inhalation administration, compared with intravenous administration, significantly enhances chemotherapeutic drug exposure to the lung tissue and may increase the therapeutic effect for pulmonary anticancer. However, further identification of cancer cells after lung deposition of inhaled drugs is necessary to avoid side effects on normal lung tissue and to maximize drug efficacy. Moreover, as the action site of the major drug was intracellular organelles, drug target to the specific organelle is the final key for accurate drug delivery. Here, we designed a novel multifunctional nanoparticles (MNPs) for pulmonary antitumor and the material was well-designed for hierarchical target involved lung tissue target, cancer cell target, and mitochondrial target. The biodistribution in vivo determined by UHPLC-MS/MS method was employed to verify the drug concentration overwhelmingly increasing in lung tissue through inhaled administration compared with intravenous administration. Cellular uptake assay using A549 cells proved the efficient receptor-mediated cell endocytosis. Confocal laser scanning microscopy observation showed the location of MNPs in cells was mitochondria. All results confirmed the intelligent material can progressively play hierarchical target functions, which could induce more cell apoptosis related to mitochondrial damage. It provides a smart and efficient nanocarrier platform for hierarchical targeting of pulmonary anticancer drug. So far, this kind of material for pulmonary mitochondrial-target has not been seen in other reports.

Systematic review of drug administration costs and implications for biopharmaceutical manufacturing.
Tetteh, Ebenezer; Morris, Stephen
2013-10-01
The acquisition costs of biologic drugs are often considered to be relatively high compared with those of nonbiologics. However, the total costs of delivering these drugs also depend on the cost of administration. Ignoring drug administration costs may distort resource allocation decisions because these affect cost effectiveness. The objectives of this systematic review were to develop a framework of drug administration costs that considers both the costs of physical administration and the associated proximal costs; and, as a case example, to use this framework to evaluate administration costs for biologics within the UK National Health Service (NHS). We reviewed literature that reported estimates of administration costs for biologics within the UK NHS to identify how these costs were quantified and to examine how differences in dosage forms and regimens influenced administration costs. The literature reviewed were identified by searching the Centre for Review and Dissemination Databases (DARE, NHS EED and HTA); EMBASE (The Excerpta Medica Database); MEDLINE (using the OVID interface); Econlit (EBSCO); Tufts Medical Center Cost Effectiveness Analysis (CEA) Registry; and Google Scholar. We identified 4,344 potentially relevant studies, of which 43 studies were selected for this systematic review. We extracted estimates of the administration costs of biologics from these studies. We found evidence of variation in the way that administration costs were measured, and that this affected the magnitude of costs reported, which could then influence cost effectiveness. Our findings suggested that manufacturers of biologic medicines should pay attention to formulation issues and their impact on administration costs, because these affect the total costs of healthcare delivery and cost effectiveness.

Common errors of drug administration in infants: causes and avoidance.
Anderson, B J; Ellis, J F
1999-01-01
Drug administration errors are common in infants. Although the infant population has a high exposure to drugs, there are few data concerning pharmacokinetics or pharmacodynamics, or the influence of paediatric diseases on these processes. Children remain therapeutic orphans. Formulations are often suitable only for adults; in addition, the lack of maturation of drug elimination processes, alteration of body composition and influence of size render the calculation of drug doses complex in infants. The commonest drug administration error in infants is one of dose, and the commonest hospital site for this error is the intensive care unit. Drug errors are a consequence of system error, and preventive strategies are possible through system analysis. The goal of a zero drug error rate should be aggressively sought, with systems in place that aim to eliminate the effects of inevitable human error. This involves review of the entire system from drug manufacture to drug administration. The nuclear industry, telecommunications and air traffic control services all practise error reduction policies with zero error as a clear goal, not by finding fault in the individual, but by identifying faults in the system and building into that system mechanisms for picking up faults before they occur. Such policies could be adapted to medicine using interventions both specific (the production of formulations which are for children only and clearly labelled, regular audit by pharmacists, legible prescriptions, standardised dose tables) and general (paediatric drug trials, education programmes, nonpunitive error reporting) to reduce the number of errors made in giving medication to infants.

Purpose: Permanent prostate brachytherapy spacers can be used to deliver sustained doses of radiosentitizing drug directly to the target, in order to enhance the radiation effect. Implantable nanoplatforms for chemo-radiation therapy (INCeRTs) have a maximum drug capacity and can be engineered to control the drug release schedule. The optimal schedule for sensitization during continuous low dose rate irradiation is unknown. This work studies the optimal release schedule of drug for both traditional sensitizers, and those that work by suppressing DNA repair processes. Methods: Six brachytherapy treatment plans were used to model the anatomy, implant geometry and calculate the spatial distribution of radiation dose and drug concentrations for a range of drug diffusion parameters. Three state partial differential equations (cells healthy, damaged or dead) modeled the effect of continuous radiation (radiosensitivities α,β) and cellular repair (time tr) on a cell population. Radiosensitization was modeled as concentration dependent change in α,β or tr which with variable duration under the constraint of fixed total drug release. Average cell kill was used to measure effectiveness. Sensitization by means of both enhanced damage and reduced repair were studied. Results: Optimal release duration is dependent on the concentration of radiosensitizer compared to the saturation concentration (csat) above which additional sensitization does not occur. Long duration drug release when enhancing α or β maximizes cell death when drug concentrations are generally over csat. Short term release is optimal for concentrations below saturation. Sensitization by suppressing repair has a similar though less distinct trend that is more affected by the radiation dose distribution. Conclusion: Models of sustained local radiosensitization show potential to increase the effectiveness of radiation in permanent prostate brachytherapy. INCeRTs with high drug capacity produce the greatest

Adverse Drug Events caused by Serious Medication Administration Errors
Sawarkar, Abhivyakti; Keohane, Carol A.; Maviglia, Saverio; Gandhi, Tejal K; Poon, Eric G
2013-01-01
OBJECTIVE To determine how often serious or life-threatening medication administration errors with the potential to cause patient harm (or potential adverse drug events) result in actual patient harm (or adverse drug events (ADEs)) in the hospital setting. DESIGN Retrospective chart review of clinical events that transpired following observed medication administration errors. BACKGROUND Medication errors are common at the medication administration stage for hospitalized patients. While many of these errors are considered capable of causing patient harm, it is not clear how often patients are actually harmed by these errors. METHODS In a previous study where 14,041 medication administrations in an acute-care hospital were directly observed, investigators discovered 1271 medication administration errors, of which 133 had the potential to cause serious or life-threatening harm to patients and were considered serious or life-threatening potential ADEs. In the current study, clinical reviewers conducted detailed chart reviews of cases where a serious or life-threatening potential ADE occurred to determine if an actual ADE developed following the potential ADE. Reviewers further assessed the severity of the ADE and attribution to the administration error. RESULTS Ten (7.5% [95% C.I. 6.98, 8.01]) actual adverse drug events or ADEs resulted from the 133 serious and life-threatening potential ADEs, of which 6 resulted in significant, three in serious, and one life threatening injury. Therefore 4 (3% [95% C.I. 2.12, 3.6]) serious and life threatening potential ADEs led to serious or life threatening ADEs. Half of the ten actual ADEs were caused by dosage or monitoring errors for anti-hypertensives. The life threatening ADE was caused by an error that was both a transcription and a timing error. CONCLUSION Potential ADEs at the medication administration stage can cause serious patient harm. Given previous estimates of serious or life-threatening potential ADE of 1.33 per 100

Drug treatment may be related to the development of adverse drug reactions (ADRs). In this paper, we evaluated the ADRs in patients admitted to Catanzaro Hospital. After we obtained the approval by local Ethical Committee, we performed a retrospective study on clinical records from March 01, 2013 to April 30, 2015. The association between drug and ADR or between drug and drug-drug-interactions (DDIs) was evaluated using the Naranjo's probability scale and Drug Interaction Probability Scale (DIPS), respectively. During the study period, we analyzed 2870 clinical records containing a total of 11,138 prescriptions, and we documented the development of 770 ADRs. The time of hospitalization was significantly higher (P<0.05) in women with ADRs (12.6 ± 1.2 days) with respect to men (11.8± 0.83 days). Using the Naranjo score, we documented a probable association in 78% of these reactions, while DIPS revealed that about 22% of ADRs were related to DDIs. Patients with ADRs received 3052 prescriptions on 11,138 (27.4%) having a mean of 6.1±0.29 drugs that was significantly higher (P<0.01) with respect to patients not experiencing ADRs (mean of 3.4±0.13 drugs). About 19% of ADRs were not diagnosed and were treated as new diseases. Our results indicate that drug administration induces the development of ADRs also during the hospitalization, particularly in elderly women. Moreover, we also documented that ADRs in some patients are under-diagnosed, therefore, it is important to motivate healthcare to report the ADRs in order to optimize the patients' safety.

Full text: Since Rosenberg's initial discovery, cisplatin has become one of the most effective anticancer drugs, with particular significance in head and neck cancer. For advanced disease, where the tumour is unresectable, radiotherapy and chemotherapy, either singularly or combined, remain the possible therapeutic modalities. The majority of the trials using a combination of cisplatin and radiation obtained much better results than the single-agent trials. But the best schedule, dosage and timing between radiation and drug administration are still unknown. Many positive steps were however made to eliminate the cisplatin-produced side effects, as much as possible. The tendency in current trials is to fractionate the drug dose by daily administration and also to hyperfractionate the radiation. In this way the long-term benefits are improved and the toxicity is better tolerated

Mixed immunotherapy and chemotherapy of tumours is one of the most efficient ways to improve cancer treatment strategies. However, it is important to 'design' an effective treatment programme which can optimize the ways of combining immunotherapy and chemotherapy to diminish their imminent side effects. Control engineering techniques could be used for this. The method of multiple model predictive controller (MMPC) is applied to the modified Stepanova model to induce the best combination of drugs scheduling under a better health criteria profile. The proposed MMPC is a feedback scheme that can perform global optimization for both tumour volume and immune competent cell density by performing multiple constraints. Although current studies usually assume that immunotherapy has no side effect, this paper presents a new method of mixed drug administration by employing MMPC, which implements several constraints for chemotherapy and immunotherapy by considering both drug toxicity and autoimmune. With designed controller we need maximum 57% and 28% of full dosage of drugs for chemotherapy and immunotherapy in some instances, respectively. Therefore, through the proposed controller less dosage of drugs are needed, which contribute to suitable results with a perceptible reduction in medicine side effects. It is observed that in the presence of MMPC, the amount of required drugs is minimized, while the tumour volume is reduced. The efficiency of the presented method has been illustrated through simulations, as the system from an initial condition in the malignant region of the state space (macroscopic tumour volume) transfers into the benign region (microscopic tumour volume) in which the immune system can control tumour growth.

Mass drug administration for elimination of Plasmodium falciparum malaria is recommended by WHO in some settings. We used consensus modelling to understand how to optimise the effects of mass drug administration in areas with low malaria transmission. We collaborated with researchers doing field trials to establish a standard intervention scenario and standard transmission setting, and we input these parameters into four previously published models. We then varied the number of rounds of mass drug administration, coverage, duration, timing, importation of infection, and pre-administration transmission levels. The outcome of interest was the percentage reduction in annual mean prevalence of P falciparum parasite rate as measured by PCR in the third year after the final round of mass drug administration. The models predicted differing magnitude of the effects of mass drug administration, but consensus answers were reached for several factors. Mass drug administration was predicted to reduce transmission over a longer timescale than accounted for by the prophylactic effect alone. Percentage reduction in transmission was predicted to be higher and last longer at lower baseline transmission levels. Reduction in transmission resulting from mass drug administration was predicted to be temporary, and in the absence of scale-up of other interventions, such as vector control, transmission would return to pre-administration levels. The proportion of the population treated in a year was a key determinant of simulated effectiveness, irrespective of whether people are treated through high coverage in a single round or new individuals are reached by implementation of several rounds. Mass drug administration was predicted to be more effective if continued over 2 years rather than 1 year, and if done at the time of year when transmission is lowest. Mass drug administration has the potential to reduce transmission for a limited time, but is not an effective replacement for existing

NRC comprehensive records disposition schedule
International Nuclear Information System (INIS)
1992-03-01
Title 44 United States Code, ''Public Printing and Documents,'' regulations cited in the General Services Administration's (GSA) ''Federal Information Resources Management Regulations'' (FIRMR), Part 201-9, ''Creation, Maintenance, and Use of Records,'' and regulation issued by the National Archives and Records Administration (NARA) in 36 CFR Chapter XII, Subchapter B, ''Records Management,'' require each agency to prepare and issue a comprehensive records disposition schedule that contains the NARA approved records disposition schedules for records unique to the agency and contains the NARA's General Records Schedules for records common to several or all agencies. The approved records disposition schedules specify the appropriate duration of retention and the final disposition for records created or maintained by the NRC. NUREG-0910, Rev. 2, contains ''NRC's Comprehensive Records Disposition Schedule,'' and the original authorized approved citation numbers issued by NARA. Rev. 2 totally reorganizes the records schedules from a functional arrangement to an arrangement by the host office. A subject index and a conversion table have also been developed for the NRC schedules to allow staff to identify the new schedule numbers easily and to improve their ability to locate applicable schedules

Development of Watch Schedule Using Rules Approach
Jurkevicius, Darius; Vasilecas, Olegas
The software for schedule creation and optimization solves a difficult, important and practical problem. The proposed solution is an online employee portal where administrator users can create and manage watch schedules and employee requests. Each employee can login with his/her own account and see his/her assignments, manage requests, etc. Employees set as administrators can perform the employee scheduling online, manage requests, etc. This scheduling software allows users not only to see the initial and optimized watch schedule in a simple and understandable form, but also to create special rules and criteria and input their business. The system using rules automatically will generate watch schedule.

Concomitant administration of bevacizumab and pemetrexed-cisplatin is a common treatment for advanced nonsquamous non-small cell lung cancer (NSCLC). Vascular normalization following bevacizumab administration may transiently enhance drug delivery, suggesting improved efficacy with sequential administration. To investigate optimal scheduling, we conducted a study in NSCLC-bearing mice. First, experiments demonstrated improved efficacy when using sequential vs. concomitant scheduling of bevacizumab and chemotherapy. Combining this data with a mathematical model of tumor growth under therapy accounting for the normalization effect, we predicted an optimal delay of 2.8 days between bevacizumab and chemotherapy. This prediction was confirmed experimentally, with reduced tumor growth of 38% as compared to concomitant scheduling, and prolonged survival (74 vs. 70 days). Alternate sequencing of 8 days failed in achieving a similar increase in efficacy, thus emphasizing the utility of modeling support to identify optimal scheduling. The model could also be a useful tool in the clinic to personally tailor regimen sequences. © 2017 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

In 2013, the Advisory Committee of the Food and Drug Administration determined hydrocodone combination medications (HCMs) needed tighter regulation due to high abuse potential; they recommended upscheduling HCMs from Schedule III to II. The purpose of this study was to examine the effect of upscheduling of HCMs on pain management practices of advanced practiced registered nurses (APRNs) in Oklahoma. In this qualitative study, 25 participants described their primary care experiences after the upscheduling. A thematic analysis was used to understand the effects on APRN pain management practices. The upscheduling of HCMs has greatly affected the pain management practices of APRNs in a state where Schedule II narcotic prescribing is forbidden. Findings will assist APRNs with improving patient access to care, implementing practice regulations, and exploring options for alternative pain therapies in primary care. Upscheduling of HCMs has had a severe impact on APRNs, affecting their prescribing practices and leading to increased referrals. They noted limited treatment options, increased health care costs, and decreased access to care. The APRNs understand the problem of prescription opioid abuse, diversion, and misuse. A consensus model could standardize the regulatory process for APRNs, increase interstate mobility for practice, and increase access to APRN care nationwide.

Drugs are introduced into the body by numerous routes such as enteral (oral, sublingual and rectum administration), parenteral (intravascular, intramuscular, subcutaneous and inhalation administration), or topical (skin and mucosal membranes). Each route has specific purposes, advantages and disadvantages. Today, the oral route remains the preferred one for different reasons such as ease and compliance by patients. Several nanoformulated drugs have been already approved by the FDA, such as Abelcet®, Doxil®, Abraxane® or Vivagel®(Starpharma) which is an anionic G4-poly(L-lysine)-type dendrimer showing potent topical vaginal microbicide activity. Numerous biochemical studies, as well as biological and pharmacological applications of both dendrimer based products (dendrimers as therapeutic compounds per se, like Vivagel®) and dendrimers as drug carriers (covalent conjugation or noncovalent encapsulation of drugs) were described. It is widely known that due to their outstanding physical and chemical properties, dendrimers afforded improvement of corresponding carried-drugs as dendrimer-drug complexes or conjugates (versus plain drug) such as biodistribution and pharmacokinetic behaviors. The purpose of this manuscript is to review the recent progresses of dendrimers as nanoscale drug delivery systems for the delivery of drugs using enteral, parenteral and topical routes. In particular, we focus our attention on the emerging and promising routes such as oral, transdermal, ocular and transmucosal routes using dendrimers as delivery systems.

Estimating preferences for modes of drug administration: The case of US healthcare professionals.
Tetteh, Ebenezer K; Morris, Steve; Titchener-Hooker, Nigel
2018-01-01
There are hidden drug administration costs that arise from a mismatch between end-user preferences and how manufacturers choose to formulate their drug products for delivery to patients. The corollary of this is: there are "intangible benefits" from considering end-user preferences in manufacturing patient-friendly medicines. It is important then to have some idea of what pharmaceutical manufacturers should consider in making patient-friendly medicines and of the magnitude of the indirect benefits from doing so. This study aimed to evaluate preferences of healthcare professionals in the US for the non-monetary attributes of different modes of drug administration. It uses these preference orderings to compute a monetary valuation of the indirect benefits from making patient-friendly medicines. A survey collected choice preferences of a sample of 210 healthcare professionals in the US for two unlabelled drug options. These drugs were identical except in the levels of attributes of drug administration. Using the choice data collected, statistical models were estimated to compute gross welfare benefits, measured by the expected compensating variation, from making drugs in a more patient-friendly manner. The monetary value of end-user benefits from developing patient-friendly drug delivery systems is: (1) as large as the annual acquisition costs per full treatment episode for some biologic drugs; and (2) likely to fall in the "high end" of the distribution of the direct monetary costs of drug administration. An examination of end-user preferences should help manufacturers make more effective and efficient use of limited resources for innovations in drug delivery system, or manufacturing research in general.

FDA approves efavirenz. Food and Drug Administration.
Highleyman, L
1998-10-01
The Food and Drug Administration (FDA) approved DuPont Pharma's new non-nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (Sustiva, DMP-266). Efavirenz has shown promise in trials with over 2000 participants for up to 24 weeks, and early data suggests it may be as effective as protease inhibitors when used in a combination regimen. It is the first anti-HIV drug approved for once-daily dosing. Efavirenz is well tolerated, and the main side effects reported are dizziness, insomnia, abnormal dreams, and skin rash. Efavirenz has been approved for adults and children, but should not be used by pregnant women. Contact information is provided.

This double-blind, placebo-controlled study investigated the effects of oral morphine (0, 45, 135 mg/70 kg) and oral oxycodone (0, 15, 45 mg/70 kg) on buprenorphine-maintained opioid addicts. As a 3: 1 morphine : oxycodone oral dose ratio yielded equivalent subjective and physiological effects in nondependent individuals, this ratio was used in the present study. Two self-administration laboratory procedures - that is, a drug versus money and a drug versus drug procedure - were assessed. Study participants (N=12) lived in the hospital and were maintained on 4 mg/day sublingual buprenorphine. When participants chose between drug and money, money was preferred over all drug doses; only high-dose oxycodone was self-administered more than placebo. When participants chose between drug and drug, both drugs were chosen more than placebo, high doses of each drug were chosen over low doses, and high-dose oxycodone was preferred over high-dose morphine. The subjective, performance-impairing, and miotic effects of high-dose oxycodone were generally greater than those of high-dose morphine. The study demonstrated that a 3: 1 oral dose ratio of morphine : oxycodone was not equipotent in buprenorphine-dependent individuals. Both self-administration procedures were effective for assessing the relative reinforcing effects of drugs; preference for one procedure should be driven by the specific research question of interest.

Topical administration is an appealing method for drug delivery due to its non-invasiveness, self-controlled application, avoidance of first-pass metabolism in the liver and reduction of systemic side effects compared to other conventional routes such as oral and parenteral. However, topical administration must overcome the permeable barriers that skin and mucosa represent for the drug to achieve its desired therapeutic effect. Penetration of drugs through human skin is mainly impaired by the stratum corneum- the uppermost keratinized skin layer. In contrast, the stratified squamous epithelium (a nonkeratinized tissue) represents the major physical barrier for transbuccal drug administration in humans. Different technologies have been studied to enhance the bioavailability or local effects of drugs administered through skin and buccal mucosa. Those technologies involve the use of physical or chemical enhancers and new dosage forms such as vesicles, cyclodextrins, nanoparticles and other complex systems. Combinations of these technologies may further increase drug delivery in some cases. As analgesia is one of the main therapeutic effects sought through topical administration, this paper focuses on the review of drug delivery systems to improve the topical and transdermal/transbuccal drug delivery of substances with known analgesic action. A discussion of their possibilities and limitations is also included.

This paper is a consolidated report on ten major planning and scheduling systems that have been developed by the National Aeronautics and Space Administration (NASA). A description of each system, its components, and how it could be potentially used in private industry is provided in this paper. The planning and scheduling technology represented by the systems ranges from activity based scheduling employing artificial intelligence (AI) techniques to constraint based, iterative repair scheduling. The space related application domains in which the systems have been deployed vary from Space Shuttle monitoring during launch countdown to long term Hubble Space Telescope (HST) scheduling. This paper also describes any correlation that may exist between the work done on different planning and scheduling systems. Finally, this paper documents the lessons learned from the work and research performed in planning and scheduling technology and describes the areas where future work will be conducted.

Aim of this study is to determine the levels of knowledge related with drug administration and drug administration errors of nurses who care for pediatric patients. The study data were obtained from the nurses who were working in the departments of pediatrics in two education and research hospitals in the province of İstanbul and who accepted to participate in the study. The questionnaire form of the study was established by the investigators in accordance with the experiences and literature information. A total of 31 questions related with drug preparation, calculation and administration together with the general working properties of the individual were filled out by face to face interview. The data were evaluated using percent and chi-square tests. The study was initiated after ethics committee approval was obtained from Şişli Hamidiye Etfal Education and Research Hospital (365/2013). The study was conducted with 98 nurses who accepted the questionnaire. The education levels of the participants were as follows: undergraduate (48%), high school (32.7%), associate degree (12.2%), master's degree (6.1%) and postgraduate (1%). It was found that 88.8% of the participants worked in a patient-centered fashion and 11.2% worked in a work-centered fashion. The frequency of interruption/distraction during preparation of treatment was found to be 92.9%. It was found that the frequency of checking by two people during preparation or administration of high risk drugs was 64.3% and the conditions under which drugs should be kept were found to known correctly with a rate of 76.5%. It was found that undergraduate healthcare workers were more successful in converting units (p= 0.000). It was found that powder weight of drugs was considered with a rate of 85.7% in calculation. Conclusively, it was found that nurses who worked in pediatric wards did not receive a standard education in terms of drug administration and preparation. It was found that undergraduate nurses were more

Full Text Available During the past 20 years advances in drug formulations and innovative routes of administration have been made. Our understanding of drug transport across tissues has increased. These changes have often resulted in improved patient adherence to the therapeutic regiment and pharmacologic response. The administration of drugs by transdermal or transmucosal routes offers the advantage of being relatively painless. Also, the potential for greater flexibility in a variety of clinical situations exists, often precluding the need to establish intravinus access which is a particular benefit for children. This statement focuses on the advantages and disadvantages of alternative routes of drug administration. Issues of particular importance in the care of pediatric patients especially factors that could lead to drug-relaxed toxicity or adverse responses are emphasized.Key words: drug formulation, pharmacoKINETICS, pharmacodynamics, drug, children.

Direct information on the distribution of a drug requires measurements in various tissues. Such data have until now been obtained in animals, or have indirectly been calculated from plasma measurements in humans using mathematical models. Here we suggest the use of positron emission tomography (PET) as a method to obtain direct measurements of drug distribution in the human body. The distribution in body and brain of vinpocetine, a neuroprotective drug widely used in the prevention and treatment of cerebrovascular diseases, was followed after oral administration. Vinpocetine was labelled with carbon-11 and radioactivity was measured by PET in stomach, liver, brain and kidney in six healthy volunteers. The radioactivity in blood and urine as well as the fractions of [ 11 C]vinpocetine and labelled metabolites in plasma were also determined. After oral administration, [ 11 C]vinpocetine appeared immediately in the stomach and within minutes in the liver and the blood. In the blood the level of radioactivity continuously increased until the end of the measurement period, whereas the fraction of the unchanged mother compound decreased. Radioactivity uptake and distribution in the brain were demonstrable from the tenth minute after the administration of the labelled drug. Brain distribution was heterogeneous, similar to the distribution previously reported after intravenous administration. These findings indicate that vinpocetine, administered orally in humans, readily enters the bloodstream from the stomach and gastrointestinal tract and, consequently, passes the blood-brain barrier and enters the brain. Radioactivity from [ 11 C]vinpocetine was also demonstrated in the kidneys and in urine, indicating that at least a part of the radioactive drug and labelled metabolites is eliminated from the body through the kidneys. This study is the first to demonstrate that PET might be a useful, direct and non-invasive tool to study the distribution and pharmacokinetics of orally

Pharmacists correcting schedule II prescriptions: DEA flip-flops continue.
Abood, Richard R
2010-12-01
The Drug Enforcement Administration (DEA) has in recent years engaged in flip-flopping over important policy decisions. The most recent example involved whether a pharmacist can correct a written schedule II prescription upon verification with the prescriber. For several years the DEA's policy permitted this practice. Then the DEA issued a conflicting policy statement in 2007 in the preamble to the multiple schedule II prescription regulation, causing a series of subsequent contradictory statements ending with the policy that pharmacists should follow state law or policy until the Agency issues a regulation. It is doubtful that the DEA's opinion in the preamble would in itself constitute legal authority, or that the Agency would try to enforce the opinion. Nonetheless, these flip-flop opinions have confused pharmacists, caused some pharmacies to have claims rejected by third party payors, and most likely have inconvenienced patients.

The Administrator of the Drug Enforcement Administration is issuing this notice of intent to temporarily schedule six synthetic cannabinoids: methyl 2-(1-(5-fluoropentyl)-1H-indazole-3-carboxamido)-3,3-dimethylbutanoate [5F-ADB; 5F-MDMB-PINACA]; methyl 2-(1-(5-fluoropentyl)-1H-indazole-3-carboxamido)-3-methylbutanoate [5F-AMB]; N-(adamantan-1-yl)-1-(5-fluoropentyl)-1H-indazole-3-carboxamide [5F-APINACA, 5F-AKB48]; N-(1-amino-3,3-dimethyl-1-oxobutan-2-yl)-1-(4-fluorobenzyl)-1H-indazole-3-carboxamide [ADB-FUBINACA]; methyl 2-(1-(cyclohexylmethyl)-1H-indole-3-carboxamido)-3,3-dimethylbutanoate [MDMB-CHMICA, MMB-CHMINACA] and methyl 2-(1-(4-fluorobenzyl)-1H-indazole-3-carboxamido)-3,3-dimethylbutanoate [MDMB-FUBINACA], into schedule I pursuant to the temporary scheduling provisions of the Controlled Substances Act (CSA). This action is based on a finding by the Administrator that the placement of these synthetic cannabinoids into schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. Any final order will impose the administrative, civil, and criminal sanctions and regulatory controls applicable to schedule I substances under the Controlled Substances Act on the manufacture, distribution, possession, importation, exportation of, and research and conduct with, instructional activities of these synthetic cannabinoids.

Cocaine self-administration in social dyads using custom-built operant conditioning chambers.
Lacy, Ryan T; Strickland, Justin C; Smith, Mark A
2014-10-30
Traditionally, the analysis of intravenous drug self-administration is limited to conditions in which subjects are tested in isolation. This limits the translational appeal of these studies because drug use in humans often occurs in the presence of others. We used custom-built operant conditioning chambers that allowed social dyads visual, olfactory, auditory, and limited tactile contact while concurrently self-administering cocaine. Male rats were trained to respond according to a fixed interval schedule of reinforcement (with a limited hold) in order to determine if patterns of cocaine (0.75mg/kg/infusion) self-administration became more similar over time in social pairs. Cocaine self-administration was tested across five days according to a 10-min fixed interval schedule (with a 5-min limited hold). Quarter-life values (time at which 25% of responses were emitted per interval) were analyzed using intraclass correlations. The total number of reinforcers obtained did not vary across the five days of testing; however, quarter-life values became progressively more similar between individuals within the social dyads. Standard operant conditioning chambers are unable to assess responding in multiple animals due to their small size, the need to prevent subjects from responding on the lever of their partner, and the need to prevent infusion lines from entangling. By using custom-built social operant conditioning chambers, we assessed the effects of social contact on cocaine self-administration. Social operant conditioning chambers can be used as a preclinical method to examine social influences on drug self-administration under conditions that approximate human substance use.

Scheduling nursing personnel on a microcomputer.
Liao, C J; Kao, C Y
1997-01-01
Suggests that with the shortage of nursing personnel, hospital administrators have to pay more attention to the needs of nurses to retain and recruit them. Also asserts that improving nurses' schedules is one of the most economic ways for the hospital administration to create a better working environment for nurses. Develops an algorithm for scheduling nursing personnel. Contrary to the current hospital approach, which schedules nurses on a person-by-person basis, the proposed algorithm constructs schedules on a day-by-day basis. The algorithm has inherent flexibility in handling a variety of possible constraints and goals, similar to other non-cyclical approaches. But, unlike most other non-cyclical approaches, it can also generate a quality schedule in a short time on a microcomputer. The algorithm was coded in C language and run on a microcomputer. The developed software is currently implemented at a leading hospital in Taiwan. The response to the initial implementation is quite promising.

The hypocretin/orexin (HCRT) neuropeptide system regulates feeding, arousal state, stress responses, and reward, especially under conditions of enhanced motivational relevance. In particular, HCRT neurotransmission facilitates drug-seeking behavior in circumstances that demand increased effort and/or motivation to take the drug. The present study used a shRNA-encoding adeno-associated viral vector to knockdown Hcrt expression throughout the dorsal hypothalamus in adult rats and determine the role of HCRT in cocaine self-administration. Chronic Hcrt silencing did not impact cocaine self-administration under short-access conditions, but robustly attenuated cocaine intake under extended access conditions, a model that mimics key features of compulsive cocaine taking. In addition, Hcrt silencing decreased motivation for both cocaine and a highly palatable food reward (i.e., sweetened condensed milk; SCM) under a progressive ratio schedule of reinforcement, but did not alter responding for SCM under a fixed ratio schedule. Importantly, Hcrt silencing did not affect food or water consumption, and had no consequence for general measures of arousal and stress reactivity. At the molecular level, chronic Hcrt knockdown reduced the number of neurons expressing dynorphin (DYN), and to a smaller extent melanin-concentrating hormone (MCH), in the dorsal hypothalamus. These original findings support the hypothesis that HCRT neurotransmission promotes operant responding for both drug and non-drug rewards, preferentially under conditions requiring a high degree of motivation. Furthermore, the current study provides compelling evidence for the involvement of the HCRT system in cocaine self-administration also under low-effort conditions in rats allowed extended access, possibly via functional interactions with DYN and MCH signaling.

To clinically evaluate a new patented multimodal system (SAFERSleep) designed to reduce errors in the recording and administration of drugs in anaesthesia. Prospective randomised open label clinical trial. Five designated operating theatres in a major tertiary referral hospital. Eighty nine consenting anaesthetists managing 1075 cases in which there were 10,764 drug administrations. Use of the new system (which includes customised drug trays and purpose designed drug trolley drawers to promote a well organised anaesthetic workspace and aseptic technique; pre-filled syringes for commonly used anaesthetic drugs; large legible colour coded drug labels; a barcode reader linked to a computer, speakers, and touch screen to provide automatic auditory and visual verification of selected drugs immediately before each administration; automatic compilation of an anaesthetic record; an on-screen and audible warning if an antibiotic has not been administered within 15 minutes of the start of anaesthesia; and certain procedural rules-notably, scanning the label before each drug administration) versus conventional practice in drug administration with a manually compiled anaesthetic record. Primary: composite of errors in the recording and administration of intravenous drugs detected by direct observation and by detailed reconciliation of the contents of used drug vials against recorded administrations; and lapses in responding to an intermittent visual stimulus (vigilance latency task). Secondary: outcomes in patients; analyses of anaesthetists' tasks and assessments of workload; evaluation of the legibility of anaesthetic records; evaluation of compliance with the procedural rules of the new system; and questionnaire based ratings of the respective systems by participants. The overall mean rate of drug errors per 100 administrations was 9.1 (95% confidence interval 6.9 to 11.4) with the new system (one in 11 administrations) and 11.6 (9.3 to 13.9) with conventional methods (one

Radiopharmaceutical regulation and Food and Drug Administration policy.
Rotman, M; Laven, D; Levine, G
1996-04-01
The regulatory policy of the Food and Drug Administration (FDA) on radiopharmaceuticals flows from a rigid, traditional, drug-like interpretation of the FDC Act on the licensing of radiopharmaceuticals. This contributes to significant delays in the drug-approval process for radiopharmaceuticals, which are very costly to the nuclear medicine community and the American public. It seems that radiopharmaceuticals would be better characterized as molecular devices. Good generic rule-making principles include: use of a risk/benefit/cost analysis; intent based on sound science; performance standards prepared by outside experts; a definite need shown by the regulatory agency; to live with the consequences of any erroneous cost estimates; and design individual credential requirements so that additional training results in enhanced professional responsibility. When these common elements are applied to current FDA policy, it seems that the agency is out of sync with the stated goals for revitalizing federal regulatory policies as deemed necessary by the Clinton administration. Recent FDA rulings on positron-emission tomography, Patient Package inserts, and on medical device service accentuate the degree of such asynchronization. Radiopharmaceutical review and licensing flexibility could be dramatically improved by excluding radiopharmaceuticals from the drug category and reviewing them as separate entities. This new category would take into account their excellent record of safety and their lack of pharmacological action. Additionally, their evaluation of efficacy should be based on their ability to provide useful scintiphotos, data, or responses of the physiological system it portends to image, quantitate, or describe. To accomplish the goal of transforming the FDA's rigid, prescriptive policy into a streamlined flexible performance-based policy, the Council on Radionuclides and Radiopharmaceuticals proposal has been presented. In addition, it is suggested that the United

Evaluating the administration costs of biologic drugs: development of a cost algorithm.
Tetteh, Ebenezer K; Morris, Stephen
2014-12-01
Biologic drugs, as with all other medical technologies, are subject to a number of regulatory, marketing, reimbursement (financing) and other demand-restricting hurdles applied by healthcare payers. One example is the routine use of cost-effectiveness analyses or health technology assessments to determine which medical technologies offer value-for-money. The manner in which these assessments are conducted suggests that, holding all else equal, the economic value of biologic drugs may be determined by how much is spent on administering these drugs or trade-offs between drug acquisition and administration costs. Yet, on the supply-side, it seems very little attention is given to how manufacturing and formulation choices affect healthcare delivery costs. This paper evaluates variations in the administration costs of biologic drugs, taking care to ensure consistent inclusion of all relevant cost resources. From this, it develops a regression-based algorithm with which manufacturers could possibly predict, during process development, how their manufacturing and formulation choices may impact on the healthcare delivery costs of their products.

Mephedrone (MMC) is a relatively new recreational drug that has rapidly increased in popularity in recent years. This study explored the characteristics of intravenous MMC self-administration in the rat, with methamphetamine (METH) used as a comparator drug. Male Sprague-Dawley rats were trained to nose poke for intravenous MMC or METH in daily 2 h sessions over a 10 d acquisition period. Dose-response functions were then established under fixed- and progressive-ratio (FR and PR) schedules over three subsequent weeks of testing. Brains were analyzed ex vivo for striatal serotonin (5-HT) and dopamine (DA) levels and metabolites, while autoradiography assessed changes in the regional density of 5-HT and serotonin transporter (SERT) and DA transporter (DAT) and induction of the inflammation marker translocator protein (TSPO). Results showed that MMC was readily and vigorously self-administered via the intravenous route. Under a FR1 schedule, peak responding for MMC was obtained at 0.1 mg/kg/infusion, versus 0.01 mg/kg/infusion for METH. Break points under a PR schedule peaked at 1 mg/kg/infusion MMC versus 0.3 mg/kg/infusion for METH. Final intakes of MMC were 31.3 mg/kg/d compared to 4 mg/kg/d for METH. Rats self-administering MMC, but not METH, gained weight at a slower rate than control rats. METH, but not MMC, self-administration elevated TSPO receptor density in the nucleus accumbens and hippocampus, while MMC, but not METH, self-administration decreased striatal 5-hydroxyindolacetic acid (5-HIAA) concentrations. In summary, MMC supported high levels of self-administration, matching or exceeding those previously reported with other drugs of abuse.

To develop standard operational protocol (SOP) on oral drug administration and checklist to assess the implementation of the developed SOP. In this prospective methodological study, SOPs were developed in five phases. In the first phase, the preliminary draft of SOPs and checklists were prepared based on literature review, assessment of current practices and focus group discussion (FGD) with bedside working nurses. In the second phase, content validity was checked with the help of Delphi technique (12 experts). Total four drafts were prepared in stages and necessary modifications were made as per suggestions after each Delphi round. Fourth Delphi round was performed after conducting a pilot study. In the fourth phase, all bedside nurses were trained as per SOPs and asked to practice accordingly and observation of thirty oral drug administrations in children was done to check reliability of checklists for implementation of SOPs. In Phase-V, 7 FGDs were conducted with bedside nurses to assess the effectiveness of SOPs. The Content Validity Index (CVI) of SOP and checklists was 99.77%. Overall standardized Cronbach's alpha was calculated as 0.94. All the nurses felt that the SOP is useful. Valid and feasible SOP for drug administration to children through oral route along with valid and reliable checklist were developed. It is recommended to use this document for drug administration to children.

Drug overprescription in nursing homes: an empirical evaluation of administrative data.
Stroka, Magdalena A
2016-04-01
A widely discussed shortcoming of long-term care in nursing homes for the elderly is the inappropriate or suboptimal drug utilization, particularly of psychotropic drugs. Using administrative data from the largest sickness fund in Germany, this study was designed to estimate the effect of institutionalization on the drug intake of the frail elderly. Difference-in-differences propensity score matching techniques were used to compare drug prescriptions for the frail elderly who entered a nursing home with those who remained in the outpatient care system; findings suggest that nursing home residents receive more doses of antipsychotics, antidepressants, and analgesics. The potential overprescription correlates with estimated drug costs of about €87 million per year.

Full Text Available The fungus Candida albicans is the most common causative agent of human fungal infections and better drugs or drug combination strategies are urgently needed. Here, we present an agent-based model of the interplay of C. albicans with the host immune system and with the microflora of the host. We took into account the morphological change of C. albicans from the yeast to hyphae form and its dynamics during infection. The model allowed us to follow the dynamics of fungal growth and morphology, of the immune cells and of microflora in different perturbing situations. We specifically focused on the consequences of microflora reduction following antibiotic treatment. Using the agent-based model, different drug types have been tested for their effectiveness, namely drugs that inhibit cell division and drugs that constrain the yeast-to-hyphae transition. Applied individually, the division drug turned out to successfully decrease hyphae while the transition drug leads to a burst in hyphae after the end of the treatment. To evaluate the effect of different drug combinations, doses, and schedules, we introduced a measure for the return to a healthy state, the infection score. Using this measure, we found that the addition of a transition drug to a division drug treatment can improve the treatment reliability while minimizing treatment duration and drug dosage. In this work we present a theoretical study. Although our model has not been calibrated to quantitative experimental data, the technique of computationally identifying synergistic treatment combinations in an agent based model exemplifies the importance of computational techniques in translational research.

Illicit online marketing of lorcaserin before DEA scheduling.
Liang, Bryan A; Mackey, Tim K; Archer-Hayes, Ashley N; Shinn, Linda M
2013-05-01
Antiobesity drugs have been marketed illicitly by "no prescription" online pharmacies after approval and scheduling by the drug enforcement agency. We assess whether antiobesity drug Belviq® (lorcaserin HCl) was available from illicit online vendors before DEA-scheduling when sales are unauthorized. Online searches of "buy Belviq no prescription" examining first five result pages marketing the drug. Searches were performed from 11/5/2012-12/8/2012, prior to DEA scheduing. Belviq® is actively marketed by "no prescription" online vendors despite official unavailability and prescription requirements. Approaches included direct-to-consumer advertising using descriptive website URLs; linking to illicit marketers; and directing customers to other weight-loss websites for additional marketing. Finally, large quantities were marketed by business-to-business vendors. Illicit online "no prescription" pharmacies are marketing unauthorized, suspect antiobesity drugs before DEA scheduling and permitted marketing. Regulators must legally intercede to ensure patient safety, and providers must educate patients about online-sourcing risks. Copyright © 2013 The Obesity Society.

The medication iatrogenic risk is quite unevaluated in neonatology Objective: Assessment of errors that occurred during the preparation and administration of injectable medicines in a neonatal unit in order to implement corrective actions to reduce the occurrence of these errors. A prospective, observational study was performed in a neonatal unit over a period of one month. The practice of preparing and administering injectable medications were identified through a standardized data collection form. These practices were compared with summaries of the characteristics of each product (RCP) and the bibliography. One hundred preparations were observed of 13 different drugs. 85 errors during preparations and administration steps were detected. These errors were divided into preparation errors in 59% of cases such as changing the dilution protocol (32%), the use of bad solvent (11%) and administration errors in 41% of cases as errors timing of administration (18%) or omission of administration (9%). This study showed a high rate of errors during stages of preparation and administration of injectable drugs. In order to optimize the care of newborns and reduce the risk of medication errors, corrective actions have been implemented through the establishment of a quality assurance system which consisted of the development of injectable drugs preparation procedures, the introduction of a labeling system and staff training.

2016-02-01
Full Text Available INTRODUCTION: Anesthesiology is the only medical specialty that prescribes, dilutes, and administers drugs without conferral by another professional. Adding to the high frequency of drug administration, a propitious scenario to errors is created. OBJECTIVE: Access the prevalence of drug administration errors during anesthesia among anesthesiologists from Santa Catarina, the circumstances in which they occurred, and possible associated factors. MATERIALS AND METHODS: An electronic questionnaire was sent to all anesthesiologists from Sociedade de Anestesiologia do Estado de Santa Catarina, with direct or multiple choice questions on responder demographics and anesthesia practice profile; prevalence of errors, type and consequence of error; and factors that may have contributed to the errors. RESULTS: Of the respondents, 91.8% reported they had committed administration errors, adding the total error of 274 and mean of 4.7 (6.9 errors per respondent. The most common error was replacement (68.4%, followed by dose error (49.1%, and omission (35%. Only 7% of respondents reported neuraxial administration error. Regarding circumstances of errors, they mainly occurred in the morning (32.7%, in anesthesia maintenance (49%, with 47.8% without harm to the patient and 1.75% with the highest morbidity and irreversible damage, and 87.3% of cases with immediate identification. As for possible contributing factors, the most frequent were distraction and fatigue (64.9% and misreading of labels, ampoules, or syringes (54.4%. CONCLUSION: Most respondents committed more than one error in anesthesia administration, mainly justified as a distraction or fatigue, and of low gravity.

Development of an opioid self-administration assay to study drug seeking in zebrafish.
Bossé, Gabriel D; Peterson, Randall T
2017-09-29
The zebrafish (Danio rerio) has become an excellent tool to study mental health disorders, due to its physiological and genetic similarity to humans, ease of genetic manipulation, and feasibility of small molecule screening. Zebrafish have been shown to exhibit characteristics of addiction to drugs of abuse in non-contingent assays, including conditioned place preference, but contingent assays have been limited to a single assay for alcohol consumption. Using inexpensive electronic, mechanical, and optical components, we developed an automated opioid self-administration assay for zebrafish, enabling us to measure drug seeking and gain insight into the underlying biological pathways. Zebrafish trained in the assay for five days exhibited robust self-administration, which was dependent on the function of the μ-opioid receptor. In addition, a progressive ratio protocol was used to test conditioned animals for motivation. Furthermore, conditioned fish continued to seek the drug despite an adverse consequence and showed signs of stress and anxiety upon withdrawal of the drug. Finally, we validated our assay by confirming that self-administration in zebrafish is dependent on several of the same molecular pathways as in other animal models. Given the ease and throughput of this assay, it will enable identification of important biological pathways regulating drug seeking and could lead to the development of new therapeutic molecules to treat addiction.

Auersperg, M.; Pogacnik, A.; Kloboves-Prevodnik, V.; Sersa, G.; Cemazar, M.
2006-01-01
Background. Antitumour schedule-dependency of the doxorubicin and vinblastine combination was explored. Materials and methods. Intraperitoneal Ehrlich ascites tumours (EAT) syngeneic to CBA mice were treated with vinblastine or doxorubicin alone, or in combined treatment schedules. Results. Combinations of doxorubicin and vinblastine administered at 48-h, but not at 24-h interval, regardless of the sequence of drugs, significantly reduced the number of tumour cells in the ascites in comparison with all other treatments. In the combined treatment schedules, the predominant morphological changes as well as DNA distribution pattern were dependent on the first drug applied. Regardless of the sequence of the drugs, median survival times of animals did not significantly differ between the treatment groups. Conclusions. The effect of combination of vinblastine and doxorubicin is schedule-dependent. The time interval, but not the sequence of drugs seems to be crucial for the observed effect. The data from preclinical studies are important for planning combined treatment schedules in clinical setting. (author)

RIF-1 tumors, implanted syngeneically in the gastrocnemius muscles of the right hind legs of C3H/Km mice, were treated either with X ray alone, drug alone, or drug and X ray combined. The drugs tested were bleomycin, BCNU, cis-diamminedichloro platinum, adriamycin, cyclophosphamide, and actinomycin-D. All drugs were administered either in the maximum tolerated dose or a dose that causes minimal tumor growth delay. Both drugs and X rays were administered either as a single dose or in five daily fractions. In addition to the single modality controls, seven different schedules of combined modalities were tested. Tumors were measured periodically after treatment in order that the day at which each tumor reached 4 times its initial cross-sectional area, i.e., its size at the time of treatment, could be determined. The effect of treatment on tumors was based upon excess growth delay (GD), i.e., T400% (treated)-T400% (untreated control). Treatment effects for the same combined modality schedules were also determined for normal skin, using the early skin reaction as an endpoint. Dose effect factors (DEF) were computed for all combined modality schedules and were based upon calculated radiation dose equivalents. We also calculated supra-additivity ratios, SR/sub I/ and SR/sub II/, therapeutic gain factors and adjusted therapeutic gain factors. The only drugs to produce significant supra-additivity with X rays were cis-Pt and cyclo

Influences on cocaine tolerance assessed under a multiple conjunctive schedule of reinforcement.
Yoon, Jin Ho; Branch, Marc N
2009-11-01
Under multiple schedules of reinforcement, previous research has generally observed tolerance to the rate-decreasing effects of cocaine that has been dependent on schedule-parameter size in the context of fixed-ratio (FR) schedules, but not under the context of fixed-interval (FI) schedules of reinforcement. The current experiment examined the effects of cocaine on key-pecking responses of White Carneau pigeons maintained under a three-component multiple conjunctive FI (10 s, 30 s, & 120 s) FR (5 responses) schedule of food presentation. Dose-effect curves representing the effects of presession cocaine on responding were assessed in the context of (1) acute administration of cocaine (2) chronic administration of cocaine and (3) daily administration of saline. Chronic administration of cocaine generally resulted in tolerance to the response-rate decreasing effects of cocaine, and that tolerance was generally independent of relative FI value, as measured by changes in ED50 values. Daily administration of saline decreased ED50 values to those observed when cocaine was administered acutely. The results show that adding a FR requirement to FI schedules is not sufficient to produce schedule-parameter-specific tolerance. Tolerance to cocaine was generally independent of FI-parameter under the present conjunctive schedules, indicating that a ratio requirement, per se, is not sufficient for tolerance to be dependent on FI parameter.

Radiation and platinum drug interaction
International Nuclear Information System (INIS)
Nias, A.H.W.
1985-01-01
The ideal platinum drug-radiation interaction would achieve radiosensitization of hypoxic tumour cells with the use of a dose of drug which is completely non-toxic to normal tissues. Electron-affinic agents are employed with this aim, but the commoner platinum drugs are only weakly electron-affinic. They do have a quasi-alkylating action however, and this DNA targeting may account for the radiosensitizing effect which occurs with both pre- and post-radiation treatments. Because toxic drug dosage is usually required for this, the evidence of the biological responses to the drug and to the radiation, as well as to the combination, requires critical analysis before any claim of true enhancement, rather than simple additivity, can be accepted. The amount of enhancement will vary with both the platinum drug dose and the time interval between drug administration and radiation. Clinical schedules may produce an increase in tumour response and/or morbidity, depending upon such dose and time relationships. (author)

Combined Transcriptomics and Metabolomics in a Rhesus Macaque Drug Administration Study
Directory of Open Access Journals (Sweden)
Kevin J. Lee
2014-10-01
Full Text Available We describe a multi-omic approach to understanding the effects that the anti-malarial drug pyrimethamine has on immune physiology in rhesus macaques (Macaca mulatta. Whole blood and bone marrow RNA-Seq and plasma metabolome profiles (each with over 15,000 features have been generated for five naïve individuals at up to seven time-points before, during and after three rounds of drug administration. Linear modelling and Bayesian network analyses are both considered, alongside investigations of the impact of statistical modeling strategies on biological inference. Individual macaques were found to be a major source of variance for both omic data types, and factoring individuals into subsequent modelling increases power to detect temporal effects. A major component of the whole blood transcriptome follows the bone marrow with a time-delay, while other components of variation are unique to each compartment. We demonstrate that pyrimethamine administration does impact both compartments throughout the experiment, but very limited perturbation of transcript or metabolite abundance following each round of drug exposure is observed. New insights into the mode of action of the drug are presented in the context of pyrimethamine’s predicted effect on suppression of cell division and metabolism in the immune system.

Full Text Available Antiangiogenics administration in colorectal cancer patients seemed promising therapeutic approach. Inspite of early encouraging results, it however gave only modest clinical benefits. When AAG was administered with discontinuous schedule, the disease showed acceleration in certain cases. Though resistance to AAG has been extensively studied, it is not documented for discontinuous schedules. To simulate clinical situations, we subjected a patient-derived CRC subcutaneous xenograft in mice to three different protocols: 1 AAG (bevacizumab treatment for 30 days (group A (group B was the control, 2 bevacizumab treatment for 50 days (group C and bevacizumab for 30 days and 20 without treatment (group D, and 3 bevacizumab treatment for 70 days (group E and 70 days treatment with a drug-break period between day 30 and 50 (group F. The tumor growth was monitored, and at sacrifice, the vascularity of tumors was measured and the proangiogenic factors quantified. Tumor phenotype was studied by quantifying cancer stem cells. Interrupting bevacizumab during treatment accelerated tumor growth and revascularization. A significant increase of proangiogenic factors was observed when therapy was stopped. On withdrawal of bevacizumab, as also after the drug-break period, the plasmatic VEGF increased significantly. Similarly, a notable increase of CSCs after the withdrawal and drug-break period of bevacizumab was observed (P<.01. The present study indicates that bevacizumab treatment needs to be maintained because discontinuous schedules tend to trigger tumor regrowth, and increase tumor resistance and CSC heterogeneity.

The aim of this paper is to establish a novel method to calculate the extent and amount of drug transported to brain after administration. The cerebrospinal fluid (CSF) was chosen as the target region. The intranasal administration of meptazinol hydrochloride (MEP) was chosen as the model administration and intravenous administration was selected as reference. According to formula transform, the extent was measured by the equation of X(A)CSF, infinity/X0 = Cl(CSF) AUC(0-->infinity)CSF/X0 and the drug amount was calculated by multiplying the dose with the extent. The drug clearance in CSF (Cl(CSF)) was calculated by a method, in which a certain volume of MEP solution was injected directly into rat cistern magna and then clearance was assessed as the reciprocal of the zeroth moment of a CSF level-time curve normalized for dose. In order to testify the accurateness of the method, 14C-sucrose was chosen as reference because of its impermeable characteristic across blood-brain barrier (BBB). It was found out that the MEP concentrations in plasma and CSF after intranasal administration did not show significant difference with those after intravenous administration. However, the extent and amount of MEP transported to CSF was significantly lower compared with those to plasma after these two administrations. In conclusion, the method can be applied to measure the extent and amount of drug transported to CSF, which would be useful to evaluate brain-targeting drug delivery.

Sex differences in the self-administration of cannabinoids and other drugs of abuse.
Fattore, Liana; Fadda, Paola; Fratta, Walter
2009-12-01
Many studies have provided evidence for important sex-dependent differences in the origins, outcomes and treatment of drug abuse and dependence. Preclinical studies typically have employed animal models of addiction, such as oral or intravenous self-administration, to untangle the environmental, neurobiological and genetic factors that contribute to the shift from occasional, recreational use to compulsive, uncontrolled intake of drugs. Craving and relapse of drug seeking in abstinent individuals have also been found to differ between men and women. Identification of the neurobiological basis of craving and drug dependence continues to pose a challenge to addiction research. Significant sex differences are emerging in substance-abuse-related behavior, which has increased the demand for research on how drug consumption may have different causes, progression and consequences in men and women. In keeping with epidemiological data in humans, differences between the two sexes in drug seeking and intake have been well-documented in animal studies, with most recent findings related to abuse of cannabinoids. Clinical and preclinical findings indicate that sex and gonadal hormones may account for individual differences in susceptibility to the reinforcing effects of addictive substances, and that differences in vulnerability to drug abuse may be mediated by the same biological mechanisms. This review focuses on the differences between males and females in relation to drug self-administration and how such behavior may be affected by hormonal status.

The process for drug approval in the United States is complex and time-consuming. There are comparatively few drugs with U.S. Food and Drug Administration (FDA)-approved indications for obstetric use in this country at this time; however, several are under development. We review the process for drug approval and recount the approval histories of obstetric drugs reviewed in the recent past. We also outline the current status of two progestational agents that are under development. For a variety of reasons, including a small market compared with others such as cardiology or oncology, and the potential of being drawn into medical-legal litigation, sponsors are disinclined to pursue drug development for obstetric purposes in this country. We compare the procedures for review and approval of drugs in the United States with those in Europe, and note that recent changes within the FDA may result in not only more drugs being approved but also changes in labeling of already approved drugs. Special programs to facilitate drug development and reforms to modernize the process and improve safety are discussed. These may result in changes in labeling of already approved drugs. Obstacles such as funding and liability are also discussed.

We have developed an animal model of alcohol self-administration that initially employs schedule-induced polydipsia (SIP) to establish reliable ethanol consumption under open access (22 h/d) conditions with food and water concurrently available. SIP is an adjunctive behavior that is generated by constraining access to an important commodity (e.g., flavored food). The induction schedule and ethanol polydipsia generated under these conditions affords the opportunity to investigate the development of drinking typologies that lead to chronic, excessive alcohol consumption. Adult male cynomolgus monkeys (Macaca fascicularis) were induced to drink water and 4% (w/v in water) ethanol by a Fixed-Time 300 seconds (FT-300 seconds) schedule of banana-flavored pellet delivery. The FT-300 seconds schedule was in effect for 120 consecutive sessions, with daily induction doses increasing from 0.0 to 0.5 g/kg to 1.0 g/kg to 1.5 g/kg every 30 days. Following induction, the monkeys were allowed concurrent access to 4% (w/v) ethanol and water for 22 h/day for 12 months. Drinking typographies during the induction of drinking 1.5 g/kg ethanol emerged that were highly predictive of the daily ethanol intake over the next 12 months. Specifically, the frequency in which monkeys ingested 1.5 g/kg ethanol without a 5-minute lapse in drinking (defined as a bout of drinking) during induction strongly predicted (correlation 0.91) subsequent ethanol intake over the next 12 months of open access to ethanol. Blood ethanol during induction were highly correlated with intake and with drinking typography and ranged from 100 to 160 mg% when the monkeys drank their 1.5 g/kg dose in a single bout. Forty percent of the population became heavy drinkers (mean daily intakes >3.0 g/kg for 12 months) characterized by frequent "spree" drinking (intakes >4.0 g/kg/d). This model of ethanol self-administration identifies early alcohol drinking typographies (gulping the equivalent of 6 drinks) that evolve into

Acute bouts of wheel running decrease cocaine self-administration: Influence of exercise output.
Smith, Mark A; Fronk, Gaylen E; Zhang, Huailin; Magee, Charlotte P; Robinson, Andrea M
Exercise is associated with lower rates of drug use in human populations and decreases drug self-administration in laboratory animals. Most of the existing literature examining the link between exercise and drug use has focused on chronic, long-term exercise, and very few studies have examined the link between exercise output (i.e., amount of exercise) and drug self-administration. The purpose of this study was to examine the effects of acute bouts of exercise on cocaine self-administration, and to determine whether these effects were dependent on exercise output and the time interval between exercise and drug self-administration. Female rats were trained to run in automated running wheels, implanted with intravenous catheters, and allowed to self-administer cocaine on a fixed ratio (FR1) schedule of reinforcement. Immediately prior to each test session, subjects engaged in acute bouts of exercise in which they ran for 0, 30, or 60min at 12m/min. Acute bouts of exercise before test sessions decreased cocaine self-administration in an output-dependent manner, with the greatest reduction in cocaine intake observed in the 60-min exercise condition. Exercise did not reduce cocaine self-administration when wheel running and test sessions were separated by 12h, and exercise did not reduce responding maintained by food or responding during a saline substitution test. These data indicate that acute bouts of exercise decrease cocaine self-administration in a time- and output-dependent manner. These results also add to a growing body of literature suggesting that physical activity may be an effective component of drug abuse treatment programs. Copyright © 2016 Elsevier Inc.

Prescription Drug Promotion from 2001-2014: Data from the U.S. Food and Drug Administration.
Directory of Open Access Journals (Sweden)
Helen W Sullivan
Full Text Available The volume of prescription drug promotion over time is often measured by assessing changes in ad spending. However, this method obscures the fact that some types of advertising are more expensive than others. Another way to measure the changes in prescription drug promotion over time is to assess the number of promotional pieces submitted to the U.S. Food and Drug Administration (FDA. Form FDA 2253 collects information such as the date submitted and the type of material submitted. We analyzed data from Forms FDA 2253 received from 2001-2014. We examined the frequency of submissions by audience (consumer and healthcare professional and type of promotional material. There was a noted increase in prescription drug promotion submissions across all media in the early 2000s. Although non-Internet promotion submissions have since plateaued, Internet promotion continued to increase. These results can help public health advocates and regulators focus attention and resources.

Full Text Available The analysis of electronic health records for an automated detection of adverse drug reactions is an approach to solve the problems that arise from traditional methods like spontaneous reporting or manual chart review. Algorithms addressing this task should be modeled on the criteria for a standardized case causality assessment defined by the World Health Organization. One of these criteria is the temporal relationship between drug intake and the occurrence of a reaction or a laboratory test abnormality. Appropriate data that would allow for developing or validating related algorithms is not publicly available, though.In order to provide such data, retrospective routine data of drug administrations and temporally corresponding laboratory observations from a university clinic were extracted, transformed and evaluated by experts in terms of a reasonable time relationship between drug administration and lab value alteration.The result is a data corpus of 400 episodes of normalized laboratory parameter values in temporal context with drug administrations. Each episode has been manually classified whether it contains data that might indicate a temporal correlation between the drug administration and the change of the lab value course, whether such a change is not observable or whether a decision between those two options is not possible due to the data. In addition, each episode has been assigned a concordance value which indicates how difficult it is to assess. This is the first open data corpus of a computable ground truth of temporal correlations between drug administration and lab value alterations.The main purpose of this data corpus is the provision of data for further research and the provision of a ground truth which allows for comparing the outcome of other assessments of this data with the outcome of assessments made by human experts. It can serve as a contribution towards systematic, computerized ADR detection in retrospective data. With

Prohibited or regulated? LSD psychotherapy and the United States Food and Drug Administration.
Oram, Matthew
2016-09-01
Over the 1950s and early 1960s, the use of the hallucinogenic drug lysergic acid diethylamide (LSD) to facilitate psychotherapy was a promising field of psychiatric research in the USA. However, during the 1960s, research began to decline, before coming to a complete halt in the mid-1970s. This has commonly been explained through the increase in prohibitive federal regulations during the 1960s that aimed to curb the growing recreational use of the drug. However, closely examining the Food and Drug Administration's regulation of LSD research in the 1960s will reveal that not only was LSD research never prohibited, but that the administration supported research to a greater degree than has been recognized. Instead, the decline in research reflected more complex changes in the regulation of pharmaceutical research and development. © The Author(s) 2016.

Modeling of corneal and retinal pharmacokinetics after periocular drug administration.
Amrite, Aniruddha C; Edelhauser, Henry F; Kompella, Uday B

the SD rat corneas. Similar pharmacokinetics models explain drug delivery to the cornea in rat and rabbit animal models. Retinal pharmacokinetics after periocular drug administration can be explained with a four-compartment (periocular space, choroid-containing transfer compartment, retina, and distribution compartment) model with elimination from the periocular space, retina, and choroid compartment. Inclusion of a dissolution-release step before the drug is available for absorption or elimination better explains retinal t(max). Good fits were obtained in both the BN (r = 0.99) and SD (r = 0.99) rats for retinal celecoxib using the same model; however, the parameter estimates differed. Corneal and retinal pharmacokinetics of small lipophilic molecules after periocular administration can be described by compartment models. The modeling analysis shows that (1) leak-back from the site of administration most likely contributes to the apparent lack of an increase phase in corneal concentrations; (2) elimination via the conjunctival or periocular blood and lymphatic systems contributes significantly to drug clearance after periocular injection; (3) corneal pharmacokinetics of small lipophilic molecules can be explained by using similar models in rats and rabbits; and (4) although there are differences in some retinal pharmacokinetics parameters between the pigmented and nonpigmented rats, the physiological basis of these differences has yet to be ascertained.

While evidence on implementation of medication safety strategies is increasing, reasons for selecting and relinquishing distinct strategies and details on implementation are typically not shared in published literature. We aimed to collect and structure expert information resulting from implementing medication safety strategies to provide advice for decision-makers. Medication safety experts with clinical expertise from thirteen hospitals throughout twelve European and North American countries shared their experience in workshop meetings, on-site-visits and remote structured interviews. We performed an expert-based, in-depth assessment of implementation of best-practice strategies to improve drug prescribing and drug administration. Workflow, variability and recommended medication safety strategies in drug prescribing and drug administration processes. According to the experts, institutions chose strategies that targeted process steps known to be particularly error-prone in the respective setting. Often, the selection was channeled by local constraints such as the e-health equipment and critically modulated by national context factors. In our study, the experts favored electronic prescribing with clinical decision support and medication reconciliation as most promising interventions. They agreed that self-assessment and introduction of medication safety boards were crucial to satisfy the setting-specific differences and foster successful implementation. While general evidence for implementation of strategies to improve medication safety exists, successful selection and adaptation of a distinct strategy requires a thorough knowledge of the institute-specific constraints and an ongoing monitoring and adjustment of the implemented measures.

1998-03-06
The Food and Drug Administration (FDA) published new rules defining conflict of interests between drug companies and medical researchers and clinicians. Certain financial arrangements will need to be disclosed, although the FDA estimates that only one to ten percent of pharmaceutical companies will need to submit disclosures for one or more of their investigators. The purpose of the new rule is to prevent bias in safety and efficacy studies of drugs and medical devices. The full rule is published in the Federal Register.

Drug-addicted individuals show high levels of impulsive choice, characterized by preference for small immediate over larger but delayed rewards. Although the causal relationship between chronic drug use and elevated impulsive choice in humans has been unclear, a small but growing body of literature over the past decade has shown that chronic drug administration in animal models can cause increases in impulsive choice, suggesting that a similar causal relationship may exist in human drug users. This article reviews this literature, with a particular focus on the effects of chronic cocaine administration, which have been most thoroughly characterized. The potential mechanisms of these effects are described in terms of drug-induced neural alterations in ventral striatal and prefrontal cortical brain systems. Some implications of this research for pharmacological treatment of drug-induced increases in impulsive choice are discussed, along with suggestions for future research in this area.

5-FU Metabolism in Cancer and Orally-Administrable 5-FU Drugs
Directory of Open Access Journals (Sweden)
Iwao Sasaki
2010-09-01
Full Text Available 5-Fluorouracil (5-FU is a key anticancer drug that for its broad antitumor activity, as well as for its synergism with other anticancer drugs, has been used to treat various types of malignancies. In chemotherapeutic regimens, 5-FU has been combined with oxaliplatin, irinotecan and other drugs as a continuous intravenous infusion. Recent clinical chemotherapy studies have shown that several of the regimens with oral 5-FU drugs are not inferior compared to those involving continuous 5-FU infusion chemotherapy, and it is probable that in some regimens continuous 5-FU infusion can be replaced by oral 5-FU drugs. Historically, both the pharmaceutical industry and academia in Japan have been involved in the development of oral 5-FU drugs, and this review will focus on the current knowledge of 5-FU anabolism and catabolism, and the available information about the various orally-administrable 5-FU drugs, including UFT, S-1 and capecitabine. Clinical studies comparing the efficacy and adverse events of S-1 and capecitabine have been reported, and the accumulated results should be utilized to optimize the treatment of cancer patients. On the other hand, it is essential to elucidate the pharmacokinetic mechanism of each of the newly-developed drugs, to correctly select the drugs for each patient in the clinical setting, and to further develop optimized drug derivatives.

The 2015 US Food and Drug Administration Pregnancy and Lactation Labeling Rule.
Brucker, Mary C; King, Tekoa L
2017-05-01
As of 2015, the US Food and Drug Administration (FDA) discontinued the pregnancy risk categories (ABCDX) that had been used to denote the putative safety of drugs for use among pregnant women. The ABCDX system has been replaced by the FDA Pregnancy and Lactation Labeling Rule (PLLR) that requires narrative text to describe risk information, clinical considerations, and background data for the drug. The new rule includes 3 overarching categories: 1) pregnancy, which includes labor and birth; 2) lactation; and 3) females and males of reproductive potential. This article reviews the key components of the PLLR and clinical implications, and provides resources for clinicians who prescribe drugs for women of reproductive age. © 2017 by the American College of Nurse-Midwives.

Many anesthetic drug errors result from vial or syringe swaps. Scanning the barcodes on vials before drug preparation, creating syringe labels that include barcodes, and scanning the syringe label barcodes before drug administration may help to prevent errors. In contrast, making syringe labels by hand that comply with the recommendations of regulatory agencies and standards-setting bodies is tedious and time consuming. A computerized system that uses vial barcodes and generates barcoded syringe labels could address both safety issues and labeling recommendations. We measured compliance of syringe labels in multiple operating rooms (ORs) with the recommendations of regulatory agencies and standards-setting bodies before and after the introduction of the Codonics Safe Label System (SLS). The Codonics SLS was then combined with Smart Anesthesia Manager software to create an anesthesia barcode drug administration system, which allowed us to measure the rate of scanning syringe label barcodes at the time of drug administration in 2 cardiothoracic ORs before and after introducing a coffee card incentive. Twelve attending cardiothoracic anesthesiologists and the OR satellite pharmacy participated. The use of the Codonics SLS drug labeling system resulted in >75% compliant syringe labels (95% confidence interval, 75%-98%). All syringe labels made using the Codonics SLS system were compliant. The average rate of scanning barcodes on syringe labels using Smart Anesthesia Manager was 25% (730 of 2976) over 13 weeks but increased to 58% (956 of 1645) over 8 weeks after introduction of a simple (coffee card) incentive (P < 0.001). An anesthesia barcode drug administration system resulted in a moderate rate of scanning syringe label barcodes at the time of drug administration. Further, adaptation of the system will be required to achieve a higher utilization rate.

In hospitals, the nursing staff is often confronted with the problem of the preparation and administration of drugs for their pediatric patients because of the lack of indication, pediatric dosage, and appropriate galenic form. The goal of this study was to give an overview of the nurses' preparation habits in pediatric units and highlight their daily problems. This single-center prospective study was conducted through an observation of the nursing staff during the drug preparation process in medicine, surgery and intensive care units. We included 91 patients (55 boys and 36 girls), with an average age of 6.3 years (youngest child, 10 days old; oldest child, 18 years old). We observed a mean 2.16 drug preparations per patient [1-5]. We collected 197 observation reports regarding 66 injectable drugs and 131 oral drugs (71 liquid forms and 60 solid forms). The majority of these reports concerned central nervous system drugs (63/197), metabolism and digestive system drugs (50/197), and anti-infective drugs (46/197). The study highlights the nurses' difficulties: modification of the solid galenic forms, lack of knowledge on oral liquid form preservation or reconstitution methods, withdrawal of small volumes, and vague and noncompliant labeling. This study led to the creation of a specific working group for pediatrics. This multidisciplinary team meets on a regular basis to work toward improving the current habits to both simplify and secure drug administration to hospitalized children.

Transdermal and Topical Drug Administration in the Treatment of Pain
Directory of Open Access Journals (Sweden)
Wojciech Leppert
2018-03-01
Full Text Available The comprehensive treatment of pain is multidimodal, with pharmacotherapy playing a key role. An effective therapy for pain depends on the intensity and type of pain, the patients’ age, comorbidities, and appropriate choice of analgesic, its dose and route of administration. This review is aimed at presenting current knowledge on analgesics administered by transdermal and topical routes for physicians, nurses, pharmacists, and other health care professionals dealing with patients suffering from pain. Analgesics administered transdermally or topically act through different mechanisms. Opioids administered transdermally are absorbed into vessels located in subcutaneous tissue and, subsequently, are conveyed in the blood to opioid receptors localized in the central and peripheral nervous system. Non–steroidal anti–inflammatory drugs (NSAIDs applied topically render analgesia mainly through a high concentration in the structures of the joint and a provision of local anti–inflammatory effects. Topically administered drugs such as lidocaine and capsaicin in patches, capsaicin in cream, EMLA cream, and creams containing antidepressants (i.e., doxepin, amitriptyline act mainly locally in tissues through receptors and/or ion channels. Transdermal and topical routes offer some advantages over systemic analgesic administration. Analgesics administered topically have a much better profile for adverse effects as they relieve local pain with minimal systemic effects. The transdermal route apart from the above-mentioned advantages and provision of long period of analgesia may be more convenient, especially for patients who are unable to take drugs orally. Topically and transdermally administered opioids are characterised by a lower risk of addiction compared to oral and parenteral routes.

This study describes the potential of solid lipid nanoparticles and nanostructured lipid carriers as nano-formulations to administer to the central nervous system poorly water soluble drugs. Different neuroactive drugs, i.e. dimethylfumarate, retinyl palmitate, progesterone and the endocannabinoid hydrolysis inhibitor URB597 have been studied. Lipid nanoparticles constituted of tristearin or tristearin in association with gliceryl monoolein were produced. The nanoencapsulation strategy allowed to obtain biocompatible and non-toxic vehicles, able to increase the solubility of the considered neuroactive drugs. To improve URB597 targeting to the brain, stealth nanoparticles were produced modifying the SLN surface with polysorbate 80. A behavioural study was conducted in rats to test the ability of SLN containing URB597 given by intranasal administration to alter behaviours relevant to psychiatric disorders. URB597 maintained its activity after nanoencapsulation, suggesting the possibility to propose this kind of vehicle as alternative to unphysiological mixtures usually employed for animal and clinical studies.

The February 2013 Food and Drug Administration (FDA) draft guidance for developing drugs for early-stage Alzheimer's disease (AD) creates certain challenges as they guide toward the use of one cognitive outcome to gain accelerated marketing approval for preclinical AD drugs, and a composite clinical scale - the Clinical Dementia Rating Scale in particular - for the primary outcome for prodromal AD clinical trials. In light of the developing knowledge regarding early stage diagnoses and clinical trials outcomes, we recommend that FDA describe its requirements for validating preclinical AD diagnoses for drug development purposes, maintain the principle for requiring coprimary outcomes, and encourage the advancement of outcomes for early stage AD trials. The principles for drug development for early stage AD should not differ from those for clinical AD, especially as the diagnoses of prodromal and early AD impinge on each other. The FDA should not recommend that a composite scale be used as a sole primary efficacy outcome to support a marketing claim unless it requires that the cognitive and functional components of such a scale are demonstrated to be individually meaningful. The current draft guidelines may inadvertently constrain efforts to better assess the clinical effects of new drugs and inhibit innovation in an area where evidence-based clinical research practices are still evolving.

Full Text Available According to the World Health Organization, one of the criteria for the standardized assessment of case causality in adverse drug reactions is the temporal relationship between the intake of a drug and the occurrence of a reaction or a laboratory test abnormality. This article presents and describes an algorithm for the detection of a reasonable temporal correlation between the administration of a drug and the alteration of a laboratory value course. The algorithm is designed to process normalized lab values and is therefore universally applicable. It has a sensitivity of 0.932 for the detection of lab value courses that show changes in temporal correlation with the administration of a drug and it has a specificity of 0.967 for the detection of lab value courses that show no changes. Therefore, the algorithm is appropriate to screen the data of electronic health records and to support human experts in revealing adverse drug reactions. A reference implementation in Python programming language is available.

A total of 103 drugs (including 14 combination drugs) were approved by the U.S. Food and Drug Administration from 2013 to 2016. Pharmacokinetic-based drug interaction profiles were analyzed using the University of Washington Drug Interaction Database and the clinical relevance of these observations was characterized based on information from New Drug Application reviews. CYP3A was identified as a major contributor to clinical drug-drug interactions (DDIs), involved in approximately 2/3 of all interactions. Transporters (alone or with enzymes) were found to participate in about half of all interactions, although most of these were weak-to-moderate interactions. When considered as victims, eight new molecular entities (NMEs; cobimetinib, ibrutnib, isavuconazole, ivabradine, naloxegol, paritaprevir, simeprevir, and venetoclax) were identified as sensitive substrates of CYP3A, two NMEs (pirfenidone and tasimelteon) were sensitive substrates of CYP1A2, one NME (dasabuvir) was a sensitive substrate of CYP2C8, one NME (eliglustat) was a sensitive substrate of CYP2D6, and one NME (grazoprevir) was a sensitive substrate of OATP1B1/3 (with changes in exposure greater than 5-fold when co-administered with a strong inhibitor). Interestingly, approximately 75% of identified CYP3A substrates were also substrates of P-gp. As perpetrators, most clinical DDIs involved weak-to-moderate inhibition or induction, with only two drugs (Viekira Pak and idelalisib) showing strong inhibition of CYP3A, and one NME (lumacaftor) considered as a strong CYP3A inducer. Among drugs with large changes in exposure (≥ 5-fold), whether as victim or perpetrator, the most represented therapeutic classes were antivirals and oncology drugs, suggesting a significant risk of clinical DDIs in these patient populations.

Comparison of buprenorphine and methadone effects on opiate self-administration in primates.
Mello, N K; Bree, M P; Mendelson, J H
1983-05-01
The effects of ascending and descending doses of buprenorphine (0.014-0.789 mg/kg/day) and methadone (0.179-11.86 mg/kg/day) on opiate and food intake were studied in Macaque monkeys over 195 to 245 days. Food (1-g banana pellets) and i.v. drug self-administration (heroin 0.01 or 0.02 mg/kg/injection or Dilaudid 0.02 mg/kg/injection) were maintained on a second-order schedule of reinforcement [FR 4 (VR 16:S)]. Buprenorphine (0.282-0.789 mg/kg/day) produced a significant suppression of opiate self-administration at 2.5 to 7 times the dose shown to be effective in human opiate abusers (P less than .05-.001). Methadone (1.43-11.86 mg/kg/day) did not suppress opiate self-administration in four of five monkeys across a dose range equivalent to 100 to 800 mg/day in man. The distribution of opiate self-administration across drug sessions did not account for the absence of methadone suppression as monkeys took 43% of the total daily opiate injections during the first daily drug session, 2.5 hr after methadone administration. During buprenorphine maintenance, food intake remained stable or increased significantly above base-line levels. Methadone maintenance was associated with significant decrements in food intake in four of five monkeys. Buprenorphine appeared to be significantly more effective in suppressing opiate self-administration than methadone across the dose range studied. Buprenorphine had none of the toxic side effects (seizures, respiratory depression, profound psychomotor retardation) associated with high doses of methadone over 6 to 8 months of daily drug treatment. These data are consistent with clinical studies of buprenorphine effects on heroin self-administration in human opiate addicts.

Design of a RESTful web information system for drug prescription and administration.
Bianchi, Lorenzo; Paganelli, Federica; Pettenati, Maria Chiara; Turchi, Stefano; Ciofi, Lucia; Iadanza, Ernesto; Giuli, Dino
2014-05-01
Drug prescription and administration processes strongly impact on the occurrence of risks in medical settings for they can be sources of adverse drug events (ADEs). A properly engineered use of information and communication technologies has proven to be a promising approach to reduce these risks. In this study, we propose PHARMA, a web information system which supports healthcare staff in the secure cooperative execution of drug prescription, transcription and registration tasks. PHARMA allows the easy sharing and management of documents containing drug-related information (i.e., drug prescriptions, medical reports, screening), which is often inconsistent and scattered across different information systems and heterogeneous organization domains (e.g., departments, other hospital facilities). PHARMA enables users to access such information in a consistent and secure way, through the adoption of REST and web-oriented design paradigms and protocols.

The history and contemporary challenges of the US Food and Drug Administration.
Borchers, Andrea T; Hagie, Frank; Keen, Carl L; Gershwin, M Eric
2007-01-01
The year 2006 marks the 100th anniversary of the regulatory agency now known as the US Food and Drug Administration (FDA), the first consumer protection agency of the federal government and arguably the most influential regulatory agency in the world. The FDA thus plays an integral role in the use of pharmaceuticals, not only in the United States but worldwide. The goal of this review was to present an overview of the FDA and place its current role in the perspectives of history and contemporary needs. Relevant materials for this review were identified through a search of the English-language literature indexed on MEDLINE (through 2006) using the main search terms United States Food and Drug Administration, FDA, history of the FDA, drug approvals, drug legislation, and FDA legislation. Results from the initial searches were then explored further. The statute that created the bureau which later became the FDA established this agency to prohibit interstate commerce of adulterated foods, drinks, and drugs. The Food, Drug, and Cosmetic Act that replaced it in 1938, and subsequent food and drug laws and amendments, expanded the FDA's responsibilities to cosmetics, medical devices, biological products, and radiation-emitting products. These amendments have also established the FDA as a mainly preventive regulatory agency that relies chiefly on pre-market control. As such, the FDA has played an important role in shaping the modern pharmaceutical industry by making the scientific approach and the clinical trial process the standard for establishing safety and efficacy and by making rigorous scientific analysis the predominant component of the process for pharmaceutical regulation. As shown in this review, the evolution of the FDA can be described as a series of "crisis-legislation-adaptation" cycles: a public health crisis promoted the passage of congressional legislation, which was then followed by implementation of the law by the FDA. However, the crises the FDA faces

The price elasticity of demand for prescription drugs is a crucial parameter of interest in designing pharmaceutical benefit plans. Estimating the elasticity using micro-data, however, is challenging because insurance coverage that includes deductibles, co-insurance provisions and maximum expenditure limits create a non-linear price schedule, making price endogenous (a function of drug consumption). In this paper we exploit an exogenous change in cost-sharing within the Quebec (Canada) public Pharmacare program to estimate the price elasticity of expenditure for drugs using IV methods. This approach corrects for the endogeneity of price and incorporates the concept of a 'rational' consumer who factors into consumption decisions the price they expect to face at the margin given their expected needs. The IV method is adapted from an approach developed in the public finance literature used to estimate income responses to changes in tax schedules. The instrument is based on the price an individual would face under the new cost-sharing policy if their consumption remained at the pre-policy level. Our preferred specification leads to expenditure elasticities that are in the low range of previous estimates (between -0.12 and -0.16). Naïve OLS estimates are between 1 and 4 times these magnitudes. (c) 2005 John Wiley & Sons, Ltd.

[Professional practice evaluation of injectable drug preparation and administration in neonatology].
Morin, P; Guillois, B; Gloanec, L; Chatelier, N; Saint-Lorant, G
2017-09-01
Adverse drug events are a daily concern in neonatology departments. The aim of this study was to assess the professional practices of preparation and administration of injectable forms of medications in neonatology. A professional practice evaluation with regard to the preparation and administration of various injectable forms of medications in different neonatology units within a given department was conducted by a pharmacy intern based on an assessment grid comprising ten criteria. Following an initial assessment, the results were presented to the care team, which validated the corrective measures put forward by a multiprofessional work group. A second assessment was conducted following the same methodology. Fifty of the department's 76 pediatric nurses were assessed during the first round of the audit and 21 during the second round. Two improvement priorities were identified: taking account of the dead volume of medication in needles and syringe hubs, together with complete identification of syringes used to administer medication. During the second round, these two aspects were improved, progressing from 38% to 100% and from 59% to 89%, respectively. To improve drug administration in neonatology and consequently, to improve patient safety, professional practice evaluation is an essential tool that requires close collaboration between the paramedical team, physicians and pharmacists. Its main value lies in the mobilization of the entire team around the subject in question, hence generating improved understanding and application of corrective measures.

The incentive sensitization theory of addiction posits that repeated exposure to drugs of abuse, like cocaine, can lead to long-term adaptations in the neural circuits that support motivated behavior, providing an account of pathological drug-seeking behavior. Although pre-clinical findings provide strong support for this theory, much remains unknown about the conditions that support incentive sensitization. The current study examined whether the mode of cocaine administration is an important factor governing that drug's long-term impact on behavior. Separate groups of rats were allowed either to self-administer intravenous cocaine or were given an equivalent number and distribution of unsignaled cocaine or saline infusions. During the subsequent test of incentive motivation (Pavlovian-to-instrumental transfer), we found that rats with a history of cocaine self-administration showed strong cue-evoked food seeking, in contrast to rats given unsignaled cocaine or saline. This finding indicates that the manner in which cocaine is administered can determine its lasting behavioral effects, suggesting that subjective experiences during drug use play a critical role in the addiction process. Our findings may therefore have important implications for the study and treatment of compulsive drug seeking. © 2013 Society for the Study of Addiction.

Drug combinations acting synergistically to kill cancer cells have become increasingly important in melanoma as an approach to manage the recurrent resistant disease. Protein kinase B (AKT) is a major target in this disease but its inhibitors are not effective clinically, which is a major concern. Targeting AKT in combination with WEE1 (mitotic inhibitor kinase) seems to have potential to make AKT-based therapeutics effective clinically. Since agents targeting AKT and WEE1 have been tested individually in the clinic, the quickest way to move the drug combination to patients would be to combine these agents sequentially, enabling the use of existing phase I clinical trial toxicity data. Therefore, a rapid preclinical approach is needed to evaluate whether simultaneous or sequential drug treatment has maximal therapeutic efficacy, which is based on a mechanistic rationale. To develop this approach, melanoma cell lines were treated with AKT inhibitor AZD5363 [4-amino- N -[(1 S )-1-(4-chlorophenyl)-3-hydroxypropyl]-1-(7 H -pyrrolo[2,3- d ]pyrimidin-4-yl)piperidine-4-carboxamide] and WEE1 inhibitor AZD1775 [2-allyl-1-(6-(2-hydroxypropan-2-yl)pyridin-2-yl)-6-((4-(4-methylpiperazin-1-yl)phenyl)amino)-1 H -pyrazolo[3,4- d ]pyrimidin-3(2 H )-one] using simultaneous and sequential dosing schedules. Simultaneous treatment synergistically reduced melanoma cell survival and tumor growth. In contrast, sequential treatment was antagonistic and had a minimal tumor inhibitory effect compared with individual agents. Mechanistically, simultaneous targeting of AKT and WEE1 enhanced deregulation of the cell cycle and DNA damage repair pathways by modulating transcription factors p53 and forkhead box M1, which was not observed with sequential treatment. Thus, this study identifies a rapid approach to assess the drug combinations with a mechanistic basis for selection, which suggests that combining AKT and WEE1 inhibitors is needed for maximal efficacy.

To develop a new minimal-stress model for intranasal administration in freely moving rats and to evaluate in this model the brain distribution of acetaminophen following intranasal versus intravenous administration. Male Wistar rats received one intranasal cannula, an intra-cerebral microdialysis probe, and two blood cannulas for drug administration and serial blood sampling respectively. To evaluate this novel model, the following experiments were conducted. 1) Evans Blue was administered to verify the selectivity of intranasal exposure. 2) During a 1 min infusion 10, 20, or 40 microl saline was administered intranasally or 250 microl intravenously. Corticosterone plasma concentrations over time were compared as biomarkers for stress. 3) 200 microg of the model drug acetaminophen was given in identical setup and plasma, and brain pharmacokinetics were determined. In 96% of the rats, only the targeted nasal cavity was deeply colored. Corticosterone plasma concentrations were not influenced, neither by route nor volume of administration. Pharmacokinetics of acetaminophen were identical after intravenous and intranasal administration, although the Cmax in microdialysates was reached a little earlier following intravenous administration. A new minimal-stress model for intranasal administration in freely moving rats has been successfully developed and allows direct comparison with intravenous administration.

Drug-induced akinesia is a potential cause of pressure ulcers. However, pressure ulcers that are caused by drug-induced akinesia are not considered an adverse drug reaction (ADR). We propose that drug-induced pressure ulcers (DIPU) are pressure ulcers that are caused by an external force that is experienced after drug administration, and we considered resolution of these ulcers after drug discontinuation to be a supportive finding. In this report, we reviewed the medical records of pressure ulcer cases from a 300-bed hospital. Among 148 patients, four patients with pressure ulcers met the criterion for DIPU. In these cases, the suspected DIPU were related to treatment with olanzapine, fluvoxamine, valproic acid, clotiazepam, triazolam and rilmazafone. These drugs were administrated to manage the patients' behavioral and psychological symptoms that accompanied dementia. The DIPU in these patients were categorized as stage IV according to the National Pressure Ulcer Advisory Panel criteria. Discontinuation of the causal drugs led to significant improvements or complete healing of the pressure ulcers, and the patients subsequently recovered their mobility. Therefore, we propose that DIPU are potential ADR that have been overlooked in clinical practice. Thus, recognition of DIPU as an ADR may be important in preventing and appropriately managing pressure ulcers among elderly patients. © 2015 Japanese Dermatological Association.

Subregional hypoxia is a common feature of tumors and is recognized as a limiting factor for the success of radiotherapy and chemotherapy. TH-302, a hypoxia-activated prodrug selectively targeting hypoxic regions of solid tumors, delivers a cytotoxic warhead to the tumor, while maintaining relatively low systemic toxicity. The antitumor activity, different dosing sequences, and dosing regimens of TH-302 in combination with commonly used conventional chemotherapeutics were investigated in human tumor xenograft models. Seven chemotherapeutic drugs (docetaxel, cisplatin, pemetrexed, irinotecan, doxorubicin, gemcitabine, and temozolomide) were tested in combination with TH-302 in eleven human xenograft models, including non-small cell lung cancer (NSCLC), colon cancer, prostate cancer, fibrosarcoma, melanoma, and pancreatic cancer. The antitumor activity of docetaxel, cisplatin, pemetrexed, irinotecan, doxorubicin, gemcitabine, and temozolomide was increased when combined with TH-302 in nine out of eleven models tested. Administration of TH-302 2-8 h prior to the other chemotherapeutics yielded superior efficacy versus other sequences tested. Simultaneous administration of TH-302 and chemotherapeutics increased toxicity versus schedules with dosing separations. In a dosing optimization study, TH-302 administered daily at 50 mg/kg intraperitoneally for 5 days per week in the H460 NSCLC model showed the optimal response with minimal toxicity. TH-302 enhances the activity of a wide range of conventional anti-neoplastic agents in a broad panel of in vivo xenograft models. These data highlight in vivo effects of schedule and order of drug administration in regimen efficacy and toxicity and have relevance to the design of human regimens incorporating TH-302.

Investigation of the mechanisms of action behind Electromotive Drug Administration (EMDA).
Kos, Bor; Vásquez, Juan Luis; Miklavčič, Damijan; Hermann, Gregers G G; Gehl, Julie
2016-01-01
Bladder cancer is a cause of considerable morbidity worldwide. Electromotive Drug Administration is a method that combines intravesical chemotherapy with local electric field application. Electroporation has been suggested among other mechanisms as having a possible role in the therapy, so the goal of the present study was to investigate the electric fields present in the bladder wall during the treatment to determine which mechanisms might be involved. Electromotive Drug Administration involves applying intravesical mitomycin C with direct current of 20 mA delivered through a catheter electrode for 30 min. For numerical electric field computation we built a 3-D nonhomogeneous patient specific model based on CT images and used finite element method simulations to determine the electric fields in the whole body. Results indicate that highest electric field in the bladder wall was 37.7 V/m. The mean electric field magnitude in the bladder wall was 3.03 V/m. The mean magnitude of the current density in the bladder wall was 0.61 A/m(2). The present study shows that electroporation is not the mechanism of action in EMDA. A more likely explanation of the mechanism of action is iontophoretic forces increasing the mitomycin C concentration in the bladder wall.

Celecoxib, an inhibitor of cyclooxygenase-2, is being investigated for enhancement of chemotherapy efficacy in cancer clinical trials. This study investigates the ability of cyclooxygenase-2 inhibitors to sensitize cells from different origins to several chemotherapeutic agents. The effect of the drug's mechanism of action and sequence of administration are also investigated. The sensitivity, cell cycle, apoptosis and DNA damage of five different cancer cell lines (HeLa, HCT116, HepG2, MCF7 and U251) to 5-FU, cisplatin, doxorubicin and etoposide ± celecoxib following different incubation schedules were analyzed. We found antagonism between celecoxib and the four drugs in the breast cancer cells MCF7 following all incubation schedules and between celecoxib and doxorubicin in all cell lines except for two combinations in HCT116 cells. Celecoxib with the other three drugs in the remaining four cell lines resulted in variable interactions. Mechanistic investigations revealed that celecoxib exerts different molecular effects in different cells. In some lines, it abrogates the drug-induced G2/M arrest enhancing pre-mature entry into mitosis with damaged DNA thus increasing apoptosis and resulting in synergism. In other cells, it enhances drug-induced G2/M arrest allowing time to repair drug-induced DNA damage before entry into mitosis and decreasing cell death resulting in antagonism. In some synergistic combinations, celecoxib-induced abrogation of G2/M arrest was not associated with apoptosis but permanent arrest in G1 phase. These results, if confirmed in-vivo, indicate that celecoxib is not a suitable chemosensitizer for breast cancer or with doxorubicin for other cancers. Moreover, combination of celecoxib with other drugs should be tailored to the tumor type, drug and administration schedule. - Graphical abstract: Display Omitted Highlights: → Celecoxib may enhance effects of anticancer drugs. → Its combination with four drugs was tested in five cancer cell

Dextromethorphan: a case study on addressing abuse of a safe and effective drug.
Spangler, David C; Loyd, Catherine M; Skor, Emily E
2016-06-23
Dextromethorphan is a safe, effective cough suppressant, available without a prescription in the United States since 1958. Due to a perceived prevalence of abuse of dextromethorphan by teens, in 2007 the Drug Enforcement Administration requested the Food and Drug Administration evaluate whether dextromethorphan should be recommended for scheduling under the Controlled Substances Act. The Food and Drug Administration held an Advisory Committee meeting in 2010 to provide a scientific and medical evaluation of dextromethorphan and its abuse potential. To address reports of abuse, particularly by teens in the United States, the Consumer Healthcare Products Association initiated an abuse mitigation plan in 2010 with specific goals related to awareness of the behavior, perception of risk, social disapproval, and access to the products. In identifying abuse interventions, experts acknowledge that substance abuse among teens is a highly complex behavior and indicate that the best course of action is to address prevention by focusing on the factors that impact teen behavior. It is noteworthy that the annual prevalence of over-the-counter cough medicine abuse has sharply decreased since 2010. While a true cause-and-effect relationship cannot be assured, the Consumer Healthcare Products Association and its member companies believe that the increased awareness of the issue since the 2010 Food and Drug Administration Advisory Committee meeting, and the subsequent implementation of a well-delivered and targeted abuse mitigation plan that addressed the levers influencing teen decisions is contributing to the observed reduction in abuse. During the period of 2010-2015, reported abuse of dextromethorphan by 8(th), 10(th), and 12(th) graders decreased 35 %. The authors believe this reduction supports the view of the Consumer Healthcare Products Association at the outset of the abuse mitigation plan effort and today: Controlled substance scheduling or prescription requirements would

The aseptic techniques of anesthesiologists in the preparation and administration of injected medications have not been extensively investigated, but emerging data demonstrate that inadvertent lapses in aseptic technique may be an important contributor to surgical site and other postoperative infections. A prospective, open, microbiological audit of 303 cases in which anesthesiologists were asked to inject all bolus drugs, except propofol and antibiotics, through a 0.2-µm filter was performed. The authors cultured microorganisms, if present, from the 0.2-µm filter unit and from the residual contents of the syringes used for drawing up or administering drugs. Participating anesthesiologists rated ease of use of the filters after each case. Twenty-three anesthesiologists each anesthetized up to 25 adult patients. The authors isolated microorganisms from filter units in 19 (6.3%) of 300 cases (3 cases were excluded), including Staphylococcus capitis, Staphylococcus warneri, Staphylococcus epidermidis, Staphylococcus haemolyticus, Micrococcus luteus/lylae, Corynebacterium, and Bacillus species. The authors collected used syringes at the end of each case and grew microorganisms from residual drug in 55 of these 2,318 (2.4%) syringes including all the aforementioned microorganisms and also Kocuria kristinae, Staphylococcus aureus, and Staphylococcus hominus. Participants' average rating of ease of use of the filter units was 3.5 out of 10 (0 being very easy and 10 being very difficult). Microorganisms with the potential to cause infection are being injected (presumably inadvertently) into some patients during the administration of intravenous drugs by bolus during anesthesia. The relevance of this finding to postoperative infections warrants further investigation.

To achieve well-being in patients in Palliative Care is required to know which are the most common symptoms, which are the drugs used for relief, which are the routes of administration of drugs that are suitable, how effective the drugs are and what incompatibilities, interactions and adverse effects occur. The aim of this article is to review the relevant issues in the management of the drugs commonly used by nursing in Palliative Care and presenting recommendations to clinical practice. Management interventions drugs for nurses in Palliative Care recommended by the scientific literature after a search of Scopus, CINAHL, Medline, PubMed, UpToDate and Google Scholar are selected. The oral route is the choice for patients in palliative situation and subcutaneous route when the first is not available. The symptoms, complex, intense and moody, should be systematically reevaluated by the nurse, to predict when a possible decompensation of it needing extra dose of medication. Nurses must be able to recognize the imbalance of well-being and act quickly and effectively, to get relief to some unpleasant situations for the patient as the pain symptoms, dyspnea or delirium.

Full Text Available BACKGROUND: In most countries of Sub-Saharan Africa, control of lymphatic filariasis (LF is based on annual mass drug administration (MDA with a combination of ivermectin and albendazole. Treatment coverages are however often suboptimal for programmes to reach the goal of transmission interruption within reasonable time. The present study aimed to identify predictors and barriers to individual drug uptake during MDA implementation by the National LF Elimination Programme in Tanzania. METHODS: A questionnaire based cross sectional household survey was carried out in two rural and two urban districts in Lindi and Morogoro regions shortly after the 2011 MDA. 3279 adults (≥15 years were interviewed about personal characteristics, socio-economic status, MDA drug uptake among themselves and their children, reasons for taking/not taking drugs, and participation in previous MDA activities for LF control. FINDINGS: The overall drug uptake rate was 55.1% (range of 44.5-75.6% between districts. There was no overall major difference between children (54.8% and adults (55.2% or between females (54.9% and males (55.8%, but the role of these and other predictors varied to some extent between study sites. Major overall predictors of drug uptake among the interviewed adults were increasing age and history of previous drug uptake. Being absent from home during drug distribution was the main reason for not taking the drugs (50.2% followed by clinical contraindications to treatment (10.8%, missing household visits of drug distributors (10.6%, and households not being informed about the distribution (9.0%. CONCLUSION: Drug uptake relied more on easily modifiable provider-related factors than on individual perceptions and practices in the target population. Limited investments in appropriate timing, dissemination of accurate timing information to recipients and motivation of drug distributors to visit all households (repeatedly when residents are absent are likely

Clinical trial enrichment involves prospectively incorporating trial design elements that increase the probability of detecting a treatment effect. The use of enrichment strategies in pediatric drug development has not been systematically assessed. We analyzed the use of enrichment strategies in pediatric trials submitted to the US Food and Drug Administration from 2012-2016. In all, 112 efficacy studies associated with 76 drug development programs were assessed and their overall success rates were 78% and 75%, respectively. Eighty-eight trials (76.8%) employed at least one enrichment strategy; of these, 66.3% employed multiple enrichment strategies. The highest trial success rates were achieved when all three enrichment strategies (practical, predictive, and prognostic) were used together within a single trial (87.5%), while the lowest success rate was observed when no enrichment strategy was used (65.4%). The use of enrichment strategies in pediatric trials was found to be associated with trial and program success in our analysis. © 2017 American Society for Clinical Pharmacology and Therapeutics.

Cannabinoids are the bioactive components of the Cannabis plant that display a diverse range of therapeutic qualities. We explored the activity of six cannabinoids, used both alone and in combination in leukaemic cells. Cannabinoids were cytostatic and caused a simultaneous arrest at all phases of the cell cycle. Re-culturing pre-treated cells in drug-free medium resulted in dramatic reductions in cell viability. Furthermore, combining cannabinoids was not antagonistic. We suggest that the activities of some cannabinoids are influenced by treatment schedules; therefore, it is important to carefully select the most appropriate strategy in order to maximise their efficacy.

Effect of sampling schedule on pharmacokinetic parameter estimates of promethazine in astronauts
Boyd, Jason L.; Wang, Zuwei; Putcha, Lakshmi
2005-08-01
Six astronauts on the Shuttle Transport System (STS) participated in an investigation on the pharmacokinetics of promethazine (PMZ), a medication used for the treatment of space motion sickness (SMS) during flight. Each crewmember completed the protocol once during flight and repeated thirty days after returned to Earth. Saliva samples were collected at scheduled times for 72 h after PMZ administration; more frequent samples were collected on the ground than during flight owing to schedule constraints in flight. PMZ concentrations in saliva were determined by a liquid chromatographic/mass spectrometric (LC-MS) assay and pharmacokinetic parameters (PKPs) were calculated using actual flight and ground-based data sets and using time-matched sampling schedule on ground to that during flight. Volume of distribution (Vc) and clearance (Cls) decreased during flight compared to that from time-matched ground data set; however, ClS and Vc estimates were higher for all subjects when partial ground data sets were used for analysis. Area under the curve (AUC) normalized with administered dose was similar in flight and partial ground data; however AUC was significantly lower using time-matched sampling compared with the full data set on ground. Half life (t1/2) was longest during flight, shorter with matched-sampling schedule on ground and shortest when complete data set from ground was used. Maximum concentration (Cmax), time for Cmax (tmax), parameters of drug absorption, depicted a similar trend with lowest and longest respectively, during flight, lower with time- matched ground data and highest and shortest with full ground data.

Amphetamine increases schedule-induced drinking reduced by negative punishment procedures.
Pérez-Padilla, Angeles; Pellón, Ricardo
2003-05-01
d-Amphetamine has been reported to increase schedule-induced drinking punished by lick-dependent signalled delays in food delivery. This might reflect a drug-behaviour interaction dependent on the type of punisher, because no such effect has been found when drinking was reduced by lick-contingent electric shocks. However, the anti-punishment effect of amphetamine could be mediated by other behavioural processes, such as a loss of discriminative control or an increase in the value of delayed reinforcers. To test the effects of d-amphetamine on the acquisition and maintenance of schedule-induced drinking reduced by unsignalled delays in food delivery. Rats received 10-s unsignalled delays initiated by each lick after polydipsia was induced by a fixed-time 30-s food reinforcement schedule or from the outset of the experiment. Yoked-control rats received these same delays but independently of their own behaviour. d-Amphetamine (0.1-3.0 mg/kg) was then tested IP. d-Amphetamine dose-dependently increased and then decreased punished schedule-induced drinking. The drug led to dose-dependent reductions when the delays were not contingent or when they were applied from the outset of training. These results support the contention that d-amphetamine has an increasing effect on schedule-induced drinking that has been previously reduced by a negative punishment procedure. This effect cannot be attributed to other potentially involved processes, and therefore support the idea that drug effects on punished behaviour depend on punishment being delays in food or shock deliveries.

P-Glycoprotein (P-gp) mediated efflux is recognized as a significant biochemical barrier affecting oral absorption for a number of drugs. Various conflicting reports have been published regarding the effects of grapefruit juice (GFJ) on P-gp-mediated drug efflux, in which GFJ has been shown both to inhibit and activate it. Hence, the present study adopted a two-way approach, involving both co-treatment and chronic administration. Bi-directional transport of paclitaxel (PCL) was carried out in the absence and presence of GFJ extract, in rat everted ileum sac. Further, the effect of chronic administration of GFJ to rats was characterized by permeability studies with indinavir (INDI). Co-treatment of GFJ extract at 100% concentration reduced the asymmetric transport of PCL (efflux ratio = 20.8) by increasing absorptive (A --> B) transport by 921% and reducing secretory (B --> A) transport by 41%. Further, GFJ showed a concentration dependent effect on PCL permeability. Imipramine, a passive permeability marker with absorptive permeability of 15.33 +/- 4.26 x 10(-6) cm/s showed no asymmetric transport and also no significant (P extract inhibited P-gp-mediated efflux in co-treatment, whereas chronic administration led to increased levels of P-gp expression, thus having a profound effect on intestinal absorption and GFJ-drug interactions in vivo.

Magnetic nanoparticles have been investigated for biomedical applications for more than 30 years. The development of biocompatible nanosized drug delivery systems for specific targeting of therapeutics is imminent in medical research, especially for treating cancer and vascular diseases. We used drug-labeled magnetic iron oxide nanoparticles, which were attracted to an experimental tumor in rabbits with an external magnetic field (magnetic drug targeting, MDT). Aim of this study was to detect and quantify the biodistribution of the magnetic nanoparticles by magnetorelaxometry. The study shows higher amount of nanoparticles in the tumor after intraarterial application and MDT compared to intravenous administration.

the interval between induction of anesthesia and surgery start time will help decrease patient exposure to inhalational agents. While the Food and Drug Administration warning was based on duration and repetitive nature of exposure rather than concentration of inhalational agents, intravenous tocolytics can be considered for intraoperative use, to provide uterine relaxation for fetal surgery, in lieu of high concentrations of inhalational anesthetic agents. Practitioners should consider the type of anesthesia that will be administered and the potential risks when scheduling patients for nonobstetric and fetal surgery. Copyright © 2017 Elsevier Inc.

This study aimed to examine the applicability of polyethyleneimine (PEI)-modified magnetic nanoparticles (GPEI) as a potential vascular drug/gene carrier to brain tumors. In vitro, GPEI exhibited high cell association and low cell toxicity--properties which are highly desirable for intracellular drug/gene delivery. In addition, a high saturation magnetization of 93 emu/g Fe was expected to facilitate magnetic targeting of GPEI to brain tumor lesions. However, following intravenous administration, GPEI could not be magnetically accumulated in tumors of rats harboring orthotopic 9L-gliosarcomas due to its poor pharmacokinetic properties, reflected by a negligibly low plasma AUC of 12 +/- 3 microg Fe/ml min. To improve "passive" GPEI presentation to brain tumor vasculature for subsequent "active" magnetic capture, we examined the intra-carotid route as an alternative for nanoparticle administration. Intra-carotid administration in conjunction with magnetic targeting resulted in 30-fold (p=0.002) increase in tumor entrapment of GPEI compared to that seen with intravenous administration. In addition, magnetic accumulation of cationic GPEI (zeta-potential = + 37.2 mV) in tumor lesions was 5.2-fold higher (p=0.004) than that achieved with slightly anionic G100 (zeta-potential= -12 mV) following intra-carotid administration, while no significant accumulation difference was detected between the two types of nanoparticles in the contra-lateral brain (p=0.187). These promising results warrant further investigation of GPEI as a potential cell-permeable, magnetically-responsive platform for brain tumor delivery of drugs and genes. 2010 Elsevier Ltd.

Microcomputer-based workforce scheduling for hospital porters.
Lin, C K
1999-01-01
This paper focuses on labour scheduling for hospital porters who are the major workforce providing routine cleansing of wards, transportation and messenger services. Generating an equitable monthly roster for porters while meeting the daily minimum demand is a tedious task scheduled manually by a supervisor. In considering a variety of constraints and goals, a manual schedule was usually produced in seven to ten days. To be in line with the strategic goal of scientific management of an acute care regional hospital in Hong Kong, a microcomputer-based algorithm was developed to schedule the monthly roster. The algorithm, coded in Digital Visual Fortran 5.0 Professional, could generate a monthly roster in seconds. Implementation has been carried out since September 1998 and the results proved to be useful to hospital administrators and porters. This paper discusses both the technical and human issues involved during the computerization process.

Wallace, Laurel-Anne; Pierson, Sharon
2008-01-01
In 2003, Hamilton Health Sciences embarked on an initiative to improve and standardize nursing schedules and scheduling practices. The scheduling project was one of several initiatives undertaken by a corporate-wide Nursing Resource Group established to enhance the work environment and patient care and to ensure appropriate utilization of nursing resources across the organization's five hospitals. This article focuses on major activities undertaken in the scheduling initiative. The step-by-step approach described, plus examples of the scheduling resources developed and samples of extended-tour schedules, will all provide insight, potential strategies and practical help for nursing administrators, human resources (HR) personnel and others interested in improving nurse scheduling.

A 59-year-old female with diffuse large B-cell lymphoma was treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) regimen. In addition, we administered pegfilgrastim for treating chemotherapy-induced febrile neutropenia. She complained of fever and neck and chest pain a few days after pegfilgrastim administration during the third and fourth courses of R-CHOP. Radiological imaging revealed an inflammation of large vessels, which led to the diagnosis of drug-associated vasculitis. We confirmed that vasculitis observed in this case was caused by pegfilgrastim administration because similar symptoms appeared with both injections of pegfilgrastim.

Evidence suggests that responsiveness to a drug-paired cue is predicted by the reinforcing magnitude of the drug during prior self-administration. It remains unclear, however, if this principle holds true when comparisons are made across drug reinforcers. The current study was therefore devised to test the hypothesis that differences in the animals' responsiveness to a cocaine- or heroin-paired cue presented during extinction would reflect differences in the patterns of prior cocaine and heroin runway self-administration. Rats ran a straight alley for single intravenous injections of either heroin (0.1 mg/kg/inj) or cocaine (1.0 mg/kg/inj) each paired with a distinct olfactory cue. Animals experienced 15 trials with each drug reinforcer in a counterbalanced manner. Start latencies, run times, and retreat behaviors (a form of approach-avoidance conflict) provided behavioral indices of the subjects' motivation to seek the reinforcer on each trial. Responsiveness to each drug-paired cue was assessed after 7, 14, or 21 days of non-reinforced extinction trials. Other animals underwent conditioned place preference (CPP) testing to ensure that the two drug reinforcers were capable of producing drug-cue associations. While both drugs produced comparable CPPs, heroin served as a stronger incentive stimulus in the runway as evidenced by faster start and run times and fewer retreats. In contrast, cocaine- but not heroin-paired cues produced increases in drug-seeking behavior during subsequent extinction trials. The subjects' responsiveness to drug-paired cues during extinction was not predicted by differences in the motivation to seek heroin versus cocaine during prior drug self-administration.

Establishment of a New Drug Code for Marihuana Extract. Final rule.
2016-12-14
The Drug Enforcement Administration is creating a new Administration Controlled Substances Code Number for "Marihuana Extract." This code number will allow DEA and DEA-registered entities to track quantities of this material separately from quantities of marihuana. This, in turn, will aid in complying with relevant treaty provisions. Under international drug control treaties administered by the United Nations, some differences exist between the regulatory controls pertaining to marihuana extract versus those for marihuana and tetrahydrocannabinols. The DEA has previously established separate code numbers for marihuana and for tetrahydrocannabinols, but not for marihuana extract. To better track these materials and comply with treaty provisions, DEA is creating a separate code number for marihuana extract with the following definition: "Meaning an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant." Extracts of marihuana will continue to be treated as Schedule I controlled substances.

Matching Judicial Supervision to Clients’ Risk Status in Drug Court
Marlowe, Douglas B.; Festinger, David S.; Lee, Patricia A.; Dugosh, Karen L.; Benasutti, Kathleen M.
2007-01-01
This article reports outcomes from a program of experimental research evaluating the risk principle in drug courts. Prior studies revealed that participants who were high risk and had (a) antisocial personality disorder or (b) a prior history of drug abuse treatment performed better in drug court when scheduled to attend biweekly judicial status hearings in court. In contrast, participants who were low risk performed equivalently regardless of the court hearings schedule. This study prospectively matches drug court clients to the optimal schedule of court hearings based on an assessment of their risk status and compares outcomes to clients randomly assigned to the standard hearings schedule. Results confirmed that participants who were high risk and matched to biweekly hearings had better during-treatment outcomes than participants assigned to status hearings as usual. These findings provide confirmation of the risk principle in drug courts and yield practical information for enhancing the efficacy and cost-efficiency of drug courts. PMID:18174915

1982-01-01
The Food and Drug Administration is a scientific regulatory agency whose consumer protection activities cover a wide range of products including foods and additives, and pesticide residues on foods; drugs; cosmetics; medical devices; and radiation-emitting electronic products. Amongst its concerns is the possible teratogen effects of regulated products to which the pregnant woman is exposed. The policies and programs of the agency directed toward reducing such risks to the unborn are reviewed. These measures include guidelines for animal reproduction studies and for clinical trials involving women to childbearing potential; labeling of products to disclose known or possible harm to the fetus or embryo; surveillance procedures designed to detect previously unsuspected adverse effects of marketed products; research activities designed to develop better understanding of developmental toxicology and improved techniques for detecting embryocidal and embryotoxic effects; and educational efforts directed both to professionals and the public regarding hazards to the unborn of agency-regulated products

To report 2 cases of corneal perforation associated with the use of oral nonsteroidal anti-inflammatory drugs (NSAIDs). In a 62-year-old woman and a 79-year-old woman, corneal perforation occurred after 7 days and 5 months of oral NSAIDs administration, respectively. After NSAIDs were discontinued, the cornea epithelialized and the anterior chamber formed within 14 and 10 days, respectively. It is well known that topical NSAIDs cause corneal perforation. Observations in the present cases suggest that the oral administration of NSAIDs may also cause corneal damage, and hence, medical professionals should consider the risk of damage to the cornea when administering these drugs orally.

The intranasal route of administration has proven to be an effective method for bypassing the blood brain barrier and avoiding first pass hepatic metabolism when targeting drugs to the brain. Most small molecules gain rapid access to CNS parenchyma when administered intranasally. However, bioavailability is affected by various factors ranging from the molecular weight of the drug to the mode of intranasal delivery. We examined the effects of animal posture, intranasal application method and animal weight and age on the delivery of radiolabeled pralidoxime ( 3 H-2-PAM) to the brain of rats. We found that using upright vs. supine posture did not significantly affect 3 H-2-PAM concentrations in different brain regions. Older animals with higher weights required increased doses to achieve the same drug concentration throughout the brain when compared to young animals with lower body weights. The use of an intranasal aerosol propelled delivery device mainly increased bioavailability in the olfactory bulbs, but did not reliably increase delivery of the drug to various other brain regions, and in some regions of the brain delivered less of the drug than simple pipette administration. In view of the emerging interest in the use of intranasal delivery of drugs to combat cognitive decline in old age, we tested effectiveness in very old rats and found the method to be as effective in the older rats.

Schedule-dependent interaction of paclitaxel (taxol[reg]) and irradiation in vitro
International Nuclear Information System (INIS)
Plasswilm, Ludwig; Cordes, Nils
1996-01-01
Purpose/Objective: The optimal dose and schedule of paclitaxel in combination with irradiation has not been determined yet. The aim of our study was first to compare the in vitro cytotoxicity and enhancement of radiation sensitization as a function of single dose versus fractionated paclitaxel administration. Secondly the cytotoxicity of the solvent cremophor/ethanol alone was evaluated and compared to the effect of Taxol[reg]. Materials and Methods: A fibroblast cell line (B14) in exponential growth phase with a doubling time of approximately 12 hours was used. Untreated cells and cells treated with phosphate buffered saline (PBS) were plated and used as control. Single dose and fractionated irradiation of 0 to 20 Gy (2.2 Gy/min) was delivered to the cells. Cytotoxicity of Taxol[reg] was examined at concentrations varied from 2 to 50 nmol compared to aliquots of cremophor/ethanol. Single dose (1x10 nmol) versus fractionated (2 nmol/day, day 1 to day 5) administration of Taxol[reg] was investigated. The combination of Taxol[reg] plus irradiation as single dose and fractionated administration was accomplished with 10 nmol Taxol[reg] on day 1 plus 10 Gy irradiation on day 1 (single dose administration) versus Taxol[reg], 2 nmol/day, day 1 to day 5, plus irradiation, 2 Gy/day, day 1 to day 5 (fractionated administration). Taxol[reg] administration was always performed for a 3 hour period with a 1-hour and 9-hour interval between Taxol[reg] administration and irradiation. All experiments were repeated in the same schedule with single dose and fractional administration of cremophor/ethanol. The clonogenic assay was applied to determine cell survival. Flow cytometric measurements were performed to study cell cycle DNA distribution. Results: Untreated controls and PBS treated cells (single dose and fractionated schedule) demonstrate an average plating efficiency of 93%. Single dose Taxol[reg] (1x10 nmol) administration show an average clonogenic survival of 88% (cremophor

Combination chemotherapy is commonly used to treat late stage cancer; however, treatment is often limited by systemic toxicity. Optimizing drug ratio and schedule can improve drug combination activity and reduce dose to lower toxicity. Here, we identify gemcitabine (GEM) and doxorubicin (DOX) as a synergistic drug pair in vitro for the triple negative breast cancer cell line MDA-MB-231. Drug synergy and caspase activity were increased the most by exposing cells to GEM prior to DOX in vitro. While the combination was more effective than the single drugs at inhibiting MDA-MB-231 growth in vivo, the clear schedule dependence observed in vitro was not observed in vivo. Differences in drug exposure and cellular behavior in vivo compared to in vitro are likely responsible. This study emphasizes the importance in understanding how schedule impacts drug synergy and the need to develop more advanced strategies to translate synergy to the clinic.

A stochastic model for the probability of malaria extinction by mass drug administration.
Pemberton-Ross, Peter; Chitnis, Nakul; Pothin, Emilie; Smith, Thomas A
2017-09-18
Mass drug administration (MDA) has been proposed as an intervention to achieve local extinction of malaria. Although its effect on the reproduction number is short lived, extinction may subsequently occur in a small population due to stochastic fluctuations. This paper examines how the probability of stochastic extinction depends on population size, MDA coverage and the reproduction number under control, R c . A simple compartmental model is developed which is used to compute the probability of extinction using probability generating functions. The expected time to extinction in small populations after MDA for various scenarios in this model is calculated analytically. The results indicate that mass drug administration (Firstly, R c must be sustained at R c 95% to have a non-negligible probability of successful elimination. Stochastic fluctuations only significantly affect the probability of extinction in populations of about 1000 individuals or less. The expected time to extinction via stochastic fluctuation is less than 10 years only in populations less than about 150 individuals. Clustering of secondary infections and of MDA distribution both contribute positively to the potential probability of success, indicating that MDA would most effectively be administered at the household level. There are very limited circumstances in which MDA will lead to local malaria elimination with a substantial probability.

Previous studies have shown that both pemetrexed, a cytotoxic drug, and erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), inhibit the cell growth of pancreatic cancer cells. However, whether they exert a synergistic antitumor effect on pancreatic cancer cells remains unknown. The present study aimed to assess the synergistic effect of erlotinib in combination with pemetrexed using different sequential administration schedules on the proliferation of human pancreatic cancer BXPC-3 and PANC-1 cells and to probe its cellular mechanism. The EGFR and K-ras gene mutation status was examined by quantitative PCR high-resolution melting (qPCR-HRM) analysis. BXPC-3 and PANC-1 cells were incubated with pemetrexed and erlotinib using different administration schedules. MTT assay was used to determine cytotoxicity, and cell cycle distribution was determined by flow cytometry. The expression and phosphorylation of EGFR, HER3, AKT and MET were determined using Western blotting. Both pemetrexed and erlotinib inhibited the proliferation of BXPC-3 and PANC-1 cells in a dose- and time-dependent manner in vitro. Synergistic effects on cell proliferation were observed when pemetrexed was used in combination with erlotinib. The degree of the synergistic effects depended on the administration sequence, which was most obvious when erlotinib was sequentially administered at 24-h interval following pemetrexed. Cell cycle studies revealed that pemetrexed induced S arrest and erlotinib induced G(0)/G(1) arrest. The sequential administration of erlotinib following pemetrexed induced S arrest. Western blot analyses showed that pemetrexed increased and erlotinib decreased the phosphorylation of EGFR, HER3 and AKT, respectively. However, both pemetrexed and erlotinib exerted no significant effects on the phosphorylation of c-MET. The phosphorylation of EGFR, HER3 and AKT was significantly suppressed by scheduled incubation with pemetrexed followed by erlotinib

Significant clinical success of colon targeted dosage forms has been limited by their inappropriate release profile at the target site. Their failure to release the drug completely in the colon may be attributed to changes in the colonic milieu because of pathological state, drug effect and psychological stress accompanying the diseased state or, a combination of these. Alteration in normal colonic pH and bacterial picture leads to incomplete release of drug from the designed delivery system. We report the effectiveness of a targeted delivery system wherein the constant replenishment of the colonic microbiota is achieved by concomitant administration of probiotics along with the polysaccharide based drug delivery system. Guar gum coated spheroids of sulfasalazine were prepared. In the dissolution studies, these spheroids showed markedly higher release in the simulated colonic fluid. In vivo experiments conducted in rats clearly demonstrated the therapeutic advantage of co-administration of probiotics with guar gum coated spheroids. Our results suggest that concomitant use of probiotics along with the polysaccharide based delivery systems can be a simple strategy to achieve satisfactory colon targeting of drugs.

The authors have recently demonstrated that a combined administration of dipyridamole and adenosine monophosphate to mice induces radioprotective effects in terms of postirradiation hematopoietic recovery in animals irradiated with a single dose. The aim of the present experiments was to investigate the radioprotective ability of the drug combination under conditions of fractionated radiation. It was shown that administration of the drugs either 15 or 60 min before each of the five daily 3-Gy doses of gamma radiation enhances hematopoietic recovery and survival of mice exposed to an additional 'top-up' dose of 3.5 Gy. Furthermore, it was ascertained that administration of the drugs 60 min prior to irradiation is more effective than administration of the drugs 15 min prior to irradiation. Due to the evidence that administration of the drugs 15 min prior to irradiation protects the organism mainly via mechanisms of systemic hypoxia while the pretreatment 60 min before irradiation avoids the role of hypoxia and mainly induces cell proliferation effects, the present results suggest a more protective role of mechanisms stimulating hematopoiesis under conditions of fractionated radiation. The data may provide a basis for more rational use of radioprotection in fractionated radiation techniques. (author) 1 tab., 1 fig., 25 refs

Drug adherence is central to the treatment of dementia, which might reduce compliance due to memory loss, particularly among home-based patients with dementia. In order to improve drug adherence, we suggest the efficient and effective supervised administration by use of information communication technology(ICT). ICT makes face-to-face real-time communication possible, and it also enables picture sharing. Therefore, it might be useful to apply ICT to controlling and supervising medication for patients with dementia to improve drug adherence. Accordingly, we enrolled patients who were supposed to take a newly prescribed anti-dementia patch containing the choline esterase inhibitor rivastigmine(Rivastach®)and investigated the effect of ICT-based intervention for drug adherence, emotional change, and cognitive change, utilizing Skype, a free communication software program. Scheduled Skype interventions increased drug adherence ratio, levels of subjective satisfaction, and instrumental activities of daily living(IADL). Furthermore, we can provide patients and their caregivers with a feeling of safety through regular bidirectional communication, as patients can easily consult medical staff regarding the adverse effects of newly prescribed drugs. Instead of frequent visits to their primary physicians, ICT-based communications can be used as a substitute for supervision of medication, given the availability of the telecommunication system. By directly connecting the medical institution to the home, we expect that this ICT-based system will expand into the geriatric care field, including the care of elderly individuals living alone.

This article documents understandings and responses to mass drug administration (MDA) for the treatment and prevention of lymphatic filariasis among adults and children in northern coastal Tanzania from 2004 to 2011. Assessment of village-level distribution registers, combined with self-reported drug uptake surveys of adults, participant observation and interviews, revealed that at study sites in Pangani and Muheza districts the uptake of drugs was persistently low. The majority of people living at these highly endemic locations either did not receive or actively rejected free treatment. A combination of social, economic and political reasons explain the low uptake of drugs. These include a fear of treatment (attributable, in part, to a lack of trust in international aid and a questioning of the motives behind the distribution); divergence between biomedical and local understandings of lymphatic filariasis; and limited and ineffective communication about the rationale for mass treatment. Other contributory factors are the reliance upon volunteers for distribution within villages and, in some locations, strained relationships between different groups of people within villages as well as between local leaders and government officials. The article also highlights a disjuncture between self-reported uptake of drugs by adults at a village level and the higher uptake of drugs recorded in official reports. The latter informs claims that elimination will be a possibility by 2020. This gives voice to a broader problem: there is considerable pressure for those implementing MDA to report positive results. The very real challenges of making MDA work are pushed to one side - adding to a rhetoric of success at the expense of engaging with local realities. It is vital to address the kind of issues raised in this article if current attempts to eliminate lymphatic filariasis in mainland coastal Tanzania are to achieve their goal.

Supraspinally-administered agmatine attenuates the development of oral fentanyl self-administration
Wade, Carrie L.; Schuster, Daniel J.; Domingo, Kristine M.; Kitto, Kelley F.; Fairbanks, Carolyn A.
2009-01-01
The decarboxylation product of arginine, agmatine, has effectively reduced or prevented opioid-induced tolerance and dependence when given either systemically (intraperitoneally or subcutaneously) or centrally (intrathecally or intracerebroventricularly). Systemically administered agmatine also reduces the escalation phase of intravenous fentanyl self-administration in rats. The present study assessed whether centrally (intracerebroventricular, i.c.v.) delivered agmatine could prevent the development of fentanyl self-administration in mice. Mice were trained to respond under a fixed-ratio 1 (FR1) schedule for either fentanyl (0.7 μg/70 μl, p.o.) or food reinforcement. Agmatine (10 nmol/5 μl), injected i.c.v. 12-14h before the first session and every other evening (12-14h before session) for 2 weeks, completely attenuated oral fentanyl self-administration (but not food-maintained responding) compared to saline-injected controls. When agmatine was administered after fentanyl self-administration had been established (day 8) it had no attenuating effects on bar pressing. This dose of agmatine does not decrease locomotor activity as assessed by rotarod. The present findings significantly extend the previous observation that agmatine prevents opioid-maintained behavior to a chronic model of oral fentanyl self-administration as well as identifying a supraspinal site of action for agmatine inhibition of drug addiction.

Blockade of N-methyl-d-aspartate receptor (NMDA) by the noncompetitive NMDA receptor (NMDAR) antagonist MK-801 produces behavioral abnormalities and alterations in prefrontal cortex (PFC) functioning. Due to the critical role of the PFC in operant conditioning task learning, we evaluated the effects of acute, repeated postnatal injections of MK-801 (0.1mg/kg) on learning performance. We injected Long-Evans rats i.p. with MK-801 (0.1mg/kg) using three different administration schedules: injection 40 min before beginning the task (during) (n=12); injection twice daily for six consecutive days prior to beginning the experimental procedures (prior) (n=12); or twice daily subcutaneous injections from postnatal day 7 to 11 (postnatal) (n=12). Next, we orally administered risperidone (serotonin receptor 2A and dopamine receptor 2 antagonist, 1mg/kg) or buspirone (serotonin receptor 1A partial agonist, 10mg/kg) to animals treated with the MK-801 schedule described above. The postnatal and prior administration schedules produced severe learning deficits, whereas injection of MK-801 just before training sessions had only mild effects on acquisition of an operant conditioning. Risperidone was able to reverse the detrimental effect of MK-801 in the animals that were treated with MK-801 during and prior training sessions. In contrast, buspirone was only effective at mitigating the cognitive deficits induced by MK-801 when administered during the training procedures. The data demonstrates that NMDA antagonism disrupts basic mechanisms of learning in a simple PFC-mediated operant conditioning task, and that buspirone and risperidone failed to attenuate the learning deficits when NMDA neurotransmission was blocked in the early stages of the postnatal period.

The Food and Drug Administration (FDA) frequently uses its rulemaking process to establish or modify the way it regulates drugs, medical devices, and other medical products. The federal agency's rulemaking is controversial because of its perceived complexity, lack of transparency, and lengthy duration. To shed light on the FDA's rulemaking process, we examined the evolution of significant rules that the agency published during 2000-12 for drugs, devices, and other medical products. We found that the rules' median time to finalization was 7.3 years, with the pre-rule phase and postreview deliberation within the FDA accounting for the majority of that time. Rules that involved mandatory cost-benefit analyses were associated with an additional delay of approximately two years. We also found that longer review times were significantly associated with a reduction in the stringency of final rules, compared to the originally proposed versions. We recommend improving FDA's rulemaking by allocating additional resources to increase efficiency and by embarking on initiatives to promote transparency by the FDA and other parts of the executive branch.

Women have higher morning serum zolpidem concentrations than men after taking an evening dose, potentially leading to increased risk of harm. On 19 April 2013, the United States Food and Drug Administration required labeling changes for zolpidem, recommending an initial dose of no greater than 5 mg (immediate release) or 6.25 mg (controlled release) per night in women. The primary objective of this study was to compare prescribing practices before and after the 2013 zolpidem labeling change. A secondary objective was to evaluate serious adverse events potentially related to zolpidem. Electronic medical records of adults receiving care through the University of Colorado Health system were accessed for study inclusion if patients were provided a first-time prescription for zolpidem either prior to or after the Food and Drug Administration labeling change. Patients were randomly chosen from eight strata based on age, gender, and date of zolpidem initiation (before/after the labeling change). Demographic and zolpidem prescribing data were collected. Low-dose zolpidem was considered 5 mg (immediate release) or 6.25 mg (controlled release) daily or less. Documentation of potentially related serious adverse events within the patients' records was also evaluated. A total of 400 patients were included in the study. The overall percentage of patients prescribed low-dose zolpidem increased from 44% to 58% after the labeling change (p = 0.0020). In a pre-specified subgroup analysis, the percentage of patients prescribed low-dose zolpidem increased in all groups, including young men (38%-50%, p = 0.23), elderly men (34%-40%, p = 0.53), and elderly women (60%-74%, p = 0.14), but the change was only significant in young women (42%-70%, p = 0.0045). After Food and Drug Administration-mandated labeling changes for zolpidem in 2013, the percentage of overall patients in our health system, and specifically young women, with initial prescriptions for low

There is limited published scientific data on vaping recreational drugs other than cannabis. A recent review suggested that 15% of people vaping cannabis have also vaped a synthetic cannabinoid receptor agonist (SCRA) and identified over 300 Internet reports of e-liquid manufacture of recreational drugs and/or new psychoactive substances (NPS). To determine the prevalence of use of electronic vaping devices for recreational drug and NPS delivery in the UK. A voluntary online survey using a convenience sample of UK adult participants (aged 16 years old and over) identified by a market research company. Data was collected regarding demographics, smoking history, electronic vaping device history and recreational drug/NPS use and route of administration. There were 2501 respondents. The mean (±SD) age was 46.2 ± 16.8 years old. The commonest lifetime recreational drug used was Cannabis (818, 32.7%). The majority of respondents had smoked (1545, 61.8%) with 731 (29.2%) being current smokers. The most commonly used SCRA product was 'Spice Gold' (173, 6.9%) and SCRA compound was ADB-CHMICA (48, 1.9%). 861 (34.4%) had used an electronic vaping device; 340 (13.6%) having used them for recreational drug administration; 236 (9.4%) reporting current use. The commonest lifetime recreational drug to be vaped was cannabis (155, 65.7%), with electronic cigarettes (230, 48.2%) being the commonest reported route of SCRA compound administration. 9.4% of respondents currently use electronic vaping devices for recreational drug administration with 6.2% reporting lifetime cannabis vaping use. Further larger scale studies are required to help inform the appropriate treatment and primary prevention strategies. © The Author 2017.

Full Text Available TAS-102 significantly improves overall survival in patients with metastatic colorectal cancer. The most common adverse event of TAS-102 is bone marrow suppression, which leads to neutropenia. The incidence of neutropenia is high, and there is no known effective prevention method. Furthermore, the administration method of TAS-102 is complicated. We reported that neutropenia could be avoided by changing to a simple administration method of TAS-102.

Impact of Spacing of Practice on Learning Brand Name and Generic Drugs.
Terenyi, James; Anksorus, Heidi; Persky, Adam M
2018-02-01
Objective. To test the impact of schedules of retrieval practice on learning brand and generic name drug information in a self-paced course. Methods. Students completed weekly quizzes on brand and generic name conversions for 100 commonly prescribed drugs. Each student completed part of the drug list on a schedule of equal, expanding, or contracting spacing, one practice (massed) or study only in a partial block design. Results. On measures of long-term retention, the contracting spacing schedule led to superior retention (67%) compared to the massed practice (50%) and study-only condition (46%); contracting practice also was significantly higher than expanding practice (58%,) or equal practice (59%). Overall performance decreased by almost 50% (final exam 95%, long-term retention 55%) over a 6-week period. Conclusion. A contracting spacing schedule was the most effective schedule of practice, and all spacing schedules were superior to massed practice or study-only conditions.

An investigation on impacts of scheduling configurations on Mississippi biology subject area testing
Marchette, Frances Lenora
The purpose of this mixed modal study was to compare the results of Biology Subject Area mean scores of students on a 4 x 4 block schedule, A/B block schedule, and traditional year-long schedule for 1A to 5A size schools. This study also reviewed the data to determine if minority or gender issues might influence the test results. Interviews with administrators and teachers were conducted about the type of schedule configuration they use and the influence that the schedule has on student academic performance on the Biology Subject Area Test. Additionally, this research further explored whether schedule configurations allow sufficient time for students to construct knowledge. This study is important to schools, teachers, and administrators because it can assist them in considering the impacts that different types of class schedules have on student performance and if ethnic or gender issues are influencing testing results. This study used the causal-comparative method for the quantitative portion of the study and constant comparative method for the qualitative portion to explore the relationship of school schedules on student academic achievement on the Mississippi Biology Subject Area Test. The aggregate means of selected student scores indicate that the Mississippi Biology Subject Area Test as a measure of student performance reveals no significant difference on student achievement for the three school schedule configurations. The data were adjusted for initial differences of gender, minority, and school size on the three schedule configurations. The results suggest that schools may employ various schedule configurations and expect student performance on the Mississippi Biology Subject Area Test to be unaffected. However, many areas of concern were identified in the interviews that might impact on school learning environments. These concerns relate to effective classroom management, the active involvement of students in learning, the adequacy of teacher education

Accelerated approval of oncology products: the food and drug administration experience.
Johnson, John R; Ning, Yang-Min; Farrell, Ann; Justice, Robert; Keegan, Patricia; Pazdur, Richard
2011-04-20
We reviewed the regulatory history of the accelerated approval process and the US Food and Drug Administration (FDA) experience with accelerated approval of oncology products from its initiation in December 11, 1992, to July 1, 2010. The accelerated approval regulations allowed accelerated approval of products to treat serious or life-threatening diseases based on surrogate endpoints that are reasonably likely to predict clinical benefit. Failure to complete postapproval trials to confirm clinical benefit with due diligence could result in removal of the accelerated approval indication from the market. From December 11, 1992, to July 1, 2010, the FDA granted accelerated approval to 35 oncology products for 47 new indications. Clinical benefit was confirmed in postapproval trials for 26 of the 47 new indications, resulting in conversion to regular approval. The median time between accelerated approval and regular approval of oncology products was 3.9 years (range = 0.8-12.6 years) and the mean time was 4.7 years, representing a substantial time savings in terms of earlier availability of drugs to cancer patients. Three new indications did not show clinical benefit when confirmatory postapproval trials were completed and were subsequently removed from the market or had restricted distribution plans implemented. Confirmatory trials were not completed for 14 new indications. The five longest intervals from receipt of accelerated approval to July 1, 2010, without completion of trials to confirm clinical benefit were 10.5, 6.4, 5.5, 5.5, and 4.7 years. The five longest intervals between accelerated approval and successful conversion to regular approval were 12.6, 9.7, 8.1, 7.5, and 7.4 years. Trials to confirm clinical benefit should be part of the drug development plan and should be in progress at the time of an application seeking accelerated approval to prevent an ineffective drug from remaining on the market for an unacceptable time.

Schedule-induced polydipsia: a rat model of obsessive-compulsive disorder.
Platt, Brian; Beyer, Chad E; Schechter, Lee E; Rosenzweig-Lipson, Sharon
2008-04-01
Obsessive-compulsive disorder (OCD) is difficult to model in animals due to the involvement of both mental (obsessions) and physical (compulsions) symptoms. Due to limitations of using animals to evaluate obsessions, OCD models are limited to evaluation of the compulsive and repetitive behaviors of animals. Of these, models of adjunctive behaviors offer the most value in regard to predicting efficacy of anti-OCD drugs in the clinic. Adjunctive behaviors are those that are maintained indirectly by the variables that control another behavior, rather than directly by their own typical controlling variables. Schedule-induced polydipsia (SIP) is an adjunctive model in which rats exhibit exaggerated drinking behavior (polydipsia) when presented with food pellets under a fixed-time schedule. The polydipsic response is an excessive manifestation of a normal behavior (drinking), providing face validity to the model. Furthermore, clinically effective drugs for the treatment of OCD decrease SIP. This protocol describes a rat SIP model of OCD and provides preclinical data for drugs that decrease polydipsia and are clinically effective in the treatment of OCD.

Drug abuse and dependence present significant health burdens for our society, affecting roughly 10% of the population. Stress likely contributes to the development and persistence of drug use; for example, rates of substance dependence are elevated among individuals diagnosed with post-traumatic stress disorder (PTSD). Thus, understanding the interaction between stress and drug use, and associated neuroadaptations, is key for developing therapies to combat substance use disorders. For this purpose, many rodent models of the effects of stress exposure on substance use have been developed; the models can be classified according to three categories of stress exposure: developmental, adult nonsocial, and adult social. The present review addresses preclinical findings on the effect of each type of trauma on responses to and self-administration of drugs of abuse by focusing on a key exemplar for each category. In addition, the potential efficacy of targeting neuropeptide systems that have been implicated in stress responses and stress system neuroadaptation in order to treat comorbid PTSD and substance abuse will be discussed.

Full Text Available The aim of this work was to study the effect of site of intramuscular administration of anaesthetic drugs on the course of immobilisation in macaque monkeys (Macaca mulatta. Twenty macaque monkeys were given medetomidine (25 µg·kg-1 and ketamine (3 mg·kg-1 intramuscularly to the deltoid (n = 10 animals or gluteus (n = 10 animals muscles. Behavioural changes, loss of aggressiveness, immobilisation time and cardiorespiratory changes were recorded. The effect of drugs was reversed after 20 min by i.m. administration of atipamezole at the dose of 250 µg·kg-1. Highly significant differences (P < 0.001 were found between groups with gluteal or deltoid administration of drugs on the onset of immobilisation effect (71.3 s and 108.3 s, respectively, and immobilisation time (152.7 s and 254.4 s, respectively. In the gluteus muscle group, the grasp reflex was still present at the beginning of immobilisation and slowly wore off in 15–45 s. The same was valid for muscle tone. There were no differences in cardiorespiratory parameters in any of the groups. Animals of both groups recovered in 3–6 min after atipamezole administration. Administration of drugs to the deltoid muscle resulted in a more rapid onset and increased effect of immobilisation than administration to the gluteus muscle. Both in veterinary and human medicine, injection to the deltoid muscle may be more convenient in all cases, when rapid and more prominent effect is desirable as in premedication before surgery or in emergency medicine. The study is the first to compare the effect of administering drugs to different muscles and the results may improve the practice of intramuscular injections in animals and in humans.

Tumor-induced angiogenesis leads to the development of leaky tumor vessels devoid of structural and morphological integrity. Due to angiogenesis, elevated interstitial fluid pressure (IFP) and low blood perfusion emerge as common properties of the tumor microenvironment that act as barriers for drug delivery. In order to overcome these barriers, normalization of vasculature is considered to be a viable option. However, insight is needed into the phenomenon of normalization and in which conditions it can realize its promise. In order to explore the effect of microenvironmental conditions and drug scheduling on normalization benefit, we build a mathematical model that incorporates tumor growth, angiogenesis and IFP. We administer various theoretical combinations of antiangiogenic agents and cytotoxic nanoparticles through heterogeneous vasculature that displays a similar morphology to tumor vasculature. We observe differences in drug extravasation that depend on the scheduling of combined therapy; for concurrent therapy, total drug extravasation is increased but in adjuvant therapy, drugs can penetrate into deeper regions of tumor.

An innovative nanocapsule formulation for parenteral administration using selected vegetable oils (mango, jojoba, pequi, oat, annatto, calendula, and chamomile) was developed that has the potential to encapsulate various drugs. The vegetable oil-loaded nanocapsules were prepared by interfacial deposition and compared with capric/caprylic triglyceride-loaded lipid core nanocapsules. The major objective was to investigate the effect of vegetable oils on particle size distribution and physical stability and to determine the hemolytic potential of the nanocapsules, considering their applicability for intravenous administration. Taking into account the importance of accurately determining particle size for the selected route of administration, different size characterization techniques were employed, such as Laser Diffraction, Dynamic Light Scattering, Multiple Light Scattering, Nanoparticle Tracking Analysis, and Transmission Electronic Microscopy. Laser diffraction studies indicated that the mean particle size of all nanocapsules was below 300 nm. For smaller particles, the laser diffraction and multiple light scattering data were in agreement (D[3,2]-130 nm). Dynamic light scattering and nanoparticle tracking analysis, two powerful techniques that complement each other, exhibited size values between 180 and 259 nm for all nanoparticles. Stability studies demonstrated a tendency of particle creaming for jojoba-nanocapsules and sedimentation for the other nanoparticles; however, no size variation occurred over 30 days. The hemolysis test proved the hemocompatibility of all nanosystems, irrespective of the type of oil. Although all developed nanocapsules presented the potential for parenteral administration, jojoba oil-loaded nanocapsules were selected as the most promising nanoformulation due to their low average size and high particle size homogeneity.

Therapeutic drug monitoring (TDM) of second-line antituberculosis drugs would allow for optimal individualized dosage adjustments and improve drug safety and therapeutic outcomes. To evaluate the pharmacokinetic (PK) characteristics of clinically relevant, multidrug treatment regimens and to improve the feasibility of TDM, we conducted an open-label, multiple-dosing study with 16 healthy subjects who were divided into two groups. Cycloserine (250 mg), p-aminosalicylic acid (PAS) (5.28 g), and prothionamide (250 mg) twice daily and pyrazinamide (1,500 mg) once daily were administered to both groups. Additionally, levofloxacin (750 mg) and streptomycin (1 g) once daily were administered to group 1 and moxifloxacin (400 mg) and kanamycin (1 g) once daily were administered to group 2. Blood samples for PK analysis were collected up to 24 h following the 5 days of drug administration. The PK parameters, including the maximum plasma concentration (Cmax) and the area under the plasma concentration-time curve during a dosing interval at steady state (AUCτ), were evaluated. The correlations between the PK parameters and the concentrations at each time point were analyzed. The mean Cmax and AUCτ, respectively, for each drug were as follows: cycloserine, 24.9 mg/liter and 242.3 mg · h/liter; PAS, 65.9 mg/liter and 326.5 mg · h/liter; prothionamide, 5.3 mg/liter and 22.1 mg · h/liter; levofloxacin, 6.6 mg/liter and 64.4 mg · h/liter; moxifloxacin, 4.7 mg/liter and 54.2 mg · h/liter; streptomycin, 42.0 mg/liter and 196.7 mg · h/liter; kanamycin, 34.5 mg/liter and 153.5 mg · h/liter. The results indicated that sampling at 1, 2.5, and 6 h postdosing is needed for TDM when all seven drugs are administered concomitantly. This study indicates that PK characteristics must be considered when prescribing optimal treatments for patients. (This study has been registered at ClinicalTrials.gov under registration no. NCT02128308.). Copyright © 2015, American Society for

MabThera is an essential component of the standard-of-care regimens in the treatment of non-Hodgkin lymphoma and Chronic Lymphatic Leukemia. MabThera for subcutaneous injection is a novel line extension that has been approved by the European Medicines Agency for the treatment of patients with follicular lymphoma and diffuse large B-cell lymphoma. This study aimed to evaluate in-use stability data of MabThera subcutaneous drug-product solution in single-use syringes for subcutaneous administration according to the European Medicines Agency guideline. The drug-product solution was exposed to material contact surfaces of five different administration setups commonly used in subcutaneous drug delivery. MabThera subcutaneous was transferred under aseptic conditions into polypropylene and polycarbonate syringes and stored for 1, 2, and 4 weeks at 2°C to 8°C followed by 24 hours at 30°C. After storage, subcutaneous administration was simulated and MabThera subcutaneous drug-product solution quality attributes were evaluated by using compendial physico-chemical tests, as well as suitable and validated molecule- and formulation-specific analytical methods. MabThera subcutaneous vials were treated and analyzed in parallel. The physico-chemical results of MabThera subcutaneous in the different setups were comparable to the control for all timepoints. No change in drug-product quality after storage and simulated administration was found compared to the control. However, since single-dose products do not contain preservatives, microbial contamination and growth needs to be avoided and product sterility needs to be ensured. The results showed that MabThera subcutaneous remains compatible and stable, from a physico-chemical perspective, for up to 4 weeks at 2°C to 8°C followed by 24 hours at 30°C with the contact materials tested in this study. In order to avoid and minimize microbial growth, MabThera subcutaneous should be used immediately after removal from the original

Andrographis paniculata Nees (Acanthacae) is commonly used medicinal plant in the traditional. Unani and Ayurvedic medicinal systems. It has broad range of pharmacological effects such as hepatoprotective, antioxidant, antivenom, antifertility, inhibition of replication of the HIV virus, antimalarial, antifungal, antibacterial, antidiabetic, suppression of various cancer cells and anti-inflammatory properties. Andrographolide (AN) is one of the active constituent of the A. paniculata Nees extract (APE). They have been found in many traditional herbal formulations in India and proven to be effective as anti-inflammatory drug To evaluate the pharmacokinetic and pharmacodynamic (anti-arthritic) herb-drug interactions of A. paniculata Nees extract (APE) and pure andrographolide (AN) with etoricoxib (ETO) after oral co-administration in wistar rats. After oral co-administration of APE (200mg/Kg) and AN (60mg/kg) with ETO (10mg/kg) in rats, drug concentrations in plasma were determined using HPLC method. The main pharmacokinetic parameters of Cmax, tmax, t1/2, MRT, Vd, CL, and AUC were calculated by non-compartment model. Change in paw volume, mechanical nociceptive threshold, mechanical hyperalgesia, histopathology and hematological parameters were evaluated to study antiarthritic activity. Co-administration of ETO with APE and pure AN decreased systemic exposure level of each compound in vivo. The Cmax, AUC, t1/2 of ETO was decreased whereas Vd and CL of ETO was increased significantly after co-administration of ETO with pure AN and APE. In pharmacodynamic study, ETO alone and ETO+APE (10+200mg/kg) groups exhibited significant synergistic anti-arthritic activity as compared to groups ETO+AN, APE and AN alone. The results obtained from this study suggested that ETO, APE and pure AN existed pharmacokinetic herb-drug interactions in rat which is correlated with anti-arthritic study. Physicians and patients using A. paniculata should have the knowledge about its possible

Heterogeneous Effects of a Nonlinear Price Schedule for Outpatient Care.
Farbmacher, Helmut; Ihle, Peter; Schubert, Ingrid; Winter, Joachim; Wuppermann, Amelie
2017-10-01
Nonlinear price schedules generally have heterogeneous effects on health-care demand. We develop and apply a finite mixture bivariate probit model to analyze whether there are heterogeneous reactions to the introduction of a nonlinear price schedule in the German statutory health insurance system. In administrative insurance claims data from the largest German health insurance plan, we find that some individuals strongly react to the new price schedule while a second group of individuals does not react. Post-estimation analyses reveal that the group of the individuals who do not react to the reform includes the relatively sick. These results are in line with forward-looking behavior: Individuals who are already sick expect that they will hit the kink in the price schedule and thus are less sensitive to the co-payment.

Data reported directly by patients about how they feel and function are rarely included in oncology drug labeling in the United States, in contrast to Europe and to nononcology labeling in the United States, where this practice is more common. Multiple barriers exist, including challenges unique to oncology trials, and industry's concerns regarding cost, logistical complexities, and the Food and Drug Administration's (FDA's) rigorous application of its 2009 guidance on the use of patient-reported outcome (PRO) measures. A panel consisting of representatives of industry, FDA, the PRO Consortium, clinicians, and patients was assembled at a 2014 workshop cosponsored by FDA to identify practical recommendations for overcoming these barriers. Key recommendations included increasing proactive encouragement by FDA to clinical trial sponsors for including PROs in drug development programs; provision of comprehensive PRO plans by sponsors to FDA early in drug development; promotion of an oncology-specific PRO research agenda; development of an approach to existing ("legacy") PRO measures, when appropriate (focused initially on symptoms and functional status); and increased FDA and industry training in PRO methodology. FDA has begun implementing several of these recommendations.

This work addresses the refinery scheduling problem using mathematical programming techniques. The solution adopted was to decompose the entire refinery model into a crude oil scheduling and a product scheduling problem. The envelope for the crude oil scheduling problem is composed of a terminal, a pipeline and the crude area of a refinery, including the crude distillation units. The solution method adopted includes a decomposition technique based on the topology of the system. The envelope for the product scheduling comprises all tanks, process units and products found in a refinery. Once crude scheduling decisions are Also available the product scheduling is solved using a rolling horizon algorithm. All models were tested with real data from PETROBRAS' REFAP refinery, located in Canoas, Southern Brazil. (author)

The dopamine (DA) D2 and D3 receptors have been associated with cocaine abuse. A recent study with the D3 receptor (D3R) partial agonist PG619 found that it attenuated cocaine-induced reinstatement and the D2-like receptor antagonist buspirone has shown positive outcomes in two studies of cocaine abuse in monkeys. However, a recent clinical trial indicated that buspirone did not improve abstinence in treatment-seeking cocaine abusers. The objective of the study was to examine PG619 and buspirone under a food-drug choice paradigm in order to better model the clinical findings. In addition, we extended the characterization of both compounds to include methamphetamine (MA) self-administration (SA). Six adult male rhesus monkeys were trained to respond under a concurrent food (1.0-g pellets) and drug (0.01-0.3 mg/kg/injection cocaine or MA) choice paradigm in which complete SA dose-response curves were determined each session (N = 3/group). Monkeys received 5 days of treatment with either PG619 (0.1-3.0 mg/kg, i.v.) or buspirone (0.01-1.0 mg/kg, i.m.). In a follow-up study, the SA doses were reduced (0.003-0.1 mg/kg/injection) to increase reinforcement frequency and buspirone was retested. PG619 did not affect cocaine or MA choice, while buspirone increased low-dose cocaine choice. Changing the SA doses increased the number of reinforcers received each session, but buspirone did not decrease drug choice. Consistent with clinical findings, these results do not support the use of buspirone for psychostimulant abuse and suggest that food-drug choice paradigms may have greater predictive validity than the use of other schedules of reinforcement.

Posttraumatic stress disorder (PTSD) is often comorbid with substance use disorders (SUD). Single prolonged stress (SPS) is a well-validated rat model of PTSD that provides a framework to investigate drug-induced behaviors as a preclinical model of the comorbidity. We hypothesized that cocaine sensitization and self-administration would be increased following exposure to SPS. Male Sprague-Dawley rats were exposed to SPS or control treatment. After SPS, cocaine (0, 10 or 20 mg/kg, i.p.) was administered for 5 consecutive days and locomotor activity was measured. Another cohort was assessed for cocaine self-administration (0.1 or 0.32 mg/kg/i.v.) after SPS. Rats were tested for acquisition, extinction and cue-induced reinstatement behaviors. Control animals showed a dose-dependent increase in cocaine-induced locomotor activity after acute cocaine whereas SPS rats did not. Using a sub-threshold sensitization paradigm, control rats did not exhibit enhanced locomotor activity at Day 5 and therefore did not develop behavioral sensitization, as expected. However, compared to control rats on Day 5 the locomotor response to 20mg/kg repeated cocaine was greatly enhanced in SPS-treated rats, which exhibited enhanced cocaine locomotor sensitization. The effect of SPS on locomotor activity was unique in that SPS did not modify cocaine self-administration behaviors under a simple schedule of reinforcement. These data show that SPS differentially affects cocaine-mediated behaviors causing no effect to cocaine self-administration, under a simple schedule of reinforcement, but significantly augmenting cocaine locomotor sensitization. These results suggest that SPS shares common neurocircuitry with stimulant-induced plasticity, but dissociable from that underlying psychostimulant-induced reinforcement. Copyright © 2015.

Despite their ubiquitous use and several recent health controversies involving cosmetics and personal care products for children, the Food and Drug Administration has little oversight of these products and relies on consumer-submitted adverse event reports. We assessed the recently released Center for Food Safety and Applied Nutrition's Adverse Event Reporting System database for adverse event reports submitted to the Food and Drug Administration for baby personal care products and to determine whether useful insights can be derived. We extracted the Center for Food Safety and Applied Nutrition's Adverse Event Reporting System data file from 2004 to 2016 and examined the subset classified according to the Food and Drug Administration-designated product class as a baby product. Events were manually categorized into product type and symptom type to assess for trends. Only 166 total adverse events were reported to the Food and Drug Administration for baby products from 2004 to 2016. The majority of reports indicated rash or other skin reaction; 46% of reported events led to a health care visit. Pediatric dermatologists should consider submitting cosmetics and personal care product adverse event reports and encouraging consumers to do so likewise in situations in which a product adversely affects a child's health. © 2018 Wiley Periodicals, Inc.

Full Text Available Blinding trachoma is targeted for elimination by 2020 using the SAFE strategy (Surgery, Antibiotics, Facial cleanliness, and Environmental improvements. Annual mass drug administration (MDA with azithromycin is a cornerstone of this strategy. If baseline prevalence of clinical signs of trachomatous inflammation - follicular among 1-9 year-olds (TF1-9 is ≥ 10% but 30%, 7 or more annual MDAs may be required to achieve the target. There are five years left before the 2020 deadline to eliminate blinding trachoma. Low endemic settings are poised to succeed in their elimination goals. However, newly-identified high prevalence districts warrant immediate inclusion in the global program. Intensified application of the SAFE strategy is needed in order to guarantee blinding trachoma elimination by 2020.

Flexible job-shop scheduling problem (FJSP), which is proved to be NP-hard, is an extension of the classical job-shop scheduling problem. In this paper, we propose a new genetic algorithm (NGA) to solve FJSP to minimize makespan. This new algorithm uses a new chromosome representation and adopts different strategies for crossover and mutation. The proposed algorithm is validated on a series of benchmark data sets and tested on data from a drug manufacturing company. Experimental results prove that the NGA is more efficient and competitive than some other existing algorithms.

In the United States of America (USA), the abuse potential assessment of a drug is performed as part of the safety evaluation of a drug under development, and to evaluate if the drug needs to be subject to controls that would minimize the abuse of the drug once on the market. The assessment of the abuse potential of new drugs consists of a scientific and medical evaluation of all data related to abuse of the drug. This paper describes the regulatory framework for evaluating the abuse potential of new drugs, in general, including novel stimulants. The role of the United States Food and Drug Administration (FDA) in the evaluation of the abuse potential of drugs, and its role in drug control are also discussed. A definition of abuse potential, an overview of the currently accepted approaches to evaluating the abuse potential of a drug, as well as a description of the criteria that applies when recommending a specific level of control (i.e., a Schedule) for a drug under the Controlled Substances Act (CSA).

In 2007, the Food and Drug Administration requested that manufacturers of all approved gadolinium-based contrast agents (GBCAs), drugs widely used in magnetic resonance imaging, use nearly identical text in their product labeling to describe the risk of nephrogenic systemic fibrosis (NSF). Accumulating information about NSF risks led to revision of the labeling text for all of these drugs in 2010. The present report summarizes the basis and purpose of this class-labeling approach and describes some of the related challenges, given the evolutionary nature of the NSF risk evidence. The class-labeling approach for presentation of product risk is designed to decrease the occurrence of NSF and to enhance the safe use of GBCAs in radiologic practice. © RSNA, 2012.

Chiron Corporation and Hoffman-LaRoche announced a filing of a New Drug Application with the Food and Drug Administration (FDA) to market Vitrasert, its intraocular implant which delivers ganciclovir directly to the eye for treatment of CMV retinitis. Clinical trials show that Vitrasert offers a clinical improvement versus intravenous ganciclovir in further delaying progression of CMV retinitis in the treated eye. One study reported that the median time to progression of CMV retinitis was 186 days for eyes receiving Vitrasert compared to 72 days for eyes receiving intravenous ganciclovir therapy. Chiron's intraocular implant contains ganciclovir embedded in a polymer-based system that slowly releases the drug into the eye for up to eight months. Two additional trials are underway.

Since the mid-1990s, there have been calls to make naloxone, a prescription-only medicine in many countries, available to heroin and other opioid users and their peers and family members to prevent overdose deaths. In Australia there were calls for a trial of peer naloxone in 2000, yet at the end of that year, heroin availability and harm rapidly declined, and a trial did not proceed. In other countries, a number of peer naloxone programs have been successfully implemented. Although a controlled trial had not been conducted, evidence of program implementation demonstrated that trained injecting drug-using peers and others could successfully administer naloxone to reverse heroin overdose, with few, if any, adverse effects. In 2009 Australian drug researchers advocated the broader availability of naloxone for peer administration in cases of opioid overdose. Industrious local advocacy and program development work by a number of stakeholders, notably by the Canberra Alliance for Harm Minimisation and Advocacy, a drug user organisation, contributed to the rollout of Australia's first prescription naloxone program in the Australian Capital Territory (ACT). Over the subsequent 18 months, prescription naloxone programs were commenced in four other Australian states. The development of Australia's first take-home naloxone program in the ACT has been an 'ice-breaker' for development of other Australian programs. Issues to be addressed to facilitate future scale-up of naloxone programs concern scheduling and cost, legal protections for lay administration, prescribing as a barrier to scale-up; intranasal administration, administration by service providers and collaboration between stakeholders. © 2014 Australasian Professional Society on Alcohol and other Drugs.

Caffeine increases the motivation to obtain non-drug reinforcers in rats
Sheppard, A. Brianna; Gross, Skyler C.; Pavelka, Sarah A.; Hall, Melanie J.; Palmatier, Matthew I.
2012-01-01
BACKGROUND Caffeine is widely considered to be a reinforcer in humans, but this effect is difficult to measure in non-human animals. We hypothesized that caffeine may have dual reinforcing effects comparable to nicotine - limited primary reinforcing effects, but potent reinforcement enhancing effects. The present studies tested this hypothesis by investigating the effect of caffeine on responding for non-drug rewards. METHODS In two experiments, rats were shaped to respond on a progressive ratio (PR) schedule for sucrose solution (20% w/v; Experiment 1) or a fixed ratio 2 (FR2) schedule for a moderately reinforcing visual stimulus (VS; Experiment 2). Pretreatment with various doses of caffeine (0–50 mg/kg, intraperitoneal injection) were administered prior to tests over successive week days (M-F). In Experiment 1, acute administration of low-moderate caffeine doses (6.25–25 mg/kg) increased responding for sucrose under the PR schedule. This effect of caffeine declined over the initial 15 test days. In Experiment 2, only acute pretreatment with 12.5 mg/kg caffeine increased responding for the visual stimulus and complete tolerance to this effect of caffeine was observed over the 15 days of testing. In follow up tests we found that abstinence periods of 4 and 8 days resulted in incomplete recovery of the enhancing effects of caffeine. CONCLUSION The findings suggest that caffeine enhances the reinforcing effects of non-drug stimuli, but that the pharmacological profile of these effects may differ from other psychomotor stimulants.

Intravenous alcohol self-administration in the P rat.
Windisch, Kyle A; Kosobud, Ann E K; Czachowski, Cristine L
2014-08-01
Alcohol consumption produces a complex array of effects that can be divided into two types: the explicit pharmacological effects of ethanol (which can be temporally separate from time of intake) and the more temporally "relevant" effects (primarily olfactory and taste) that bridge the time from intake to onset of the pharmacological effects. Intravenous (IV) self-administration of ethanol limits the confounding "non-pharmacological" effects associated with oral consumption, allows for controlled and precise dosing, and bypasses first order absorption kinetics, allowing for more direct and better-controlled assessment of alcohol's effect on the brain. IV ethanol self-administration has been reliably demonstrated in mouse and human experimental models; however, models of IV self-administration have been historically problematic in the rat. An operant multiple-schedule study design was used to elucidate the role of each component of a compound IV-ethanol plus oral-sucrose reinforcer. Male alcohol-preferring P rats had free access to both food and water during all IV self-administration sessions. Animals were trained to press a lever for orally delivered 1% sucrose (1S) on a fixed ratio 4 schedule, and then surgically implanted with an indwelling jugular catheter. Animals were then trained to respond on a multiple FR4-FR4 schedule composed of alternating 2.5-min components across 30-min sessions. For the multiple schedule, two components were used: an oral 1S only and an oral 1S plus IV 20% ethanol (25 mg/kg/injection). Average total ethanol intake was 0.47 ± 0.04 g/kg. We found significantly higher earning of sucrose-only reinforcers and greater sucrose-lever error responding relative to the compound oral-sucrose plus IV-ethanol reinforcer. These response patterns suggest that sucrose, not ethanol, was responsible for driving overall responding. The work with a compound IV ethanol-oral sucrose reinforcer presented here suggests that the existing intravenous ethanol

Adverse event management in mass drug administration for neglected tropical diseases.
Caplan, Arthur; Zink, Amanda
2014-03-01
The ethical challenges of reporting and managing adverse events (AEs) and serious AEs (SAEs) in the context of mass drug administration (MDA) for the treatment of neglected tropical diseases (NTDs) require reassessment of domestic and international policies on a global scale. Although the World Health Organization has set forth AE/SAE guidelines specifically for NTD MDA that incorporate suspected causality, and recommends that only SAEs get reported in this setting, most regulatory agencies continue to require the reporting of all SAEs exhibiting even a merely temporal relationship to activities associated with an MDA program. This greatly increases the potential for excess "noise" and undue risk aversion and is not only impractical but arguably unethical where huge proportions of populations are being treated for devastating diseases, and no good baseline exists against which to compare possible AE/SAE reports. Other population-specific variables that might change the way drug safety ought to be assessed include differing efficacy rates of a drug, background morbidity/mortality rates of the target disease in question, the growth rate of the incidence of disease, the availability of rescue or salvage therapies, and the willingness of local populations to take risks that other populations might not. The fact that NTDs are controllable and potentially eradicable with well-tolerated, effective, existing drugs might further alter our assessment of MDA safety and AE/SAE tolerability. At the same time, diffuseness of population, communication barriers, lack of resources, and other difficult surveillance challenges may present in NTD-affected settings. These limitations could impair the ability to monitor an MDA program's success, as well as hinder efforts to obtain informed consent or provide rescue therapy. Denying beneficial research interventions and MDA programs intended to benefit millions requires sound ethical justification based on more than the identification of

Understanding factors surrounding the implementation process of mass drug administration for lymphatic filariasis (MDA for LF) elimination programmes is critical for successful implementation of similar interventions. The sub-Saharan Africa (SSA) region records the second highest prevalence of the disease and subsequently several countries have initiated and implemented MDA for LF. Systematic reviews have largely focused on factors that affect coverage and compliance, with less attention on the implementation of MDA for LF activities. This review therefore seeks to document facilitators and barriers to implementation of MDA for LF in sub-Saharan Africa. A systematic search of databases PubMed, Science Direct and Google Scholar was conducted. English peer-reviewed publications focusing on implementation of MDA for LF from 2000 to 2016 were considered for analysis. Using thematic analysis, we synthesized the final 18 articles to identify key facilitators and barriers to MDA for LF programme implementation. The main factors facilitating implementation of MDA for LF programmes were awareness creation through innovative community health education programmes, creation of partnerships and collaborations, integration with existing programmes, creation of morbidity management programmes, motivation of community drug distributors (CDDs) through incentives and training, and management of adverse effects. Barriers to implementation included the lack of geographical demarcations and unregistered migrations into rapidly urbanizing areas, major disease outbreaks like the Ebola virus disease in West Africa, delayed drug deliveries at both country and community levels, inappropriate drug delivery strategies, limited number of drug distributors and the large number of households allocated for drug distribution.

Full Text Available With an increasing number of cancer patients seeking an improved quality of life, complementary and alternative therapies are becoming more common ways to achieve such improvements. The potential risks of concurrent administration are serious and must be addressed. However, comprehensive evidence for the risks and benefits of combining anticancer drugs with traditional herbs is rare. Pharmacokinetic investigations are an efficient way to understand the influence of concomitant remedies. Therefore, this study aimed to collect the results of pharmacokinetic studies relating to the concurrent use of cancer chemotherapy and complementary and alternative therapies. According to the National Health Insurance (NHI database in Taiwan and several publications, the three most commonly prescribed formulations for cancer patients are Xiang-Sha-Liu-Jun-Zi-Tang, Jia-Wei-Xiao-Yao-San and Bu-Zhong-Yi-Qi-Tang. The three most commonly prescribed single herbs for cancer patients are Hedyotis diffusa, Scutellaria barbata, and Astragalus membranaceus. Few studies have discussed herb–drug interactions involving these herbs from a pharmacokinetics perspective. Here, we reviewed Jia-Wei-Xiao-Yao-San, Long-Dan-Xie-Gan-Tang, Curcuma longa and milk thistle to provide information based on pharmacokinetic evidence for healthcare professionals to use in educating patients about the risks of the concomitant use of various remedies.

Medicare and the Veterans Health Administration (VA) both finance large outpatient prescription drug programs, though in very different ways. In the ongoing debate on how to control Medicare spending, some suggest that Medicare should negotiate directly with drug manufacturers, as the VA does. In this article we relate the role of interest groups to policy differences between Medicare and the VA and, in doing so, explain why such a large change to the Medicare drug program is unlikely. We argue that key policy differences are attributable to stable differences in interest group involvement. While this stability makes major changes in Medicare unlikely, it suggests the possibility of leveraging VA drug purchasing to achieve savings in Medicare. This could be done through a VA-administered drug-only benefit for Medicare-enrolled veterans. Such a partnership could incorporate key elements of both programs: capacity to accept large numbers of enrollees (like Medicare) and leverage to negotiate prescription drug prices (like the VA). Moreover, it could be implemented at no cost to the VA while achieving savings for Medicare and beneficiaries.

A comprehensive review was performed to investigate the effect of route of administration on medication adherence and persistence in rheumatoid arthritis (RA) and to compare adherence/persistence with oral medications between RA and a non-painful disease (dyslipidemia). Comprehensive database searches were performed to identify studies investigating medication adherence and/or persistence in adults with RA receiving conventional synthetic or biologic agents. Similar searches were performed for studies of patients with dyslipidemia receiving statins. Studies had to be published after 1998 in English and involve ≥6 months' follow up. Adherence and persistence were compared between the different routes of drug administration in RA, and between the two diseases for oral medications. A total of 35 and 28 papers underwent data extraction for RA and dyslipidemia, respectively. Within the constraints of the analysis, adherence and persistence rates appeared broadly similar for the different routes of drug administration in RA. Adherence to oral medications was also broadly similar across the two diseases, but persistence was lower in dyslipidemia. Poor adherence has clinical consequences in both diseases: greater disease activity and risk of flare in RA, and increased serum cholesterol levels and risk of heart and cerebrovascular disease in dyslipidemia. Over 1-3 years, poor adherence to biologic RA medications led to increased resource use and medical costs but lower total direct costs due to reduced biologic drug costs. Conversely, poor adherence to dyslipidemia medications resulted in increased total direct costs. In both diseases, adherence improved with patient education/support. The route of drug administration and the symptomatic (pain) nature of the disease do not appear to be dominant factors for drug adherence or persistence in RA. The wide range of adherence and persistence values and definitions across studies made comparisons between drug formulations and

Anti-Obesity Agents and the US Food and Drug Administration.
Casey, Martin F; Mechanick, Jeffrey I
2014-09-01
Despite the growing market for obesity care, the US Food and Drug Administration (FDA) has approved only two new pharmaceutical agents-lorcaserin and combination phentermine/topiramate-for weight reduction since 2000, while removing three agents from the market in the same time period. This article explores the FDA's history and role in the approval of anti-obesity medications within the context of a public health model of obesity. Through the review of obesity literature and FDA approval documents, we identified two major barriers preventing fair evaluation of anti-obesity agents including: (1) methodological pitfalls in clinical trials and (2) misaligned values in the assessment of anti-obesity agents. Specific recommendations include the use of adaptive (Bayesian) design protocols, value-based analyses of risks and benefits, and regulatory guidance based on a comprehensive, multi-platform obesity disease model. Positively addressing barriers in the FDA approval process of anti-obesity agents may have many beneficial effects within an obesity disease model.

Optimized Treatment Schedules for Chronic Myeloid Leukemia.
Directory of Open Access Journals (Sweden)
Qie He
2016-10-01
Full Text Available Over the past decade, several targeted therapies (e.g. imatinib, dasatinib, nilotinib have been developed to treat Chronic Myeloid Leukemia (CML. Despite an initial response to therapy, drug resistance remains a problem for some CML patients. Recent studies have shown that resistance mutations that preexist treatment can be detected in a substantial number of patients, and that this may be associated with eventual treatment failure. One proposed method to extend treatment efficacy is to use a combination of multiple targeted therapies. However, the design of such combination therapies (timing, sequence, etc. remains an open challenge. In this work we mathematically model the dynamics of CML response to combination therapy and analyze the impact of combination treatment schedules on treatment efficacy in patients with preexisting resistance. We then propose an optimization problem to find the best schedule of multiple therapies based on the evolution of CML according to our ordinary differential equation model. This resulting optimization problem is nontrivial due to the presence of ordinary different equation constraints and integer variables. Our model also incorporates drug toxicity constraints by tracking the dynamics of patient neutrophil counts in response to therapy. We determine optimal combination strategies that maximize time until treatment failure on hypothetical patients, using parameters estimated from clinical data in the literature.

Bioavailability and bioequivalence study is one of the most frequently performed investigations in clinical trials. Bioequivalence testing is based on the assumption that 2 drug products will be therapeutically equivalent when they are equivalent in the rate and extent to which the active drug ingredient or therapeutic moiety is absorbed and becomes available at the site of drug action. In recent years there has been a significant growth in published papers that use in silico studies based on mathematical simulations to analyze pharmacokinetic and pharmacodynamic properties of drugs, including bioavailability and bioequivalence aspects. The goal of this study is to evaluate the usefulness of in silico studies as a tool in the planning of bioequivalence, bioavailability and other pharmacokinetic assays, e.g., to determine an appropriate sampling schedule. Monte Carlo simulations were used to define adequate blood sampling schedules for a bioequivalence assay comparing 2 different formulations of cefadroxil oral suspensions. In silico bioequivalence studies comparing different formulation of cefadroxil oral suspensions using various sampling schedules were performed using models. An in vivo study was conducted to confirm in silico results. The results of in silico and in vivo bioequivalence studies demonstrated that schedules with fewer sampling times are as efficient as schedules with larger numbers of sampling times in the assessment of bioequivalence, but only if T max is included as a sampling time. It was also concluded that in silico studies are useful tools in the planning of bioequivalence, bioavailability and other pharmacokinetic in vivo assays. © Georg Thieme Verlag KG Stuttgart · New York.

Schedule sensitivity has usually been examined either through a multiple schedule or through changes in schedules after steady-state responding has been established. This study compared the effects of these two procedures when various instructions were given. Fifty-five college students responded in two 32-min sessions under a multiple fixed-ratio 18/differential-reinforcement-of-low-rate 6-s schedule, followed by one session of extinction. Some subjects received no instructions regarding the appropriate rates of responding, whereas others received instructions to respond slowly, rapidly, or both. Relative to the schedule in operation, the instructions were minimal, partially inaccurate, or accurate. When there was little schedule sensitivity in the multiple schedule, there was little in extinction. When apparently schedule-sensitive responding occurred in the multiple schedule, however, sensitivity in extinction occurred only if differential responding in the multiple schedule could not be due to rules supplied by the experimenter. This evidence shows that rule-governed behavior that occurs in the form of schedule-sensitive behavior may not in fact become schedule-sensitive even though it makes contact with the scheduled reinforcers.

Schedule goals for civilian radioactive waste management - Can we have confidence?
International Nuclear Information System (INIS)
Bartlett, John W.
1992-01-01
The schedule goals for the Civilian Radioactive Waste Management Program are to begin spent fuel receipt from reactors in 1998 and to begin waste disposal in 2010. Although there are various reasons for these goals, the most important is to set demanding goals and be responsible for achieving them. Meeting these goals requires taking into account an array of facilitators and potential inhibitors that affect schedule confidence. Facilitators include actions to prioritize the program, and make its operations efficient. These include actions to baseline activities, emphasize communications with constituencies, use help from others, and facilitate the licensing process. Inhibitors include problems in monitored storage facilities negotiations, obstruction by the State of Nevada, funding deficiencies, and technical uncertainties at Yucca Mountain. At the present time, the program can, in principle meet its schedule goals. In the near-term, the linchpin of schedule confidence is Congressional action to match the Administration's commitment to progress. (author)

Tick-borne encephalitis (TBE), which is endemic across large regions of Europe and Asia, is most effectively prevented through vaccination. Three-dose primary TBE vaccination schedules are either rapid (0,7,21-days) or conventional (0,28-84-days, 9-12-months). The second dose can also be administered at 14 days for faster priming and sero-protection). Areas covered: We used a three-step selection process to identify 21 publications comparing the immunogenicity and/or safety of different schedules. Expert commentary: Priming with two or three TBE vaccine doses was highly immunogenic. After conventional priming (0-28 days), 95% adults and ≥95% children had neutralization test (NT) titers ≥10 at 14 days post-dose-2 compared with 92% adults and 99% children at 21 days post-dose-3 (rapid schedule). Most subjects retained NT titers ≥10 at day 300. A single booster dose induced a strong immune response in all subjects irrespective of primary vaccination schedule or elapsed time since priming. GMT peaked at 42 days post-dose-1 (i.e., 21 days post-dose 3 [rapid-schedule], or 14-28 days post-dose-2 [conventional-schedule]), and declined thereafter. Adverse events were generally rare and declined with increasing doses. In the absence of data to recommend one particular schedule, the regimen choice will remain at the physician's discretion, based on patient constraints and availability.

Studies using targeted gene deletion in mice have revealed distinct roles for individual isozymes of the protein kinase C (PKC) family of enzymes in regulating sensitivity to various drugs of abuse. These changes in drug sensitivity are associated with altered patterns of drug self-administration. The purpose of this review is to summarize behavioral studies conducted on mice carrying targeted deletions of genes encoding specific PKC isozymes (namely the beta, gamma, delta, and epsilon isozymes), and to critically evaluate the possibility of using pharmacological inhibitors of specific PKC isozymes as modulators of the sensitivity to various drugs of abuse, as well as potential aids in the treatment of substance use disorders.

Our initial investigations into restenosis inhibition by local drug delivery were prompted by reports on an improved outcome of coronary interventions, including a lower rate of target lesion revascularisation, when the intervention was performed with an ionic instead of non-ionic contrast medium. Although this was not confirmed in an animal study, the short exposure of the vessel wall to paclitaxel dissolved in contrast agent or coated on balloons proved to be efficacious. A study comparing three methods of local drug delivery to the coronary artery in pigs indicated the following order of efficacy in inhibiting neointimal proliferation: paclitaxel-coated balloons > sirolimus-eluting stents, sustained drug release > paclitaxel in contrast medium. Cell culture experiments confirmed that cell proliferation can be inhibited by very short exposure to the drug. Shorter exposure times require higher drug concentrations. Effective paclitaxel concentrations in porcine arteries are achieved when the drug is dissolved in contrast medium or coated on balloons. Paclitaxel is an exceptional drug in that it stays in the treated tissue for a long time. This may explain the long-lasting efficacy of paclitaxel-coated balloons, but does not disprove the hypothesis that the agent blocks a process initiating long-lasting excessive neointimal proliferation, which occurs early after vessel injury.

Full Text Available Background: Women have higher morning serum zolpidem concentrations than men after taking an evening dose, potentially leading to increased risk of harm. On 19 April 2013, the United States Food and Drug Administration required labeling changes for zolpidem, recommending an initial dose of no greater than 5 mg (immediate release or 6.25 mg (controlled release per night in women. Objectives: The primary objective of this study was to compare prescribing practices before and after the 2013 zolpidem labeling change. A secondary objective was to evaluate serious adverse events potentially related to zolpidem. Methods: Electronic medical records of adults receiving care through the University of Colorado Health system were accessed for study inclusion if patients were provided a first-time prescription for zolpidem either prior to or after the Food and Drug Administration labeling change. Patients were randomly chosen from eight strata based on age, gender, and date of zolpidem initiation (before/after the labeling change. Demographic and zolpidem prescribing data were collected. Low-dose zolpidem was considered 5 mg (immediate release or 6.25 mg (controlled release daily or less. Documentation of potentially related serious adverse events within the patients’ records was also evaluated. Results: A total of 400 patients were included in the study. The overall percentage of patients prescribed low-dose zolpidem increased from 44% to 58% after the labeling change (p = 0.0020. In a pre-specified subgroup analysis, the percentage of patients prescribed low-dose zolpidem increased in all groups, including young men (38%–50%, p = 0.23, elderly men (34%–40%, p = 0.53, and elderly women (60%–74%, p = 0.14, but the change was only significant in young women (42%–70%, p = 0.0045. Conclusion: After Food and Drug Administration–mandated labeling changes for zolpidem in 2013, the percentage of overall patients in our health

Full Text Available Abstract Background Nonmedical prescription opioid use has emerged as a major public health concern in recent years, particularly in rural Appalachia. Little is known about the routes of administration (ROA involved in nonmedical prescription opioid use among rural and urban drug users. The purpose of this study was to describe rural-urban differences in ROA for nonmedical prescription opioid use. Methods A purposive sample of 212 prescription drug users was recruited from a rural Appalachian county (n = 101 and a major metropolitan area (n = 111 in Kentucky. Consenting participants were given an interviewer-administered questionnaire examining sociodemographics, psychiatric disorders, and self-reported nonmedical use and ROA (swallowing, snorting, injecting for the following prescription drugs: buprenorphine, fentanyl, hydrocodone, hydromorphone, methadone, morphine, OxyContin® and other oxycodone. Results Among urban participants, swallowing was the most common ROA, contrasting sharply with substance-specific variation in ROA among rural participants. Among rural participants, snorting was the most frequent ROA for hydrocodone, methadone, OxyContin®, and oxycodone, while injection was most common for hydromorphone and morphine. In age-, gender-, and race-adjusted analyses, rural participants had significantly higher odds of snorting hydrocodone, OxyContin®, and oxycodone than urban participants. Urban participants had significantly higher odds of swallowing hydrocodone and oxycodone than did rural participants. Notably, among rural participants, 67% of hydromorphone users and 63% of morphine users had injected the drugs. Conclusions Alternative ROA are common among rural drug users. This finding has implications for rural substance abuse treatment and harm reduction, in which interventions should incorporate methods to prevent and reduce route-specific health complications of drug use.

Background: Intraperitoneal adhesion formation is a serious postsurgical issue. Adhesions develop after damage to the peritoneum by surgery, irradiation, infection or trauma. Objectives: Using a rat model, we compared the effectiveness of systemic and intraperitoneally administered common immunosuppressive drugs for prevention of postoperative intraperitoneal adhesions. Materials and Methods: Peritoneal adhesions were induced in 98 female Wistar-Albino rats by cecal abrasion and peritoneal excision. Rats were randomly separated into seven groups, each containing fourteen rats, and the standard experimental model was applied to all of rats. 14 days later, rats were euthanized, intraperitoneal adhesions were scored and tissues were examined histologically using hematoxylin/eosin and Masson’s trichrome staining. Results: Throughout the investigation, no animal died during or after surgery. In all of experimental groups, decrease in fibrosis was statistically significant. Decrease in fibrosis was most prominently in intraperitoneal tacrolimus group (P = 0.000), and decrease was least in intraperitoneal cyclosporine group (P = 0.022). Vascular proliferation was significantly decreased in all experimental groups (P < 0.05) except for systemic tacrolimus group (P = 0.139). Most prominent reduction in vascular proliferation was in intraperitoneal tacrolimus group (P = 0.000). Conclusions: Administration of immunosuppressive drugs is effective for prevention of intraperitoneal adhesions. PMID:24693396

Rotavirus shedding following administration of RV3-BB human neonatal rotavirus vaccine.
Cowley, Daniel; Boniface, Karen; Bogdanovic-Sakran, Nada; Kirkwood, Carl D; Bines, Julie E
2017-08-03
The RV3-BB human neonatal rotavirus vaccine aims to provide protection from severe rotavirus disease from birth. A phase IIa safety and immunogenicity trial was undertaken in Dunedin, New Zealand between January 2012 and April 2014. Healthy, full-term (≥ 36 weeks gestation) babies, who were 0-5 d old were randomly assigned (1:1:1) to receive 3 doses of oral RV3-BB vaccine with the first dose given at 0-5 d after birth (neonatal schedule), or the first dose given at about 8 weeks after birth (infant schedule), or to receive placebo (placebo schedule). Vaccine take (serum immune response or stool shedding of vaccine virus after any dose) was detected after 3 doses of RV3-BB vaccine in >90% of participants when the first dose was administered in the neonatal and infant schedules. The aim of the current study was to characterize RV3-BB shedding and virus replication following administration of RV3-BB in a neonatal and infant vaccination schedule. Shedding was defined as detection of rotavirus by VP6 reverse transcription polymerase chain reaction (RT-PCR) in stool on days 3-7 after administration of RV3-BB. Shedding of rotavirus was highest following vaccination at 8 weeks of age in both neonatal and infant schedules (19/30 and 17/27, respectively). Rotavirus was detected in stool on days 3-7, after at least one dose of RV3-BB, in 70% (21/30) of neonate, 78% (21/27) of infant and 3% (1/32) placebo participants. In participants who shed RV3-BB, rotavirus was detectable in stool on day 1 following RV3-BB administration and remained positive until day 4-5 after administration. The distinct pattern of RV3-BB stool viral load demonstrated using a NSP3 quantitative qRT-PCR in participants who shed RV3-BB, suggests that detection of RV3-BB at day 3-7 was the result of replication rather than passage through the gastrointestinal tract.

Exposure to stimuli and environments associated with drug use is considered one of the most important contributors to relapse among substance abusers. Neuroimaging studies have identified neural circuits underlying these responses in cocaine-dependent subjects. But these studies are often difficult to interpret because of the heterogeneity of the participants, substances abused, and differences in drug histories and social variables. Therefore, the goal of this study was to assess the functional effects of exposure to cocaine-associated stimuli in a non-human primate model of cocaine self-administration, providing precise control over these variables, with the 2-[(14) C]deoxyglucose method. Rhesus monkeys self-administered 0.3 mg/kg/injection cocaine (n = 4) under a fixed-interval 3-minute (FI 3-min) schedule of reinforcement (30 injections/session) for 100 sessions. Control animals (n = 4) underwent identical schedules of food reinforcement. Sessions were then discontinued for 30 days, after which time, monkeys were exposed to cocaine- or food-paired cues, and the 2-[(14) C]deoxyglucose experiment was conducted. The presentation of the cocaine-paired cues resulted in significant increases in functional activity within highly restricted circuits that included portions of the pre-commissural striatum, medial prefrontal cortex, rostral temporal cortex and limbic thalamus when compared with control animals presented with the food-paired cues. The presentation of cocaine-associated cues increased brain functional activity in contrast to the decreases observed after cocaine consumption. Furthermore, the topography of brain circuits engaged by the expectation of cocaine is similar to the distribution of effects during the earliest phases of cocaine self-administration, prior to the onset of neuroadaptations that accompany chronic cocaine exposure. © 2015 Society for the Study of Addiction.

The parenteral administration of combinations of drugs is often necessary in palliative medicine, particularly in the terminal stage of life, when patients are no longer able to take medication orally. The use of infusers to administer continuous subcutaneous infusions is a well-established practice in the palliative care setting and enables several drugs to be given simultaneously, avoiding the need for repeated administrations and the effects of peaks and troughs in the doses of medication. The method is also appreciated by patients and caregivers in the home care setting because the devices and infusion sites are easy to manage. Despite their frequent use, however, the mixtures of drugs adopted in clinical practice are sometimes not supported by reliable data concerning their chemical and physical compatibility. The present study investigates the chemical compatibility of binary mixtures (morphine with ketorolac) and the physical compatibility of binary (morphine or methadone with ketorolac) or ternary mixtures (morphine with ketorolac and/or haloperidol, and/or dexamethasone, and/or metoclopramide, and/or hyoscine butylbromide) with a view to reducing the aleatory nature of the empirical use of such combinations, thereby increasing their safety and clinical appropriateness.

Postpartum depression is a mood disorder that commonly affects women during the early postpartum period. The objective of this study was to analyse the association of postpartum depression with drugs (including contraceptive devices and implants) with spontaneously reported adverse events reported in the US Food and Drug Administration Adverse Event Reporting System database. Retrospective study. Reports of postpartum depression events between 2004-2015 were analysed with a reporting odds ratio (ROR) algorithm. The Medical Dictionary for Regulatory Activities was used to identify postpartum depression. The reporting odds ratios (95% confidence intervals, CI) of levonorgestrel (an intrauterine device with progestogen), etonogestrel (a hormonal contraceptive implant), sertraline and drospirenone (an oral contraceptive) were 12.5 (8.7-18.0), 14.0 (8.5-22.8), 12.2 (6.5-23.1) and 5.4 (2.7-10.9) respectively. Among the drugs in the US Food and Drug Administration Adverse Event Reporting System database, the use of contraceptives or an intrauterine device with progestogen might convey risk for postpartum depression.

Full Text Available Abstract Background Observational research frequently uses administrative codes for mental health or substance use diagnoses and for important behaviours such as suicide attempts. We sought to validate codes (International Classification of Diseases, 9th edition, clinical modification diagnostic and E-codes entered in Veterans Health Administration administrative data for patients with depression versus a gold standard of electronic medical record text ("chart notation". Methods Three random samples of patients were selected, each stratified by geographic region, gender, and year of cohort entry, from a VHA depression treatment cohort from April 1, 1999 to September 30, 2004. The first sample was selected from patients who died by suicide, the second from patients who remained alive on the date of death of suicide cases, and the third from patients with a new start of a commonly used antidepressant medication. Four variables were assessed using administrative codes in the year prior to the index date: suicide attempt, alcohol abuse/dependence, drug abuse/dependence and tobacco use. Results Specificity was high (≥ 90% for all four administrative codes, regardless of the sample. Sensitivity was ≤75% and was particularly low for suicide attempt (≤ 17%. Positive predictive values for alcohol dependence/abuse and tobacco use were high, but barely better than flipping a coin for illicit drug abuse/dependence. Sensitivity differed across the three samples, but was highest in the suicide death sample. Conclusions Administrative data-based diagnoses among VHA records have high specificity, but low sensitivity. The accuracy level varies by different diagnosis and by different patient subgroup.

To study the effect of aluminume adjuvant and immunization schedule on immunogenicity of Sabin inactivated poliovirus vaccine. Four batches of Sabin IPV were produced by different concentrations of type 1, 2, and 3 poliovirus and administrated on three-dose schedule at 0, 1, 2 months and 0, 2, 4 months on rats. Serum samples were collected one month after each dose and neutralizing antibody titers against three types poliovirus were determined by micro-neutralization assay. The GMTs of neutralizing antibodies against three types poliovirus increased significantly and the seropositivity rates were 100% in all groups after 3 doses. There was no significant difference between two immunization schedules, and the 0, 2, 4 month schedule could induce higher level neutralizing antibody compared to the 0, 1, 2 month schedule. The groups with aluminum adjuvant could induce higher level neutralizing antibody compared to the groups without adjuvant. Aluminum djuvant and immunization schedule could improve the immunogenicity of Sabin IPV.

Project management with dynamic scheduling baseline scheduling, risk analysis and project control
Vanhoucke, Mario
2013-01-01
The topic of this book is known as dynamic scheduling, and is used to refer to three dimensions of project management and scheduling: the construction of a baseline schedule and the analysis of a project schedule's risk as preparation of the project control phase during project progress. This dynamic scheduling point of view implicitly assumes that the usability of a project's baseline schedule is rather limited and only acts as a point of reference in the project life cycle.

The Food and Drug Administration (FDA) is further delaying, until December 1, 2006, the effective date of certain requirements of a final rule published in the Federal Register of December 3, 1999 (64 FR 67720). In the Federal Register of May 3, 2000 (65 FR 25639), the agency delayed until October 1, 2001, the effective date of certain requirements in the final rule relating to wholesale distribution of prescription drugs by distributors that are not authorized distributors of record, and distribution of blood derivatives by entities that meet the definition of a "health care entity" in the final rule. The agency further delayed the effective date of these requirements in three subsequent Federal Register notices. Most recently, in the Federal Register of January 31, 2003 (68 FR 4912), FDA delayed the effective date until April 1, 2004. This action further delays the effective date of these requirements until December 1, 2006. The final rule implements the Prescription Drug Marketing Act of 1987 (PDMA), as modified by the Prescription Drug Amendments of 1992 (PDA), and the Food and Drug Administration Modernization Act of 1997 (the Modernization Act). The agency is taking this action to address concerns about the requirements in the final rule raised by affected parties. As explained in the SUPPLEMENTARY INFORMATION section, FDA is working with stakeholders through its counterfeit drug initiative to facilitate widespread, voluntary adoption of track and trace technologies that will generate a de facto electronic pedigree, including prior transaction history back to the original manufacturer, as a routine course of business. If this technology is widely adopted, it is expected to help fulfill the pedigree requirements of the PDMA and obviate or resolve many of the concerns that have been raised with respect to the final rule by ensuring that an electronic pedigree travels with a drug product at all times. Therefore, it is necessary to delay the effective date of Sec

Despite the cost saving role of generic anti-epileptic drugs (AEDs), debate exists as to whether generic substitution of branded AEDs may lead to therapeutic failure and increased toxicity. This study compared adverse event (AE) reporting rates for brand vs. authorized generic (AG) vs. generic AEDs. Since AGs are pharmaceutically identical to brand but perceived as generics, the generic vs. AG comparison minimized potential bias against generics. Events reported to the U.S. Food and Drug Administration Adverse Event Reporting System between January 2004 to March 2015 with lamotrigine, carbamazepine, and oxcarbazepine listed as primary or secondary suspect were classified as brand, generic, or AG based on the manufacturer. Disproportionality analyses using the reporting odds ratio (ROR) assessed the relative rate of reporting of labeled AEs compared to reporting these events with all other drugs. The Breslow-Day statistic compared RORs across brand, AG, and other generics using a Bonferroni-corrected Pbrand and generics for all three drugs of interest (Breslow-Day Pbrands and generics have similar reporting rates after accounting for generic perception biases. Disproportional suicide reporting was observed for generics compared with AGs and brand, although this finding needs further study. Copyright © 2017 Elsevier B.V. All rights reserved.

Zohydro approval by food and drug administration: controversial or frightening?

The actions and regulations of the Food and Drug Administration (FDA) are crucial to the entire population of the U.S., specifically the public who take a multitude of drugs and providers who prescribe drugs and devices. Further, the FDA is relevant to investors, specifically in regards to biotech and pharmaceutical companies involved in developing new drugs. The FDA has been criticized for a lack of independence on the one hand and excessive regulatory and expanding authority without evidence and consistency of the actions on the other hand. The FDA approved a single-entity, long-acting, hydrocodone product (Zohydro, Zogenix, San Diego, CA) on October 25, 2013, against the recommendation of the FDA's own appointed scientific advisory panel, which voted 11 to 2 against the approval of Zohydro. Subsequent to the approval, multiple consumer safety organizations, health care agencies, addiction treatment providers, professional organizations, and other groups on the frontline of the opioid addiction epidemic have expressed concern. In addition, the US Congress and various state attorneys general raised serious concerns about the approval of Zohydro, which is highly addictive and may enhance the opioid addiction epidemic. Supporters of Zohydro contend that it is necessary and essential to manage chronic pain and improve functional status with no additional risk. Over the past 15 years, prescriptions for opioids have skyrocketed with the United States consuming more than 84% of the global oxycodone and more than 99% of the hydrocodone supply. The sharp increase in opioid prescribing has led to parallel increases in opioid addiction and overdose deaths, surpassing motor vehicle injuries in the U.S. Recent studies assessing the trends of medical use and misuse of opioid analgesics from 2000 to 2011 have concluded that the present trend of the continued increase in the medical use of opioid analgesics appears to contribute to increasing misuse, resulting in multiple health

Washington's marine oil spill compensation schedule - simplified resource damage assessment
International Nuclear Information System (INIS)
Geselbracht, L.; Logan, R.
1993-01-01
The Washington State Preassessment Screening and Oil Spill Compensation Schedule Rule (Chapter 173-183 Washington Administrative Code), which simplifies natural resource damage assessment for many oil spill cases, became effective in May 1992. The approach described in the rule incorporates a number of preconstructed rankings that rate environmental sensitivity and the propensity of spilled oil to cause environmental harm. The rule also provides guidance regarding how damages calculated under the schedule should be reduced to take into account actions taken by the responsible party that reduce environmental injury. To apply the compensation schedule to marine estuarine spills, the resource trustees need only collect a limited amount of information such as type of product spilled, number of gallons spilled, compensation schedule subregions the spill entered, season of greatest spill impact, percent coverage of habitats affected by the spill, and actions taken by the responsible party. The result of adding a simplified tool to the existing assortment of damage assessment approaches is that resource trustees will now be able to assess damages for most oil spill cases and shift more effort than was possible in the past to resource restoration

Although computerized operations have significant gains realized in many areas, one area, scheduling, has enjoyed few benefits from automation. The traditional methods of industrial engineering and operations research have not proven robust enough to handle the complexities associated with the scheduling of realistic problems. To address this need, NASA has developed the computer-aided scheduling system (COMPASS), a sophisticated, interactive scheduling tool that is in wide-spread use within NASA and the contractor community. Therefore, COMPASS provides no explicit support for the large class of problems in which several people, perhaps at various locations, build separate schedules that share a common pool of resources. This research examines the issue of distributing scheduling, as applied to application domains characterized by the partial ordering of tasks, limited resources, and time restrictions. The focus of this research is on identifying issues related to distributed scheduling, locating applicable problem domains within NASA, and suggesting areas for ongoing research. The issues that this research identifies are goals, rescheduling requirements, database support, the need for communication and coordination among individual schedulers, the potential for expert system support for scheduling, and the possibility of integrating artificially intelligent schedulers into a network of human schedulers.

The Food and Drug Administration and Drug Legalization: A Brief Model of Regulation
Kalam, Murad

This paper offers a brief model of FDA regulation of currently illegal narcotics in the United States. Given that nearly three out of four Americans believe that the drug war has failed, recent calls from prominent liberal and conservative thinkers to legalize drugs, and state “compassionate use†ballot initiatives, future drug legalization is at least conceivable in the United States. Yet, how would the FDA regulate NLD’s under its current st...

Risk management and post-marketing surveillance of CNS drugs.
Henningfield, Jack E; Schuster, Charles R
2009-12-01
Drugs affecting the central nervous system span a broad range of chemical entities, dosage forms, indications, and risks. Unintended consequences include potential abuse and overdose in non-patient drug abusers, deliberate tampering of drug dosage forms, and criminal behavior associated with diversion. Regulators must consider diverse factors to find the appropriate conditions of approval to minimize unintended consequences while enabling a level of access desired by health care providers and patients. This commentary appears as part of a special issue of Drug and Alcohol Dependence that focuses on risk management and post-marketing surveillance and addresses key issues that pose real-world challenges to pharmaceutical sponsors and regulators in particular. For example, in the U.S., Controlled Substances Act drug scheduling can be considered a risk management strategy but its legal authorities and administrative processes are independent from those of risk management (including Risk Evaluation and Mitigation Strategies or REMS); better harmonization of these approaches is vital from drug development and regulatory perspectives. Risk management would ideally be implemented on a strong science foundation demonstrating that the tools employed to mitigate risks and ensure safe use are effective. In reality, research and evaluation of tools in this area is in its infancy and will necessarily be an evolutionary process; furthermore, there is little precedent for linking interventions and program evolution to unintended consequences such as regional outbreaks of abuse and diversion. How such issues are resolved has the potential to stimulate or stifle innovations in drug development and advance or imperil health care.

Home Health Care for California's Injured Workers: Options for Implementing a Fee Schedule.
Wynn, Barbara O; Boustead, Anne
2015-07-15
The California Department of Industrial Relations/Division of Worker's Compensation asked RAND to provide technical assistance in developing a fee schedule for home health services provided to injured workers. The fee schedule needs to address the full spectrum of home health services ranging from skilled nursing and therapy services to unskilled personal care or chore services that may be provided by family members. RAND researchers consulted with stakeholders in the California workers' compensation system to outline issues the fee schedule should address, reviewed home health fee schedules used by other payers, and conducted interviews with WC administrators from other jurisdictions to elicit their experiences. California stakeholders identified unskilled attendant services as most problematic in determining need and payment rates, particularly services furnished by family members. RAND researchers concentrated on fee schedule options that would result in a single fee schedule covering the full range of home health care services furnished to injured workers and made three sets of recommendations. The first set pertains to obtaining additional information that would highlight the policy issues likely to occur with the implementation of the fee schedule and alternatives for assessing an injured worker's home health care needs. Another approach conforms most closely with the Labor Code requirements. It would integrate the fee schedules used by Medicare, In-Home Health Supportive Services, and the federal Office of Workers' Compensation. The third approach would base the home health fee schedule on rules used by the federal Office of Workers' Compensation.

Full Text Available Pharmacological manipulation of the type 5 metabotropic glutamate (mGlu5 receptor alters various addiction related behaviors such as drug self-administration and the extinction and reinstatement of drug-seeking behavior. However, the effects of pharmacological modulation of mGlu5 receptors on brain reward function have not been widely investigated. We examined the effects of acute administration of positive and negative allosteric modulators (PAMs and NAMs, respectively on brain reward function by assessing thresholds for intracranial self-stimulation (ICSS. In addition, when acute effects were observed, we examined potential changes in altered ICSS thresholds following repeated administration. Male Sprague-Dawley rats were implanted with bipolar electrodes into the medial forebrain bundle and trained to respond for ICSS, followed by assessment of effects of mGlu5 ligands on ICSS thresholds using a discrete trials current intensity threshold determination procedure. Acute administration of the selective mGlu5 NAMs MTEP (0, 0.3, 1 or 3 mg/kg and fenobam (0, 3, 10, or 30 mg/kg dose-dependently increased ICSS thresholds (~70% at the highest dose tested, suggesting a deficit in brain reward function. Acute administration of the mGlu5 PAMs CDPPB (0, 10, 30 and 60 mg/kg or ADX47273 (0, 10, 30 and 60 mg/kg was without effect at any dose tested. When administered once daily for 5 consecutive days, the development of tolerance to the ability of threshold-elevating doses of MTEP and fenobam to increase ICSS thresholds was observed. We conclude that mGlu5 PAMs and NAMs differentially affect brain reward function, and that tolerance to the ability of mGlu5 NAMs to reduce brain reward function develops with repeated administration. These brain reward deficits should be taken into consideration when interpreting acute effects of mGlu5 NAMs on drug self-administration, and repeated administration may be an effective method to reduce these deficits.

This article reports recent findings from a program of experimental research examining the effects of adapting judicial supervision to the risk level of drug-abusing offenders. Prior studies revealed that high-risk participants with (1) antisocial personality disorder or (2) a history of drug abuse treatment performed significantly better in drug court when they were scheduled to attend frequent, bi-weekly judicial status hearings in court. Low-risk participants performed equivalently regardless of the schedule of court hearings. The current study prospectively matched misdemeanor drug court clients to the optimal schedule of court hearings based upon an assessment of their risk status, and compared outcomes to those of clients randomly assigned to the standard schedule of court hearings. Results confirmed that high-risk participants graduated at a higher rate, provided more drug-negative urine specimens at 6 months post-admission, and reported significantly less drug use and alcohol intoxication at 6 months post-admission when they were matched to bi-weekly hearings as compared to the usual schedule of hearings. These findings yield practical information for enhancing the efficacy and cost-efficiency of drug court services. Directions for future research on adaptive programming for drug offenders are discussed. PMID:17071020

The aim of the study is to develop a self-nanoemulsifying drug delivery system (SNEDDS) based on thiolated chitosan for oral insulin administration. The preparations were characterized by particle size, entrapment efficiency, stability and drug release. Serum insulin concentrations were determined after oral administration of all formulations. Insulin SNEDDS formulation was served as control. The optimized SNEDDS consists of 65% (w/w) miglyol 840, 25% (w/w) cremophor EL, 10% (w/w) co-solvents (a mixture of DMSO and glycerol). The formulations in the presence or absence of insulin (5mg/mL) were spherical with the size range between 80 and 160 nm. Entrapment efficiency of insulin increased significantly when the thiolated chitosan was employed (95.14±2.96%), in comparison to the insulin SNEDDS (80.38±1.22%). After 30 min, the in vitro release profile of insulin from the nanoemulsions was markedly increased compared to the control. In vivo results showed that insulin/thiolated chitosan SNEDDS displayed a significant increase in serum insulin (p-value=0.02) compared to oral insulin solution. A new strategy to combine SNEDDS and thiolated chitosan described in the study would therefore be a promising and innovative approach to improve oral bioavailability of insulin.

Nuclear waste management and the impact of Carter Administration policies
International Nuclear Information System (INIS)
Williams, R.F.
1979-01-01
The impact of Carter Administration's policies on the nuclear waste management program are evaluated in this article. The waste management program faces numerous inconsistencies resulting from: a lack of a clearly defined schedule and division of responsibility; the requirement to meet conflicting procedural requirements; and the lack of clear statements from the President and Congress supporting the major programs. Some of the ramifications of these points are discussed with reference to the schedule for the 3 key program elements: National Waste Terminal Storage (NWTS) Facility scheduled for commercial operation in 1985 to handle commercial high-level wastes; the Spent Unreprocessed Fuel (SURF) Facility scheduled for operation in 1985 to handle spent fuel from commercial power plants; the Waste Isolation Pilot Plant (WIPP) scheduled for operation in 1983 or 1984 for the disposal of TRU defense wastes. Possible avenues for improvement are suggested

PRESYNAPTIC DOPAMINE MODULATION BY STIMULANT SELF ADMINISTRATION
España, Rodrigo A.; Jones, Sara R.
2013-01-01
The mesolimbic dopamine system is an essential participant in the initiation and modulation of various forms of goal-directed behavior, including drug reinforcement and addiction processes. Dopamine neurotransmission is increased by acute administration of all drugs of abuse, including the stimulants cocaine and amphetamine. Chronic exposure to these drugs via voluntary self-administration provides a model of stimulant abuse that is useful in evaluating potential behavioral and neurochemical adaptations that occur during addiction. This review describes commonly used methodologies to measure dopamine and baseline parameters of presynaptic dopamine regulation, including exocytotic release and reuptake through the dopamine transporter in the nucleus accumbens core, as well as dramatic adaptations in dopamine neurotransmission and drug sensitivity that occur with acute non-contingent and chronic, contingent self-administration of cocaine and amphetamine.

Radiation induced white matter necrosis in the rat spinal cord is preceded by changes in permeability of the blood brain-barrier, reduced blood flow, and infarction so that the necrosis is an ischemic necrosis. Attempts have been made to modify this developing pathology by the administration of drugs post-irradiation but just prior to the changes in vascular permeability. Verapamyl, a calcium channel blocker, had no effect on the development of ataxia. Dipyridamole, a drug which increases blood flow and reduces thrombosis, delayed and reduced the onset of ataxia. A low iron diet and desferrioxamine which reduces reperfusion injury also delayed and reduced ataxia. These results support the thesis that vascular changes are an important pathway in the development of radiation necrosis and that reperfusion injury is an important factor in the development and exacerbation of radiation damage to the spinal cord

This article argues that contrary to the claims made by research stakeholders in industry, academia and government, the shift in public policy since the enactment of the Food and Drug Administration Modernization Act (FDAMA) of 1997 and its financial incentives to industry to test drugs on children, has had a deleterious impact on children's dignity, health and welfare. Those lucrative incentives offered an opportunity to accelerate the pace of FDA approval for pediatric drug marketing. FDAMA resulted in a radical shift in federal policy to accommodate an expansion of pediatric trials. Children who are precluded from exercising a human adult's right to informed consent to research are increasingly sought as test subjects even when the trials offer no potential benefit for them. Prior to FDAMA children were protected under federal regulations that prohibited their recruitment for experiments that were not in their best interest. This article discusses eight cases and controversies demonstrating that children have been subjected to experiments that exposed them to pain, discomfort, and serious risks of harm. Babies have died testing a lethal heartburn drug; children have been subjected to "forced dose titration" in antidepressant drug trials that resulted in several suicide attempts. Toddlers are currently being subjected to methylphenidate dose tolerance tests without evidence of any pathological condition. Healthy teenagers are being exposed to antipsychotic drugs known to induce severe pathological side effects in speculative "schizophrenia prevention" experiments.

Clinical trials for vaccine development in registry of Korea Food and Drug Administration.
Kang, Seog-Youn
2013-01-01
Based on the action plan "Ensuring a stable supply of National Immunization Program vaccines and sovereignty of biopharmaceutical products," Korea Food and Drug Administration (KFDA) has made efforts to develop vaccines in the context of self reliance and to protect public health. Along with the recognized infrastructures for clinical trials, clinical trials for vaccines have also gradually been conducted at multinational sites as well as at local sites. KFDA will support to expand six to eleven kinds of vaccines by 2017. In accordance with integrated regulatory system, KFDA has promoted clinical trials, established national lot release procedure, and strengthened good manufacturing practices inspection and post marketing surveillance. Against this backdrop, KFDA will support the vaccine development and promote excellent public health protection.

To determine the proportion of restaurants that will be required to post calorie information under the Food and Drug Administration's menu-labeling regulations in 4 New Jersey cities. We classified geocoded 2014 data on 1753 restaurant outlets in accordance with the Food and Drug Administration's guidelines, which will require restaurants with 20 or more locations nationwide to post calorie information. We used multivariate logistic regression analyses to assess the association between menu-labeling requirements and census tract characteristics. Only 17.6% of restaurants will be affected by menu labeling; restaurants in higher-income tracts have higher odds than do restaurants in lower-income tracts (odds ratio [OR] = 1.55; P = .02). Restaurants in non-Hispanic Black (OR = 1.62; P = .02) and mixed race/ethnicity (OR = 1.44; P = .05) tracts have higher odds than do restaurants in non-Hispanic White tracts of being affected. Additional strategies are needed to help consumers make healthy choices at restaurants not affected by the menu-labeling law. These findings have implications for designing implementation strategies for the law and for evaluating its impact.

Cognitive dysfunction may be a core feature of major depressive disorder, including affective processing bias, abnormal response to negative feedback, changes in decision making, and increased impulsivity. Accordingly, a translational medicine paradigm predicts clinical action of novel antidepressants by examining drug-induced changes in affective processing bias. With some exceptions, these concepts have not been systematically applied to preclinical models to test new chemical entities. The purpose of this review is to examine whether an empirically derived behavioral screen for antidepressant drugs may screen for compounds, at least in part, by modulating an impulsive biasing of responding and altered decision making. The differential-reinforcement-of-low-rate (DRL) 72-second schedule is an operant schedule with a documented fidelity for discriminating antidepressant drugs from nonantidepressant drugs. However, a theoretical basis for this empirical relationship has been lacking. Therefore, this review will discuss whether response bias toward impulsive behavior may be a critical screening characteristic of DRL behavior requiring long inter-response times to obtain rewards. This review will compare and contrast DRL behavior with the five-choice serial reaction time task, a test specifically designed for assessing motoric impulsivity, with respect to psychopharmacological testing and the neural basis of distributed macrocircuits underlying these tasks. This comparison suggests that the existing empirical basis for the DRL 72-second schedule as a pharmacological screen for antidepressant drugs is complemented by a novel hypothesis that altering impulsive response bias for rodents trained on this operant schedule is a previously unrecognized theoretical cornerstone for this screening paradigm.

The US Food and Drug Administration (FDA) considers the development of abuse-deterrent formulations of solid oral dosage forms a public health priority and has outlined a series of premarket studies that should be performed prior to submitting an application to the Agency. Category 1 studies are performed to characterize whether the abuse-deterrent properties of a new formulation can be easily defeated. Study protocols are designed to evaluate common abuse patterns of prescription medications as well as more advanced methods that have been reported on drug abuse websites and forums. Because FDA believes Category 1 testing should fully characterize the abuse-deterrent characteristics of an investigational formulation, Category 1 testing is time consuming and requires specialized laboratory resources as well as advanced knowledge of prescription medication abuse. Recent Advisory Committee meetings at FDA have shown that Category 1 tests play a critical role in FDA's evaluation of an investigational formulation. In this article, we will provide a general overview of the methods of manipulation and routes of administration commonly utilized by prescription drug abusers, how those methods and routes are evaluated in a laboratory setting, and discuss data intake, analysis, and reporting to satisfy FDA's Category 1 testing requirements.

Traditionally, urine drug testing (UDT) in the correctional population (both prison and community corrections) has been infrequent, is scheduled, and has a high possibility of delayed results. Of practical relevance is that scheduled testing is ineffective for identifying drug misuse. Of ethical relevance is that consequences of positive scheduled tests can be unpredictable-in the form of overly severe punishment or a lack of treatment options-and that the scheduled testing paradigm is a poor way to change behaviors. More innovative programs now use a UDT paradigm with more frequent, random testing providing rapid results and certain, swift consequences and addiction treatment when warranted or requested. Studies have shown these new programs-the foundation of which is frequent, random UDTs-to significantly reduce drug use, criminal recidivism, and incarceration. © 2017 American Medical Association.

Administration of corazole into animals led to a decrease in content of NAD and gamma-aminobutyric acid (GABA) in brain. Under these conditions, binding of 14 C-GABA was increased and its liberation was inhibited in the synaptosomes of the brain cortex. Additional administration of incotinamide, accompanied by considerable increase in content of NAD and GABA, caused a decrease in accumulation of exogenous GABA in the synaptosomes and removed the effects produced by the convulsant agent. Kinetics of 14 C-GABA binding in the presence of NAD demonstrated that the more effective inhibition of the binding occurred in the animals treated with the convulsant drug. NAD appears to affect the GABA-ergic transmission at the postsynaptic level

in the drug half-life demonstrated that the presystemic extraction of tretinoin is the main cause of the marked decline in plasma drug exposure. The favourable pharmacokinetic profile of tretinoin obtained by an intermittent regimen, 1 week on/1 week off therapy (vs continuous administration), suggests that such a therapeutic schedule is the most appropriate for the assessment of clinical efficacy in those pathologies in which its use is suitable.

Identification of abuse and frequency patterns of stimulant designer drugs (SDDs) provides important information for their risk assessment and legislative control. In the present study urine and/or blood samples of suspected drug users in criminal cases were analysed by GC-MS for 38 SDDs, and for the most frequent illicit and psychoactive licit drugs in Hungary. Between July 2012 and June 2013, 2744 suspected drug users were sampled in Budapest and during 2012 and 2013, 774 persons were sampled in South-East Hungary (Csongrád County - neighbour the Romanian and Serbian borders). In Budapest 71.4% of cases, and in South-East Hungary 61% of cases were positive for at least one substance. Pentedrone was the most frequent SDD in both regions; however, the frequency distribution of the remaining drugs was highly diverse. SDDs were frequently present in combination with other drugs - generally with amphetamine or other stimulants, cannabis and/or benzodiazepines. The quarterly distribution of positive samples indicated remarkable seasonal changes in the frequency and pattern of consumption. Substances placed on the list of illicit drugs (mephedrone, 4-fluoro-amphetamine, MDPV, methylone, 4-MEC) showed a subsequent drop in frequency and were replaced by other SDDs (pentedrone, 3-MMC, methiopropamine, etc.). Newly identified compounds from seized materials were added to the list of new psychoactive substances ("Schedule C"). While the risk assessment of substances listed in Schedule C has to be performed within 2 years after scheduling, continuous monitoring of their presence and frequency among drug users is essential. In summary, our results suggest which substances should be dropped from the list of SDDs measured in biological samples; while the appearance of new substances from seized materials indicate the need for developing adequate standard analytical methods.

Schedule Matters: Understanding the Relationship between Schedule Delays and Costs on Overruns
Majerowicz, Walt; Shinn, Stephen A.
2016-01-01
This paper examines the relationship between schedule delays and cost overruns on complex projects. It is generally accepted by many project practitioners that cost overruns are directly related to schedule delays. But what does "directly related to" actually mean? Some reasons or root causes for schedule delays and associated cost overruns are obvious, if only in hindsight. For example, unrealistic estimates, supply chain difficulties, insufficient schedule margin, technical problems, scope changes, or the occurrence of risk events can negatively impact schedule performance. Other factors driving schedule delays and cost overruns may be less obvious and more difficult to quantify. Examples of these less obvious factors include project complexity, flawed estimating assumptions, over-optimism, political factors, "black swan" events, or even poor leadership and communication. Indeed, is it even possible the schedule itself could be a source of delay and subsequent cost overrun? Through literature review, surveys of project practitioners, and the authors' own experience on NASA programs and projects, the authors will categorize and examine the various factors affecting the relationship between project schedule delays and cost growth. The authors will also propose some ideas for organizations to consider to help create an awareness of the factors which could cause or influence schedule delays and associated cost growth on complex projects.

MODELING OF TARGETED DRUG DELIVERY PART II. MULTIPLE DRUG ADMINISTRATION
Directory of Open Access Journals (Sweden)
A. V. Zaborovskiy
2017-01-01
Full Text Available In oncology practice, despite significant advances in early cancer detection, surgery, radiotherapy, laser therapy, targeted therapy, etc., chemotherapy is unlikely to lose its relevance in the near future. In this context, the development of new antitumor agents is one of the most important problems of cancer research. In spite of the importance of searching for new compounds with antitumor activity, the possibilities of the “old” agents have not been fully exhausted. Targeted delivery of antitumor agents can give them a “second life”. When developing new targeted drugs and their further introduction into clinical practice, the change in their pharmacodynamics and pharmacokinetics plays a special role. The paper describes a pharmacokinetic model of the targeted drug delivery. The conditions under which it is meaningful to search for a delivery vehicle for the active substance were described. Primary screening of antitumor agents was undertaken to modify them for the targeted delivery based on underlying assumptions of the model.

Groups of rats were given a chronic history of drinking cocaine solutions of different concentrations in daily, 3-h schedule induced polydipsia sessions. Animals failed to develop a preference for cocaine solution to concurrently presented water. Schedule-induction conditions were maintained, and the animals were divided into separate groups, drinking either cocaine or lidocaine placed in a highly acceptable vehicle (glucose-saccharin solution). Animals preferred their respective drug solutions to concurrently presented water, and these preferences remained stable after the glucose-saccharin vehicle was gradually faded to water, leaving only cocaine or lidocaine, respectively, in the solution. Thus a stable preference for drug solution to water could be instituted in rats for either cocaine or lidocaine solution (putative reinforcing and nonreinforcing agents, respectively) given an appropriate associative history, with high intakes maintained by schedule-induction. Conditions sufficient for the initiation of an oral preference and high intake for a putatively reinforcing drug cannot be assumed to occur owing to the drug's reinforcing property in the absence of demonstrating the ineffectiveness of an appropriate negative control substance.

Determining the optimal and effective scheme for administrating the chemotherapy agents in breast cancer is the main goal of this scientific research. The most important issue here is the amount of drug or radiation administrated in chemotherapy and radiotherapy for increasing patient's survival. This is because in these cases, the therapy not only kills the tumor cells, but also kills some of the healthy tissues and causes serious damages. In this paper we investigate optimal drug scheduling effect for breast cancer model which consist of nonlinear ordinary differential time-delay equations. In this paper, a mathematical model of breast cancer tumors is discussed and then optimal control theory is applied to find out the optimal drug adjustment as an input control of system. Finally we use Sensitivity Approach (SA) to solve the optimal control problem. The goal of this paper is to determine optimal and effective scheme for administering the chemotherapy agent, so that the tumor is eradicated, while the immune systems remains above a suitable level. Simulation results confirm the effectiveness of our proposed procedure. In this paper a new scheme is proposed to design a therapy protocol for chemotherapy in Breast Cancer. In contrast to traditional pulse drug delivery, a continuous process is offered and optimized, according to the optimal control theory for time-delay systems.

Full Text Available Depression has been associated with drug consumption, including heavy or problematic cannabis use. According to an animal model of depression and substance use disorder comorbidity, we combined the olfactory bulbectomy model of depression with intravenous drug self-administration procedure to verify whether depressive-like rats displayed higher voluntary intake of the CB1 receptor agonist WIN55,212-2 (WIN, 12.5 µg/kg/infusion. To this aim, olfactory-bulbectomized (OBX and sham-operated (SHAM Lister Hooded rats were allowed to self-administer WIN by lever-pressing under a continuous (FR-1 schedule of reinforcement in 2h daily sessions. Data showed that both OBX and SHAM rats developed stable WIN intake; yet, responses in OBX were constantly higher than in SHAM rats soon after the first week of training. In addition, OBX rats took significantly longer to extinguish the drug-seeking behaviour after vehicle substitution. Acute pre-treatment with serotonin 5HT1B receptor agonist, CGS-12066B (2.5-10 mg/kg, did not significantly modify WIN intake in OBX and SHAM Lister Hooded rats. Furthermore, acute pre-treatment with CGS-12066B (10 and 15 mg/kg did not alter responses in parallel groups of OBX and SHAM Sprague Dawley rats self-administering methamphetamine under higher (FR-2 reinforcement schedule with nose-poking as operandum. Finally, dopamine levels in the nucleus accumbens of OBX rats did not increase in response to a WIN challenge, as in SHAM rats, indicating a dopaminergic dysfunction in bulbectomized rats. Altogether, our findings suggest that a depressive state may alter cannabinoid CB1 receptor agonist-induced brain reward function and that a dopaminergic rather than a 5-HT1B mechanism is likely to underlie enhanced WIN self-administration in OBX rats.

Kotamaki, M
The goal during the last few months has been to freeze and baseline as much as possible the schedules of various ATLAS systems and activities. The main motivations for the re-baselining of the schedules have been the new LHC schedule aiming at first collisions in early 2006 and the encountered delays in civil engineering as well as in the production of some of the detectors. The process was started by first preparing a new installation schedule that takes into account all the new external constraints and the new ATLAS staging scenario. The installation schedule version 3 was approved in the March EB and it provides the Ready For Installation (RFI) milestones for each system, i.e. the date when the system should be available for the start of the installation. TCn is now interacting with the systems aiming at a more realistic and resource loaded version 4 before the end of the year. Using the new RFI milestones as driving dates a new summary schedule has been prepared, or is under preparation, for each system....

Anticancer drugs during pregnancy.
Miyamoto, Shingo; Yamada, Manabu; Kasai, Yasuyo; Miyauchi, Akito; Andoh, Kazumichi
2016-09-01
Although cancer diagnoses during pregnancy are rare, they have been increasing with the rise in maternal age and are now a topic of international concern. In some cases, the administration of chemotherapy is unavoidable, though there is a relative paucity of evidence regarding the administration of anticancer drugs during pregnancy. As more cases have gradually accumulated and further research has been conducted, we are beginning to elucidate the appropriate timing for the administration of chemotherapy, the regimens that can be administered with relative safety, various drug options and the effects of these drugs on both the mother and fetus. However, new challenges have arisen, such as the effects of novel anticancer drugs and the desire to bear children during chemotherapy. In this review, we outline the effects of administering cytotoxic anticancer drugs and molecular targeted drugs to pregnant women on both the mother and fetus, as well as the issues regarding patients who desire to bear children while being treated with anticancer drugs. © The Author 2016.

Human factoring administrative procedures
International Nuclear Information System (INIS)
Grider, D.A.; Sturdivant, M.H.
1991-01-01
In nonnuclear business, administrative procedures bring to mind such mundane topics as filing correspondence and scheduling vacation time. In the nuclear industry, on the other hand, administrative procedures play a vital role in assuring the safe operation of a facility. For some time now, industry focus has been on improving technical procedures. Significant efforts are under way to produce technical procedure requires that a validated technical, regulatory, and administrative basis be developed and that the technical process be established for each procedure. Producing usable technical procedures requires that procedure presentation be engineered to the same human factors principles used in control room design. The vital safety role of administrative procedures requires that they be just as sound, just a rigorously formulated, and documented as technical procedures. Procedure programs at the Tennessee Valley Authority and at Boston Edison's Pilgrim Station demonstrate that human factors engineering techniques can be applied effectively to technical procedures. With a few modifications, those same techniques can be used to produce more effective administrative procedures. Efforts are under way at the US Department of Energy Nuclear Weapons Complex and at some utilities (Boston Edison, for instance) to apply human factors engineering to administrative procedures: The techniques being adapted include the following

To determine the risk factors and rate of medication administration error (MAE) alerts by analyzing large-scale medication administration data and related error logs automatically recorded in a closed-loop medication administration system using radio-frequency identification and barcodes. The subject hospital adopted a closed-loop medication administration system. All medication administrations in the general wards were automatically recorded in real-time using radio-frequency identification, barcodes, and hand-held point-of-care devices. MAE alert logs recorded during a full 1 year of 2012. We evaluated risk factors for MAE alerts including administration time, order type, medication route, the number of medication doses administered, and factors associated with nurse practices by logistic regression analysis. A total of 2 874 539 medication dose records from 30 232 patients (882.6 patient-years) were included in 2012. We identified 35 082 MAE alerts (1.22% of total medication doses). The MAE alerts were significantly related to administration at non-standard time [odds ratio (OR) 1.559, 95% confidence interval (CI) 1.515-1.604], emergency order (OR 1.527, 95%CI 1.464-1.594), and the number of medication doses administered (OR 0.993, 95%CI 0.992-0.993). Medication route, nurse's employment duration, and working schedule were also significantly related. The MAE alert rate was 1.22% over the 1-year observation period in the hospital examined in this study. The MAE alerts were significantly related to administration time, order type, medication route, the number of medication doses administered, nurse's employment duration, and working schedule. The real-time closed-loop medication administration system contributed to improving patient safety by preventing potential MAEs. Copyright © 2016 John Wiley & Sons, Ltd.

The kinetics in rats was studied of the tranquilizer noroxyclothepine (8-chloro-10-(4-hydroxyethyl)piperazino-10,11-dihydrobenzo(b,f)-thiepine). The drug was labelled with carbon 14 and the kinetics of the drug was investigated after oral and i.v. administration. It was found that over 4 days, 88 to 99% of radioactivity was excreted in feces and 5.5 to 6% in the urine, this for both ways of administration. Following oral administration, 50% of radioactivity was eliminated from the organism within 27 hours while following i.v. administration, the elimination took 38 hours. (L.O.)

Full Text Available ABSTRACT The aim of this study was to investigate the epidemiological characteristics, antigenic profile, perceptions, attitudes and practices of individuals who have been systematically non-compliant in mass drug administration (MDA campaigns targeting lymphatic filariasis, in the municipality of Olinda, State of Pernambuco, Northeastern Brazil. A pretested questionnaire was used to obtain information on socioenvironmental demographics, perceptions of lymphatic filariasis and MDA, and reasons for systematic noncompliance with treatment. A rapid immunochromatographic test (ICT was performed during the survey to screen for filariasis. It was found that the survey subjects knew about filariasis and MDA. Filariasis was identified as a disease (86.2% and 74.4% associated it with the presence of swelling in the legs. About 80% knew about MDA, and the main source of information was healthcare workers (68.3%. For men the main reasons for systematic noncompliance with MDA were that “the individual had not received the medication” (p=0.03 and for women “the individual either feared experiencing adverse reactions”. According to the ICT, the prevalence of lymphatic filariasis was 2%. The most important causes of systematic noncompliance were not receiving the drug and fear of side-effects. For successful implementation of MDA programs, good planning, educational campaigns promoting the benefits of MDA, adoption of measures to minimize the impact of adverse effects and improvement of drug distribution logistics are needed.

Full Text Available Increasing evidence focuses on acetaldehyde (ACD as the mediator of the rewarding and motivational properties of ethanol. Indeed, ACD stimulates dopamine release in the nucleus accumbens and it is self-administered under different conditions. Besides the dopaminergic transmission, the endocannabinoid system has been reported to play an important role in ethanol central effects, modulating primary alcohol rewarding effect, drug-seeking and relapse behaviour. Drug motivational properties are highlighted in operant paradigms which include response-contingent punishment, a behavioural equivalent of compulsive drug use despite adverse consequences.The aim of this study was thus to characterize ACD motivational and rewarding properties employing an operant-conflict paradigm in which rats, trained to lever press in order to get ACD solution (0.9%, undergo extinction, reinstatement and conflict sessions, according to a modified Geller-Seifter procedur. Furthermore the role played by CB1 receptor system in modulating ACD-induced effects were investigated through the administration of CB1 receptor antagonist, AM281 (1 mg/kg, i.p. during the extinction-, relapse- and conflict experiments.Our results indicate that ACD is able to induce and maintain an operant behaviour, a high number of responses during extinction, an increase in the lever presses during the reinstatement phase, and a higher emission of punished responses during the conflict experiments, when compared to controls.The administration of AM281 is able to decrease ACD-seeking behaviour during extinction, the number of lever presses during reinstatement and to strongly decrease the punished responses for ACD. Our data strengthen the idea that ACD may be responsible for the central effects of ethanol, and pinpoint at the CB1 system as one of the neural substrates underlying its addictive properties.

To analyze the Adverse Events Reporting System (AERS) database of the Food and Drug Administration (FDA), investigating the characteristics of pediatric adverse drug reactions (ADRs) and describing the effective participation of healthcare professionals in the reporting activity. Reports of ADRs were obtained from the FDA website. Only ADRs in pediatric subjects (divided by age, by country and by professional category) were included into the analysis. The drugs suspected as primary cause of the ADRs in pediatric subjects and their principal anatomic group according to the Anatomical Therapeutic Chemical classification system were considered. To classify the ADRs, the Medical Dictionary for Regularity Activities terminology was adopted. Between 2008 and 2012, FDA collected 113,077 ADRs in pediatric patients. Of the total pediatric ADR reports, those performed by medical doctors were 32%, followed by consumers (26%) and healthcare professionals (25%). Most of the ADR reports were related to the adolescent group (39%). Healthcare professionals resulted the category with the highest rate of ADR reports in neonates and infants. Drugs acting on nervous system and antineoplastic/immunomodulating agents were the most involved the pediatric ADR reports. Pyrexia, convulsion, vomiting and accidental overdose were the reactions more reported both from healthcare professionals and medical doctors. The present study describes the pediatric ADR reports of the FDA database through healthcare professional's perspective, describing the various aspects of pediatric pharmacovigilance.

Full Text Available Background: Mass drug administration (MDA means once-in-a-year administration of diethyl carbamazine (DEC tablet to all people (excluding children under 2 years, pregnant women and severely ill persons in identified endemic areas. It aims at cessation of transmission of lymphatic filariasis. Objective: What has been the coverage and compliance of MDA in Gujarat during the campaign in December 2006? Study Design: Cross-sectional population based house-to-house visit. Setting: Urban and rural areas in Gujarat identified as endemic for filariasis where MDA 2006 was undertaken. Study Variables: Exploratory - Rural and urban districts; Outcome - coverage, compliance, actual coverage, side effects. Analysis: Percentage and proportions. Results: Twenty-six clusters, each comprising 32 households from six endemic districts, yielded an eligible population of 4164. The coverage rate was 85.2% with variation across different areas. The compliance with drug ingestion was 89% with a gap of 11% to be targeted by intensive IEC. The effective coverage (75.8% was much below the target (85%. Side effects of DEC were minimum, transient and drug-specific. Overall coverage was marginally better in rural areas. The causes of poor coverage and compliance have been discussed and relevant suggestions have been made.

The aim of the present work was to implement the kinetics of cisplatin into a previously developed tumour growth model and to simulate the combined cisplatin-radiotherapy treatment with the emphasis on time sequencing and scheduling of drug and radiation. An investigation into whether the effect of cisplatin-radiation is determined by independent cell kill or by cisplatin-produced radiosensitization was also undertaken. It was shown that cisplatin administered before radiation conferred similar tumour control to the post-radiation sequencing of the drug. The killing effect of the combined modality treatment on tumour increased with the increase in cell recruitment. Furthermore, the individual cell kill produced by the two cytotoxins led to an additive only tumour response when the treatments were given concurrently, suggesting that for a synergistic effect, cisplatin must potentiate the effect of radiation, through the radiosensitizing mechanisms addressed in the literature. It was concluded that the optimal timing of cisplatin should be close to radiation. The model showed that daily administration of cisplatin led to a 35% improvement of tumour control as compared to radiation alone, while weekly cisplatin has improved radiotherapy by only 6%

It is important to evaluate the potential of drug hypersensitivity as well as other adverse effects during the preclinical stage of the drug development process, but validated methods are not available yet. In the present study we examined whether it would be possible to develop a new predictive model of drug hypersensitivity using Brown Norway (BN) rats. As representative drugs with hypersensitivity potential in humans, phenytoin (PHT), carbamazepine (CBZ), amoxicillin (AMX), and sulfamethoxazole (SMX) were orally administered to BN rats for 28 days to investigate their effects on these animals by examinations including observation of clinical signs, hematology, determination of serum IgE levels, histology, and flow cytometric analysis. Skin rashes were not observed in any animals treated with these drugs. Increases in the number of circulating inflammatory cells and serum IgE level did not necessarily occur in the animals treated with these drugs. However, histological examination revealed that germinal center hyperplasia was commonly induced in secondary lymphoid organs/tissues in the animals treated with these drugs. In cytometric analysis, changes in proportions of lymphocyte subsets were noted in the spleen of the animals treated with PHT or CBZ during the early period of administration. The results indicated that the potential of drug hypersensitivity was identified in BN rat by performing histological examination of secondary lymphoid organs/tissues. Data obtained herein suggested that drugs with hypersensitivity potential in humans gained immune reactivity in BN rat, and the germinal center hyperplasia induced by administration of these drugs may serve as a predictive biomarker for drug hypersensitivity occurrence. - Highlights: • We tested Brown Norway rats as a candidate model for predicting drug hypersensitivity. • The allergic drugs did not induce skin rash, whereas D-penicillamine did so in the rats. • Some of allergic drugs increased

The U.S. food and drug administration's dosimetry program
International Nuclear Information System (INIS)
Baratta, E.
2005-01-01
Full text: The U. S. Public Health Service's (PHS) Food and Drug Administration (FDA) (part of the PHS) has had a Dosimetry Program at the Winchester Engineering and Analytical Center (WEAC) (formerly the Northeastern Radiological Health Laboratory). This Dosimetry Program has been in place since 1961. In 1967 it was augmented by the construction of a Whole Body Counter at WEAC for measuring internal dose. The FDA's Center for Medical Devices and Radiological Health had been handling these dosimeters since 1961 and in 2000 the WEAC took over total responsibility for this program for the FDA's Office of Regulatory affairs. This program was originally setup for the radiation workers (analysts and support personnel) and later included investigators personnel working in the medical and dental x-ray field. The field laboratories began using radionuclides in 1972 and were also issued radiation dosimeters. Investigators station at border import station alter 2003 were issued as well as radiation pages as a precaution when checking imported food and other FDA regulated products. This paper will discuss the results of radiation exposure received by analyst (including whole body measurements) at WEAC and field laboratories. Also discussed will be exposures to investigators in the medical and dental field. The exposure to the investigators at the import border stations will be included even though they have not been carrying dosimeters for slightly more than a year. In general, the exposures have been well below the Nuclear Regulatory Commission regulations for radiation workers. (author)

Constraint-based scheduling applying constraint programming to scheduling problems
Baptiste, Philippe; Nuijten, Wim
2001-01-01
Constraint Programming is a problem-solving paradigm that establishes a clear distinction between two pivotal aspects of a problem: (1) a precise definition of the constraints that define the problem to be solved and (2) the algorithms and heuristics enabling the selection of decisions to solve the problem. It is because of these capabilities that Constraint Programming is increasingly being employed as a problem-solving tool to solve scheduling problems. Hence the development of Constraint-Based Scheduling as a field of study. The aim of this book is to provide an overview of the most widely used Constraint-Based Scheduling techniques. Following the principles of Constraint Programming, the book consists of three distinct parts: The first chapter introduces the basic principles of Constraint Programming and provides a model of the constraints that are the most often encountered in scheduling problems. Chapters 2, 3, 4, and 5 are focused on the propagation of resource constraints, which usually are responsibl...

Scheduling for decommissioning projects
International Nuclear Information System (INIS)
Podmajersky, O.E.
1987-01-01
This paper describes the Project Scheduling system being employed by the Decommissioning Operations Contractor at the Shippingport Station Decommissioning Project (SSDP). Results from the planning system show that the project continues to achieve its cost and schedule goals. An integrated cost and schedule control system (C/SCS) which uses the concept of earned value for measurement of performance was instituted in accordance with DOE orders. The schedule and cost variances generated by the C/SCS system are used to confirm management's assessment of project status. This paper describes the types of schedules and tools used on the SSDP project to plan and monitor the work, and identifies factors that are unique to a decommissioning project that make scheduling critical to the achievement of the project's goals. 1 fig

The erythro- and threoform of p-hydroxynorephedrine belong to the group of drugs affecting the course of hypertensive disease. For pharmacological studies both forms were labelled with 3 H radionuclide on the benzene ring. 90% of radioactivity was concentrated in the ortho positions with regard to the hydroxyl, 10% in the meta position. After the administration of the labelled drug to rats, rapid absorption occurs and radioactivity is eliminated from the organism, especially in the urine. Three radioactive substances were found in the urine of experimental animals. A substance with properties corresponding to those of the administered drug prevailed. The highest levels of radioactivity in the tissues were found after intravenous administration as early as after 5 minutes after administration, 15 minutes after subcutaneous administration. It was found that p-hydroxynorephedrine significantly restricted the detainment of labelled noradrenaline-7- 3 H in the tissues of premedicated animals. (author)

Pigeons' key pecks produced food under second-order schedules of token reinforcement, with light-emitting diodes serving as token reinforcers. In Experiment 1, tokens were earned according to a fixed-ratio 50 schedule and were exchanged for food according to either fixed-ratio or variable-ratio exchange schedules, with schedule type varied across conditions. In Experiment 2, schedule type was varied within sessions using a multiple schedule. In one component, tokens were earned according to a fixed-ratio 50 schedule and exchanged according to a variable-ratio schedule. In the other component, tokens were earned according to a variable-ratio 50 schedule and exchanged according to a fixed-ratio schedule. In both experiments, the number of responses per exchange was varied parametrically across conditions, ranging from 50 to 400 responses. Response rates decreased systematically with increases in the fixed-ratio exchange schedules, but were much less affected by changes in the variable-ratio exchange schedules. Response rates were consistently higher under variable-ratio exchange schedules than tinder comparable fixed-ratio exchange schedules, especially at higher exchange ratios. These response-rate differences were due both to greater pre-ratio pausing and to lower local rates tinder the fixed-ratio exchange schedules. Local response rates increased with proximity to food under the higher fixed-ratio exchange schedules, indicative of discriminative control by the tokens.

The GERRY scheduling system developed by NASA Ames with assistance from the Lockheed Space Operations Company, and the Lockheed Artificial Intelligence Center, uses a method called constraint-based iterative repair. Using this technique, one encodes both hard rules and preference criteria into data structures called constraints. GERRY repeatedly attempts to improve schedules by seeking repairs for violated constraints. The system provides a general scheduling framework which is being tested on two NASA applications. The larger of the two is the Space Shuttle Ground Processing problem which entails the scheduling of all the inspection, repair, and maintenance tasks required to prepare the orbiter for flight. The other application involves power allocation for the NASA Ames wind tunnels. Here the system will be used to schedule wind tunnel tests with the goal of minimizing power costs. In this paper, we describe the GERRY system and its application to the Space Shuttle problem. We also speculate as to how the system would be used for manufacturing, transportation, and military problems.
