  1. Influence of radiation treatment on pharmaceuticals and adjuvants: A literature study. Pt. 9. Supplement

    International Nuclear Information System (INIS)

    Sterilization of medical aid articles (e.g. catheters, one-way syringes) with ionizing radiation is a successful practice in many countries. During recent years, the results from numerous experiments of radiosterillization of pharmaceuticals and adjuvants have likewise been published. Experience has shown that radiation treatment, in many cases, is leading to transformations of the irradiated substances. In the present part IX of the bibliographic study on the influence of radiation treatment on pharmaceuticals and adjuvants the results of experiments on ca. 80 substances from 36 different sources have been evaluated. In all parts of the study results of about 560 experiments on 360 substances from 176 different sources are present. (orig.)

  2. Sterilization of pharmaceutical ingredients, adjuvants and packaging materials by gamma radiation

    International Nuclear Information System (INIS)

    Different antibiotics, pharmaceutical ingredients, adjuvants and packaging materials were treated with gamma radiation of 0.5-2.8x106 rad using 60Co source. The effect of 2.5-2.8x106 rad on antibiotics, carbohydrates, citiric acid is a discoloration in some degree. The change of colour was accompanied by a decrease of activity of oxytetracycline hydrochloride and tobramycin sulphate, a decrease of viscosity of starch, and an increase of the reducing rate of saccharose and lactose. The sterility of substances contaminated by 103 organisms per gram was obtained by a dose of 0.5x106 rad. There was no discoloration and no changes were observed in the examined parameter of these materials. The examined aluminium, rubber and plastic packaging materials suffered no changes. (author)

    2006-04-12

    New and improved vaccines and delivery systems are increasingly being developed for prevention, treatment and diagnosis of human diseases. Prior to their use in humans, all new biological products must undergo pre-clinical evaluation. These pre-clinical studies are important not only to establish the biological properties of the material and to evaluate its possible risk to the public, but also to plan protocols for subsequent clinical trials from which safety and efficacy can be evaluated. For vaccines, evaluation in pre-clinical studies is particularly important as information gained may also contribute to identifying the optimum composition and formulation process and provide an opportunity to develop suitable indicator tests for quality control. Data from pre-clinical and laboratory evaluation studies, which continue during clinical studies, is used to support an application for marketing authorisation. Addition of a new adjuvant and exploration of new delivery systems for vaccines presents challenges to both manufacturers and regulatory authorities. Because no adjuvant is licensed as a medicinal product in its own right, but only as a component of a particular vaccine, pre-clinical and appropriate toxicology studies need to be designed on a case-by-case basis to evaluate the safety profile of the adjuvant and adjuvant/vaccine combination. Current regulatory requirements for the pharmaceutical and pre-clinical safety assessment of vaccines are insufficient and initiatives are in place to develop more specific guidelines for evaluation of adjuvants in vaccines.

    2012-10-01

    Allergen-specific immunotherapy is currently performed via either the subcutaneous or sublingual routes as a treatment for type I (IgE dependent) allergies. Aluminum hydroxide or calcium phosphate are broadly used as adjuvants for subcutaneous allergy vaccines, whereas commercial sublingual vaccines rely upon high doses of aqueous allergen extracts in the absence of any immunopotentiator. Adjuvants to be included in the future in products for allergen specific immunotherapy should ideally enhance Th1 and CD4+ regulatory T cell responses. Imunomodulators impacting dendritic or T cell functions to induce IL10, IL12 and IFNγ production are being investigated in preclinical allergy models. Such candidate adjuvants encompass synthetic or biological immunopotentiators such as glucocorticoids, 1,25-dihydroxy vitamin D3, selected probiotic strains (e.g., Lactobacillus and Bifidobacterium species) as well as TLR2 (Pam3CSK4), TLR4 (monophosphoryl lipid A, synthetic lipid A analogs) or TLR9 (CpGs) ligands. Furthermore, the use of vector systems such as mucoadhesive particules, virus-like particles or liposomes are being considered to enhance allergen uptake by tolerogenic antigen presenting cells present in mucosal tissues.

    In the early history of psychopharmacology, the prospect of developing technologically sophisticated drugs to alleviate human ills was surrounded with a fervor that could be described as religious. This paper explores the subsequent history of the development of psychopharmacological agents, focusing on the ambivalent position of both the industry and its employees. Based on interviews with retired pharmaceutical employees who were active in the industry in the 1950s and 1960s when the major breakthroughs were made in the development of MAOIs and SSRIs, the paper explores the initial development of educational materials for use in sales campaigns. In addition, based on interviews with current employees in pharmaceutical sales and marketing, the paper describes the complex perspective of contemporary pharmaceutical employees who must live surrounded by the growing public vilification of the industry as rapacious and profit hungry and yet find ways to make their jobs meaningful and dignified. The paper will contribute to the understudied problem of how individuals function in positions that require them to be part of processes that on one description constitute a social evil, but on another, constitute a social good.

    2011-01-01

    The role for adjuvants in human vaccines has been a matter of vigorous scientific debate, with the field hindered by the fact that for over 80 years, aluminum salts were the only adjuvants approved for human use. To this day, alum-based adjuvants, alone or combined with additional immune activators, remain the only adjuvants approved for use in the USA. This situation has not been helped by the fact that the mechanism of action of most adjuvants has been poorly understood. A relative lack of resources and funding for adjuvant development has only helped to maintain alum’s relative monopoly. To seriously challenge alum’s supremacy a new adjuvant has many major hurdles to overcome, not least being alum’s simplicity, tolerability, safety record and minimal cost. Carbohydrate structures play critical roles in immune system function and carbohydrates also have the virtue of a strong safety and tolerability record. A number of carbohydrate compounds from plant, bacterial, yeast and synthetic sources have emerged as promising vaccine adjuvant candidates. Carbohydrates are readily biodegradable and therefore unlikely to cause problems of long-term tissue deposits seen with alum adjuvants. Above all, the Holy Grail of human adjuvant development is to identify a compound that combines potent vaccine enhancement with maximum tolerability and safety. This has proved to be a tough challenge for many adjuvant contenders. Nevertheless, carbohydrate-based compounds have many favorable properties that could place them in a unique position to challenge alum’s monopoly over human vaccine usage. PMID:21506649

    The microbiological quality of many raw materials used in the manufacture of pharmaceuticals and adjuvants often fails to meet the standards set by the pharmaceutical industry. Raw materials of biological provenience are particularly susceptible to contamination. This work describes the present situation regarding the microbial load of corn starch. Given the accepted microbiological criteria, irradiation treatment is proposed as integral to Good Pharmaceutical Manufacturing Practice (GPMP). The use of total viable count as a guide for specifying microbial limits for non-sterile materials is supported. Criteria for the choice of dose are discussed. (author)

    Full Text Available With an incidence that is increasing at 2–5% per year, cutaneous melanoma is an international scourge that disproportionately targets young individuals. Despite much research, the treatment of advanced disease is still quite challenging. Immunotherapy with high-dose interferon-α2b or interleukin-2 benefits a select group of patients in the adjuvant and metastatic settings, respectively, with significant attendant toxicity. Advances in the biology of malignant melanoma and the role of immunomodulatory therapy have produced advances that have stunned the field. In this paper, we review the data for the use of interferon-α2b in various dosing ranges, vaccine therapy, and the role of radiotherapy in the adjuvant setting for malignant melanoma. Recent trials in the metastatic setting using anticytoxic T-lymphocyte antigen-4 (anti-CTLA-4 monoclonal antibody therapy and BRAF inhibitor therapy have demonstrated clear benefit with prolongation of survival. Trials investigating combinations of these novel agents with existing immunomodulators are at present underway.

    Patients with AJCC Stage IIB and III melanoma have a poor 5-year survival rate which has been the driving force behind attempts to find an effective adjuvant therapy for this stage of disease that would effectively reduce relapse and improve survival. Immunotherapy with bacillus Calmette-Guerin (BCG), Corynebacterium parvum, and levamisole have not been successful in achieving this goal, nor have trials with chemotherapy in the adjuvant setting, including high-dose chemotherapy with autologous bone marrow transplantation. The recent Eastern Cooperative Oncology Group (ECOG) 1684 study showed significant improvement in relapse-free and overall survival with high doses of alpha interferon (IFNalpha) given for 1 year. Lower dosages of IFNalpha have to date been unsuccessful in impacting upon long-term survival. Recent data with vaccines have been encouraging, and the GM2-KLH vaccine is the focus of ongoing intergroup study comparing this treatment with IFNalpha in resected Stage IIB and III melanoma. The various regimens are reviewed in this article. PMID:9588723

    The management of colon and rectal cancer has changed dramatically over the last 25 years. The use of adjuvant therapies has become standard practice in locally advanced (stage Ⅲ and selected stage Ⅱ) colorectal cancer. Improved surgical techniques, chemotherapeutics and radiotherapy are resulting in higher cure rates and the development of agents targeting proliferative and angiogenic pathways offer further promise. Here we explore risk factors for local and distant recurrence after resection of colon and rectal cancer, and the role of adjuvant treatments. Discussion will focus on the evidence base for adjuvant therapies utilised in colorectal cancer, and the treatment of sub-groups such as the elderly and stage Ⅱ disease. The role of adjuvant radiotherapy in rectal cancer in reduction of recurrence will be explored and the role and optimal methods for surveillance post-curative resection with or without adjuvant therapy will also be addressed.

  16. Innate immunity and adjuvants.

    2011-10-12

    Innate immunity was for a long time considered to be non-specific because the major function of this system is to digest pathogens and present antigens to the cells involved in acquired immunity. However, recent studies have shown that innate immunity is not non-specific, but is instead sufficiently specific to discriminate self from pathogens through evolutionarily conserved receptors, designated Toll-like receptors (TLRs). Indeed, innate immunity has a crucial role in early host defence against invading pathogens. Furthermore, TLRs were found to act as adjuvant receptors that create a bridge between innate and adaptive immunity, and to have important roles in the induction of adaptive immunity. This paradigm shift is now changing our thinking on the pathogenesis and treatment of infectious, immune and allergic diseases, as well as cancers. Besides TLRs, recent findings have revealed the presence of a cytosolic detector system for invading pathogens. I will review the mechanisms of pathogen recognition by TLRs and cytoplasmic receptors, and then discuss the roles of these receptors in the development of adaptive immunity in response to viral infection.

    Full Text Available There is no clear consensus on what type of adjuvant therapy should be used for patients with pancreatic cancer. Chemoradiation is the favored treatment modality by many in the United States while gemcitabine based chemotherapy is favored in Europe. Both of these approaches have been shown by large prospective, randomized trials to improve disease free intervals and in some studies overall survival. This year at the American Society of Clinical Oncology (ASCO Gastrointestinal Cancer Symposium, the randomized phase III study presented by Uesaka et al. from Japan (Abstract #145 represents a newer paradigm of oral adjuvant S-1 chemotherapy in place of the traditional standard of care intravenous gemcitabine in terms of prolonging patients’ survival. Another study by Fan et al. (Abstract #269 examined the value of targeted therapy using erlotinib with adjuvant chemoradiation and chemotherapy. We present the summary of these two studies and discuss the potential impact on our clinical practice on this highly lethal cancer.

    We earlier identified a developmental series of seven isoforms/polymorphs of microparticulate inulin by comparing non-covalent bonding strengths. Their pharmaceutical utility lies in the modulation of cellular immunity, exploited as vaccine adjuvants (Advax™) especially for delta inulin (DI). As such particles cannot be sterilized by filtration we explore the effect of (60)Co gamma radiation (GR) on inulin isoforms, particularly DI. Its adjuvant activity and overt physical properties were unaffected by normal GR sterilizing doses (up to 25kGy). Heating irradiated isoform suspensions near their critical dissolution temperature revealed increased solubility deduced to reflect a single lethal event in one component of a multi-component structure. Local oxidative effects of GR on DI were not found. The observed DI loss was almost halved by re-annealing at the critical temperature: surviving inulin chains apparently reassemble into smaller amounts of the original type of structure. Colorimetric tetrazolium assay revealed increases in reducing activity after GR of raw inulin powder, which yielded DI with normal physical properties but only 25% normal recovery yet 4× normal reducing ability, implying final retention of some GR-changed inulin chains. These findings suggest minimal inulin chain cleavage and confirm that GR may be a viable strategy for terminal sterilization of microparticulate inulin adjuvants.

    The history, present status and future prospects of adjuvants application in herbicides were briefly reviewed. Adjuvants can be separated into two groups, activator adjuvants and utility adjuvants. The former directly enhances the efficacy of a herbicide through increasement of herbicide absorption, spreading, cuticular penetration, rainfastness and retention enhancement, and photodegradation of the herbicide can also be decreased. And the latter is utilized for improving application characteristics, behaviors and physical properties of herbicides and reducing or minimizing unwanted side effects on application.

    The outlook for patients with pancreatic cancer has been grim. There have been major advances in the surgical treatment of pancreatic csncer, leading to a drsmatic reduction in post-operative mortality from the development of high volume specialized centres. This stimulated the study of adjuvant and neoadjuvant treatments in pancreatic cancer including chemoradiotherapy and chemotherapy. Initial protocols have been based on the original but rather small GITSG study first reported in 1985. There have been two large European trials totalling over 600 patients (EORTC and ESPAC-1) that do not support the use of chemoradiation as adjuvant therapy. A second major finding from the ESPAC-1 trial (541 patients randomized) was some but not conclusive evidence for a survival benefit associated with chemotherapy. A third major finding from the ESPAC-1 trial was that the quality of life was not affected by the use of adjuvant treatments compared to surgery alone.The ESPAC-3 trial aims to assess the definitive use of adjuvant chemotherapy in a randomized controlled trial of 990 patients.

    High risk surgically resected melanoma is associated with a less than 50% 5-year survival. Adjuvant therapy is an appropriate treatment modality in this setting, and is more likely to be effective as the tumour burden here is small. Clinical observations of spontaneous tumour regressions and a highly variable rate of disease progression suggest a role of the immune system in the natural history of melanoma. Biological agents have therefore been the subjects of numerous adjuvant studies. Early, randomised controlled trials (RCTs) of Bacillus Calmette-Guerin (BCG), levamisole, Corynebacterium parvum, chemotherapy, isolated limb perfusion (ILP), radiotherapy, transfer factor (TF), megestrol acetate and vitamin A yielded largely negative results. Current trials focus on vaccines and the interferons. To date the latter is the only therapy to have shown a significant benefit in the prospective randomised controlled phase III setting. This report represents a systematic review of studies in adjuvant therapy in melanoma. Data from ongoing studies is awaited before a role for adjuvant agents in high risk melanoma is confirmed.

    Adjuvants have been common additions to vaccines to help facilitate vaccine delivery. With advancements in vaccine technology, several adjuvants which activate immune specific responses have emerged. Available data show these adjuvants elicit important immune responses in both healthy and immunocompromised populations, as well as the elderly. Guidelines for the use and licensure of vaccine adjuvants remain under discussion. However, there is a greater understanding of the innate and adaptive immune response, and the realization of the need for immune specific adjuvants appears to be growing. This is a focused review of four adjuvants currently in clinical trial development: ASO4, ASO2A, CPG 7907, and GM-CSF. The vaccines including these adjuvants are highly relevant today, and are expected to reduce the disease burden of cervical cancer, hepatitis B and malaria. PMID:18398303

    Inulin is a flexible oligosaccharide which has been used primarily in food for decades. Recently new applications in the pharmaceutical arena were described. In a previous review (Mensink et al. (2015). Carbohydrate Polymers, 130, 405) we described the physicochemical characteristics of inulin, characteristics which make inulin a highly versatile substance. Here, we review its pharmaceutical applications. Applications of inulin that are addressed are stabilization of proteins, modified drug delivery (dissolution rate enhancement and drug targeting), and lastly physiological and disease-modifying effects of inulin. Further uses of inulin include colon specific drug administration and stabilizing and adjuvating vaccine formulations. Overall, the uses of inulin in the pharmaceutical area are very diverse and research is still continuing, particularly with chemically modified inulins. It is therefore likely that even more applications will be found for this flexible oligosaccharide.

    2007-05-01

    Full Text Available Background: Aluminum salts are common adjuvants in human and animal vaccine preparations. The two adjuvants aluminum phosphate and aluminum hydroxide show acceptable immunoadjuvant properties with many antigens. These two salts have different physicochemical characteristics that make each one suitable for certain antigens. The surface antigen of Hepatitis B (HBsAg has several antigenic epitopes that bind to aluminum adjuvants by a ligand exchange mechanism. Although HBV vaccines using an aluminum hydroxide adjuvant are available, higher antigenicity is needed for the subgroup of people who do not respond sufficiently to the currently available vaccines. Methods: A solution of recombinant HBsAg for making different formulations of vaccines with aluminum phosphate (Adju-Phos® and aluminum hydroxide (Alhydrogel® adjuvants was obtained from Darupakhsh Pharmaceutical Company. The total protein content, antigenicity, and purity of HBsAg solution were determined using BCA, ELISA, and SDS-PAGE methods, respectively. The different formulations were prepared in the lab and administered i.p. to two test groups of Balb/C mice and a third test group received the Engerix vaccine, which is currently available on the market and uses an aluminum hydroxide adjuvant. The control group of animals received the solution without antigen. After 28 days, heart blood samples were collected and serum was separated to determine the antibody titer against HBsAg using an ELISA kit. Results: This study shows that the vaccine formulated with aluminum phosphate exerted more immunogenicity than both the aluminum hydroxide laboratory formulation and the Engerix vaccines. Conclusion: Although the results of our study indicate higher immunogenic properties of the vaccine formulated with the aluminum phosphate adjuvant, complementary experiments are needed to further evaluate the biological properties with respect to effectiveness, adverse effects, product stability and finally

    2016-01-01

    Vaccination is one of the most efficient strategies for the prevention of infectious diseases. Although safer, subunit vaccines are poorly immunogenic and for this reason the use of adjuvants is strongly recommended. Since their discovery in the beginning of the 20th century, adjuvants have been used to improve immune responses that ultimately lead to protection against disease. The choice of the adjuvant is of utmost importance as it can stimulate protective immunity. Their mechanisms of action have now been revealed. Our increasing understanding of the immune system, and of correlates of protection, is helping in the development of new vaccine formulations for global infections. Nevertheless, few adjuvants are licensed for human vaccines and several formulations are now being evaluated in clinical trials. In this review, we briefly describe the most well known adjuvants used in experimental and clinical settings based on their main mechanisms of action and also highlight the requirements for licensing new vaccine formulations.

    2007-01-01

    Vaccines require optimal adjuvants including immunopotentiator and delivery systems to offer long term protection from infectious diseases in animals and man. Initially it was believed that adjuvants are responsible for promoting strong and sustainable antibody responses. Now it has been shown that adjuvants influence the isotype and avidity of antibody and also affect the properties of cell-mediated immunity. Mostly oil emulsions, lipopolysaccharides, polymers, saponins, liposomes, cytokines,ISCOMs (immunostimulating complexes), Freund's complete adjuvant, Freund's incomplete adjuvant, alums, bacterial toxins etc.,are common adjuvants under investigation. Saponin based adjuvants have the ability to stimulate the cell mediated immune system as well as to enhance antibody production and have the advantage that only a low dose is needed for adjuvant activity. In the present study the importance of adjuvants, their role and the effect of saponin in immune system is reviewed.

  3. Synthetic Self-Adjuvanting Glycopeptide Cancer Vaccines

    Science.gov (United States)

    Payne, Richard; McDonald, David; Byrne, Scott

    2015-10-01

    Due to changes in glycosyltransferase expression during tumorigenesis, the glycoproteins of cancer cells often carry highly truncated carbohydrate chains compared to those on healthy cells. These glycans are known as tumor-associated carbohydrate antigens, and are prime targets for use in vaccines for the prevention and treatment of cancer. Herein, we review the state-of-the-art in targeting the immune system towards tumor-associated glycopeptide antigens via synthetic self adjuvanting vaccines, in which the antigenic and adjuvanting moieties of the vaccines are present in the same molecule. The majority of the self-adjuvanting glycopeptide cancer vaccines reported to date employ antigens from mucin 1, a protein which is highly over-expressed and aberrantly glycosylated in many forms of cancer. The adjuvants used in these vaccines predominantly include lipopeptide- or lipoamino acid-based TLR2 agonists, although studies investigating stimulation of TLR9 and TLR4 are also discussed. Most of these adjuvants are highly lipophilic, and, upon conjugation to antigenic peptides, provide amphiphilic vaccine molecules. The amphiphilic nature of these vaccine constructs can lead to the formation of higher-order structures by vaccines in solution, which are likely to be important for their efficacy in vivo.

    Renal cell carcinoma (RCC) is one of the ten most frequent solid tumors worldwide. Recent innovations in the treatment of metastatic disease have led to new therapeutic approaches being investigated in the adjuvant setting. Observation is the only current standard of care after radical nephrectomy, although there is evidence of efficacy of adjuvant use of vaccine among all the strategies used. This article aims to collect published experiences with systemic adjuvant approaches in RCC and to describe the results of past and ongoing phase III clinical trials in this field. We explored all the systemic treatments, including chemotherapy, immunotherapy and targeted drugs while alternative approaches have also been described. Appropriate selection of patients who would benefit from adjuvant therapies remains a crucial dilemma. Although the international guidelines do not actually recommend any adjuvant treatment after radical surgery for RCC, no conclusions have yet been drawn pending the results of the promising ongoing clinical trials with the target therapies. The significant changes that these new drugs have made on advanced disease outcome could represent the key to innovation in terms of preventing recurrence, delaying relapse and prolonging survival after radical surgery for RCC.

    The World Trade Organization's Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) set global minimum standards for the protection of intellectual property, substantially increasing and expanding intellectual-property rights, and generated clear gains for the pharmaceutical industry and the developed world. The question of whether TRIPS generates gains for developing countries, in the form of increased exports, is addressed in this paper through consideration of the importance of pharmaceuticals in health-care trade, outlining the essential requirements, implications, and issues related to TRIPS, and TRIPS-plus, in which increased restrictions are imposed as part of bilateral free-trade agreements. TRIPS has not generated substantial gains for developing countries, but has further increased pharmaceutical trade in developed countries. The unequal trade between developed and developing countries (ie, exporting and importing high-value patented drugs, respectively) raises the issue of access to medicines, which is exacerbated by TRIPS-plus provisions, although many countries have not even enacted provision for TRIPS flexibilities. Therefore this paper focuses on options that are available to the health community for negotiation to their advantage under TRIPS, and within the presence of TRIPS-plus. PMID:19167054

    Allergen-specific immunotherapy represents a curative treatment of type I allergies. Subcutaneous immunotherapy is conducted with allergens adsorbed on aluminum hydroxide or calcium phosphate particles, whereas sublingual immunotherapy relies on high doses of soluble allergen without any immunopotentiator. There is a potential benefit of adjuvants enhancing regulatory and Th1 CD4+T cell responses during specific immunotherapy. Molecules affecting dendritic cells favor the induction of T regulatory cell and Th1 responses and represent valid candidate adjuvants for allergy vaccines. Furthermore, the interest in viruslike particles and mucoadhesive particulate vector systems, which may better address the allergen(s) to tolerogenic antigen-presenting cells, is documented.

Squalene was used as positive control, as well as MPLA with alum. The immune response was evaluated by a panel of tests, including a hemagglutination inhibition (HAI) test, ELISA for IgG, IgG1, and IgG2a and IFN-γ, IL-2, IL-6 and IL-10 quantification in splenocyte culture supernatant after stimulus with influenza antigen. Immunological memory was evaluated using a 1/10 dose booster 60 days after the first immunization followed by assessment of the response by HAI, IgG ELISA, and determination of the antibody affinity index. The highest increases in HAI, IgG1 and IgG2a titers were obtained with the adjuvant combinations containing vitamin E, or the hydrophilic combinations containing MPLA and alum or B2 and alum. The IgG1/IgG2a ratio indicates that the response to the combination of B2 with alum would have more Th2 character than the combination of MPLA with alum. In an assay to investigate the memory response, a significant increase in HAI titer was observed with a booster vaccine dose at 60 days after immunization with vaccines containing MPLA with alum or B2 with alum. Overall, of the 27 adjuvant combinations, MPLA with alum and B2 with alum were the most promising adjuvants to be evaluated in humans.

    Pancreatic adenocarcinoma is one of the most aggressive human malignancies,ranking 4th among causes for cancer-related death in the Western world including the United States.Surgical resection offers the only chance of cure,but only 15 to 20 percent of cases are potentially resectable at presentation.Different studies demonstrate and confirm that advanced pancreatic cancer is among the most complex cancers to treat and that these tumors are relatively resistant to chemotherapy and radiotherapy.Currently there is no consensus around the world on what constitutes "standard"adjuvant therapy for pancreatic cancer.This controversy derives from several studies,each fraught with its own limitations.Standards of care also vary somewhat with regard to geography and economy,for instance chemo-radiotherapy followed by chemotherapy or vice versa is considered the optimal therapy in North America while chemotherapy alone is the current standard in Europe.Regardless of the efforts in adjuvant and neoadjuvant improved therapy,the major goal to combat pancreatic cancer is to find diagnostic markers,identifying the disease in a pre-metastatic stage and making a curative treatment accessible to more patients.In this review,authors examined the different therapy options for advanced pancreatic patients in recent years and the future directions in adjuvant and neoadjuvant treatments for these patients.

    Research and development (R&D) collaborations represent one approach chosen by the pharmaceutical industry to tackle current challenges posed by declining internal R&D success rates and fading of the blockbuster model. In recent years, a flexible concept to collaborate in R&D has emerged: virtual pharmaceutical companies (VPCs). These differ from other R&D companies, such as biotech start-ups, collaborating with big pharmaceutical companies, because they solely comprise experienced teams of managers. VPCs have only been described anecdotally in literature. Thus, we present here the characteristics of a VPC and suggest how big pharma can leverage the concept of VPCs by introducing five possible modes of collaboration. We find that one mode, investing, is particularly promising for big pharma.

    2012-01-01

    Full Text Available Cytoreductive surgery (CRS and hyperthermic intraperitoneal chemotherapy (HIPEC have been established as treatment options for patients with peritoneal metastases or peritoneal mesothelioma. However, this novel treatment strategy remains associated with a large percentage of local-regional treatment failures. These treatment failures are attributed to the inadequacy of HIPEC to maintain a surgical complete response. Management strategies to supplement CRS and HIPEC are indicated. A simplified approach to the intraoperative placement of an intraperitoneal port for adjuvant bidirectional chemotherapy (ABC was devised. Four different chemotherapy treatment plans were utilized depending upon the primary site of the malignancy. Thirty-one consecutive patients with an intraoperative placement of the intraperitoneal port were available for study. The incidence of adverse events that caused an early discontinuation of the bidirectional chemotherapy occurred in 75% of the 8 patients who had an incomplete cytoreduction and in 0% of patients who had a complete cytoreduction. All of the patients who had complete cytoreduction completed at least 5 of the scheduled 6 bidirectional chemotherapy treatments. Adjuvant bidirectional chemotherapy is possible following a major cytoreductive surgical procedure using a simplified method of intraoperative intraperitoneal port placement.

  18. Adjuvant chemotherapy for soft tissue sarcoma.

    Casali, Paolo G

    2015-01-01

    Adjuvant chemotherapy is not standard treatment in soft tissue sarcoma (STS). However, when the risk of relapse is high, it is an option for shared decision making with the patient in conditions of uncertainty. This is because available evidence is conflicting, even if several randomized clinical trials have been performed for 4 decades and also have been pooled into meta-analyses. Indeed, available meta-analyses point to a benefit in the 5% to 10% range in terms of survival and distant relapse rate. Some local benefit also was suggested by some trials. Placing chemotherapy in the preoperative setting may help gain a local advantage in terms of the quality of surgical margins or decreased sequelae. This may be done within a personalized approach according to the clinical presentation. Attempts to personalize treatment on the basis of the variegated pathology and molecular biology of STS subgroups are ongoing as well, according to what is done in the medical treatment of advanced STS. Thus, decision making for adjuvant and neoadjuvant indications deserves personalization in clinical research and in clinical practice, taking profit from all multidisciplinary clinical skills available at a sarcoma reference center, though with a degree of subjectivity because of the limitations of available evidence.

  19. The mode of action of immunological adjuvants.

    Allison, A C

    1998-01-01

    Adjuvants augment immune responses to antigens and influence the balance between cell-mediated and humoral responses, as well as the isotypes of antibodies formed. New adjuvant formulations include antigen-carrying vehicles and small molecules with immunomodulating activity. Widely used two-phase vehicles comprise liposomes and microfluidized squalene or squalane emulsions. These are believed to target antigens to antigen-presenting cells, including dendritic cells (DC), follicular dendritic cells (FDC) and B-lymphocytes. Activation of complement generates C3d, which binds CR2 (CD21) on FDC and B-lymphocytes, thereby stimulating the proliferation of the latter and the generation of B-memory. Targeting of antigens to DC may favour cell-mediated immunity. Immunomodulating agents induce the production of cytokine cascades. In a primary cascade at injection sites TNF-alpha, GM-CSF and IL-1 are produced. TNF-alpha promotes migration of DC to lymphoid tissues, while GM-CSF and IL-1 accelerate the maturation of DC into efficient antigen-presenting cells for T-lymphocytes. In a secondary cytokine cascade in draining lymph nodes, DC produce IL-12, which induces Th1 responses with the production of IFN-gamma. The cytokines elicit cell-mediated immune responses and the formation of antibodies of protective isotypes, such as IgG2a in the mouse and IgG1 in humans. Antibodies of these isotypes activate complement and collaborate with antibody-dependent effector cells in protective immune responses. PMID:9554254

    2016-01-01

    Neoadjuvant chemotherapy is indicated in patients who can tolerate the side effects of a chemotherapy and with preoperative presentation of one of the following clinical risk situations: bulky disease with a maximal tumor diameter of > 4 cm, suspicious lymph nodes in magnetic resonance imaging (MRI), computed tomography (CT) scan or endosonography, histopathologically confirmed lymph node metastasis, or histopathologically documented risk factors such as G3 and L1V1. A neoadjuvant chemotherapy followed by surgery should be performed with cisplatin at a dosage of > 25 mg/m2 per week and an application interval of < 14 days. The previously published data suggests an improved rate of complete resection and reduced incidences of positive lymph nodes and parametric infiltration. Accordingly, the percentage of patients in need for adjuvant radiochemotherapy after operation can be significantly reduced. Some studies demonstrated a prolongation of progression-free and overall survival. Following the previously published studies, adjuvant chemotherapy after operation or after radiochemotherapy has no significant effect on the overall survival and, following the current guidelines, should be avoided.

    Full Text Available In the last half of the century, a large amount of substances has been used as immune adjuvant. The immune adjuvant effect of olive, soybean and corn oils in Swiss mice immunized with ovalbumin (OVA plus aluminum hydroxide or emulsified in Marcol, soybean, olive or corn oils was evaluated through the OVA-specific antibodies determined by ELISA and Passive Cutaneous Anaphylaxis. In this work the comparison of the intensity of the immune response was established by the Bayesian analysis. The adjuvant effect of the vegetable oils was shown to be more effective than aluminium hydroxide. Regarding to OVA-specific IgE synthesis, olive oil had the slowest adjuvant effect of the three vegetable oils. Accordingly, olive oil was the most convenient among the vegetable oils to be used as immune adjuvant, since it stimulated a higher production of OVA-specific Ig and lower levels of anti-OVA IgE.

    2001-01-01

    Perhaps no part of the health system is as imperiled by neoliberal economic reforms as the public drug sector. The national bill for pharmaceuticals can claim one-third of a developing country's annual health budget. This article describes the essential drugs program created by WHO in the 1980s to protect financially reduced ministries of health from the high prices charged by multinational pharmaceutical companies. It describes the backlash from the World Bank and UNICEF, which launched the Bamako Initiative and other community financing schemes and revolving drug plans in which individuals, families or community groups buy drugs above the wholesale purchase price; clinics use the proceeds to maintain drug supplies and subsidize other health services. When this plan failed, the Bank proposed outright privatization of drug purchase and supply, returning power to the multinational suppliers. The article ends with a consideration of patents and the new intellectual property rights as they pertain to pharmaceutical production in Africa. PMID:11469153

    Within less than a decade the World Bank has become the largest single source of finance (loans) for health in low and middle income countries as well as a major player in the field of pharmaceuticals. Often 20-50% of the recurrent government health budget in developing countries is used to procure drugs. Drugs are among the most salient and cost-effective elements of health care and often a key factor for the success of a health sector reform. However, pharmaceuticals are frequently being used irrationally, mainly due to market imperfections in health care, such as information asymmetries, leading to serious health problems and a heavy financial burden on the health system. Lending priorities set by the World Bank could be used to promote public health sector reform, leading to the rational use of affordable and available drugs of good quality in developing countries. This report provides the first analysis of World Bank activity in the pharmaceutical sector worldwide. The analysis of 77 staff appraisal reports, describing the planning phase of World Bank country projects, shows that 16% of the total World Bank health, nutrition and population budget, or approximately US$1.3 billion, has been committed to loans or credits supporting pharmaceutical activities in the programme countries between 1989-95. Roughly US$1.05 billion has been committed to procurement of drugs and medical equipment. Only 5% of the total pharmaceutical sector lending is committed to software components such as drug policy work and rational use of drugs. No more than 45% of the projects were developed in collaboration with pharmaceutical expertise. The World Bank is recommended to improve its pharmaceutical sector involvement by promoting drug policy research and development including national and international dialogue on pharmaceutical issues to ensure rational use of both drugs and loans. In this, the World Bank has an advantage given its experience from working with both the private and

  12. Quadrantectomy and adjuvant radiotherapy for breast cancer

    International Nuclear Information System (INIS)

    The conservative treatment of early breast cancer always requires irradiation of residual mammary tissue. The preliminary results obtained in 45 early breast cancer patients, who received quadrantectomy plus axillary dissection, followed by radiation of residual breast are reported. Radiation was performed by the two opposed field technique. In some cases the residual breast tissue was compressed using a special accessory provided with the Theratron 780. In addition to the tumor dose of 50 GY, 10 GY boots was added to the surgical scar using 7 MeV electrons. The 6 patients with positive axillary nodes received 6 courses of adjuvant chemotherapy (CMF) after radiotherapy. All patients are currently alive and free of disease. The 64% (29 patients) were followed up for at least 5 years, and 36% (16 patients) for at least 3 years. Only 2 cases of local recurrence were encountered (4,4%). The esthetic result was satisfactory in all cases. No side effects due to treatment were noted

    During the last decades, the focus of research in pharmaceutical technology has steadily shifted towards the development and optimisation of nano-scale drug delivery systems. As a result, electron microscopic methods are increasingly employed for the characterisation of pharmaceutical systems such as nanoparticles and microparticles, nanoemulsions, microemulsions, solid lipid nanoparticles, different types of vesicles, nanofibres and many more. Knowledge of the basic properties of these systems is essential for an adequate microscopic analysis. Classical transmission and scanning electron microscopic techniques frequently have to be adapted for an accurate analysis of formulation morphology, especially in case of hydrated colloidal systems. Specific techniques such as environmental scanning microscopy or cryo preparation are required for their investigation. Analytical electron microscopic techniques such as electron energy-loss spectroscopy or energy-dispersive X-ray spectroscopy are additional assets to determine the elemental composition of the systems, but are not yet standard tools in pharmaceutical research. This review provides an overview of pharmaceutical systems of interest in current research and strategies for their successful electron microscopic analysis. Advantages and limitations of the different methodological approaches are discussed and recent findings of interest are presented. PMID:22921788

    As a determining factor in various diseases and the leading known cause of preventable mortality and morbidity, tobacco use is the number one public health problem in developed countries. Facing this health problem requires authorities and health professionals to promote, via specific programs, health campaigns that improve patients' access to smoking cessation services. Pharmaceutical care has a number of specific characteristics that enable the pharmacist, as a health professional, to play an active role in dealing with smoking and deliver positive smoking cessation interventions. The objectives of the study were to assess the efficacy of a smoking cessation campaign carried out at a pharmaceutical care center and to evaluate the effects of pharmaceutical care on patients who decide to try to stop smoking. The methodology was an open, analytical, pre-post intervention, quasi-experimental clinical study performed with one patient cohort. The results of the study were that the promotional campaign for the smoking cessation program increased the number of patients from one to 22, and after 12 months into the study, 43.48% of the total number of patients achieved total smoking cessation. We can conclude that advertising of a smoking cessation program in a pharmacy increases the number of patients who use the pharmacy's smoking cessation services, and pharmaceutical care is an effective means of achieving smoking cessation.

    Anampa, Jesus; Makower, Della; Sparano, Joseph A

    2015-01-01

    Breast cancer is the most common cause of cancer and cancer death worldwide. Although most patients present with localized breast cancer and may be rendered disease-free with local therapy, distant recurrence is common and is the primary cause of death from the disease. Adjuvant systemic therapies are effective in reducing the risk of distant and local recurrence, including endocrine therapy, anti-HER2 therapy, and chemotherapy, even in patients at low risk of recurrence. The widespread use of adjuvant systemic therapy has contributed to reduced breast cancer mortality rates. Adjuvant cytotoxic chemotherapy regimens have evolved from single alkylating agents to polychemotherapy regimens incorporating anthracyclines and/or taxanes. This review summarizes key milestones in the evolution of adjuvant systemic therapy in general, and adjuvant chemotherapy in particular. Although adjuvant treatments are routinely guided by predictive factors for endocrine therapy (hormone receptor expression) and anti-HER2 therapy (HER2 overexpression), predicting benefit from chemotherapy has been more challenging. Randomized studies are now in progress utilizing multiparameter gene expression assays that may more accurately select patients most likely to benefit from adjuvant chemotherapy.

    2012-04-01

    The purpose of this study was to probe the fate of a model antigen, a cysteine-free mutant of bacteriophage T4 lysozyme, to the level of fine structural detail, as a consequence of its interaction with an aluminum (Al)-containing adjuvant. Fluorescence spectroscopy and differential scanning calorimetry were used to compare the thermal stability of the protein in solution versus adsorbed onto an Al-containing adjuvant. Differences in accessible hydrophobic surface areas were investigated using an extrinsic fluorescence probe, 8-Anilino-1-naphthalenesulfonic acid (ANS). As has been observed with other model antigens, the apparent thermal stability of the protein decreased following adsorption onto the adjuvant. ANS spectra suggested that adsorption onto the adjuvant caused an increase in exposure of hydrophobic regions of the protein. Electrostatic interactions drove the adsorption, and disruption of these interactions with high ionic strength buffers facilitated the collection of two-dimensional (15) N heteronuclear single quantum coherence nuclear magnetic resonance data of protein released from the adjuvant. Although the altered stability of the adsorbed protein suggested changes to the protein's structure, the fine structure of the desorbed protein was nearly identical to the protein's structure in the adjuvant-free formulation. Thus, the adjuvant-induced changes to the protein that were responsible for the reduced thermal stability were not observed upon desorption.

    2008-01-01

    BACKGROUND:Pancreatic cancer is an aggressive malignancy with a dismal prognosis. Radical surgery provides the only chance for a cure with a 5-year survival rate of 7%-25%. An effective adjuvant therapy is urgently needed to improve the surgical outcome. This review describes the current status of adjuvant therapy for pancreatic cancer, and highlights its controversies. DATA SOURCES:A Medline database search was performed to identify relevant articles using the keywords"pancreatic neoplasm", and"adjuvant therapy". Additional papers were identiifed by a manual search of the references from the key articles. RESULTS:Eight prospective randomized controlled trials (RCTs) on the use of adjuvant chemotherapy and chemoradiation for pancreatic cancer could be identiifed. The results for adjuvant regimens based on systemic 5-lfuorouracil with or without external radiotherapy were conlficting. The recent two RCTs on gemcitabine based regimen gave promising results. CONCLUSIONS:Based on the available data, no standard adjuvant therapy for pancreatic cancer can be established yet. The best adjuvant regimen remains to be determined in large-scale RCTs. Future trials should use a gemcitabine based regimen.

  3. Adjuvant radiation for vulvar carcinoma: improved local control

    International Nuclear Information System (INIS)

    Purpose: Local recurrence is a significant problem following primary surgery for advanced vulva carcinoma. The objectives of this study were to evaluate the impact of adjuvant vulvar radiation on local control in high risk patients and the impact of local recurrence on overall survival. Methods and Materials: From 1980-1994, 62 patients with invasive vulva carcinoma and either positive or close (less 8 mm) margins of excision were retrospectively studied. Thirty-one patients were treated with adjuvant radiation therapy to the vulva and 31 patients were observed after surgery. Kaplan-Meier estimates and the Cox proportional hazard regression model were used to evaluate the effect of adjuvant radiation therapy on local recurrence and overall survival. Independent prognostic factors for local recurrence and survival were also assessed. Results: Local recurrence occurred in 58% of observed patients and 16% in patients treated with adjuvant radiation therapy. Adjuvant radiation therapy significantly reduced local recurrence rates in both the close margin and positive margin groups (p = 0.036, p = 0.0048). On both univariate and multivariate analysis adjuvant radiation and margins of excision were significant prognostic predictors for local control. Significant determinants of actuarial survival included International Federation of Gynecologists and Obstetricians (FIGO) stage, percentage of pathologically positive inguinal nodes and margins of excision. The positive margin observed group had a significantly poorer actuarial 5 year survival than the other groups (p = 0.0016) and adjuvant radiation significantly improved survival for this group. The 2 year actuarial survival after developing local recurrence was 25%. Local recurrence was a significant predictor for death from vulva carcinoma (risk ratio 3.54). Conclusion: Local recurrence is a common occurrence in high risk patients. In this study adjuvant radiation therapy significantly reduced local recurrence rates and

    Full Text Available For the induction of robust humoral and cellular immune responses, a strong rationale exists to use vaccine-adjuvant combinations possessing both immune modulatory and enhanced delivery capabilities. Herein, we evaluated the combination of 2 different adjuvants, a TLR9 agonist, composed of synthetic oligodeoxynucleotides (ODN containing immunostimulatory CpG motifs (CpG, and ISCOMATRIX adjuvant (ISCOMATRIX, composed of saponin, phospholipid, and cholesterol, which possesses both immunostimulatory and delivery properties. While both individual adjuvants have been shown effective in numerous preclinical and clinical studies, it is likely that for optimal adjuvant activity a combined adjuvant approach will be necessary. Herein, using three different antigens, namely, hepatitis B surface antigen (HBsAg, ovalbumin (OVA, and influenza A haemagglutinin antigen (HA, we show in mice that some adjuvant effects of CpG and ISCOMATRIX are further enhanced if they are used in combination. In particular, with all three antigens, IFN-γ levels were greatly increased with the CpG/ISCOMATRIX combination. The ability of the CpG/ISCOMATRIX combination to induce antitumor responses when administered with OVA following administration to mice of a highly metastatic OVA-secreting tumor cell line (B16-OVA melanoma was also demonstrated. Thus the CpG/ISCOMATRIX combination may prove to be a valuable tool in the development of novel or improved vaccines.

    these CMF regimens has not been compared within the context of a randomised trial. Shifting from the 77B's classic CMF regimen to the 82B four-weekly IV regimen or the 89B three-weekly IV regimen was associated with a 30% increased risk of a DFS event in a multivariate analysis of a population-based cohort study. Furthermore, the four-weekly regimen used in 82B was associated with a 40% increase in mortality. The strengths of the design include identical selection criteria, uniform and prospective registration of treatment, tumour and patient characteristics. Caution is still required due to the non-experimental design of the comparison. Another finding was a substantial difference in the risk of amenorrhoea; and while 15% of patients aged 40 or younger in 77B had regular menses throughout chemotherapy, the corresponding percentage was 37 in 82B and 47 in 89B. The DBCG in collaboration with a Swedish and a Dutch centre participating in the DBCG trial 89B compared CMF with ovarian ablation in premenopausal high-risk breast cancer patients with ER-positive tumours. No significant differences were found in DFS or OS in the preplanned analysis, suggesting that the benefits of CMF may, at least in part, be explained by ovarian suppression in premenopausal patients with ER-positive tumours. However, these results are not clinically useful by themselves as other chemotherapy regimens have been more efficacious, and knowledge is still lacking regarding the benefits from adding ovarian suppression to chemotherapy plus tamoxifen. The results from the DBCG 77B and 82C are in accordance with other large adjuvant trials and the EBCTCG meta-analyses. The benefits obtained with any individual anticancer drug are largely determined by the cancer (somatic) genome; and by being a molecular target of anthracyclines, TOP2A aberrations could obviously be associated with cancer drug benefits. In the DBCG 89D, a significant heterogeneity was observed between a beneficial effect on DFS and OS

  7. The Vaccine Formulation Laboratory: a platform for access to adjuvants.

    2011-07-01

    Adjuvants are increasingly used by the vaccine research and development community, particularly for their ability to enhance immune responses and for their dose-sparing properties. However, they are not readily available to the majority of public sector vaccine research groups, and even those with access to suitable adjuvants may still fail in the development of their vaccines because of lack of knowledge on how to correctly formulate the adjuvants. This shortcoming led the World Health Organization to advocate for the establishment of the Vaccine Formulation Laboratory at the University of Lausanne, Switzerland. The primary mission of the laboratory is to transfer adjuvants and formulation technology free of intellectual property rights to academic institutions, small biotechnology companies and developing countries vaccine manufacturers. In this context, the transfer of an oil-in-water emulsion to Bio Farma, an Indonesian vaccine manufacturer, was initiated to increase domestic pandemic influenza vaccine production capacity as part of the national pandemic influenza preparedness plan.

  15. Learning impairment in honey bees caused by agricultural spray adjuvants.

    Directory of Open Access Journals (Sweden)

    Timothy J Ciarlo

    Full Text Available BACKGROUND: Spray adjuvants are often applied to crops in conjunction with agricultural pesticides in order to boost the efficacy of the active ingredient(s. The adjuvants themselves are largely assumed to be biologically inert and are therefore subject to minimal scrutiny and toxicological testing by regulatory agencies. Honey bees are exposed to a wide array of pesticides as they conduct normal foraging operations, meaning that they are likely exposed to spray adjuvants as well. It was previously unknown whether these agrochemicals have any deleterious effects on honey bee behavior. METHODOLOGY/PRINCIPAL FINDINGS: An improved, automated version of the proboscis extension reflex (PER assay with a high degree of trial-to-trial reproducibility was used to measure the olfactory learning ability of honey bees treated orally with sublethal doses of the most widely used spray adjuvants on almonds in the Central Valley of California. Three different adjuvant classes (nonionic surfactants, crop oil concentrates, and organosilicone surfactants were investigated in this study. Learning was impaired after ingestion of 20 µg organosilicone surfactant, indicating harmful effects on honey bees caused by agrochemicals previously believed to be innocuous. Organosilicones were more active than the nonionic adjuvants, while the crop oil concentrates were inactive. Ingestion was required for the tested adjuvant to have an effect on learning, as exposure via antennal contact only induced no level of impairment. CONCLUSIONS/SIGNIFICANCE: A decrease in percent conditioned response after ingestion of organosilicone surfactants has been demonstrated here for the first time. Olfactory learning is important for foraging honey bees because it allows them to exploit the most productive floral resources in an area at any given time. Impairment of this learning ability may have serious implications for foraging efficiency at the colony level, as well as potentially many

    Following a long series of injections of homologous immunoglobulin in complete and incomplete Freund's adjuvant into mink, a moderate elevation in the level of gammaglobulin in the serum was observed in a few animals. Relatively mild pathological changes also were seen in liver, spleen, lymph nodes, lungs and kidney. It is concluded that the injection of Freund's adjuvant, under the experimental conditions described, produced lesions which were readily distinguishable from the lesions characteristic of aleutian disease of mink.

  17. Pharmaceutical cocrystals: walking the talk.

    Science.gov (United States)

    Bolla, Geetha; Nangia, Ashwini

    2016-06-28

    Pharmaceutical cocrystals belong to a sub-class of cocrystals wherein one of the components is a drug molecule (or an active pharmaceutical ingredient, API) and the second is a benign food or drug grade additive (generally regarded as safe, GRAS). The two components are hydrogen-bonded in a fixed stoichiometric ratio in the crystal lattice. In the past decade, pharmaceutical cocrystals have demonstrated significant promise in their ability to modify the physicochemical and pharmacokinetic properties of drug substances, such as the solubility and dissolution rate, bioavailability, particle morphology and size, tableting and compaction, melting point, physical form, biochemical and hydration stability, and permeability. In this feature review, we highlight some prominent examples of drug cocrystals which exhibit variable hardness/softness and elasticity/plasticity depending on coformer selection, improvement of solubility and permeability in the same cocrystal, increase of the melting point for solid formulation, enhanced color performance, photostability and hydration stability, and a longer half-life. Cocrystals of flavanoids and polyphenols can make improved pharmaceuticals and also extend to the larger class of nutraceuticals. The application of crystal engineering to assemble ternary cocrystals expands this field to drug-drug cocrystals which may be useful in multi-drug resistance, mitigating side effects of drugs, or attenuating/enhancing drug action synergistically by rational selection. The advent of new techniques for structural characterization beyond the standard X-ray diffraction will provide a better understanding of drug phases which are at the borderline of crystalline-amorphous nature and even newer opportunities in the future.

    Pharmaceutical trafficking is common issue in countries where they are under stricter dispensing regime with monitoring of users. Most commonly smuggled pharmaceuticals include trade names Paralen Plus, Modafen, Clarinase repetabs, Aspirin complex, etc. These are transported mainly from Eastern Europe (e.g. Poland, Ukraine, Russia) to countries like Czech Republic, which is said to have one of the highest number of methamphetamine producers in Europe. The aim of this paper is to describe the possibility of terahertz spectroscopy utilization as an examining tool to distinguish between pharmaceuticals containing pseudoephedrine compounds and those without it. Selected medicaments for experimental part contain as an active ingredient pseudoephedrine hydrochloride or pseudoephedrine sulphate. Results show a possibility to find a pseudoephedrine compound spectra in samples according to previously computed and experimentally found ones, and point out that spectra of same brand names pills may vary according to their expiration date, batch, and amount of absorbed water vapours from ambience. Mislead spectrum also occurs during experimental work in a sample without chosen active ingredient, which shows persistent minor inconveniences of terahertz spectroscopy. All measurement were done on the TPS Spectra 3000 instrument.

The dramatic increase in accessibility and availability of information empowered the consumer by closing the information gap between the consumer and different suppliers. The objective of this article is to review many new internet-supported applications related to the pharmaceutical market. E-commerce is divided into two major components: Business to Consumer (B to C), and Business to Business (B to B). The main applications in B to C are dissemination of medical and drug information, and the sale of drugs through the Internet. Medical information on the Internet is vast and very helpful for patients, however, its reliability is not guaranteed. Online pharmacies increase the accessibility and availability of drugs. Nevertheless, several obstacles such as security of the data provided (both financial and clinical) prevent the widespread use of online pharmacies. Another risk is the health authorities' inability to regulate Internet sites effectively. Therefore, unregulated sale of prescription drugs, fake or substandard, often occurs on the Internet. B to B relates to physicians, clinics, hospitals, HMO's and pharmaceutical companies. There is a vast number of applications ranging from clinical research, marketing and sales promotion, to drug distribution and logistics. In conclusion, the Internet is dynamic and has contributed to the development of numerous new applications in the field of pharmaceuticals. Regulatory authorities should be active in developing new policies that will deal with those new Internet-based applications. PMID:12803063

  2. Squalene and squalane emulsions as adjuvants.

    Science.gov (United States)

    Allison, A C

    1999-09-01

    Microfluidized squalene or squalane emulsions are efficient adjuvants, eliciting both humoral and cellular immune responses. Microfluidization stabilizes the emulsions and allows sterilization by terminal filtration. The emulsions are stable for years at ambient temperature and can be frozen. Antigens are added after emulsification so that conformational epitopes are not lost by denaturation and to facilitate manufacture. A Pluronic block copolymer can be added to the squalane or squalene emulsion. Soluble antigens administered in such emulsions generate cytotoxic T lymphocytes able to lyse target cells expressing the antigen in a genetically restricted fashion. Optionally a relatively nontoxic analog of muramyl dipeptide (MDP) or another immunomodulator can be added; however, the dose of MDP must be restricted to avoid systemic side effects in humans. Squalene or squalane emulsions without copolymers or MDP have very little toxicity and elicit potent antibody responses to several antigens in nonhuman primates. They could be used to improve a wide range of vaccines. Squalene or squalane emulsions have been administered in human cancer vaccines, with mild side effects and evidence of efficacy, in terms of both immune responses and antitumor activity.

    2016-01-01

    Pharmaceuticals and their active metabolites are one of the significantly emerging environmental toxicants. The major routes of entry of pharmaceuticals into the environment are industries, hospitals, or direct disposal of unwanted or expired drugs made by the patient. The most important and distinct features of pharmaceuticals are that they are deliberately designed to have an explicit mode of action and designed to exert an effect on humans and other living systems. This distinctive feature makes pharmaceuticals and their metabolites different from other chemicals, and this necessitates the evaluation of the direct effects of pharmaceuticals in various environmental compartments as well as to living systems. In this background, the alarming situation of ecotoxicity of diverse pharmaceuticals have forced government and nongovernment regulatory authorities to recommend the application of in silico methods to provide quick information about the risk assessment and fate properties of pharmaceuticals as well as their ecological and indirect human health effects. This chapter aims to offer information regarding occurrence of pharmaceuticals in the environment, their persistence, environmental fate, and toxicity as well as application of in silico methods to provide information about the basic risk management and fate prediction of pharmaceuticals in the environment. Brief ideas about toxicity endpoints, available ecotoxicity databases, and expert systems employed for rapid toxicity predictions of ecotoxicity of pharmaceuticals are also discussed.

    Today, the goals of pharmaceutical policy and medical practice are often undermined due to institutional corruption - that is, widespread or systemic practices, usually legal, that undermine an institution's objectives or integrity. In this symposium, 16 articles investigate the corruption of pharmaceutical policy, each taking a different look at the sources of corruption, how it occurs, and what is corrupted. We will see that the pharmaceutical industry's own purposes are often undermined. Furthermore, pharmaceutical industry funding of election campaigns and lobbying skews the legislative process that sets pharmaceutical policy. Moreover, certain practices have corrupted medical research, the production of medical knowledge, the practice of medicine, drug safety, the Food and Drug Administration's oversight of the pharmaceutical market, and the trustworthiness of patient advocacy organizations.

    Pharmaceutical discovery and development is expensive and highly risky, even for multinational corporations. As a developing country with limited financial resources, China has been seeking the most cost-effective means to reach the same level of innovation and productivity as Western countries in the pharmaceutical industry sector. After more than 50 years of building up talent and experience, the time for China to become a powerhouse in pharmaceutical innovation is finally approaching. Returnee scientists to China are one of the reasons for the wave of new discovery and commercialization occurring within the country. The consolidation of local Chinese pharmaceutical companies and foreign investment is also providing an agreeable environment for the evolution of a new generation of biotechnology. The opportunity for pharmaceutical innovation is also being expedited by the entry of multinational companies into the Chinese pharmaceutical market, and by the outsourcing of research from these companies to China.

    Mohan, Teena; Verma, Priyanka; Rao, D Nageswara

    2013-11-01

    The pure recombinant and synthetic antigens used in modern day vaccines are generally less immunogenic than older style live/attenuated and killed whole organism vaccines. One can improve the quality of vaccine production by incorporating immunomodulators or adjuvants with modified delivery vehicles viz. liposomes, immune stimulating complexes (ISCOMs), micro/nanospheres apart from alum, being used as gold standard. Adjuvants are used to augment the effect of a vaccine by stimulating the immune system to respond to the vaccine, more vigorously, and thus providing increased immunity to a particular disease. Adjuvants accomplish this task by mimicking specific sets of evolutionary conserved molecules which include lipopolysaccharides (LPS), components of bacterial cell wall, endocytosed nucleic acids such as dsRNA, ssDNA and unmethylated CpG dinucleotide containing DNA. This review provides information on various vaccine adjuvants and delivery vehicles being developed to date. From literature, it seems that the humoral immune responses have been observed for most adjuvants and delivery platforms while viral-vector, ISCOMs and Montanides have shown cytotoxic T-cell response in the clinical trials. MF59 and MPL® have elicited Th1 responses, and virus-like particles (VLPs), non-degradable nanoparticle and liposomes have also generated cellular immunity. Such vaccine components have also been evaluated for alternative routes of administration with clinical success reported for intranasal delivery of viral-vectors and proteosomes and oral delivery of VLP vaccines.

    Full Text Available In the last decades, significant progress in research and clinics has been made to offer possible innovative therapeutics for the management of allergic diseases. However, current allergen immunotherapy shows limitations concerning the long-term efficacy and safety due to local side effects and risk of anaphylaxis. Thus, effective and safe vaccines with reduced dose of allergen have been developed using adjuvants. Nevertheless, the use of adjuvants still has several disadvantages, which limits its use in human vaccines. In this context, several novel adjuvants for allergen immunotherapy are currently being investigated and developed. Currently, nanoparticles-based allergen-delivery systems have received much interest as potential adjuvants for allergen immunotherapy. It has been demonstrated that the incorporation of allergens into a delivery system plays an important role in the efficacy of allergy vaccines. Several nanoparticles-based delivery systems have been described, including biodegradable and nondegradable polymeric carriers. Therefore, this paper provides an overview of the current adjuvants used for allergen immunotherapy. Furthermore, nanoparticles-based allergen-delivery systems are focused as a novel and promising strategy for allergy vaccines.

Adjuvants accomplish this task by mimicking specific sets of evolutionary conserved molecules which include lipopolysaccharides (LPS), components of bacterial cell wall, endocytosed nucleic acids such as dsRNA, ssDNA and unmethylated CpG dinucleotide containing DNA. This review provides information on various vaccine adjuvants and delivery vehicles being developed to date. From literature, it seems that the humoral immune responses have been observed for most adjuvants and delivery platforms while viral-vector, ISCOMs and Montanides have shown cytotoxic T-cell response in the clinical trials. MF59 and MPL® have elicited Th1 responses, and virus-like particles (VLPs), non-degradable nanoparticle and liposomes have also generated cellular immunity. Such vaccine components have also been evaluated for alternative routes of administration with clinical success reported for intranasal delivery of viral-vectors and proteosomes and oral delivery of VLP vaccines.

    In the last decades, significant progress in research and clinics has been made to offer possible innovative therapeutics for the management of allergic diseases. However, current allergen immunotherapy shows limitations concerning the long-term efficacy and safety due to local side effects and risk of anaphylaxis. Thus, effective and safe vaccines with reduced dose of allergen have been developed using adjuvants. Nevertheless, the use of adjuvants still has several disadvantages, which limits its use in human vaccines. In this context, several novel adjuvants for allergen immunotherapy are currently being investigated and developed. Currently, nanoparticles-based allergen-delivery systems have received much interest as potential adjuvants for allergen immunotherapy. It has been demonstrated that the incorporation of allergens into a delivery system plays an important role in the efficacy of allergy vaccines. Several nanoparticles-based delivery systems have been described, including biodegradable and nondegradable polymeric carriers. Therefore, this paper provides an overview of the current adjuvants used for allergen immunotherapy. Furthermore, nanoparticles-based allergen-delivery systems are focused as a novel and promising strategy for allergy vaccines.

    Metastatic melanoma has a poor prognosis; the median survival for patients with stage IV melanoma ranges from 8 to 18 months after diagnosis. Interferon-α provides significant improvement in disease-free survival at the cost of poor tolerability. Identifying patients who benefit the most may improve the cost:benefit ratio. In addition, no data exist for the role of adjuvant therapy in noncutaneous melanoma. Molecular profiles may help to identify patients who benefit the most from adjuvant interferon therapy. In this review, the American Joint Commission on Cancer 2009 staging criteria and emerging biomarker data to guide adjuvant treatment decisions will be discussed. Several criteria to guide selection of patients are discussed in detail. These include Breslow thickness, number of positive lymph nodes, whether or not the primary lesion has ulcerated, immunologic markers, and cytokine profiles. Substantial progress has been made in deciding which patients benefit from interferon-α adjuvant therapy. Interferon-α is the only agent currently approved for the adjuvant treatment of this deadly disease, despite its side effect profile. More effective drugs with better tolerability are needed.

    Chiral therapeutics already makes up over one-third of pharmaceutical drugs currently sold worldwide. This is a growing industry with global chiral drug sales for 2002 increasing by 12%to $160 billion (Technology Catalysts International) of a total drug market of $410bn. The increasing demand to produce enantiomerically pure pharmaceuticals, agrochemicals, flavors, and other fine chemicals has advanced the field of asymmetric catalytic technologies.We aim to become a high value technology provider and partner in the chiral therapeutics industry by offering proprietary catalysts, novel building blocks, and collaborative synthetic solutions. In decade, we have developed a set of novel chiral homogeneous phosphorus ligands such as Binaphane, Me-KetalPhos, TangPhos, f-Binaphane, Me-f-KetalPhos, C4TunePhos and Binapine,which we called Chiral Ligand ToolKit. Complementing the ToolKit, (R, S, S, R)-DIOP*, T-Phos,o-BIPHEP, o-BINAPO and FAP were added recently[1].These ligands can be applied to a broad variety of drug structural features by asymmetric hydrogenation of dehydroamino acid derivatives, enamides, unsatisfied acids and esters, ketones,beta ketoesters, imines and cyclic imines. And ligand FAP had been apllied succefully in allylic alkylation and [3+2] cycloaddition.

    The present effort is an attempt to reduce pollution caused by the discharge of untreated wastewater (effluents) to the environment by using a low cost method. The effluent was bio-remediated using yeast and amylase as the active agents. The greater the decomposable matters present in an effluent, the greater the oxygen demand; the greater the Biological Oxygen Demand (BOD) and Chemical Oxygen Demand(COD) values, the less Dissolved Oxygen(DO) values. 10g of yeast and amylase were added to 1000ml each of pharmaceutical effluent. 150 ml of the effluent (from the yeast and amylase) dosed was withdrawn weekly for analysis alongside with the effluent without enzymes for turbidity, DO, BOD and COD. After a period of six weeks the effluent dosed with yeast gave the highest performance followed by that dosed with amylase. The result shows that as time increases, the amount of oxygen demand reduces while the dissolved oxygen content of the effluent increases. This indicates that the yeast enzyme was able to aid remediation of the pharmaceutical effluent.

    Development of effective vaccine mediated immune responses relies on the use of vaccine adjuvants capable of enhancing and directing the adaptive immune response to the antigen. When used as vaccine adjuvants, type I interferon inducing agents can elicit potent effector/memory T cell responses and humoral immunity. Distinct sequences of single stranded synthetic oligodeoxynucleotides containing unmethylated cytosine-phosphate-guanine oligodeoxynucleotide motifs (CpG ODN) can generate type I interferon production via a TLR9-MyD88-IRF7-mediated signaling pathway. Here, we describe two different methods of preparing CpG ODN-based vaccine adjuvant formulations that can induce a robust IFNα response from human peripheral blood mononuclear cells. PMID:27076306

    The safety and immunogenicity profiles of currently available recombinant hepatitis B vaccines are excellent. However, it remains a real challenge to induce protective immunity in the target groups that respond poorly or not at all to conventional vaccines. Ideally, a hepatitis B vaccine can be developed that conveys lifelong protection against infection rapidly after the injection of a single dose. Although this goal is far from being reached, important improvements have been made. Novel vaccine adjuvants have been developed that enhance the immunogenicity of recombinant hepatitis B vaccines while maintaining a good safety profile. The different adjuvants and adjuvant systems that are discussed herein have all been thoroughly evaluated in clinical trials and some have reached or are close to reach the market. PMID:25523196

  7. Does Adjuvant Radiotherapy Suppress Liver Regeneration After Partial Hepatectomy?

    International Nuclear Information System (INIS)

    Purpose: To analyze the influence of the adjuvant radiotherapy (RT) on the liver regeneration and liver function after partial hepatectomy (PH). Methods and Materials: Thirty-four patients who underwent PH for biliary tract cancer between October 2003 and July 2005 were reviewed. Hemihepatectomy was performed in 14 patients and less extensive surgery in 20. Of the patients, 19 patients had no adjuvant therapy (non-RT group) and 15 underwent adjuvant RT by a three-dimensional conformal technique (RT group). Radiation dose range was 40 to 50 Gy (median, 40 Gy). Liver volume on computed tomography and the results of liver function tests at 1, 4, 12, 24, and 52 weeks after PH were compared between the RT and non-RT groups. Results: The preoperative characteristics were identical for both groups. During the interval between Weeks 4 and 12 when adjuvant RT was delivered in the RT group, the increase in liver volume was significantly smaller in the RT group than non-RT group (22.9 ± 38.3cm3 and 81.5 ± 75.6cm3, respectively, p = 0.007). However, the final liver volume measured at 1 year after PH did not differ between the two groups (p = 0.878). Liver function tests were comparable for both groups. The resection extent and original liver volume was independent factors for final liver volume measured at 1 year after PH. Conclusions: In this study, adjuvant RT delayed the liver regeneration process after PH, but the volume difference between the two study groups became nonsignificant after 1 year. Adjuvant RT had no additional adverse effect on liver function after PH.

    Full Text Available There is no universally accepted standard approach to treat patients with pancreatic cancer in the adjuvant setting. This controversy derives from several studies, each fraught with its own limitations. Standards of care also vary depending on which side of the Atlantic you are on: chemo-radiotherapy followed by chemotherapy is considered the optimal therapy in North America (GITSG, RTOG while chemotherapy alone is the current standard in Europe (ESPAC-1, CONKO. Whether gemcitabine is superior to 5-FU remains to be learnt from the ESPAC-3 study currently on-going in Europe. A number of important questions have yet to be fully addressed: • What is the absolute value of radiotherapy in this setting? • How should radiotherapy be delivered, if at all? • What should be the time to deliver of either or both therapeutic modalities in the adjuvant setting? • Are there any patients who can benefit from the combined modality? • What is the most appropriate chemotherapeutic agent(s to administer in the adjuvant setting? • Is there any role of integrating the novel/targeted agents, albeit the negative studies in the metastatic setting? • What are the new developments (such as vaccines, pancreas cancer stem cells, etc. in this area?

  4. Oily adjuvants and autoimmunity: now time for reconsideration?

    Science.gov (United States)

    Whitehouse, M

    2012-02-01

    Immunologists have relied heavily on oil-based adjuvants to generate antibodies or induce auto-allergic responses in experimental animals. These are rarely used today for human vaccination because of their persistent irritancies and propensity to cause ulcers at sites of injection. However oily materials with adjuvant properties abound in our modern environment, both personal and extraneous. Their inadvertent impact as cryptotoxins may contribute to the rising incidence of auto-allergic diseases in recent times. Experimentally, the potential adjuvanticity of various oils, fats and other lipids can be evaluated by their ability (or otherwise) to induce auto-allergic disease(s) in rats and mice with, or even without, the addition of a mycobacterial immunostimulant. Genetic factors have been recognized that determine an animal's susceptibility or resistance to these oil-induced immunopathies. So it may be profitable to further characterize these factors, first in animals and then perhaps in human populations, to help find ways to enhance natural resistance to those adjuvant-active oils that may be widely distributed in the personal environment, notably mineral oil(s). (The six tables in this article summarize some relevant facts and a few conjectures.) A caveat: This review is restricted to the adjuvant properties of some oils in the personal environment. It does not cover the mechanisms of adjuvanticity.

    Full Text Available Hydrochlorothiazide is a diuretic used to treat hypertension that belongs to class IV of the Biopharmaceutics Classification System. The drug was evaluated by quality control, thermal characterization tests, and pharmaceutical formulation compatibility studies. It was concluded that the generic drug, Lab 2, was not a pharmaceutical equivalent. The compounded drugs, Lab 5 and Lab 6, produced unsatisfactory but expected results, since there is no requirement for dissolution and dissolution profile testing for the commercialization of these products. In a compatibility study, lactose and mannitol were shown to be incompatible with HCTZ, which may explain the lack of equivalence of the generic pharmaceutical product, associated with other situations.

    2011-01-01

    Currently used pharmaceutical nanocarriers, such as liposomes, micelles, and polymeric nanoparticles, demonstrate a broad variety of useful properties, such as longevity in the body; specific targeting to certain disease sites; enhanced intracellular penetration; contrast properties allowing for direct carrier visualization in vivo; stimili-sensitivity, and others. Some of those pharmaceutical carriers have already made their way into clinic, while others are still under preclinical development. In certain cases, the pharmaceutical nanocarriers combine several of the listed properties. Long-circulating immunoliposomes capable of prolonged residence in the blood and specific target recognition represent one of examples of this kind. The engineering of multifunctional pharmaceutical nanocarriers combining several useful properties in one particle can significantly enhance the efficacy of many therapeutic and diagnostic protocols. This paper considers the current status and possible future directions in the emerging area of multifunctional nanocarriers with primary attention on the combination of such properties as longevity, targetability, intracellular penetration, contrast loading, and stimuli sensitivity.

    Surveillance of physicians' prescribing patterns and the accumulation and sale of these data for pharmaceutical marketing are currently the subjects of legislation in several states and action by state and national medical associations. Contrary to common perception, the growth of the health care information organization industry has not been limited to the past decade but has been building slowly over the past 50 years, beginning in the 1940s when growth in the prescription drug market fueled industry interest in understanding and influencing prescribing patterns. The development of this surveillance system was not simply imposed on the medical profession by the pharmaceutical industry but was developed through the interactions of pharmaceutical salesmen, pharmaceutical marketers, academic researchers, individual physicians, and physician organizations. Examination of the role of physicians and physician organizations in the development of prescriber profiling is directly relevant to the contemporary policy debate surrounding this issue.

    Managing the supply chain plays an important role in creating competitive advantages for companies. Adequate information flow in supply chain is one of the most important issues in SCM. Therefore, using certain Information Systems can have a significant role in managing and integrating data and information within the supply chain. Pharmaceutical supply chain is more complex than many other supply chains, in the sense that it can affect social and political perspectives. On the other hand, managing the pharmaceutical supply chain is difficult because of its complexity and also government regulations in this field. Although, Iran has progressed a lot in pharmaceutical manufacturing, still there are many unsolved issues in managing the information flow in the pharmaceutical supply chain. In this study, we reviewed the benefits of using different levels of an integrated information system in the supply chain and the possible challenges ahead. PMID:26664401

    Puthli, Shivanand P

    2010-01-01

    Growing research expenditure, regulatory framework and generic erosion have forced pharmaceutical companies globally to resort to pharmaceutical technology management (PTM). Indeed, the pharmaceutical industry has witnessed the impact of innovative drug delivery and device technologies and their influence on business. PTM has given a new business insight with greater profits and enhancement of product franchise. Promising breakthrough technologies have not been able to reach a commercial platform largely owing to lack of capital at the preliminary stages of the product development program. Intellectual property plays a considerable role in protecting innovative technologies. Joint ventures and strategic alliances also become important for commercializing a new technology. The synergy of PTM with options of in-licensing is expected to infuse newer opportunities to the pharmaceutical business. PMID:20017657

    As an emerging technology, THz spectroscopy has gained increasing attention in the pharmaceutical area during the last decade. This attention is due to the fact that (1) it provides a promising alternative approach for in-depth understanding of both intermolecular interaction among pharmaceutical molecules and pharmaceutical product quality attributes; (2) it provides a promising alternative approach for enhanced process understanding of certain pharmaceutical manufacturing processes; and (3) the FDA pharmaceutical quality initiatives, most noticeably, the Process Analytical Technology (PAT) initiative. In this work, the current status and progress made so far on using THz spectroscopy for pharmaceutical development and pharmaceutical PAT applications are reviewed. In the spirit of demonstrating the utility of first principles modeling approach for addressing model validation challenge and reducing unnecessary model validation "burden" for facilitating THz pharmaceutical PAT applications, two scientific case studies based on published THz spectroscopy measurement results are created and discussed. Furthermore, other technical challenges and opportunities associated with adapting THz spectroscopy as a pharmaceutical PAT tool are highlighted.

    2011-11-01

    The bromination of five selected pharmaceuticals (metoprolol, naproxen, amoxicillin, phenacetin, and hydrochlorothiazide) was studied with these compounds individually dissolved in ultra-pure water. The apparent rate constants for the bromination reaction were determined as a function of the pH, obtaining the sequence amoxicillin>naproxen>hydrochlorothiazide≈phenacetin≈metoprolol. A kinetic mechanism specifying the dissociation reactions and the species formed for each compound according to its pK(a) value and the pH allowed the intrinsic rate constants to be determined for each elementary reaction. There was fairly good agreement between the experimental and calculated values of the apparent rate constants, confirming the goodness of the proposed reaction mechanism. In a second stage, the bromination of the selected pharmaceuticals simultaneously dissolved in three water matrices (a groundwater, a surface water from a public reservoir, and a secondary effluent from a WWTP) was investigated. The pharmaceutical elimination trend agreed with the previously determined rate constants. The influence of the main operating conditions (pH, initial bromine dose, and characteristics of the water matrix) on the degradation of the pharmaceuticals was established. An elimination concentration profile for each pharmaceutical in the water matrices was proposed based on the use of the previously evaluated apparent rate constants, and the theoretical results agreed satisfactorily with experiment. Finally, chlorination experiments performed in the presence of bromide showed that low bromide concentrations slightly accelerate the oxidation of the selected pharmaceuticals during chlorine disinfection.

    2012-08-15

    Rejection of four pharmaceutical compounds, carbamazepine, diclofenac, ibuprofen and naproxen, by forward osmosis (FO) membranes was investigated in this study. For the first time, the rejection efficiency of the pharmaceutical compounds was compared between commercial cellulose triacetate (CTA) based membranes and thin film composite (TFC) polyamide based membranes. The rejection behavior was related to membrane interfacial properties, physicochemical characteristics of the pharmaceutical molecules and feed solution pH. TFC polyamide membranes exhibited excellent overall performance, with high water flux, excellent pH stability and great rejection of all pharmaceuticals investigated (>94%). For commercial CTA based FO membranes, hydrophobic interaction between the compounds and membranes exhibited strong influence on their rejection under acidic conditions. The pharmaceuticals rejection was well correlated to their hydrophobicity (log D). Under alkaline conditions, both electrostatic repulsion and size exclusion contributed to the removal of deprotonated molecules. The pharmaceuticals rejection by CTA-HW membrane at pH 8 followed the order: diclofenac (99%)>carbamazepine (95%)>ibuprofen (93%) ≈ naproxen (93%). These results can be important for FO membrane synthesis, modification and their application in water purification. PMID:22640821

    Synthetic oligodeoxynucleotides (ODNs) containing unmethylated CpG motifs trigger cells that express Toll-like receptor 9 (including human plasmacytoid dendritic cells and B cells) to mount an innate immune response characterized by the production of Th1 and proinflammatory cytokines. When used as vaccine adjuvants, CpG ODNs improve the function of professional antigen-presenting cells and boost the generation of humoral and cellular vaccine-specific immune responses. These effects are optimized by maintaining ODNs and vaccine in close proximity. The adjuvant properties of CpG ODNs are observed when administered either systemically or mucosally, and persist in immunocompromised hosts. Preclinical studies indicate that CpG ODNs improve the activity of vaccines targeting infectious diseases and cancer. Clinical trials demonstrate that CpG ODNs have a good safety profile and increase the immunogenicity of coadministered vaccines. PMID:21506647

    Full Text Available Vaccines are considered one of the greatest medical achievements in the battle against infectious diseases. However, the intractability of various diseases such as hepatitis C, HIV/AIDS, malaria, tuberculosis, and cancer poses persistent hurdles given that traditional vaccine-development methods have proven to be ineffective; as such, these challenges have driven the emergence of novel vaccine design approaches. In this regard, much effort has been put into the development of new safe adjuvants and vaccine platforms. Of particular interest, the utilization of plant virus-like nanoparticles and recombinant plant viruses has gained increasing significance as an effective tool in the development of novel vaccines against infectious diseases and cancer. The present review summarizes recent advances in the use of plant viruses as nanoparticle-based vaccines and adjuvants and their mechanism of action. Harnessing plant-virus immunogenic properties will enable the design of novel, safe, and efficacious prophylactic and therapeutic vaccines against disease.

However, DC-based vaccines have only exhibited minimal effectiveness against established tumours in mice and humans. The use of appropriate adjuvant enhances the efficacy of DC based cancer vaccines in treating tumours. Methods In this study we have used tocotrienol-rich fraction (TRF, a non-toxic natural compound, as an adjuvant to enhance the effectiveness of DC vaccines in treating mouse mammary cancers. In the mouse model, six-week-old female BALB/c mice were injected subcutaneously with DC and supplemented with oral TRF daily (DC+TRF and DC pulsed with tumour lysate from 4T1 cells (DC+TL. Experimental mice were also injected with DC pulsed with tumour lysate and supplemented daily with oral TRF (DC+TL+TRF while two groups of animal which were supplemented daily with carrier oil (control and with TRF (TRF. After three times vaccination, mice were inoculated with 4T1 cells in the mammary breast pad to induce tumour. Results Our study showed that TRF in combination with DC pulsed with tumour lysate (DC+TL+TRF injected subcutaneously significantly inhibited the growth of 4T1 mammary tumour cells as compared to control group. Analysis of cytokines production from murine splenocytes showed significant increased productions of IFN-γ and IL-12 in experimental mice (DC+TL+TRF compared to control, mice injected with DC without TRF, mice injected with DC pulsed with tumour lysate and mice supplemented with TRF alone. Higher numbers of cytotoxic T cells (CD8 and natural killer cells (NK were observed in the peripheral blood of TRF adjuvanted DC pulsed tumour lysate mice. Conclusion Our study show that TRF has the potential to be an adjuvant to augment DC based immunotherapy.

    Since the discovery of the human T cell-defined tumor antigen, the cancer immunotherapy field has rapidly progressed, with the research and development of cancer immunotherapy, including cancer vaccines, being conducted actively. However, the disadvantages of most cancer vaccines include relatively weak immunogenicity and immune escape or exhaustion. Adjuvants with innate immunostimulatory activities have been used to overcome these issues, and these agents have been shown to enhance the immunogenicity of cancer vaccines and to act as mono-therapeutic anti-tumor agents. CpG ODN, an agonist for TLR9, is one of the promising nucleic acid-based adjuvants, and it is a potent inducer of innate immune effector functions. CpG ODN suppresses tumor growth in the absence of tumor antigens and peptide administration. Therefore, CpG ODN is expected to be useful as a cancer vaccine adjuvant as well as a cancer immunotherapy agent. In this review, we discuss the potential therapeutic applications and mechanisms of CpG ODN for cancer immunotherapy. PMID:26469159

    Alzheimer's Disease (AD) is a slowly progressing neurodegenerative disorder representing a major health concern worldwide. This disorder is characterised by progressive dementia and cognitive decline. The pathological hallmarks of AD include the presence of Aβ plaques and tau neurofibrils. Research has shown that oxidative stress represents a major risk factor associated with AD pathology. Accumulation of Aβ plaques and relative lack of antioxidant defence mechanisms, including cellular antioxidant enzymes and dietary antioxidants like vitamins, assist in the exacerbation of oxidative stress. Reactive Oxygen Species (ROS) produced as the result of oxidative stress, that increase structural and functional abnormalities in brain neurons, which then manifests as dementia and decline in cognition. Data from numerous epidemiological studies suggests that nutrition is one of the most important yet modifiable risk factors for AD. Since oxidative stress contributes a great deal in the development and progression of AD, anything that could attenuate oxidative stress would help in decreasing the prevalence and incidence of AD. There is increasing evidence that supports the use of different antioxidant as an adjuvant treatment for AD. Vitamins are one such antioxidant that can be used as an adjuvant in AD treatment. This paper will focus on the evidence, based on current literature, linking the use of vitamin supplementations as an adjuvant treatment for AD. PMID:27656493

    A novel therapeutic strategy is required for autoimmune diseases characterized by the production of autoantibody, because current clinical strategies have limitations. Vaccination against autoimmune diseases is a feasible strategy because vaccines induce immune response memory and the antigen specificity. However, no suitable adjuvant is available to direct the immune response toward tolerance or suppression. In the current study, we evaluated whether kynurenine (Kyn) could serve as a novel suppressive adjuvant to decrease the humoral immune responses against hepatitis A virus (HAV) in the ICR mouse model in vivo and lipopolysaccharide (LPS) in B cells in vitro. The underlying mechanisms of Kyn-mediated suppression of LPS-induced IgM responses were explored. The results showed that Kyn significantly decreased HAV immunogenicity when co-administered with HAV, and that Kyn (100 μM/1000 μM) impaired IgM generation compared with that induced by LPS alone. We also demonstrated that microRNA30b (miR30b) played a critical role in the process of Kyn-mediated suppression of IgM responses induced by LPS, and that Bach2, a transcriptional repressor of B cell terminal differentiation, was a novel target of miR30b. These findings suggest that Kyn can serve as a novel and effective suppressive adjuvant for vaccines. PMID:24583631

    Since the discovery of the human T cell-defined tumor antigen, the cancer immunotherapy field has rapidly progressed, with the research and development of cancer immunotherapy, including cancer vaccines, being conducted actively. However, the disadvantages of most cancer vaccines include relatively weak immunogenicity and immune escape or exhaustion. Adjuvants with innate immunostimulatory activities have been used to overcome these issues, and these agents have been shown to enhance the immunogenicity of cancer vaccines and to act as mono-therapeutic anti-tumor agents. CpG ODN, an agonist for TLR9, is one of the promising nucleic acid-based adjuvants, and it is a potent inducer of innate immune effector functions. CpG ODN suppresses tumor growth in the absence of tumor antigens and peptide administration. Therefore, CpG ODN is expected to be useful as a cancer vaccine adjuvant as well as a cancer immunotherapy agent. In this review, we discuss the potential therapeutic applications and mechanisms of CpG ODN for cancer immunotherapy.

    Most vaccines for protection against Mycoplasma bovis disease are made of bacterins, and they offer varying degrees of protection. Our focus is on the development of a subunit-based protective vaccine, and to that end, we have identified 10 novel vaccine candidates. After formulation of these candidates with TriAdj, an experimental tri-component novel vaccine adjuvant developed at VIDO-InterVac, we measured humoral and cell-mediated immune responses in vaccinated animals. In addition, we compared the immune responses after formulation with TriAdj with the responses measured in animals vaccinated with a mix of a commercial adjuvant (Emulsigen™) and 2 of the components of the TriAdj, namely polyinosinic:polycytidylic acid (poly I:C) and the cationic innate defense regulator (IDR) peptide 1002 (VQRWLIVWRIRK). In this latter trial, we detected significant IgG1 humoral immune responses to 8 out of 10 M. bovis proteins, and IgG2 responses to 7 out of 10 proteins. Thus, we concluded that the commercial adjuvant formulated with poly I:C and the IDR peptide 1002 is the best formulation for the experimental vaccine. PMID:27105454

    Most vaccines require adjuvants for antigen stabilization and immune potentiation. Aluminum-based adjuvants are the most widely used adjuvants for human vaccines. Previous reports demonstrated the preservation of antigen conformation and other antigen characteristics after recovery from adjuvanted Hepatitis B and human papillomavirus vaccines. In this study, we used a combination of various physiochemical and immunochemical methods to analyze hepatitis E vaccine antigen quality attributes after recovery from adjuvants. All biochemical and biophysical methods showed similar characteristics of the p239 protein after recovery from adjuvanted vaccine formulation compared to the antigen in solution which never experienced adsorption/desorption process. Most importantly, we demonstrated full preservation of key antigen epitopes post-recovery from adjuvanted vaccine using a panel of murine monoclonal antibodies as exquisite probes. Antigenicity of p239 was probed with a panel of 9 mAbs using competition/blocking ELISA, surface plasmon resonance and sandwich ELISA methods. These multifaceted analyses demonstrated the preservation of antigen key epitopes and comparable protein thermal stability when adsorbed on adjuvants or of the recovered antigen post-dissolution treatment. A better understanding of the antigen conformation in adjuvanted vaccine will enhanced our knowledge of antigen-adjuvant interactions and facilitate an improved process control and development of stable vaccine formulation.

  3. External validation of Adjuvant! Online breast cancer prognosis tool. Prioritising recommendations for improvement.

    Full Text Available BACKGROUND: Adjuvant! Online is a web-based application designed to provide 10 years survival probability of patients with breast cancer. Several predictors have not been assessed in the original Adjuvant! Online study. We provide the validation of Adjuvant! Online algorithm on two breast cancer datasets, and we determined whether the accuracy of Adjuvant! Online is improved with other well-known prognostic factors. PATIENTS AND METHODS: The French data set is composed of 456 women with early breast cancer. The Dutch data set is composed of 295 women less than 52 years of age. Agreement between observation and Adjuvant! Online prediction was checked, and logistic models were performed to estimate the prognostic information added by risk factors to Adjuvant! Online prediction. RESULTS: Adjuvant! Online prediction was overall well-calibrated in the French data set but failed in some subgroups of such high grade and HER2 positive patients. HER2 status, Mitotic Index and Ki67 added significant information to Adjuvant! Online prediction. In the Dutch data set, the overall 10-year survival was overestimated by Adjuvant! Online, particularly in patients less than 40 years old. CONCLUSION: Adjuvant! Online needs to be updated to adjust overoptimistic results in young and high grade patients, and should consider new predictors such as Ki67, HER2 and Mitotic Index.

  4. Water and stability of pharmaceutical solids

    Shalaev, Evgenyi

    2007-03-01

    Solid pharmaceuticals are multi-component systems consisting of an active pharmaceutical ingredient (API) and inactive ingredients (excipients). Excipients may include inorganic salts (e.g., NaCl), carbohydrates (e.g., lactose), and polymers, to name a few, whereas APIs range from relatively simple molecules (e.g., aspirin) to proteins and olygonucleotides. Pharmaceutical solids could exist either as single-phase or heterophase systems. They also may have different extent of order, such as highly ordered crystalline phases, amorphous solids that are thermodynamically unstable but might be kinetically stable under the time frame of observation, and crystalline mesophases including liquid crystals. With all this diversity, there are common features for such systems, and two of them will be discussed in the presentation. (i) Requirements for chemical stability of pharmaceuticals are very strict. A very limited (e.g., less than 0.1%) extent of conversion is allowed in these materials over the shelf life, i.e., during several years of storage at ambient and (sometimes) not fully controlled (e.g., a medicine cabinet in one's bathroom) conditions. (ii) All pharmaceutical solids contain some water, although its amount and physical state are highly variable and may change during manufacturing and shelf life. There are many challenging questions and issues associated with the ``Water and stability of pharmaceutical solids'' subject; some of them will be considered in the presentation: (i) What are the features of chemical reactivity of crystalline vs disordered systems? (ii) What is the role of water in solid state chemical reactivity of amorphous solids, e.g., water as plasticizer vs reactant vs reaction media? (iii) How homogeneous are pharmaceutical amorphous solid solutions, e.g., carbohydrate-water systems? (iv) What is the optimal water content? With water being the most common destabilizing factor, is ``the drier - the better'' always the case?

    Most infections occur in early life, prompting development of novel adjuvanted vaccines to protect newborns and infants. Several Toll-like receptor (TLR) agonists (TLRAs) are components of licensed vaccine formulations or are in development as candidate adjuvants. However, the type and magnitude of immune responses to TLRAs may vary with the TLR activated as well as age and geographic location. Most notably, in newborns, as compared to adults, the immune response to TLRAs is polarized with lower Th1 cytokine production and robust Th2 and anti-inflammatory cytokine production. The ontogeny of TLR-mediated cytokine responses in international cohorts has been reported, but no study has compared cytokine responses to TLRAs between U.S. neonates and infants at the age of 6months. Both are critical age groups for the currently pediatric vaccine schedule. In this study, we report quantitative differences in the production of a panel of 14 cytokines and chemokines after in vitro stimulation of newborn cord blood and infant and adult peripheral blood with agonists of TLR4, including monophosphoryl lipid A (MPLA) and glucopyranosyl lipid Adjuvant aqueous formulation (GLA-AF), as well as agonists of TLR7/8 (R848) and TLR9 (CpG). Both TLR4 agonists, MPLA and GLA-AF, induced greater concentrations of Th1 cytokines CXCL10, TNF and Interleukin (IL)-12p70 in infant and adult blood compared to newborn blood. All the tested TLRAs induced greater infant IFN-α2 production compared to newborn and adult blood. In contrast, CpG induced greater IFN-γ, IL-1β, IL-4, IL-12p40, IL-10 and CXCL8 in newborn than in infant and adult blood. Overall, to the extent that these in vitro studies mirror responses in vivo, our study demonstrates distinct age-specific effects of TLRAs that may inform their development as candidate adjuvants for early life vaccines.

    Full Text Available Lubrication plays a key role in successful manufacturing of pharmaceutical solid dosage forms; lubricants are essential ingredients in robust formulations to achieve this. Although many failures in pharmaceutical manufacturing operations are caused by issues related to lubrication, in general, lubricants do not gain adequate attention in the development of pharmaceutical formulations. In this paper, the fundamental background on lubrication is introduced, in which the relationships between lubrication and friction/adhesion forces are discussed. Then, the application of lubrication in the development of pharmaceutical products and manufacturing processes is discussed with an emphasis on magnesium stearate. In particular, the effect of its hydration state (anhydrate, monohydrate, dihydrate, and trihydrate and its powder characteristics on lubrication efficiency, as well as product and process performance is summarized. In addition, the impact of lubrication on the dynamics of compaction/compression processes and on the mechanical properties of compacts/tablets is presented. Furthermore, the online monitoring of magnesium stearate in a blending process is briefly mentioned. Finally, the chemical compatibility of active pharmaceutical ingredient (API with magnesium stearate and its reactive impurities is reviewed with examples from the literature illustrating the various reaction mechanisms involved.

    As one of its aspects, the process of European integration has an influence on the legal orders of the Member States, which is often referred to in the literature as the europeization of law. Upon Poland's accession to the structures of the European Union, there have also been radical changes to the Polish legal system. According to the concept of the sources of law in the Polish Constitution and to the judicial decisions of the European Court of Justice, Community law now takes priority over national law, even over acts of parliament. Pharmaceutical law represents one of the areas where the harmonization process has been taking place. It shapes the principles and the manner according to which medicinal products are approved for marketing, the conditions of clinical trials, as well as the conditions of drug manufacture and advertisement. It also determines the rules of trading in medicinal products, the running of pharmaceutical wholesalers and pharmacies, as well as the duties and rights of the Pharmaceutical Inspectorate. This paper provides a summary of research on the impact of Community law on Polish pharmaceutical law, i.e. on the europeization process, and on the consequences of this process for the Polish pharmaceutical market and for research and development.

    1989-01-01

    The ability of aseptically filled pharmaceuticals to support microbial growth was tested on 43 small-volume products (mainly parenterals). These were inoculated with a variety of microorganisms which were known to be associated with contamination of pharmaceutical products. In general, Gram-negative bacteria were found to be much more likely to grow than Gram-positive. It was possible for an inoculum of a few cells to multiply to levels up to 10(7)/mL. The presence of preservatives also influenced the likelihood of growth, 12 out of 19 (63%) of the pharmaceuticals without preservatives supporting growth of one or more microorganisms; only 3 out of 24 (12%) of those with preservatives supported growth. The importance of these observations is discussed with reference to formulation of aseptically filled products, environmental sampling and the quality of cleanroom conditions necessary for production. It is suggested that those pharmaceuticals which are designed to be sterile but not to be terminally sterilized, should be tested before production begins, for their ability to support microbial growth. In this way, the risks involved in aseptically filling can be ascertained. A test is proposed in which "indicator" microorganisms would predict the likelihood of pharmaceutical formulations supporting growth.

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

    Objective: Present the results of the 1995 World Overview which will be held in Oxford England two weeks before ASTRO. Discuss the interpretation and application of these results. Review current research topics on the use of adjuvant endocrine and chemotherapy for early breast cancer. The survival benefits from adjuvant chemotherapy in premenopausal women and adjuvant tamoxifen in postmenopausal women are well established. Each will reduce the annual odds of death by about 25% resulting in a 10 year survival difference of 8-10%. By the time of this presentation, the results of the 1995 Adjuvant Therapy Overview should be with 10+ years of follow-up, and if possible these will be summarized. Current efforts to improve on previous results are focused on the following areas: Optimal chemotherapy dose. Decreasing dose will compromise patient survival. It is not as certain that increasing dose will have as much impact in improving survival. The NSABP was unable to demonstrate an improvement in survival by modestly increasing the dose of cyclophosphamide alone. However, recent results of a Canadian study of CEF (cyclophosphamide, epidoxorubicin, and 5-fluorouracil) and an Intergroup trial of an intense 16 week polychemotherapy program keep alive the possibility that dose escalation is still a very important question. An NSABP trial evaluating even greater cyclophosphamide dose escalation, an Intergroup evaluation of different doxorubicin doses, and two Intergroup trials evaluating very high dose chemotherapy and bone marrow transplantation should provide definitive evidence regarding the importance of dose. Drug sequence. A study from Milan suggests that initial treatment with single agent doxorubicin followed by CMF will be superior to alternating doxorubicin and CMF. This has not been confirmed yet, and the reason for increased benefit from such a sequence is not entirely clear. This concept is being explored further in an Intergroup trial comparing four cycles of

Selecting a good name is not always easy. In fact, there are now professional companies to help finding proper names for medical organizations and medications [1]. These were of help in naming pharmaceutical companies. For instance; ”Zeneca” was an invented name created by the branding consultancy Interbrand. Interbrand had been instructed to find a name which began with a letter from either the top or bottom of the alphabet and was phonetically memorable, of no more than three syllables and did not have an offensive meaning in any language. However, using the names of the founders (eponyms is a common type of naming pharmaceuticals companies.

    The pharmaceutical industry is under increasing pressure on many fronts, from investors requiring larger returns to consumer groups and health authorities demanding cheaper and safer drugs. It is also feeling additional pressure from the infringement upon its profit margins by generic drug producers. Many companies are aggressively pursuing outsourcing contracts in an attempt to counter many of the financial pressures and streamline their operations. At the same time, the productivity of the pharmaceutical industry at its science base is being questioned in terms of the number of products and the timeframes required for each company to deliver them to market. This has generated uncertainties regarding the current corporate strategies that have been adopted and the levels of innovation being demonstrated. In this essay we discuss these topics in the context of the global pharmaceutical market, investigating the basis for many of these issues and highlighting the hurdles the industry needs to overcome, especially as they relate to the chemical sciences.

  15. On radiation treatment of pharmaceutical products

    International Nuclear Information System (INIS)

    The progress made in the GDR over the past decade in the field of radiosterilization of products of the medical industry, has naturally raised the question of radiosterilization in pharmaceutics. However, because of the diversity and complicated nature of pharmaceutical products and, consequently, longer periods of time required for preliminary studies, their radiosterilization has not yet been applied on an industrial scale, in contrast to the situation in the medical industry. The studies carried out so far have been mainly concerned with ascertaining the permissibility and effectiveness of radiosterilization of individual products under particular conditions rather than with laying down a broad theoretical basis. Accordingly, the present paper does not describe results of special studies but presents a brief rewiev of some studies on radiation treatment of pharmaceutical products undertaken in the GDR.

    Marketing concepts as a mechanism to help pharmacy develop, communicate, and sell future pharmaceutical services to consumers are discussed. Pharmacy as a profession must define itself broadly to take advantage of future growth opportunities. These growth opportunities will be realized from unmet health-care needs and changing consumer life style trends and values. New services must therefore be oriented toward consumers (i.e., patients, health professionals, and third-party agencies) to gain acceptance. Dispensing and drug-knowledge-distribution pharmaceutical services are reviewed by a product life cycle analysis of sales profits versus time. A marketing mix for new pharmaceutical services is developed consisting of service, price, distribution, and promotion strategies. Marketing can encompass those key elements necessary to meet the organizational goals of pharmacy and provide a systematic, disciplined approach for presenting a new service to consumers.

    In this study, terahertz time-domain spectroscopic (THz-TDS) technique has been used to ascertain the change in the optical properties, as a function of changing porosity and mass fraction of active pharmaceutical ingredient (API), of training sets of pharmaceutical tablets. Four training sets of pharmaceutical tablets were compressed with microcrystalline cellulose (MCC) excipient and indomethacin API by varying either the porosity, height, and API mass fraction or all three tablet parameters. It was observed, as far as we know, for the first time, that the THz time-domain and frequency-domain effective refractive index, as well as, the frequency-domain effective absorption coefficient both show linear correlations with the porosity and API mass fraction for training sets of real pharmaceutical tablets. We suggest that, the observed linear correlations can be useful in basic research and quality inspection of pharmaceutical tablets. Additionally, we propose a novel optical strain parameter, based on THz measurement, which yields information on the conventional strain parameter of a tablet as well as on the change of fill fraction of solid material during compression of porous pharmaceutical tablets. We suggest that the THz measurement and proposed method of data analysis, in addition to providing an efficient tool for basic research of porous media, can serve as one of the novel quality by design (QbD) implementation techniques to predict critical quality attributes (CQA) such as porosity, API mass fraction and strain of flat-faced pharmaceutical tablets before production.

  7. Radiostability of pharmaceuticals under different irradiation conditions

    International Nuclear Information System (INIS)

    In this paper, the products studied are cefazolin, glucagon and dobutamine HCl. The radioresistance of pharmaceuticals may depend on the conditions of irradiation. The best is to irradiate the drugs in solid state and the chemical transformations can be reduced also by lowering the temperature of the liquid. In solid state, the dose rate has no influence on the decomposition for the selected molecules and it should be noted that drug excipients selected for bioavailability reasons are not always radioprotectors. These results are important from a technical point of view in pharmaceutical industry

    Pharmaceutical industry has been experiencing a difficult time over the last few years. Despite record high investment on R&D,the overall productivity reached a historic low level. The growth rate of pharmaceutical industry based on total sales hit a low of 9% in 2002, a sharp decline from double-digit growth rates in late 1990s. A shortage of good new drugs in the pipeline, the imminent patent expirations on blockbuster drugs, and fierce competitions from generic drugs are major challenges.

  9. The uncertainty budget in pharmaceutical industry

    DEFF Research Database (Denmark)

    Measurements in a pharmaceutical industry are usually carried out to ascertain the quality of a product or the control of a process; in either case the measurement result serves to demonstrate that the value of the measurand is within specified limits. No method is without bias, and no result...... of their uncertainty, exactly as described in GUM [2]. Pharmaceutical industry has therefore over the last 5 years shown increasing interest in accreditation according to ISO 17025 [3], and today uncertainty budgets are being developed for all so-called critical measurements.

  10. Adjuvants and immunostimulants in fish vaccines: current knowledge and future perspectives.

    Vaccination is the most adequate method to control infectious diseases that threaten the aquaculture industry worldwide. Unfortunately, vaccines are usually not able to confer protection on their own; especially those vaccines based on recombinant antigens or inactivated pathogens. Therefore, the use of adjuvants or immunostimulants is often necessary to increase the vaccine efficacy. Traditional adjuvants such as mineral oils are routinely used in different commercial bacterial vaccines available for fish; however, important side effects may occur with this type of adjuvants. A search for alternative molecules or certain combinations of them as adjuvants is desirable in order to increase animal welfare without reducing protection levels. Especially, combinations that may target specific cell responses and thus a specific pathogen, with no or minor side effects, should be explored. Despite this, the oil adjuvants currently used are quite friendlier with respect to side effects compared with the oil adjuvants previously used. The great lack of fish antiviral vaccines also evidences the importance of identifying optimal combinations of a vaccination strategy with the use of a targeting adjuvant, especially for the promising fish antiviral DNA vaccines. In this review, we summarise previous studies performed with both traditional adjuvants as well as the most promising new generation adjuvants such as ligands for Toll receptors or different cytokines, focussing mostly on their protective efficacies, and also on what is known concerning their effects on the fish immune system when delivered in vivo.

  11. Treg inducing adjuvants for therapeutic vaccination against chronic inflammatory diseases

    2013-08-01

    Full Text Available Many existing therapies in autoimmune diseases are based on systemic suppression of inflammation, the observed side effects illustrate the need for more specific interventions. Regulatory T cells (Treg are pivotal controllers of (autoaggressive immune responses, and decreased Treg numbers and/or functioning have been associated with autoimmune disease. Especially antigen-specific targeting of Treg would enable tailor made interventions, while obviating negative side effects of general immuno-suppression. Self-antigens that participate in inflammation, irrespective of the etiology of the different autoimmune diseases, are held to be candidate antigens for such interventions. Rather than tolerance induction to disease inciting self-antigens, which are frequently unknown, general self-antigens expressed at sites of inflammation would allow targeting of disease independent, but inflammatory-site specific, regulatory mechanisms. Preferably, such self-antigens should be abundantly expressed and up-regulated at the inflammatory site. Heat shock proteins show several of these characteristics.The development of antigen-specific Treg inducing vaccines is a major novel goal in the field of immunotherapy in autoimmune diseases. Progress is hampered by the lack of effective antigens and by the fact that other factors such as dose, route and the presence or absence of an adjuvant, turned out to be critical unknowns, with respect to effective induction of Treg. The use of a Treg inducing adjuvant might be required to achieve effective regulatory responses, in the case of ongoing inflammation. Future goals will be the optimization of natural Treg expansion (or the induction of adaptive Treg without loss of their suppressive function or the concomitant induction of non-regulatory T cells. Here, we discuss the potential use of protein/peptide-based vaccines combined with Treg inducing adjuvants for the development of therapeutic vaccines against chronic

  2. Deep pharma: psychiatry, anthropology, and pharmaceutical detox.

    2014-06-01

    Psychiatric medication, or psychotropics, are increasingly prescribed for people of all ages by both psychiatry and primary care doctors for a multitude of mental health and/or behavioral disorders, creating a sharp rise in polypharmacy (i.e., multiple medications). This paper explores the clinical reality of modern psychotropy at the level of the prescribing doctor and clinical exchanges with patients. Part I, Geographies of High Prescribing, documents the types of factors (pharmaceutical-promotional, historical, cultural, etc.) that can shape specific psychotropic landscapes. Ethnographic attention is focused on high prescribing in Japan in the 1990s and more recently in the Upper Peninsula of Michigan, in the US. These examples help to identify factors that have converged over time to produce specific kinds of branded psychotropic profiles in specific locales. Part II, Pharmaceutical Detox, explores a new kind of clinical work being carried out by pharmaceutically conscious doctors, which reduces the number of medications being prescribed to patients while re-diagnosing their mental illnesses. A high-prescribing psychiatrist in southeast Wisconsin is highlighted to illustrate a kind of med-checking taking place at the level of individual patients. These various examples and cases call for a renewed emphasis by anthropology to critically examine the "total efficacies" of modern pharmaceuticals and to continue to disaggregate mental illness categories in the Boasian tradition. This type of detox will require a holistic approach, incorporating emergent fields such as neuroanthropology and other kinds of creative collaborations.

    2014-06-01

    The ubiquity of Online Social Networks (OSNs) is creating new sources for healthcare information, particularly in the context of pharmaceutical drugs. We aimed to examine the impact of a given OSN's characteristics on the content of pharmaceutical drug discussions from that OSN. We compared the effect of four distinguishing characteristics from ten different OSNs on the content of their pharmaceutical drug discussions: (1) General versus Health OSN; (2) OSN moderation; (3) OSN registration requirements; and (4) OSNs with a question and answer format. The effects of these characteristics were measured both quantitatively and qualitatively. Our results show that an OSN's characteristics indeed affect the content of its discussions. Based on their information needs, healthcare providers may use our findings to pick the right OSNs or to advise patients regarding their needs. Our results may also guide the creation of new and more effective domain-specific health OSNs. Further, future researchers of online healthcare content in OSNs may find our results informative while choosing OSNs as data sources. We reported several findings about the impact of OSN characteristics on the content of pharmaceutical drug discussion, and synthesized these findings into actionable items for both healthcare providers and future researchers of healthcare discussions on OSNs. Future research on the impact of OSN characteristics could include user demographics, quality and safety of information, and efficacy of OSN usage. PMID:24637141

  15. Who Benefits From Adjuvant Radiation Therapy for Gastric Cancer? A Meta-Analysis

    International Nuclear Information System (INIS)

    Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated from survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy

    Full Text Available In recent years, concerns about the occurrence and fate of pharmaceuticals that could be present in water and wastewater has gained increasing attention. With the public’s enhanced awareness of eco-safety, environmentally benign methods based on microorganisms have become more accepted methods of removing pollutants from aquatic systems. This study investigates bioremediation of pharmaceutical wastewater from pharmaceutical company Pliva Hrvatska d.o.o., using activated sludge and bioaugmented activated sludge with isolated mixed bacterial culture. The experiments were conducted in a batch reactor in submerged conditions, at initial concentration of organic matter in pharmaceutical wastewater, expressed as COD, 5.01 g dm–3 and different initial concentrations of activated sludge, which ranged from 1.16 to 3.54 g dm–3. During the experiments, the COD, pH, concentrations of dissolved oxygen and biomass were monitored. Microscopic analyses were performed to monitor the quality of activated sludge. Before starting with the bioremediation in the batch reactor, toxicity of the pharmaceutical wastewater was determined by toxicity test using bacteria Vibrio fischeri. The obtained results showed that the effective concentration of the pharmaceutical wastewater was EC50 = 17 % and toxicity impact index was TII50 = 5.9, meaning that the untreated pharmaceutical industrial effluent must not be discharged into the environment before treatment. The results of the pharmaceutical wastewater bioremediation process in the batch reactor are presented in Table 1. The ratio γXv ⁄ γX maintained high values throughout all experiments and ranged from 0.90 and 0.95, suggesting that the concentrations of biomass remained unchanged during the experiments. The important kinetic parameters required for performance of the biological removal process, namely μmax, Ks, Ki, Y and kd were calculated from batch experiments (Table 2.

    2003-09-01

    After the turn to market oriented economy a lot of drugs were authorized for sale in the East European countries. Because of the limited resources of these countries, mainly generic or brand generic products were licensed. The number of the patented drugs on the market could be used as measure of the market attractiveness to the R&D producers. The study shows the analysis of the innovativeness of the Bulgarian drug market comparing the registration and the patient activity of the producers. The number of the authorized products for five years period (1990-2000) and share of the patented products were investigated. During the observed period the number of newly authorized pharmaceuticals increased almost seven times from 800 (650 INN) to 6000 (2000 INN) dosage forms. The prevailing part of the newly registered drugs was found to be brand generics and possess only trade name protection. The share of drugs that are patented is less than five percent of all newly registered medicines, and among the fifty most commonly prescribed and sold medicines between 1996-2000, only 0.5 percent of drugs were patented. Obviously the Bulgarian pharmaceutical market is very competitive but not that attractive for most of the R&D producers. In general the registration of the patent protected products is increasing during the years and especially after harmonization of the related legislation with the EU requirements. The patent activity of the pharmaceutical companies regarding newly authorized drugs is influenced by the structure of morbidity and population. During the last two years the patent activity is increasing and is oriented mainly towards the protection of newly authorized drugs or pharmaceutical forms and obligatory registration of trademarks for the privatized Bulgarian pharmaceutical manufacturers.

    Full Text Available DNA vaccines can induce both humoral and cellular immune responses. Although some DNA vaccines are already licensed for infectious diseases in animals, they are not licensed for human use because the risk and benefit of DNA vaccines is still controversial. Indeed, in humans, the immunogenicity of DNA vaccines is lower than that of other traditional vaccines. To develop the use of DNA vaccines in the clinic, various approaches are in progress to enhance or improve the immunogenicity of DNA vaccines. Recent studies have shown that immunogenicity of DNA vaccines are regulated by innate immune responses via plasmid DNA recognition through the STING-TBK1 signaling cascade. Similarly, molecules that act as dsDNA sensors that activate innate immune responses through STING-TBK1 have been identified and used as genetic adjuvants to enhance DNA vaccine immunogenicity in mouse models. However, the mechanisms that induce innate immune responses by DNA vaccines are still unclear. In this review, we will discuss innate immune signaling upon DNA vaccination and genetic adjuvants of innate immune signaling molecules.

  9. Adjuvant chemoradiotherapy for adenocarcinoma of the stomach. A new progress?

    International Nuclear Information System (INIS)

    Frequency of local and distant failures after gastrectomy has led to extended lymph nodes dissection to obtain a better locoregional control. However, five year survival rates were not significantly different between patients undergoing D2 and D1 lymphadenectomy, and higher morbidity and post operative deaths were reported in large randomized trials (respectively 25% vs 48% and 4 vs 13%). Additionally, several met-analysis failed to demonstrate a significant survival advantage with adjuvant chemotherapy. The results of the first trial demonstrating one advantage to adjuvant post-operative chemoradiotherapy should modify the standard care. Disease free and overall survival after surgery alone and after surgery and concurrent chemoradiotherapy were respectively 31% vs 48% and 41% vs 50%. The inter-group trial demonstrate that better local control improve survival if radiation fields include stamps, tumour bed, proximal nodal chains and nodes corresponding to D2 extended lymph nodes dissection. Treatment was feasible with few severe toxic effects (1%). Of the 281 patients, 17% stopped treatment because toxic effects. Technical modalities of radiotherapy and post-operative nutrition support which are critical points of interest for this treatment, are also discussed. (authors)

    2012-07-01

    Adjuvant arthritis is an animal model that closely resembles rheumatoid arthritis in humans. It is a successful working model used to study new anti-inflammatory agents. In previous studies (animal and clinical) we have shown that evening primrose oil, fish oil and the methanol extract of date fruits and fenugreek seeds have anti-inflammatory activity and that the methanol extract of dates has an antioxidant effect. Based on these studies, the aim of the present study was to prepare 7 functional foods containing such bioactive fractions separately or in combination and to evaluate them in adjuvant arthritis in rats, study the stability of bioactive ingredients and evaluate their sensory properties. The studied biochemical parameters were erythrocyte sedimentation rate, erythrocyte superoxide dismutase, glutathione peroxidase and plasma copper, zinc and interlukin 2. Nutritional parameters, including body weight gain, food intake and food efficiency ratio were monitored during the feeding of the functional foods. The bioactive ingredients assessed were total phenolic contents and fatty acids. The results showed improvement in the biochemical parameters, body weight gain and food efficiency ratio of arthritic rats fed on the functional foods with different degrees. All the prepared functional foods were sensory accepted. The active ingredients showed stability during storage. In conclusion, all the tested functional foods showed promising antiinflammatory activity and were determined to be acceptable through sensory evaluation which means that their potential beneficial use as dietary supplements in rheumatoid arthritis patients may be recommended.

    1994-11-01

    The therapeutic value of regular physical exercise for patients with atopic eczema (AE) and other chronic inflammatory dermatoses has not yet been investigated systematically. At our institution an adjuvant group sports programme for voluntary inpatients has been in place for 3 years. Using a standardized questionnaire we found positive psychological influences of this program on the patients' mood and psychosocial wellbeing. Since most dermatologists, however, regard sweating as detrimental for patients with AE, we studied the impact of regular sports activities on the skin condition of AE-patients otherwise subdued to usual dermatotherapy (yet without corticosteroids) by aid of a standardized symptomscore system. Thirty inpatients with AE participated regularly in the sports programme, another 30 inpatients with AE (the control group) did not. The skin condition improved similarly the two groups over the study period of about 3 weeks. Cutaneous thermoregulation (with one arm in a 41 degrees C water bath as thermic stimulus) was examined in patients with AE before and after the study period. While many AE patients initially showed paradoxical, i.e. decreasing, skin temperature in the contralateral arm, after 3 weeks of physical training most of the participants had normalized consensual, i.e. increased, temperature reaction to the same warmth exposure. The conclusion is drawn that regular sports may be of adjuvant therapeutic value in patients suffering from AE, except in the acute stages of the disease. PMID:7822198

  13. Adjuvant radiation therapy in metastatic lymph nodes from melanoma

    International Nuclear Information System (INIS)

    To analyze the outcome after adjuvant radiation therapy with standard fractionation regimen in metastatic lymph nodes (LN) from cutaneous melanoma. 86 successive patients (57 men) were treated for locally advanced melanoma in our institution. 60 patients (69%) underwent LN dissection followed by radiation therapy (RT), while 26 patients (31%) had no radiotherapy. The median number of resected LN was 12 (1 to 36) with 2 metastases (1 to 28). Median survival after the first relapse was 31.8 months. Extracapsular extension was a significant prognostic factor for regional control (p = 0.019). Median total dose was 50 Gy (30 to 70 Gy). A standard fractionation regimen was used (2 Gy/fraction). Median number of fractions was 25 (10 to 44 fractions). Patients were treated with five fractions/week. Patients with extracapsular extension treated with surgery followed by RT (total dose ≥50 Gy) had a better regional control than patients treated by surgery followed by RT with a total dose <50 Gy (80% vs. 35% at 5-year follow-up; p = 0.004). Adjuvant radiotherapy was able to increase regional control in targeted sub-population (LN with extracapsular extension)

    Full Text Available During last decades, diphtheria has remained as a serious disease that still outbreaks and can occur worldwide. Recently, new vaccine delivery systems have been developed by using the biodegradable and biocompatible polymers such as alginate. Alginate nanoparticles as a carrier with adjuvant and prolong release properties that enhance the immunogenicity of vaccines. In this study diphtheria toxoid loaded nanoparticles were prepared by ionic gelation technique and characterized with respect to size, zeta potential, morphology, encapsulation efficiency, release profile, and immunogenicity. Appropriate parameters (calcium chloride and sodium alginate concentration, homogenization rate and homogenization time redounded to the formation of suitable nanoparticles with a mean diameter of 70±0.5 nm. The loading studies of the nanoparticles resulted in high loading capacities (>90% and subsequent release studies showed prolong profile. The stability and antigenicity of toxoid were evaluated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and ouchterlony test and proved that the encapsulation process did not affect the antigenic integrity and activity. Guinea pigs immunized with the diphtheria toxoid-loaded alginate nanoparticles showed highest humoral immune response than conventional vaccine. It is concluded that, with regard to the desirable properties of nanoparticles and high immunogenicity, alginate nanoparticles could be considered as a new promising vaccine delivery and adjuvant system.

  15. Suppressive effects of QFGJS, a preparation from an anti-arthritic herbal formula, on rat experimental adjuvant-induced arthritis

    International Nuclear Information System (INIS)

    To analyze the anti-arthritic effects of QFGJS (a pharmaceutical preparation from herbs) on rheumatoid arthritis, adjuvant-induced arthritis (AIA) was established in male SD rats, and two administration protocols, i.e., oral treatment with different doses of QFGJS on the day of arthritis induction or on the day when visible clinical signs of arthritis occurred, were initiated and continued until day 30. Treatments with QFGJS using both administration protocols significantly suppressed the incidence and severity of arthritis in a dose-dependent manner, showing dramatic reduction of paw swelling and ESR throughout the disease progression of AIA. Radiological and histopathological examinations showed markedly decreased tissue and bone destruction of ankle joints in the QFGJS-treated rats. The serum levels of TNF-α, IL-1β, and IL-6 were significantly decreased in the QFGJS-treated rats. QFGJS demonstrates pronounced anti-arthritic effects on AIA, indicating that this herbal preparation would be a potent candidate as a novel botanical drug for further investigation

  16. Unraveling molecular signatures of immunostimulatory adjuvants in the female genital tract through systems biology.

    Full Text Available Sexually transmitted infections (STIs unequivocally represent a major public health concern in both industrialized and developing countries. Previous efforts to develop vaccines for systemic immunization against a large number of STIs in humans have been unsuccessful. There is currently a drive to develop mucosal vaccines and adjuvants for delivery through the genital tract to confer protective immunity against STIs. Identification of molecular signatures that can be used as biomarkers for adjuvant potency can inform rational development of potent mucosal adjuvants. Here, we used systems biology to study global gene expression and signature molecules and pathways in the mouse vagina after treatment with two classes of experimental adjuvants. The Toll-like receptor 9 agonist CpG ODN and the invariant natural killer T cell agonist alpha-galactosylceramide, which we previously identified as equally potent vaginal adjuvants, were selected for this study. Our integrated analysis of genome-wide transcriptome data determined which signature pathways, processes and networks are shared by or otherwise exclusive to these 2 classes of experimental vaginal adjuvants in the mouse vagina. To our knowledge, this is the first integrated genome-wide transcriptome analysis of the effects of immunomodulatory adjuvants on the female genital tract of a mammal. These results could inform rational development of effective mucosal adjuvants for vaccination against STIs.

    Adjuvants are essential to boost the immune response to inoculated antigen and play a central role in vaccine development. In this study, we investigated the efficacy of several adjuvants in the production of anti-bovine serum albumin (BSA) antibodies in silver catfish. Two hundred and seventy juvenile silver catfish (60-80 g) of both sexes were intraperitoneally vaccinated with BSA (200 µg/fish) alone or mixed to the following adjuvants: Freund's complete adjuvant (FCA), Freund's incomplete adjuvant (FIA), aluminum hydroxide (AlOH), Montanide, four types of cytosine-phosphate-guanine (CpG) oligodeoxynucleotides (ODNs) and three concentrations of β-glucan, and the immune enhancing property was evaluated by measuring anti-BSA antibodies in blood samples at biweekly intervals. Our results demonstrated that CpGs ODNs and β-glucan were as effective as classical adjuvants (FCA, FIA, AlOH and Montanide) in promoting anti-BSA antibodies and that the kinetics of antibody production induced by all adjuvants used in our study had a similar trend to that observed in other fish species, with a peak at 28 days post-vaccination. These results may be useful for the selection of adjuvants for vaccine formulation intended for silver catfish and for the development of vaccine and vaccination strategies to other fish species.

    Aluminium oxyhydroxide, Al(OH)3 is one of few compounds approved as an adjuvant in human vaccines. However, the mechanism behind its immune stimulating properties is still poorly understood. In vitro co-culture of an aluminium adjuvant and the human monocytic cell line THP-1 resulted in reduced cell proliferation. Inhibition occurred at concentrations of adjuvant several times lower than would be found at the injection site using a vaccine formulation containing an aluminium adjuvant. Based on evaluation of the mitochondrial membrane potential, THP-1 cells showed no mitochondrial rupture after co-culture with the aluminium adjuvant, instead an increase in mitochondrial activity was seen. The THP-1 cells are phagocytosing cells and after co-culture with the aluminium adjuvant the phagosomal pathway was obstructed. Primary or early phagosomes mature into phagolysosomes with an internal pH of 4.5 - 5 and carry a wide variety of hydrolysing enzymes. Co-culture with the aluminium adjuvant yielded a reduced level of acidic vesicles and cathepsin L activity, a proteolytic enzyme of the phagolysosomes, was almost completely inhibited. THP-1 cells are an appropriate in vitro model in order to investigate the mechanism behind the induction of a phagocytosing antigen presenting cell into an inflammatory cell by aluminium adjuvants. Much information will be gained by investigating the phagosomal pathway and what occurs inside the phagosomes and to elucidate the ultimate fate of phagocytosed aluminium particles.

  2. Antibody-antigen-adjuvant conjugates enable co-delivery of antigen and adjuvant to dendritic cells in cis but only have partial targeting specificity.

    Directory of Open Access Journals (Sweden)

    Martin Kreutz

    Full Text Available Antibody-antigen conjugates, which promote antigen-presentation by dendritic cells (DC by means of targeted delivery of antigen to particular DC subsets, represent a powerful vaccination approach. To ensure immunity rather than tolerance induction the co-administration of a suitable adjuvant is paramount. However, co-administration of unlinked adjuvant cannot ensure that all cells targeted by the antibody conjugates are appropriately activated. Furthermore, antigen-presenting cells (APC that do not present the desired antigen are equally strongly activated and could prime undesired responses against self-antigens. We, therefore, were interested in exploring targeted co-delivery of antigen and adjuvant in cis in form of antibody-antigen-adjuvant conjugates for the induction of anti-tumour immunity. In this study, we report on the assembly and characterization of conjugates consisting of DEC205-specific antibody, the model antigen ovalbumin (OVA and CpG oligodeoxynucleotides (ODN. We show that such conjugates are more potent at inducing cytotoxic T lymphocyte (CTL responses than control conjugates mixed with soluble CpG. However, our study also reveals that the nucleic acid moiety of such antibody-antigen-adjuvant conjugates alters their binding and uptake and allows delivery of the antigen and the adjuvant to cells partially independently of DEC205. Nevertheless, antibody-antigen-adjuvant conjugates are superior to antibody-free antigen-adjuvant conjugates in priming CTL responses and efficiently induce anti-tumour immunity in the murine B16 pseudo-metastasis model. A better understanding of the role of the antibody moiety is required to inform future conjugate vaccination strategies for efficient induction of anti-tumour responses.

    Vaccine adjuvants are substances associated with antigens that are fundamental to the formation of an intense, durable, and fast immune response. In this context, the use of vaccine adjuvants to generate an effective cellular immune response is crucial for the design and development of vaccines against visceral leishmaniasis. The objective of this study was to evaluate innate inflammatory response induced by the vaccine adjuvants saponin (SAP), incomplete Freund’s adjuvant (IFA), and monophosphoryl lipid A (MPL). After a single dose of adjuvant was injected into the skin of mice, we analyzed inflammatory reaction, selective cell migration, and cytokine production at the injection site, and inflammatory cell influx in the peripheral blood. We found that all vaccine adjuvants were able to promote cell recruitment to the site without tissue damage. In addition, they induced selective migration of neutrophils, macrophages, and lymphocytes. The influx of neutrophils was notable at 12 h in all groups, but at other time points it was most evident after inoculation with SAP. With regard to cytokines, the SAP led to production of interleukin (IL)-2, IL-6, and IL-4. IFA promoted production of tumor necrosis factor (TNF)-α, interferon (IFN)-γ, IL-6, IL-17, IL-4, and IL-10. We also observed that MPL induced high production of IL-2, TNF-α, and IFN-γ, in addition to IL-6, IL-17, and IL-10. In peripheral blood, values of certain cell populations in the local response changed after stimulation. Our data demonstrate that the three vaccine adjuvants stimulate the early events of innate immune response at the injection site, suggesting their ability to increase the immunogenicity of co-administered antigens. Moreover, this work provides relevant information about elements of innate and acquired immune response induced by vaccine adjuvants administered alone. PMID:22829882

    Bento, Dulce; Staats, Herman F; Borges, Olga

    2015-07-17

    Successful vaccine development is dependent on the development of effective adjuvants since the poor immunogenicity of modern subunit vaccines typically requires the use of potent adjuvants and high antigen doses. In recent years, adjuvant formulations combining both immunopotentiators and delivery systems have emerged as a promising strategy to develop effective and improved vaccines. In this study we investigate if the association of the mast cell activating adjuvant compound 48/80 (C48/80) with chitosan nanoparticles would promote an antigen dose sparing effect when administered intranasally. Even though the induction of strong mucosal immunity required higher antigen doses, incorporation of C48/80 into nanoparticles provided significant dose sparing when compared to antigen and C48/80 in solution with no significant effect on serum neutralizing antibodies titers. These results suggest the potential of this novel adjuvant combination to improve the immunogenicity of a vaccine and decrease the antigen dose required for vaccination. PMID:26087299

  8. Pseudo-Mannosylated DC-SIGN Ligands as Potential Adjuvants for HIV Vaccines

    Directory of Open Access Journals (Sweden)

    Angela Berzi

    2014-01-01

    Full Text Available The development of new and effective adjuvants may play a fundamental role in improving HIV vaccine efficacy. New classes of vaccine adjuvants activate innate immunity receptors, notably toll like receptors (TLRs. Adjuvants targeting the C-Type lectin receptor DC-SIGN may be alternative or complementary to adjuvants based on TRL activation. Herein we evaluate the ability of the glycomimetic DC-SIGN ligand Polyman 19 (PM 19 to modulate innate immune responses. Results showed that PM 19 alone, or in combination with TLR agonists, induces the expression of cytokines, β chemokines and co-stimulatory molecules that may, in turn, modulate adaptive immunity and exert anti-viral effects. These results indicate that the suitability of this compound as a vaccine adjuvant should be further evaluated.

  9. Adjuvant Whole Brain Radiotherapy: Strong Emotions Decide But Rational Studies Are Needed

    International Nuclear Information System (INIS)

    Brain metastases are common in cancer patients and cause considerable morbidity and mortality. For patients with limited disease and good performance status, treatment typically involves a combination of focal measures (e.g., surgical resection or radiosurgery) for the radiographically apparent disease, followed by adjuvant whole brain radiotherapy (WBRT) to treat subclinical disease. Because of concerns regarding the toxicity of WBRT, especially neurocognitive deterioration, many have advocated withholding adjuvant WBRT. Recently published studies have shed more light on the efficacy of adjuvant WBRT and the neurocognitive effects of WBRT. However, the inclusion of neurocognitive and quality-of-life data in clinical trials are still required to better define the role of adjuvant WBRT. Currently, two Phase III trials are underway, one in Europe and one in North America, that will determine the effect of adjuvant WBRT on patients' quality of life, neurocognitive function, and survival

    Full Text Available Safe, effective adjuvants that enhance vaccine potency, including induction of neutralizing Abs against a broad range of variant strains, is an important strategy for the development of seasonal influenza vaccines which can provide optimal protection, even during seasons when available vaccines are not well matched to circulating viruses. We investigated the safety and ability of Glucopyranosyl Lipid Adjuvant-Stable Emulsion (GLA-SE, a synthetic Toll-like receptor (TLR4 agonist formulation, to adjuvant Fluzone® in mice and non-human primates. The GLA-SE adjuvanted Fluzone vaccine caused no adverse reactions, increased the induction of T helper type 1 (T(H1-biased cytokines such as IFNγ, TNF and IL-2, and broadened serological responses against drifted A/H1N1 and A/H3N2 influenza variants. These results suggest that synthetic TLR4 adjuvants can enhance the magnitude and quality of protective immunity induced by influenza vaccines.

    Pressure to control pharmaceutical expenditure and price competition among pharmaceutical companies are fuelling the development of generic drug markets in EU countries. However, in Belgium, the market for generic drugs is underdeveloped compared with other countries. To promote the use of generic drugs, the government introduced a reference pricing (RP) scheme in 2001. The aim of this paper is to discuss Belgian pharmaceutical policy regarding generic drugs and to analyse how the Belgian drug market has evolved following initiation of the RP scheme. The market share held by generic drugs increased following implementation of the RP scheme. Focusing on volume, average market share (by semester) for generic drugs amounted to 2.05% of the total pharmaceutical market from January 1998 to June 2001, compared with 6.11% from July 2001 to December 2003. As new generic drugs are introduced, their market share tends to increase in the first couple of months, after which it levels off. Faced with increasing generic competition, some manufacturers have launched new variants of their original drug, thereby effectively extending the period of patent protection. Strategies consisting of price reductions in return for the abolition of prescribing conditions and the launch of new dosages or formulations appear to have been successful in maintaining the market share of original drugs. Nevertheless, the introduction of the RP scheme was associated with savings amounting to 1.8% of pharmaceutical expenditure by the third-party payer in 2001 and 2.1% in 2002. The findings of this paper indicate that the RP scheme has stimulated the Belgian generic drug market. However, existing policy has largely failed to take into account the role that physicians and pharmacists can play in stimulating generic drug use. Therefore, further development of the Belgian generic drug market seems to hinge on the creation of appropriate incentives for physicians to prescribe, and for pharmacists to

    International Nuclear Information System (INIS)

    Polyacrylic acid (PA) and its salts are promising biomaterials used in the pharmaceutical industry. They could be used as pharmaceutical additives, as a burn dressing and also in the slow released implants or trans-derma patch formulations. Polyacrylic acid of pharmaceutical grade can be obtained by gamma irradiation polymerization. The influence of the raw materials and of the technological procedure on the final product purity has been investigated by Instrumental Neutron Activation Analysis (INAA) method. The following materials have been analyzed by INAA: 1) acrylic acid of technical grade; 2) acrylic acid purified by double crystallisation; 3) NaOH of analytical grade; 4) CaCl-2·6H2O of pharmaceutical grade; 5) CaCl2·2H2O of analytical grade; 6) granulated PANa; 7) ungranulated PANa; 8) ungranulated PANaCa; 9) PANaCa granulated by milling in IFIN-HH using the mill nr. 1; 10) PANaCa granulated by milling in Institute of Chemical and Pharmaceutical Research (ICPR); 11) PANaCa granulated by milling in IFIN-HH using the mill nr. 2. The first five samples, marked from 1 to 5, are raw materials and the other six samples, marked from 6 to 11, are the final polyacrylic structures processed by various technological procedures. The samples together with the appropriate reference materials have been irradiated at WWR-S reactor in a neutron flux of 2.5·1012 cm-2s-1 and the induced radioactivity was registered by a HPGe detector (EG/G ORTEC) of 30% efficiency and 2.1 keV resolution. The concentrations of As, Br, Ce, Co, Cr, Fe, La, Sb, Sc, Zn have been determined. For the final polyacrylic structures, except for granulated PANa (sample 6), only the elements Co, Cr, Fe, Sc, Zn were found at the following concentration levels: tens of ppm (Co), ppm (Zn), hundreds of ppb (Cr), tens of ppb (Co), ppb (Co, Sc), 10-1 ppb (Sc). In the granulated PANa, in comparison with the other analyzed final products, similar concentration values were found for Fe, Sc and Zn, higher values

    It has been documented in several studies that soil may be contaminated by human or veterinary pharmaceuticals. Some of pharmaceutical ingredient may be retained in soils. The rest can be transported to the surface and groundwater through surface runoff and infiltration. Mobility of contaminants in soils is dependent on many soil and pharmaceutical properties (e.g. pharmaceutical adsorption on soil particles and pharmaceutical degradation). The goals of this study were: (1) to measure adsorption isotherms of selected pharmaceuticals in one soil; (2) to evaluate degradation of selected pharmaceuticals in this soil, and (3) to evaluate impact of applied pharmaceuticals on biological activity in soil, which influences pharmaceutical decomposition. Batch sorption tests were performed for 7 selected pharmaceuticals (beta blockers Atenolol and Metoprolol, anticonvulsant Carbamazepin, and antibiotics Clarithromycin, Clindamycin, Trimetoprim and Sulfamethoxazol) and one soil (topsoil of Greyic Phaeozem from Čáslav). The same concentrations (0.5, 1, 2.5, 5 and 10 mg/l) were used for almost all pharmaceuticals except Clarithromycin (0.033, 0.08, 0.165, 0.25, 0.33 mg/l). The Freundlich equations were used to describe adsorption isotherms. Degradation of all 7 pharmaceuticals was also studied. Solutes of different pharmaceuticals (concentration of 8.3 mg/l) were added into the plastic bottles (one pharmaceutical per bottle) with soil. Concentrations of pharmaceuticals remaining in soil 1, 2, 5, 12, 23, 40 and 61 days after the pharmaceutical application were analyzed. Colony forming unites were evaluated to describe microbial activity in time affected by different pharmaceuticals. Adsorption of studied pharmaceuticals on soil particles decreasing as follows: Clarithromycin, Trimetoprim, Metoprolol, Clindamycin, Atenolol, Carbamazepin, Sulfamethoxazol. Degradation rates in some degree reflected adsorption of studied pharmaceuticals on soil particles and increased with

    Frequency of local and distant failures after gastrectomy has led to extended lymph nodes dissection to obtain a better locoregional control. However, five year survival rates were not significantly different between patients undergoing D2 and D1 lymphadenectomy, and higher morbidity and post operative deaths were reported in large randomized trials (respectively 25% vs 48% and 4 vs 13%). Additionally, several met-analysis failed to demonstrate a significant survival advantage with adjuvant chemotherapy. The results of the first trial demonstrating one advantage to adjuvant post-operative chemoradiotherapy should modify the standard care. Disease free and overall survival after surgery alone and after surgery and concurrent chemoradiotherapy were respectively 31% vs 48% and 41% vs 50%. The inter-group trial demonstrate that better local control improve survival if radiation fields include stamps, tumour bed, proximal nodal chains and nodes corresponding to D2 extended lymph nodes dissection. Treatment was feasible with few severe toxic effects (1%). Of the 281 patients, 17% stopped treatment because toxic effects. Technical modalities of radiotherapy and post-operative nutrition support which are critical points of interest for this treatment, are also discussed. (authors)

  18. Effects of pharmaceuticals on immune parameters of aquatic invertebrates

    2014-05-01

    Full Text Available Pharmaceuticals are a large group of chemicals used either by humans for personal health or by agribusiness to enhance the growth and health of livestock. Pharmaceuticals are considered to be emerging environmental contaminants. Indeed, several studies have shown that these compounds continuously enter aquatic ecosystems. Both pharmaceutical consumption and erroneous discharge of unused or expired medications make notable contributions to the introduction of pharmaceuticals into the environment. Additionally, pharmaceuticals consumed by humans and livestock are not entirely absorbed by organisms and are excreted and passed into wastewater and surface water. Although most pharmaceuticals are designed for human consumption, they can affect non-target organisms that share certain homologous receptors with humans. This review intends to summarise the most recent information concerning the effects of some classes of pharmaceuticals on the immune parameters of aquatic invertebrates.

    Full Text Available The concept of the learning organization has gone through many changes both theoretically and also as practical implementation. Learning organizations do not appear automatically, they require a strong commitment for developing the skills needed in the workplace, and this commitment should start from the top of the organization. The learning process should be managed at different levels within the organization. Learning, therefore, is made up of several different components and requires a special management. Successful companies are the result of carefully cultivated attitudes, commitments and management processes. This paper investigates the learning organization dimensions analysed in case of pharmaceutical SMEs from Romania. The results obtained in this study allow us to draw relevant conclusions, constituting a practical starting point for businesses. The paper highlights the fact that SMEs pharmaceutical companies have taken important steps toward learning organization model, but reaching different levels from one key dimension to another.

    This article analyzes the World Bank's lending activity on pharmaceuticals and medical products (PMP) during the fiscal years (FY) 1999-2001 by regions, borrower and supplier country, and procurement method. Data for the study derived from the World Bank Project and the Business Warehouse databases. The information included all Bank projects approved during the study period. Information for the PMP procurement contracts was extracted for the health sector components of all sector projects awarded. Contract dollar amount was aggregated by borrower and supplier countries. A total of 365 contracts of PMP for a value of US$ 364.5 million (2001 prices) were awarded. International competitive bidding was the most common procurement method used representing 46.0% of the total PMP contracts amount. Domestic providers supplied 52.5% of the PMP contracts managed by the borrower countries. Twenty-two countries accounted for 97.0% of the total PMP purchased during the period of analysis. Only a small fraction of the Bank activity was directed to the pharmaceutical sector. There is a need for more involvement of the World Bank to increase accessibility, affordability and rational use of pharmaceuticals and medical products. An evaluation of the different procurement methods and their implications on drug quality and prices should be performed. PMID:16824640

    2010-01-01

    Full Text Available Mexican pharmaceutical market is the most important in Latin America and a significant number of global firms have different business activities in this country: production, licensing of patents, alliances with Mexican firms, distribution facilities or partnerships, etc. In terms of innovation, global pharmaceutical industry has passed through structural changes mainly of technological and institutional nature. These changes have been influential along the whole value chain and have triggered transformations in firm's organization, market structure and sector's investments. Mexico's industry, in spite of having a very attractive domestic market, has serious limitations for technology development. Very little resources are invested in R&D and lack of articulation between research labs and industry provoke that Mexico has only exceptional innovation achievements and a high technological dependence. At the same time, some Mexican companies have developed new strategies to be competitive in open markets and have shown that a combination of competitive intelligence, rapid adoption of technologies, collaboration with advanced firms and research institutes, permanent training and continuous improvement are key factors for success. This paper deals with the results of a piece of research aimed at developing a model for the effective transfer of technology for Mexican pharmaceutical firms, with a strong component of knowledge and skills to manage the flows of information, people and technologies among firms, research labs, universities and other health organizations.

    The term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.e., assuring adequate patient adherence and the anticipate drug safety and effectiveness. Relevant pharmaceutical design aspects may e.g., involve the selection of the route of administration, the tablet size and shape, the ease of opening the package, the ability to read the user instruction, or the ability to follow the recommended (in-use) storage conditions. Currently, a harmonized definition on patient centric drug development/design has not yet been established. To stimulate scientific research and discussions and the consistent interpretation of test results, it is essential that such a definition is established. We have developed a first draft definition through various rounds of discussions within an interdisciplinary AAPS focus group of experts. This publication summarizes the outcomes and is intended to stimulate further discussions with all stakeholders towards a common definition of patient centric pharmaceutical drug product design that is useable across all disciplines involved.

This dualism often results in economic, political and social dilemmas influencing the viability of organisations in general, and more specifically and recently, local and international pharmaceutical organisations operating in South Africa. This article considers the aspect of corporate social responsibility (CSR in general and attempts to identify the social-related issues impacting on the pharmaceutical industry by means of content analysis - a research technique for making replicable and valid inferences from data. It furthermore describes the re-action of pharmaceutical organisations when confronted with such social demands, and finally analyses the management of CSR against four criteria of CSR. The article confirms the importance of managers to manage CSR towards society in a proactive manner. It furthermore suggests that the "hard" factors of strategic management and financial performance should be balanced with "soft" social/people issues. It also recommends that the industry should consider - and if applicable - endorse the concept of Issues Management as an approach to the proactive management of CSR.

    Full Text Available As more and more innovative drug products (e.g., chemical drug and biological drug products are going off patent protection, the development of generics/biosimilars products have become the center of attention of many pharmaceutical companies. In addition, as new drug research and development has reached the bottle-neck, the pharmaceutical industry begin to focus on the search for new or alternative medicines such as traditional Chinese medicine that can treat critical and/or life-threatening diseases. To ensure that there is high probability of success, advanced technology and/or methodology and innovative thinking of trial designs are necessarily applied. The advanced technology/methodology include two-way translational process from bench-to-bedside in translational research, micro-dosing approach for safety evaluation, and big-data analytics for identifying hidden clinical benefits of some test treatments. The innovative thinking of trial designs are referred to adaptive trial designs for identifying optimal clinical benefits of the test treatment under investigation and/or biomarker induced targeted clinical trials for personalized (precision medicine. Along this line, this short commentary provides perspectives of future pharmaceutical development of biosimilar products and traditional Chinese medicine.

    2006-01-01

    In recent years pharmaceutical design has been facing the needs expressed by new therapeutic methodologies such as gene therapy, targeted delivery and closely related diagnostic fields as contrast enhancing agents for ultrasonic investigations. In this context pharmaceutical research has diversified the efforts toward a more integrated approach where the efficacy of an active molecule is enhanced and assisted by the surrounding carrier. Usually this drug platform is a hydrogel matrix, a multicomponent system constituted by an aqueous solution and a polymeric moiety imparting different functions to the matrix, as responsiveness to external stimuli, affinity to receptors, controlled drug release. Such devices represent one of the leading topics of the soft condensed matter recent research, a domain where physics, chemistry and bioengineering cross each other with the aim to achieve an integrated description of these materials. In this respect modern drug design will make use more and more of concepts proper of soft condensed polymer and colloidal sciences. In this review we will describe the state-of-art in the field of the matrices used in innovative drug formulations with a particular emphasis on the implications to pharmaceutical design along with the experimental and theoretical investigation tools worked out in the last decade.

    The appearance of a supercritical state was already observed at the beginning of the 19th century. Nevertheless, the industrial extraction of plant and other natural materials started about twenty years ago with the decaffeination of coffee. Today carbon dioxide is the most common gas for supercritical fluid extraction in food and pharmaceutical industry. Since pure supercritical carbon dioxide is a lipophilic solvent, mixtures with organic solvents, especially alcohols, are used to increase the polarity of the extraction fluid; more polar compounds can be extracted in this way. The main fields of interest are the extraction of vegetable oils from plant material in analytical and preparative scale, the preparation of essential oils for food and cosmetic industry and the isolation of substances of pharmaceutical relevance. Progress in research was made by the precise measurement of phase equilibria data by means of different methods. Apart from extraction, supercritical fluid chromatography was introduced in the field of analytics, as well as micro- and nanoparticle formation using supercritical fluids as solvent or antisolvent. This review presents pharmaceutical relevant literature of the last twenty years with special emphasis on extraction of natural materials.

    The term "patient centered," "patient centric," or "patient centricity" is increasingly used in the scientific literature in a wide variety of contexts. Generally, patient centric medicines are recognized as an essential contributor to healthy aging and the overall patient's quality of life and life expectancy. Besides the selection of the appropriate type of drug substance and strength for a particular indication in a particular patient, due attention must be paid that the pharmaceutical drug product design is also adequately addressing the particular patient's needs, i.e., assuring adequate patient adherence and the anticipate drug safety and effectiveness. Relevant pharmaceutical design aspects may e.g., involve the selection of the route of administration, the tablet size and shape, the ease of opening the package, the ability to read the user instruction, or the ability to follow the recommended (in-use) storage conditions. Currently, a harmonized definition on patient centric drug development/design has not yet been established. To stimulate scientific research and discussions and the consistent interpretation of test results, it is essential that such a definition is established. We have developed a first draft definition through various rounds of discussions within an interdisciplinary AAPS focus group of experts. This publication summarizes the outcomes and is intended to stimulate further discussions with all stakeholders towards a common definition of patient centric pharmaceutical drug product design that is useable across all disciplines involved.

    Graphene-based nanosheets (GNS) are atomic-thickness monolayers of hexagonally arranged, graphite-derived carbon atoms that may be composed of graphene, graphene oxide, or reduced graphene oxide. They have attracted tremendous interest for their potential in pharmaceutical applications, due to their unique physical, chemical, and mechanical properties GNS exhibit highly uniform surface areas and may have hydroxyl (-OH), epoxide (-O-), and carboxyl functional groups at their basal surfaces and plane edges, depending on their oxidized and reduced surface properties. GNS show high-level optical absorption of near infrared (NIR) light and elevate the temperature of nearby environments. Furthermore, they can be loaded with anticancer drugs via hydrophobic interactions, π-π stacking, or electrostatic binding. Given these properties, GNS can be used in chemotherapy, photodynamic therapy, photothermal therapy, and theranostics. However, although GNS appear to have far-reaching potential in the field of biomedical research, their widespread pharmaceutical application has been limited by issues such as poor stability in physiological buffers, undefined mechanisms of cellular uptake, toxicity problems, and a lack of standard preparation methods. Here, we review the current pharmaceutical applications of GNS, focusing on chemotherapy, phototherapy, combo therapy and theranostic applications with challenging issues.

    Full Text Available Due to various advantages such as high-precision dosing, manufacturing efficiency and patient compliance helped making tablets the most popular dosage forms among all available dosages forms. Compaction, which is an essential manufacturing step in the manufacture of tablets, mainly includes compression (i.e. reduction of volume of the powder under consideration and particle rearrangement and consolidation (i.e., formation of interparticulate bond to facilitate stable compaction. The success of the compaction process depends not only on the physico-technical properties of drugs and excipients, but also on the instrument settings with respect to rate and magnitude of force transfer. Tablet manufacturing speed and pre/main compression force profile also have an influence on the quality of the final tablet. Mechanical aspects of tablet formation can be studied using, instrumented punches/dies, instrumented tablet punching machines, and compaction simulators. These have potential application in pharmaceutical research and development, such as studying basic compaction mechanism, various process variables, scale-up parameters, trouble shooting problems, creating compaction data library, and fingerprinting of new active pharmaceutical ingredients (APIs or excipients. Mathematical models, force-time, force-distance, and die-wall force parameters of tablet manufacturing are used to describe work of compaction, elasticity/plasticity, and time dependent deformation behavior of pharmaceuticals powder under consideration.

    Full Text Available Breast cancer is the most frequent neoplasm affecting women worldwide. Some of the recommended treatments involve chemotherapy whose toxic effects include leukopenia and neutropenia. This study assessed the effectiveness of Uncaria tomentosa (Ut in reducing the adverse effects of chemotherapy through a randomized clinical trial. Patients with Invasive Ductal Carcinoma—Stage II, who underwent a treatment regimen known as FAC (Fluorouracil, Doxorubicin, Cyclophosphamide, were divided into two groups: the UtCa received chemotherapy plus 300 mg dry Ut extract per day and the Ca group that only received chemotherapy and served as the control experiment. Blood samples were collected before each one of the six chemotherapy cycles and blood counts, immunological parameters, antioxidant enzymes, and oxidative stress were analyzed. Uncaria tomentosa reduced the neutropenia caused by chemotherapy and was also able to restore cellular DNA damage. We concluded that Ut is an effective adjuvant treatment for breast cancer.

    Breast cancer in the elderly is an increasing clinical problem. In addition, ~60% of deaths from breast cancer occur in women aged 65 years and older. Despite this, older women with breast cancer have been underrepresented in clinical trials, and this has led to less than optimal evidence to guide their therapy. The management of elderly women with early breast cancer is a complex process that requires careful evaluation of life expectancy, comorbidities, patient values, and risks and benefits of available treatment options. This review will focus on current adjuvant systemic therapy options for older women with breast cancer, discuss the principles in the decision-making process, and define the role of endocrine therapy, chemotherapy, and targeted agents.

    We have synthesized thermogelling cationic amphiphilic pentablock copolymers that have the potential to act as injectable vaccine carriers and adjuvants that can simultaneously provide sustained delivery and enhance the immunogenicity of released antigen. While these pentablock copolymers have shown efficacy in DNA delivery in past studies, the ability to deliver both DNA and protein for subunit vaccines using the same polymeric carrier can provide greater flexibility and efficacy. We demonstrate the ability of these pentablock copolymers, and the parent triblock Pluronic copolymers to slowly release structurally intact and antigenically stable protein antigens in vitro, create an antigen depot through long-term injection-site persistence and enhance the in vivo immune response to these antigens. We show release of the model protein antigen ovalbumin in vitro from the thermogelling block copolymers with the primary, secondary and tertiary structures of the released protein unchanged compared to the native protein, and its antigenicity preserved upon release. The block copolymers form a gel at physiological temperatures that serves as an antigenic depot and persists in vivo at the site of injection for over 50days. The pentablock copolymers show a significant fivefold enhancement in the immune response compared to soluble protein alone, even 6weeks after the administration, based on measurement of antibody titers. These results demonstrate the potential of these block copolymers hydrogels to persist for several weeks and sustain the release of antigen with minimal effects on protein stability and antigenicity; and their ability to be used simultaneously as a sustained delivery device as well as a subunit vaccine adjuvant platform.

    Full Text Available Aluminum oxyhydroxide (alum is a crystaline compound widely used as an immunologic adjuvant of vaccines. Concerns linked to the use of alum particles emerged following recognition of their causative role in the so-called macrophagic myofasciitis (MMF lesion detected in patients with myalgic encephalomyelitis/chronic fatigue/syndrome. MMF revealed an unexpectedly long-lasting biopersistence of alum within immune cells in presumably susceptible individuals, stressing the previous fundamental misconception of its biodisposition. We previously showed that poorly biodegradable aluminum-coated particles injected into muscle are promptly phagocytozed in muscle and the draining lymph nodes, and can disseminate within phagocytic cells throughout the body and slowly accumulate in brain. This strongly suggests that long-term adjuvant biopersistence within phagocytic cells is a prerequisite for slow brain translocation and delayed neurotoxicity. The understanding of basic mechanisms of particle biopersistence and brain translocation represents a major health challenge, since it could help to define susceptibility factors to develop chronic neurotoxic damage. Biopersistence of alum may be linked to its lysosome-destabilizing effect, which is likely due to direct crystal-induced rupture of phagolysosomal membranes. Macrophages that continuously perceive foreign particles in their cytosol will likely reiterate, with variable interindividual efficiency, a dedicated form of autophagy (xenophagy until they dispose of alien materials. Successful compartmentalization of particles within double membrane autophagosomes and subsequent fusion with repaired and re-acidified lysosomes will expose alum to lysosomal acidic pH, the sole factor that can solubilize alum particles. Brain translocation of alum particles is linked to a Trojan horse mechanism previously described for infectious particles (HIV, HCV, that obeys to CCL2 signaling the major inflammatory monocyte

The pharmaceutical business also searched for their share in the delivery of military supplies and the distribution of relief supplies. The supply-side pharmaceutical policy made the pharmaceutical market a wholesale business. The gravity of the situation led to an increased importation of medical supplies, and wholesalers took the lead in establishing the distribution structure, whereas consumers and pharmaceutical business were relatively intimidated. The aid provided by the International Cooperation Administration (ICA) marked a turning point in the Korean pharmaceutical industry after the middle of the 1950s.

    The aim of this study was to explore the effect of Cornus officinalis glucosides (COG) on adjuvant-induced arthritis in rats and its mechanism. Seventy-two rats were divided into six groups of normal, model, Dexasone (0. 125 mg/kg), high-dose COG (240 mg/kg), mid-dose COG (120 mg/kg),and low-dose COG (60 mg/kg). Rat arthritis was induced by injection of Freund's complete adjuvant in the hind paws. All treatment started from the day the arthritis was induced. The edema degree of the adjuvant injection location was determined on days 1, 3, 5, 7, 9, 11, 13, 15, 17, 20, 23 and the opposite side was observed on days 11, 13, 15, 17, 20, 23 after the injection of adjuvant. All rats were sacrificed on day 24 after the injection of adjuvant for microscopic examination of the ankle, and for the study of the immunological molecular mechanism. The results showed that the COG significantly suppressed both the primary and secondary edema, improved pathological injuries of adjuvant arthritis (AA)rat ankles, significantly suppressed the proliferation of T lymphocytes and DTH reaction. It significantly suppressed IL-1, IL-6 and TNF-α production from peritoneal macrophages and PGE2 in plasma. In conclusion, the Cornus officinalis glucosides (COG) is able to prevent and cure the rat adjuvant-induced arthritis, and can suppress the production of pro-inflammatory cytokine IL-1, IL-6, TNF-α and PGE2.

    Full Text Available Vaccine efficacy is optimized by addition of immune adjuvants. However, although adjuvants have been used for over a century, to date, only few adjuvants are approved for human use, mostly aimed at improving vaccine efficacy and antigen-specific protective antibody production. The mechanism of action of immune adjuvants is diverse, depending on their chemical and molecular nature, ranging from non-specific effects (i.e., antigen depot at the immunization site to specific activation of immune cells leading to improved host innate and adaptive responses. Although the detailed molecular mechanism of action of many adjuvants is still elusive, the discovery of Toll-like receptors (TLRs has provided new critical information on immunostimulatory effect of numerous bacterial components that engage TLRs. These ligands have been shown to improve both the quality and the quantity of host adaptive immune responses when used in vaccine formulations targeted to infectious diseases and cancer that require both humoral and cell-mediated immunity. The potential of such TLR adjuvants in improving the design and the outcomes of several vaccines is continuously evolving, as new agonists are discovered and tested in experimental and clinical models of vaccination. In this review, a summary of the recent progress in development of TLR adjuvants is presented.

    The cervical cancer is one of the most common malignancies. Worldwide 500,000 women a year become ill from cervical cancer. The aim of the study was to establish the role of adjuvant radiotherapy in patients with IB1 cervical cancer in terms of disease free survival. Between 2002-2012, 132 patients diagnosed as IB1 stage according to FIGO criteria were enrolled in the study. Depending on the administered therapy the patients were divided into two groups--Group 1-93 patients were treated surgically and with adjuvant radiotherapy and Group 2--39 patients were treated surgically without adjuvant radiotherapy Surgery was radical hysterectomy class III and pelvic or paraaortic lymph node dissection(in cases of bulky paraaortic nodes), and adjuvant RT-telegamma therapy(TGT) in dose 52 Gy. The frequency of recurrence in a Group I (surgery and TGT) is 9.7%. Tree and five years disease free survival (DFS) is 88%. The frequency of recurrence in a Group 2 (surgery without TGT) is 25.6%. Tree and five years DFS respectively are 70% and 65%. In an analysis of oncological results establish that adjuvant TGT after surgery significantly increases DFS. On the other hand the addition of adjuvant TGT increases the patients morbidity Therefore should determine which are the risk factors for the occurrence of relapses and select group of patients who would benefit from adjuvant TGT and the risk of complications in them would be justified.

    When planning pharmaceutical packaging, the package size for the product is important for determining the basic package concept. Initially, the sales unit for herbal medicines was the weight; however in 1868, around the early part of the Meiji era, Japanese and Western units were being used and the sales unit was confusing. Since the Edo era, the packing size for OTC medicines was adopted using weight, numbers, dosage or treatment period. These were devised in various ways in consideration of convenience for the consumer, but the concept was not simple. In 1887, from the time that the first edition of the Japanese Pharmacopoeia came out, use of the metric system began to spread in Japan. Its use spread gradually for use in the package size of pharmaceutical products. At the time, the number of pharmaceutical units (i.e., tablets), became the sales unit, which is easy to understand by the purchaser. PMID:25799840

    As the demand for new drugs is rising, the pharmaceutical industry faces the quest of shortening development time, and thus, reducing the time to market. Environmental aspects typically still play a minor role within the early phase of process development. Nevertheless, it is highly promising to rethink, redesign, and optimize process strategies as early as possible in active pharmaceutical ingredient (API) process development, rather than later at the stage of already established processes. The study presented herein deals with a holistic life-cycle-based process optimization and intensification of a pharmaceutical production process targeting a low-volume, high-value API. Striving for process intensification by transfer from batch to continuous processing, as well as an alternative catalytic system, different process options are evaluated with regard to their environmental impact to identify bottlenecks and improvement potentials for further process development activities.

    The application of confocal laser scanning microscopy (CLSM) to the physicochemical characterisation of pharmaceutical systems is not as widespread as its application within the field of cell biology. However, methods have been developed to exploit the imaging capabilities of CLSM to study a wide range of pharmaceutical systems, including phase-separated polymers, colloidal systems, microspheres, pellets, tablets, film coatings, hydrophilic matrices, and chromatographic stationary phases. Additionally, methods to measure diffusion in gels, bioadhesives, and for monitoring microenvironmental pH change within dosage forms have been utilised. CLSM has also been used in the study of the physical interaction of dosage forms with biological barriers such as the eye, skin and intestinal epithelia, and in particular, to determine the effectiveness of a plethora of pharmaceutical systems to deliver drugs through these barriers. In the future, there is continuing scope for wider exploitation of existing techniques, and continuing advancements in instrumentation.

  8. Application of radio-detoxified endotoxin as adjuvant for experimental foot-and-mouth disease vaccine

    International Nuclear Information System (INIS)

    The immunity enhancing adjuvant activity of radiodetoxified endotoxin (RD-LPS) on the potency of 'C' type foot-and-mouth (FMD) vaccine was tested in different animal species. For radiodetoxification 5 Mrad gamma radiation was used. The suitable quantity of RD-LSP (20 μg per mouse) adjuvated FMD vaccines of lower antigen content better than those of higher one. In cattle and sheep the adjuvant effect of oil + RD + LPS surpassed only slightly that of oil alone. The effect of RD-LPS in pig was very pronounced when applied in small doses but further studies in larger animal populations have to confirm this result. (author)

    AIM: To evaluate the efficacy and toxicity of postoperative chemoradiation using FP chemotherapy and oral capecitabine during radiation for advanced gastric cancer following curative resection.METHODS: Thirty-one patients who had underwent a potentially curative resection for Stage Ⅲ and Ⅳ (MO) gastric cancer were enrolled. Therapy consists of one cycle of FP (continuous infusion of 5-FU 1000 mg/m2 on d 1 to 5 and cisplatin 60 mg/m2 on d 1) followed by 4500 cGy (180 cGy/d) with capecitabine (1650 mg/m2 daily throughout radiotherapy). Four wk after completion of the radiotherapy, patients received three additional cycles of FP every three wk. The median follow-up duration was 22.2 mo.RESULTS: The 3-year disease free and overall survival in this study were 82.7% and 83.4%, respectively. Four patients (12.9%) showed relapse during follow-up. Eight patients did not complete all planned adjuvant therapy.Grade 3/4 toxicities included neutropenia in 50.2%, anemia in 12.9%, thrombocytopenia in 3.2% and nausea/vomiting in 3.2%. Neither grade 3/4 hand foot syndrome nor treatment related febrile neutropenia or death were observed.CONCLUSION: These preliminary results suggest that this postoperative adjuvant chemoradiation regimen of FP before and after capecitabine and concurrent radiotherapy appears well tolerated and offers a comparable toxicity profile to the chemoradiation regimen utilized in INT-0116. This treatment modality allowed successful loco-regional control rate and 3-year overall survival.

    Adjuvants play a key role in boosting immunogenicity of vaccines, particularly for subunit protein vaccines. In this study we investigated the induction of antibody response against trivalent influenza subunit protein antigen and a saponin adjuvant, QS-21. Clinical trials of QS-21 have demonstrated the safety but, also a need of high dose for optimal immunity, which could possibly reduce patient acceptability. Here, we proposed the use of a skin delivery technology - the Nanopatch - to reduce both adjuvant and antigen dose but also retain its immune stimulating effects when compared to the conventional needle and syringe intramuscular (IM) delivery. We have demonstrated that Nanopatch delivery to skin requires only 1/100(th) of the IM antigen dose to induce equivalent humoral response. QS-21 enhanced humoral response in both skin and muscle route. Additionally, Nanopatch has demonstrated 30-fold adjuvant QS-21 dose sparing while retaining immune stimulating effects compared to IM. QS-21 induced localised, controlled cell death in the skin, suggesting that the danger signals released from dead cells contributed to the enhanced immunogenicity. Taken together, these findings demonstrated the suitability of reduced dose of QS-21 and the antigen using the Nanopatch to enhance humoral responses, and the potential to increase patient acceptability of QS-21 adjuvant.

  11. Coordinated research project on radiation sterilization and decontamination of pharmaceuticals and pharmaceutical raw materials. CRP report

    International Nuclear Information System (INIS)

    Radiation processing is a very convenient tool for imparting desirable effects in materials and it has been an area of enormous interest in the last few decades. Radiation processing of synthetic and natural polymers for improving their characteristics is largely used in laboratory and industrial scale. Radiation sterilization is a well developed and established technology for many products. It is especially useful for the treatment of pharmaceuticals due to flexibility of radiation processing to be carried out at any desired temperature, sterilizability of mixed products in kits, offering simultaneous sterilization and modification of polymer based formulations. The success of radiation technology for processing of synthetic and natural polymers and treatment of pharmaceuticals has been based, to a large extent, on empirical knowledge. But now, the applications of natural polymers are being sought in knowledge-demanding areas such as pharmacy and biotechnology. Reliable analytical methods are being developed for controlling of degradation effects of radiation on polymers. Procedures and chemical formulations are being investigated enhancing or preventing degradation effects depending on the desired application of the process. The Coordinated Research Project (CRP) on the use of radiation processing for sterilization or decontamination of pharmaceuticals and pharmaceutical raw materials has been completed in 2002. The overall objective of the CRP was to coordinate the research and development programmes carried out in different countries in use of radiation processing for sterilization or decontamination of pharmaceuticals and pharmaceutic raw materials. It has been concluded that in addition to well known advantages of radiation sterilization being a well developed and established technology requiring the control of only one parameter, dose, to achieve sterilization; it is especially useful for the treatment of pharmaceuticals due to flexibility of radiation

    Despite recent changes in attitudes, most hospitals continue to experience pharmaceutical industry presence. Pharmaceutical industry presence may be necessary and beneficial in the context of sponsorship of clinical trials with appropriate governance. Doctors continue to hold positive attitudes towards market-oriented activities of the pharmaceutical and medical device industries. Despite evidence to the contrary, doctors believe they are able to effectively manage pharmaceutical sales representative interactions such that their own prescribing is not adversely impacted. Doctors also share a belief that small gifts and benefits are harmless. There may be significant financial burden associated with divestment of such sponsorship by hospitals. Change requires education and effective policies to manage pharmaceutical industry relationships and conflicts of interest. We discuss case studies involving students and public hospital doctors to show that divestment is possible without significant financial detriment. Health services need to be proactive in transitioning financial and cultural reliance on pharmaceutical industry sponsorship to other potentially less harmful sources. PMID:26763810

    The effect of macro-, middle- and microeconomic factors on price formation in Azerbaijan pharmaceutical market has been studied. Worldwide pharmaceutical leaders have the goals to become leader on the pharmaceutical market of Azerbaijan and maximize their market share. Non-leaders pharmaceutical companies use different strategies of price formation: prime cost plus markup, or price formation on the base of current prices. It was revealed that domestic pharmaceutical market has high demand elasticity. Future market development is related to stimulation of product development, and hard penetration to the market through realization of price formation strategy. Non-state pharmaceutical organizations to achieve the purpose of survive in conditions of high competition should take in to account the factor perceptions of assortment by customers.

    Anthropologists of medicine and science are increasingly studying all aspects of pharmaceutical industry practices--from research and development to the marketing of prescription drugs. This article ethnographically explores one particular stage in the life cycle of pharmaceuticals: sales and marketing. Drawing on a range of sources-investigative journalism, medical ethics, and autoethnography--the author examines the day-to-day activities of pharmaceutical salespersons, or drug reps, during the 1990s. He describes in detail the pharmaceutical gift cycle, a three-way exchange network between doctors, salespersons, and patients and how this process of exchange is currently in a state of involution. This gift economy exists to generate prescriptions (scripts) and can mask and/or perpetuate risks and side effects for patients. With implications of pharmaceutical industry practices impacting everything from the personal-psychological to the global political economy, medical anthropologists can play a lead role in the emerging scholarly discourse concerned with critical pharmaceutical studies.

    Belal, Tarek Saied

    2008-09-01

    A simple, rapid, selective and sensitive spectrofluorimetric method was described for the analysis of three nitrofuran drugs, namely, nifuroxazide (NX), nitrofurantoin (NT) and nitrofurazone (NZ). The method involved the alkaline hydrolysis of the studied drugs by warming with 0.1 M sodium hydroxide solution then dilution with distilled water for NX or 2-propanol for NT and NZ. The formed fluorophores were measured at 465 nm (lambda (Ex) 265 nm), 458 nm (lambda (Ex) 245 nm) and 445 nm (lambda (Ex) 245 nm) for NX, NT and NZ, respectively. The reaction pathway was discussed and the structures of the fluorescent products were proposed. The different experimental parameters were studied and optimized. Regression analysis showed good correlation between fluorescence intensity and concentration over the ranges 0.08-1.00, 0.02-0.24 and 0.004-0.050 microg ml(-1) for NX, NT and NZ, respectively. The limits of detection of the method were 8.0, 1.9 and 0.3 ng ml(-1) for NX, NT and NZ, respectively. The proposed method was validated in terms of accuracy, precision and specificity, and it was successfully applied for the assay of the three nitrofurans in their different dosage forms. No interference was observed from common pharmaceutical adjuvants. The results were favorably compared with those obtained by reference spectrophotometric methods. PMID:18246413

    2016-02-01

    Cyclodextrins are cyclic oligosaccharides that have been recognized as pharmaceutical adjuvants for the past 20 years. The molecular structure of these glucose derivatives, which approximates a truncated cone, bucket, or torus, generates a hydrophilic exterior surface and a nonpolar interior cavity. Cyclodextrins can interact with appropriately sized drug molecules to yield an inclusion complex. These noncovalent inclusion complexes offer a variety of advantages over noncomplexed forms of a drug. Cyclodextrins are carbohydrates that are primarily used to enhance the aqueous solubility, physical chemical stability, and bioavailability of drugs. Their other applications include preventing drug-drug interactions, converting liquid drugs into microcrystalline powders, minimizing gastrointestinal and ocular irritation, and reducing or eliminating unpleasant taste and smell. Here, we focus on the solubilization of drugs by complexation, and discuss the determination and significance of binding constants for cyclodextrin complexes, and the determination of complexation efficiency and factors that influence it. We also make some general observations on cyclodextrin complexation and the use of cyclodextrins in solid, as well as parenteral, dosage forms. PMID:26687191

  20. Academic psychiatry and the pharmaceutical industry.

    Ban, Thomas A

    2006-05-01

    In the second half of the 19th century new drugs introduced by the pharmaceutical industry helped lead to the establishment of academic departments in psychiatry. Causal treatment of cerebral pellagra by nicotinic acid and cerebral syphilis by penicillin in the first half of the 20th century led to major changes in the diagnostic distribution of psychiatric patients. In the second half of the 20th century with the introduction of a rapidly growing number of psychotropic drugs, pharmacotherapy became the primary form of treatment in mental illness. Psychiatrists today perceive neuropharmacology as one of the basic sciences of psychiatry and psychopharmacology as the bridge between the mode of action and the clinical indications of psychotropic drugs. Pharmacotherapy with psychotropic drugs focused attention on the differential responsiveness to the same drug within the same diagnostic category. Yet, instead of re-evaluating psychiatric nosology and conducting research in psychopathology, a statistical methodology was adopted for the demonstration of therapeutic effectiveness in pharmacologically heterogeneous populations. Employment of consensus-based classifications and psychiatric rating scales in the clinical development of psychotropic drugs led to semi-finished products, which are prescribed indiscriminately. Replacement of single-center clinical trials by multi-center centrally coordinated clinical investigations led to the control of education in pharmacotherapy by the pharmaceutical industry. To separate education from marketing, the identification of the treatment-responsive forms of illness and the delineation of the therapeutic profile of psychotropic drugs are proposed with the employment of a new methodology, the "Composite Diagnostic Evaluation System." It is postulated that development of a pharmacologically valid psychiatric nosology with the employment of a "nosologic matrix" would provide the pharmaceutical industry with the necessary feedback to

    Simple, rapid and highly sensitive spectrofluorimetric method is presented for the determination of four fluoroquinolone (FQ) drugs, ciprofloxacin, enoxacin, norfloxacin and moxifloxacin in pharmaceutical preparations. Proposed method is based on the derivatization of FQ with 4-chloro-7-nitrobenzofurazan (NBD-Cl) in borate buffer of pH 9.0 to yield a yellow product. The optimum experimental conditions have been studied carefully. Beer's law is obeyed over the concentration range of 23.5-500 ng mL -1 for ciprofloxacin, 28.5-700 ng mL -1 for enoxacin, 29.5-800 ng mL -1 for norfloxacin and 33.5-1000 ng mL -1 for moxifloxacin using NBD-Cl reagent, respectively. The detection limits were found to be 7.0 ng mL -1 for ciprofloxacin, 8.5 ng mL -1 for enoxacin, 9.2 ng mL -1 for norfloxacin and 9.98 ng mL -1 for moxifloxacin, respectively. Intra-day and inter-day relative standard deviation and relative mean error values at three different concentrations were determined. The low relative standard deviation values indicate good precision and high recovery values indicate accuracy of the proposed methods. The method is highly sensitive and specific. The results obtained are in good agreement with those obtained by the official and reference method. The results presented in this report show that the applied spectrofluorimetric method is acceptable for the determination of the four FQ in the pharmaceutical preparations. Common excipients used as additives in pharmaceutical preparations do not interfere with the proposed method.

    Seventy years ago, the Curtin wartime government introduced legislation for a Pharmaceutical Benefits Scheme (PBS). It was a response to the need to provide access to a wave of antibiotic drugs - sulfonamides, streptomycin, penicillin - to the whole population, not only to the minority able to afford them. The scheme was immediately and successfully opposed by doctors and the conservative opposition, which saw in universal health care an underhand plan to nationalise medicine. There were two High Court challenges, two referendums and a constitutional amendment; but it was not until 1960 that Australians had the comprehensive PBS envisaged by Curtin in 1944. PMID:25047771

    The applied use of in silico technologies (a.k.a. computational toxicology, in silico toxicology, computer-assisted tox, e-tox, i-drug discovery, predictive ADME, etc.) for predicting preclinical toxicological endpoints, clinical adverse effects, and metabolism of pharmaceutical substances has become of high interest to the scientific community and the public. The increased accessibility of these technologies for scientists and recent regulations permitting their use for chemical risk assessment supports this notion. The scientific community is interested in the appropriate use of such technologies as a tool to enhance product development and safety of pharmaceuticals and other xenobiotics, while ensuring the reliability and accuracy of in silico approaches for the toxicological and pharmacological sciences. For pharmaceutical substances, this means active and impurity chemicals in the drug product may be screened using specialized software and databases designed to cover these substances through a chemical structure-based screening process and algorithm specific to a given software program. A major goal for use of these software programs is to enable industry scientists not only to enhance the discovery process but also to ensure the judicious use of in silico tools to support risk assessments of drug-induced toxicities and in safety evaluations. However, a great amount of applied research is still needed, and there are many limitations with these approaches which are described in this review. Currently, there is a wide range of endpoints available from predictive quantitative structure-activity relationship models driven by many different computational software programs and data sources, and this is only expected to grow. For example, there are models based on non-proprietary and/or proprietary information specific to assessing potential rodent carcinogenicity, in silico screens for ICH genetic toxicity assays, reproductive and developmental toxicity, theoretical

    2013-01-01

    Full Text Available Five simple, accurate, and sensitive spectrophotometric methods (A–E have been described for the indirect assay of pipazethate HCl (PZT either in pure form or in pharmaceutical preparations. The proposed methods are based on the bromination of pipazethate HCl with a solution of excess bromate-bromide mixture in hydrochloric acid medium and subsequent estimation of the residual bromine by different reaction schemes. In the first three methods (A–C, the determination of the residual bromine is based on its ability to bleach the color of methyl orange, indigo carmine, or thymol blue dyes and measuring the absorbance at 520, 610, and 550 nm for methods A, B, and C, respectively. Methods D and E involves treating the unreacted bromine with a measured excess of iron(II, and the remaining iron(II is complexed with 1,10-phenanthroline, and the increase in absorbance is measured at 510 nm for method D and the resulting iron(III is complexed with thiocyanate and the absorbance is measured at 480 nm for method E. The different experimental parameters affecting the development and stability of the color are carefully studied and optimized. Regression analysis of the Beer-Lambert plots showed good correlation in the concentration ranges of 0.5–8.0 μg . The apparent molar absorptivity, Sandell's sensitivity, detection and quantitation limits were evaluated. The proposed methods have been applied and validated successfully for the analysis of the drug in its pure form and pharmaceutical formulations with mean recoveries of 99.94%–100.15% and relative standard deviation ≤1.53. No interference was observed from a common pharmaceutical adjuvant. Statistical comparison of the results with the reference method shows excellent agreement and indicates no significant difference in accuracy and precision.

Essa neoplasia ocorre devido à mutação do gene KIT com consequente ativação constitutiva da proteína KIT. O tratamento primário é cirúrgico e consiste na sua ressecção completa. Entretanto, alguns grupos de pacientes apresentam risco elevado de recorrência mesmo após operação com ressecção completa (R0, indicando diferenças no comportamento biológico. Estudos clínicos comprovaram a atividade clínica do mesilato de imatinibe, fazendo dele a primeira linha de tratamento padrão nos GISTs metastáticos ou irressecáveis, mudando muito o desfecho clínico dessa doença em relação aos benefícios anteriormente obtidos com a quimioterapia antineoplásica. MÉTODO: Foi realizada revisão da literatura com consulta nos periódicos das bases Medline/Pubmed, Scielo e Lilacs cruzando os descritores: tumor estromal gastrointestinal, Gist, tratamento, adjuvância. Além desta revisão foi adicionada a experiência pessoal dos autores. CONCLUSÃO: Melhor refinamento dos critérios de prognóstico tem permitido selecionar de forma mais adequada pacientes para o tratamento adjuvante com imatinibe. Os resultados de maior evidência até o momento respaldam o tratamento adjuvante por um ano, o que produz benefício significativo na sobrevida livre de recidiva, mas não na sobrevida global desses pacientes.INTRODUCTION: Gastrointestinal stromal tumor (GIST is the most common sarcoma of the digestive tract.

  10. Adjuvant whole abdominal radiotherapy in epithelial cancer of the ovary

    International Nuclear Information System (INIS)

    Purpose: To reexamine the use of adjuvant radiotherapy in optimally debulked patients. Methods and Materials: Between January 1985 and April 1998, 60 patients were treated with adjuvant whole abdominal radiotherapy (A-WART). The stage distribution was Stage IC in 17 patients, Stage II in 9, and Stage III in 34. The grade distribution was Grade 1 in 9 patients, Grade 2 in 27, and Grade 3 in 24; thus, 60% of the patients had Stage III disease and 40% had Grade 3 tumors. After surgery, no residuum was left in 42 (70%), ≤2 cm in 13 (22%), and >2 cm in 5 (8%) of 60 patients. Of the 60 patients, 19 also received platinum-based chemotherapy; in 12 of the 19, the chemotherapy was before A-WART. Thirty-seven of the patients had undergone previous abdominal procedures and a second-look operation was performed in 25% of them. A-WART consisted of 22 Gy in 22 fractions, at 5 fractions weekly in 90% of the patients. The remaining 10% received 25 Gy in 25 fractions within 5 weeks. The A-WART was delivered using a 4-MV linear accelerator. After abdominal irradiation, a boost to the pelvis was given to reach 45 Gy at 1.8 cGy/fraction, using a 4-15-MV linear accelerator. Results: Treatment was delivered in a median of 50 days (range 48-70). In 12 (20%) of the 60 patients, a transient treatment interruption occurred because of acute toxicity, mainly vomiting and diarrhea. The overall survival rate was 55% at 5 years (median follow-up 96.5 months). Patients with low-histologic grade tumors (Grade 1-2) had a better 5-year survival rate (66%) than those with Grade 3 tumors (35%; p<0.03). A tendency for better survival was found for those with Stage I-II than for those with Stage III (69% vs. 43%). Nonetheless, this difference did not reach statistical significance (p 0.17). For patients receiving chemotherapy, the 5-year survival rate was 51%, not statistically different from the 58% 5-year survival rate observed among those patients without adjuvant chemotherapy (p=0.9).

    Pharmaceutical is one of the allied branches of science, which is closely associated with Medical science. Today pharmaceutical chemistry and pharmacognosy are playing important role in treatment for a disease and its prevention. Herbal medicines are being used by about 80% of the world population mostly in the developing countries in the primary health care. There has been an upsurge in demand for the Phyto-pharmaceutical products of Ayurvĕda in western nations, because of the fact that the synthetic drugs are considered to be unsafe. Due to this many national and multinational pharmaceutical companies are now concentrating on manufacturing of Ayurvĕdic Phyto-pharmaceutical products. Ayurvĕda is the Indian traditional system of medicine, which also deals about pharmaceutical science. The Ayurvĕdic knowledge of the pharmaceutical science is scattered in Ayurvĕdic classical texts. Săranghadhara Samhita, which is written by Săranghadhara, explain systematically about the information of the Ayurvĕdic pharmaceutical science and also updated it. Industrialized manufacturing of Ayurvĕdic dosage forms has brought in new challenges like deviation from basic concepts of medicine preparation. Săranghadhara Samrhită the devout text on pharmaceutics in Ayurvĕda comes handy to solve such problems, as the methods described are very lucid and easy to follow. PMID:17333665

    The NASA Human Research Program (HRP) Health Countermeasures Element maintains ongoing efforts to inform detailed risks, gaps, and further questions associated with the use of pharmaceuticals in space. Most recently, the Pharmacology Risk Report, released in 2010, illustrates the problems associated with maintaining pharmaceutical efficacy. Since the report, one key publication includes evaluation of pharmaceutical products stored on the International Space Station (ISS). This study shows that selected pharmaceuticals on ISS have a shorter shelf-life in space than corresponding terrestrial controls. The HRP Human Research Roadmap for planetary exploration identifies the risk of ineffective or toxic medications due to long-term storage during missions to Mars. The roadmap also identifies the need to understand and predict how pharmaceuticals will behave when exposed to radiation for long durations. Terrestrial studies of returned samples offer a start for predictive modeling. This paper shows that pharmaceuticals returned to Earth for post-flight analyses are amenable to a Weibull distribution analysis in order to support probabilistic risk assessment modeling. The paper also considers the prospect of passive payloads of key pharmaceuticals on sample return missions outside of Earth's magnetic field to gather additional statistics. Ongoing work in radiation chemistry suggests possible mitigation strategies where future work could be done at cryogenic temperatures to explore methods for preserving the strength of pharmaceuticals in the space radiation environment, perhaps one day leading to an architecture where pharmaceuticals are cached on the Martian surface and preserved cryogenically.

    In modern medicine pharmaceuticals play a decisive role: because of an increased life expectancy and intensive care medicine an increasing amount of pharmaceuticals is produced. thus these substances are consumed in a mass of tons per year in industrialized countries. Wastewater effluents from sewage treatment plants (STP) are important point sources for residues of pharmaceuticals and complexing agents in the aquatic environment. For this reason a research project, which started in December 2006, was established to eliminate pharmaceutical substances and complexing agents found in wastewater as micropollutants. (Author)

    The measurement uncertainty provides complete information about an analytical result. This is very important because several decisions of compliance or non-compliance are based on analytical results in pharmaceutical industries. The aim of this work was to evaluate and discuss the estimation of uncertainty in pharmaceutical analysis. The uncertainty is a useful tool in the assessment of compliance or non-compliance of in-process and final pharmaceutical products as well as in the assessment of pharmaceutical equivalence and stability study of drug products.

    Full Text Available Studies of active drug/excipient compatibility represent an important phase in the preformulation stage of the development of all dosage forms. The potential physical and chemical interactions between drugs and excipients can affect the chemical nature, the stability and bioavailability of drugs and, consequently, their therapeutic efficacy and safety. The present review covers the literaturereports of interaction and incompatibilities of commonly used pharmaceutical excipients with different active pharmaceutical ingredients in solid dosage forms. Examples of active drug/excipientinteractions, such as transacylation, the Maillard browning reaction, acid base reactions and physical changes are discussed for different active pharmaceutical ingredients belonging to different therapeuticcategories viz antiviral, anti-inflammatory, antidiabetic, antihypertensive, anti-convulsant, antibiotic,bronchodialator, antimalarial, antiemetic, antiamoebic, antipsychotic, antidepressant, anticancer, anticoagulant and sedative/hypnotic drugs and vitamins. Once the solid-state reactions of a pharmaceutical system are understood, the necessary steps can be taken to avoid reactivity and improve the stability of drug substances and products.

    There is an urgent need for a new and improved vaccine against tuberculosis for controlling this disease that continues to pose a global health threat. The current research strategy is to replace the present BCG vaccine or boost BCG-immunity with subunit vaccines such as viral vectored- or protein-based vaccines. The use of recombinant proteins holds a number of production advantages including ease of scalability, but requires an adjuvant inducing cell-mediated immune responses. A number of promising novel adjuvant formulations have recently been designed and show evidence of induction of cellular immune responses in humans. A common trait of effective TB adjuvants including those already in current clinical testing is a two-component approach combining a delivery system with an appropriate immunomodulator. This review summarizes the status of current TB adjuvant research with a focus on the division of labor between delivery systems and immunomodulators. PMID:26596558

    The use of adjuvants that rescue antibiotics against multidrug-resistant (MDR) pathogens is a promising combination strategy for overcoming bacterial resistance. While the combination of β-lactam antibiotics and β-lactamase inhibitors has been successful in restoring antibacterial efficacy in MDR bacteria, the use of adjuvants to restore fluoroquinolone efficacy in MDR Gram-negative pathogens has been challenging. We describe tobramycin-ciprofloxacin hybrid adjuvants that rescue the activity of fluoroquinolone antibiotics against MDR and extremely drug-resistant Pseudomonas aeruginosa isolates in vitro and enhance fluoroquinolone efficacy in vivo. Structure-activity studies reveal that the presence of both tobramycin and ciprofloxacin, which are separated by a C12 tether, is critical for the function of the adjuvant. Mechanistic studies indicate that the antibacterial modes of ciprofloxacin are retained while the role of tobramycin is limited to destabilization of the outer membrane in the hybrid.

    1993-01-01

    Clinical trials of adjuvant chemotherapy for breast cancer have shown a prolonged disease-free interval but no improvement in survival. This review of the evidence indicates that adjuvant therapy induces an antineoplastic drug resistance that makes "salvage" therapy less effective. The benefit that is seen only in group statistics, not in an individual, must be weighed against the harm an individual incurs from the chemotherapy.

  12. Physician Beliefs and Practices for Adjuvant and Salvage Radiation Therapy After Prostatectomy

    International Nuclear Information System (INIS)

    Purpose: Despite results of randomized trials that support adjuvant radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer with adverse pathologic features (APF), many clinicians favor selective use of salvage RT. This survey was conducted to evaluate the beliefs and practices of radiation oncologists (RO) and urologists (U) regarding RT after RP. Methods and Materials: We designed a Web-based survey of post-RP RT beliefs and policies. Survey invitations were e-mailed to a list of 926 RO and 591 U. APF were defined as extracapsular extension, seminal vesicle invasion, or positive surgical margin. Differences between U and RO in adjuvant RT recommendations were evaluated by comparative statistics. Multivariate analyses were performed to evaluate factors predictive of adjuvant RT recommendation. Results: Analyzable surveys were completed by 218 RO and 92 U (overallresponse rate, 20%). Adjuvant RT was recommended based on APF by 68% of respondents (78% RO, 44% U, p <0.001). U were less likely than RO to agree that adjuvant RT improves survival and/or biochemical control (p < 0.0001). PSA thresholds for salvage RT were higher among U than RO (p < 0.001). Predicted rates of erectile dysfunction due to RT were higher among U than RO (p <0.001). On multivariate analysis, respondent specialty was the only predictor of adjuvant RT recommendations. Conclusions: U are less likely than RO to recommend adjuvant RT. Future research efforts should focus on defining the toxicities of post-RP RT and on identifying the subgroups of patients who will benefit from adjuvant vs. selective salvage RT.

    Purpose: Despite results of randomized trials that support adjuvant radiation therapy (RT) after radical prostatectomy (RP) for prostate cancer with adverse pathologic features (APF), many clinicians favor selective use of salvage RT. This survey was conducted to evaluate the beliefs and practices of radiation oncologists (RO) and urologists (U) regarding RT after RP. Methods and Materials: We designed a Web-based survey of post-RP RT beliefs and policies. Survey invitations were e-mailed to a list of 926 RO and 591 U. APF were defined as extracapsular extension, seminal vesicle invasion, or positive surgical margin. Differences between U and RO in adjuvant RT recommendations were evaluated by comparative statistics. Multivariate analyses were performed to evaluate factors predictive of adjuvant RT recommendation. Results: Analyzable surveys were completed by 218 RO and 92 U (overallresponse rate, 20%). Adjuvant RT was recommended based on APF by 68% of respondents (78% RO, 44% U, p <0.001). U were less likely than RO to agree that adjuvant RT improves survival and/or biochemical control (p < 0.0001). PSA thresholds for salvage RT were higher among U than RO (p < 0.001). Predicted rates of erectile dysfunction due to RT were higher among U than RO (p <0.001). On multivariate analysis, respondent specialty was the only predictor of adjuvant RT recommendations. Conclusions: U are less likely than RO to recommend adjuvant RT. Future research efforts should focus on defining the toxicities of post-RP RT and on identifying the subgroups of patients who will benefit from adjuvant vs. selective salvage RT.

    Potentiation of the antibody response to inactivated bovine viral diarrhea virus by immunological adjuvants was studied in guinea pigs and cattle. The inactivated bovine viral diarrhea virus alone was demonstrated to be a weak immunogen. Addition of either 2 mg per mL diethylaminoethyl-dextran or 5% alhydrogel to inactivated bovine viral diarrhea virus did not or only slightly stimulated the antibody response; the combined adjuvants induced a significantly higher titer.

  17. [Trends in pharmaceutical care for men].

    2016-08-01

    Over the past few years, perceptible changes - both fundamental and specific - have taken place in pharmaceutical care for men. While the most striking difference persists, namely that between somatic drug therapies for men and drugs for the treatment of psychological disorders and diseases, the large discrepancies that long existed between the quantities prescribed for men and women have meanwhile not only evened out, but men are even prescribed larger quantities than women if they undergo drug therapy. An analysis of the drugs prescribed particularly for men revealed that they are primarily prescribed for the treatment of cardiovascular diseases (hypertension and cardiac insufficiency) and metabolic disorders (diabetes, gout), especially in elderly patients. The evaluation also showed that the drugs prescribed most frequently for younger men also included psychostimulants and antidepressants, such as SSRIs, for diagnoses of ADHD and depression.Besides these prescribed medicaments, other drugs must also be taken into account that reflect men's gender-specific everyday needs. These include drugs for treating erectile dysfunction, hair growth products or drugs for male menopause or to build muscle. The sometimes serious undesired effects of these products are often given small attention because of the desired benefit of supporting the perceived male role. While hormones are widely used in anabolic steroids, the use of hormones in contraceptive pills for men is evidently still far away from the aforementioned trends in pharmaceutical care for men.

    It should come as no surprise that the ancient Greek word for drug, pharmakon, meant remedy. But this same word also meant poison as well as magical charm. We speak of heart attacks and of a long road to recovery. These meanings and phrases are reflective of how society conceives of illness and medical therapies. Metaphors and myths of magic, sports and journey are prevalent in medical terminology and they permeate pharmaceutical advertising. This research investigates the conceptual metaphors that are present in advertisements for pharmaceuticals, both those directed to consumers as well as those directed to physicians, for a broad range of drugs and medical conditions. This research employed a content analysis of advertisements appearing in popular consumer magazines as well as in physician journals and an analysis of online consumer drug reviews. The research concludes with a discussion of the similarities and differences among the conceptual metaphors in consumer versus physician ads, across different medical conditions, and the impact of specific metaphors on consumers' understanding of illness and drug therapies.

    2010-07-01

    Full Text Available Pharmaceuticals are a class of emerging environmental contaminants that are extensively and increasingly being used in human and veterinary medicine and are released continuously into the environment. A variety of pharmaceuticals have been detected in many environmental samples worldwide. The establishment of chemical analysis methods able to determine more polar compounds allow the determination and identification of trace quantities of drugs and their metabolites. Most regulatory agencies require that environmental risk assessment is performed as an integral part of their approval procedures for the marketing for medicinal products. Marketing approval for medicinal products in the European Union is regulated by the Directive 2001/83/EC. Based on the Directive, the European Medicines Agency (EMA has published guidelines describing the procedure for the environmental risk assessment for medicinal products marketed in the EU. The requirements for the Environmental risk assessment (ERA in Croatia are regulated by the Medicinal Products Act (Official Gazette No. 71/07 and the Ordinance on the Procedure and Method for Granting Marketing Authorisations for Medicinal Products (Official Gazette No. 113/08.

  2. Old Yet New--Pharmaceuticals from Plants

    Science.gov (United States)

    Houghton, Peter J.

    2001-02-01

    Plants or their crude extracts have been used since prehistory to treat human ailments. Plants are still used in this way in many parts of the world, but Western scientific medicine has tended to isolate active compounds, or make derivatives of them, for use as drugs. Compounds produced by the plant have been important pharmaceuticals since the isolation of morphine almost two hundred years ago and new naturally occurring compounds such as paclitaxel are continually being introduced commercially. Bioactive molecules may also be produced from chemicals found in plants by chemical modification using synthetic chemistry or microorganisms (as in the production of steroids). A third major contribution of plant chemicals to drugs is their utilization as templates for the design of new compounds made by synthesis (e.g. the discovery of aspirin and related compounds from substances in willow bark). New pharmaceuticals from plants are being discovered by examining traditional medicines and by large-scale bioassay screening processes. In addition, the chemical survival systems of plants that exist in hostile environments are receiving increasing attention as leads to discover active compounds. The knowledge of botanical relationships helps find new sources of known compounds of interest and novel compounds with similar structures from related species. Future prospects for the discovery of new compounds from plants are broadened by the new technologies of gene manipulation, tissue culture, and combinatorial chemistry, so it is very likely that natural products from plants will continue to play an important role in the fight against disease.

  3. Pharmaceutical wastewater treatment: a physicochemical study

    International Nuclear Information System (INIS)

    A physicochemical study for the treatment of pharmaceutical wastewater was performed. Objective of the laboratory investigation was to study the removal of color, Total Dissolved Solids (TDS), Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), turbidity and phenol and bring them up to the allowable limits for reuse purposes. Efficiency of coagulation, flocculation, sedimentation, sand filtration followed by activated carbon adsorption was determined. It was found that tested coagulants (alum, ferric chloride, and ferrous sulphate) are not much effective and required high dosage for the removal; of TSS, BOD, COD and turbidity. Alum was found to be more effective among tested coagulants and reduce TSS, BOD, COD and turbidity 79.6%, 34.8, 48.6% and 69.2% respectively. Sand filtration further reduced the studied parameters 97.7%, 95.7%, 93.9% and 76.9% respectively. As the concentration of phenol in the studied pharmaceutical wastewater was 100 mg/l, granular activated carbon was used to remove phenol up to the allowable limit for reuse purpose. Activated carbon adsorption further reduces phenol, TDS, TSS, BOD, and COD up to 99.9%, 99.1%, 21.4%, 81.3% and 71.1% respectively. High removal of color observed after activated carbon adsorption. It was concluded that the suggested treatment scheme is suitable to bring the effluent quality up to the water quality standards. (author)

    Full Text Available Protein-based vaccines offer a safer alternative to live-attenuated or inactivated vaccines but have limited immunogenicity. The identification of adjuvants that augment immunogenicity, specifically in a manner that is durable and antigen-specific, is therefore critical for advanced development. In this study, we use the filovirus virus-like particle (VLP as a model protein-based vaccine in order to evaluate the impact of four candidate vaccine adjuvants on enhancing long term protection from Ebola virus challenge. Adjuvants tested include poly-ICLC (Hiltonol, MPLA, CpG 2395, and alhydrogel. We compared and contrasted antibody responses, neutralizing antibody responses, effector T cell responses, and T follicular helper (Tfh cell frequencies with each adjuvant's impact on durable protection. We demonstrate that in this system, the most effective adjuvant elicits a Th1-skewed antibody response and strong CD4 T cell responses, including an increase in Tfh frequency. Using immune-deficient animals and adoptive transfer of serum and cells from vaccinated animals into naïve animals, we further demonstrate that serum and CD4 T cells play a critical role in conferring protection within effective vaccination regimens. These studies inform on the requirements of long term immune protection, which can potentially be used to guide screening of clinical-grade adjuvants for vaccine clinical development.

    2016-01-01

    Aluminium adjuvants remain the most widely used and effective adjuvants in vaccination and immunotherapy. Herein, the particle size distribution (PSD) of aluminium oxyhydroxide and aluminium hydroxyphosphate adjuvants was elucidated in attempt to correlate these properties with the biological responses observed post vaccination. Heightened solubility and potentially the generation of Al3+ in the lysosomal environment were positively correlated with an increase in cell mortality in vitro, potentially generating a greater inflammatory response at the site of simulated injection. The cellular uptake of aluminium based adjuvants (ABAs) used in clinically approved vaccinations are compared to a commonly used experimental ABA, in an in vitro THP-1 cell model. Using lumogallion as a direct-fluorescent molecular probe for aluminium, complemented with transmission electron microscopy provides further insight into the morphology of internalised particulates, driven by the physicochemical variations of the ABAs investigated. We demonstrate that not all aluminium adjuvants are equal neither in terms of their physical properties nor their biological reactivity and potential toxicities both at the injection site and beyond. High loading of aluminium oxyhydroxide in the cytoplasm of THP-1 cells without immediate cytotoxicity might predispose this form of aluminium adjuvant to its subsequent transport throughout the body including access to the brain.

    Full Text Available We sought to establish a model of inflammatory bowel disease by augmenting the activity of the local immune system with Freund's complete adjuvant, and to determine if inducible nitric oxide synthase (iNOS expression and peroxynitrite formation accompanied the inflammatory condition. In anaesthetized guinea-pigs, a loop of distal ileum received intraluminal 50% ethanol followed by Freund's complete adjuvant. Control animals were sham operated. When the animals were killed 7 or 14 days later, loop lavage fluid was examined for nitrite and PGE2 levels; mucosal levels of granulocyte and macrophages were estimated by myeloperoxidase (MPO and N-acetyl-D-glucosaminidase (NAG activity, respectively. Cellular localization if iNOS and peroxynitrite formation were determined by immunohistochemistry with polyclonal antibodies directed against peptide epitopes of mouse iNOS and nitrotyrosine, respectfully. Adjuvant administration resulted in a persistent ileitis, featuring gut thickening, crypt hyperplasia, villus tip swelling and disruption, and cellular infiltration. Lavage levels of PGE2 and nitrite were markedly elevated by adjuvant treatment. Immunoreactive iNOS and nitrotyrosine bordered on detectability in normal animals but were markedly evident with adjuvant treatment at day 7 and particularly day 14. Immunohistochemistry suggested that enteric neurons and epithelia were major sites of iNOS activity and peroxynitrite formation. We conclude that local administration of adjuvant establishes a chronic ileitis. Inducible nitric oxide synthase may contribute to the inflammatory process.

    Although glycoconjugate vaccines are generally very efficacious, there is still a need to improve their efficacy, especially in eliciting a strong primary antibody response. We have recently described a new type of vaccine adjuvant based on a TLR7 agonist adsorbed to alum (Alum-TLR7), which is highly efficacious at enhancing immunogenicity of protein based vaccines. Since no adjuvant has been shown to potentiate the immune response to glycoconjugate vaccines in humans, we investigated if Alum-TLR7 is able to improve immunogenicity of this class of vaccines. We found that in a mouse model Alum-TLR7 greatly improved potency of a CRM197-MenC vaccine increasing anti-MenC antibody titers and serum bactericidal activity (SBA) against MenC compared to alum adjuvanted vaccine, especially with a low dose of antigen and already after a single immunization. Alum-TLR7 also drives antibody response towards Th1 isotypes. This adjuvant was also able to increase immunogenicity of all polysaccharides of a multicomponent glycoconjugate vaccine CRM197-MenACWY. Furthermore, we found that Alum-TLR7 increases anti-polysaccharide immune response even in the presence of a prior immune response against the carrier protein. Finally, we demonstrate that Alum-TLR7 adjuvant effect requires a functional TLR7. Taken together, our data support the use of Alum-TLR7 as adjuvant for glycoconjugate vaccines. PMID:27439378

    Aluminum oxyhydroxide (Alhydrogel(®)) is a nano-crystalline compound forming aggregates that has been introduced in vaccine for its immunologic adjuvant effect in 1926. It is the most commonly used adjuvant in human and veterinary vaccines but mechanisms by which it stimulates immune responses remain ill-defined. Although generally well tolerated on the short term, it has been suspected to occasionally cause delayed neurologic problems in susceptible individuals. In particular, the long-term persistence of aluminic granuloma also termed macrophagic myofasciitis is associated with chronic arthromyalgias and fatigue and cognitive dysfunction. Safety concerns largely depend on the long biopersistence time inherent to this adjuvant, which may be related to its quick withdrawal from the interstitial fluid by avid cellular uptake; and the capacity of adjuvant particles to migrate and slowly accumulate in lymphoid organs and the brain, a phenomenon documented in animal models and resulting from MCP1/CCL2-dependant translocation of adjuvant-loaded monocyte-lineage cells (Trojan horse phenomenon). These novel insights strongly suggest that serious re-evaluation of long-term aluminum adjuvant phamacokinetics and safety should be carried out. PMID:26948677

Pharmacy education should equip students with the knowledge, skills, and attitudes they need to practise pharmaceutical care competently. Objective: To investigate pharmacy students’ attitudes towards pharmaceutical care, perceptions of their preparedness to perform pharmaceutical care competencies, opinions about the importance of the various pharmaceutical care activities, and the barriers to its implementation in Kuwait. Methods: A descriptive, cross-sectional survey of pharmacy students (n=126 was conducted at Faculty of Pharmacy, Kuwait University. Data were collected via a pre-tested self-administered questionnaire. Descriptive statistics including percentages, medians and means Likert scale rating (SD were calculated and compared using SPSS, version 19. Statistical significance was accepted at a p value of 0.05 or lower. Results: The response rate was 99.2%. Pharmacy students expressed overall positive attitudes towards pharmaceutical care. They felt prepared to implement the various aspects of pharmaceutical care, with the least preparedness in the administrative/management aspects. Perceived pharmaceutical care competencies grew as students progressed through the curriculum. The students also appreciated the importance of the various pharmaceutical care competencies. They agreed/strongly agreed that the major barriers to the integration of pharmaceutical care into practice were lack of private counseling areas or inappropriate pharmacy layout (95.2%, lack of pharmacist time (83.3%, organizational obstacles (82.6%, and pharmacists’ physical separation from patient care areas (82.6%. Conclusion: Pharmacy students’ attitudes and perceived preparedness can serve as needs assessment tools to guide curricular change and improvement. Student pharmacists at Kuwait University

Methods: Retrospective, descriptive, case-control study evaluating 210 patients, of whom 70 received intrasite vancomycin (case group and 140 were controls. It was made a follow up for at least one year, reviewing the physical and electronic records. Data were tabulated in spreadsheets (Excel including all variables and the statistical analysis was made with Epi InfoTM 7 to calculate the odds ratio. Results: Seven cases of deep infection occurred in the control group and none was found in the case group (odds ratio [95% confidence interval]: 0.1262 [0.007-2.24], P = 0.1585. Among the predisposing factors, diabetes and surgical time were the most relevant. Conclusions: Intrasite use of vancomycin has a protective effect against deep infection in patients undergoing lumbar fusion surgery without presenting considerable side effects.

  14. Postoperative adjuvant radiotherapy and 5-fluorouracil chemotherapy for rectal carcinoma

    International Nuclear Information System (INIS)

    Postoperative combined modality therapy with radiotherapy and 5-fluorouracil (5FU) chemotherapy is an effective adjuvant approach that reduces locoregional and distant metastatic disease in patients with high-risk rectal carcinoma. However, this approach results in a treatment regimen of at least 6 months' duration. The present prospective study investigates the integration of radiotherapy and 5FU chemotherapy in a protocol designed to minimize toxicity and reduce the overall treatment time. A total of 40 patients with TNM stage 11 or 111 disease receives postoperative radiotherapy at four fractions per week with weekly 5FU bolus injections delivered on the fifth non radiotherapy day. Patients also received systemic chemotherapy with leucovorin both before and after pelvic irradiation, with the total treatment duration extending for only 18 weeks. Patients were able to complete radiotherapy in 90% of cases, while the delivery of full-dose chemotherapy was achievable in the vast majority. The incidence of haematologic and gastrointestinal toxicities requiring the cessation of treatment was acceptable. With a median follow-up of 20.9 months among surviving patients, the estimated progression-free and overall survival at 2 years were 71% and 79%, respectively.

    2002-06-01

    Animal models have shown the potential use of monophosphoryl lipid A (MPL), a detoxified bacterial lipopolysaccharide, as a vaccine adjuvant. Immunostimulatory activity with diverse effects on the cellular elements of the immune system has been demonstrated and a range of vaccines incorporating MPL, including allergy vaccines, are currently under clinical evaluation. A series of preclinical safety investigations was performed to support clinical use of MPL as used in allergy vaccines and comprised cardiovascular/respiratory assessment in dog (up to 100 microg/kg/day); repeat-dose toxicity in rat, rabbit, and dog (up to 2500 and 1200 microg/kg/day in the rat and dog, respectively); reproduction toxicity in rat and rabbit (up to 100 microg/kg/day); and genotoxicity studies. Overall, repeat-dose toxicity studies in the rat and dog showed expected immunostimulatory effects and/or signs of toxicity associated with overstimulation of the immune system (notably increased spleen weight and white blood cell values). Studies in the rabbit with weekly doses of MPL produced no effects. MPL was shown to have no adverse effects on cardiovascular/respiratory function, reproduction, and genotoxicity.

    Although adverse effects and glucocorticoid resistance cripple their chronic use, glucocorticoids form the mainstay therapy for acute and chronic inflammatory disorders, and play an important role in treatment protocols of both lymphoid malignancies and as adjuvant to stimulate therapy tolerability in various solid tumors. Glucocorticoid binding to their designate glucocorticoid receptor (GR), sets off a plethora of cell-specific events including therapeutically desirable effects, such as cell death, as well as undesirable effects, including chemotherapy resistance, systemic side effects and glucocorticoid resistance. In this context, selective GR agonists and modulators (SEGRAMs) with a more restricted GR activity profile have been developed, holding promise for further clinical development in anti-inflammatory and potentially in cancer therapies. Thus far, the research into the prospective benefits of selective GR modulators in cancer therapy limped behind. Our review discusses how selective GR agonists and modulators could improve the therapy regimens for lymphoid malignancies, prostate or breast cancer. We summarize our current knowledge and look forward to where the field should move to in the future. Altogether, our review clarifies novel therapeutic perspectives in cancer modulation via selective GR targeting.

    1. We investigated the difference in hepatobiliary transport of methotrexate in normal and adjuvant arthritis (AA) rats and substantiated the expression level of multidrug resistance-associated protein 2 (MRP2) in the liver. 2. Biliary clearance of methotrexate in normal and AA rats was calculated from plasma concentrations and biliary excretion following intravenous infusion and hepatic uptake clearance was estimated from an integration plot using methotrexate concentrations in plasma and liver. 3. Biliary clearance of methotrexate in AA rats was 2.30 +/- 0.23 ml min(-1) kg(-1) (mean SD) and significantly lower than in normal rats (8.42 +/- 0.81 ml min(-1) kg(-1)). The uptake clearance of methotrexate in AA rats was also lower than in normal rats (0.138 versus 0.278 ml min(-1) g liver(-1)). 4. MRP2 in the liver was detected by fluorescein isothiocyanate-labelled antibody and visualized using a confocal laser microscope system. The expression level of MRP2 in AA rats was very low compared with normal rats, indicating a down-regulation in AA rats. 5. In conclusion, biliary clearance of methotrexate was decreased due to the lower activities in both uptake and canalicular secretion, suggesting that several active transporters in the liver, including MRP2, are down-regulated in AA rats.

    Global pharmaceutical industry has relocated from the west to Asian countries to ensure competitive advantage. This industrial relocation has posed serious threats to the environment. The present study was carried out to assess the possible pharmaceutical contamination in the environment of emerging pharmaceutical manufacturing countries (Bangladesh, China, India and Pakistan). Although these countries have made tremendous progress in the pharmaceutical sector but most of their industrial units discharge wastewater into domestic sewage network without any treatment. The application of untreated wastewater (industrial and domestic) and biosolids (sewage sludge and manure) in agriculture causes the contamination of surface water, soil, groundwater, and the entire food web with pharmaceutical compounds (PCs), their metabolites and transformed products (TPs), and multidrug resistant microbes. This pharmaceutical contamination in Asian countries poses global risks via product export and international traveling. Several prospective research hypotheses including the development of new analytical methods to monitor these PCs/TPs and their metabolites, highly resistant microbial strains, and mixture toxicity as a consequence of pharmaceutical contamination in these emerging pharmaceutical exporters have also been proposed based on the available literature.

    The removal of five selected pharmaceuticals, viz., carbamazepine, clofibric acid, diclofenac, ibuprofen, and ketoprofen was examined by batch sorption experiments onto a synthesized mesoporous silica SBA-15. SBA-15 was synthesized and characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), N{sub 2} adsorption-desorption measurement, and point of zero charge (PZC) measurement. Pharmaceutical adsorption kinetics was rapid and occurred on a scale of minutes, following a pseudo-second-order rate expression. Adsorption isotherms were best fitted by the Freundlich isotherm model. High removal rates of individual pharmaceuticals were achieved in acidic media (pH 3-5) and reached 85.2% for carbamazepine, 88.3% for diclofenac, 93.0% for ibuprofen, 94.3% for ketoprofen, and 49.0% for clofibric acid at pH 3 but decreased with increase in pH. SBA-15 also showed high efficiency for removal of a mixture of 5 pharmaceuticals. Except for clofibric acid (35.6%), the removal of pharmaceuticals in the mixture ranged from 75.2 to 89.3%. Based on adsorption and desorption results, the mechanism of the selected pharmaceuticals was found to be a hydrophilic interaction, providing valuable information for further studies to design materials for the purpose. The results of this study suggest that mesoporous-silica-based materials are promising adsorbents for removing pharmaceuticals from not only surface water but also wastewater of pharmaceutical industrial manufactures.

    2015-01-01

    Studies have been conducted to assess patient satisfaction with compounded pharmaceuticals and to directly compare compounded pharmaceuticals with their comparable commercial pharmaceuticals. Yet, the economic value of or potential for economic value derived from compounded pharmaceuticals relative to commercial pharmaceuticals is still not known. Therefore, the purpose of this study was to assess and compare compounding and non-compounding pharmacists' perceptions of the economic value of compounded preparations relative to commercial products. In-depth interviews with 10 compounding pharmacists and physicians who prescribe compounded prescription pharmaceutical preparations were conducted to help develop a self-administered questionnaire distributed to 50 compounding and 50 non-compounding pharmacists. Compounding and non-compounding pharmacists' perceptions differed most often in the context of compounded pharmaceuticals for pediatric patients. However, both groups responded with moderate agreement that compounded prescription treatments are more profitable for the pharmacy than commercial prescription treatments in most therapeutic areas. This research sought to understand the perception of pharmacists of areas for potential direct and indirect economic cost savings as a result of compounding. For all items whereby compounding and non-compounding pharmacists' ratings were significantly different, compounding pharmacists more strongly believed that compounding pharmaceuticals offered benefit and vice versa. The differences in ratings that were most common were those that directly compared the economic value of compounding and commercial pharmaceuticals, with compounding pharmacists more strongly agreeing with the potential cost savings associated with compounded pharmaceuticals. Based on these findings, prescription compounds are believed to have a benefit to the health system by those who provide them. Future research should proactively explore the economic

    2008-09-01

    Pharmaceutical residues may have serious impacts on nontarget biological organisms in aquatic ecosystems, and have therefore precipitated numerous investigations worldwide. Many pharmaceutical compounds available on the market need to be prioritized based on their potential ecological and human health risks in order to develop sound management decisions. We prioritized veterinary pharmaceuticals in Korea by their usage, potential to enter the environment, and toxicological hazard. Twenty compounds were identified in the top priority class, most of which were antibiotics. Among these compounds, 8 were identified as deserving more immediate attention: amoxicillin, enramycin, fenbendazole, florfenicol, ivermectin, oxytetracycline, tylosin, and virginiamycin. A limitation of this study is that we initially screened veterinary pharmaceuticals by sales tonnage for veterinary use only. However, this is the first attempt to prioritize veterinary pharmaceuticals in Korea, and it provides important concepts for developing environmental risk management plans for such contaminants in aquatic systems.

    2014-01-01

    The purpose of this review work is to give an overview of the research reported on bioprocesses for the treatment of domestic or industrial wastewaters (WW) containing pharmaceuticals. Conventional WW treatment technologies are not efficient enough to completely remove all pharmaceuticals from water. Indeed, these compounds are becoming an actual public health problem, because they are more and more present in underground and even in potable waters. Different types of bioprocesses are described in this work: from classical activated sludge systems, which allow the depletion of pharmaceuticals by bio-degradation and adsorption, to enzymatic reactions, which are more focused on the treatment of WW containing a relatively high content of pharmaceuticals and less organic carbon pollution than classical WW. Different aspects concerning the advantages of membrane bioreactors for pharmaceuticals removal are discussed, as well as the more recent studies on enzymatic membrane reactors to the depletion of these recalcitrant compounds.

    Landfill leachates might contain pharmaceuticals due to the expired or unwanted drugs were disposed of at landfills. These pharmaceuticals might pose a threat to soil and groundwater. Therefore, this study investigated the distributions of pharmaceutical residues and toxicities among four typical municipal landfill leachates. Twenty six pharmaceuticals were investigated in this study and fifteen of them were found in all samples from four leachates. In addition, ampicillin and methylenedioxymethamphetamine (MDMA) were detected in urban landfills (A1 and A2) but were not in rural and suburb landfills (B and C). On the other hand, some compounds were much more abundant in suburb/rural landfill leachates than those in urban landfills including diclofenac, gemfibrozil and amphetamine. Landfill leachate treatment plants could not remove most of the pharmaceuticals effectively. Landfill leachates without proper treatments would have significant adverse health impacts on human and aquatic life. PMID:27026494

    Full Text Available Green chemistry expresses an area of research developing from scientific discoveries about pollution awareness and it utilizes a set of principles that reduces or eliminates the use or generation of hazardous substances in all steps of particular synthesis or process. Chemists and medicinal scientists can greatly reduce the risk to human health and the environment by following all the valuable principles of green chemistry. The most simple and direct way to apply green chemistry in pharmaceuticals is to utilize eco-friendly, non-hazardous, reproducible and efficient solvents and catalysts in synthesis of drug molecules, drug intermediates and in researches involving synthetic chemistry. Microwave synthesis is also an important tool of green chemistry by being an energy efficient process.

  6. The pharmaceutical industry as a medicines provider.

    Henry, David; Lexchin, Joel

    2002-11-16

    Rising prices of medicines are putting them beyond the reach of many people, even in rich countries. In less-developed countries, millions of individuals do not have access to essential drugs. Drug development is failing to address the major health needs of these countries. The prices of patented medicines usually far exceed the marginal costs of their production; the industry maintains that high prices and patent protection are necessary to compensate for high development costs of innovative products. There is controversy over these claims. Concerns about the harmful effects of the international system of intellectual property rights have led the World Trade Organization to relax the demands placed on least developed countries, and to advocate differential pricing of essential drugs. How these actions will help countries that lack domestic production capacity is unclear. Better access to essential drugs may be achieved through voluntary licensing arrangements between international pharmaceutical companies and manufacturers in developing countries. PMID:12443614

    Lakdawalla, Darius; Sood, Neeraj; Gu, Qian

    2013-12-01

    We explore how and to what extent prescription drug insurance expansions affect incentives for pharmaceutical advertising. When insurance expansions make markets more profitable, firms respond by boosting advertising. Theory suggests this effect will be magnified in the least competitive drug classes, where firms internalize a larger share of the benefits from advertising. Empirically, we find that the implementation of Part D coincides with a 14-19% increase in total advertising expenditures. This effect is indeed concentrated in the least competitive drug classes. The additional advertising raised utilization among non-elderly patients outside the Part D program by about 3.6%. This is roughly half of the direct utilization effect of Part D on elderly beneficiaries. The results suggest the presence of considerable spillover effects from publicly subsidized prescription drug insurance on the utilization and welfare of consumers outside the program.

    Bertrand, Nicolas; Gauthier, Marc A; Bouvet, Céline; Moreau, Pierre; Petitjean, Anne; Leroux, Jean-Christophe; Leblond, Jeanne

    2011-10-30

    Macromolecular binders consist of polymers, dendrimers, and oligomers with binding properties for endogenous or exogenous substrates. This field, at the frontier of host/guest chemistry and pharmacology, has met a renewed interest in the past decade due to the clinical success of several sequestrants, like sevelamer hydrochloride (Renagel®) or sugammadex (Bridion®). In many instances, multivalent binding by the macromolecular drugs can modify the properties of the substrate, and may prevent it from reaching its site of action and/or trigger a biological response. From small (e.g., ions) to larger substrates (e.g., bacteria and cells), this review presents the state-of-the-art of macromolecular binders and provides detailed illustrative examples of recent developments bearing much promise for future pharmaceutical applications.

    1998-12-01

    Four simple and sensitive visible spectrophotometric methods (A-D) have been described for the assay of azathioprine (ATP) either in pure form or in pharmaceutical formulations. Methods A and B are based on the oxidation of ATP with excess N-bromosuccinimide (NBS) or chloramine-T (CAT) and determining the consumed NBS or CAT with a decrease in colour intensity of celestine blue (CB) (method A) or gallocyanine (GC) (method B), respectively. Methods C and D are based on the diazotisation of reduced azathioprine (RATP) with excess nitrous acid and estimating either the consumed nitrous acid (HNO(2)) with cresyl fast violet acetate (CFVA) (method C) or by coupling reaction of the diazonium salt formed with N-1-naphthyl ethylene diamine dihydrochloride (NED) (method D). All of the variables have been optimized and the reactions presented. The concentration measurements are reproducible within a relative standard deviation of 1.0%. Recoveries are 99.2-100.3%.

  10. Pancreatin irradiation for medical and pharmaceutical applications

    International Nuclear Information System (INIS)

    Pancreatin is an enzyme mix conformed substance used in medical and pharmaceutical applications principally. Due to its origin and processing method, pancreatin possibly requires to undergo a decontamination process. Thus, sample of powered pancreatin were packed in polyethylene bags and gamma irradiated at 2, 3, 5, 6, 7, 8, 13 y 25 kGy. Microbiological and physico-chemical tests specified in the US Pharmacopea were performed to the irradiated samples and control in order to determine the optimum decontamination dose which will permit the commercial use of the product. It was determined that 5 kGy as minimum dose was adequate to reduce in 3 log cycles the initial bioburden of the product, which was composed principally by aerobic mesophiles, specifically sporulated bacilli. Moreover, results of assays involved loss of drying, enzymatic activity, colour and odour performed in irradiated samples showed no significant alterations respecting the control. (author)

    Electroanalytical methods based on square-wave adsorptive-stripping voltammetry (SWAdSV) and flow-injection analysis with SWAdSV detection (FIA-SWAdSV) were developed for the determination of paroxetine (PRX). The methods were based on the reduction of PRX at a mercury drop electrode at -1.55V versus Ag/AgCl, in a borate buffer of pH 8.8, and the possibility of accumulating the compound at the electrode surface. Because the presence of dissolved oxygen did not interfere significantly with the analysis, it was also possible to determine PRX using FIA-SWAdSV. This method enables analysis of up to 120 samples per hour at reduced costs. Both methods developed were validated and successfully applied to the quantification of PRX in pharmaceutical products.

  13. New applications for accelerators in pharmaceutical processes

    International Nuclear Information System (INIS)

    In-line sterilization tunnels using electron beam have become a reality since the development of low energy and medium energy accelerators small enough to fit into self-shielded units which can be integrated into production lines. These systems have many advantages for the health care industry since they provide fast continuous room temperature sterilization which is simple to validate and traceable. Economies are apparent in terms of time, logistics, fixed assets costs, labour costs etc. Environmental impact is considered low. Medium energy systems for core sterilization of medical devices, syringes or vials have already been installed. The low energy surface sterilization systems which have been installed on 19+ pre-filled syringe lines have recently benefited from technology improvements which increase efficiency. The presentation will introduce electron beam sterilization technology and its practical aspects for pharmaceutical manufacturers, i.e., dosimetry, validation, interfaces, monitoring and recording.

    2016-01-01

    This book serves as a reference text for regulatory, industry and academic statisticians and also a handy manual for entry level Statisticians. Additionally it aims to stimulate academic interest in the field of Nonclinical Statistics and promote this as an important discipline in its own right. This text brings together for the first time in a single volume a comprehensive survey of methods important to the nonclinical science areas within the pharmaceutical and biotechnology industries. Specifically the Discovery and Translational sciences, the Safety/Toxiology sciences, and the Chemistry, Manufacturing and Controls sciences. Drug discovery and development is a long and costly process. Most decisions in the drug development process are made with incomplete information. The data is rife with uncertainties and hence risky by nature. This is therefore the purview of Statistics. As such, this book aims to introduce readers to important statistical thinking and its application in these nonclinical areas. The cha...

  15. Modelling of drying processes of pharmaceutical granules. Pharmaceutical Sciences for the Future of Medicines

    Mortier, S.T.F.C.; Vedantam, S.; De Beer, T.;

    Tablets are conventionally produced via consecutive batch process steps. Recent introduction of continuous process equipment is gaining industrial importance in pharmaceutics. Transition to continuous production requires improved understanding of all operations, necessitating the development...... of mechanistic models of multi‐phase systems which in the end allow process control. This contribution focuses on continuous fluidized bed drying of pharmaceutical wet granules. A stepwise approach is used in model development, starting with the drying behaviour of single granules. Experiments to determine...... the drying characteristics were conducted in a continuous fluidized bed dryer at several gas temperatures and velocities. The drying process was found to consist of two subsequent phases: a fast drop in moisture content followed by a slower evaporation. A mechanistic model for single granules [1] yielded...

  16. A vision of the pharmaceutical industry.

    As the financial resources available for looking after the health of an aging population are limited, generic drugs (drugs that are no longer covered by a patent and marketed at a lower price) have come to be used in western countries as a means for meeting growing demand while leaving resources in the health budget for new drugs. In Spain, a law on product patents was introduced in 1992, which is much later than in other countries, and created difficulties in the definition and procedure for gaining approval for generic drugs. Circular 3/97 from the Ministry of Health finally resolved these issues. In this circular, generic pharmaceutical products (GPPs) are clearly defined and identified with a positive commitment towards guaranteeing the ability to interchange original drugs for other cheaper generic products and towards clarifying the Spanish vade mecum. The position of the pharmaceutical industry on generic drugs varies widely and consequently, it is impossible to make a general statement on the view of the industry. However, the commitment of Novartis, given the issues described above and in line with the company's global strategy, is to offer innovation and services to society. This is perfectly compatible with offering health professionals both innovative drugs and generic drugs of a high quality at a lower price, given that registering genetics requires less investment in research and development. In any case, GPPs face an uncertain future in Spain and market forecasts also differ widely, ranging from 15 billion to 80 billion pesetas in the year 2000. It will be necessary to get doctors and pharmacists positively involved, to set up fast structural measures, and to avoid rejection by patients through successful information and marketing.

  19. Generation of "virtual" control groups for single arm prostate cancer adjuvant trials.

    Directory of Open Access Journals (Sweden)

    Zhenyu Jia

    Full Text Available It is difficult to construct a control group for trials of adjuvant therapy (Rx of prostate cancer after radical prostatectomy (RP due to ethical issues and patient acceptance. We utilized 8 curve-fitting models to estimate the time to 60%, 65%, … 95% chance of progression free survival (PFS based on the data derived from Kattan post-RP nomogram. The 8 models were systematically applied to a training set of 153 post-RP cases without adjuvant Rx to develop 8 subsets of cases (reference case sets whose observed PFS times were most accurately predicted by each model. To prepare a virtual control group for a single-arm adjuvant Rx trial, we first select the optimal model for the trial cases based on the minimum weighted Euclidean distance between the trial case set and the reference case set in terms of clinical features, and then compare the virtual PFS times calculated by the optimum model with the observed PFSs of the trial cases by the logrank test. The method was validated using an independent dataset of 155 post-RP patients without adjuvant Rx. We then applied the method to patients on a Phase II trial of adjuvant chemo-hormonal Rx post RP, which indicated that the adjuvant Rx is highly effective in prolonging PFS after RP in patients at high risk for prostate cancer recurrence. The method can accurately generate control groups for single-arm, post-RP adjuvant Rx trials for prostate cancer, facilitating development of new therapeutic strategies.

    Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage Ⅰ-Ⅲ) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX)300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 d1,cisplatin (DDP) 20 mg/m2, d1-5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600-900 mg/d for 1year (adjuvant chemotherapy group). The other 35patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4%in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage Ⅲwas 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage Ⅰ-Ⅱ in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage Ⅲ, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.
