    Full Text Available In the present research, the steroidal anti-asthmatic drug beclomethasone dipropionate was subjected to microbial biotransformation by Aspergillus niger. Beclomethasone dipropionate was transformed into various metabolites first time from microbial transformation. New drug metabolites produced can act as new potential drug molecules and can replace the old drugs in terms of safety, efficacy, and least resistance. They were purified by preparative thin layer chromatography technique, and their structures were elucidated using modern spectroscopic techniques, such as 13C NMR, 1H NMR, HMQC, HMQC, COSY, and NOESY, and mass spectrometry, such as EI-MS. Four metabolites were purified: (i beclomethasone 17-monopropionate, (ii beclomethasone 21-monopropionate, (iii beclomethasone, and (iv 9beta,11beta-epoxy-17,21-dihydroxy-16beta-methylpregna-1,4-diene-3,20-dione 21-propionate.

    The aim of this study was to systematically review the safety and efficacy of inhaled beclomethasone for asthma treatment in pregnant women. We performed a systematic review in Medline, LILACS and SciELO electronic databases in December 2012. A total of 3433 articles were found by using the keywords asthma, pregnancy and beclomethasone. Among these, 1666 were from Medline, via PubMed, and 1767 were from LILACS and SciELO. Nine of these articles were selected. Only one paper suggested an increased foetal risk for congenital malformations, and one other for offspring endocrine and metabolic disturbances. Data are mostly reassuring, supporting the use of glucocorticoid inhalants during pregnancy, and we found no evidence of inferiority in relation to efficacy and safety of beclomethasone compared to other drugs used in pregnant asthmatic women.

    Full Text Available Introduction: Post-operative sore throat and cough are common complications of endotracheal intubation. These conditions may be very distressing for the patient and may lead to unpleasant memories. This study was performed in order to determine whether beclomethasone and lidocaine spray could reduce the frequency of post-operative sore throat and hoarseness after tracheal extubation.  Materials and Methods: Ninety women (18–60 years of age with an American Society of Anesthesiologists (ASA physical status I or II and undergoing elective mastoidectomy were randomized into three groups of 30 patients. The endotracheal tubes in each group were sprayed with 50% beclomethasone, 10% lidocaine hydrochloride, or normal saline (control group before endotracheal intubation. Patients were examined for sore throat (none, mild, moderate, or severe, cough, and hoarseness at 1 and 24 h after extubation.  Results: There was a significantly lower incidence and severity of post-operative sore throat in the beclomethasone group than the lidocaine and control groups (P

    Full Text Available Objectives. The current study aimed to compare the efficacy and safety of a classical anti-inflammatory beclomethasone nasal spray in comparison to a physic-chemical stabilizing ectoine containing nasal spray in the treatment of allergic rhinitis. Design and Methods. This was a noninterventional, open-label, observational trial investigating the effects of beclomethasone or ectoine nasal spray on nasal symptoms and quality of life. Over a period of 14 days, patients were asked to daily document their symptoms. Efficacy and tolerability were assessed by both physicians and patients. Results. Both treatments resulted in a significant decrease of TNSS values. An equivalence test could not confirm the noninferiority of ectoine treatment in comparison with beclomethasone treatment. Although clear symptom reduction was achieved with the ectoine products, the efficacy judgment showed possible advantages for the beclomethasone group. Importantly, tolerability results were comparably good in both groups, and a very low number of adverse events supported this observation. Both treatments resulted in a clear improvement in the quality of life as assessed by a questionnaire answered at the beginning and at the end of the trial. Conclusion. Taken together, it was shown that allergic rhinitis can be safely and successfully treated with beclomethasone and also efficacy and safety were shown for ectoine nasal spray.

    Beclomethasone dipropionate (BDP), which is a member in the inhaled glucocorticosteroid class, is commonly used in the treatment of asthma by pulmonary delivery. The purpose of this study is to prepare ultrafine BDP particles for dry powder inhalation (DPI) administration by combining microfluidic antisolvent precipitation without surfactant, high-pressure homogenization (HPH) and spray drying. T-junction microchannel was adopted for the preparation of needle-like BDP particles. The needle-like particles could be easily broken down into smaller particles during HPH, which were assembled into uniform low-density spherical BDP aggregates by spray drying. The effects of the operation parameters, such as the flow rates of BDP methanol solution and antisolvent, the overall flow rate, the BDP concentration, and the change of the injection phase on BDP particle size were explored. The results indicated that the BDP particle size greatly decreased with the reduction of BDP solution flow rate and the increase of antisolvent flow rate. However, the BDP particle size firstly decreased and then increased with the increase of the overall flow rate and the increase of BDP concentration. Also, BDP solution as the injection phase could form the smaller BDP particles. 10 HPH cycles are enough to forming short rod-like particles. After spray drying, the BDP spherical aggregates with a 2-3 μm size could be achieved. They have an excellent aerosol performance, 2.8 and 1.4 times as many as raw BDP and vacuum-dried BDP particles, respectively. Copyright © 2012 Elsevier B.V. All rights reserved.

    The effects of propellant type, cosolvent content, and air humidity on the morphology and solid phase of the particles produced from solution pressurized metered dose inhalers containing the corticosteroid beclomethasone dipropionate were investigated. The active ingredient was dissolved in the HFA propellants 134a and 227ea with varying levels of the cosolvent ethanol and filled into pressurized metered dose inhalers. Inhalers were actuated into an evaporation chamber under controlled temperature and humidity conditions and sampled using a single nozzle, single stage inertial impactor. Particle morphology was assessed qualitatively using field emission scanning electron microscopy and focused ion beam-helium ion microscopy. Drug solid phase was assessed using Raman microscopy. The relative humidity of the air during inhaler actuation was found to have a strong effect on the particle morphology, with solid spheroidal particles produced in dry air and highly porous particles produced at higher humidity levels. Air humidification was found to have no effect on the solid phase of the drug particles, which was predominantly amorphous for all tested formulations. A critical level of air relative humidity was required to generate porous particles for each tested formulation. This critical relative humidity was found to depend on the amount of ethanol used in the inhaler, but not on the type of propellant utilized. The results indicate that under the right circumstances water vapor saturation followed by nucleated water condensation or ice deposition occurs during particle formation from evaporating propellant-cosolvent-BDP droplets. This finding reveals the importance of condensed water or ice as a templating agent for porosity when particle formation occurs at saturated conditions, with possible implications on the pharmacokinetics of solution pMDIs and potential applications in particle engineering for drug delivery.

The triple combination therapy of inhaled corticosteroids (ICSs, long-acting beta2 agonists (LABAs, and long-acting muscarinic antagonists (LAMAs has become an option for maintenance treatment of COPD and as a “step-up” therapy from single or double combination treatments. There is evidence that triple combination ICS/LABA/LAMA with different inhalers improves lung function, symptoms, and health status and reduces exacerbations. A new triple fixed-dose combination of extrafine beclomethasone dipropionate (100 µg/puff/formoterol fumarate (6 µg/puff/glycopyrronium bromide (12.5 µg/puff has been developed as a hydrofluoroalkane pressurized metered dose inhaler. Two large pivotal studies showed that this extrafine fixed ICS/LABA/LAMA triple combination is superior to fixed ICS/LABA combined therapy and also superior to the LAMA tiotropium in terms of lung function and exacerbation prevention in COPD patients at risk of exacerbation. This review considers the new information provided by these clinical trials of extrafine triple therapy and the implications for the clinical management of COPD patients.

    Allergic rhinitis (AR) is one of the most common chronic respiratory diseases observed in the pediatric population, producing a significant morbidity, and an economic burden due to direct medical costs and indirect costs. Despite the high prevalence of AR in children and the importance of the use of topical intranasal corticosteroids for its treatment, comparative analyses of alternative treatments in pediatric patients, in terms of both cost and effectiveness are lacking. A decision-analysis model was developed to estimate the cost-effectiveness of mometasone furoate nasal spray (MFNS) compared to beclomethasone dipropionate nasal spray (BDNS) for treating pediatric patients with AR over a 12-month period. Effectiveness parameters were obtained from a published study in which authors performed a systematic review of the literature. Cost data were obtained from a hospital's bills and from the national manual of drug prices. The study assumed the perspective of the national healthcare in Colombia. The outcomes were three effectiveness measures summarized in a therapeutic index (TIX). For the base-case analysis, the model showed that compared to BDNS, therapy with MFNS was associated with lower costs (US$229.78 vs. 289.74 average cost per patient over 12 months) and a greater improvement in TIX score (0.9724 vs. 0.8712 score points on average per patient over 12 months), thus leading to dominance. The present analysis shows that in Colombia, compared with BDNS, therapy with MFNS for treating pediatric patients with AR is a dominant strategy because it showed a greater improvement in a TIX reflecting both efficacy and safety, at lower total treatment costs.

    Sixteen patients with 18 attacks of distal ulcerative colitis were treated randomly with either 0.5 mg topically administered beclomethasone dipropionate (BDP) or 5 mg betamethasone phosphate (BMT). The effect of the steroid enemas on adrenocortical function was examined by ACTH tests, which were performed before and 20 days after treatment. At completion of the trial, a marked suppression of the adrenocortical function was found in seven of eight patients treated for nine attacks with BMT but not in any patients in the BDP group (P less than 0.01). The mean posttreatment basal and stimulated plasma cortisol levels in the BMT group were significantly lower as compared with the BDP group. The overall therapeutic response assessed by score systems was comparable in the two treatment groups. It is concluded that, in the topical treatment of ulcerative colitis, BDP is preferable to BMT because it exerts an equal anti-inflammatory action without affecting adrenocortical function.

    Spectrophotometric and TLC-spectrodensitometric methods were developed and validated for the simultaneous determination of beclomethasone dipropionate (BEC) and salbutamol (SAL). The spectrophotometric methods include dual wavelength, ratio difference, constant center coupled with a novel method namely, spectrum subtraction and mean centering with mean percentage recoveries and RSD 99.72±1.07 and 99.70±1.12, 100.25±1.12 and 99.89±1.12, 99.66±1.85 and 99.19±1.32, 100.74±1.26 and 101.06±0.90 for BEC and SAL respectively. The TLC-spectrodensitometric method was based on separation of both drugs on TLC aluminum plates of silica gel 60 F254, using benzene: methanol: triethylamine (10:1.5:0.5 v/v/v) as a mobile phase, followed by densitometric measurements of their bands at 230 nm. The mean percentage recoveries and RSD were 99.07±1.25 and 101.35±1.50 for BEC and SAL respectively. The proposed methods were validated according to ICH guidelines and were applied for the simultaneous analysis of the cited drugs in synthetic mixtures and pharmaceutical preparation. The methods were found to be rapid, specific, precise and accurate and can be successfully applied for the routine analysis of BEC and SAL in their pharmaceutical formulation with no need for prior separation. The results obtained were statistically compared to each other and to that of the reported HPLC method. The statistical comparison showed that there is no significant difference regarding both accuracy and precision. Copyright © 2014 Elsevier B.V. All rights reserved.

    Intranasal corticosteroids are the mainstay of allergic rhinitis (AR) treatment. Their potential to suppress the hypothalamic-pituitary-adrenal axis should be evaluated, especially after long-term daily use in children. To evaluate the effects of treatment with non-aqueous beclomethasone dipropionate (BDP) nasal aerosol on hypothalamic-pituitary-adrenal axis function in children with perennial AR. In this double-blinded, placebo-controlled, parallel-group study, patients (6-11 years old) with perennial AR were randomized (2:1) to BDP nasal aerosol at 80 μg/day (n = 67) or placebo (n = 32). The primary end point was change from baseline in 24-hour serum cortisol (SC) weighted mean for BDP nasal aerosol and placebo after 6 weeks of treatment, which was analyzed in the per-protocol population. The per-protocol population included 97 patients (BDP nasal aerosol, n = 66; placebo, n = 31). Baseline geometric mean SC weighted mean values were similar in the 80-μg/day BDP nasal aerosol and placebo groups (5.97 and 6.47 μg/dL, respectively). After 6 weeks' treatment, geometric mean values were 6.19 and 7.13 μg/dL, respectively, with no decrease from baseline in either group. Geometric mean SC ratio of BDP nasal aerosol at 80 μg/day to placebo was 0.91 (95% confidence interval 0.81-1.03), indicating predefined noninferiority. SC concentration-time profiles were similar for the placebo and 80-μg/day BDP nasal aerosol groups at baseline and week 6. BDP nasal aerosol at 80 μg/day was generally well tolerated. In pediatric patients with perennial AR, 24-hour SC profiles were comparable for BDP nasal aerosol and placebo, indicating that once-daily BDP nasal aerosol treatment did not significantly affect hypothalamic-pituitary-adrenal axis function.

We studied 30 newborn preterms with gestational age <36 weeks, undergoing conventional mechanical ventilation for at least 12 hours. Three sequential inhalations with their medications were executed with an interval of three hours between each. We collected samples of arterial blood for gas analysis, and after endotracheal aspiration, the measurement of respiratory variables was performed in two stages, two hours before and after the last inhalation. Dynamic compliance and the oxygenation index showed no statistically significant difference between before and after the medication, however, the airway resistance group demonstrated a reduction in beclomethasone between the moments before and after the intervention (p=0.03. These results cannot imply that inhaled beclomethasone and furosemide exerted significant influence on lung function and oxygenation in the newborn infants studied.

    States of Haryana, Karnataka, Maharashtra and Rajasthan, and Chennai (capital of Tamil Nadu State), India. To assess the availability, price and affordability of beclomethasone and salbutamol inhalers in five Indian states using a standardised methodology. Data on the availability and price of two essential medicines for asthma, beclomethasone (50 microg/dose) and salbutamol (0.1 mg/dose) inhalers, were collated from five medicine price studies on essential medicines. Beclomethasone and salbutamol inhalers were available in 25% and 30% of public facilities in Rajasthan State only. The procurement price for beclomethasone and salbutamol was respectively 0.74 and 0.56 times the international reference price (IRP). The availability of beclomethasone inhalers was poor in the private sector (10-65%) in four states. The availability of salbutamol inhalers ranged from 20% to 95% as an innovator brand and 83% to 100% as the generic. The price of beclomethasone was 0.87-1.49 times the IRP, while salbutamol cost 0.82-1.12 times the IRP. Purchasing one inhaler each of salbutamol and beclomethasone cost between 1.6 and 2.3 days' wages for the lowest paid government worker. Eighty per cent of the population earn less than this wage. Essential inhalation medicines for asthma were not available in the public sector where low-income populations receive treatment. Steroid inhalers were not readily available in the private sector. Essential inhalation medicines for asthma are not affordable for the majority of the population.

    This prospective randomized case controlled study was conducted to determine the efficacy of antihistamine (azelastine) nasal spray and compare it to steroid (beclomethasone) nasal spray on the symptoms of allergic rhinitis. Seventy five symptomatic patients of allergic rhinitis were included in this study. Diagnosis was made on the basis of history and physical examination. The patients were divided into three groups randomly. Group A was treated with Azelastine nasal spray, Group B was treated with Beclomethasone nasal spray and Group C was control group and only treated with steam inhalation. Efficacy of the treatment was assessed in the terms of Total Rhinitis Symptom Complex (TSC) scores and individual symptom score which was calculated on the basis of Okuda's grading system. Base line total symptom complex (TSC) scores were reduced in group A and group B by 84.0% after 4 week treatment whereas in group C it was reduced by only 38.0%. Decrease in mean score for sneezing was 95.0% in group A and group B whereas it was only 28.3% in group C. Similarly decrease in mean score for rhinorrhoea in azelastine group was 94.4% and in beclomethasone group was 95.3% in comparison to steam inhalation group where it was 25.0%. Only the beclomethasone reduced nasal stuffiness score significantly by 95.0%. No significant adverse effects of the drugs were observed. The present study establishes the relative efficacy and tolerability ofazelastine nasal spray as compared to beclomethasone nasal spray in symptomatic patients of allergic rhinitis.

    Leukotriene (LT) C(4), a potent chemical mediator in human bronchial asthma, is metabolized to less active LTE(4) via LTD(4) in 2 consecutive enzymatic reactions by gamma-glutamyl transpeptidases and dipeptidases. We examined whether this inactivation process of LTC(4) was affected by fluticasone propionate, beclomethasone dipropionate, disodium cromoglycate, and salbutamol sulfate in transformed human bronchial epithelial cells. Fluticasone propionate and beclomethasone dipropionate accelerated LTC(4) catabolism by inducing activity of a LTC(4)-degrading enzyme, gamma-glutamyl transpeptidase-related enzyme (gamma-GTPRE), in transformed human bronchial epithelial cells. The activation of gamma-GTPRE might be regulated transcriptionally. This is a novel regulatory mechanism by which glucocorticosteroids exert antiasthma activities.

    The aim of this work was to evaluate the in vitro performance of nebulized nanosuspension formulation when nebulized using ultrasonic nebulizer. The present investigation deals with successful formulation of Beclomethasone dipropionate loaded HPMCP nanospheres prepared by solvent evaporation technique using PEG 400 as a stabilizer. Beclomethasone dipropionate is a water insoluble drug molecule was encapsulated in HPMCP nanospheres to have pH dependent solubility at basic pH for targeted drug delivery in lung and studied for in vitro cytotoxicity and immediate release capability. The synthesized nanospheres were characterized through drug excipient compatibility, surface topography; mean particle size , zeta potential, PDI, entrapment efficiency and drug loading, in vitro diffusion, aerodynamic, in vitro cytotoxicity and stability studies. The mean particle size and PDI of the optimized batch (F1) had 197.6±0.40 nm and 0.324 ±0.35, respectively. The % entrapment efficiency and % drug loading was found to be 86.56±1.32 and 8.30±0.27, respectively. The optimized batch F1 showed % cumulative drug release 94.77±0.24 at 1 h. The formulation showed cell viability up to 91.28%. It can be concluded that, Beclomethasone dipropionate loaded HPMCP nanospheres was found to be safe, stable with significant increase in solubility and bypass the liver. © Georg Thieme Verlag KG Stuttgart · New York.

    2018-01-01

    To verify the effect of a new nasal spray made from natural medicines on allergic rhinitis in animals. Methods: The main natural medicines contained in Acusine nasal spray plus essential traditional Chinese medicine contained in drugs for allergic rhinitis in Chinese market were used. By preparation process of extraction of traditional Chinese medicine such as steam distillation, ethanol extraction, a new nasal spray made from natural medicines was prepared. In the meantime, 24 BALB/c mice and New Zealand white rabbits were used. Then, mice were randomly divided into four group; control group, beclomethasone dipropionate group, Acusine group and new spray group, 6 mice in each group. Moreover, the effect of the new nasal spray made on passive cutaneous anaphylaxis was conducted by detecting absorptions of Evan’s blue (620nm) in the four groups. Allergic rhinitis models in 40 New Zealand white rabbits were established. Consequently, 40 allergic rhinitis models in rabbits were randomly divided into control group, Acusine group and new spray group, 10 rabbits in each group. The four groups were sprayed nasally with saline, Acusine spray and new spray respectively, three times/d, for 30 days. The nasal resistances in the four groups were measured with a rhinoresistometer. Moreover, their nasal mucosa was taken for HE staining. Consequently, their pathological manifestations were observed. The results: Absorption of Evan’s blue (620nm) of new spray group will be found significantly lower than Acusine group (P0.05). On the other hand, absorption of Evan’s blue (620nm) of beclomethasone dipropionate group will be significantly lower than Acusine group (Ptreatment effect on allergic rhinitis, similar with beclomethasone dipropionate, than Acusine Nasal Spray but also will not leave side effect on nasal mucosa, compared with beclomethasone dipropionate. Thus, the new spray made from natural medicines can be further studied as a better prescription drug, rather than an

    The in-vitro aerosol performance of two combination dry powder inhaler (DPI) products, Foster ® NEXThaler ® and Seretide ® Diskus ® were investigated with single particle aerosol mass spectrometry (SPAMS). The in-vitro pharmaceutical performance is markedly different for both inhalers. Foster ® NEXThaler ® generates a higher fine particle fraction (FPF aerodynamic particle size distribution (APSD), it could be verified with SPAMS that overall Foster ® NEXThaler ® emits a significantly higher number of fine and extra fine particles with a median aerodynamic diameter (MAD) of 2.1 μm while Seretide ® Diskus ® had a larger MAD of 3.1 μm. Additionally, the interactions between the two active pharmaceutical ingredients (APIs) in both products are different. While Seretide ® Diskus ® emits a significant (37%) number of co-associated API particles, only a negligible number of co-associated API particles were found in Foster ® NEXThaler ® (<1%). A major difference with Foster ® NEXThaler ® is that it contains magnesium stearate (MgSt) as a second excipient besides lactose in a so-called 'dual excipient' platform. The data generated using SPAMS suggested that nearly all of the beclomethasone dipropionate particles in Foster ® NEXThaler ® also contain MgSt and must therefore be co-associated with this additional excipient. This may help explain why beclomethasone dipropionate in Foster ® NEXThaler ® forms less particle co-associations with the second API, formoterol fumarate, shows a lower cohesive strength in respect to beclomethasone itself and why both APIs exhibit superior detachment from the carrier as evidenced by the increased eFPF and smaller MAD.

    Asthma is under-diagnosed in many parts of the world. We aimed to assess the outcome of a capacitating program on asthma for non-specialist physicians and other healthcare professionals working in the public system in Ribeirão Preto, Brazil. A group of 16 asthma specialists developed a one-year capacitating program in 11 healthcare clinics in the Northern District of the city, which included lectures on asthma, training on inhalation device use and spirometry, and development of an asthma management protocol. Researchers visited one health unit 2-4 times monthly, working with doctors on patients' care, discussing cases, and delivering lectures. Asthma education was also directed to the general population, focusing on recognition of signs and symptoms and long-term treatment, including production of educational videos available on YouTube. Outcome measures were the records of doctors' prescriptions of individual asthma medications pre- and post-intervention. Prior to the program, 3205 units of inhaled albuterol and 2876 units of inhaled beclomethasone were delivered by the Northern District pharmacy. After the one-year program, there was increase to 4850 units (51.3%) for inhaled albuterol and 3526 units (22.6%) for inhaled beclomethasone. The albuterol increase followed the recommendation given to the non-specialist doctors by the asthma experts, that every patient with asthma should have inhaled albuterol as a rescue medication, by protocol. No increase was observed in other districts where no capacitating program was conducted. A systematic capacitating program was successful in changing asthma prescription profiles among non-specialist doctors, with increased delivery of inhaled albuterol and beclomethasone.

    The effect of three amino acid coatings (L-leucine, L-valine and L-phenylalanine) on particle integrity, aerosolization properties, cellular interaction, cytocompatibility, and drug permeation properties of drug combination powder particles (beclomethasone dipropionate and salbutamol sulphate) for dry powder inhalation (DPI) was investigated. Particles with crystalline L-leucine coating resulted in intact separated particles, with crystalline L-valine coating in slightly sintered particles and with amorphous L-phenylalanine coating in strongly fused particles. The permeation of beclomethasone dipropionate across a Calu-3 differentiated cell monolayer was increased when compared with its physical mixture. Drug crystal formation was also observed on the Calu-3 cell monolayer. The L-leucine coated particles were further investigated for cytocompatibility in three human pulmonary (Calu-3, A549 and BEAS-2B) and one human macrophage (THP-1) cell lines, where they showed excellent tolerability. The l-leucine coated particles were also examined for their ability to elicit reactive oxygen species in pulmonary BEAS-2B and macrophage THP-1 cell lines. The study showed the influence of the amino acid coatings for particle formation and performance and their feasibility for combination therapy for pulmonary delivery. Copyright © 2016 Elsevier B.V.

    Full Text Available Acute obstructive laryngitis (croup — J.05 is one of the pressing and insufficiently studied issues in pediatrics. Over recent years focus has been on the issues related to the treatment of this condition due to a relative incidence rate and severity of croup in children of minor age. A clinical and lab study has been undertaken to identify the etiological structure and evaluation of beclo methasone efficiency in 163 children aged 3 months to 5 years with croup. Results of the study have demonstrated that most often the etiological factor of croup is parainfluenza virus (56,1% of all cases, respiratory syncytial virus is revealed in 44,73% of all cases. Bacterial etiology of the disease have been found in 12,5% of children with the etiological agent being Haemophilus influenzae type b. Supplementation of the treatment for acute obstructive laryngitis of virus etiology with inhalant beclomethasone makes it possible to reduce the number of intubations, hence decrease the frequency of complications after invasive interventions and cut the length of hospital stay.Key words: Beclomethasone, acute obstructive laryngitis, children.

    Adrenocortical suppression is a well-known risk of systemic steroids, but is thought less likely to occur with topical intranasal corticosteroids. However, the UK Committee on the Safety of Medicines (UKCSM) has expressed concern about the possibility of this complication. We assessed the prevalence of adrenal suppression in patients with rhinitis using intranasal beclomethasone and betamethasone; and the potential value of salivary cortisol as a tool for detecting this complication. Sixty-six patients (38 men: 28 women; mean age 49.6[SD 16.0] years) were prospectively screened for adrenal insufficiency using clinical assessment and salivary cortisol measurements. Abnormalities at this initial screening were confirmed with a Short Synacthen Test (SST). No patient was clinically Cushingoid. All 22 beclomethasone users had normal salivary cortisols. Eleven (25%) of 44 patients using betamethasone had subnormal salivary cortisol levels (mean morning cortisol 2.8[SD 0.9]nmol/l) suggesting adrenal suppression, which was confirmed by an impaired SST in each case. The positive predictive value of salivary cortisol measurements was 100%. Only patients with abnormal salivary cortisols had a SST, so no comment can be made about sensitivity/specificity. Topical betamethasone may produce occult adrenal insufficiency and assessment of adrenal function is recommended in these patients. Measurement of salivary cortisol is a useful, non-invasive and economical test for monitoring patients using intranasal corticosteroids.

    The purpose of this article is to provide a systematic overview of the literature on adrenal suppression and Cushing's syndrome secondary to an interaction between inhaled/intranasal fluticasone and ritonavir. The clinical presentation, diagnosis and management will be discussed. A literature search using Medline and EMBASE and a search of abstracts of the three previous years of major HIV-related conferences were carried out. There were 25 cases (15 adult and 10 paediatric) of significant adrenal suppression secondary to an interaction between ritonavir and inhaled fluticasone, and three cases involving ritonavir and intranasal fluticasone. Cases with other steroids were not reported; however, there were cases of adrenal suppression with itraconazole [also a potent cytochrome p (CYP) 3A4 inhibitor] and inhaled budesonide. Clinicians need to differentiate between antiretroviral-induced lipodystrophy syndrome and iatrogenic Cushing's syndrome secondary to glucocorticoid use. Long-term fluticasone and ritonavir should be avoided. If ritonavir is required, another inhaled steroid such as low-dose budesonide or beclomethasone can be used cautiously. Upon discontinuation of inhaled corticosteroids, close monitoring for symptoms of adrenal insufficiency is warranted. The need for steroid replacement therapy at physiological doses should be assessed. The combination of ritonavir and fluticasone should be avoided. Budesonide, beclomethasone, triamcinolone and flunisolide appear to be safer options.

    Full Text Available The most frequent symptoms of chronic rhinitis are nasal pruritus, sneezing, nasal secretion and nasal obstruction. The aim of our research was to determine the effect of the local corticosteroid upon nasal symptoms of the patients with moderate season and perennial hypersensitive rhinitis.In its character the study was prospective and controlled. The total number of 55 patients with moderate hypersensitive rhinitis was examined; 36 of them were treated by the local corticosteroid while 18 were with no therapy at all. The patients were treated with beclomethasone dipropionate in the nasal spray (daily dose of 400 p.g for 6 weeks. All the patients were subdued to many otorhinolaryngological examinations: before the therapy (basal, after a week's therapy and after six-week therapy. The nasal symptoms were graded according to their intensity and then their overall score was compared.After a week's therapy the results show a very important reduction of the score of the symptoms in the patients of the treated subgroups with respect to the basal state while after six week therapy no further important change was determined. In the patients of the non-treated subgroups there was no significant change of the symptom score during the follow-up period.The local treatment with beclomethasone dipropionate represents an important medicament of the first therapeutic line in moderate season and perennial hypersensitive rhinitis.

    1978-10-01

    A simulated respiratory system was developed for the in vitro evaluation of two differently designed oral inhalation delivery systems. The deposition properties of a newly designed delivery system used for triamcinolone acetonide were compared to the more conventional, commercially available adapter utilized for an aerosol containing beclomethasone dipropionate. The simulated respiratory system was constructed so that the delivered dose of active ingredient could be classified into two fractions: the fraction that would be deposited in the oral cavity and throat and the fraction that would reach the desired site of activity in the respiratory tract. Based on this method, the newly designed system delivered more than 95% of the labeled dose to the desired site. The beclomethasone dipropionate aerosol system, which was observed to discharge the active ingredient with a greater intensity, delivered approximately 40% of the labeled dose. The particle-size distribution of the dose dispensed from the newly designed delivery system attached to the triamcinolone acetonide aerosol was determined using an impactor technique. No effort was made to correlate these results with an in vivo response.

    2012-01-01

    There is concern that P-glycoprotein mediated efflux contributes to steroid resistance. Therefore, this study examined bidirectional corticosteroid transport and induction capabilities for P-glycoprotein (P-gp) to understand which of the systemic and inhaled corticosteroids interacted with P-gp to the greatest extent. Hydrocortisone, prednisolone, prednisone, methylprednisolone, and dexamethasone represented systemically active drugs, while fluticasone propionate, beclomethasone dipropionate, ciclesonide and budesonide represented inhaled corticosteroids. Aldosterone and fludrocortisone represented mineralocorticoids. All drugs were detected using individually optimised HPLC protocols. Transport studies were conducted through Caco-2 monolayers. Hydrocortisone and aldosterone had efflux ratios below 1.5, while prednisone showed a P-gp mediated efflux ratio of only 1.8 compared to its active drug, prednisolone, with an efflux ratio of 4.5. Dexamethasone and beclomethasone had efflux ratios of 2.1 and 3.3 respectively, while this increased to 5.1 for methylprednisolone. Fluticasone showed an efflux ratio of 2.3. Protein expression studies suggested that all of the inhaled corticosteroids were able to induce P-gp expression, from 1.6 to 2 times control levels. Most of the systemic corticosteroids had higher passive permeability (> 20 × 10 −6 cm/s) compared to the inhaled corticosteroids (> 5 × 10 −6 cm/s), except for budesonide, with permeability similar to the systemic corticosteroids. Inhaled corticosteroids are not transported by P-gp to the same extent as systemic corticosteroids. However, they are able to induce P-gp production. Thus, inhaled corticosteroids may have greater interactions with other P-gp substrates, but P-gp itself is less likely to influence resistance to the drugs. -- Highlights: ► Inhaled corticosteroids are only weak substrates for P-gp, including budesonide. ► Inhaled corticosteroid potent P-gp inducers especially fluticasone and

Hydrofluoralkane showed to be a safe propellent, with pulmonary deposition ranging from 50 to 60%, and to have significant efficacy, when compared with placebo (p < 0.003 in controlled clinical trials. Most works using hydrofluoralkane included beclomethasone diproprionate. Approximate annual cost of a treatment with beclomethasone diproprionate/hydrofluoralkane was lower than with beclomethasone diproprionate/clorofluorcarbon. Some studies assessed salbutamol, fluticasone, flunisolide and the association fluticasone-salmeterol, with hydrofluoralkane as propellent in pressurized metered-dose inhalers. CONCLUSIONS: Efficacy and safety of hydrofluoralkane as propellent of bronchodilators and inhaled corticosteroids in adults was evidenced

    The metabolic syndrome is associated with increased risk for both diabetes and coronary artery disease, which insulin resistance alone does not satisfactorily explain. We propose an additional and complementary underlying mechanism of glucocorticoid resistance. Using acanthosis nigricans (AN) and skin vasoconstrictor (SVC) response to topically applied beclomethasone dipropionate as markers of insulin and glucocorticoid resistance, respectively, we compared anthropometric, biochemical, pro-inflammatory markers and the SVC response in subjects with AN in two studies: STUDY 1 was used to compare subjects with AN (Grade 4, n = 32), with those without AN (n = 68) while STUDY 2 compared these responses among a cross-section of diabetic patients (n = 109) with varying grades of AN (grade 0, n = 30; grade 1, n = 24; grade 2, n = 18; grade 3, n = 25; grade 4, n = 12). In both studies there was an inverse relationship between AN Grade 4 and the SVC response, (P glucocorticoid action in vascular tissue.

    Current guidelines recommend the use of inhaled corticosteroids (ICS) for suppression of airway inflammation in patients with asthma. Although it is well known that ICS cause dose-related adrenocortical suppression, it is less known that they can lead to iatrogenic Cushing's syndrome (CS). Fluticasone propionate (FP) is an ICS more potent than beclomethasone and budesonide. FP is metabolized as mediated by cytochrome P450 3A4 in the liver and the gut. Systemic bioactivity of FP can increase with the use of drugs that affect the cytochrome P450. Herein, we report the rapid development of iatrogenic CS in a patient receiving paroxetine and mirtazepine for 12 weeks in addition to inhaled FP.

    We have previously described iatrogenic Cushing's syndrome secondary to intranasal steroids. This report further highlights the potential deleterious effects of intranasal steroids. Nine cases (including the original two cases) are reviewed to show the varied clinical manifestations of adrenal suppression caused by intranasal steroids. Four presented with Cushing's syndrome, three with growth failure, while two asymptomatic patients were discovered in the course of pituitary function testing. Four children had dysmorphic syndromes--Down's, Treacher-Collins, CHARGE association, and campomelic dysplasia--reflecting the vulnerability of such children to ENT problems, together with the difficulty of interpreting steroid induced growth failure in this context. Adrenal suppression was seen not only with betamethasone but also with budesonide, beclomethasone and flunisolide nasal preparations. A careful enquiry as to the use of intranasal steroids should be routine in children presenting with unexplained growth failure or Cushing's syndrome. Particular vigilance/awareness is required in children with dysmorphic syndromes.

    Even though there are multiple options for the treatment of asthma, there still exists a fair group of patients with difficult-to-control asthma. We describe for the first time the real-world effects of three-year omalizumab treatment on patients with difficult-to-control asthma, seen in a social security hospital in a Latin American country. Difficult-to-control asthmatic patients from the out-patient clinic of a regional hospital were recruited to receive a three-year omalizumab course. Efficacy parameters were asthma control test (ACT) score; FEV1; daily beclomethasone maintenance dose; and unplanned visits for asthma exacerbations (emergency room (ER), hospitalisations, intensive care). 52 patients were recruited, 47 completed the three-year treatment (42 female, 15-67 years, mean age 43.5). Comparing efficacy parameters of the year before omalizumab with the 3rd year of omalizumab: mean ACT improved from 12.4 to 20.5, mean FEV1 from 66.3% (standard deviation (SD) 19.1%) to 88.4% (SD 16.2%) of predicted, while mean beclomethasone dose reduced from 1750 to 766 mcg/day and there was a significant reduction in patients experiencing ER visits (from 95% to 19%, pomalizumab, two because of an adverse event (anaphylaxis, severe headache, both resolved without sequelae). Omalizumab improved most clinical parameters of Mexican patients with difficult-to-control asthma. Especially the rates of ER visits and hospitalisation were significantly reduced, thus reducing costs. Omalizumab was generally well tolerated. Copyright © 2013 SEICAP. Published by Elsevier Espana.

    Inhaled corticosteroids used for treating persistent asthma can suppress adrenal cortisol secretion. This inhibition of endogenous cortisol secretion is an important marker of systemic steroid activity. Although meta-analyses have demonstrated a dose-dependent suppression of cortisol by inhaled corticosteroids, regardless of inhaler type, the impact of novel freon-free inhaled corticosteroid preparations has not been reviewed. The aim of this study was to synthesize all currently available studies on novel inhaled corticosteroid preparations, including ciclesonide, beclomethasone dipropionate, budesonide, and fluticasone propionate. In particular, we aimed to compare the effect of ciclesonide on cortisol suppression with other existing preparations. We carried out a systematic review of the medical data bases on cortisol suppression in patients due to inhaled corticosteroids. A multivariate regression model was used to determine dose-dependent relationships between each inhaled corticosteroid and cortisol suppression with respect to age, type of inhaler, and study design. From analysis of 64 studies identified in the review, the strongest dose-response urinary cortisol suppression was observed in patients treated with beclomethasone (8.4% per 100 μg; p = 0.029), followed by fluticasone (3.2% per 100 μg; p < 0.001), and budesonide (3.1% per 100 μg; p = 0.001). No significant urinary cortisol suppression was associated with ciclesonide treatment (1.8% per 100 μg; p = 0.267). Although ciclesonide did not affect cortisol levels, this appeared to be due to its unique pharmacokinetic properties rather than the use of a novel formulation. Our findings indicated that the introduction of novel freon-free delivery technologies for inhaled corticosteroids had not eliminated adverse adrenal suppression of cortisol secretion.

    Full Text Available Hypersensitive rhinitis coupled with nasal polyposis is always followed by the following symptoms, namely, nasal pruritus, sneezing, nasal secretion and nasal obstruction. The aim of our research was to determine the local corticosteroid effect upon the mentioned symptoms of the patients suffering from hypersensitive rhinitis coupled with bilateral moderate nasal polyposis.The research was prospective and controlled. There was a total od 13 examined patients suffering from hypersensitive rhinitis coupled with bilateral moderate nasal polyposis; out of this number 10 patients were subjected to local corticosteroid therapy while in 3 patients no therapy was applied whatsoever. The therapy consisted of beclomethasone dipropionate treatment in water nasal spray. The daily dose was 400 micrograms; it was continually delivered in 6 months. The patients of both the groups were controlled by a series of otorhinolaryngological examinations: before the therapy (basal, after six-week therapy, after three-month therapy and after six-month therapy. The followed nasal symptoms are graded regarding their intensity while their average score was intra group and inter-group compared.In the group of the treated ones the research results after six-week therapy show a considerable reduction of the average symptom score with respect to the basal state. Further treatment, that is, after three-month and six-month therapy, did not show any considerable change. In the non-treated group during the follow-up period the average symptom score did not considerably change.To conclude it can be said that the local beclomethasone dipropionate therapy represents an important medicament, of the first therapy rank with hypersensitive rhinitis compled with hilateral moderate nasal polyposis

A large body of evidence has demonstrated the importance of small airways as a pharmacological target in these clinical conditions. Despite a deeper understanding of the pathophysiological mechanisms, the epidemiological observations show that a significant proportion of asthmatic and COPD patients have a suboptimal (or lack of control of their diseases. Different factors could influence the effectiveness of inhaled treatment in chronic respiratory diseases: patient-related (eg, aging; disease-related (eg, comorbid conditions; and drug-related/formulation-related factors. The presence of multiple illnesses is common in the elderly patient as a result of two processes: the association between age and incidence of degenerative diseases; and the development over time of complications of the existing diseases. In addition, specific comorbidities may contribute to impair the ability to use inhalers, such as devices for efficient drug delivery in the respiratory system. The inability to reach and treat the peripheral airways may contribute to the lack of efficacy of inhaled treatments. The recent development of inhaled extrafine formulations allows a more uniform distribution of the inhaled treatment throughout the respiratory tree to include the peripheral airways. The beclomethasone/formoterol extrafine formulation is available for the treatment of asthma and COPD. Different biomarkers of peripheral airways are improved by beclomethasone

    Little is known about trends in morbidity and/or mortality due to asthma in Latin America. To examine trends in hospitalizations and mortality due to asthma from 1997-2000 to 2011 in Costa Rica. The rates of hospitalization due to asthma were calculated for each sex in 3 age groups from 1997 to 2011. The number of deaths due to asthma was first calculated for all groups and then for each sex in 3 age groups from 2000 to 2011. All analyses were conducted over the entire period and separately for the periods before and after a National Asthma Program (NAP) in 2003. Data also were available for prescriptions for beclomethasone since 2004. All analyses were conducted by using Epi Info. Substantial reductions were found in hospitalizations and deaths due to asthma in Costa Ricans (eg, from 25 deaths in 2000 to 5 deaths in 2011). Although, the percentage decrement in the rates of hospitalization for asthma in subjects Costa Rica, there was a marked decrement in hospitalizations and mortality due to asthma from 1997-2000 to 2011. In younger subjects, this is likely due to guidelines that, since 1988, recommend inhaled corticosteroids for persistent asthma. In older adults, the NAP probably enhanced reductions in hospitalizations and deaths due to asthma through inhaled corticosteroid use.

    1992-10-16

    A 26-year-old man, practicing for a variety performance as "fire-eater", accidentally inhaled and ingested about 10 ml petroleum. Soon afterwards he developed dyspnoea, an urge to cough, fever up to 39 degrees C and loss of retentiveness. He was treated as an out-patient with doxycycline, 100 mg daily, and aspirin, 500 mg three times daily. While this reduced the dyspnoea, the elevated temperature persisted and he had haemoptysis. Chest x-ray and computed tomography 12 days after the aspiration revealed areas of atelectasis and of liquefaction necroses. Bronchoscopic and cytological examinations showed eosinophilic alveolitis and mucosal necrosis in both main bronchi. The symptoms were improved by two inhalations of beclomethasone four times daily, and systemic treatment with prednisolone, 50 mg daily, together with parenteral antibiotic administration (cefotaxime, 1.0 g twice daily). The focal lung lesions regressed completely within a few weeks. Five months after the aspiration computed tomography merely demonstrated discrete scarring of the previously necrotic lesions. This case illustrates that, even with extensive necrotic lung changes after petroleum aspiration, conservative treatment is justified and likely to be effective.

  1. Dispersibility of lactose fines as compared to API in dry powders for inhalation.

    This work investigates the dispersion performance of fine lactose particles as function of processing time, and compares it to the API, using Beclomethasone Dipropionate (BDP) as model API. The total load of fine particles is kept constant in the formulations while the proportions of API and lactose fines are varied. Fine particle assessment demonstrates that the lactose fines have higher dispersibility than the API. For standard formulations, processing time has a limited effect on the Fine Particle Fraction (FPF). For formulations containing magnesium stearate (MgSt), FPF of BDP is heavily influenced by processing time, with an initial increase, followed by a decrease at longer mixing times. An equation modeling the observed behavior is presented. Surprisingly, the dispersibility of the lactose fines present in the same formulation remains unaffected by mixing time. Magnesium analysis demonstrates that MgSt is transferred to the fine particles during the mixing process, thus lubrication both BDP and lactose fines, which leads to an increased FPF. Dry particle sizing of the formulations reveals a loss of fine particles at longer mixing times. Incorporation of fine particles into the carrier surfaces is believed to be behind this, and is hence a mechanism of importance as regards the dispersion performance of dry powders for inhalation.

    To characterise a biorelevant simulated lung fluid (SLF) based on the composition of human respiratory tract lining fluid. SLF was compared to other media which have been utilized as lung fluid simulants in terms of fluid structure, biocompatibility and performance in inhalation biopharmaceutical assays. The structure of SLF was investigated using cryo-transmission electron microscopy, photon correlation spectroscopy and Langmuir isotherms. Biocompatibility with A549 alveolar epithelial cells was determined by MTT assay, morphometric observations and transcriptomic analysis. Biopharmaceutical applicability was evaluated by measuring the solubility and dissolution of beclomethasone dipropionate (BDP) and fluticasone propionate (FP), in SLF. SLF exhibited a colloidal structure, possessing vesicles similar in nature to those found in lung fluid extracts. No adverse effect on A549 cells was apparent after exposure to the SLF for 24 h, although some metabolic changes were identified consistent with the change of culture medium to a more lung-like composition. The solubility and dissolution of BDP and FP in SLF were enhanced compared to Gamble's solution. The SLF reported herein constitutes a biorelevant synthetic simulant which is suitable to study biopharmaceutical properties of inhalation medicines such as those being proposed for an inhaled biopharmaceutics classification system.

    In this article, we present a novel, scalable liposomal preparation technique suitable for the entrapment of pharmaceutical agents into liposomes. This new method is based on the ethanol-injection technique and uses a membrane contactor module, specifically designed for colloidal system preparation. In order to investigate the process, the influence of key parameters on liposome characteristics was studied. It has been established that vesicle-size distribution decreased with a decrease of the organic-phase pressure, an increase of the aqueous-phase flow rate, and a decrease of the phospholipid concentration. Additionally, special attention was paid on reproducibility and long-term stability of lipid vesicles, confirming the robustness of the membrane contactor-based technique. On the other hand, drug-loaded liposomes were prepared and filled with two hydrophobic drug models. High entrapment-efficiency values were successfully achieved for indomethacin (63%) and beclomethasone dipropionate (98%). Transmission electron microscopy images revealed nanometric quasispherical-shaped multilamellar vesicles (size ranging from 50 to 160 nm).

    To quantify use of high dose inhaled corticosteroids (ICS) and add-on therapy in adults, and children aged 12 and over, in the community. Cross-sectional observational survey of UK general practice prescribing records from July 2002 to June 2003 utilising the Doctors Independent Network clinical database. 30,895 patients aged 12 and over were treated for asthma with inhaled corticosteroids, with a quantifiable daily dose recommendation in 22,027 cases. Twenty-seven percent (95% Confidence Intervals 26-28%) were prescribed 'high-dose' ICS (>800 mcg/day beclomethasone or equivalent). Of these, 32% (31-33%) were not currently prescribed add-on therapy (long acting B2 agonists, leukotriene antagonists, theophylines), and most of these (84%, 82-86%) had never received a prior trial of add-on therapy. High dose ICS therapy was commonly prescribed to people with asthma, frequently without co-prescribed add-on therapy. Many adults with more severe asthma may be receiving treatment that does not accord with current evidence of best practice.

    The Interagency Emergency Health Kit (IEHK) provides a standard package of medicines and simple medical devices for aid agencies to use in emergencies such as disasters and armed conflicts. Despite the increasing burden of non-communicable diseases (NCDs) in such settings, the IEHK includes few drugs and devices for management of NCDs. Using published data to model the population burden of acute and chronic presentations of NCDs in emergency-prone regions, we estimated the quantity of medications and devices that should be included in the IEHK. NCDs considered were cardiovascular diseases, diabetes, hypertension and chronic respiratory disease. In scenario 1 (the primary scenario), we assumed that resources in the IEHK would only include those needed to manage acute life-threatening conditions. In scenario 2, we included resources required to manage both acute and chronic presentations of NCDs. Drugs and devices that might be required included amlodipine, aspirin, atenolol, beclomethasone, dextrose 50%, enalapril, furosemide, glibenclamide, glyceryl trinitrate, heparin, hydralazine, hydrochlorothiazide, insulin, metformin, prednisone, salbutamol and simvastatin. For scenario 1, the number of units required ranged from 12 (phials of hydralazine) to ∼15 000 (tablets of enalapril). Space and weight requirements were modest and total cost for all drugs and devices was approximately US$2078. As expected, resources required for scenario 2 were much greater. Space and cost requirements increased proportionately: estimated total cost of scenario 2 was $22 208. The resources required to treat acute NCD presentations appear modest, and their inclusion in the IEHK seems feasible.

    The objective of this study was to further evaluate the need for a vertical inlet extension when testing solution metered dose inhalers using the TSI Model 3306 Impactor Inlet in conjunction with the TSI Model 3320 Aerodynamic Particle Sizer (APS). The configurations tested using the TSI system were compared to baseline measurements that were performed using the Andersen Mark II 8-stage cascade impactor (ACI). Seven pressurized solution metered dose inhalers were tested using varied concentrations of beclomethasone dipropionate (BDP), ethanol, and HFA 227 propellant. The inhalers were tested with the cascade impactor, and with the TSI system. The TSI system had three different configurations as the manufacturer provided (0 cm) or with inlet extensions of 20 and 40 cm. The extensions were located between the USP inlet and the Model 3306 Impactor Inlet. There were no practical differences between each system for the stem, actuator, or USP inlet. The fine particle mass (aerodynamic mass TSI system in order to give mass results that correlate to the ACI, especially for formulations having significant concentrations of low volatility excipients. Additionally, the results generated from this study were used to evaluate the product performance of HFA 227 based solution formulations that contain varying concentrations of ethanol as a cosolvent.

    Azelastine hydrochloride is a nasally administered antihistamine that is effective and safe for the treatment of perennial and seasonal allergic rhinitis. In addition to acting as a histamine H1-receptor antagonist, azelastine also inhibits the production or release of many chemical mediators of the allergic response such as leukotrienes, free radicals, and cytokines. After nasal administration, azelastine is systemically absorbed with a bioavailability of about 40%. The side effects of azelastine are drowsiness, headache, and bitter taste. Azelastine has a rapid onset of action with a benefit in about 2 hours and a prolonged duration of activity (12 to 24 hours). Studies have shown azelastine to be more effective than placebo in terms of reduction of the major and total symptom complexes of allergic rhinitis. Comparison studies have demonstrated that azelastine is as effective as ebastine, loratadine, cetirizine hydrochloride, and terfenadine at symptom reduction, with varying results when compared with the corticosteroids budesonide and beclomethasone. Although there are conflicting studies, some have demonstrated that azelastine reduces the nasal congestion of allergic rhinitis. This feature that distinguishes it from oral antihistamines is of great interest because corticosteroids are known to be quite effective for the relief of nasal congestion, whereas the antihistamines are effective for the sneezing, itchy eyes, itchy nose, and watery eyes, but not the congestion. Azelastine nasal spray seems to be an efficacious treatment for allergic rhinitis with a rapid onset and long duration of activity, but without the systemic adverse effects of traditional sedating antihistamines.

    Full Text Available BACKGROUND The eye is especially susceptible to the symptoms of allergic rhinitis, itching (pruritus, tearing (epiphora and redness (erythema because it lacks a mechanical barrier that could prevent the deposition of allergens, such as pollen on the conjunctival surface. These ocular symptoms have been described as examples of the type 1 immediate hypersensitivity reaction. A number of recently published clinical studies apparently support the positive effect of intranasal steroidal sprays on ocular allergy symptoms. The aim of the study is to evaluate the role of intranasal steroids in relieving ocular symptoms in allergic rhinitis. MATERIALS AND METHODS 60 subjects who had seasonal allergic rhinitis with ocular symptoms came to Outpatient Department of Chalmeda Anand Rao Hospital in the year 2015-2016. Randomly, each intranasal steroid is given to 12 patients to a total of 60 patients for 4 weeks 2 puffs in each nostril twice daily and the clinical response is observed. RESULTS A subjective improvement in ocular symptoms was observed in 11 of the 12 patients treated with fluticasone furoate, 8 of 12 patients with fluticasone propionate, 7 of the 12 patients with mometasone furoate, 6 of the 12 patients with beclomethasone and 6 of the 12 patients with budesonide. CONCLUSION Intranasal corticosteroids, which are used for seasonal allergic rhinitis with ocular symptoms are effective in controlling of ocular symptoms. Among these, intranasal corticosteroids, which are used for allergic rhinitis, fluticasone furoate is more effective in relieving ocular symptoms in our study.

    Background Until 1994, assistance provided by the Municipal Public Health System to children with asthma in Belo Horizonte, Brazil, was ineffective because it focused only on treating exacerbations. This scenario motivated the implementation of the Wheezy Child Program. Objectives The main objectives were to reduce emergency room visits and hospitalizations. Methods The strategies adopted were as follows: continued medical education for pediatricians, reorganization of public assistance into different levels of complexity regarding asthma care, and free dispensation of inhaled beclomethasone, albuterol, and valved spacers. A partnership between the Pediatric Pulmonology staff of the Federal University of Minas Gerais and the Belo Horizonte Municipal Health Authority made these strategies come to fruition, especially through the training of health workers and the devising of protocol after GINA guidelines. Results Of 2149 patients with a history of hospitalization after program admission, only 453 were re-admitted in the 6 to 12 months after, a reduction of 79%. There was a 300% increase in the use of aerosol and a reduction to 50% in the use of oxygen-driven nebulizers (P rate was 50%. Conclusions The Wheezy Child Program has significantly reduced hospitalizations and emergency room visits, has improved quality of life, and has shown that programs of this kind are feasible in low- to middle-income countries. More than 30,000 children have been assisted by the program, and now it seeks to optimize asthma control and increase adherence rates. PMID:23282315

    The Adverse Outcome Pathway (AOP) framework represents a valuable conceptual tool to systematically integrate existing toxicological knowledge from a mechanistic perspective to facilitate predictions of chemical-induced effects across species. However, its application for decision-making requires the transition from qualitative to quantitative AOP (qAOP). Here we used a fish model and the synthetic glucocorticoid beclomethasone dipropionate (BDP) to investigate the role of chemical-specific properties, pharmacokinetics, and internal exposure dynamics in the development of qAOPs. We generated a qAOP network based on drug plasma concentrations and focused on immunodepression, skin androgenisation, disruption of gluconeogenesis and reproductive performance. We showed that internal exposure dynamics and chemical-specific properties influence the development of qAOPs and their predictive power. Comparing the effects of two different glucocorticoids, we highlight how relatively similar in vitro hazard-based indicators can lead to different in vivo risk. This discrepancy can be predicted by their different uptake potential, pharmacokinetic (PK) and pharmacodynamic (PD) profiles. We recommend that the development phase of qAOPs should include the application of species-species uptake and physiologically-based PK/PD models. This integration will significantly enhance the predictive power, enabling a more accurate assessment of the risk and the reliable transferability of qAOPs across chemicals.

    Exogenous pulmonary surfactant (EPS) could be used as carrier of glucocorticoids (GCs) in therapy for respiratory diseases. We formulated novel combination drug products containing bovine EPS and one GC (10wt%): beclomethasone (Be), budesonide (Bu) or fluticasone (Flu), and studied the GCs action on the surface activity and biophysical properties of EPS. Subtype ratio was evaluated by phospholipid determination; surface tension (ST) with a pulsating bubble surfactometer and conformational changes by Electron Spin Resonance (ESR). GCs were incorporated into EPS in more than 80%. None of them generated disaggregation of surfactant, only Bu was found in the light subtype. Bu and Be caused minimal changes in fluidity on polar region of bilayers, but these changes were not enough to inactivate the surfactant. Flu did not significantly alter any biophysical properties or surface activity. These novel combination EPS-GC products might be a promising strategy in the therapy of pulmonary diseases as the incorporation of the GCs tested did not cause detrimental effects on EPS functionality.

    This paper presents a gas chromatography-mass spectrometry (GC-MS) study carried out on human urine to verify whether the administration of glucocorticoids can affect the urinary steroid profile, and especially the levels of endogenous glucocorticoids, androgens and their main metabolites. Betamethasone and beclomethasone, administered either systemically (per os or i.m.) or locally (by inhalation) have been studied. The determination of the urinary levels of endogenous glucocorticoids and androgens was carried out by GC-MS in electron impact ionization mode. Data were evaluated taking into account the baseline individual variability, and compared with values obtained on a control group. Detectable differences were recorded in the steroids metabolites excretion profiles between men and women. The circadian variability of the steroid profile was the same for both sexes, showing a maximum during the morning hours. After systemic treatment with synthetic glucocorticoids, the relative urinary concentrations of corticosteroids, androgens and of their metabolites were significantly altered, recording a transient decrease of the concentration of cortisol and tetrahydrocortisol and a parallel, although less pronounced, increase of the concentration of testosterone, epitestosterone and related androgenic steroids; while no effects were recorded if the administration was by inhalation.

    Full Text Available Abstract Background The metabolic syndrome is associated with increased risk for both diabetes and coronary artery disease, which insulin resistance alone does not satisfactorily explain. We propose an additional and complementary underlying mechanism of glucocorticoid resistance. Results Using acanthosis nigricans (AN and skin vasoconstrictor (SVC response to topically applied beclomethasone dipropionate as markers of insulin and glucocorticoid resistance, respectively, we compared anthropometric, biochemical, pro-inflammatory markers and the SVC response in subjects with AN in two studies: STUDY 1 was used to compare subjects with AN (Grade 4, n = 32, with those without AN (n = 68 while STUDY 2 compared these responses among a cross-section of diabetic patients (n = 109 with varying grades of AN (grade 0, n = 30; grade 1, n = 24; grade 2, n = 18; grade 3, n = 25; grade 4, n = 12. Findings In both studies there was an inverse relationship between AN Grade 4 and the SVC response, (P Conclusion An absent SVC response represents a new biomarker for the metabolic syndrome and the exaggerated inflammatory response, which characterizes the metabolic syndrome, may be an outcome of deficient glucocorticoid action in vascular tissue.

    Highly effective antiretroviral treatment has improved the life expectancy of human immunodeficiency virus (HIV) infected patients, but has led to an increase in the comorbidities related to aging, such as the chronic obstructive pulmonary disease (COPD). All this implies the need for a greater number of drugs and an increasing risk of drugs interactions with antiretroviral treatment, particularly protease inhibitors. We report a case of iatrogenic adrenal insufficiency interaction secondary to ritonavir and inhaled fluticasone in an HIV-infected patient with COPD. A review was made of the cases reported in adults in the medical literature (Medline) up to December 2012. A total of 34 cases were reported. The mean age was 4 years. The mean dose of ritonavir was 187 mg/day, while the fluticasone dose was 866 μg/day. The average time of the interaction between ritonavir and fluticasone was 8 months. In 85% of cases fluticasone was discontinued at the time of diagnosis of adrenal insufficiency/Cushing syndrome. Almost all (90%) patients had a complete resolution of the symptoms after changing the treatment. HIV-infected patients on antiretroviral therapy with protease inhibitor boosted with ritonavir which requires the use of inhaled corticosteroids, beclomethasone would be the best treatment option.

    Full Text Available Inhaled corticosteroids are potent and effective treatment agents for controlling symptoms of childhood asthma. However, there are no predictive factors that help to determine which patients with asthma are likely to be tapered off inhaled corticosteroids successfully. We examined whether any factor or combination of factors could help the clinician safely discontinue inhaled steroid therapy. Thirty-six asthmatic children whose symptoms were stable on low-dose beclomethasone dipropionate (BDP were divided by parental choice into two groups: maintenance BDP (n = 11 and no BDP (n = 25. Methacholine inhalation tests were performed at the beginning of the study and after 1 month. Twelve children (48% who had BDP discontinued developed exacerbations after 2–3 months, whereas there were no problems in the maintenance group. The no BDP group was retrospectively divided into two subgroups: exacerbation (+ and (−. The threshold to methacholine in the exacerbation (+ subgroup decreased significantly in advance of clinical symptoms. The two subgroups were analyzed statistically by two-group discriminant function analysis. The change in threshold to methacholine, the dose and potency of drugs, duration of asthma and gender (female correlated with exacerbation. These results suggest that discontinuation of inhaled steroids should be done carefully, even in stable asthmatic children. The methacholine inhalation test, gender, drugs and history may be used as references for discontinuing inhaled steroids.

    combination of an inhaled glucocorticoid and a long-acting β2-agonist (budesonide–formoterol, beclomethasone dipropionate–formoterol, fluticasone propionate–salmeterol or fluticasone furoate–vilanterol) is recommended as a first choice. Other treatment options for this phenotype include combination of long-acting bronchodilators given from separate inhalers or as a fixed combination (glycopyrronium–indacaterol or umeclidinium–vilanterol) or a triple combination of an inhaled glucocorticoid, a long-acting β2-agonist and a long-acting anticholinergic. If the patient has severe-to-very severe COPD (FEV1 chronic bronchitis and frequent exacerbations despite long-acting bronchodilators, the pharmacotherapy may include also roflumilast. ACOS is a phenotype of COPD in which there are features that comply with both asthma and COPD. Patients belonging to this phenotype have usually been excluded from studies evaluating the effects of drugs both in asthma and in COPD. Thus, evidence-based recommendation of treatment cannot be given. The treatment should cover both diseases. Generally, the therapy should include at least inhaled glucocorticoids (beclomethasone dipropionate, budesonide, ciclesonide, fluticasone furoate, fluticasone propionate or mometasone) combined with a long-acting bronchodilator (β2-agonist or anticholinergic or both).

    Full Text Available Clinical manifestation of chronic rhinitis is due to local release of mediators from inflammatory cells. Eosinophil leukocytes are important in pathogenesis of nasal hypersensitivity as well as nasal hyperreactivity [1,2]. The aim of the study was to follow-up the effect of local corticosteroid treatment on a number of eosinophils in nasal secretion of patients with chronic rhinitis. The study was prospective and controlled. A total number of 88 subjects was included in the study. Patients with chronic rhinitis who were treated with local corticosteroids (63 constituted the experimental group (37 with isolated allergic rhinitis, 10 with isolated nonallergic noninfective hyperreactive rhinitis, 10 with allergic rhinitis associated with nasal polyposis and 6 with nonallergic noninfective hyperreactive rhinitis associated with nasal polyposis. There were 25 patients with chronic rhinitis in the control group (18 with iso- lated allergic rhinitis, 2 with isolated nonallergic noninfective hyperreactive rhinitis, 3 with allergic rhinitis associated with nasal polyposis, and 2 with nonallergic noninfective, hyperreactive rhinitis associated with nasal polyposis. During the treatment with beclomethasone dipropionate aqueous nasal spray (daily dose was 400 micrograms during 6 weeks for isolated rhinitis and 6 months for associated forms of rhinitis, control examinations were regularly performed. The first control was after one week the second after six weeks, the third after three months and the fourth after six months. The same control was carried out in the control group of patients who were without therapy. Cytological examination of nasal secretions included brush method of collecting secretions, staining smears with Leishman's stain and light microscopic scrutinising of nasal smear magnified up to 1000 times. The results of the study demonstrated the highly significant decrease in the number of eosinophils after the therapy in patients with isolated

    The particle sizing performance of a Next Generation Pharmaceutical Impactor (NGI) was compared to that of an Andersen cascade impactor (ACI). A single lot of Vanceril MDIs containing beclomethasone dipropionate (BDP) was used throughout. MDIs were sampled into NGI and ACI in accordance with USP recommendations, at 30.0 and 28.3 L/min, respectively, following 1, 2, 6, and 30 actuations with or without a silicone cup or stage coating, to determine the apparent particle size distributions (PSD) of BDP. The mass balance and the statistical comparability of drug deposits were assured on a "per actuation basis" across all experiments, demonstrating "good cascade impactor practices." Interstage deposition or "wall losses" in NGI were found to be lower than those in ACI, although their determination was laborious in NGI. The PSD profiles for Vanceril from a single actuation were distinguishable between NGI and ACI, when uncoated collection surfaces were used, most specifically for drug mass coating of collection surfaces and an increased number of actuations were shown to result in PSD profile shifts for both NGI and ACI. Such effects were most pronounced for NGI, although coating the collection surfaces and/or increasing the number of actuations improved drug retention significantly on the upper stages of NGI, and thereby, minimized the effects of particle bounce of BDP from Vanceril MDIs. PSD profiles from a single actuation could be determined reliably in either of these impactors, provided that coated collection surfaces were employed; also, cumulative % mass undersize profiles were similar between instruments. However, small differences in PSD profiles still existed to support NGI's design claims for reduced "overlap" in its stage collection efficiency curves.

    The expiration of patents of brand inhalation medications and the ongoing pressure on healthcare budgets resulted in a growing market for generics. To study the use of brand and generic inhalation medication and the frequency of switching between brand and generic and between devices. In addition, we investigated whether switching affected adherence. From dispensing data from the Dutch PHARMO Database Network a cohort aged ≥ 5 years, using ≥ 1 year of inhalation medication between 2003 and 2012 was selected. Switching was defined as changing from brand to generic or vice versa. In addition, we studied change in aerosol delivery device type (e.g., DPI, pMDI, and nebulizers). Adherence was calculated using the medication possession ratio (MPR). The total cohort comprised 70,053 patients with 1,604,488 dispensations. Per calendar year, 5% switched between brand and generic inhalation medication and 5% switched between devices. Median MPRs over the first 12 months ranged between 33 and 55%. Median MPR over the total period was lower after switch from brand to generic and vice versa for formoterol (44.5 vs. 42.1 and 63.5 vs. 53.8) and beclomethasone (93.8 vs. 59.8 and 81.3 vs. 55.9). Per year, switching between brand and generic inhalation medication was limited to 5% of the patients, switching between device types was observed in 5% as well. Adherence to both generic and brand inhalation medication was low. Effect of switching on adherence was contradictory; depending on time period, medication and type, and direction of switching. Further research on reasons for switching and potential impact on clinical outcomes is warranted.

    Background Bronchial thermoplasty (BT) is a bronchoscopic procedure that improves asthma control by reducing excess airway smooth muscle. Treated patients have been followed out to 5 years to evaluate long-term safety of this procedure. Methods Patients enrolled in the Asthma Intervention Research Trial were on inhaled corticosteroids ≥200 μg beclomethasone or equivalent + long-acting-beta2-agonists and demonstrated worsening of asthma on long-acting-β2-agonist withdrawal. Following initial evaluation at 1 year, subjects were invited to participate in a 4 year safety study. Adverse events (AEs) and spirometry data were used to assess long-term safety out to 5 years post-BT. Results 45 of 52 treated and 24 of 49 control group subjects participated in long-term follow-up of 5 years and 3 years respectively. The rate of respiratory adverse events (AEs/subject) was stable in years 2 to 5 following BT (1.2, 1.3, 1.2, and 1.1, respectively,). There was no increase in hospitalizations or emergency room visits for respiratory symptoms in Years 2, 3, 4, and 5 compared to Year 1. The FVC and FEV1 values showed no deterioration over the 5 year period in the BT group. Similar results were obtained for the Control group. Conclusions The absence of clinical complications (based on AE reporting) and the maintenance of stable lung function (no deterioration of FVC and FEV1) over a 5-year period post-BT in this group of patients with moderate to severe asthma support the long-term safety of the procedure out to 5 years.

    Having a quick, practical, educational tool designed for busy child-care professionals to check whether systematic reviews (SRs) contain valid information would help them regularly update their evidence-based knowledge and apply it to their patients. Continuing our annual workshop courses encouraging paediatric hospital professionals to use evidence-based information, in a preliminary study, we compared the commonly used Critical Appraisal Skill Programme (CASP) questionnaire for appraising overall internal validity in SRs with a new, practical tool designed to check internal validity quickly. During a course in 2010, two 'teacher-brokers' taught experienced paediatric hospital professionals to use and compare the CASP and the new practical tool to appraise a Cochrane SR on beclomethasone for asthma in children by assessing internal validity only from the two most weighted randomized controlled trials in the forest plot. At 15 days and 6 months, participants then answered questionnaires designed to assess qualitative data including feelings about working together, memorization and possibly provide feedback for Cochrane reviewers. Using the CASP, participants agreed that the Cochrane SR analysed contained overall valid results. Conversely, using the new quick tool, they found poor internal validity. Participants worked well together in a group, took less time to apply the new tool than the CASP (1 vs. 2.5 hours) and provided Cochrane feedback. Our quick practical tool for teaching critical appraisal encourages busy child-care hospital professionals to work together, carefully check validity in SRs, apply the findings in clinical practice and provide useful feedback for Cochrane reviewers. © 2012 John Wiley & Sons Ltd.

    The blood-brain barrier (BBB) is a dynamic interface that maintains brain homeostasis and protects it from free entry of chemicals, toxins, and drugs. The barrier function of the BBB is maintained mainly by capillary endothelial cells that physically separate brain from blood. Several neurological diseases, such as Alzheimer's disease (AD), are known to disrupt BBB integrity. In this study, a high-throughput screening (HTS) was developed to identify drugs that rectify/protect BBB integrity from vascular amyloid toxicity associated with AD progression. Assessing Lucifer Yellow permeation across in-vitro BBB model composed from mouse brain endothelial cells (bEnd3) grown on 96-well plate inserts was used to screen 1280 compounds of Sigma LOPAC®1280 library for modulators of bEnd3 monolayer integrity. HTS identified 62 compounds as disruptors, and 50 compounds as enhancers of the endothelial barrier integrity. From these 50 enhancers, 7 FDA approved drugs were identified with EC50 values ranging from 0.76-4.56 μM. Of these 7 drugs, 5 were able to protect bEnd3-based BBB model integrity against amyloid toxicity. Furthermore, to test the translational potential to humans, the 7 drugs were tested for their ability to rectify the disruptive effect of Aβ in the human endothelial cell line hCMEC/D3. Only 3 (etodolac, granisetron, and beclomethasone) out of the 5 effective drugs in the bEnd3-based BBB model demonstrated a promising effect to protect the hCMEC/D3-based BBB model integrity. These drugs are compelling candidates for repurposing as therapeutic agents that could rectify dysfunctional BBB associated with AD.

    The zebrafish (Danio rerio) is an established model organism for developmental and biomedical research. It is frequently used for high-throughput functional genomics experiments, such as genome-wide gene expression measurements, to systematically analyze molecular mechanisms. However, the use of whole embryos or larvae in such experiments leads to a loss of the spatial information. To address this problem, we have developed a tool called Zebrafish Expression Ontology of Gene Sets (ZEOGS) to assess the enrichment of anatomical terms in large gene sets. ZEOGS uses gene expression pattern data from several sources: first, in situ hybridization experiments from the Zebrafish Model Organism Database (ZFIN); second, it uses the Zebrafish Anatomical Ontology, a controlled vocabulary that describes connected anatomical structures; and third, the available connections between expression patterns and anatomical terms contained in ZFIN. Upon input of a gene set, ZEOGS determines which anatomical structures are overrepresented in the input gene set. ZEOGS allows one for the first time to look at groups of genes and to describe them in terms of shared anatomical structures. To establish ZEOGS, we first tested it on random gene selections and on two public microarray datasets with known tissue-specific gene expression changes. These tests showed that ZEOGS could reliably identify the tissues affected, whereas only very few enriched terms to none were found in the random gene sets. Next we applied ZEOGS to microarray datasets of 24 and 72 h postfertilization zebrafish embryos treated with beclomethasone, a potent glucocorticoid. This analysis resulted in the identification of several anatomical terms related to glucocorticoid-responsive tissues, some of which were stage-specific. Our studies highlight the ability of ZEOGS to extract spatial information from datasets derived from whole embryos, indicating that ZEOGS could be a useful tool to automatically analyze gene expression

    Full Text Available Study objectives were to compare the numbers of lymphocytes and lymphocyte subpopulations in induced sputum from asthmatic patients and from healthy subjects, and to determine the effect of inhaled anti-asthmatic steroid therapy on these cell numbers. Hypertonic saline inhalation was used to non-invasively induce sputum samples in 34 patients with bronchial asthma and 21 healthy subjects. The sputum samples were reduced with dithioerythritol and absolute numbers of lymphocytes and lymphocyte subpopulations were assessed by direct immunofluorescence and flow cytometry. To assess the effect of beclomethasone dipropionate (BDP on induced sputum, numbers of lymphocytes and lymphocyte subpopulations in sputum also were evaluated after 4 weeks of BDP inhalation treatment in seven asthmatic patients. An adequate sample was obtained in 85.3% of patients with asthma and in 79.2% of the healthy subjects. Induced sputum from patients with asthma had increased numbers of lymphocytes (P = 0.009; CD4+ cells (P = 0.044; CD4+ cells-bearing interleukin-2 receptor (CD25; P = 0.016; and CD4+ cells bearing human histocompatibility leukocyte antigen (HLA-DR (P = 0.033. CD8+ cells were not increased in asthmatic patients. In patients treated with inhaled steroids, numbers of lymphocytes, CD4+ cells, CD25-bearing CD4+ cells and HLA-DR-bearing CD4+ cells in sputum decreased from pretreatment numbers (P = 0.016, 0.002, 0.003 and 0.002, respectively. Analysis of lymphocytes in induced sputum by flow cytometry is useful in assessing bronchial inflammation, and activated CD4+ lymphocytes may play a key role in the pathogenesis of airway inflammation in bronchial asthma.

    The effectiveness of pediatric asthma management programs in reducing health services utilization during exacerbations in developing countries is not widely studied. This study was carried out to assess the effectiveness of an asthma management program to reduce the overall health services utilization by acute asthma in children and adolescents. In this historical population-based real-life cohort study, we selected 582 patients with asthma aged 4-15 living in deprived areas in the town of Itabira, Brazil, of which 470 cases were assisted by the asthma management program and 112 were controls. The end point was the first physician-diagnosed asthma exacerbation occurring after study enrollment and within 12 months after admission. All 470 cases received a written plan about exacerbation self-management, including the use of inhaled albuterol at home. Three hundred and seventeen out of 470 cases (67.4%) were also treated with beclomethasone diproprionate (BDP). Both groups were comparable regarding gender, age group, and place of residence. At the end of the study, only 5% of cases vs 34% of controls did seek health services because of acute asthma (P < 0.01). Statistical difference also remained when comparing the 112 controls with the 153 cases not treated with com BDP (Hazard Ratio = 0.04, 95% CI, 0.01-0.14, P < 0.01). Results have demonstrated the effectiveness of the pediatric asthma management program in reducing dependence on the health services for acute asthma. Effectiveness was also observed in subjects with no use of BDP. © 2010 John Wiley & Sons A/S.

    In the guideline for asthma management, it is important to find the personal best value of peak expiratory flow (best PEF). Recently, we have substituted the highest value of PEF in daily life under good control (daily highest PEF) for the best PEF. In the present study, we considered whether the daily highest PEF could be used as the best PEF or not. Subjects were 30 asthmatics who were well controlled but whose baseline PEF values were less than 80 percent of predicted values. We compared the daily highest PEF and the highest of PEF obtained after repeated inhaled beta2-agonist (salbutamol MDI every 20 minutes three times). All subjects then received 1600 microg/day of beclomethasone dipropionate (BDP) for 4 to 8 weeks. We studied the effect of high-dose inhaled steroid treatment on each PEF value and compared the daily highest PEF and the highest PEF obtained after using repeated salbutamol MDI during high dose inhaled steroid therapy on the examination day again. The baseline PEF, daily highest PEF and the highest PEF obtained after salbutamol MDI were significantly less than the each values obtained after high-dose BDP. The best PEF value of them was the value obtained after repeated salbutamol MDI during high dose BDP. We suggest that the daily highest PEF under good control is not a substitute for best PEF because it changes according to the degree of improvement of airway inflammation. We recommend that a course of high dose inhaled steroid is effective in finding the best value of PEF for each individual with moderate asthma.

    Despite regular inhalation of beta-agonists, topical steroids and anticholinergic aerosols and the achievement of therapeutic blood levels of theophylline, some asthmatics have rapidly fluctuating levels of peak flow measurements throughout the day. Often little or no improvement is obtained with larger doses of corticosteroids. Before embarking on more intense drug therapy, attention should be paid to conscientious adherence to the prescribed regimen and avoidance of aspirin and tartrazine, as well as to exposure to allergens such as those associated with household pets. A number of newer therapeutic options are related to the use of air jet or ultrasonic nebulizers, that allow liquid forms of inhalation agents to be taken slowly in the home environment. In this regard, combination therapy with a beta-agonist and the anticholinergic ipratropium has been shown to have bronchodilating properties superior to either agent used alone. Secondly, sodium cromoglycate in its liquid form appears to have bronchodilator properties; taken on a regular basis, four times per day, it appears to have a steroid-sparing effect. Two alternatives are available for increasing the intensity of corticosteroid therapy, other than by prolonged, high-dose prednisone. The first is that of high-dose inhaled beclomethasone (up to 2000 micrograms/day) using the 250 micrograms/puff inhaler. The second is that of intravenous therapy with methylprednisolone, recently shown to have lung permeability superior to that of prednisolone. Office patients can be treated with occasional or even regular 'pulse' doses of methylprednisolone, an approach that is now finding acceptance in the management of the inflammatory alveolitides.

    Nebulization is a common method of medical aerosol generation and it is largely used by adults and children all over the world, both for emergency treatment of acute illness and for long-term home treatment of lung diseases. The aim of this study was to determine the differences in nebulization of inhaled corticosteroids among four representative types of compressor/nebulizers. Twelve compressor/jet nebulizers from four commercial sources were studied (three for each type): Clenny (MEDEL), Turbo Boy/LC Plus (PARI), Nebula Nuovo/MB5 (MARKOS MEFAR) and Maxaer (ARTSANA) compressor/Sidestream (Medic-Aid Ltd.) nebulizer. We compared the required time for the treatment (nebulization time), output/minutes, compressor pressures, and aerosol characteristics of inhaled corticosteroids: Beclomethasone dipropionate, Flunisolide, Fluticasone propionate and Budesonide. Nebulization Times showed a significant difference between nebulizer and inhaled corticosteroids for Clenny, Turbo Boy, and Maxaer. A considerable difference in the output of nebulized drugs was observed through the compressors/nebulizers. MMAD of all inhaled corticosteroids was significantly different among the four nebulizers. The percentage of particles 90%), whereas with flunisolide was good only for Clenny (98.8%) and Maxaer (96.3%), and with fluticasone only for Clenny (98%), Turbo Boy (99.1%), and Maxaer (86%). Also percentage of particles <2 microm showed significant variability among the devices. Our results clearly demonstrate that compressor/nebulizer unit plays a key role in the effectiveness of the treatment during inhaled corticosteroid therapy, and that several differences exist in the performance of the different nebulizers studied. Therefore, the device has the same importance of the compound to reach the best clinical response in the inflammatory diseases of the lower airways.

    European and United States Pharmacopoeia compendial procedures for assessing the in vitro emitted dose and aerodynamic size distribution of a dry powder inhaler require that 4.0 L of air at a pressure drop of 4 kPa be drawn through the inhaler. However, the product performance should be investigated using conditions more representative of what is achievable by the patient population. This work compares the delivered dose and the drug deposition profile at different flow rates (30, 40, 60, and 90 L/min) of Foster NEXThaler(®) (beclomethasone dipropionate/formoterol fumarate), Seretide(®) Diskus(®) (fluticasone propionate/salmeterol xinafoate), and Symbicort(®) Turbohaler(®) (budesonide/formoterol fumarate). The delivered dose uniformity was tested using a dose unit sampling apparatus (DUSA) at inhalation volumes either 2.0 or 4.0 L and flow rates 30, 40, 60, or 90 L/min. The aerodynamic assessment was carried out using a Next Generation Impactor by discharging each inhaler at 30, 40, 60, or 90 L/min for a time sufficient to obtain an air volume of 4 L. Foster(®) NEXThaler(®) and Seretide(®) Diskus(®) showed a consistent dose delivery for both the drugs included in the formulation, independently of the applied flow rate. Contrary, Symbicort(®) Turbohaler(®) showed a high decrease of the emitted dose for both budesonide and formoterol fumarate when the device was operated at airflow rate lower that 60 L/min. The aerosolizing performance of NEXThaler(®) and Diskus(®) was unaffected by the flow rate applied. Turbohaler(®) proved to be the inhaler most sensitive to changes in flow rate in terms of fine particle fraction (FPF) for both components. Among the combinations tested, Foster NEXThaler(®) was the only one capable to deliver around 50% of extra-fine particles relative to delivered dose. NEXThaler(®) and Diskus(®) were substantially unaffected by flow rate through the inhaler in terms of both delivered dose and fine particle mass.

    Long-term usage of systemic steroids is associated with multiple side effects. One of the major morbidities is due to its effect on bone metabolism leading to bone loss and resulting in skeletal fractures. This study was conducted to determine the effects of inhaled steroids on bone mineral density (BMD) and biochemical bone markers. Twenty-four children with frequent episodic or mild persistent asthma who satisfied the clinical criteria for starting on inhaled corticosteroids (ICS) were enrolled into the study. The BMD scan was done using dual energy X-ray absorptiometry, prior to starting ICS therapy and 6 months later. Biochemical markers of bone metabolism, (i) serum osteocalcin as a bone formation marker, and (ii) urinary deoxypyridinoline (Upd) as a bone resorption marker, were taken prior to ICS treatment and at 2 monthly intervals. The biochemical markers were all taken in the morning. Twenty-four, age- and sex-matched children with mild episodic asthma, not requiring ICS, were used as controls for the BMD measurements. The BMD scan was done upon enrollment into the study and 6 months later. Twenty-four children on ICS and 24 controls completed the study. The subjects were on a mean dose of beclomethasone dipropionate (BDP) 0.4 mg/day. One subject needed a short course of Prednisolone in the early treatment period. None of the controls needed oral steroid therapy. One child in the control group sustained a greenstick fracture after an accidental fall. The mean rate of change of BMD was 1.8% +/- 12.3 in the subjects on BDP. This was lower than the 6.1% +/- 10.6 among the control subjects. However, this difference did not reach statistical significance (P = 0.16). There was a significant increase in serum osteocalcin level after 6 months of BDP treatment from 66.83 +/- 22.71 ng/mL to 81.61 +/- 24.66 ng/mL (P Upd from 36.2 +/- 47.1 nmol/mmol creatinine to 21.4 +/- 6.92 nmol/mmol creatinine.

Two review authors independently screened all records identified in the searches. We used a data extraction tool in Microsoft Excel to manage searches and document reasons for inclusion and exclusion, and to extract descriptive and numerical data from trials meeting the inclusion criteria.The prespecified primary outcomes were exacerbations requiring oral steroids, asthma control, and all-cause serious adverse events. Despite conducting extensive searches of electronic databases, trial registries and manufacturers' websites we identified no trials matching the inclusion criteria.After removing duplicates, we screened 1031 abstracts, and assessed 43 full-text articles for inclusion. We identified several adult studies, which will be summarised in a separate review (Ahmad 2014). The most common reasons for exclusion after viewing full texts were 'wrong comparison' (n = 22) and 'adult population' (n = 18).Some adult studies recruited adolescents from age 15, but none reported data separately for those under 18. There is currently no evidence from randomised trials to inform the discontinuation of LABAs in children once asthma control is achieved with ICS plus LABA. It is disappointing that such an important issue has not been studied, and a randomised double-blind trial recruiting children who are controlled on ICS plus LABA is warranted. The study should be large enough to assess children of different ages, and to measure the important safety and efficacy outcomes suggested in this review over at least six months.The only randomised evidence for stopping LABA has been conducted in adults; it will be summarised in a separate review.

    Anti-leukotrienes (5-lipoxygenase inhibitors and leukotriene receptors antagonists) serve as alternative monotherapy to inhaled corticosteroids (ICS) in the management of recurrent and/or chronic asthma in adults and children. To determine the safety and efficacy of anti-leukotrienes compared to inhaled corticosteroids as monotherapy in adults and children with asthma and to provide better insight into the influence of patient and treatment characteristics on the magnitude of effects. We searched MEDLINE (1966 to Dec 2010), EMBASE (1980 to Dec 2010), CINAHL (1982 to Dec 2010), the Cochrane Airways Group trials register, and the Cochrane Central Register of Controlled Trials (Dec 2010), abstract books, and reference lists of review articles and trials. We contacted colleagues and the international headquarters of anti-leukotrienes producers. We included randomised trials that compared anti-leukotrienes with inhaled corticosteroids as monotherapy for a minimum period of four weeks in patients with asthma aged two years and older. Two review authors independently assessed the methodological quality of trials and extracted data. The primary outcome was the number of patients with at least one exacerbation requiring systemic corticosteroids. Secondary outcomes included patients with at least one exacerbation requiring hospital admission, lung function tests, indices of chronic asthma control, adverse effects, withdrawal rates and biological inflammatory markers. Sixty-five trials met the inclusion criteria for this review. Fifty-six trials (19 paediatric trials) contributed data (representing total of 10,005 adults and 3,333 children); 21 trials were of high methodological quality; 44 were published in full-text. All trials pertained to patients with mild or moderate persistent asthma. Trial durations varied from four to 52 weeks. The median dose of inhaled corticosteroids was quite homogeneous at 200 µg/day of microfine hydrofluoroalkane-propelled beclomethasone or

    effects of IGs on bone metabolism markers and bone mineral density in adults and in pediatric patients. The reviewed studies do not provide uniform results. Nevertheless, in general they suggest that IGs can affect metabolism and bone mineral density, especially: 1 when high doses are administered (more than 400 µg/day in children and more than 800 µg/day in adults, 2 in pediatric patients, in whom growth in stature can also be affected, 3 in patients whose intake of calcium and vitamin D is inadequate, and 4 in postmenopausal women not undergoing hormone replacement therapy. In general, at therapeutically equivalent doses, beclomethasone has a greater deleterious effect on bone than does budesonide, which in turn has more of an effect than does fluticasone. In addition to the obvious precaution of using the lowest effective dose, other proposed preventive measures include: 1 adequate instruction on the use of aerosols, 2 the use of large volume spacer devices, 3 rinsing the mouth after administering IGs, and 4 dietary adjustments or supplements in order to ensure an adequate intake of calcium and vitamin D.
