Abstract Pharmacists acting in pharmacies and drugstores stores are some of the most accessible healthcare providers and the last to intervene before the patient takes their medicine. This puts the pharmacist in a position of authority that should be harnessed for the benefit of health. Thus, this professional is strategic for performing pharmacovigilance. Our objective of this study was to interrogate the practice of pharmacists in relation to pharmacovigilance activities, and to identify difficulties and possible stimuli for the improvement these activities in pharmacies and drugstores. The information was collected through an online questionnaire via Survey Monkey®. The data were analyzed statistically using SPSS software. Responses were received from 5174 pharmacists: mostly young women within five years of graduation and experience in pharmaceutical retail. 81% of them reported having identified suspected substandard medicines, but only 16% used the Brazilian notification system Notivisa. More than 85% of pharmacists agreed with the importance of pharmacovigilance and the recognition of reporting services as part of pharmacist duties and pharmaceutical care. The main barriers to making notifications were the lack of access and knowledge about Notivisa. Pharmacists agreed that simplifying the system would be a stimulus for notifications, and requested more feedback from notifications, as well as material and courses to understand the notification process. Pharmacists have important data to feed into pharmacovigilance systems, recognize their responsibilities and are willing to contribute, but still demonstrate low compliance. Simplification of the system and training on it are likely to increase notifications.

The aim of this study was to evaluate efficacy and safety of amfepramone, fenproporex and mazindol as a monotherapy for the treatment of obese or overweight patients. A systematic review of primary studies was conducted, followed by a direct meta-analysis (random effect) and mixed treatment comparison. Medline and other databases were searched. Heterogeneity was explored through I2 associated with a p-value. Of 739 identified publications, 25 were included in the meta-analysis. The global evaluation of Cochrane resulted in 19 studies with a high level of bias and six with unclear risk. Due to the lack of information in primary studies, direct meta-analyses were conducted only for amfepramone and mazindol. Compared to placebo, amfepramone resulted in higher weight loss in the short-term (<180 days; mean difference (MD) -1.281 kg; p<0.05; I2: 0.0%; p=0.379) and long-term (≥180 days; MD -6.518 kg; p<0.05; I2: 0.0%; p=0.719). Only studies with long-term follow up reported efficacy in terms of abdominal circumference and 5-10% weight reduction. These results corroborated the finding that the efficacy of amfepramone is greater than that of placebo. Treatment with mazindol showed greater short-term weight loss than that with placebo (MD -1.721 kg; p<0.05; I2: 0.9%; p=0.388). However, metabolic outcomes were poorly described, preventing a meta-analysis. A mixed treatment comparison corroborated the direct meta-analysis. Considering the high level of risk of bias and the absence of important published outcomes for anti-obesity therapy assessments, this study found that the evaluated drugs showed poor evidence of efficacy in the treatment of overweight and obese patients. Robust safety data were not identified to suggest changes in their regulatory status.

Resumo A farmacoterapia antiobesidade ainda é alvo de amplo debate científico e político; não por acaso, já que há pouca confiabilidade tanto no âmbito dos estudos primários quanto no dos secundários, seja pelo reduzido tamanho amostral, seja pela elevada heterogeneidade e/ou pela baixa qualidade metodológica. Por muitos anos, o Brasil foi mencionado como um dos maiores consumidores de inibidores de apetite do mundo, com evidências de uso irracional dessa classe de medicamentos. Portanto, o país foi palco de debate que dividiu a Agência Nacional de Vigilância Sanitária (Anvisa) e as sociedades médicas quanto à manutenção do registro de anfepramona (dietilpropiona), mazindol e femproporex. Nesse contexto, o presente comentário apresenta novos argumentos para essa discussão e ainda recomendações para estudos futuros.

Summary Antiobesity pharmacotherapy remains the main point of disagreement among both scientists and regulators. This is probably due to small sample sizes, high levels of heterogeneity, and low methodological quality. For many years, Brazil was one of the largest consumers of appetite suppressants worldwide, with evidence of irrational use of this drug class. Therefore, the country was the scene of a debate that divided the Brazilian Health Surveillance Agency (Anvisa - Agência Nacional de Vigilância Sanitária) and medical societies over the maintenance record of diethylpropion, mazindol and fenproporex. In this context, this commentary presents new arguments to contribute to the discussion, as well as recommendations for future studies.

ABSTRACT Pharmacists and their pharmacies have been evolving in their roles as health promoters in Brazil. Some examples are the recent legislation reaffirming the role of Brazilian pharmacies as health institutions, rather than having only a commercial profile, giving greater clarity to pharmacists about their roles as health care providers. This evolution came with the recognition that is already seen in other developed countries, confirming the need for the pharmacist as a health promoter, and not simply a dispenser of drugs in society. This study has obtained the profile and activities of community pharmacists, as well as the quality indicators of private community pharmacies throughout the State of Paraná through the application of an online survey sent to pharmacists in the state. Out of all pharmacists surveyed, 533 were part of the final analysis, being the pharmacists to complete the survey in full. Participants were mostly female (69.4%) and were, on average, 35.2 ± 9.2 years old. Of these, 60% worked in pharmacy chains and just 37% of all pharmacist respondents were issuing the Declaration of Pharmaceutical Services. The current study showed that many pharmaceutical services are not adopted by pharmacies as these services bring no significant financial reward. Regarding the structure, the Paraná State showed that pharmacies present a good overall structure. The kind of pharmacy (chain or independent) influenced the pharmaceutical services provided and the available structure, where the independent pharmacies provide a wider range of services and have better structure. This study was able to identify the profile and behaviors of pharmacists and also the quality indicators of pharmacies in Paraná State.

ABSTRACT Objectives: this observational study aimed to describe the discrepancies identified during medication reconciliation on patient admission to cardiology units in a large hospital. Methods: the medication history of patients was collected within 48 hours after admission, and intentional and unintentional discrepancies were classified as omission, duplication, dose, frequency, timing, and route of drug administration. Results: most of the patients evaluated were women (58.0%) with a mean age of 59 years, and 75.5% of the patients had a Charlson comorbidity index score between 1 and 3. Of the 117 discrepancies found, 50.4% were unintentional. Of these, 61.0% involved omission, 18.6% involved dosage, 18.6% involved timing, and 1.7% involved the route of drug administration. Conclusion: this study revealed a high prevalence of discrepancies, most of which were related to omissions, and 50% were unintentional. These results reveal the number of drugs that are not reincorporated into the treatment of patients, which can have important clinical consequences.

Dos 24 estudos que avaliaram segurança, 21% mostraram evidência desfavorável ao uso do medicamento. No geral, a evidência encontrada nos estudos incluídos nesta revisão é favorável ao uso dos medicamentos avaliados. Entretanto, há grupos terapêuticos para os quais há lacunas na evidência.</p>

<p>Over-the-counter medicines are available without prescription because of their safety and effectiveness, to treat minor ailments and symptoms. The objective of the study was to analyze the availability and quality of systematic reviews published about nonprescription medicines, identifying the groups for which there are gaps in evidence. We identified published articles through the Cochrane Database of Systematic Review and MEDLINE, from the start of the database until May 2012, using the search terms "nonprescription drugs," "over the counter," and "OTC." We searched for articles that describe systematic reviews addressing the efficacy and safety of drugs dispensed without a prescription, according to the lists published by the Association of the European Self-Medication Industry and in Brazil, in the clinical conditions listed in Groups and Specified Therapeutic Indications. We included 49 articles, 18 articles were of moderate quality and 31 of high quality. Of the studies, 74.5% demonstrated efficacy in favor of the use of drugs evaluated. Of the 24 studies that evaluated safety, 21% showed evidence unfavorable to the drug. Overall, the evidence found in the studies included in the overview is favorable to the use of the drugs evaluated. However, there are gaps in evidence for some therapy groups.</p>

Conduziu-se uma revisão sistemática e metaanálise de ensaios clínicos randomizados em pacientes com psoríase moderada a grave, tratados com biológicos ou placebo por 10 a 14 semanas. Foram incluídos 41 estudos, com escore de Jadad médio de 4,4, totalizando 15.586 pacientes. Para os desfechos de eficácia PASI 50, 75 e 90 os resultados não são conclusivos para definir qual é o melhor agente biológico no curto prazo. Não houve diferença estatística entre placebo e biológicos para ocorrência de infecções e eventos ad-versos sérios. Ustequinumabe 45mg foi o biológico com menor ocorrência de descontinuação por conta de eventos adversos. Baseado na evidência até então disponível, não é possível determinar qual agente biológico é o melhor para se atingir resposta PASI 50, 75 e 90 após 10-14 semanas de tratamento. Para o mesmo intervalo, a segurança global parece ser a mesma para todos os biológicos e ustequinumabe 45mg o tratamento melhor tolerado. Para melhor compreender a eficácia e segurança, meta-análise indireta comparando droga-a-droga são necessárias já que ensaios clínicos randomizados podem não ser viáveis.

We conducted a systematic review and metaanalysis of randomized placebo-controlled trials in moderate-to-severe psoriasis treated with biological agents, with a follow-up of 10-14 weeks. Overall, 41 studies, with mean Jadad score of 4.4, and 15,586 patients were included. For the efficacy outcomes PASI 50, 75 and 90 our findings are not conclusive to point what biological agent has the greatest response in short term follow-up. There were no statistical differences between placebo and biologics for the occurrence of infections and serious adverse events. Ustekinumab 45mg showed lower withdrawal due to adverse events compared with the placebo. Based on data available up to now, it is not possible to determine which biological agent is the best for PASI 50, 75 or 90 after 10-14 weeks of treatment. At the same follow-up, overall safety seems to be the same for all biological agents and Ustekinumab 45mg the most well tolerated drug. To better understand efficacy and safety, indirect meta-analysis comparing drug-to-drug is required since randomized placebo-controlled trials may not be feasible.

Se incluyeron 41 estudios con una puntuación de Jadad de 4,4, un total de 15.586 pacientes. Para variables de eficacia PASI 50, 75 y 90, los resultados no son concluyentes para definir cuál es el mejor agente biológico en el corto plazo. No hubo diferencia estadística entre el placebo y la ocurrencia biológica de las infecciones y los eventos adversos graves. Ustequinumabe 45mg fue el biológico con una menor incidencia de la interrupción debido a eventos adversos. Basado en la evidencia disponible hasta el momento, no es posible determinar qué agente biológico es lograr la mejor respuesta PASI 50, 75 y 90 después de 10-14 semanas de tratamiento. Para el mismo período, la seguridad global parece ser el mismo para todos los tratamientos y ustequinumabe 45mg el mejor tolerado. Para comprender mejor la eficacia y seguridad, es necesario un metaanálisis indirecto comparando medicamento a medicamento.

Todos os pacientes com Diabetes Mellitus (DM) tipo 1 recebem insulina. Neste estudo, avaliaram-se eficácia, segurança e tolerabilidade de insulinas humanas e análogas. Realizou-se uma revisão sistemática e meta-análise, de acordo com o preconizado pela Colaboração Cochrane. Na ausência de estudos clínicos comparando insulinas entre si, realizaram-se meta-análises de comparações indiretas a fim de estabelecer diferenças entre tratamentos ativos. Incluíram-se estudos de 1995 a 2010. Resultados de HbA1c, episódios de hipoglicemia e hipoglicemia noturna foram extraídos e analisados. Após leitura de resumos e, posteriormente, de artigos na íntegra, selecionaram-se 35 ensaios clínicos randomizados, totalizando 4206 pacientes utilizando insulina análoga de longa duração e 5733 pacientes insulina análoga de curta duração. Os resultados não demonstraram diferença estatisticamente significativa para redução de HbA1c entre glargina e detemir (uma vez ao dia) comparados a NPH. No entanto, insulina detemir utilizada duas vezes ao dia reduz a HbA1c (-0.14% [95% CI: -0.21 to -0.08]; p<0.0001; I²=0%). Comparações diretas e indiretas indicam que não existem diferenças significativas na médica de redução de HbA1c, independente da posologia de detemir, sendo estes resultados de eficácia e segurança consistentes. Os resultados indicam que insulinas análogas de longa ou curta duração apresentam pequenas vantagens, quando comparadas às insulinas tradicionais. Ademais, não existem diferenças entre eficácia e segurança quando comparamos insulinas análogas entre si.

All patients with Diabetes Mellitus (DM) receive insulin therapy. In this study, we evaluated the efficacy, safety and tolerability of human insulin and insulin analogues. We performed a systematic review of the literature and a meta-analysis according to the Cochrane Collaboration methodology. In the absence of clinical studies comparing insulins, we performed a mixed treatment comparison to establish the differences between the active treatments. We included studies published from 1995 to 2010. HbA1c results, episodes of hypoglycemia and nocturnal hypoglycemia data were extracted and analyzed. Thirty-five randomized clinical trials were selected after examining the abstract and a full text review. These studies included 4,206 patients who received long-acting insulin analogues and 5,733 patients who received short-acting insulin analogues. Pooled data regarding efficacy indicated no significant differences in HbA1c values between glargine or detemir (once daily) and NPH insulin. However, a twice-daily dose of detemir produced differences in HbA1c values that favored detemir (-0.14% [95% CI: -0.21 to -0.08]; p<0.0001; I²=0%). Direct and indirect comparisons are consistent and show that there were no significant differences between human insulin and insulin analogues in efficacy or safety. Our results indicate that long- and short-acting insulin analogues offer few clinical advantages over conventional human insulin.

The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states. A Markov model was developed in a time horizon of 40 years with annual cycles for three groups of: HBeAg positive, HBeAg negative, and all patients. These strategies were compared to a fourth group that received no treatment. Discount rates of 5% were applied and sensitivity analyses were performed. Tenofovir offered the best cost-utility ratio for the three evaluated models: U$397, U$385 and U$384 (per QALY, respectively, for HBeAg positive, negative, and all patients). All other strategies were completely dominated because they showed higher costs and lower effectiveness than tenofovir. The sequence of cost-utility in the three models was: tenofovir, entecavir, lamivudine, adefovir, telbivudine, pegylated interferon alpha, and interferon alpha. In the sensitivity analysis, adefovir showed lower cost-utility than telbivudine in some situations. The study has some limitations, primarily related to the creation of scenarios and modeling. In this study, tenofovir presented the best cost-utility ratio. The results obtained in this study will be valuable in decision-making and in the review of the clinical protocol, mainly involving the allocation of available resources for health care.

OBJETIVO: Analisar as intervenções realizadas por farmacêuticos clínicos durante a revisão de prescrições médicas das Unidades de Terapia Intensiva Adulto, Terapia Intensiva Cardiológica e de Cardiologia Clínica de um hospital universitário terciário do Brasil. MÉTODOS: A análise de prescrições foi realizada diariamente com avaliação dos seguintes parâmetros: dose, intervalo de administração, apresentação e/ou forma farmacêutica, presença de medicamentos inapropriados/desnecessários, necessidade de medicamento adicional, alternativas terapêuticas mais adequadas, presença de interações medicamentosas relevantes, inconsistências nas prescrições, incompatibilidades físico-químicas/estabilidade da solução. A partir dessa avaliação, os problemas relacionados aos medicamentos foram classificados, bem como as intervenções farmacêuticas resultantes, conforme estabelecido pelo manual de farmácia clínica do hospital. RESULTADOS: Durante o estudo, um total de 6.438 prescrições foi avaliado e foram realizadas 933 intervenções farmacêuticas. Os medicamentos mais envolvidos nos problemas foram: ranitidina (28,44%), enoxaparina (13,76%) e meropenem (8,26%). A aceitação das intervenções foi de 76,32%. O problema mais comumente encontrado foi relacionado à dose, representando 46,73% do total. CONCLUSÃO: Até 14,6% das prescrições avaliadas apresentaram algum problema relacionado a medicamentos. As intervenções farmacêuticas promoveram mudanças positivas em sete a cada dez dessas prescrições.

OBJECTIVE: To analyze the clinical pharmacist interventions performed during the review of prescription orders of the Adult Intensive Care, Cardiologic Intensive Care, and Clinical Cardiology Units of a large tertiary teaching hospital in Brazil. METHODS: The analysis took place daily with the following parameters: dose, rate of administration, presentation and/or dosage form, presence of inappropriate/unnecessary drugs, necessity of additional medication, more proper alternative therapies, presence of relevant drug interactions, inconsistencies in prescription orders, physical-chemical incompatibilities/solution stability. From this evaluation, the drug therapy problems were classified, as well as the resulting clinical interventions. RESULTS: During the study, a total of 6,438 drug orders were assessed and 933 interventions were performed. The most prevalent drug therapy problems involved ranitidine (28.44%), enoxaparin (13.76%), and meropenem (8.26%). The acceptability of the interventions was 76.32%. The most common problem found was related to dose, representing 46.73% of the total. CONCLUSION: Our study showed that up to 14.6% of the prescriptions reviewed had some drug therapy problem and the pharmacist interventions have promoted positive changes in seven to ten of these prescriptions.

O objetivo foi fornecer dados atualizados sobre eficácia clínica, segurança e tolerabilidade do uso de abatacepte para o tratamento da artrite reumatoide. Realizaram-se uma revisão sistemática (com dados até junho/2011) e metanálises. Somente estudos clínicos controlados randomizados comparando o abatacepte (10 mg/kg) com placebo, ambos com uso concomitante de metotrexato, foram incluídos; todos possuíam qualidade alta ou moderada. A eficácia foi avaliada baseando-se em mudanças no ACR, DAS e HAQ; a segurança foi avaliada pelos eventos adversos e infecções graves, malignidades e mortes e a tolerabilidade pelo abandono do tratamento devido a eventos adversos (graves ou não) e falta de eficácia. Todos esses parâmetros foram avaliados ao final de um ano de tratamento. Nove estudos se adequaram aos critérios de inclusão, envolvendo 4219 pacientes. Em todos os parâmetros avaliados, o grupo tratado com abatacepte obteve melhores resultados, exceto para a melhora (>0,3) no HAQ (sem diferença estatisticamente significativa). Nenhum critério de segurança ou tolerabilidade apresentou diferença significativa entre os grupos, com exceção dos abandonos devido à falta de eficácia (grupo abatacepte apresentou resultados favoráveis em relação ao controle). O abatacepte possui maior eficácia quando comparado com o placebo, sem diferença significativa entre os grupos em termos de segurança.

The objective is to provide an update on the clinical efficacy, safety and tolerability of the use of abatacept for treating rheumatoid arthritis. A systematic review (up to June 2011) followed by meta-analyses was performed. Randomized controlled clinical trials comparing abatacept at a dose of 10 mg/kg with a placebo, both with concomitant methotrexate, were used. Only high- or moderate-quality studies were included. The efficacy was evaluated based on changes in the ACR, DAS and HAQ; safety was assessed based on serious adverse events, serious infections, malignancies and deaths; tolerability was evaluated based on the withdrawals due to adverse events, serious adverse events and lack of efficacy. All these parameters were evaluated within one year of treatment. Nine studies met the inclusion criteria, comprising 4,219 patients. For all of the efficacy parameters, the abatacept group had better results than the placebo group, except in the case of HAQ improvement >0.3, which presented no statistically significant difference. None of the safety parameters presented a significant difference between the groups. The tolerability parameters were also similar between groups, with the exception of withdrawals due to lack of efficacy. For this criterion, the abatacept group presented favorably compared to the control group. Abatacept showed a higher efficacy compared to placebo without significant differences between the abatacept and control group in terms of safety.
