Pharmacovigilance: an evaluation on the practice of pharmacists acting in pharmacies and drugstores

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.

Quality of evidence of anti-obesity pharmacotherapy: an overview of systematic reviews

The safety and effectiveness of main anti-obesity drugs are controversial, and there is no consensus among regulatory agencies regarding anti-obesity drugs. We undertook an overview of systematic reviews (SR) of randomized controlled trials (RCT) to summarize the quality of evidence related to anti-obesity drugs. Data sources included Medline, Scopus, The Cochrane Library and PROSPERO. Twenty-one SR (564 RCT; average of 2,356 participants per review) satisfied the inclusion criteria. Ten SR presented a high level of heterogeneity, and only five SR included sensitivity analyses. The most important limitations reported by the SR were a high level of attrition, a small sample size, and a short follow-up. Eight different outcomes for efficacy were used, 15 different outcomes for biomarkers were used, and nine different outcomes for safety were used. Conclusions: In conclusion, the quality of SR pertaining to anti-obesity drugs is low, and these reviews have a high level of heterogeneity. Future SR should present more detailed population inclusion criteria, larger sample sizes, and focus variables reported in a predefined anti-obesity core outcome set.(AU)

Prescription errors and associated factors in patients with oncologic and hematologic diseases in a tertiary hospital

Medication errors extend inpatient stay, increase costs and double the risk of death. Identify patients more likely to present prescription errors would be one manner that could be used to decrease the impact of such events. Thus, the present study identified the prevalence of prescription errors with patients with oncohematologic diseases and the factors associated with these events. Methods: A cross-sectional study was performed in a Brazilian tertiary hospital. Data regarding service, patients and their clinical condition, drug therapy and prescription errors were retrieved and analyzed. Results: Of 344 drug prescriptions identified, 26.2% showed at least one prescription error, mainly involving a wrong drug (48.3%). According to the logistic regression, the factors associated with errors include: presence of neutropenia OR 1.92 (95% CI 1.10­3.35), physicians on holiday or weekend shifts OR 0.40 (95% CI 0.18­0.86) and prescriptions with higher proportion of parenteral administration route OR 1.05 (95% CI 1.03­1.08). Conclusion: In conclusion, identify the factors associated with errors can be useful in developing clinical tools for predicting patients at higher risk for the occurrence of prescribing errors, as well as to contribute to the optimization of health professionals' clinical performance.(AU)

Systematic review and meta-analysis of the efficacy and safety of amfepramone and mazindol as a monotherapy for the treatment of obese or overweight patients

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.

Reduction of glycated hemoglobin (HbA1c) and cost analysis of treatment with insulin analogues in the state of Paraná: a retrospective cohort study / Redução de hemoglobina glicada (HbA1c) e análise de custo do tratamento com análogas insulinas no estado do Paraná: estudo de coorte retrospectivo

Objective: Diabetes mellitus (DM) is a serious public health problem in Brazil. The goal of this study was to evaluate the effectiveness of long-acting insulin analogues in controlling glycemia in type 1 DM patients and to analyze the direct costs of the treatment. Methods: A retrospective cohort study was undertaken with data collected from the State Health Secretary's 2nd Regional Health Center from the State of Paraná. After randomization, socio-demographic data, the source of their drug prescriptions, and the pharmacotherapeutic profiles of the drugs were collected, along with clinical outcome information, such as glycated hemoglobin (HbA1c) and fasting plasma glucose levels. The direct costs of treatment with analogue insulin were evaluated based on the drugs and supplies acquisition data from the Center for Drugs, Paraná Cemepar. Results: One hundred and forty-eight type 1 diabetes mellitus patients, older than 18 years of age, were included in the cohort study. The HbA1c reduction after the insulin treatment was 0.36 ± 2.75, and the direct costs to reduce this parameter by 1% over a period of 24 months were U$ 1,806. The estimated costs to reduce HbA1c by 1% are U$ 5,016. Conclusions: In this study, we were able to estimate the public health system costs of using insulin analogues to reduce HbA1c by 1% in patients with type 1 DM. This information will assist clinicians in decision-making regarding insulin treatment.

Objetivo: Diabetes mellitus (DM) é um grave problema de saúde pública no Brasil. O objetivo deste estudo foi avaliar a redução da HbA1c em pacientes usuários de insulinas análogas de longa duração no controle glicêmico de pacientes com DM tipo 1 e avaliar custos diretos do tratamento com insulinas análogas. Métodos: O estudo é uma coorte retrospectiva e análise de custos para o tratamento de DM tipo 1, com pacientes pertencentes a 2a Regional de Saúde do estado do Paraná. Após randomização dos pacientes, foram coletados dados sociodemográficos, origem da prescrição e seu perfil farmacoterapêutico, além dos desfechos clínicos, como hemoglobina glicada (HbA1c) e glicemia em jejum. Foi realizada uma análise dos custos diretos do tratamento com insulinas análogas, e os valores foram obtidos por meio dos dados de compra dos medicamentos e insumos realizados pelo Centro de Medicamentos Básicos do Paraná (Cemepar). Resultados: Foram incluídos 148 pacientes maiores de 18 anos. A variável avaliada foi redução na HbA1c que, entre os pacientes, foi de 0,36 ± 2,75. Os resultados médios dos custos diretos totais do tratamento com DM tipo 1 durante 24 meses foram de R$ 7.224,00, para obter redução em 0,36% dos valores de HbA1c. O custo teórico para a redução em 1% de HbA1c é de R$ 20.064,00. Conclusões: Neste estudo foi possível estimar o custo para o sistema público de saúde, da redução de 1% da HbA1c em pacientes com DM tipo 1 usando insulinas análogas. Essa informação serve de subsídios para gestores e clínicos na tomada de decisão do tratamento com insulinas.

Quality indicators of pharmacists' services in community pharmacies in Paraná State, Brazil

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.

Analysis of the discrepancies identified during medication reconciliation on patient admission in cardiology units: a descriptive study / Análise das discrepâncias encontradas durante a conciliação medicamentosa na admissão de pacientes em unidades de cardiologia: um estudo descritivo / Análisis de las discrepancias encontradas durante la conciliación medicamentosa en la admisión de pacientes en unidades de cardiología: un estudio descriptivo

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.

Review of the efficacy and safety of over-the-counter medicine / Revisão sobre a eficácia e segurança de over-the -counter medicina

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...

Efficacy and safety of biologics in the treatment of moderate to severe psoriasis: a comprehensive meta-analysis of randomized controlled trials / Eficácia e segurança de agentes biológicos no tratamento da psoríase moderada a grave: uma meta-análise de ensaios clínicos randomizados e controlados / Eficacia y seguridad de los agentes biológicos en el tratamiento de la psoriasis moderada a severa: un metaanálisis de ensayos aleatorios y controlados

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.

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.

Se realizó una revisión sistemática y metaanálisis de ensayos controlados aleatorios en pacientes con psoriasis moderada a severa tratados con biológicos o placebo por 10-14 semanas. 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.

Economic evaluation of treatments for chronic hepatitis B

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.

Análise das intervenções de farmacêuticos clínicos em um hospital de ensino terciário do Brasil / Analysis of clinical pharmacist interventions in a tertiary teaching hospital in Brazil

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.

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.

Insulin analogues versus human insulin in type 1 diabetes: direct and indirect meta-analyses of efficacy and safety

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.

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.

Eficácia de antifúngicos tópicos em diferentes dermatomicoses: uma revisão sistemática com metanálise / Efficacy of topical antifungal drugs in different dermatomycoses: a systematic review with meta-analysis

OBJETIVO: Avaliar e comparar a eficácia dos antifúngicos tópicos empregados no tratamento de cada dermatomicose. MÉTODOS: Foi desenvolvida uma revisão sistemática de ensaios clínicos randomizados, publicados em português, espanhol ou inglês até julho de 2010, que comparassem o uso de antifúngicos azólicos e alilamínicos entre si ou com placebo, no tratamento de candidíase cutânea, e das tineas versicolor, pedis, cruris e corporis. Os desfechos de eficácia avaliados foram cura micológica ao final do tratamento e cura sustentada. RESULTADOS: Dos 4.424 estudos inicialmente identificados, 49 alcançaram os critérios de seleção, sendo incluídos nas metanálises. Os dados agrupados de eficácia demonstraram superioridade dos antifúngicos frente a placebo, independente da dermatomicose avaliada, com valores de odds ratio (OR) variando de 2,05 (IC 95% 1,18-3,54) a 67,53 (IC 95% 11,43-398,86). Alilaminas foram superiores aos azólicos apenas para o desfecho cura sustentada (OR 0,52 [IC 95% 0,31-0,89]). CONCLUSÃO: Há evidência consistente da superioridade dos antifúngicos com relação ao uso de placebo, não sendo mais justificável a realização de estudos controlados por placebo. Alilaminas mantêm a cura micológica por períodos mais extensos que fármacos azólicos. Dada a significativa diferença de custo entre as classes, recomenda-se a realização de análises farmacoeconômicas.

OBJECTIVE: To evaluate and compare the efficacy of topical antifungal drugs applied to the treatment of each dermatomycosis. METHODS: A systematic review of randomized clinical trials, published in Portuguese, Spanish and English until July 2010, which compared the use of azole and allylamine antifungal drugs among themselves and with placebo in the treatment of cutaneous candidiasis and T. versicolor, T. pedis, T. cruris and T. corporis was performed. The efficacy outcomes evaluated were mycological cure at the end of treatment and sustained cure. RESULTS: Of the 4,424 studies initially identified, 49 met the selection criteria and were included in the meta-analyses. The grouped efficacy data evidenced the superiority of antifungal drugs compared to placebo, regardless of the dermatomycosis under evaluation, with odds ratio values ranging from 2.05 (95% CI 1.18-3.54) to 67.53 (95% CI 11.43-398.86). Allylamines were better than azoles only for the outcome sustained cure (OR 0.52 [95% CI 0.31-0.89]). CONCLUSION: There is consistent evidence of the superiority of antifungal drugs over the use of placebo, and placebo-controlled studies are no longer justifiable. Allylamines maintain the mycological cure for longer periods compared to azole drugs. Given the significant cost difference among the classes, pharmacoeconomic analyses should be performed.

Perfil dos usuários de anticitocinas disponibilizadas pelo Sistema Único de Saúde no estado do Paraná para o tratamento da artrite reumatoide / Profile of users of anticytokines off ered by the health care system in the state of Paraná for the treatment of rheumatoid arthritis

INTRODUÇÃO: O tratamento da artrite reumatoide (AR) no âmbito do Sistema Único de Saúde (SUS) tem financiamento do Ministério da Saúde e cofinanciamento das Secretarias Estaduais. O Protocolo Clínico e Diretrizes Terapêuticas (PCDT) para o tratamento da AR descreve o esquema terapêutico para a patologia, inclusive com as anticitocinas adalimumabe, etanercepte ou infliximabe. OBJETIVO: Traçar o perfil dos usuários de anticitocinas, medicamentos biológicos cadastrados no Sistema de Informação do Componente Especializado da Assistência Farmacêutica, gerenciado pelo Centro de Medicamentos do Paraná. MÉTODOS: Foi realizado um estudo transversal tomando como referência o mês de março de 2010. Com base em dados de dispensação, foram coletadas informações relativas a idade, gênero, regional de saúde (RS), Código Internacional de Doenças (CID) e medicamento dispensado. Calculou-se também o custo mensal com anticitocinas para o SUS. RESULTADOS: No estado do Paraná foram encontrados 923 pacientes recebendo anticitocinas, dos quais 40 por cento recebiam adalimumabe, 44 por cento etanercepte e 16 por cento infliximabe, gerando um custo mensal de R$3.403.195,59. Com relação ao CID, 55 por cento dos indivíduos apresentavam CID M05.8, 27 por cento CID M06.0, 9 por cento CID M6.8, 8 por cento CID M5.0 e 1 por cento dos indivíduos apresentava os outros CIDs relacionados com a doença. As RS do Paraná com o maior número de indivíduos em tratamento com anticitocinas foram as de Ponta Grossa, Cornélio Procópio, Londrina, Cianorte, Maringá, Irati e Campo Mourão. CONCLUSÃO: Por meio deste estudo foi possível verificar a distribuição e o perfil dos usuários de anticitocinas para o tratamento da AR no Paraná no âmbito do SUS no mês de março de 2010.

INTRODUCTION: The Brazilian Unified Health Care System (SUS) offers treatment for patients with RA through federal funding (Ministry of Health) and state co-financing. The Clinical Protocol and Therapeutic Guidelines for the treatment of rheumatoid arthritis describe the therapeutic regimen for the disease, including the anticytokines adalimumab, etanercept or infliximab. OBJECTIVES: The aim of this study was to evaluate the profile of registered users of those anticytokines, biologics registered in the Information System of the Pharmaceutical Assistance Specialized Division, managed by the Paraná State Drug Center. METHODS: A cross-sectional study regarding data from March 2010 was conducted. Based on dispensation data, information regarding the following variables were collected: age; gender; regional health care centers; International Classification of Diseases (ICD); and drug dispensed. In addition, the monthly cost with anticytokines for the SUS was calculated. RESULTS: In the state of Paraná, 923 patients on anticytokines were identified, 40 percent, 44 percent and 16 percent of whom receiving adalimumab, etanercept and infliximab, respectively. This generated a monthly cost of R$3,403,195.59. Regarding the ICD, the distribution of patients was as follows: 55 percent had ICD M05.8; 27 percent, ICD M06.0; 9 percent, ICD M6.8; 8 percent, ICD M5.0; and 1 percent had other ICDs related to the disease. The regional health care centers of the state of Paraná with the largest number of patients on anticytokines were in the following municipalities: Ponta Grossa; Cornélio Procópio; Londrina; Cianorte; Maringá; Irati; and Campo Mourão. CONCLUSION: This study assessed the distribution and profile of users of anticytokines for the rheumatoid arthritis treatment covered by the SUS in the state of Paraná, in March 2010.

Efficacy, safety and tolerability of using abatacept for the treatment of rheumatoid arthritis

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.

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.

Análise de custo-utilidade do tratamento adjuvante de câncer de cólon estádio III (Dukes C) / Análisis coste-utilidad del tratamiento adyuvante del cáncer de colon enestádio III (Dukes C) / Cost-utility analysis in adjuvant treatment of colon cancer staging III (Dukes C)

Introdução: O aumento do repasse financeiro ao tratamento adjuvante de câncer de cólon estádio II nos hospitaisintegrantes do Sistema Único de Saúde permite a utilização de quimioterápicos anteriormente não empregados.Entretanto, não há estudos farmacoeconômicos que norteiem gestores quanto à escolha da terapia. Objetivo: Avaliar a relação custo-utilidade das terapias adjuvantes Fluorouracil/Leucovorin (5FU/LV, Mayo Clinic Regimen) versusCapecitabina e 5FU/LV versus Fluorouracil/Leucovorin/Oxaliplatina (FLO X) para câncer de cólon em estádio II na perspectiva de um hospital público no Brasil. Método: Dados de eficácia foram extraídos da literatura e custos a partir do Sistema de Informação Hospitalar da referida instituição. Utilizou-se uma modelagem de Markov com dez ciclos de seis meses com quatro estados de saúde: terapia com antineoplásico, livre de doença, recidiva e morte. A taxa de desconto aplicada foi de 5%. Os custos foram expressos em Real (R$) e o desfecho em meses de vida ajustados pelaqualidade (QAL M). Realizou-se análise de sensibilidade univariada. Resultados: Capecitabina e FLO X proporcionam0,33 e 1,75 QALM a mais que 5FU/LV, respectivamente. A comparação Capecitabina e 5FU/LV mostrou relaçãocusto-efetividade incremental (RCEI ) de R$13.585,64/QALM, enquanto a comparação FLO X e 5FU/LV RCEIde R$1.007,92/QALM. A análise de sensibilidade sugere resultados robustos. Conclusão: O custo de aquisição da Capecitabina inviabiliza o uso em pacientes com câncer de cólon estádio III na perspectiva avaliada. O custo incremental de FLO X está compreendido pelo repasse financeiro do SUS, favorecendo sua incorporação como terapia adjuvante de câncer de cólon estádio II pelo hospital aos indivíduos elegíveis para esse protocolo

Cost-effectiveness of telbivudine versus lamivudine for chronic hepatitis B

BACKGROUND AND AIM: Chronic hepatitis B is a highly prevalent disease worldwide, leading to serious consequences if not properly treated. Six treatment options for chronic hepatitis B are currently provided by the Brazilian public health system. Telbivudine is a nucleoside analogue that is neither included in the Brazilian clinical protocol nor in the therapeutic guidelines for chronic hepatitis B. OBJECTIVE: The aim of this study was to evaluate the cost-effectiveness of telbivudine for the viewpoint of the Brazilian public system, comparing it to lamivudine. METHODS: A Markov model was used to project lifetime complications and costs of treatment with lamivudine or telbivudine for chronic hepatitis B in both HBeAg-positive and HBeAg-negative patients. To evaluate disease progression, probabilities and utilities of virologic response, virologic resistance, compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, treatment, interruption of treatment, death and seroconversion were collected in systematic reviews. Costs were collected in DATASUS, ABC da Saúde and scientific literature. RESULTS: Higher rate of virologic response and seroconversion was obtained with telbivudine, and also higher values of quality adjusted life years. However lamivudine is associated with lower costs and also lower cost-effectiveness values. The incremental cost-effectiveness ratios for telbivudine, when compared with lamivudine, were US$ 30,575 and US$ 40,457, respectively for HBeAg-positive and HBeAg-negative patients. CONCLUSION: In chronic hepatitis B lamivudine is a more cost-effective or even cost-saving strategy when compared with telbivudine.

Avaliação econômica das anticitocinas adalimumabe, etanercepte e infliximabe no tratamento da artrite reumatoide no Estado do Paraná / Economic evaluation of anticitokines adalimumab, etanercept and infliximab for treatment of rheumatoid arthritis in Paraná State, Brazil

Este estudo objetivou realizar uma avaliação econômica das anticitocinas adalimumabe (ADA), etanercepte (ETA) e infliximabe (IFX) para o tratamento da artrite reumatoide no Estado do Paraná, sob a perspectiva do SUS. Os dados de eficácia e segurança dos tratamentos foram buscados na literatura, e os custos foram calculados com valores gastos pelo SUS para cada um dos tratamentos. Foi elaborado o modelo de Markov para obter a relação custo-efetividade de cada tratamento. A relação custo-efetividade incremental (ICER) comparado ao tratamento padrão também foi calculada para cada anticitocina. Análises de sensibilidade e taxas de desconto foram aplicadas. Na avaliação custo-efetividade, encontraram-se custos por QALY de R$ 511.633,00, R$ 437.486,00 e R$ 657.593,00 para ADA, ETA e IFX, respectivamente. O ICER por QALY foi R$ 628.124,00, R$ 509.974,00 e R$ 965.927,00 para ADA, ETA e IFX, respectivamente. Nas análises de sensibilidade, o ETA e o ADA apresentaram valores próximos. Cabe aos gestores públicos e aos médicos prescritores a escolha adequada para cada paciente, entre os tratamentos disponibilizados.

This study aimed to perform an economic evaluation of anticytokines adalimumab (ADA), etanercept (ETA) and infliximab (IFX) for the treatment of rheumatoid arthritis in the State of Parana, in Brazil, in the perspective of the Brazilian Unified Health System. Data on efficacy and safety of treatment were collected in literature, and costs were calculated on the amounts spent by the Government for each treatment. A Markov model was performed to get the cost-effectiveness of each treatment. The incremental cost-effectiveness relationship (ICER) compared to a standard treatment was also calculated for each anticytokine. Sensitivity analysis and discount rates were applied. In assessing cost-effectiveness we found the following values (cost at R$ per QALY): 511,633.00, 437,486.00 and 657,593.00 (respectively for ADA, ETA and IFX). The ICER (R$ per QALY) was 628,124.00, 509,974.00 and 965,927.00 (for ADA, ETA and IFX). In the sensitivity analysis, ETA and ADA showed similar values. It is for public managers and physicians the choice for each patient, among the treatments available.

Instrumentos para avaliação da farmacoterapia do idoso: uma revisão / Tools for assessing the pharmacotherapy of the elderly: a review

O envelhecimento é definido, no contexto cronológico, como sendo a partir de 60 anos nos países em desenvolvimento como o Brasil e a partir de 65 anos nos países desenvolvidos. Estudos mostram que, em termos absolutos, o Brasil será o 6º país com a maior população idosa do mundo até o ano de 2025. Este dado se torna preocupante quando se percebe que os profissionais da área da saúde não estão preparados para atender essa demanda. São os idosos as pessoas que possuem maior número de diagnósticos e de uso de medicamentos; assim, a possibilidade do surgimento de problemas relacionados aos medicamentos é superior quando comparada à de pessoas jovens. Portanto, há necessidade de profissionais com conhecimento sobre as alterações fisiológicas e farmacológicas que ocorrem nos idosos, bem como sobre o uso de medicamentos por este grupo, a fim de avaliar a terapia prescrita e, quando necessário, sugerir alterações para otimização do tratamento. O farmacêutico pode ser este profissional. Este artigo traz uma revisão de alguns instrumentos de avaliação da farmacoterapia do idoso e os disponibiliza para que os profissionais possam utilizá-los durante o processo de acompanhamento destes pacientes.
