Résumé
ABSTRACT OBJECTIVE To evaluate trends in the use of generic and non-generic medicines to treat hypertension and diabetes under the Farmácia Popular Program (FP) and its impact on generic medicines sales volume and market share in the Brazilian pharmaceutical market. METHODS This longitudinal, retrospective study used interrupted time series design to analyze changes in monthly sales volume and proportion of medicines sales (market share) for oral antidiabetic and antihypertensive medicines for generic versus non-generic products. Analyses were conducted in a combined dataset that aggregate monthly sales volumes from the Farmácia Popular program and from the QuintilesIMS™ (IQVIA) national market sales data from January 2007 to December 2012. The Farmácia Popular program phases analyzed included: a) 2009 reductions in medicines reference prices (AFP-II) and b) 2011 implementation of free medicines program for hypertension and diabetes, the Saúde não tem preço (SNTP - Health has no price). RESULTS Patterns of use for FP-covered antidiabetic and antihypertensive medicines were similar to their use in the market in general. After one year of the decreases in government subsidies in April 2010, market share of antidiabetic and antihypertensive medicines experienced relative declines of -54.5% and -59.9%, respectively. However, when FP-covered medicines were made free to patients, overall market volume for antidiabetic and antihypertensive generics increased dramatically, with 242.6% and 277.0% relative increases by February 2012, as well as non-generics with relative increase of 209.7% and 279% for antidiabetic and antihypertensive medicines, respectively. CONCLUSIONS Ministry of Health policies on the amount of patient cost sharing and on the choice of medicines on coverage lists have substantial impacts on overall generic sales volume in retail pharmacies.

Abstract This paper aims to analyse changes in the retail pharmaceutical market following policy changes in the Farmácia Popular Program (FP), a medicines subsidy program in Brazil. The retrospective longitudinal analyses focus on therapeutic class of agents acting on the renin-angiotensin system. Data obtained from QuintilesIMS (formerly IMS Health) included private retail pharmacy sales volume (pharmaceutical units) and sales values from 2002 to 2013. Analyses evaluated changes in market share following key FP policy changes. The therapeutic class was selected due to its relevance to hypertension treatment. Market share was analysed by therapeutic sub-classes and by individual company. Losartan as a single product accounted for the highest market share among angiotensin II antagonists. National companies had higher sales volume during the study period, while multinational companies had higher sales value. Changes in pharmaceutical market share coincided with the inclusion of specific products in the list of medicines covered by FP and with increases in or exemption from patient copayment.
Resumo Este artigo visa analisar as mudanças no mercado de varejo farmacêutico, seguindo as alterações de diretiva no Programa Farmácia Popular (FP), que realiza subvenção de medicamentos no Brasil, em parceria pública privada. Foi realizada análise longitudinal retrospectiva dos medicamentos da classe terapêutica dos agentes que atuam sobre o sistema renina-angiotensina. Os dados obtidos do QuintilesIMS incluíram o varejo farmacêutico em termos do volume e valores de vendas de 2002 a 2013. Análises realizadas consideraram intervenções e reformas ocorridas no FP e seu impacto no mercado farmacêutico da classe terapêutica selecionada, devido a sua relevância para o tratamento da hipertensão. Também se examinou o comportamento do mercado tomando por base as empresas farmacêuticas produtoras. Losartan monodroga representou a maior fatia de mercado entre os antagonistas de angiotensina II. Empresas nacionais obtiveram maior volume de vendas durante o período de estudo, enquanto as empresas multinacionais exibiram maior valor de vendas. Mudanças no mercado farmacêutico coincidiram com a inclusão de produtos específicos na lista de medicamentos abrangidos pelo FP e com aumentos ou isenção de copagamento pelos pacientes.

OBJECTIVE : To analyze the main predictors of access to medicines for persons who experienced acute health conditions. METHODS : This was a cross-sectional analytic study, based on data from household surveys. We examined the predictors of: (1) seeking care for acute illness in the formal health care system and (2) obtaining all medicines sought for the acute condition. RESULTS : The significant predictors of seeking health care for acute illnesses were urban geographic location, head of household with secondary school education or above, age under 15, severity of illness perceived by the respondent, and having health insurance. The most important predictor of obtaining full access to medicines was seeking care in the formal health care system. People who sought care in the formal system were three times more likely to receive all the medicines sought (OR 3.0, 95%CI 2.3;4.0). For those who sought care in the formal health system, the strongest predictors of full access to medicines were seeking care in the private sector, having secondary school education or above, and positive perceptions of quality of health care and medicines in public sector health facilities. For patients who did not seek care in the formal health system, full access to medicines was more likely in Honduras or Nicaragua than in Guatemala. Urban geographic location, higher economic status, and male gender were also significant predictors. CONCLUSIONS : A substantial part of the population in these three countries sought and obtained medicines outside of the formal health care system, which may compromise quality of care and pose a risk to patients. Determinants of full access to medicines inside and outside the formal health care system differ, and thus may require different strategies to improve access to medicines. .
OBJETIVO : Analisar os principais preditores de acesso a medicamentos em condições agudas de saúde. MÉTODOS : Estudo transversal analítico, baseado em inquérito domiciliar realizado em Nicarágua, Honduras e Guatemala. Foram identificados os preditores de: procurar cuidados para a condição aguda no sistema formal de saúde e obter todos os medicamentos procurados para a condição aguda. Os dados foram analisados com SPSS ® v.17, usando estatísticas descritivas e regressão logística multivariada. RESULTADOS : Houve autorrelato de doença aguda em 48,3% dos 2.761 domicílios pesquisados, sendo 59,0% em Nicarágua, 56,2% em Honduras e 30,9% na Guatemala. Indivíduos com doença aguda e pior percepção da gravidade da doença ou menores de 15 anos com seguro saúde tiveram maior chance de procurar cuidado. O acesso a medicamentos está fortemente correlacionado com a busca de cuidado, e a obtenção de todos os medicamentos necessários foi três vezes maior para aqueles que buscaram o sistema formal de saúde (OR 3,0; IC95% 2,3;4,0). Procurar o setor privado, ter alto nível educacional e percepção positiva sobre a qualidade do cuidado e dos medicamentos aumentam a chance de acesso pleno a medicamentos dentro do sistema de saúde. Para os pacientes que não procuraram o setor formal, o acesso pleno aos medicamentos foi mais provável em Honduras ou Nicarágua. Outros importantes preditores incluem localização urbana, maior status econômico e ser do sexo masculino. CONCLUSÕES : Parte da população nos três países obteve medicamentos fora do sistema formal de saúde, o que pode representar risco aos pacientes. Determinantes do acesso pleno a medicamentos, dentro e fora do sistema formal de saúde, foram distintos e assim ...

Objectives: To assess the possibility of bias due to the limited target list and geographic sampling of the World Health Organization (WHO)/Health Action International (HAI) Medicine Prices and Availability survey used in more than 70 rapid sample surveys since 2001. Methods: A survey was conducted in Peru in 2005 using an expanded sample of medicine outlets, including remote areas. Comprehensive data were gathered on medicines in three therapeutic classes to assess the adequacy of WHO/HAI's target medicines list and the focus on only two product versions. WHO/HAI median retail prices were compared with average wholesale prices from global pharmaceutical sales data supplier IMS Health. Results: No significant differences were found in overall availability or prices of target list medicines by retail location. The comprehensive survey of angiotensin-converting enzyme inhibitor, anti-diabetic, and anti-ulcer products revealed that some treatments not on the target list were costlier for patients and more likely to be unavailable, particularly in remote areas. WHO/HAI retail prices and IMS wholesale prices were strongly correlated for higher priced products, and weakly correlated for lower priced products (which had higher estimated retailer markups). Conclusions: The WHO/HAI survey approach strikes an appropriate balance between modest research costs and optimal information for policy. Focusing on commonly used medicines yields sufficient and valid results. Surveyors elsewhere should consider the limits of the survey data as well as any local circumstances, such as scarcity, that may call for extra field efforts.
Objetivos: Evaluar la posibilidad de sesgo debido a la limitación de la lista de referencia y del muestreo geográfico de la encuesta de precios y disponibilidad de medicamentos de la Organización Mundial de la Salud/Health Action International (OMS/HAI) usada en más de 70 muestras de encuestas rápidas desde el 2001. Métodos: En el año 2005, se realizó una encuesta en Perú, con una muestra ampliada de puntos de venta de medicamento, incluso en zonas remotas. Se recogieron datos integrales acerca de los medicamentos de tres clases terapéuticas, con el fin de evaluar la idoneidad de la lista de referencia de medicamentos de la OMS/HAI y el énfasis únicamente en dos versiones del producto. Las medianas de los precios al por menor de la OMS/HAI se compararon con el promedio de precios al por mayor del proveedor de datos mundiales de ventas farmacéuticas IMS Health. Resultados: No se observó ninguna diferencia significativa en la disponibilidad general ni en los precios de los medicamentos de la lista de referencia por localización de venta al por menor. La encuesta integral de los inhibidores de la enzima convertidora de la angiotensina, los antidiabéticos y los productos antiulcerosos reveló que algunos tratamientos que no están en la lista destinataria eran más caros para los pacientes y era más probable que no estuvieran a la venta, sobre todo en las regiones remotas. Los precios al por menor de la OMS/HAI y los precios al por mayor de IMS presentaron una correlación intensa en el caso de los productos de precio más alto, y la correlación fue débil en el caso de los productos de precio más bajo (que tuvieron márgenes de beneficio calculados más altos para el minorista). Conclusiones: El método de la encuesta de la OMS/HAI logra un equilibrio adecuado entre los costos de investigación moderados y la información óptima para la política. El énfasis en los medicamentos de uso frecuente produce unos resultados válidos y suficientes. Los encuestadores de otros...

Upper respiratory tract infections (URIs) are the most common infections worldwide. Their frequent inappropriate treatment with antibiotics is likely to increase antibiotic resistance, contribute to morbidity and mortality, and waste scarce resources. Using data from registration books and prescriptions, we measured patterns and assessed appropriateness and predictors of antibiotic prescribing for viral and bacterial URIs treated in health centers located in two slum communities in Bangkok, Thailand. Based on recorded diagnoses and symptoms, 91% of the patients probably had viral URIs; 60% of viral and 89% of bacterial URI patients were prescribed an antibiotic. Compliance with the national treatment guideline was 36.4% for treatment of viral URIs and only 1.7% for treatment of bacterial URIs. Amoxicillin was the most frequently prescribed antibiotic regardless of diagnosis. Among viral URI patients, those who were young, male, and self-paying were more likely to receive antibiotics; part-time physicians were more likely to prescribe antibiotics for these patients. Among patients with bacterial URIs, those who paid for drugs by themselves were more likely to receive antibiotics compared to patients covered by the national health insurance plan. We used these formative results as input to the design of health center and community interventions to encourage more appropriate prescribing for URI among adults.
