Automedicación y autoprescripción / Self-medication and self-prescription

Resumen La automedicación y la autoprescripción son acciones de los pacientes; la primera como elemento del autocuidado que involucra medicamentos de venta libre y la segunda como una violación a la ley de salud, pues comprende medicamentos que solo pueden expenderse con receta. Todos los inconvenientes que se han atribuido a la automedicación en realidad lo son de la autoprescripción.

Abstract Self-medication and self-prescription are actions undertaken by patients; the former, as an element of self-care that involves over-the-counter drugs, and the latter, as a violation of the Statute of Health, since it includes drugs that can only be dispensed with a medical prescription. All the drawbacks that have been attributed to self-medication are actually associated with self-prescription.

Why deprescribing instead of not prescribing? / Por que desprescrever em vez de não prescrever?

Prescribing medications involves complex cognitive processes, and mistakes in prescription can cause serious adverse events. Deprescribing is one of the last opportunities to prevent patient harm from the use of drugs that should be avoided, especially among older patients. This viewpoint article aims to discuss the prescription process and some essential concepts, such as polypharmacy, prescription of potentially inappropriate medications, and, particularly, the relevance of deprescribing and its relationship with the appropriate prescription of medications in older people.

A prescrição de medicamentos envolve processos cognitivos complexos e erros na prescrição podem causar eventos adversos graves. A desprescrição é uma das últimas oportunidades de prevenir danos ao paciente decorrentes do uso de medicamentos que devem ser evitados, principalmente entre pacientes mais velhos. Este artigo teve como objetivo discutir o processo de prescrição e alguns conceitos essenciais, como a polifarmácia, a prescrição de medicamentos potencialmente inadequados e, particularmente, a relevância da desprescrição e sua relação com a prescrição adequada de medicamentos em idosos.

Interações medicamentosas potenciais em adultos e idosos na atenção primária / Potential drug interactions in adults and the elderly in primary health care

Resumo O objetivo do presente estudo foi caracterizar as interações medicamentosas potenciais (IMP) e avaliar os fatores associados à sua ocorrência em adultos e idosos assistidos pelo Programa Médico de Família de Niterói, Rio de Janeiro. Trata-se de um subestudo do ESTUDO DIGITALIS, que incluiu indivíduos cadastrados no Programa Médico de Família de Niterói (45-99 anos). Foram analisados 341 indivíduos com prescrição de dois ou mais medicamentos. A classificação das IMP seguiu o MICROMEDEX®. Houve 113 interações diferentes. Do total de indivíduos, 63,6% apresentaram pelo menos uma IMP. As variáveis com maior chance de IMP foram: menor escolaridade; renda inferior a R$800,00; ausência de plano de saúde; diagnóstico de hipertensão, diabetes, infarto agudo do miocárdio; e uso de 5 ou mais medicamentos prescritos. Após ajuste, as variáveis diagnóstico anterior de hipertensão e diabetes e uso de 5 ou mais medicamentos prescritos permaneceram significativas estatisticamente. É importante uma gestão cautelosa do tratamento na atenção básica com monitoramento das IMP, especialmente em pacientes mais susceptíveis.

Abstract The objective of the present study was to characterize the potential drug interactions (PDI), estimating the factors associated to their occurrence in adults and the elderly assisted by the Programa Médico de Família de Niterói, Rio de Janeiro. This is a sub-study of STUDY DIGITALIS, which included individuals enrolled in the Niteroi Family Medical Program (45-99 years). In this study, 341 individuals with a prescription of two or more drugs were analyzed. The classification of PDI followed MICROMEDEX. There were 113 different interactions. Of the total number of individuals, 63.6% had at least one PDI. The variables with higher probability of PDI were: lower level of schooling; income less than R$800.00; absence of health plan; previous diagnosis of hypertension and diabetes; use of 5 or more medications prescribed. After adjustment, the variables previous diagnosis of hypertension and diabetes and use of 5 or more prescription drugs remained statistically significant. Careful management of primary care treatment with monitoring is important in patients with PDI, especially in patients who are more susceptible.

An assessment of infant medication administration and storage practices in selected communities in the Vhembe District of Limpopo Province, South Africa

Background: Effective infant medication administration and storage is a major public health challenge outlined by the World Health Organization.These challenges may be exacerbated in rural or limited-resource areas.Aim: The aim of this study was to investigate infant medication administration and storage practices.Setting: This study took place in selected communities in the Vhembe District of Limpopo Province, South Africa.Method: Data was collected through 39 semi-structured interviews with infant caretakers and rural health workers. Interviews were recorded when permission was given by participants. Interviews were transcribed and coded using grounded theory and Tesch's model of data analysis. Themes were agreed upon through consensus discussions with the researchers and an independent coder. Results: Six themes that affect current infant medication administration and storage practices in the Vhembe District were identified: access to infant healthcare, the role of health workers, the devices used in the administration of infant medication, reluctance of the infant to take the medication, storage and reuse of infant medication in the rural home and hygiene practices surrounding infant medication administration.Conclusions: Many factors were found to affect infant medication administration and storage practices in in the Vhembe District. Substantial evidence was found to suggest that the relationship between rural health workers and infant caretakers strongly influences these practices: a great amount of reliance and trust is placed in the health worker. Ensuring proper dosage of infant medication in the rural household arose as a main concern of participants. Reuse of medication in the home and home hygiene practices surrounding infant medication administration are areas of potential future research. This future research may further inform recommendations for infant medication administration and storage practices in the Vhembe District

Nonbioequivalent prescription drug interchangeability, concerns on patient safety and drug market dynamics in Brazil / Intercambialidade de medicamentos não-bioequivalentes, segurança do paciente e dinâmica do mercado farmacêutico no Brasil

Abstract Since the enforcement of Generics Act (1999), three types of pharmaceutically equivalent products are marketed in Brazil: innovative reference (REF), "similar" (S) and generic (G) drugs. The S (brand name) and G (generic name) borrow from REF (brand name) clinical data on safety and efficacy and dosage regimen. G (but not S) is bioequivalent to and interchangeable with REF. Starting in 2003, Brazilian Sanitary Surveillance Agency (Anvisa) has required data on relative bioavailability tests (with REF) to approve (or renew registration of) S drugs. In 2014, Anvisa extended interchangeability notion to similar drugs with a "comparable" bioavailability, i.e., an "equivalent" similar drug (EQ). Drugs for chronic diseases and "critical dose medicines" are listed among the EQ drugs approved. Interchangeability of nonbioequivalent medicines raises deep concerns regarding therapeutic failures and adverse events. Concerns are even more worrisome if patients switch from one drug to another during an ongoing treatment for illnesses such as epilepsy, congestive heart failure, hypertension, diabetes and/or substitutable drugs have a narrow therapeutic index.

Resumo A partir da vigência da lei dos genéricos (1999), três tipos de produtos farmaceuticamente equivalentes são comercializados no Brasil: o medicamento inovador de refência (REF), o produto "similar" (S), e o genérico (G). O similar (nome de fantasia) e o genérico (nome genérico) tomam de empréstimo do REF (nome de fantasia) os dados clínicos de segurança e eficácia e a posologia. G (mas não S) é bioequivalente ao, e intercambiável com REF. Desde 2003, a Agência Nacional de Vigilância Sanitária (Anvisa) exige dados de testes de biodisponibilidade relativa para registrar (ou renovar o registro de) medicamentos S. Em 2014, a Anvisa estendeu o conceito de intercambialidade aos medicamentos similares com biodisponibilidade "comparável", i.e., um medicamento similar "equivalente" (EQ). Medicamentos para doenças crônicas e "fármacos de dose crítica" estão listados entre os produtos EQ aprovados. A intercambialidade de medicamentos não-bioequivalentes suscita grande preocupação quanto a falhas terapêuticas e eventos adversos. Os receios são ainda maiores se os pacientes trocam um medicamento por outro durante o tratamento de doenças como epilepsia, insuficiência cardíaca, hipertensão, diabetes e/ou os produtos farmacêuticos substituídos tem um índice terapêutico estreito.

Prescription medication by physiotherapists: a Brazilian view of the United Kingdom, Canada, Australia and New Zealand / Prescrição de medicamentos por fisioterapeutas: um olhar brasileiro sobre o Reino Unido, Canadá, Austrália e Nova Zelândia

Abstract Many health systems (HS) have adopted novel models of care which have included non-medical prescription (NMP) by physiotherapists. The aim of this study was to verify in the literature the existence of this practice and its possible benefits. A literature review was carried out through search on Science Direct, PubMed, SciELO, Lilacs and Google Scholar, and in the World Confederation for Physical Therapy and Chartered Society of Physiotherapy websites. In recent decades the United Kingdom adopted the NMP for health professionals, followed by Canada. In Australia and New Zealand physiotherapists have acted in the prescription and administration of medications under medical orders, which is the first step into independent prescription. Brazilian physiotherapists cannot prescribe any medication, despite of high demands from patients in the Brazilian HS, shortage of physicians in many regions and bureaucracy in accessing health services. The adoption of NMP by physiotherapists may play an important role in the HS, and it seems to be an inevitable achievement in the next years in Australia and New Zealand. The main benefits include decreasing bureaucracy for assistance, population demands for medication as well as major professional refinement.

Resumo Alguns sistemas de saúde (SS) têm adotado modelos inovadores de assistência que incluem a prescrição não médica (PNM) por fisioterapeutas. Este estudo objetivou verificar na literatura a existência dessa prática e seus possíveis benefícios. Foi realizada revisão da literatura, com buscas na Science Direct, PubMed, SciELO, Lilacs e Google Scholar, e nos sites da World Confederation for Physical Therapy e da Charthered Society of Physiotherapy, entre 2014 e 2015. O Reino Unido adotou a PNM por fisioterapeutas em décadas recentes, exemplo seguido pelo Canadá. Na Austrália e Nova Zelândia, fisioterapeutas têm atuado na prescrição e administração de medicamentos, sob ordens médicas, sendo este o primeiro passo para a prescrição independente. Fisioterapeutas brasileiros não podem prescrever medicamentos, apesar das altas demandas de pacientes, carência de médicos em muitas regiões e burocracia no acesso aos serviços de saúde. A prática da PNM por fisioterapeutas pode preencher um importante papel nos SS, e parece ser uma inevitável realização na Austrália e Nova Zelândia nos próximos anos. Os principais benefícios são a diminuição da burocracia no acesso a medicamentos e demandas populacionais, bem como maior refinamento profissional.

A contribuição do farmacêutico para a promoção do acesso e uso racional de medicamentos essenciais no SUS / Pharmacist's contribution to the promotion of access and rational use of essential medicines in SUS

Resumo O objetivo deste artigo é descrever o processo da inserção do farmacêutico na equipe de uma Unidade Básica de Saúde e os resultados na promoção do acesso e uso racional de medicamentos. Trata-se de estudo descritivo, transversal, realizado em unidade de atenção primária do município de São Paulo. As atividades do farmacêutico foram avaliadas em relação à estruturação e organização do serviço, melhoria do padrão de prescrição médica, elaboração de método de orientação e implantação de serviços farmacêuticos clínicos. A análise estatística foi realizada empregando o teste Qui-Quadrado de Pearson, com nível de significância de 5%, e o ODDs Ratio, quando comparados os períodos anterior e posterior à intervenções e resultados entre os anos de 2010 e 2011. A atuação do farmacêutico apresentou resultados estatisticamente significativos na redução da falta de medicamentos; melhora da qualidade da prescrição (com aumento do número de prescrições atendidas); redução do número de medicamentos prescritos entre os pacientes em seguimento farmacoterapêutico; e, comparando-se os anos 2010 e 2011, as recomendações de mudanças na farmacoterapia passaram a ter maior nível de aceitação. O farmacêutico contribuiu efetivamente para o acesso e a promoção do uso racional de medicamentos.

Abstract Objective: to describe the pharmaceutical inclusion process in a Basic Health Unit multidisciplinary team and evaluate results related to rational use and promotion of access to essential medicines. Methods: This is a descriptive, cross-sectional study conducted in a primary care health unit in the city of São Paulo. Pharmacist's activities were evaluated regarding the service structure and organization and prescribing quality improvement, guidance method creation, and implementation of clinical pharmacy service. Data measured before and after the interventions and between 2010 and 2011 were analyzed using Pearson´s chi-square test with a significance level of 5%, and odds ratio. Results: Pharmacist's activities had statistically significant result in drug shortage reduction; prescribing quality improvement associated with an increased proportion of prescriptions met; decrease in the total of prescribed drugs among patients receiving pharmacotherapeutic follow-up and, comparing the years 2010 and 2011, changes in the pharmacotherapy recommendations have gained increased acceptance level. Conclusions: Pharmacist's activities may effectively provide rational use and promotion of access to essential medicines.

Faut-il prescrire ou proscrire les médicaments chez la femme enceinte?

La prescription de médicaments au cours de la grossesse est très souvent une source d'inquiétude tant pour le professionnel de santé que pour la femme enceinte elle-même.La question du rapport bénéfice/risque pour la mère comme pour l'embryon ou le foetus ne semble pas toujours aussi évidente à résoudre et les mises en garde souvent non spécifiques des notices des médicaments peuvent apparaître difficiles à interpréter. C'est pourquoi, devant cette situation, plus que devant tout autre, l'expérience clinique et les connaissances pharmacologiques sont indispensables. Affirmer l'absolue innocuité d'un médicament est quasiment impossible, par contre il est facile, d'avoir une attitude prudente avec les médicaments récents et par conséquent mal évalués pour ne garder que les anciens, efficaces et reconnus pour leur faible tératogénicité ou toxicité. Le propos de cette revue est de fournir différentes informations précises et objectives permettant de faire un choix juste et raisonné de médicaments utilisables chez une femme enceinte

Avaliação da compreensão da farmacoterapia entre idosos atendidos na Atenção Primária à Saúde de Belo Horizonte, MG, Brasil / An evaluation of elderly people´s understanding of pharmacotherapy among those treated in the Primary Healthcare System in Belo Horizonte, Brazil

Resumo Os idosos apresentam maior número de doenças, levando a maior uso de medicamentos e a farmacoterapia mais complexa. O objetivo do estudo foi avaliar o nível de compreensão da farmacoterapia entre idosos e fatores associados. Realizou-se estudo transversal analítico em Unidades Básicas de Saúde. Foram investigadas as características sociodemográficas, clínicas, funcionais e relativas ao uso de medicamentos. O nível de compreensão foi obtido após a análise de concordância entre a resposta do entrevistado e a informação contida na prescrição para: nome do medicamento, dose, frequência, indicação, precauções e efeitos adversos. O nível global de compreensão foi classificado como insuficiente em caso de discordância ≥ 30%. Dos 227 idosos entrevistados, 51,1% apresentaram compreensão insuficiente em relação aos medicamentos. Realizou-se regressão logística multivariada para observar os fatores associados à compreensão da farmacoterapia, sendo menor escolaridade e dependência para uso dos medicamentos os que apresentaram associação com a compreensão insuficiente (p < 0,05). É necessário implementar estratégias para aumentar a qualidade das orientações fornecidas aos idosos e garantir seu cumprimento.

Abstract There are a greater number of elderly people with diseases which has led to a greater use in medication and complexity in pharmacotherapy. The aim of this study was to understand the level of understanding on pharmacotherapy amongst the elderly and associated factors. An analytical transversal study was carried out in the Primary Health Care Units. Sociodemographic, clinical, and functional characteristics relative to the use of medication were explored. The level of understanding was obtained after a concordance analysis had been done based on the responses from the interviewees and the information on the medical prescriptions such as: name of medication, dosage, frequency, indication, precautions and side effects. The global level of understanding was classified as insufficient in cases where the discordance was ≥ 30%. Of the 227 elderly people interviewed, 51.1% showed an insufficient understanding in relation to their medication. We carried out multivariate logistic regression to observe the factors associated with an understanding of pharmacotherapy. We noted that those with a low level of education and a dependency on the use of medication showed insufficient understanding. (p < 0,05). It is necessary to implement strategies to increase the quality of the guidance given to the elderly and to ensure compliance.

Características de las interacciones farmacológicas en una unidad de cuidados intensivos de pediatría / Characteristics of drug interactions in a pediatric intensive care unit

Introduction: The aim of this study is to calculate the theoretical frequency of potential drug interactions (PDI) and their characteristics in the therapeutic plan of hospitalized patients in a Pediatric Intensive Care Unit (PICU). Patients and Methods: An observational study was conducted which analyzed PICU prescriptions between September and November 2011. The inclusion criteria included to be hospitalized in a PICU, requirements of at least 3 drugs, except those topically applied, either gender, no age limit, no hospital stay required. The Micromedex ® 2.0 program was used to detect and classify PDI. Results: Of 223 patients, 100 met inclusion criteria, 610 prescriptions were analyzed and 815 drugs were prescribed. 1,240 PDI were detected in 44 patients; 12 patients received more than 10 drugs each, presenting 1,162 PDI (93.7% of total PDI). 8 patients were hospitalized for more than 10 days, presenting 1,035 PDI (83.5% of total PDI). According to PDI theoretical severity, 37.5% were high, 51.7% moderate, 6.7% low and 4.1% contraindicated. The therapeutic group most involved was antimicrobials (17.6%) and the most frequently involved individual drugs were chloral hydrate (15.9%), midazolam (14.1%) and vecuronium (13.4%). Conclusion: PDI were more frequent in patients associated with major polypharmacy and longer hospital stay.

Doce pacientes recibieron más de 10 fármacos cada uno, registrándose en ellos 1.162 IF (93,7% de las IF). Ocho pacientes estuvieron más de 10 días hospitalizados, concentrando 1.035 IF (83,5% de las IF). Según severidad teórica de las IF, se encontró 37,5% mayores, 51,7% moderadas, 6,7% menores y 4,1% contraindicadas. El grupo terapéutico más implicado fueron los antimicrobianos (17,6%) y los fármacos individuales más frecuentemente involucrados fueron hidrato de cloral (15,9%), midazolam (14,1%) y vecuronio (13,4%). Conclusión: Las IF fueron más frecuentes en pacientes con mayor polifarmacia y estadía más prolongada.

Propuesta metodológica para el funcionamiento de los Comités Farmacoterapéuticos en la Atención Primaria de Salud / Methodological proposal for the operation of Pharmacotherapy Committees in Primary Health Care

La OMS ha intensificado sus esfuerzos por promover y alcanzar un uso racional del medicamento para contribuir al bienestar del individuo y de la sociedad. El comité farmacoterapéutico es un foro para la mejora de la prestación de servicios de salud, es también un instrumento para fomentar un uso más eficaz y racional de los medicamentos. En Cuba se ha comprobado que existen problemas de uso irracional, lo que hace pensar que los comités farmacoterapéuticos no están funcionando según lo establecido. Objetivo: brindar una metodología a las instituciones de la Atención Primaria de Salud para el correcto funcionamiento del comité farmacoterapéutico. Método: se realizó una revisión exhaustiva de la literatura científica sobre los aspectos relacionados con cada apartado, se designó a un grupo multidisciplinario de profesionales expertos, procedentes de las áreas de Atención Primaria de Salud y Farmacoepidemiología con experiencia en el tema. El texto final estuvo sometido a comentarios y sugerencias, las recomendaciones fueron consensuadas por todo el grupo redactor. Resultados: se obtuvo un documento dirigido a los profesionales prescriptores y todos aquellos que realizan las tareas específicas de mejora de uso de medicamentos en las instituciones correspondientes a la Atención Primaria de Salud y a los gestores sanitarios que deben fomentarlas. La aplicación del mismo traerá como consecuencia beneficios médicos, económicos y sociales, una vez implantada la estrategia que estimulen e impulsen la actividad de dichos comité y así lograr un uso eficiente y racional de los medicamentos. Conclusiones: la metodología aportada por este documento hará que los CFT funcionen como foros de discusión para un uso adecuado, racional y seguro de los medicamentos...

The World Health Organization (WHO) has intensified its efforts to promote and achieve a rational use of medications to contribute to the individual and social welfare. The Pharmacotherapy Committee is a forum for improving health care services and is also considered an instrument to foster a more efficient and rational use of medication. In Cuba, it has been proven that there is an irrational use of medications, what makes us think that the Pharmacotherapy Committees are not functioning in accordance with the established. Objective: to provide a methodology to Primary Health Care institutions for the correct operation of the Pharmacotherapy Committee. Method: we conducted a detailed review of the scientific literature about the aspects related to each section and designed a multidisciplinary group of professional experts from Primary Health Care areas and Pharmacoepidemiology with experience on the topic. The final text was submitted to comments and suggestions and the recommendations were agreed by the consensus among the whole editor group. Results: we obtained a document which was directed to all professional prescribers and those that perform specific tasks for the improvement of the use of medications in Primary Health Care institutions as well as the sanitary managers that should encourage them. The application of this document will result in medical, economic and social benefits once the strategy has been implemented. These benefits should stimulate and promote the activities of such committees to achieve an efficient and rational use of medications. Conclusions: the methodology provided by this document will make the Pharmacotherapy Committees function as discussion forums for a safe, rational and adequate use of medications...

Uso de medicamentos off-label e não licenciados em unidade de tratamento intensivo neonatal e sua associação com escores de gravidade / Use of off-label and unlicensed drugs in the neonatal intensive care unit and its association with severity scores

OBJETIVO: Avaliar a frequência da prescrição de medicamentos de uso não licenciado (UL) e off-label (OL) em recém-nascidos internados em unidade de tratamento intensivo neonatal de hospital de nível terciário e verificar a associação do seu uso com a gravidade dos pacientes. MÉTODOS: Estudo observacional de coorte dos medicamentos prescritos no período de 6 semanas da internação de neonatos, entre julho e agosto de 2011. Os medicamentos foram classificados em UL e OL para dose, frequência, apresentação, faixa etária e indicação, de acordo com bulário eletrônico aprovado pela Food and Drug Administration. Os pacientes foram acompanhados até alta hospitalar ou 31 dias de internação, com registro diário do Neonatal Therapeutic Intervention Scoring System. RESULTADOS: Foram identificados 318 itens de prescrição para 61 pacientes (média de cinco itens/paciente) e apenas 13 pacientes com uso de medicamentos adequados (21%). Identificaram-se prevalências de 7,5% para prescrições UL e de 27,7% para OL. O uso OL mais prevalente foi para medicamentos não padronizados para faixa etária - 19,5%. Computaram-se 57 medicações - um paciente recebeu 10 fármacos UL/OL na internação. A prevalência de usos OL foi maior em prematuros < 35 semanas e nos com escores de gravidade mais elevados (p = 0,00). CONCLUSÕES: A prevalência de neonatos expostos a medicamentos UL/OL durante a internação hospitalar foi elevada, especialmente naqueles com maior escore de gravidade no Neonatal Therapeutic Intervention Scoring System. Embora haja apreciação geral de que neonatos, especialmente pré-termo, tenham alta taxa de uso de medicamentos, uma avaliação incluindo diferentes culturas e países é necessária para priorizar áreas de pesquisa futura na farmacoterapêutica dessa população vulnerável.

OBJECTIVE: To analyze the frequency of unlicensed (UL) and off-label (OL) prescriptions in neonates admitted to the neonatal intensive care unit of a tertiary care hospital and to determine their association with patients' severity. METHODS: Observational cohort study including drugs prescribed during hospitalization of neonates over a 6-week period between July and August 2011. The drugs were classified as UL and OL for dose, frequency, presentation, age group, or indication, according to an electronic list of drugs approved by the Food and Drug Administration. Patients were followed until hospital discharge or 31 days of hospitalization, with daily records of the Neonatal Therapeutic Intervention Scoring System (NTISS). RESULTS: We identified 318 prescription items for 61 patients (average of five items/patient); there were only 13 patients with appropriate use of medications (21%). A prevalence of 7.5% was identified for UL prescriptions and 27.7% for OL, and the most prevalent OL use was that related to age group - 19.5%. Fifty-seven medications were computed - one patient received 10 UL/OL drugs during hospitalization. The prevalence of OL uses was higher in preterm infants < 35 weeks and in those with higher severity scores (p = 0.00). CONCLUSIONS: The prevalence of neonates exposed to UL/OL drugs during hospitalization was high, especially for those with higher NTISS scores. Although there is general appreciation that neonates, especially preterm infants, have a high rate of drug use, an assessment including different cultures and countries is still needed to prioritize areas for future research in the pharmacotherapy of this vulnerable population.

Medicamentos prescritos aos idosos em uma capital do Sul do Brasil e a Relação Municipal de Medicamentos / Medicines prescribed to the elderly in a city in southern Brazil and the Municipal Medicines List

O objetivo deste trabalho foi descrever os medicamentos prescritos aos idosos residentes na zona urbana do Município de Florianópolis, Santa Catarina, Brasil, nos 30 dias anteriores à entrevista e, a partir disto, comparar com a Relação Municipal de Medicamentos (REMUME). Foi realizado um estudo transversal populacional de base domiciliar, no qual os 1.705 idosos entrevistados relataram ter utilizado o total de 5.458 medicamentos prescritos e dentro dos critérios da pesquisa, que corresponderam a 374 princípios ativos diferentes. Os medicamentos mais utilizados foram os indicados para o sistema cardiovascular, sendo a classe farmacológica dos redutores de colesterol e triglicerídeos os mais prevalentes, apesar de não haver nenhum exemplar desta classe de medicamentos selecionado na REMUME. Embora haja algumas faltas, a REMUME coincide com a maior proporção dos medicamentos prescritos no Município de Florianópolis. A principal diferença entre as prescrições é que as oriundas do SUS estão em maior conformidade com a REMUME.

The aim of this study was to describe the medicines prescribed to elderly residents of Florianópolis, Santa Catarina State, Brazil, in the 30 days prior to the interview, and to compare them with the Municipal Medicines List (REMUME). A cross-sectional population-based household survey was conducted, in which 1,705 elderly respondents reported having used a total of 5,458 prescription drugs meeting the study criteria and corresponding to 374 different active ingredients. The most frequently used medicines were for the cardiovascular system, among which the most prevalent pharmacological class was lipid-lowering drugs (although there were no examples of this drug class in the REMUME list). Despite some gaps, the majority of the drugs prescribed in Florianópolis coincided with the REMUME list. Prescriptions filled through the Unified National Health System were in greater conformity with the REMUME list.

Background: Osteoarthritis (OA) is a major cause of disability and is focused in "Bone and Joint Decade" declared by WHO which substantially affect different dimensions of quality of life. The aim of present study was to find the disease pattern in OA patients, monitoring prescription pattern to assess prognosis of osteoarthritis by WOMAC index. Materials and Methods: An observational study on prospective data collected for the evaluation of Quality of Life (QOL) in OA was conducted at tertiary health care centre in Mumbai. Patients with a diagnosis of OA were enrolled. The patient's history and clinical examination was based on classification criteria of the American College of Rheumatology; drugs prescribed were noted on case record form. Same procedure was carried out for the first and second follow-ups at 6 th and 12 th weeks respectively. Results: The patients belong to primary OA (84%) as compared to secondary OA (16%). Females (70.56% and 10%) were affected more commonly than males (13.44% and 6%). Knee Joint was worst affected in 76%, followed by hip joint in 16% and shoulder, ankle, wrist, elbow joint each having 2% (n=1) involvement. NSAIDs continued to dominate prescriptions given to 84% of patients followed by antiarthritic drugs and calcium supplements in 54% cases. The WOMAC score was higher in most of patients. After medication hydroxy chloroquine sulfate has shown maximum reduction in average WOMAC sore followed by paracetamol, indomethacin and diclofenac sodium. Conclusion: Osteoarthritis has a significant impact on quality of life, only partly ameliorated by anti-arthritic drugs, as assessed by the WOMAC scale in this study population. Further, a study with larger sample size is needed to further support our findings.

Perfil de utilización de medicamentos administrados por sonda enteral en el hospital universitario / Profile of the use of drugs administered via enteral feeding tube in a university hospital

The objective of this study was to evaluate the conditions of use of medicines in patients receiving enteral nutrition at units of University Hospital. The data collection was done using a structured questionnaire, based on patient's clinical files and observation of the nurse aides' routine in the period between January and April of 2009. Results demonstrated that 16.7 percent of the patients needed a feeding tube replacement because of obstructions. Approximately 52 percent of prescribed medicines were in solid form and at least eight medicines administered via feeding tube were recognized to be capable of drug-nutrient interaction in enteral feeding and affected at least one patient each. A conclusion can be drawn that there were prescription errors and inadequacy in techniques of administration of medicines to patients using probes of enteral nutrition.

El presente estudio tuvo como objetivo describir el perfil general de utilización de fármacos en pacientes que usan una sonda de nutrición enteral en un hospital universitario. La recolección de información fue hecha por medio de un formulario estructurado a partir de las fichas clínicas de pacientes internados en el hospital y de la observación de la rutina de los auxiliares de enfermería, en el periodo de enero a abril de 2009. Los resultados demuestran que 16,7 por ciento de los pacientes necesitaron cambio de catéter para nutrición enteral, debido a obstrucción. Aproximadamente 52,0 por ciento de los medicamentos prescritos estaban en la forma farmacéutica sólida y por lo menos ocho medicamentos administrados por sonda fueron reconocidos como capaces de provocar interacción fármaco-nutrición enteral, afectando por lo menos a un paciente. Se concluye que hay errores en la medicación y en las técnicas de administración de medicamentos para la sonda enteral.

Trends of home drug storage and use in different regions across the northern United Arab Emirates

To investigate the habits of use and home storage of over-the-counter [OTC] and prescription drugs. A pretested questionnaire was distributed to university students who represented 300 household units in different regions of the northern United Arab Emirates. Household chairs [parents] answered questions on various aspects of home use and storage of OTC and prescription medicines. The number of drugs stored at home was collapsed into 5 unequal groups [1-3, 4-6, 7-10, 11-15 and 16-20]. The response rate was 300 [100%]. The average number of drugs per household unit was 6 items. Almost 40% of the participants stored between 16 and 20 drugs. More than half [56%] of the household units stored medicines in a home pharmacy kept either in the bedroom [n=66; 39%] or in the kitchen [n=71; 42%]. No correlation was found between the level of education and the number of family members [r=0.29] or drugs stored at home [r=-0.35]. Only 2 [0.7%] of the participants did not keep drugs at home. There was a clear discrepancy in either OTC or prescription drugs stored, and the variation in the utilization and preference of drugs was obvious among the pooled sample. Various problems related to the use and storage at home of OTC and prescription drugs were revealed. Discussing the results of this survey with students who participated as members of the household units that took part in the study may prove to be a helpful intervention. The need for public educational efforts on the rational use of medicines at home is urgent to foster awareness of the proper use of drugs
