Controle de qualidade físico-químico e caracterização fitoquímica das principais plantas medicinais comercializadas na feira-livre de Lagarto-SE According to the World Health Organization (WHO), as medicinal plants contribute to health promotion, disease prevention, rehabilitation and healing. In this context, the present study sought to perform a physical -chemical and phytochemical characterization of the most commercialized medicinal plants in the free trade fair of Lagarto, municipality of Sergipe state. The most commercialized medicinal plants were Plectranthus barbatus Andrews 40%, Lippia alba (Mill.) N. E. Brown 25% and Pimpinella anisum L. 20%. It was possible groups of chemicals from the secondary metabolism of plants of each species studied in the absence of some groups described in the literature. Regarding the characterization phytochemical plant species Plectranthus barbatus Andrews was mostly within the standards set by the pharmacopoeia, but other medicinal plants are not yet standardized in the pharmacopoeia. The tests are vital for quality control, providing security for the users, and provide data for future studies to the standardization and development of new drugs.
A Hipertensão Arterial Sistêmica (HAS) é uma condição clínica multifatorial caracterizada por níveis elevados e sustentados da pressão arterial. Um dos mecanismos para controle da HAS é por meio do bloqueio dos receptores de angiotensina II (AII). A losartana potássica (LP), exemplo clássico de antagonistas dos receptores do subtipo AT1, é um dos fármacos mais utilizados para o tratamento da HAS. As formulações obtidas em farmácias magistrais devem apresentar qualidade suficiente para garantir a eficácia do tratamento e segurança do paciente. Diante do exposto, o objetivo deste trabalho foi avaliar a qualidade de cápsulas de LP manipuladas em três diferentes farmácias de Lagarto -SE. As cápsulas de LP (50 mg) foram obtidas em três diferentes farmácias (A, B e C) e os ensaios realizados foram: determinação de peso médio, desintegração e dissolução. Todas as cápsulas manipuladas foram aprovadas nos ensaios realizados, com exceção das cápsulas da farmácia B que foram reprovadas no teste de peso médio. Dessa forma, os resultados garantem uma boa credibilidade as farmácias magistrais, uma vez que, a maioria das amostras foram aprovadas de acordo com os critérios determinados pela farmacopeia brasileira ou pela referência adotada em determinada análise. Palavras-chave: Losartana potássica; Controle de qualidade; Farmácia magistralSystemic Arterial Hypertension (SAH) is a multifactorial clinical condition characterized by elevated and sustained blood pressure levels. One of the mechanisms to control hypertension is by blocking angiotensin II (AII) receptors. Losartan potassium (LP), a classic example of AT 1 subtype receptor antagonists, is one of the most widely used drugs for the treatment of SAH. Formulations obtained from manipulation pharmacies should be of sufficient quality to ensure the efficacy of the patient's treatment and safety. In view of the above, the objective of this work was to evaluate the quality of LP capsules handled in three different Lagarto-SE pharmacies. LP capsules (50 mg) were obtained from three different pharmacies (A, B and C) and the tests performed were: determination of mean weight, disintegration and dissolution. All capsules handled were approved in the performed tests, with exception of pharmacy B capsules, which were disapproved in the mean weight test. In this way, the results guarantee a good credibility to the manipulation pharmacies, since, the majority of the samples were approved according to the criteria determined by the Brazilian pharmacopoeia or by the reference adopted in the analysis. INTRODUÇÃOA hipertensão arterial sistêmica (HAS) é uma condição clínica multifatorial caracterizada pela elevação sustentada dos níveis pressóricos (≥ 140 e/ou 90 mmHg) [1]. Frequentemente, associase à distúrbios metabólicos, alterações funcionais e/ou estruturais de órgãos-alvo, sendo agravada pela presença de outros fatores de risco, tais como: dislipidemia, obesidade abdominal, intolerância à glicose e diabetes mellitus [1]. No Brasil, a HAS atinge 32,5% dos indivíduos adultos, 60% dos ...
