RESUMO
Apesar da atividade farmacológica de Mikania glomerata Spreng. ser conhecida desde longa data, existem poucos estudos visando a preparação de produtos padronizados que garantam uma produção uniforme, doses eficazes e estabilidade. Nesse trabalho, foram realizados ensaios objetivando a otimização do processo extrativo; tratamento da droga vegetal para o preparo de tinturas; determinação da melhor forma de estocagem e otimização da preparação da forma farmacêutica (xarope).
Although the pharmacological activity of Mikania glomerata Spreng. has been well known for a long time, there are a few studies concerning the elaboration of phytopharmaceutical products that assure an uniform preparation, effective doses and stability. In this work, tests with the objective of the optimization of the extraction process were performed; treatment of the plant drug for preparation of tinctures; determination of the adequate form of storage and the optimization of the preparation of the pharmaceutical form (syrup).
RESUMO
AIM: To achieve an optimum manufacturing process for acetaminophen extended release tablets. METHODS: To evaluate and set the manufacturing process according to the compressibility of the granule and the dissolubility of the finished tablets. RESULTS & CONCLUSION: The results showed that the bi-layer tablet technology was the most preferable pro- cess. The in vitro dissolution behavior and the in vivo bioavailability of the tablets are comparable to those of the imported products from McNEIL Consumer Healtheare Co. USA.
