A qualidade de insumos farmacêuticos e medicamentos é uma questão imprescindível para o sucesso da terapêutica. Nesse sentido, a Agência Nacional de Vigilância Sanitária (ANVISA) têm, ao longo dos anos, estabelecido normas para regular os fornecedores de insumos, indústrias farmacêuticas e farmácias de manipulação e drogarias. Nesse sentido, o presente trabalho teve como objetivo avaliar a qualidade de cápsulas de guaraná (Paullinia cupana) manipuladas em farmácias de manipulação da cidade de Franca, São Paulo. A qualidade do produto foi avaliada seguindo métodos farmacopéicos como referência. As cápsulas foram avaliadas quanto à padrões mínimos de qualidade e envolveram a determinação do peso médio, umidade, material estranho, teor de cafeína, desintegração e cinzas. Os resultados demonstraram que o insumo foi adequadamente identificado, estando dentro dos padrões farmacopéicos de qualidade, no entanto, os resultados obtidos com o produto final demonstraram que 2% das amostras apresentaram avarias, como cápsulas amassadas, 30% demonstraram variação no peso acima da margem aceita. Desse modo, os resultados do trabalho sugerem que embora diversas medidas estejam sendo adotadas para a qualidade, há espaço para a implementação de melhoria contínua.

Background Compounds from vegetal matter have therapeutic potential to control highly prevalent microorganisms that are resistant to commonly used antimicrobial drugs. Dynamization of compounds can either maintain or improve their therapeutic effects, and make their use safer, especially those compounds whose therapeutic dose is close to the toxic limit. Aloysia polystachya (Griseb.) stands out among aromatic plants with antimicrobial potential. Objective The aim of this study was to evaluate the antimicrobial activity of dynamized and crude forms of A. polystachya essential oil against Candida albicans, Escherichia coli and Staphylococcus aureus. Methods Essential oil was extracted from A. polystachya dry leaves, solubilized, and dynamized at 1 cH potency as recommended by the Brazilian Homeopathic Pharmacopoeia. Antimicrobial activity against C. albicans, E. coli and S. aureus of the samples was assayed using the plate microdilution method. Results Dynamized A. polystachya essential oil at the concentration of 1 μg/mL inhibited the growth of all the microbial species analyzed. The minimum inhibitory concentration of dynamized essential oil was smaller than crude essential oil for S. aureus, E. coli and C. albicans. Conclusion It is reported for the first time that A. polystachya dynamized essential oil can effectively suppress microbial growth, and it is a promising adjuvant to treat infections with pathogenic S. aureus, E. coli and C. albicans.

Topical administration is a simple and comfortable form of cutaneous administration of drugs. However, in this route of administration the drug needs to overcome the barrier posed by the skin to reach an effective concentration. For this reason, many topical formulations are developed with a cationic component. The promotion of absorption occurs due to the disruption of the stratum corneum. But this cationic component has also high irritating potential to the skin. The biotherapics are medicines prepared from a toxic product or etiologic agent, following the homeopathic pharmacopoeia technique, and they are used mainly in cases of hipersensitization. In this experiment, high dilutions (HD) obtained from a cationic formulation were prepared and evaluated considering cell viability in “in vitro” mouse fibroblast (L929) culture cells model by a colorimetric MTT assay. No signs of toxicity were observed, which demonstrates the safety of these HD preparations to the healthy cells. The effectiveness of these HD was also investigated in cells damaged by cationic formulations. The results demonstrated that the HD 30c was the most effective preparation in preventing the cell damage caused by the tested irritating product, increasing cell viability from 56.6% (damaged cells) to 100% (similar to negative control group, p>0.05). These results provide evidence of the positive action of high dilutions against the exposure to a cytotoxic agent.
