[Abstract]:Objective to investigate the dissolution of Cefalexin trimethoprim capsules and evaluate the quality of Cefalexyl trimethoprim capsules in different drug manufacturers in China and discuss the reasonableness of dissolution test method. Methods using paddle method (rotational speed 50r/min), pH1.2 hydrochloric acid solution, pH4.0 acetate buffer solution, pH6.8 phosphate buffer solution and water as dissolution medium, respectively. The dissolution curves of cefalexin in cefalexin capsules were drawn. Results the dissolution curves of the products of only 5 out of 12 enterprises were similar to those of the cefalexin capsule reference preparation in Japanese orange peel book. The degree of differentiation of the product with water as dissolution medium is better than that of 0.1mol/L hydrochloric acid solution. Conclusion there are significant differences in dissolution of cefalexin trimethoprim capsules between different enterprises, the product quality needs to be improved, and the dissolution method needs to be improved.
