Validação de método de dissolução com quantificação por HPLC de cápsulas de cloridrato de tramadol com e sem adição de enzima

Abstract

The present study approaches the validation of a high performance liquid chromatography quantification analytical method developed by a pharmaceutical company from western Paraná for the dissolution test of tramadol hydrochloride 50 mg capsules, in order to verify if the method presents selectivity, linearity, precision, accuracy and robustness, as established by Resolution 166 of July 24, 2017. The use of hydrochloric acid 0.1 M as dissolution medium was evaluated with and without the addition of the enzyme pepsin in order to solve the crosslinking problem observed in the gelatin capsules during the stability study. The proposed method has proved to be suitable for the laboratory conditions, satisfying all analytical requirements determined by the national regulatory agency, ANVISA, demonstrating that its use is possible for quality control purposes of the finished product.
