Indinavir sulfate is a protease inhibitor in the cycle of the human immunodeficiency virus (HIV). The purpose of this study was the development of formulation, and its evaluation methodology for dissolution, rheological study, scale transposition, stability study and comparative study for indinavir sulfate 500 mg capsules (equivalent to 400 mg of indinavir). A qualitative design of diluents has been performed for the pharmaceutics development. The analytical methodologies for medium weight, disintegration, humidity and uniformity of weight followed The United States Pharmacopeia 28, while the methodology used for dissolution was developed and evaluated in accordance with Resolution RE nº 899, as of May 29, 2003, issued by the Agência Nacional de Vigilância Sanitária [National Agency for Sanitary Surveillance] (ANVISA). The results have evidenced that the selected formulation corresponds to the specifications of physical-chemical control, besides showing its economic feasibility. The results obtained from the development and evaluation of dissolution method have evidenced that the method complies with the requirements of Good Manufacturing and Control Practices, since it shows the reproducibility, the precision, the robustness and finally the reliability required for an analytical method. The developed indinavir sulfate capsules, when compared with the reference drug, are equivalent, in the light of different evaluated parameters.
