Desenvolvimento e validação de método analítico para determinação simultânea de lamivudina, zidovudina e nevirapina em comprimidos dose-fixa combinada por cromatografia líquida de alta eficiência

Abstract: method has been developed and validated for the quantitation of lamivudine, zidovudine and nevirapine in the fixed-dose combination film-coated tablet by high performance liquid chromatography, in accordance with RE No. 899/2003, National Sanitary Surveillance Agency. It was based on an isocratic elution system with a potassium phosphate buffer pH 3.0: acetonitrile (60:40 v/v) mobile phase, C18, 250 x 46 mm column, 10μm particle size, λ 270 nm. The statistically evaluated results have shown that the method is … Show more

“…In the scientific literature, some works can be found describing the use of HPLC and UVVis spectroscopy for the quantification of these drugs in pharmaceutical formulations [5][6][7][8][9][10][11][12]. These methods, however, are expensive, laborious, consume a considerable amount of reagent, and require many analytical manipulations.…”
