【 摘 要 】

An analytical 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 specific, precise, accurate, and robust, ensuring the analytical safety of 3TC, AZT and NVP determination, which emerges as a new therapeutic alternative for antiretroviral treatment.
