A simple and sensitive RP-HPLC method for simultaneous estimation of Artesunate and Amodiaquine in combined tablet dosag

A simple, accurate, sensitive and validated RP-HPLC method for simultaneous determination of Artesunate and Amodiaquine in combined tablet dosage form has been developed. Separation was carried out on Jasco HPLC system equipped with Hypersil Gold C18 (250 × 4.6 mm i.d.) using mobile phase of Acetonitrile and 25 mM potassium dihydrogen phosphate buffer (70:30, v/v) at a flow rate of 1 ml/min using Artemether as internal standard and detection using UV/VIS detector was carried out at 220 nm. Ambient temperature conditions were maintained. Results were linear in the range of 250 – 2000 µg/mL for Artesunate and 10 – 30 µg/mL for Amodiaquine respectively. The method has been successfully applied for the analysis of drugs in pharmaceutical formulation. Results of analysis were validated statistically and by recovery studies.
