ABSTRACT The purpose of the present study is to develop a new, simple, rapid, accurate and precise HPLC method for simultaneous estimation of Nebivolol Hydrochloride and Valsartan in tablet dosage form. The chromatographic separation was done by YMC Pack Pro C-18 (4.6mm*150mm, 3μm) column and a mobile phase was ACN: Methanol: KH2PO4 (30:30:40). detection wavelength was 279 nm, flow rate was 1.0 ml/min, injection volume was 20 μl, temperature of column was 30°C and auto sampler compartment was ambient. The retention time of Nebivolol Hydrochloride and Valsartan were found to be 3.62 min and 7.56 min, respectively. The method was found to be simple, accurate, economical, Precise and reproducible. There was no interference of any degradants and excipient in the determination of drugs in marketed formulation. So the method can be successfully applied for routine analysis.
