Abstract
Present work describes a precise, accurate and reproducible RP-HPLC method for simultaneous estimation of salbutamol sulphate and guaifenesin. The drugs were resolved using a mobile phase of acetonitrile: 50 mM disodium hydrogen phosphate buffer containing 0.1% triethylamine (36:64 v/v pH 3.0) on an Inertsil, ODS-3V C18 (250 X 4.6 mm), 5μm column in isocratic mode. Recovery values of 99.82-101.07 %, percentage relative standard deviation of
