Simple, accurate, and reproducible UV spectrophotometric and HPLC method for simultaneous estimation of salbutamol (SAL) and prednisolone (PRE) was developed in the present work. The first developed method was Simultaneous equation method, wavelength selected are 227 nm for salbutamol and 244 nm for prednisolone respectively. Linearity was observed in concentration range of 6-20μg/ml for salbutamol as well as for prednisolone. Second developed method was RP-HPLC method using Thermo C18 column (4.6 mm i.d × 250 mm) and acetonitrile: 0.025M potassium dihydrogen orthophosphate buffer (pH adjusted to 3.5 with orthophosphoric acid) in the ratio of 30:70% v/v as mobile phase. For HPLC method, linearity was observed in the concentration range of 20-100μg/ml for salbutamol as well as for prednisolone and drugs was subjected to oxidation, hydrolysis, and heat to apply stress condition for degradation studies. Results of analysis were validated stastically and by recovery studies.
