Simple, accurate, precise, sensitive and highly selective spectrophotometric methods were developed for the estimation of simvastatin. The estimation of simvastatin was carried out by various solvents like methanol (method I) at 236 nm, 2-propanol (method II) at 230nm and conc.H2SO4 (method III) at 415 nm. And these methods were found to be linear in the range of 1-6µg/ml, for method I and II and 10-60µg/ml for method III. And Beers law range were found to be 1-15µg/ml, 1-15µg/ml, and10-250µg/ml, and with mean recovery of 97.5 %, 97.5 % and 103.5 % of simvastatin for methods I, II and III respectively. The developed method was validated according to ICH guidelines and it found to be accurate and precise Thus the proposed method can be successfully applied for simultaneous determination of simvastatin and in routine analysis work.
