Abstract (2. Language):
The aim of present work is to develop and validate simple, sensitive and
specific spectrophotometric method for the determination of Simvastatin, a
hypolipidemic drug in pure form and in pharmaceutical formulations. UV
spectrophotometric method, which is based on measurement of absorption
at maximum wavelength in solvent system employed for the determination
of simvastatin was methanol with 0.05% acetic acid, water with 0.03% w/v
of SLS, 1.2 pH with 0.03% w/v of SLS, phosphate buffer pH 6.8 and 7.4 pH
with 0.03% w/v of SLS, was found to be at 238 nm. The developed method
was validated with respect to linearity, accuracy (recovery), precision and
specificity. The optimum conditions for analysis of the drug were
established. The drug obeyed the Beer's law and showed good correlation.
Beer's law was obeyed in concentration range 0-16 u.g/ml. The results of
analysis were validated by recovery studies. The method was found to be
simple, accurate, precise, economical and robust. This method was
extended to formulation and there was no interference from excipients and
diluents. This method has been statistically validated and is found to be
precise and accurate.
Results obtained that are further used for the formulation development.
