Spectrophotometric estimation of Nifidipine by using various solvents
A Simple and sensitive spectrophotometric method has been developed for the estimation of nifedipine in bulk and tablet formulation. The drug was determined by using various solvents like aqueous, organic and inorganic, which is determined spectrophotometrically at 281nm. The percentage recovery study of the drug for the proposed method range from 98-102% indicating no interference of the tablet excipients by using various solvents. The result obtained for percentage purity of nifidipine was dimethyl formamide and glacial acetic acid was only the solvents indicating the limit of recovery studies.
