DEVELOPMENT AND VALIDATION OF STABILITY INDICATING ASSAY METHOD FOR DETERMINATION OF FELODIPINE IN TABLET DOSAGE FORM
Abstract
A simple and sensitive, HPTLC method has been developed for the quantitative estimation of felodipine in it’s single component tablet formulation. The separation was carried out on Merck aluminium plates precoated with silica Gel 60 F254 using n -hexane: ethyl acetate in the ratio of 6:4 (v/v) as mobile phase. Felodipine showed Rf value of 0.53 ± 0.027 and was scanned at 366 nm using Camag TLC Scanner 3. The linear regression data for the calibration plot showed a good relationship with r=0.9792. The method was validated for precision and recovery. The limits of detection and quantification were 23.54 and 71.33 ng/spot respectively. The developed method was successfully used for the assay of felodipine tablet formulations. The method is simple, sensitive and precise; it can be used for the routine quality control testing of marketed formulations.
