ANALYTICAL METHOD DEVELOPMENT AND VALIDATION OF NIFEDIPINE IN FORMULATION BY RP-HPLC
Tejaswini*, Ch. M. M. Pradada Rao and D. Dhachinamoorthi
Abstract
The developed method was a simple, efficient, economical method for
the Validation of Nifedipine reverse phase high pressure liquid
chromatography and UV spectrophotometer. For Nifedipine Impurities
Chromatography was performed on Intersil C18-column (4.6×250mm,
5μm) with mobile phase TBH: Acetonitrile 25:75 (v/v) at a flow rate
of 1.0 mL/min and eluents were monitored at 238 nm The percent
recoveries ranged between 92.1 – 108.2 %,. RSD for all Parameters are
within the acceptance. The method could be successfully used for the
analysis Nifidepine in both API and Marketed tablet formulations.
Keywords: Nifidipine, TBH, Acetonitrile, Intersil, API.
