STABILITY INDICATING HPTLC METHOD FOR EFONIDIPINE Authors: Damle MC* And Bidkar S
ABSTRACT
Efonidipine is a drug used in the treatment of Hypertention. The literature survey did not reveal
any stability-indicating method for Efonidipine by high performance thin layer
chromatographic technique. Chromatographic separation was optimised for the Efonidipine
by using Ethyl acetate: Dichloromethane as a mobile phase in the ratio of 6:1(v/v). The
retardation factor was found to be 0.45 ±0.03. Detection wavelength was selected as 250 nm.
The linear range for analysis was 500-2500 ng/band which gives good linear relationship with
regression coefficient 0.999. The accuracy of the method was determined by the recovery
studies. The LOD and LOQ were 73.23 and 221.90 ng/band respectively. Stress degradation
conditions like hydrolysis under different pH conditions, photolytic degradation, thermal
degradation and oxidative degradation was performed as per ICH Q1A(R2) and Q1B
guidelines. This method can conveniently be used for quantitative analysis of Efonidipine on
routine basis.
