ABSTRACT
A simple & precise Stability indicating HPTLC method has been
developed & validated for the simultaneous estimation of Prasugrel
(PRA) & Aspirin (ASP) from Dosage form. The method employed
TLC aluminum plates precoated with silica gel 60 GF 254 as the
stationary phase. The solvent system comprised Carbon Tetrachloride:
Ethyl Acetate: Acetic Acid (7.5:2.4:0.1, v/v/v). This system was found
to give good result for both the drugs (Rf value: of ASP 0.34cm &
PRA 0.58cm).Spectrodensitometric scanning-integration was performed at a wavelength of
240nm.The calibration curve was found to be linear within the concentration range of
150ng/spot to 900ng/spot for PRA and1125-6750 ng/spot for ASP. The regression data for
calibration curve shows good linear relationship with r2 = 0. 9981 & 0.9979 for PRA & ASP
respectively. The method was validated as per ICH guidelines. Thus, the proposed method
can be used successfully for routine analysis of PRA & ASP from dosage form.
