Abstract:
A simple and rapid densitometric method has been developed for determination of tadalafil citrate in tablets and its dissolution media. After extracting the samples with acetone, the solutions were spotted onto pre‐coated silica gel TLC plates which were eluted with a mixture of n ‐hexane‐ethyl acetate‐methanol (8.0:6.0:2.0, v/v). quantitative evaluation was performed by measuring the absorbance reflectance of the tadalafil citrate spots at λ=285 nm. The TLC‐densitometric method is cheap, selective, precise, and accurate and can be used for routine analysis of tablets in pharmaceutical industry quality control laboratories.Keywords: Tadalafil citrate; Densitometry; Dissolution; Tablet; TLC; Validation
