ABSTRACT
Literature survey reveals that there are no analytical methods were reported for the estimation of Udenafil by UV method. Hence the present study aims in developing simple, rapid, precise and validated methods for Udenafil in bulk. The methods are Colorimetric determination of Udenafil by Visible Spectrophotometric method, Validation of Udenafil by Visible Spectrophotometric method. The suitable solvent selected for performing estimation of Udenafil by UV spectroscopic method development and validation and fixed the λmax for the drug Udenafil. The present study successfully estimated the Udenafil from the formulation and performed validation studies of the drug Udenafil.
 

Key words: Udenafil, UV spectroscopic method, validation studies.
