UV Spectrophotometric determination of Venlafaxine Hydrochloride was done by using Distilled water as a solvent to dissolve the drug(pure) with a known concentration (10 ug/ml). max was determined which showed maximum absorbance at 224 nm. It obeys Beer's Lambert's law by showing linearity at concentration range 2 - 14 ug/ml. By under going the analysis of formulation we concluded that it has maximum active ingredient in solid dosage form tablets of Venlafaxine Hydrochloride. The percentage purity of Venlafaxine Hydrochloride tablets was determined by performing assay and it was found to be...
