The simple, selective, precise and accurate reverse-phase high-performance liquid chromatography method was developed and validated for analysis of tadalafil in bulk and tablet dosage form. The column was Inertsil C18 (150×4.6 mm; 5 μm) in isocratic mode. The mobile phase used was phosphate buffer (10 mM, pH 3.2) and acetonitrile (50:50% v/v) at the flow rate of 1.0 ml/min with ultraviolet detection at 295 nm at ambient temperature. The retention time for tadalafil was found to be 4.01 min. Linearity was observed in the concentration range from 60 to 140 μg/ml for tadalafil with a correlation coefficient of (r2 ) 0.9998. The method was validated according to International Conference on Harmonisation guidelines in terms of linearity, accuracy, precision and specificity. Hence, the proposed method can be utilized for routine quality control of tadalafil in bulk and tablet dosage form.
