A rapid and sensitive RP-HPLC Method with UV detection (283nm) for routine analysis of Tolterodine in Bulk and in Pharmaceutical formulation was developed. Chromatography was performed with mobile phase containing a mixture of Acetonitrile and 10mm Ammonium Acetate (80:20 v/v) with flow rate 1.0 ml/min. In the range of 20-100 µg/ml, the linearity of Tolterodine shows a correlation co-efficient of 0.999. The proposed method was validated by determining sensitivity, accuracy, precision, robustness, stability, specificity and selectivity.
