Abstract
A simple, fast and precise reverse phasehigh performance liquid chromatographic method developed for the simultaneousdetermination of risperidone and trihexyphenidyl hcl in its tablets form. C18 phenomenex Gemini column 250mm x 4.6mm (l x d)in isocratic mode with mobile phase buffer: Acetonitrile: methanol (50:30:20) %v/v were used. The flow rate was 1 ml/min. Linearity for risperidone andtrihexyphenidyl hcl were in the range of 96.96 mcg/ml – 145.44mcg/ml and 65.60mcg/ml – 98.4 mcg/ml respectively. Amount found of risperidone andtrihexyphenidyl hcl in sizodon plus was 3.034 mg/tab and 2.063 mg/tab respectively.Amount found of risperidone and trihexyphenidyl hcl in RI- plus was 3.016mg/tab and 2.044 mg/tab respectively. Percentage recoveries obtained forrisperidone and trihexyphenidyl hcl in sizodon plus were 100.87% and 102.49%respectively, percentage recoveries obtained for risperidone andtrihexyphenidyl hcl in RI-plus were 100% and 101.65% respectively. The proposed method is accurate, precise,selective and rapid for the simultaneous estimation of risperidone andtrihexyphenidyl hydrochloride in tablet dosage.
