RP-HPLC Estimation of Risperidone in Tablet Dosage Forms
A simple, specific, accurate, and precise reverse phase liquid chromatographic method was developed and validated for the estimation of risperidone in tablet dosage forms. A Phenomenex Gemini C-18, 5 mum column having 250x4.6 mm i.d. in isocratic mode, with mobile phase containing methanol: acetonitrile: 50 mM potassium dihydrogen orthophosphate (80:10:10 v/v) was used. The flow rate was 1.3 ml...
متن کاملDevelopment and Validation of Rp-hplc Method for Simultaneous Estimation of Risperidone and Trihexyphenidyl Hydrochloride in Tablet Dosage Forms
A binary mixture of Risperidone (RIS) and Trihexyphenidyl hydrochloride (THP) was determined using reversed-phase liquid chromatography method using methanol: acetonitrile: 0.05 M phosphate buffer (pH 3.7) (60:30:10, v/v/v) pumped at a flow rate of 1.0 ml/min. Quantification was achieved with ultraviolet detection at 230 nm over concentration ranges of 0.5-5.0 and 1.0-10.0 μg/ml; mean accuracie...
متن کاملSimultaneous RP-HPLC Estimation of Trifluoperazine Hydrochloride and Chlordiazepoxide in Tablet Dosage Forms
A binary mixture of trifluoperazine HCl and chlordiazepoxide was determined using reversed-phase liquid chromatography method using methanol:water (97:03, v/v) pumped at a flow rate of 1.0 ml/min. Quantification was achieved with ultraviolet detection at 262 nm over concentration ranges of 0.1-1 and 0.5-5 mug/ml; mean accuracies were 101.05+/-0.47 and 98.97+/-0.33 %, respectively. The method wa...
متن کاملRp-hplc Method for Quantitative Estimation of Olanzapine in Tablet Dosage Forms
A simple RP-HPLC method for the determination of olanzapine in pharmaceutical dosage forms. Numerous HPLC conditions were tested for determination of olanzapine. The best result was achieved by using Capcell pak C-18 (250×4.6mm) 5μm column and a mobile phase consisting of Acetonitrile: Water: Tri ethylamine (60:40:0.1 v/v/v), a flow rate of 1.0 ml/min with ultraviolet detection at 270nm. The re...
متن کاملDetermination of Venlafaxine and Modafinil in Individual Tablet Dosage Forms using Single RP-HPLC Method
Purpose: To develop a simple and selective isocratic method for the determination of venlafaxine and modafinil in tablet dosage forms. Methods: The compounds were analyzed on Waters symmetry C18 column (4.6 mm x 250 mm i.d, 5μm) using a mobile phase consisting of a mixture of ammonium acetate buffer (pH was adjusted to 4.0 with glacial acetic acid):10 % methanol in acetonitrile, in the ratio of...
