A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.

A rapid, simple and highly sensitive reversed phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitative determination of Rabeprazole sodium and Aceclofenac in a combined dosage form. Rabeprazole sodium and Aceclofenac were chromatographed using C-18 column as stationary phase and methanol: acetonitrile: water (60 : 10 : 30 v/v/v) as the mobile phase at a flow rate of 1.0 ml/min at ambient temperature and detected at 280 nm. The retention time (RT) of Rabeprazole sodium and Aceclofenac were found to be 5.611 min and 2.102 minute, respectively. The linearities of Rabeprazole sodium and Aceclofenac were in the range of 1-10 µg/ml and 3-15 µg/ml, respectively. The limit of detection was found to be 0.091 µg/ml for Rabeprazole sodium and 0.043 µg/ml for Aceclofenac. The proposed method was applied for the determination of Rabeprazole sodium and Aceclofenac in a combined dosage form and result was found satisfactory.DOI: http://dx.doi.org/10.3329/icpj.v1i12.12450 International Current Pharmaceutical Journal 2012, 1(12): 410-413

A simple, rapid, economic, sensitive and precise HPLC method has been developed for the simultaneous determination of Sulphadoxine and Pyrimethamine in pharmaceutical dosage form by taking Tolterodine as an internal standard. The method was carried out using Phenomenex C18 (4.6ID × 250mm; 5µm) column and mobile phase comprised of methanol and Phosphate Buffer in proportion of ratio 60:40 v/v. The flow rate was 1.0mL/min and detection was carried out at 276nm. The retention time of Sulphadoxine, Pyrimethamine and Tolterodine were found to be 2.967, 4.058 and 6.908 respectively. Linearity of Sulphadoxine and Pyrimethamine in the range of 2 to 12μg/mL and 4 to 24μg/mL respectively. The % recoveries of Sulphadoxine and Pyrimethamine were found to be in between 99.93% to 99. 96 % respectively. The proposed method is suitable for the routine quality control analysis for simultaneous determination of Sulphadoxine and Pyrimethamine was in bulk and pharmaceutical dosage form.

Abstract An RP-HPLC method was validated for the determination of entecavir in tablet dosage form. The HPLC method was carried out on a Gemini C18 column (150 4.6 mm id) maintained at 30C. The mobile phase consisted of acetonitrilewater (95 + 5, v/v)/potassium phosphate buffer (0.01 M, pH 4; 9 + 91, v/v) pumped at a flow rate of 1.0 mL/min. Photodiode array detection was at 253 nm. The chromatographic separation was obtained with a retention time of 4.18 min, and the method was linear in the range of 0.5200 g/mL (r2 0.9998). The specificity and stability-indicating capability of the method was proven through forced degradation studies, which also showed that there was no interference of the excipients and an increase of the cytotoxicity only by the basic condition. The accuracy was 101.19, with bias lower than 1.81. The LOD and LOQ were 0.39 and 0.5 g/mL, respectively. Method validation demonstrated acceptable results for precision and robustness. The proposed method was applied for the analysis of tablet formulations, to improve QC and assure therapeutic efficacy.
