A modified RP-HPLC method was developed for the quantitative determination of recombinant human insulin in bulk and pharmaceutical dosage form with reduced retention time. Study of the effects of the column temperature, pH of the mobile phase and presence of vial additives (phenol andm-cresol), or impurities (A-21 Disamido) on the accuracy of the assay were assessed. Separation was achieved using a Hypersil BDS C-18 column and the mobile phase was composed of solution A (aqueous solution of 28.3 anhydrous Na2SO4g/L, pH 2.3) and solution B (28.5 g anhydrous Na2SO4g/L in 50:50 mixture of water and acetonitrile, pH 2.3) in a ratio 48:52 (v/v) at 45–50°C. The column temperature was 40°C, the flow rate was 1 mL/min and detection was performed at 216 nm. The procedures were validated according to international conference on harmonization (ICH) guidelines. Recovery study was done applying standard addition technique for further validation of the procedure. The retention time of recombinant human insulin was 19.7 min as compared to 29 min obtained by the reference method. Analytical conditions fluctuations or presence of vial additives or impurities did not show any significant effect on the accuracy of the method. The prepared standard insulin solution in 0.01 N HCl was found to be stable for 5 days. Statistical comparison showed no significant difference between the described method and reference method regarding the accuracy and precision. The modified method can be applied for routine quality control applications for determination of recombinant human insulin.

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 simple, selective, linear, precise, and accurate RP-HPLC method was developed and validated for rapid assay of Pizotifen in pharmaceutical dosage form. Isocratic elution at a flow rate of 1.0 mL/min was employed on Chromosil C18 (250 mm × 4.6 mm, 5 μm) column at ambient temperature. The mobile phase consists of methanol : acetonitrile in the ratio of 10 : 90 v/v. The UV detection wavelength was 230 nm, and 20 μL sample was injected. The retention time for Pizotifen was 2.019 min. The percent RSD for accuracy of the method was found to be 0.2603%. The method was validated as per the ICH guidelines. The method can be successfully applied for routine analysis of Pizotifen in the rapid and reliable determination of Pizotifen in pharmaceutical dosage form.
