The present study describes the optimization and validation of a high-performance liquid chromatographic (HPLC) method for the determination of seven medicines (Metformin hydrochloride, Vildagliptin, Gliclazide, Sitagliptin phosphate, Pioglitazone hydrochloride, Glibenclamide and Glimepirde) in bulk and pharmaceutical dosage forms. The chromatographic separation could be achieved using a C8 column (100 Å, 5 µm, 150 mm) at 30 °C. Thereby, the mobile phase is a mixture of acetonitrile and an aqueous solution of triethylamine (0.5% v/v) and phosphoric acid 10% w/v (pH 7.0) at a mixing ratio of 32.5:67.5 v/v%, with a flow rate of 1.0 ml/min and detection performed at 210 nm using a UV detector. The results were found satisfactory and the method can be adapted to routine quality control of medications as recommended by the guidelines of the International Conference on Harmonization.

A novel approach was used to develop and validate a rapid, specific, accurate and precise Reverse phase High performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of Metformin and Sitagliptin in pharmaceutical dosage forms and its applications to dissolution study. The chromatographic separation was carried out on a C8 (250mm X 4.6 mm i.d., 5μm) column with a mobile phase of 40 Acetonitrile: 60 Phosphate Buffer (pH 6.8), using UV detector at 257 nm at 1ml min-1 flow rate. The retention time for Metformin was 2.11 minutes and 5.30 minutes for Sitagliptin. The Linearity for Metformin was found to be 10-80 µg ml-1 with R2 value of 0.9998 and for Sitagliptin 1-8 µg ml-1 with R2 value of 0.9976. Dissolution study of both for Metformin and Sitagliptin was carried, Percentage of drug release was established which was found to be 96.23% and 102.64% respectively, in the period of 50 minutes.

A high performance liquid chromatographic (HPLC) method with UV detector for the determination of dyclonine hydrochloride and a gas chromatography (GC) method with flame ionization detector (FID) for the determination of camphor and menthol in lotion were developed. The developed HPLC method involved using a SinoChoom ODS-BP C18reversed-phase column (5 μm, 4.6 mm × 200 mm) and mobile phase consisting of acetonitrile : water : triethylamine in a ratio of 45 : 55 : 1.0; pH was adjusted to 3.5 with glacial acetic acid. The developed GC method for determination of camphor and menthol involved using an Agilent 19091J-413 capillary chromatographic column (30 m × 320 μm × 0.25 μm). The two methods were validated according to official compendia guidelines. The calibration of dyclonine hydrochloride for HPLC method was linear over the range of 20–200 μg/mL. The retention time was found at 6.0 min for dyclonine hydrochloride. The calibration of camphor and menthol of GC method was linear over the range of 10–2000 μg/mL. The retention time was found at 2.9 min for camphor and 3.05 min for menthol. The proposed HPLC and GC methods were proved to be suitable for the determination of dyclonine hydrochloride, camphor, and menthol in lotion.

A simple, selective, linear, precise and accurate isocratic RP-HPLC method was developed and validated for rapid assay of Vandetanib, an anticancer drug, in both bulk and tablet dosage form. Elution at a flow rate of 1ml/min was employed on a symmetry C18 column at ambient temperature. The mobile phase consisted of acetonitrile, water and orthophosphoric acid in the ratio of 90:08:02 (v/v/v). Linearity was observed in concentration range of 50-200 ppm. The retention time for Vandetanib was 3.326 min. The method was validated as per the ICH guidelines. The proposed method can be successfully applied for the estimation of Vandetanib in pharmaceutical dosage forms. Moreover the detection alone was also verified through LC-MS of the Vandetanib drug using ESI method which provides future scope for study of this drug using LC-MS method also.
