Abstract Background We describe a “stability-indicating liquid chromatography” technique for the estimation of dimethicone (DEC) and dicyclomine hydrochloride (DEH) in the established tablet formulations. Individual quantification of DEH and DEC was reported. But simultaneous quantification of DEH and DEC was lacking. DEH and DEC were analysed on an “XTerra C18 column (250 mm × 4.6 mm, 5 μm)” with the mobile phase solvent run isocratically with 0.1M K2HPO4-acetonitrile (55:45, v/v) on a flow speed of 1.0 mL/min. Results The chromatographic run period for the DEC and DEH assay was 6.0 min with retention times of 2.134 and 2.865 min, respectively. The method was validated for accuracy (99.453 to 100.417% and 99.703 to 100.303% recovery values for DEH and DEC, respectively), precision (RSV value 0.135% for DEC and 0.171% for DEH), linearity (5–15 μg/mL for DEH and 20–60 μg/mL for DEC), selectivity (no hinderance from excipients) and specificity (no hinderance from degradants) recovery. Conclusion The developed stability-indicating liquid chromatography process was well applied to established tablet formulations.

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. Keywords: RP-HPLC, Metformin, Sitagliptin, Dissolution study

A simple, accurate and reproducible RP-HPLC method has been developed for the simultaneous determination of lamivudine, zidovudine and abacavir in tablet dosage forms. Chromatography was carried out on a HiQ Sil C 18 V column using a mobile phase consisting of 0.01 M potassium dihydrogenortho-phosphate (pH 3.0) and methanol (55:45 v/v) at a flow rate of 0.8 mL/min. The detection was made at 272 nm and stavudine was used as the internal standard for this study. The retention times for lamivudine, abacavir and zidovudine were found to be 3.8, 6.3, 8.1 min. respectively. The calibration curves were linear over the range 5-250 μg/mL for both zidovudine and abacavir and 5-140 μg/mL for lamivudine. The proposed method was validated as per ICH and USP guidelines and it was found suitable for the routine quality control analysis of the drugs in tablet dosage forms.
