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 simple and rapid reverse phase high performance liquid chromatography (RP-HPLC) method was developed and validated for quantitative determination of rabeprazole in bulk drug samples and formulations. Rabeprazole was analyzed by using reverse phase LC-GC column (Inertsil ODS, 4.6 mm x 25 cm, 5 microns), with mobile phase consisting of methanol: water (78:22 v/v). The flow rate was set 1.0 mL/min and analysis was performed at wavelength 288 nm using Photo Diode Array (PDA) detector at ambient temperature. The method was validated and stability studies were conducted under different conditions. The retention time for rabeprazole was around 4.12 minutes. The calibration curves were linear (r≥0.9998) over a concentration range from 20.0 to 80.0 μg/mL. Limit of detection (LOD) and Limit of quantitation (LOQ) were 8 ng/mL and 24 ng/mL respectively. The developed method was successfully applied to estimate the amount of rabeprazole in tablet formulations.

A simple and precise stability indicating RP-HPLC method was developed for the simultaneous estimation of acetyl cysteine and ambroxol hydrochloride in bulk and dosage form. Experimental design based evaluation using a 23 full factorial design was applied to evaluate coefficient, ANOVA for the establishment of robustness nature of the method. Kromosil (250 mm x 4.6 mm, 5 μ) C18 column at 274 nm of UV detection was used. A composition of 0.1 % ortho phosphoric acid and acetonitrile in the ratio of 28:72 (V:V) was used as the mobile phase with a flow rate of 1.0 mL min-1. Linearity was established over the concentration range of 50-300 μg. mL-1 for acetyl cysteine and 7.5-45 μg mL-1 for ambroxol hydrochloride. The proposed method was validated and was successfully utilized for the quantitative analysis of tablet formulations containing acetyl cysteine and ambroxol hydrochloride.

A simple, precise, and accurate isocratic RP-HPLC method was developed and validated for determination of Drotaverine hydrochloride (DROT) and paracetamol (PCM) in bulk drug and tablet formulations. Isocratic RP-HPLC separation was achieved on a Varian Microsorb mv C18 column (250 4.6 mm id, 5 mm particle size) using the mobile phase acetonitrile: water: triethylamine (TEA) (55:45:0.3%) with the pH adjusted to 3.5 and orthophosphoric acid at a flow rate of 1.6 ml/min. The retention time of DROT and PCM were 3.2713 and 1.5735 minutes, respectively. The detection was performed at 230 nm and samples of 20 µl were manually injected. The method was validated for linearity, precision, accuracy, robustness, and specificity. The method was found to be linear in the concentration range of 2-16 µg/ml with a correlation coefficient of 0.9997 for DROT and 12.5-100 µg/ml with a correlation coefficient of 0.9992 for PCM. The Calculated Limit of detection (LOD) and Limit of Quantitation (LOQ) for DROT were 0.0872 and 0.2644 µg/ml, respectively, and for PCM 0.2965 and 0.8984 µg/ml, respectively. The accuracy (recovery) was found to be in the range of 99.13%-101.52% with RSD of 1.194% for DROT and 99.09%-100.33% for PCM with RSD of 1.096%.
