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.

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.

A Simple, selective, accurate, precise, linear, and stability-indicating RP-HPLC method was developed and validated for the estimation of Cinacalcet hydrochloride in bulk and tablet dosage forms. Chromatographic separation was achieved on X-Terra Symmetry C18 (4.6 x 150mm; 5 m) with mobile phase containing Phosphate buffer: Acetonitrile (40:60 v/v) pH adjusted to 3.0 ±0.05 with diluted ortho-phosphoric acid. The flow rate was maintained at 0.9 mL/min. The eluent was monitored at 282 nm. Moreover, the retention time of Cinacalcet was 2.8 minutes. The method was validated for linearity, accuracy, precision, and robustness as per ICH guidelines. The developed method was found linear between 25-150 μg/ml, and the linear regression coefficient was 0.999. The % RSD values are less than 2 % indicating the accuracy and precision of the method. The percentage of recovery was obtained from 98-102%. The system suitability parameters were found to be within the limit. Forced degradation studies were conducted under various conditions. The proposed method is simple, rapid, precise, and accurate. It can be used for the quantitation of Cinacalcet hydrochloride in bulk and commercial pharmaceutical dosage forms.

An improved stability-indicating RP-HPLC method was developed for the estimation of troxipide in bulk and tablet dosage forms. Chromatographic separation of troxipide from its degradation products was achieved on Agilent Zorbax SB-CN (150 × 4.6 mm, 3.5 μm) using sodium phosphate buffer (pH was adjusted to 4.0 ±0.05) and acetonitrile in the ratio of 40:60 V/V, at a flow rate of 0.8 mL/min. This system was found to give compact peak for troxipide at 2.1±0.2 min. The detection was monitored at 260 nm. The linear regression data for the calibration plots showed good relationship with r2 = 0.99 ± 0.001. The method was validated for precision, linearity, accuracy and robustness according to International Conference on Harmonization (ICH) guidelines. The percentage RSD was found to be less than two, indicating high degree of accuracy and precision of the proposed RP-HPLC method. The drug was subjected to stress degradation studies under acidic, basic, oxidative and thermal conditions. The degradation studies reveal that purity angle was less than the purity threshold, so the peak was said to be pure. It means that products resulting from stress studies did not interfere with the detection of troxipide and the assay can thus be considered as stability-indicating. Due to its simplicity, rapidness, high precision and accuracy, the proposed HPLC method may be used for determining troxipide in bulk and in pharmaceutical dosage forms.

A stability indicating RP HPLC method has been developed for the determination of gemcitabine hydrochloride. Chromatography was carried out on an ODS C18column (250×4.6 mm; 5μ) using a mixture of methanol and phosphate buffer (40: 60 v/v ) as the mobile phase at a flow rate of 1.0 mL/min. The detection of the drug was monitored at 270 nm. The retention time of the drug was found to be 2.31 min. The method produced linear responses in the concentration range of 10 to 60 μg/mL of gemcitabine HCl. The method was found to be reproducible for analysis of the drug in injectable dosage forms. The stability of the drug was assessed by forced degradation studies.
