A simple, specific, accurate and precise reverse phase high performance liquid chromatographic method was developed for the simultaneous estimation of olmesartan medoxomil and metoprolol succinate in tablet dosage form. A Phenomenex-C18, 5 mcm column 250 mm 4.6 mm in gradient mode, with mobile phase containing phosphate buffer, acetonitrile and methanol in proportion of 65:35 v/v, pH 5.5 adjusted with orthophosphoric acid were used. The flow rate was 1 mL/min, and effluent was monitored at 254 nm.The retention time of olmesartan medoxomil and metoprolol succinate were 8.02 and 5.36 min respectively, and the resolution factor was 9.0. Linearity range for olmesartan medoxomil and metoprolol succinate was 5-30 mcg mL-1 and 5-70 mcg mL-1 respectively. The proposed method is accurate, precise,specific and rapid for simultaneous estimation of olmesartan medoxomil and metoprolol succinate in tablet dosage form.

Objective: A combination of hydrocortisone and tetracycline as topical ophthalmic ointment is used for skin irritations, eye infections, inflammation, skin infections, acne, and rashes. The objective of the current work is to a simple, rapid, accurate, and precise, stability-indicating reverse-phase liquid chromatographic method was developed for the simultaneous estimation of hydrocortisone and tetracycline in bulk and pharmaceutical dosage form. Methods: The separation was carried out in Discovery C18 column (250 × 4.6 mm, 5 μm) using mobile phase ratio of water (pH 2.2 adjusted with orthophosphoric acid):acetonitrile (40:60 v/v) in an isocratic elution mode with a flow rate of 1.0 ml/min at detection wavelength of 244 nm. The injection volume was 10 μl and the column temperature was set at 30°C. Results: The retention time for hydrocortisone and tetracycline was found to be 2.214 ± 0.001 min and 3.497 ± 0.001 min, respectively. Calibration curves were linear (r2=0.999) at a concentration range of 2.5–15 mg/ml for both hydrocortisone and tetracycline. The percentage recoveries were found to be 99.13–99.67% for hydrocortisone and 99.39–99.61% for tetracycline. Relative standard deviation was found to be 0.3% for both the drugs. Limit of detection and limit of quantification values of hydrocortisone and tetracycline were found to be 0.09 μg/ml and 0.27 μg/ml and 0.17 μg/ml and 0.52 μg/ml, respectively. The drugs were subjected to various stress conditions and found no interference of degraded products peak at the retention times of analyte peaks. Conclusion: A rapid and accurate reverse-phase high-performance liquid chromatographic method was developed for simultaneous estimation of hydrocortisone and tetracycline, and the method was validated as per the International Council for Harmonization guidelines. Hence, the developed method can be successfully applied for the simultaneous estimation of hydrocortisone and tetracycline in bulk and ointment formulation.

A simple precise and rapid Reverse Phase High Performance Liquid Chromatographic (RP-HPLC) method has been developed for quantitative determination of Regorafenib in tablet dosage form. In this method Hypersil Gold (C18, 150mm× 4.6mm id, 3μ) column with mobile phase consisting of Trifluoroacetic acid (0.2% v/v) and Acetonitrile in the ratio of (50: 50 v/v) at 400C in an isocratic mode was used. The detection was carried out at 260 nm and 20μL injection volume was selected with the flow rate 1mL/min. The linearity range of Regorafenib shows concentration between 5-200 μg/mL. The regression coefficient obtained was 0.999. Retention time of Regorafenib was found to be 6.49 minutes. Acetonitrile and Water in the ratio of (3:1) was used as a diluent. The method was validated as per ICH guidelines and is simple, fast, accurate, precise and can be applied for routine quality control analysis of Regorafenib in tablet dosage form.

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.
