The aim of this study was to develop and validate a dissolution test for favipiravir release in a tablet dosage form using ultra-high performance liquid chromatography (UHPLC). The dissolution method was developed by testing the solubility of favipiravir in media with different pH values. The results demonstrated that the best dissolution was achieved in phosphate buffer with a pH of 6.8. The amount of favipiravir that was released was about 100% after 30 min. The UHPLC method presented linearity (R = 1.000) in the concentration range of 0.044–0.44 mg/mL. The recovery parameter that was achieved ranged from 102.5% to 104.2%. The system suitability, repeatability, and intermediate precision RSD% results were found to be 0.36%, 1.99%, and 2.49%, respectively. In addition to these parameters and results, an F-test was performed using the Minitab 18 Statistical Software program for the intermediate precision and repeatability results. The standard and sample solutions were found to be stable for 2 days in their respective dissolution medium. This analytical method was also found to be selective for favipiravir. In conclusion, a simple and feasible dissolution method with a short run time of 2.5 min was developed and validated successfully. The obtained results demonstrated that the dissolution test developed here is adequate for its purpose and can be applied as the dissolution method for favipiravir in film-coated tablets for release analyses.

A reversed-phase high-performance liquid chromatographic method was developed for the simultaneous determination of olmesartan medoxomil (OLME) and chlorthalidone (CHLOR) in tablet dosage form. The analysis was performed on Inertsil ODS C18 (250 x 4.6 mm, 5 μ) using KH2PO4 phosphate buffer (pH) and acetonitrile as mobile phase in the proportion of 60: 40 v/v at flow rate of 1.0 mL/min. Detection of drugs was carried out in isocratic mode using UV detector at 275 nm. The retention time of OLME and CHLOR was 13.9 ± 0.1 min. and 4.4 ± 0.5 min., respectively and the total run time was 20 min. The method was validated according to the requirements of the United States Pharmacopeia. The percentage recoveries was found to be in the range of 98.9 - 100.7%. The method was successfully applied to the assay of OLME and CHLOR in tablet dosage form.

Described in this manuscript is the first reported new, simple high performance thin layer chromatographic method for the determination of tapentadol hydrochloride in bulk and its tablet dosage form. The drug was separated on aluminum plates precoated with silica gel 60 F254 with butanol: water: glacial acetic acid in the ratio of 6:2:2 (v/v/v) as mobile phase. Quantitative analysis was performed by densitometric scanning at 254 nm. The method was validated for linearity, accuracy, precision and robustness. The calibration plot was linear over the range of 200-600 ng band -1 for tapentadol hydrochloride. The method was successfully applied to the analysis of drug in a pharmaceutical dosage form.

A reverse-phase high-performance liquid chromatography (RP-HPLC) method for the simultaneous estimation of Pyridoxamine dihydrochloride and Acetylcysteine in the marketed formulation is developed. Chromatography carried out at 30oc temperature on Agilent Zorbax Bonus-RP (250 x 4.6 mm, 5 µ) coloum. Coloum using a mobile phase 0.1% trifluroacetic acid in water: acetonitrile (80:20v/v) with flow rate 1ml/min (DAD scan at 210nm). Validation parameters such as system suitability, linearity, precision, accuracy are considered as reported International Conference on Harmonization guidelines. The retention times for Pyridoxamine dihydrochloride and Acetylcysteine are 2 min and 3.4 min. The linearity range for Pyridoxamine dihydrochloride and Acetylcysteine is 30-70 µg/ml and 180-420 µg/ml. The %RSD for accuracy was found to be less than 2%. Hence the proposed method was found to be accurate, precise, reproducible, and specific and can be used for simultaneous analysis of these drugs in tablet formulation.

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.
