A simple, accurate, rapid and precise isocratic reversed phase high-performance liquid chromatographic method has been developed and validated for determination of Doravirine in tablets. The chromatographic separation was carried out on Dionex C18 (250 x 4.6mm, 5µ) with a mixture of methanol: 0.05M potassium dihydrogen phosphate (40:60%v/v) as a mobile phase at a flow rate of 1.5 mL/min. UV detection was performed at 306 nm. The retention time was 5.24 min for Doravirine. Calibration plot was linear (r2=0.999) over the concentration range of 200-600 µg/mL. The method was validated for accuracy, precision, specificity, linearity, robustness, LOD and LOQ. The proposed method was successfully used for quantitative analysis of tablets. No interference from any component of pharmaceutical dosage form was observed. Validation studies revealed that method is specific, rapid, reliable, and reproducible. The high recovery and low relative standard deviation confirm the suitability of the method for routine determination of Doravirine in bulk and tablet dosage form.

New Formulation

A rapid reversed-phase high performance liquid chromatography (RP-HPLC) method was developed for the determination of trans-resveratrol (t-RVT) in PLGA nanoparticle formulation. A new formulation of t-RVT loaded PLGA nanoparticles (NPs) with potential stealth properties was prepared by nanoprecipitation method in our laboratory. The desired chromatographic separation was achieved on a Phenomenex C18 column under isocratic conditions using UV detection at 306 nm. The optimized mobile phase consisted of a mixture of methanol: 10 mM potassium dihydrogen phosphate buffer (pH 6.8): acetonitrile (63 : 30 : 7, v/v/v) at a flow rate of 1 mL/min. The linear regression analysis for the calibration curves showed a good linear correlation over the concentration range of 0.025–2.0 μg/ml, with determination coefficients, R2, exceeding 0.9997. The method was shown to be specific, precise at the intraday and interday levels, as reflected by the relative standard deviation (RSD) values, lower than 5.0%, and accurate with bias not exceeding 15% and percentage recovery was found to be in the range between 94.5 and 101.2. The limits of detection and quantification were 0.002 and 0.007 μg/ml, respectively. The method was successfully applied for the determination of t-RVT encapsulation efficiency.

A rapid, simple and highly sensitive reversed phase high performance liquid chromatographic (RP-HPLC) method has been developed for the quantitative determination of Rabeprazole sodium and Aceclofenac in a combined dosage form. Rabeprazole sodium and Aceclofenac were chromatographed using C-18 column as stationary phase and methanol: acetonitrile: water (60 : 10 : 30 v/v/v) as the mobile phase at a flow rate of 1.0 ml/min at ambient temperature and detected at 280 nm. The retention time (RT) of Rabeprazole sodium and Aceclofenac were found to be 5.611 min and 2.102 minute, respectively. The linearities of Rabeprazole sodium and Aceclofenac were in the range of 1-10 µg/ml and 3-15 µg/ml, respectively. The limit of detection was found to be 0.091 µg/ml for Rabeprazole sodium and 0.043 µg/ml for Aceclofenac. The proposed method was applied for the determination of Rabeprazole sodium and Aceclofenac in a combined dosage form and result was found satisfactory.DOI: http://dx.doi.org/10.3329/icpj.v1i12.12450 International Current Pharmaceutical Journal 2012, 1(12): 410-413

Abstract A rapid, accurate, and sensitive high-performance liquid chromatographic (HPLC) method was developed and validated for the determination of ceftazidime in pharmaceuticals. The method validation parameters yielded good results and included range, linearity, precision, accuracy, specificity, and recovery. The excipients in the commercial powder for injection did not interfere with the assay. Reversed-phase chromatography was used for the HPLC separation on a Waters C18 (WAT 054275; Milford, MA) column with methanolwater (70 + 30, v/v) as the mobile phase pumped isocratically at a flow rate of 1.0 mL/min. The effluent was monitored at 245 nm. The calibration graph for ceftazidime was linear from 50.0 to 300.0 g/mL. The values for interday and intraday precision (relative standard deviation) were <1. The results obtained by the HPLC method were calculated statistically by analysis of variance. We concluded that the HPLC method is satisfactory for the determination of ceftazidime in the raw material and pharmaceuticals.

A high performance liquid chromatographic method for determination of rifabutin in human plasma was  developed. The method involved deproteinisation of the sample with acetonitrile and analysis of the  supernatant using a reversed-phase C18 column (250mm) and UV detection at a wavelength of 265nm.  The assay was specific for rifabutin and linear from 0.025 to 10.0μg/ml. The relative standard deviation  of intra- and inter-day assays was lower than 10%. The method was able to remove interfering materials  in plasma, yielding an average recovery of rifabutin from plasma of 101%. Due to its simplicity, the assay  can be used for pharmacokinetic studies of rifabutin.

A novel reversed phase ultra-high performance liquid chromatographic (RP-UHPLC) method was developed for the estimation of sitagliptin in pharmaceutical dosage form. Separation was done by a X-bridge C18 column (4.6 i.d.× 150 mm, 5 μm particle size) with a flow rate of 1 ml/min using phosphate buffer (pH 6) and acetonitrile (70:30, v/v) as mobile phase at 268 nm using photodiode array plus (PDA+) detector. The retention time was found at 4.607 min. The developed method was validated as per the requirements of ICH-Q2B guidelines for specificity, system suitability, linearity, precision, accuracy, sensitivity and robustness. The linear regression analysis data for the linearity plot showed correlation coefficient values of 0.999 with LOD value of 0.06 μg/ml and LOQ of 0.225 μg/ml. The relative standard deviation (%RSD) for inter-day and intra- day precision was not more than 2.0%. The method was found to be accurate with percentages recovery of 98.50±0.03 to 99.70±0.05 and the % RSD was less than 2. The results showed that the proposed method is highly convenient for routine analysis of sitagliptin.Dhaka Univ. J. Pharm. Sci. 17(1): 123-129, 2018 (June)
