Hplc Method Development

A new, economical, simple, accurate, and precise RP-HPLC method was developed for simultaneous assay and content uniformity determination of Sacubitril and Valsartan in bulk and pharmaceutical dosage form. The separation of Sacubitril and Valsartan was achieved within 6 minutes on Phenomenex Luna C18 250 mm x 4.6mm and 5µm Particle Size, column using Acetonitrile: Methanol: Water (30:55:15% v/v/v) as the mobile phase. Detection was carried out at 250 nm wavelength. The retention time of Sacubitril and Valsartan was found to be 2.361 and 3.304 min, respectively. The validation of the developed method was performed in terms of specificity, accuracy, precision, linearity, the limit of detection, the limit of quantification as mentioned in International Conference on Harmonization (ICH) guidelines. The method showed adequate sensitivity concerning linearity, accuracy, and precision over the range 12-36 μg/ml and 13-39 μg/ml for Sacubitril and Valsartan, respectively. The percentage recoveries obtained for Sacubitril and Valsartan were found to be in the range of 98.00 – 102.00 %. The proposed method is suitable for use in quality-control laboratories for quantitative analysis.

Aims: The main aim of the present study was to develop and validate a simple and cost- effective method for the estimation of allopurinol and its related substances by using RP-HPLC. Study Design:  Estimation of Allopurinol and its related substance in bulk and tablet dosage forms by RP-HPLC. Place and Duration of Study: Chalapathi Drug Testing Laboratory, Chalapathi Institute of Pharmaceutical Sciences, Chalapathi Nagar, Lam, Guntur-522034 between October 2020 to January 2021. Methodology: Method development was carried out by using Schimadzu, Prominence-i series LC 3D-Plus autosampler embedded with lab solutions software, equipped with PDA detector using YMC column (150 mm X 4.6 mm, 3 μm) and 0.1M Ammonium acetate buffer as a mobile phase in the ratio of 100% at a flow rate of 1.0 ml/min at a wavelength of 255nm. The developed method was validated according to ICH guidelines. Results:  The linearity was observed in the range of 20-100 µg/ml with a regression (R2) value of 0.999. Developed method was specific with no interactions and accurate with 100.11% for allopurinol and 99.54% for its related substance. The limit of detection for allopurinol was 2 µg/ml and for related substance was 0.0.1 µg/ml. The limit of quantification for allopurinol was 6 µg/ml and for related substance was 0.03 µg/ml respectively. The percentage relative standard deviation was found to be NMT 2 which indicates that the proposed method was precise and robust. Conclusion:  The developed method was simple, precise and accurate and can be successfully employed for the estimation of allopurinol in bulk and tablet dosage form.

Objective: A rapid, sensitive and specific reverse phase High performance liquid Chromatography (RP-HPLC) method was developed for the estimation of Fimasartan in bulk and pharmaceutical dosage form. Method: The RP-HPLC analysis was performed isocratically on a Primacel C18 column (150 mm × 4.6 mm internal diameter, 5 μm particle size) using mobile phase of composition Acetonitrile and 0.1% orthophosphoric Acid in 80:20, v/v proportions with a flow rate of 0.8 ml/min. Results: The analyte was monitered with UV-detector at 265 nm. In the developed method Fimasartan elutes at a typical retention time of 2.4 min. The proposed method is having linearity in the concentration ranging from 5-30 μg/ml of Fimasartan. Conclusion: : The method was statistically validated and had been applied to analysis of the drug in bulk and pharmaceutical dosage form.

Objective: A simple, accurate, precise, robust reverse phase high performance liquid chromatography (RP-HPLC) method was developed for the estimation of telmisartan and nebivolol hydrochloride (HCl) simultaneously in its combined dosage form.Methods: The compounds were well resolved in an isocratic method using the mobile phase composition of acetonitrile: Buffer (potassium dihydrogen orthophosphate pH adjusted 3.1 with orthophosphoric acid) in a ratio of 40:60 v/v at a flow rate of 1.2 ml/min using C18 Shim-pack (150 mm × 4.6 mm, 5 μ) column. The detection was carried out at 280 nm.Results: The retention time of telmisartan and nebivolol HCl was 4.8 min and 6.5 min, respectively. The developed method was validated by evaluating various validation parameters such as linearity, precision, accuracy, robustness, specificity, limit of detection, and limit of quantification according to the international council for harmonization guidelines. The standard calibration curve was obtained in the concentration range of 24–56 μg/ml for telmisartan and 3–7 μg/ml for nebivolol HCl. The overall average % recovery was found out to be 100.35 for telmisartan and 98.84 for nebivolol HCl.Conclusion: Statistical analysis of the data showed that the method is reproducible and selective for the estimation of telmisartan and nebivolol HCl. The proposed method could be used for analysis of telmisartan and nebivolol HCl in their dosage form.
