RP-HPLC method was developed for the estimation of Lisinopril and Hydrochlorothiazide in tablet dosage form with the help of Quality by Design (QbD) approaches. In this method concentration of each drug was obtained by using the absorptivity values calculated for drug wavelength 226.0 nm and solving the equation. The RP-HPLC method was performed C18-(100mm x 4.6 mm,)2.5 μm particle size in gradient mode, and the sample was analysed using methanol 45.0 ml and 55.0 ml (pH 3.3 0.05% OPA with TEA) as a mobile phase at a flow rate of 0.8 ml/min and detection at nm. By the retention time for Lisinopril and Hydrochlorothiazide found 3.39 and 4.59 min respectively. Validation related the method is specific, rapid, accurate, precise, reliable, and reproducible. Calibration plots by both HPLC were linear over the 5-25 and 12.5-62.5 μg/ml for Lisinopril and Hydrochlorothiazide respectively, and recoveries from tablet dosage form were between 99.02 and 100.00 %.

The retention times were found to be 5.918 min and 14.901 min for AMLO and AZL, respectively. The proposed HPLC method was validated with respect to linearity, ranges, precision, accuracy, specificity, robustness, LOD, and LOQ as per ICH Q2 (R1) guideline. Calibration plots were linear over the concentration range of 75-125 µg/mL and 600-1000 µg/mL with correlation coefficients 0.9966 and 0.9948 for AMLO and AZL, respectively. Forced degradation studies were performed using hydrolysis, oxidation, photolytic, and thermal degradation conditions with good resolution between the degradants and analytes. Degradation products resulting from the stress studies did not interfere with the detection of AMLO and AZL, thus the proposed method is sensitive and stability-indicating. The validated HPLC method was successfully applied to the analysis of AMLO and AZL in tablet dosage form.

The current analytical exploration illustrated developing a reversed-phase high-performance liquid chromatography (RP-HPLC) technique and consequent substantiation for analyzing lamotrigine (LAM) active pharmaceutical ingredient (API) using a Quality-by-design (QbD) approach (Central Composite Design), in bulk product as well as in the tablet formulations. In this experiment, based on systematic scouting, four key components (viz., mobile phase, column, flow-rate, and wavelength) were studied by the RP-HPLC method. 13 experimental runs were done with acetonitrile (ACN) (40-60% v/v) having flow-rate in the range 0.8 mL/min to 1.2 mL/min. The proposed analytical method was thoroughly corroborated in terms of ruggedness linearity, robustness, accuracy, and precision in accordance with ICH guideline Q2A and ICH guideline Q2B. Under the optimum chromatographic environment; Intersil C8 column of 250 mm length, 4.6 mm (i.d.); 20 μL injection volume; and mobile phase ACN: Methanol (60:40 v/v), a retention time of 2.542 min was noticed at 220 nm detection wavelength. The method was found to be extremely reproducible, accurate, linear, precise, robust, and economically adequate to execute the estimation. The intended analytical technique was thoroughly assessed through statistical tools and could be an imperative concern for the habitual scrutiny of LAM in bulk products and its formulation.

Nowadays scientists aim at developing generic and specific methods for drugs in combined pharmaceutical dosage forms. The main aim was to develop and carry out validation using precision and accuracy for Sofosbuvir and Ledipasvir by applying RP-HPLC method. The dosage form in fixed combination of Sofosbuvir-Ledipasvir helps in effective treatment of genotypes of chronic hepatitis C virus. This combination of Sofosbuvir-Ledipasvir was the first FDA approved direct acting antiviral to treat hepatitis C. Both the drugs were optimized using mobile phase as acetonitrile: 0.1% orthophosphoric acid (55:50v/v) with pH 3.0. The mobile phase was optimized at maximum wavelength of 283nm. The separation was achieved using C18 Cosmosil (4.6 x 250mm) column with a particle size of 5µ. The method was specific eluting retention times of 3.7 for Sofosbuvir and 6.0 for Ledipasvir. Intra and interday precision was carried and %RSD was found to be less than 2%. The results were found to be accurate with percentage recovery of 99.76% and 99.10% for Sofosbuvir and Ledipasvir respectively. Linearity was carried out in the concentration ranging from 40-200µg/mL and 9-45µg/mL for Sofosbuvir and Ledipasvir respectively. Both the drugs showed the regression coefficient of 0.999. Deliberate changes in flow rate, pH and wavelength were made and found that method was robust. The developed method was found to be accurate, simple, specific, robust and precise for the simultaneous estimation of Sofosbuvir and Ledipasvir in tablet dosage form.
