The objective of this experiment was to develop and validate a simple, robust, and accurate QbD based Reverse-Phase High-Performance Liquid Chromatography method for Simultaneous estimation of Amlodipine besylate and Lisinopril dihydrate in bulk and Pharmaceutical Dosage form. A box-Behnken design was employed for optimizing the mobile phase, flow rate and pH of buffer, the optimized chromatographic conditions were Phosphate buffer: Methanol (25: 75 v/v), pH of buffer: 6.5 and flow rate: 1mL/min. Furthermore formulation injected and observed that the additives do not interfere with the peak of Amlodipine besylate and Lisinopril dehydrate. Both drugs are well resolved and Retention times were found to be 2.332 min and 3.584 min respectively. Linearity was observed in the concentration range of 10 μg to 50 μg/mL (r2=0.999). The accuracy range was 99.75 to 100.04%. Intra-day and Inter-day precision was found to be less than 2% RSD. The proposed method was useful for the best analysis of Amlodipine besylate and Lisinopril dihydrate in Bulk, pharmaceutical dosage forms and was successfully applied to routine analysis.

The present study describes the stability indicating RP-HPLC method for simultaneous estimation of aliskiren hemifumarate and amlodipine besylate in pharmaceutical dosage forms. The proposed RP-HPLC method was developed by using waters 2695 separation module equipped with PDA detector and chromatographic separation was carried on C-8 Inertsil ODS (150 × 4.6 mm, 5 µ) column at a flow rate of 1 mL/min and the run time is 10 min. The mobile phase consisted of phosphate buffer and acetonitrile in the ratio of 40 : 60% v/v and pH was adjusted to 3 with orthophosphoric acid and eluents were scanned using PDA detector at 237 nm. The retention time of aliskiren and amlodipine was found to be 3.98 and 5.14 min, respectively. A linearity response was observed in the concentration range of 30–225 µg/mL for aliskiren and 2–15 µg/mL for amlodipine, respectively. Limit of detection and limit of quantification for aliskiren are 0.161 µg/mL and 0.489 µg/mL and for amlodipine are 0.133 µg/mL and 0.404 µg/mL, respectively. The stability indicating method was developed by subjecting the drugs to stress conditions such as acid and base hydrolysis, oxidation, and photo- and thermal degradation and the degraded products formed were resolved successfully from the samples.

A simple, rapid reverse phase high-performance liquid chromatographic method was developed and validated for the simultaneous estimation of Ezetimibe and Simvastatin in bulk and pharmaceutical dosage forms. Chromatography was carried out by using Chromosil C-18,column having 250 x 4.6mm internal diameter with a mixture of Methanol:Acetonitrile:0.1%Orthophosphoric Aid in the ratio of 75:20:05 (v/v/v) as mobile phase. Determination of the different analytical parameters such as linearity, precision, accuracy, and specificity, limit of detection (LOD) and limit of quantification (LOQ) was done. The calibration curve was found to be linear for each analyte in the desired concentration range. The average recovery was found to be 99.88 and 100.12 for Ezetimibe and Simvastatin respectively. The proposed method is highly sensitive, precise and accurate, which was evident from the LOD value of 1.2ppm and 0.25ppm for Ezetimibe and Simvastatin respectively and hence the present method can be applied successfully for the quantification of active pharmaceutical ingredient (API) content in the combined formulations of Ezetimibe and Simvastatin.

Ambroxol Hydrochloride

A simple, sensitive, accurate, precise and rapid stability indicating HPTLC method for simultaneous determination of ambroxol hydrochloride and Loratadine in pharmaceutical dosage form has been developed. The study was performed on TLC aluminum plates precoated with silica gel 60F254 using chloroform: methanol (9:1v/v) as the mobile phase. This system gives compact and dense spots for both ambroxol hydrochloride (Rf value of 0.36±0.003) and loratadine (Rf value of 0.68±0.002). Densitometric analysis of both drugs was carried out in the reflectance absorbance mode at 216 nm. The coefficient of correlation data for the calibration plots showed a good linear relationship with R2 = 0.997 ± 1.1224 in the range of 600-3600 ng for ambroxol hydrochloride and R2 = 0.998 ± 0.0935 in the range of 50-300 ng for loratadine. The method was validated according to ICH guidelines for specificity, precision, robustness and recovery. Stability study shows that the chromatograms of samples from its degradation products were well resolved with significant Rf value.
