A novel stability indicating RP- HPLC method was developed for the estimation of Apremilast in bulk and marketed formulation. Separation was achieved by using Shimadzu HPLC Analytical Technologies Limited C18 (250 mm x 4.6 mm, 5µm) as stationary phase. The optimized mobile phase consist of potassium dihydrogen ortho phosphate (pH-3.2): acetonitrile in ratio of 40:60 %v/v with flow rate of 1mL/min by using methanol as diluent. Retention time of Apremilast was found to be 5.4 min which was estimated at wavelength 360nm. Linearity of Apremilast was observed in the concentration range of 50-400µg/mL with r² value of 0.9999. Assay of Apremilast tablet was found to be 99.14-100.75%. Stability indicating nature of RP- HPLC method was estimated by conducting degradation kinetic study. The forced degradation of Apremilast bulk indicate that degradation in acidic, alkali, oxidative and photolysis condition were found to be 21%, 6.5%, 25.7% and 3.9% respectively. The kinetic study of apremilast in alkali degradation followed first order kinetic study. The result indicate that the developed RP-HPLC method is suitable for estimation of Apremilast in presence of degradant product. The above method was validated as per ICH guideline.

A simple, accurate, reproducible and specific stability-indicating RP-HPLC method was developed for estimation of ethionamide in tablets. Ethionamide was exposed to acid, alkali and neutral hydrolysis at elevated temperatures, to thermolytic degradation, peroxide-mediated oxidation at room temperature in dark and to photolytic degradation. The drug was found stable to thermolytic and photolytic conditions and to neutral hydrolysis. However, substantial degradation was obtained in acid and alkali hydrolysis and complete degradation in peroxide-medicated oxidation. Similar degradation behavior was observed when ethionamide tablets were exposed to the mentioned forced degradation conditions. The method showed adequate resolution of drug from its potential degradation products on C18 (250 × 4.6 mm, 5µ) column using mobile phase of methanol: water (50: 50 % V/V) at 1 mL/min. The drug and its potential degradation products were detected at 290 nm. The method was validated as per the ICH Q2(R1) guidelines. The enrichment of the alkali degradation product was performed and isolated by preparative TLC and further confirmed by NMR and IR spectroscopy.

Simple and precise stability indicating RP-HPLC method for the quantitative determination of tizanidinehydrochloride (TZN) in pharmaceutical dosage form was developed and validated. The separation was achieved using Atlantis C18 column (250 x 4.6 mm, 5µm) at 25 °C using a mobile phase containing 20mM KH2 PO4 (pH 3.5):methanol in the ratio of 30:70 V/V at 0.8 mL/min flow rate and 315nm detection wavelength. The retention time for TZN was 3.7 min and showed linearity in the 5-40µg/mL range with R2 >0.99. The drug was subjected to acid/ base hydrolysis, oxidative and thermal degradation to establish stability indicating method. The method was validated as per ICHQ2 (R1) guidelines. The method was accurate, precise, and specific for TZN estimation. In stress studies, the drug was found to be stable to acid/alkaline hydrolysis, oxidation, and thermal degradation conditions.

The present paper describes the development of quick stability indicating RP-HPLC method for the simultaneous estimation of codeine phosphate and chlorpheniramine maleate in the presence of its degradation products, generated from forced degradation studies. The developed method separates codeine phosphate and chlorpheniramine maleate in impurities/degradation products. Codeine phosphate and chlorpheniramine maleate and their combination drug product were exposed to acid, base, oxidation, dry heat, and photolytic stress conditions, and the stressed samples were analysed by proposed method. The proposed HPLC method utilizes the Shimadzu HPLC system on a Phenomenex C18 column (, 5 μ) using a mixture of 1% o-phosphoric acid in water : acetonitrile : methanol (78 : 10 : 12) mobile phase with pH adjusted to 3.0 in an isocratic elution mode at a flow rate of 1 mL/min, at 23°C with a load of 20 μL. The detection was carried out at 254 nm. The retention time of codeine phosphate and chlorpheniramine maleate was found to be around 3.47 min and 9.45 min, respectively. The method has been validated with respect to linearity, robustness, precision, accuracy, limit of detection (LOD), and limit of quantification (LOQ). The developed validated stability indicating HPLC method was found to be simple, accurate, and reproducible for the determination of instability of these drugs in bulk and commercial products.

A simple, rapid and accurate and stability indicating RP-HPLC method was developed for the determination of valsartan in pure and tablet forms. The method showed a linear response for concentrations in the range of 50-175 µg/mL using 0.01 M NH4H2PO4(pH 3.5) buffer: methanol [50:50] as the mobile phase with detection at 210 nm and a flow rate of 1 mL/min and retention time 11.041 min. The method was statistically validated for accuracy, precision, linearity, ruggedness, robustness, forced degradation, solution stability and selectivity. Quantitative and recovery studies of the dosage form were also carried out and analyzed; the % RSD from recovery studies was found to be less than 1. Due to simplicity, rapidity and accuracy of the method, we believe that the method will be useful for routine quality control analysis.
