Objective: The present work focused on developing a validated stability indicating RP-HPLC method for the estimation of pirfenidone in bulk drug and tablet dosage form. Methods: The chromatographic separation was performed on symmetry C18 (150 mm x 4.6, 5 micron) with a 1 ml/min flow rate at 315nm. The mobile phase employed was orthophosphoric acid buffer: acetonitrile (65:35). Column temperature was maintained at 30ºC. Pirfenidone was subjected to different forced degradation conditions according to ICH guidelines, including acid, base and neutral hydrolysis, oxidation, photolysis and thermal degradation.  Results: In alkali, acidic, oxidation and UV degradation conditions the drug shows considerable degradation. Pirfenidone was stable under neutral hydrolysis and thermal degradation. Pirfenidone was stable under extreme degradation conditions showing less than 8% of degradation in all degradation conditions. This result showed that pirfenidone was stable under stress degradation. Then the optimized method was validated for the parameters like linearity, accuracy, precision and robustness as per ICH guidelines.

Abstract An RP-HPLC method was validated for the determination of entecavir in tablet dosage form. The HPLC method was carried out on a Gemini C18 column (150 4.6 mm id) maintained at 30C. The mobile phase consisted of acetonitrilewater (95 + 5, v/v)/potassium phosphate buffer (0.01 M, pH 4; 9 + 91, v/v) pumped at a flow rate of 1.0 mL/min. Photodiode array detection was at 253 nm. The chromatographic separation was obtained with a retention time of 4.18 min, and the method was linear in the range of 0.5200 g/mL (r2 0.9998). The specificity and stability-indicating capability of the method was proven through forced degradation studies, which also showed that there was no interference of the excipients and an increase of the cytotoxicity only by the basic condition. The accuracy was 101.19, with bias lower than 1.81. The LOD and LOQ were 0.39 and 0.5 g/mL, respectively. Method validation demonstrated acceptable results for precision and robustness. The proposed method was applied for the analysis of tablet formulations, to improve QC and assure therapeutic efficacy.

The separation of EFX and its degradation products in tablets was carried out on Kromasil C-18(250×4.6 mm, 5 μm) column using 0.1% (v/v) TEA in 10 mM KH2PO4(pH 2.5) buffer and methanol by linear gradient program. Flow rate was 1.0 mL min−1with a column temperature of 35°C and detection wavelength was carried out at 278 nm and 254 nm. The forced degradation studies were performed on EFX tablets under acidic, basic, oxidation, thermal, humidity, and photolytic conditions. The degraded products were well resolved from the main active drug and also from known impurities within 65 minutes. The method was validated in terms of specificity, linearity, LOD, LOQ, accuracy, precision, and robustness as per ICH guidelines.
