Stability Indicating RP HPLC method was developed for estimation of Itraconazole in bulk drug and in capsule dosage form. An isocratic separation was achieved using Phenomenex symmetry C8 (250 ×4.6 mm) 5?m [Part number - 00G-4249-E0] column with a flow rate of 1.0 ml/min and detection wavelength at 254 nm. The mobile phase consisted of 20 mM potassium dihydrogen orthophosphate buffer (pH=5.5): Acetonitrile: Methanol (20:40:40 % v/v). The method was rectilinear from 10-60 ?g/ml and displayed adequate precision (RSD < 2.0%) & accuracy (99.31-101.16%). The proposed method is found to be specific with respect to degradation product formed after Acidic hydrolysis, Oxidation, Thermal and Photolytic degradation. The Itracoazole was found to be stable under alkaline stress condition. Acidic, thermal, photolytic stress conditions showed moderate degradation whereas the oxidative stress condition showed severe degradation. The proposed chromatographic method can be used for estimation of drug during stress testing & formal stability studies.

A simple, precise, accurate and sensitive isocratic stability indicating RP-HPLC method has been developed and validated for determination of Ketoconazole in bulk drug and pharmaceutical dosage form. Isocratic RP-HPLC separation was achieved on Agilent C8 (150 mm ?4.6 mm, 5 µm particle size) with the mobile phase 0.3 % Triaethylamine in 20 mM potassium dihydrogen phosphate buffer pH adjusted to 4.0: Acetonitrile (68:32 % v/v) at a flow rate 1.0 ml/min. The retention time of Ketoconazole was 8.97 ± 0.50 min. The method was validated for specificity, linearity, precision, accuracy and robustness. The linear regression analysis data of calibration curve showed good linearity in concentration range 10-60 ?g/ml. The Intraday and Interday precision were 0.59-1.11 % and 0.26-1.73 % RSD respectively. The accuracy was found to be 98.11-99.26 %. The drug was subjected to the stress conditions like hydrolysis, oxidation, photolysis and dry heat. The proposed method is found to be specific with respect to degradation product formed after Acidic hydrolysis, Oxidation, Thermal and Photolytic degradation. The Ketoconazole was found to be stable under neutral hydrolytic, thermal and photolytic stress conditions. Acidic, thermal, photolytic stress conditions showed degradation. The proposed chromatographic method can be used for estimation of drug during stress testing & formal stability studies.

The aim of this paper was to develop and validate the stability indicating RP-HPLC method for the determination of Imatinib mesylate in bulk and pharmaceutical dosage forms. A simple, accurate, precise, sensitive and stability indicating RP-HPLC method has been developed for the determination of Imatinib mesylate in bulk drug and pharmaceutical dosage form, in which separations are done using develosil C18, 5μm, 150 × 4.6mm i.d. column at a flow rate of 1.0mL/min with an injection volume of 20μL. The beer’s law was obeyed over the concentration range of 5 - 35μg/mL. The correlation coefficient was found to be 0.996 and it showed good linearity, reproducibility, precision in this concentration range. The % recovery values were found to be within the limits, which showed that the method was accurate. The LOD and LOQ were calculated using statistical methods. The % RSD values were less than 2. The developed method was successfully applied for determination of Imatinib mesylate in pharmaceutical dosage form. The results obtained are in good agreement with those obtained by using the standard method.

A simple validated RP HPLC method for the estimation of rizatriptan benzoate in pharmaceutical dosage form and bulk was developed for routine analysis. This method was developed by selecting Agilent TC C18 (250 x 4.6 mm, 5 μ) column as stationary phase and acrylonibrile:water (45:55), pH adjusted to 3, as mobile phase. Flow rate of mobile phase was maintained at 4: 1 mL/min at ambient temperature throughout the experiment. Quantification was achieved with ultraviolet (DAD) detection at 220 nm. The retention time obtained for rizatriptan was 2.8 min. The detector response was linear in the concentration range of 2-25μg/mL. This method was validated and shown to be specific, sensitive, precise, linear, accurate, rugged and robust. Hence, this method can be applied for routine quality control of rizatriptan benzoate in dosage forms as well as in bulk drug.

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.
