A rapid, sensitive, and accurate stability indicating HPLC method was developed for the simultaneous determination of triamcinolone acetonide and benzyl alcohol in pure form, degradation products and pharmaceutical preparation. The separation was carried out on RP BDS Hypersil® C18 column (150 x 4.60 mm, 5μm) using an isocratic mobile phase composed of acetonitrile: 0.05 M phosphate buffer PH 3.50 (55 : 45). Both benzyl alcohol and triamcinolone acetonide quickly eluted at 1.67 min and 3.42 min, respectively, with a flow rate of 1.50 mL /min and UV detection at 254 nm. The linearity was in the range of 1 – 50 µg/mL for triamcinolone acetonide and 2 - 10 µg/mL for benzyl alcohol. The method has been validated for linearity, accuracy, precision, specificity, limit of detection, limit of quantification, robustness, and ruggedness as per the ICH guidelines. Finally, the method was compared statistically with reference methods indicating that there is no significant difference between them in respect of precision and accuracy.

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.

The present study aims to develop a simple, accurate and specific stability-indicating RP-HPLC technique for the analysis of metoclopramide in the presence of its stress degradation products and characterization of degradation compounds by LC-MS/MS analysis. As per ICH Q1A-R2 guidelines, the drug was exposed to acid hydrolytic stress condition. Three degradation products were formed for MCP in acid hydrolysis. The liquid chromatography was processed on a Luna C18-(2) 100A,250×4.6mm 5micron column using an isocratic mobile phase consisting of 0.1% formic acid in water-acetonitrile (20:80, v/v) by adjusting the mobile phase at 1 ml/min flow rate with wavelength detection at 273 nm. The developed procedure was applied to LC-MS/MS (liquid chromatography-tandem mass spectrometry) for the characterization of all the degradant components. Total new three degradation compounds were recognized and identified by LC-MS/MS. The developed RP-HPLC technique was validated as per the ICH Q2-R1 guidelines. Limit of detection and limit of quantification values of MCP were evaluated from the linearity graph and were found to be 5.23 µg/ml and 17.44 µg/ml. Accuracy study was established at 80.0, 100.0 and 120.0 µg/ml concentration levels and the findings were found in the range of 98.4% - 101.8%. The linearity of the technique was assessed over the drug concentration range of 50.0 µg/ml to 250.0 µg/ml and the regression equation, slope and correlation coefficient values were found to be y = 10618x + 1623.2, 10618 and 0.9996 respectively. The developed technique was uninterruptedly applied for the quantification of metoclopramide inactive pharmaceuticals.

A combined dose tablet formulation containing Amlodipine besylate and Lisinopril is used for the treatment of essential hypertension. The present study reports development and validation of stability indicating high performance thin layer chromatographic method for simultaneous estimation of these drugs in combined dose tablet formulation. The two drugs were satisfactorily resolved on aluminum plates precoated with silica gel 60F254 using n-butanol : methanol: ammonia (4:4:1 v/v/v) as mobile phase. The Rf value for lisinopril and amlodipine besylate were 0.27±0.02 and 0.62±0.02, respectively. Densitometric evaluation of the separated bands was performed at 215nm. The calibration curves for lisinopril and amlodipine besylate were found to be linear in the concentration range of 1000-6000ng/band. The method was validated as per ICH guidelines for accuracy, precision, robustness, specificity, limit of detection and limit of quantitation. Statistical analysis proves that the method is suitable for simultaneous analysis of Lisinopril and Amlodipine besylate in pharmaceutical formulation without any interference from the excipients/degradant. The developed method offers several advantages such as sensitive, rapid, cost effective and less time consuming as compared to the reported methods. As the method could effectively separate the drugs from its degradation products, it can be employed as a stability indicating method.

A precise, accurate, economical and simple stability indicating RP-HPLC method was developed for the estimation of Amlodipine (AML) and Olmesartan (OLM) in bulk and pharmaceutical dosage form. Method was performed on a octadecyl silane column with dimensions 4.6 x 250 mm having particle size 5 micron. The mobile phase used in the method is TEA Buffer (pH 3.0) and acetonitrile in proportion of 25:75 respectively. The flow rate was maintained at 1.0 ml/ min and effluent was monitored at 258 nm. The drug was subjected to acid and alkali hydrolysis, oxidation, photolysis and heat as stress conditions. The method was validated for specificity, linearity, precision, accuracy, robustness and system suitability. The retention times were observed at 2.39 min and 3.33 min for AML and OLM respectively. The standard curve was found linear over a range of 05–35 μg/ml for AML and OLM. Similarly an average correlation coefficient was also obtained at 0.999 for AML and OLM. The limit of quantitation (LOQ) of this method was 2μg/ml for Amlodipine and Olmesartan. The absolute recovery was 100% for Amlodipine and 100.3 for Olmesartan. Degradation products produced as a result of stress studies did not interfere with the detection of AML and OLM and the assay can thus be considered stability-indicating.
