An isocratic stability-indicating reverse phase high performance liquid chromatographic diode array detection method has been developed and validated for the quantitative determination of pitavastatin calcium in the presence of its degradation products. The chromatographic separation was achieved on Phenomenex Luna C18 column (250 X 4.0 mm id, 5μm) in the isocratic mode using acetonitrilemethanol- water (35:25:40, v/v/v, pH 3 adjusted with orthophosphoric acid) as mobile phase. The drug is subjected to different accelerated stress conditions and peaks of the degradation products were well resolved from the pure drug, which indicates the specificity and stability-indicating properties of the method. The method was linear (r= 0.9998) over the concentration range of 5-30 μg/mL. The proposed method was used to investigate the degradation kinetics of PTV in acidic condition at different temperatures. Degradation of pitavastatin followed first-order kinetics, and rate constant (k), half life (t1/2), time left for 90% potency (t90) and energy of activation were calculated.

A simple, economic, accurate, sensitive, specific and precise stability indicating reverse phase high performance liquid chromatographic [RP-HPLC] method for the determination of Regorafenib in pure and tablet dosage from was developed and validated. The chromatographic separation was carried out using Phenomenex Luna-C18 column (4.5x250 mm; 5 µm particle size) as a stationary phase and methanol: acetonitrile: water (55:25:20 v/v/v) as a mobile phase. The flow rate of 1 mL/min was used with PDA detection at 275 nm. The retention time of Regorafenib was 2.480 min. RP-HPLC method was developed with linearity range of 40-240 µg/mL of Regorafenib. The correlation coefficient [r2] was found to be 0.9999. The assay results obtained was in good agreement with the corresponding labeled amount by developed method within range of 98.83 ± 0.6937. Accuracy of the method was confirmed by recovery studies and the recoveries were found to be between 99.61 % and 100.22 %, the corresponding %RSD was found to be 0.2029. Precision, LOD, LOQ, specificity, robustness and ruggedness were performed as per ICH Q2(R1) guidelines and were within the acceptance criteria. This method can be conveniently used to detect the possible degradation product in the dosage form of Regorafenib during stability studies (acidic, alkaline, oxidative, thermal and photolytic). The method proved to be effective on the analysis of stressed marketed tablet formulation.

A stability-indicating high-performance liquid chromatographic (HPLC) method was developed with short run time and validated for the assay of process related impurities of pantoprazole in bulk form. Resolution of drug, its potential impurities and degradation products were achieved on a Hypersil ODS column utilizing a gradient with 0.01 M phosphate buffer of pH 7 and acetonitrile as eluent, at the detection wavelength of 290 nm. Flow rate was set at 1 mL min-1. The procedure was found to be specific, linear (r=0.999), recovery (97.9-103%), LOD (0.043-0.047 µgmL-1), LOQ (0.13-0.14 µgmL-1) and robust. Acceptable robustness indicates that the assay method remains unaffected by small but deliberate variations. Pantoprazole was found to degrade in acidic, oxidative and under photolytic stress conditions. The drug was stable to alkaline and dry heat conditions. This method has been successively applied to pharmaceutical formulation and no interference from the excipients was found.

A sensitive, selective, precise and stability-indicating, new high-performance liquid chromatographic method for the analysis of carvedilol both as a bulk drug and in formulations was developed and validated. As the method could effectively separate the drug from its degradation products, it can be employed as a stability-indicating one. The method was validated for linearity, selectivity, precision, robustness, LOD, LOQ and accuracy. The chromatographic separation was achieved on a Chromolit RP8e, 100x4.6 mm, analytical column. The mobile phase consisted of a mixture of acetonitrile and water (45:55, V/V) (pH 2.5), pH adjusted with formic acid. The absorbance was monitored with a UV detector at 280 nm and the temperature of the analyses was 40?C. The flow rate was 0.5 mL/min. The linearity (r? 0.999), reproducibility (0.68-1.27 %) and recovery (99.71-101.58) were found to be satisfactory. This method enables the simultaneous determination of carvedilol and its degradation products, as well as stability. .

A simple, accurate, precise high-performance liquid chromatographic (HPLC) method has been developed and validated for the simultaneous determination of abacavir sulphate (ABA) and lamivudine (LAM) in combined dosage form. Separation was performed on a C18 column [Agilent ODS UG 5 column, 250 mm x 4.5 mm], with methanol: water (50:50 V/V) isocratic elution using a flow rate of 1mL/min. Good sensitivity was observed with UV detection at 277 nm. After method development, the interference of other active compounds and excipients, repeatability and linearity, were investigated. Retention times of LAM and ABA were found to be 3.3 and 6.3 min, respectively. The method was validated over the range from 2.5-12.5 μg/mL for LAM and 5-25 μg/mL for ABA with correlation coefficients of 0.9997 and 0.9996, respectively. This method was shown to be accurate, robust, selective, linear, and repeatable and can be successfully employed in routine quality control for the simultaneous analysis of ABA and LAM in tablets.

Abstract The purpose of this work was to develop a sensitive, selective, and validated stability-indicating high-performance liquid chromatographic (LC) assay of atorvastatin (ATV) in bulk drug and tablet form. ATV was subjected to different stress conditions, including UV light, oxidation, acid-base hydrolysis, and temperature. ATV and its degradation products were analyzed on an Agilent Zorbax XDB C18 column using isocratic elution with acetonitrile0.02 M sodium acetate, pH 4.2 (45 + 55, v/v) for 25 min. The samples were monitored with fluorescence (FL) detection at 282 nm (excitation)/400 nm (emission). The response ratio of FL to UV detection (at 247 nm) for ATV was 1.66. The method showed good resolution of ATV from its decomposition products. The photodegradation products were separated by silica gel thin-layer chromatography using double development with ethyl acetaten-hexaneglacial acetic acidmethanol (40 + 55 + 0.5 + 4.5, v/v/v/v) followed by (39 + 55 + 0.5 + 5.5, v/v/v/v), and confirmed by LC-FL analysis. The FL response was linear over the investigated range for ATV. The linear range was 101200 ng/injection, and the limit of quantitation was 2.0 ng/injection.

Objective: The objective of the study was to develope a stability indicating high-performance liquid chromatographic (HPLC) method for simultaneous assay of pentazocine and naloxone in bulk and tablets. Methods: Pentazocine and naloxone were analyzed on Dionex C18 column using 0.1M K2HPO4 buffer (pH 4.0) and methanol (60:40, v/v) as the mobile phase. The concentration of pentazocine and naloxone was quantified by photodiode array detector set at 248 nm. The method was validated in compliance with ICH rules. Pentazocine and naloxone tablet formulation was subjected to forced degradation such as acid, neutral and alkali hydrolysis, oxidation, photo, and thermal degradation. Results: The method was linear, with R2=0.9999 in the concentration range 100–300 μg/ml for pentazocine and R2=0.9995 in the concentration range 1–3 μg/ml for naloxone. The level of detection and quantification was 0.097 μg/ml and 0.322 μg/ml for pentazocine and 0.0073 μg/ml and 0.0243 μg/ml for naloxone, respectively. The degraded products are resolved well from pentazocine and naloxone with significantly different retention time values. From validation results, it was proved that the method is selective, precise, robust, and accurate for the estimation of pentazocine and naloxone simultaneously. Conclusion: The developed stability-indicating HPLC method can be applied for quantitative determination of pentazocine and naloxone in tablets.
