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.

Objective: This study describes the stability-indicating reverse-phase high-performance liquid chromatography (RP-HPLC) method for simultaneous estimation of betahistine dihydrochloride and domperidone in pharmaceutical dosage forms.Methods: The proposed RP-HPLC method was developed using Shimadzu Prominence-i LC-2030 HPLC system equipped with UV detector and chromatographic operation was carried on Shim-pack C18 (250 mm×4.6 mm, 5 μ) column at a flow rate of 1 ml/min and the run time was 10 min. The mobile phase consisted of methanol and water in the ratio of 80:20% v/v and eluents were scanned using a UV detector at 244 nm.Results: The retention time of betahistine dihydrochloride and domperidone was found to be 2.3 and 3.6 min, respectively. A linearity response was observed in the concentration range of 9.6 μg/ml–22.4 μg/ml for betahistine dihydrochloride and 6–14 μg/ml for domperidone, respectively. Limit of detection and limit of quantification for betahistine dihydrochloride were 0.52 μg/ml and 1.58 μg/ml and for domperidone are 0.64 μg/ml and 1.94 μg/ml, respectively.Conclusion: The stability-indicating method was developed by subjecting drugs to stress conditions such as acid and base hydrolysis, oxidation, photo and thermal degradation, and degraded products formed were resolved successfully from samples.

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.
