Background Imatinib is a protein-tyrosine kinase inhibitor which is currently only commercially available as a tablet dosage form in the strength of 100mg and 400mg. The elaboration of new oral liquid formulations is suitable in pediatrics and for patients who have difficulties to swallow, notably in the absence of commercial forms. This enables the adaptation of dosage and secure the administration. Objectives The formulation of an oral pediatric solution of imatinib at a concentration of 30 mg/mL and the evaluation of its stability for the treatment of pediatric patients with Philadelphia chromosome positive chronic myeloid leukemia. Methods The physicochemical stability parameters: appearance, pH, osmolality, and drug content of formulation were evaluated for 30 days when stored at 2–8°C. Concentration of solution was measured with a validated method using high performance liquid chromatography (HPLC) coupled with an absorbance UV detector. Equally, microbiological stability was performed. Results The remaining imatinib concentration was at least 95% of the initial concentration after 30 days stored in fridge temperature. No changes were observed regarding the physical properties of the formulation during the study period. Conclusions The stability study showed that the imatinib oral solution at a concentration of 30 mg/mL provides an alternative option at the commercial tablet dosage forms for pediatric patients and patients who have difficulties to swallow.

Background: Axitinib (AXT) is a member of the new generation of the kinase inhibitor indicated for the treatment of advanced renal cell carcinoma. Its therapeutic benefits depend on assuring the good-quality of its dosage forms in terms of content and stability of the pharmaceutically active ingredient. Objective: This study was devoted to the development of a simple, sensitive and accurate stabilityindicating high-performance liquid chromatographic method with ultraviolet detection (HPLC-UV) for the determination of AXT in its bulk and dosage forms. Methods: Waters HPLC system was used. The chromatographic separation of AXT, internal standard (olaparib), and degradation products were performed on the Nucleosil CN column (250 × 4.6 mm, 5 μm). The mobile phase consisted of water:acetonitrile:methanol (40:40:20, v/v/v) with a flow rate of 1 ml/min, and the UV detector was set at 225 nm. AXT was subjected to different accelerated stress conditions and the degradation products, when any, were completely resolved from the intact AXT. Results: The method was linear (r = 0.9998) in the concentration range of 5-50 μg/ml. The limits of detection and quantitation were 0.85 and 2.57 μg/ml, respectively. The accuracy of the method, measured as recovery, was in the range of 98.0-103.6% with relative standard deviations in the range of 0.06-3.43%. The results of stability testing revealed that AXT was mostly stable in neutral and oxidative conditions; however, it was unstable in alkaline and acidic conditions. The kinetics of degradation were studied, and the kinetic rate constants were determined. The proposed method was successfully applied for the determination of AXT in bulk drug and dosage forms. Conclusions: A stability-indicating HPLC-UV method was developed and validated for assessing AXT stability in its bulk and dosage forms. The method met the regulatory requirements of the International Conference on Harmonization (ICH) and the Food and Drug Administration (FDA). The results demonstrated that the method would have great value when applied in quality control and stability studies for AXT.

Imatinib is a type of protein tyrosine kinase inhibitor which inhibits the constitutive abnormal tyrosine kinase created by the Philadelphia chromosome i.e. the BCR-ABL tyrosine kinase, abnormality in CML patient. The aim of the study is to assess the response of imatinib in CML patients and to observe resistance to imatinib. Study was performed at Ahmedabad, Gujarat, India. Dose of 400, 600, 800 mg of Imatinib was found to be prescribed to all patients during the study. Comparison of laboratory parameters and PCR data were done after measurement by RT-PCR method. Total 256 patients with CML were enrolled in the study. 196 patients had completed study as per protocol. 38 patients were newly diagnosed whereas 158 patients were already diagnosed with CML. 89.29% (n = 175) of patients achieved complete haematological response, Complete MolR were achieved in n = 41 at 6th months, n = 1 at 12th month and 18th month and no patient was found with none CyR out of 196 patients; no patient were found with minimal CyR at 6th month, 2 patient were at 12th month and 3 patients were at 18th month. Mean PCR value (BCR-ABL/ABL ratio) in patient was found 0.245±1.16 at Day 0, 0.824±1.51 at 6th month, 4.086±9.58 at 12th month and 6.713±11.32 at 18th month visit. In conclusion, it was observed that resistance to imatinib might be developed within an average time of 12 months in the patients due to which survival rate was drastically reduced.

Abstract This paper describes validated HPLC and HPTLC methods for the simultaneous determination of rosuvastatin (ROS) and ezetimibe (EZE) in a combined tablet dosage form. The isocratic RP-HPLC analysis was performed on a Chromolith C18 column (100 6 mm id) using 0.1 (v/v) orthophosphoric acid solution (pH 3.5)acetonitrile (63 + 37, v/v) mobile phase at a flow rate of 1 mL/min at ambient temperature. Quantification was carried out using a photodiode array UV detector at 245 nm over the concentration range of 0.510 g/mL for ROS and EZE. The HPTLC separation was carried out on an aluminum-backed sheet of silica gel 60F254 layers using n-butyl acetatechloroformglacial acetic acid (1 + 8 + 1, v/v/v) mobile phase. Quantification was achieved with UV densitometry at 245 nm over a concentration range of 0.10.9 g/spot for ROS and EZE. The analytical methods were validated according to International Conference on Harmonization guidelines. Low RSD values indicated good precision. Both methods were successfully applied for the analysis of the drugs in laboratory-prepared mixtures and commercial tablets. No chromatographic interference from the tablet excipients was found. These methods are simple, precise, and sensitive, and are applicable for simultaneous determination of ROS and EZE in pure powder and tablets.
