Development and Validation of UV Spectroscopic Method for Estimation of Baricitinib

摘要

A simple, sensitive and reproducible spectrophotometric method for the analysis of Baricitinib in pure form and in its dosage form has been developed. Baricitinib is a synthetic antineoplastic and immunomodulating drug. Baricitinib is a selective and reversible Janus kinase 1 (JAK1) and 2 (JAK2) inhibitor. Janus kinases belong to the tyrosine protein kinase family and play an important role in the proinflammatory pathway signalling that is frequently over-activated in autoimmune disorders such as rheumatoid arthritis. Developed method obeyed beer’s law in a concentration range of 10-60 μg/ml with a correlation coefficient (Rsup2/sup) of 0.993. Quantification was carried out at 250 nm. Percentage assay of Baricitinib was found to be close to 100 %. The results of analysis have been validated statistically and recovery studies confirmed the accuracy of the proposed method.
