ABSTRACT

A new, simple, specific, accurate and precise RP-HPLC method was developed for determination of Baclofen. In the present study, stress testing of Baclofen was carried out according to ICH guidelines Q1A (R2). Baclofen was subjected to stress conditions of hydrolysis, oxidation, photolysis and neutral decomposition. Extensive degradation was found to occur in acidic, condition. Mild degradation was observed in basic and at thermal conditions. Successful separation of drug from degradation products formed under stress conditions was achieved on a Hypersil BDS C18 column (250 mm × 4.6 mm, 5.0 μ particle size) using acetonitrile: acetate buffer (pH 3.7 ± 0.05) (50:50 v/v), at a flow rate of 1.0 mL/min and column was maintained at 40˚C. Quantification and linearity was achieved at 272 nm over the concentration range of 5 - 100 μg/mL for Baclofen. The method was validated for specificity, linearity, accuracy, precision, LOD, LOQ and robustness.

Keywords: Stability-indicating, HPLC, Baclofen, Validation, Stress Testing.
