A simple Reverse Phase liquid chromatographic (HPLC) method for the determination of Levetiracetam in human plasma has been developed. Separation was achieved on a Prontosil C8 (150×4.6 mm, 5 μm) column with mobile phase composition of [pH 3.8 buffer:acetonitrile] (Solution A): HPLC grade water (Solution B) in the ratio 60:40 v/v with ultra violet detection at 210 nm. Lower limit of quantitation was 200 ng/ml. Maximum between-run precision was 5.91%. Mean extraction recovery was found to be 100.02 to 103.06%. Stability study showed that after three freeze-thaw cycles the loss of three quality control samples were less than 10%. Samples were stable at room temperature for 48h and at -20° for 2 months. Before injecting onto HPLC system, the processed samples were stable for at least 6 h. The method was used to perform bioequivalence study in human.

Lower limit of quantitation was 200 ng/ml. Maximum between-run precision was 5.91%. Mean extraction recovery was found to be 100.02 to 103.06%.
