A reversed-phase high performance liquid chromatography (RP-HPLC) method was developed and validated for the estimation of Levetiracetam in bulk and tablets dosage forms. The separation was achieved on C18 analytical column (250 mm 4.6 mm i.d., 5.0 m) using acetonitrile and distilled water in the ratio 80:20 v/v as mobile phase and at a flow rate of 1.0 mL/min. Detection was carried out using a UV detector at 210nm. The total chromatographic analysis time per sample was about 5.0min with Levetiracetam eluting at retention time of about 3.5min. The method is accurate (99.51% - 100.45%), and the standard curve was linear over the concentration range of 25-150g/mL with R2 close to one (0.999) and Y-intercept of 0.022. The limit of detection (LOD) and limit of Quantitation (LOQ) obtained for Levetiracetam were 0.01g/mL and 0.09g/mL, respectively. The high recovery and low relative standard deviation confirm the suitability of the proposed method for the determination of Levetiracetam in tablets dosage form.
