A simple, precise, rapid and accurate reverse phase HPLC method developed for the estimation of levetiracetam in tablet dosage form. A Sun Fire C18, 250 x 4.6 mm, 5 μm partical size, with mobile phase consisting of acetonitrile and 0.03 M potassium dihydrogen phosphate (pH adjusted to 3.0 with orthophosphoric acid) in the ratio of 15:85 v/v was used. The flow rate was 1 mL /min and the effluents were monitored at 210 nm. The retention time was 5.53 min. The detector response was linear in the concentration of 20‐240 μg/mL. The respective linear regression equation being Y= 22119.684 x 6829.3428. The limit of detection and limit of quantification was 0.16 and 0.5 μg/mL respectively. The percentage assay of levetiracetam was 99.87%. The method was validated by determining its accuracy, precision and system suitability. The results of the study showed that the proposed RP‐HPLC method is simple, rapid, precise and accurate, which is useful for the routine determination of levetiracetam in bulk drug and in its pharmaceutical dosage form.
