摘要

The present invention provides a sustained release formulation comprising levetiracetam or a pharmaceutically acceptable salt thereof. The sustained-release preparation of the present invention uses a water-soluble polymer as a release control material so that the active ingredient levetiracetam is slowly released at a constant rate so that the blood concentration of levetiracetam can be kept constant even with a single dose, so that the patient's medication Convenience can be significantly improved.
