ABSTRACT:
A sustained-release pranoprofen preparation is disclosed. The preparation comprises an effective amount of pranoprofen and one or more sustained-release components selected from the group consisting of oily components, water-soluble components, water-insoluble components, and intestinally soluble components. It controls release of pranoprofen and lowers the maximum pranoprofen concentration in blood, maintaining its concentration in blood at a certain level for a long period of time. It reduces risks of side effects and can effectively treat diseases with dosing once or twice a day.
