Abstract
In accordance with the present invention, the controlled release formulation contains coated pellets of indomethacin of only one type. The pellet releases indomethacin in both immediate and sustained release form. The immediate release indomethacin is rapidly absorbed from the stomach to provide a bolus dose of active agent. The sustained release indomethacin is gradually released over time to maintain the blood levels at effective concentrations for long periods of time.
