  • Publication number: 20050123615
    Abstract: A process for forming multiparticulates of azithromycin and a controlled release dosage form comprising multiparticulates of azithromycin and a pharmaceutically acceptable excipient are disclosed. The dosage form decreases the incidence and/or severity of GI side effects relative to currently available immediate release azithromycin dosage forms that deliver an equivalent dose. The dosage forms operate by effecting azithromycin release at a rate sufficiently slow to ameliorate side effects, yet sufficiently fast to achieve good bioavailability.
