SYSTEM FOR DELIVERING AN ACTIVE SUBSTANCE FOR SUSTAINED RELEASE |
摘要 |
A system for delivering an active substance has sustained release of the active substance in the intestinal tract. This delivery system is especially useful for an active substance such as a .beta.-lactam antibiotic which preferably has minimal exposure to the acidic environment of the stomach. Particles comprise an active ingredient disposed in a core which has at least one coating of a prolamine and one coating of an enteric compound thereon. The particles may be very small and suspended in a liquid medium.
