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.

The particles may be very small and suspended in a liquid medium.
