Publication number: 20030118651Abstract: There are provided bio-compatible means for delivery of at least one pharmaceutically active agent to a patient in need of same, comprising a bio-compatible, bio-degradable anionic or cationic carrier and at least one pharmaceutically active agent wherein the agent is cationic when the carrier is anionic and is anionic when the carrier is cationic. The delivery means further comprises at least one bio-compatible enclosing means for the carrier. This enclosing means may be bio-degradable or non bio-degradable and have a predetermined permeation gradient for the passage therethrough of the at least one pharmaceutically active agent. In an alternate embodiment the enclosing means may be biodegradable without a predetermined permeation gradient for the passage therethrough of the at least one pharmaceutically active agent.
