Reservoir gadgets, because the title indicates, are characterised by a Main of drug, the reservoir surrounded by a polymeric membrane. The nature with the membrane establishes the speed of release of drug within the system.
This document discusses differing kinds of controlled release drug delivery systems. It describes level preprogrammed systems which release drugs at predetermined costs, together with polymer membrane and matrix diffusion systems. Additionally, it covers feedback regulated systems where drug release is activated by biological triggers, which include bioerosion, bioresponsive, and self-regulating systems.
