This document discusses different types of controlled release drug delivery systems. It describes level preprogrammed systems which release drugs at predetermined fees, such as polymer membrane and matrix diffusion systems. In addition, it covers suggestions controlled systems where by drug release is activated by biological triggers, such as bioerosion, bioresponsive, and self-regulating systems.
This document summarizes a seminar on gastroretentive drug delivery systems (GRDDS). GRDDS are made to keep drugs from the tummy for prolonged amounts of time to allow for sustained drug release.

Sustained release drug delivery systems purpose to extend the therapeutic outcomes of drugs eventually.
A paste is basically an ointment that has a higher percentage of insoluble solids added. A great deal of particulate make any difference stiffens the system. When compared to the ointment, paste has lower permeability, reduce maceration and reduce warmth. When placed on the skin, they kind a good protective barrier [15].
