Diffusion-controlled units are categorised into membrane-managed and monolithic or matrix systems. In membrane-controlled systems, the drug is contained inside the core like a reservoir and is covered by a thin polymeric membrane. The membrane could possibly be both porous or non-porous. The release of medicine is by diffusion from the membrane and the speed of release is governed by membrane thickness, porosity and physicochemical characteristics of medication (partition coefficient, molecular dimension and diffusivity, protein binding and dosage).

The drug release is thru diffusion when the outside layer that may be exposed to the solution receives dissolved initial, allowing for medicines to diffuse out from the matrix. In monolithic units, in which a drug is dissolved, drugs here are loaded underneath the solubility limit.
These types of drugs give quick dose necessities for conventional therapeutic responses, accompanied by a gradual release of medication in an amount of money enough to maintain the therapeutic reaction for precise extended amounts of time, normally 8-twelve hrs.
