For the reservoir systems shown in Figures 3a and 3b the drug delivery rate can remain fairly constant. 3 Improved effic iency in treatment Cures or controls condition more promptly. Drug from pharmaceutical dosage form the matrix system is the most frequently applied.
Ideal for systemic drug delivery administration. In fact a matrix is defined as a well-mixed composite of one or more. Hydrophillic matrix systems are among the most commonly used means for oral controlled drug delivery as they can reproduce a desirable drug profile and are cost effective Prajapati and Patel 2010 The Dow Chemical Company 2000.
11 Matrix systems are widely used for the purpose of sustained release. This review focus on in-depth knowledge of matri x drug delivery system. Matrix tablet Sustained release matrix.
The release rate is controlled by the dissolution rate of drug in the carrier matrix. Within this context at least four different types of devices can be envisioned.

Drug delivery from a typical matrix drug delivery system.
MATRIX DRUG DELIVERY SYSTEM. It is the release system which prolongs and controls the release of the drug that is dissolved or dispersed. Polymer matrix or matrices. 2 Employ less total drug Minimize or eliminate local side effects Minimize or eliminate systemic side effects. Matrix delivery systems with Dissolved Drugs Drug molecules are dissolved homogeneously in biocompatible polymer Drug molecules are released by diffusing through polymer to the surface of the device and further released into the external environment dcdt D ip d2cdx2. Adhesive patch that is placed on the skin to deliver a specific dose of medication through the skin and into bloodstreamthe. Within this context at least four different types of devices can be envisioned. The search for a magic bullet has been the major focus of drug delivery and drug discovery research for many years Ehrlich and Bolduan 1906If active agents or delivery systems can be devised that selectively treat a disease while having no affect on healthy cells tissues and organs that particular disease will no longer plague humankind.

For the reservoir systems shown in Figures 3a and 3b the drug delivery rate can remain fairly constant. In case the carrier matrix is also biodegradable the release rate is also controlled by the degradation rate of the matrix. Long circulating macromolecular carriers such as liposomes can exploit the enhanced permeability and retention effect for preferential extravasation from tumor vessels. For the reservoir systems shown in Figures 3a and 3b the drug delivery rate can remain fairly constant. Improves control of. Its release system for delay and control of the release of the drug that is dissolved or dispersed in a resistant supports to disintegration. Thus an attempt has been made to formulate the extended-release matrix tablets of Metformin Hydrochloride and tested for controlled delivery of drug using hydrophilic matrix polymer Hypromellose or HPMC K15M HPMC K100M HPMC K200M and Polyacrylate polymers Eudragit RL100 and Eudragit RS100 alone or in combination with hydrophobic ethyl cellulose to produce additive antidiabetic.
