چکیده

the purpose of this review article is to characterize all of the parameters regarding the types, polymers used, and release kinetics of matrix tablets. matrix system was the earliest oral extended release platform for medicinal use. matrix tablets are most commonly used methods to modulate the release profile of drugs. they are much desirable and preferred for such therapy because they offer better patient compliance, maintain uniform drug levels, reduce dose and side effects, and increase safety margin for high potency drugs. hydrophilic polymer matrix systems are widely used for designing oral controlled drug delivery dosage forms because of their flexibility to provide a desirable drug release profile, cost effectiveness, and broad regulatory acceptance. however, the use of hydrophilic matrix alone for extending drug release for highly water soluble drugs is restricted due to rapid diffusion of the dissolved drug through the hydrophilic gel network. for such drugs it becomes essential to include hydrophobic polymers in the matrix system. this leads to the conclusion that matrix tablets seem to be most promising when developing an oral controlled release formulation.

LITERATURE ON CONTROLLED RELEASE DRUG DELIVERY SYSTEMS (MICROCAPSULES AND MATRIX TABLETS) Controlled release drug delivery systems

Controlled release drug delivery systems 1 are those dosage formulations designed to release an active ingredient at rates, which differ significantly from their corresponding conventional dosage forms. The controlled release drug delivery systems are aimed at controlling the rate of drug delivery, sustaining the duration of therapeutic activity and/or targeting the delivery of the drug to a ti...

The role of oral controlled release matrix tablets in drug delivery systems.

Formulations that are able to control the release of drug have become an integral part of the pharmaceutical industry. In particular oral drug delivery has been the focus of pharmaceutical research for many years. This type of drug delivery has been at the centre of research due to its many benefits over conventional dosage. The focus of this review is on matrix tablets due to their widely use ...

Polysaccharide gum matrix tablets for oral controlled delivery of Cimetidine

Matrix-based tablets using 40 %w/w grewia gum were prepared by direct compression to contain cimetidine as novel drug. The formulations were compared with similar formulations using hydroxypropyl methylcelluose (Methocel), gum arabic, carboxy methylcellulose (Blanose), or ethyl cellulose (Ethocel) as polymer matrix. Also binary composite matrices containing grewia gum and the reference polymers...
