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 o...

The aim of this study was to formulate and evaluate microencapsulated controlled release preparations of a highly water/soluble drug, salbutamol sulphate by (water in oil) in oil emulsion technique using ethyl cellulose as the retardant material. Various processing and formulation parameters such as drug/polymer ratio, stirring speed, volume of processing medium were optimized to maximize the e...

hydrogel based metronidazole bioadhesive tablet (hmbt) was prepared as a novel vaginal delivery system to achieve controlled release of drug from the tablet for vaginal candidiasis. the highly swollen hydrogel were prepared by dissolving chitosan in acetic acid solution containing drug, followed by neutralisation with sodium hydroxide and characterized by sem, dsc and ft-ir and evaluated for % ...

the objective of the present study was to design an oral controlled drug delivery system for sparingly soluble diclofenac sodium (dcl) using guar gum as triple-layer matrix tablets. matrix tablet granules containing 30% (d1), 40% (d2) or 50% (d3) of guar gum were prepared by the conventional wet granulation technique. matrix tablets of diclofenac sodium were prepared by compressing three layers...
