Floating Drug Delivery System
The aim of writing this review on gastro retentive and floating drug delivery system was to compile the new literature with the principle mechanism of floatation to acquired gastric retention. Various attempts have been made to develop gastroretentive delivery systems such as high density system, swelling, floating system. In floating multiple unit and single unit system are design and their cl...
متن کاملIon-exchange, an Approach to Prepare an Oral Floating Drug Delivery System for Diclofenac
Using ion-exchange resins, a multiple-unit type of oral floating dosage system has been prepared to prolong gastric emptying time of dosage form. The system is composed of beads of drug-resin complex, which are loaded with bicarbonate ions and coated with a hydrophobic polymer. The system is so designed that when the beads reach the stomach, chloride ions are exchanged with bicarbonate and drug...
متن کاملFloating Drug Delivery Systems: a Novel Approach
During the past few decades, numerous oral drug delivery systems have been developed to act as drug reservoirs from which the active substance can be released over a specific period of time at a predetermined and controlled rate. It is evident from the recent scientific and patent literatures that an increased interest in novel oral controlled release dosage forms that designed to be retained i...
متن کاملFloating drug delivery systems: A better approach
The purpose of writing this review on floating drug delivery systems (FDDS) was to compile the recent literature with special focus on the principal mechanism of floatation to achieve gastric retention. It is known that differences in gastric physiology (such as, gastric pH, motility) exhibit both intraas well as inter-subject variability demonstrating significant impact on gastric retention ti...
