Floating Drug Delivery System: An Overview

چکیده
Gastric emptying is a complex process and makes in vivo performance of the drug delivery systems uncertain. In order to avoid this variability, efforts have been made to increase the retention time of the drug-delivery systems for more than 12 hours. The floating or hydrodynamically controlled drug delivery systems are useful in such application. From the formulation and technological point of view, the floating drug delivery system is comparatively easy and logical approach. The present review addresses briefly about the floating drug delivery systems. It also summarizes methods of evaluation of various floating dosage forms and applications of these systems.

Ion-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...
