Feb 05, 2015 · Osmotic drug delivery system. 1. 4. INTRODUCTION Osmotic drug delivery uses the osmotic pressure of drug or other solutes (osmogens or osmagents) for controlled delivery of drugs. Osmotic drug delivery has come a long way since Australian physiologists Rose and Nelson developed an implantable pump in 1955.

system. Osmotic drug delivery systems (ODDS) differ from diffusion-based systems in that; the delivery of the active agent(s) is driven by an osmotic gradient rather than the concentration of drug in the device [Ende et al. 2005]. Osmotic devices are most promising strategy based systems for controlled drug delivery.File Size: 131KB

Jul 17, 2012 · Controlled drug delivery systems offer spatial control over the drug release. Osmotic pumps are most promising systems for controlled drug delivery. These systems are used for both oral administration and implantation. Osmotic pumps consist of an inner core containing drug and osmogens, coated with a semipermeable membrane.Author: Rajesh A.

The pump consists of an osmotic core containing the drug, surrounded by a semipermeable membrane with a delivery orifice. When this pump is exposed to water, the core imbibes water osmotically at a controlled rate, determined by the membrane permeability to water and by the osmotic pressure of the core formulation.File Size: 649KB

PRINCIPLE OF OSMOTIC DRUG DELIVERY SYSTEM OSMOSIS Movement of solvent from lower to high concentration through semi permeable membrane OSMOTIC PRESSURE Hydrostatic pressure applied to more concentrated solution to prevent transport of water across the membrane.
