Jul 17, 2012 · Osmotic pumps are one of the systems for controlled drug delivery. Osmotic drug delivery systems typically consist of a drug core containing osmogen that is coated with a semipermeable membrane. This coating has one or more delivery ports through which a solution or suspension of the drug is released over time.Author: Rajesh A. Keraliya, Chirag Patel, Pranav Patel, Vipul Keraliya, Tejal G.

The drug delivery rates are independent of pH, and the delivery rate profiles are similar to those from the Alzet®. Other examples of osmotic pumps are the elementary and push-pull OROS® delivery system. As previously discussed, the first osmotic pumps were developed in the 1950s.

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

The osmotic-controlled release oral delivery system, OROS, is an advanced drug delivery technology that uses osmotic pressure as the driving force to deliver pharmacotherapy, usually once-daily, in several therapeutic areas. Oral route is one of the most extensively used routes of

Osmotically Controlled Drug Delivery System (OCDDS) Osmotic devices are the most calculable controlled drug delivery system (CDDS) and can be employed as oral drug delivery systems. Osmotic pressure is used as the driving force for these systems to release the drug in a controlled pattern.

Osmotic drug delivery devices are composed of an osmotically active drug core, which is surrounded by a rate controlling semipermeable membrane. Osmotic drug delivery system differ from diffusion based systems in that the way of delivery of the active agents is driven by an osmotic gradient somewhat than the concentration of drug in the device.

Basic components of Osmotically Controlled Drug Delivery System (Osmotic Pumps) Drug: Both water soluble and water insoluble drugs can be used in the osmotic pump systems. The drug candidate used in the osmotically controlled drug delivery should possess short biological half-life (2-6h), high potency and should be required for a chronic treatment.

Feb 05, 2015 · 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. 5. ADVANTAGES OF OSMOTIC DRUG DELIVERY SYSTEM The delivery rate of zero-order (which is most desirable) is achievable with osmotic systems. Delivery …
