Jul 17, 2012 · Osmotic drug-delivery systems suitable for oral administration typically consist of a compressed tablet core that is coated with a semipermeable membrane coating. 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.

Oct 02, 2013 · 1. Introduction 1. Osmotic drug delivery uses the osmotic pressure for controlled delivery of drugs by using osmogens. 2. Osmosis : It refers to the process of movement of solvent from lower concentration of solute towards higher concentration of solute across the semipermeable membrane. 3.

patented osmotic drug delivery systems . Osmotic drug delivery systems are unique in the sense that the delivery of drug(s) is not dependent / influenced by physiological variables within the GIT, these systems are adaptable to a number of drugs, with minor modifications and the delivery of drug(s) can be made.File Size: 131KB

osmotic delivery system that results in a constant zero order release rate of drug. COMPONENTS OF OSMOTIC DRUG DELIVERY SYSTEMS[5, 6] Osmotic pumps contain a drug semi permeable membrane. The semi permeable membrane usually contains a plasticizer and in some cases surfactant and also pore forming agents.

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.
