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 …

Osmotic drug delivery uses the osmotic pressure for controlled delivery of drugs by using osmogens (for upto 10 – 16 hrs). Osmotic pressure is a most important colligative property according to pharma point of view. Colligative property is the concentration of solution independent of solute property.File Size: 572KB

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.

Mar 13, 2014 · Introduction Osmotic drug delivery define as the modified-prolong release system, that uses the osmotic pressure for controlled delivery or release of drugs by using osmogens. Osmogens or Osmotic agents are the water soluble substances, that create osmotic pressure in to the system.

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.

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.

Oct 02, 2013 · 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.

Osmotic drug delivery systems for oral and parenterals use offer distinct and practical advantages over other means of delivery. The following advantages have contributed to the popularity of osmotic drug delivery systems [14,15]. 1. The delivery rate of zero-order is achievable with osmotic systems.
