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.

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.

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.

INTRODUCTION: Oral drug delivery is the most preferred and convenient choice as the oral route provides maximum active surface area among all drug delivery system for administration of various drugs 1. In conventional oral drug delivery systems, there is little or no control over release of the drug and effective concentration at the target site can be achieved by irregular administration of excessive …
