FUTURE DIRECTIONS IN CONTROLLED DRUG DELIVERY. The most exciting opportunities in controlled drug delivery lie in the arena of responsive delivery systems, with which it will be possible to deliver drugs through implantable devices in response to a measured blood level or to deliver a drug precisely to a targeted site.Feb 10, 2013 Rate Controlled Drug Delivery System Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising.

INTRODUCTION: Controlled drug delivery systems can include the maintenance of drug levels within a desired range, the need for fewer administrations, optimal use of the drug in question, and increased patient compliance. higher cost of controlledrelease systems compared with As the system floats over gastric contents, the drug Transdermal Drug Delivery Systems is released slowly at desired rate resulting in increased Membrane permeationcontrolled system gastric retention with reduced fluctuations in plasma drug Transderm Scop (scopolamine; CibaGeigy) concentration [9. rate controlled drug delivery system ppt RATE CONTROLLED DRUG DELIVERY SYSTEM. The rate of drug release is modulated by controlling the osmotic pressure gradient. a) Osmotic pressure activated DDS Depends on osmotic pressure to activate the drug release. The drug is activated to release

Novel oral drug delivery systems are broadly classified into two categories as they may controlled release dosage forms as well as targeting dosage forms. Generally controlled drug delivery preparations release the drug in a contolled manner in the GIT for rate controlled drug delivery system ppt PowerPoint Presentation: 8. Hydrationactivated drug delivery system Depends on the hydration induced swelling process to activate the release of drug Drug reservoir is homogeneously dispersed in a swellable polymer matrix fabricated from a hydrophilic polymer Release of the drug is controlled by the rate of swelling of the polymer matrix.

Drug molecules with very low aqueous solubility often have lower bioavailability because of the limited amount of dissolved drug at the site of absorption.
