Transdermal therapeutic systems for the administration of nalozone, naltrexone and nalbuphine.

摘要

A method for transdermal delivery of naloxone, naltrexone and nalbuphine base through intact skin is described. Preferred embodiments of transdermal therapeutic systems for delivering these drugs and polyethylene glycol monolaurate employ an ethylene vinylacetate matrix containing drug base at a concentration above saturation and polyethylene glycol monolaurate below unit activity. Polyethylene glycol monolaurate is disclosed as a permeation enhancer for the base form of these drugs and is preferably delivered simultaneously with the drug.
