Patent number: 6004969Abstract: Buprenorphine is a potent analgesic agent, it has been shown to be as effective as morphine. The main clinical application of buprenorphine is to relief postoperative pains or for patients in the terminal phase of cancer. The chance of becoming addiction and abuse is low, therefore it is pretty safe for clinical use. The half life of buprenorphine is short, since its hepatic extraction (extraction ratio is 0.7 to 0.9) and metabolism are high. For these reasons, oral administration of buprenorphine becomes impractical due to the need of giving drug frequiently. The present invention is related to enhancers used in transdermal preparations of narcotic analgesic agents. This invention employs pure components of Chinese herbs in a fixed ratio as transdermal penetration enhancers. Compositions of these transdermal preparations usually include 0.1 to 50% of narcotic analgesic agent, 0.Type: GrantFiled: October 9, 1997Date of Patent: December 21, 1999Assignee: National Science CouncilInventor: Oliver Yoa-Pu Hu

Patent number: 5962012Abstract: Scopolamine is a folksy cholinergic antagonist, and is used by parasympathetic nerves in autonomic nervous neurons as an anti-motion sickness drug or an anti-emesis drug. Since the human body most effectively absorbs this drug through the postauricular skin, the drug is administered by postauricular transdermal resorption patch. The penetrability of drug is increase by adding a dermal penetrative enhancer, because the penetration ability of patch-administered drugs is usually decreased by the penetrative blockade at dermal horny layers. The present invention discloses a penetration enhancer to increase dermal absorption and penetration of the cholinergic antagonist. The present invention finds that polyethylene and amide enhance penetration, about 2.2-2.8 fold. In accordance with the present invention, a penetration enhancer is added to the formulations of transdermal patch to increase the human body's absorption of scopolamine.Type: GrantFiled: February 11, 1998Date of Patent: October 5, 1999Assignee: Caleb Pharmaceuticals, Inc.Inventors: Wan-Yan Lin, Shu-Juan Chen, Chao-Wei Liao, Chien-Hsin D.
