Abstract
Abstract Opioid-containing pharmaceutical compositions are provided which are useful in effecting transdermal delivery of a therapeutic dose of the opioid to the systemic circulation of a mammal. These pharmaceutical compositions consist essentially of the opioid, a penetration enhancer which is at least one of a saturated fatty alcohol or fatty acid of 8-15 carbon atoms or of an unsaturated fatty alcohol or fatty acid of 8-18 carbon atoms, and a suitable pharmaceutical carrier, preferably propylene glycol.

Claim 1
Independent Claim
83 words
A method of administering a therapeutic dose of an opioid to the systemic circulation of a mammal which comprises topically administering to the mammal an opioid-containing pharmaceutical composition, wherein the composition consists essentially of a therapeutically effective amount of an opioid or a pharmaceutically acceptable salt thereof; an effective penetration enhancing amount of at least one of a saturated fatty acid of 8-15 carbon atoms or of an unsaturated fatty acid of 8-18 carbon atoms; and propylene glycol as a suitable pharmaceutical carrier.
Claim 2
Independent Claim
83 words
A method of administering a therapeutic dose of an opioid to the systemic circulation of a mammal which comprises topically administering to the mammal an opioid-containing pharmaceutical composition, wherein the composition consists essentially of a therapeutically effective amount of an opioid or a pharmaceutically acceptable salt thereof; an effective penetration enhancing amount of at least one of a saturated fatty acid of 8-15 carbon atoms or of an unsaturated fatty acid of 8-18 carbon atoms; and propylene glycol as a suitable pharmaceutical carrier.
Claim 3
Dependent Claim
57 words
A method according to claim 1 wherein the opioid is a natural or synthetic opioid analgesic such as morphine, oxymorphone, fentanyl, meperidine, propoxyphene, or oxycodone; a natural or synthetic narcotic antagonist such as nalmefene, naloxone, or naltrexone; a natural or synthetic mixed opioid agonist/antagonist such as nalbuphine, butorphanol, buprenorphine or pentazocine; or a pharmaceutically acceptable salt thereof.
