fentanyl
Fentanyl: A potent narcotic analgesic, abuse of which leads to habituation or addiction. It is primarily a mu-opioid agonist. Fentanyl is also used as an adjunct to general anesthetics, and as an anesthetic for induction and maintenance. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1078). fentanyl : A monocarboxylic acid amide resulting from the formal condensation of the aryl amino group of N-phenyl-1-(2-phenylethyl)piperidin-4-amine with propanoic acid. | 1.96 | 1 | 0 | anilide;

methadone
Methadone: A synthetic opioid that is used as the hydrochloride. It is an opioid analgesic that is primarily a mu-opioid agonist. It has actions and uses similar to those of MORPHINE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1082-3). methadone : A racemate comprising equimolar amounts of dextromethadone and levomethadone. It is a opioid analgesic which is used as a painkiller and as a substitute for heroin in the treatment of heroin addiction.. 6-(dimethylamino)-4,4-diphenylheptan-3-one : A ketone that is heptan-3-one substituted by a dimethylamino group at position 6 and two phenyl groups at position 4. | 1.96 | 1 | 0 | benzenes;

pentazocine
Pentazocine: The first mixed agonist-antagonist analgesic to be marketed. It is an agonist at the kappa and sigma opioid receptors and has a weak antagonist action at the mu receptor. (From AMA Drug Evaluations Annual, 1991, p97) | 1.95 | 1 | 0 | benzazocine | |
nalorphine
Nalorphine: A narcotic antagonist with some agonist properties. It is an antagonist at mu opioid receptors and an agonist at kappa opioid receptors. Given alone it produces a broad spectrum of unpleasant effects and it is considered to be clinically obsolete. | 2.36 | 2 | 0 | morphinane alkaloid | |
naloxone
Naloxone: A specific opiate antagonist that has no agonist activity. It is a competitive antagonist at mu, delta, and kappa opioid receptors.. naloxone : A synthetic morphinane alkaloid that is morphinone in which the enone double bond has been reduced to a single bond, the hydrogen at position 14 has been replaced by a hydroxy group, and the methyl group attached to the nitrogen has been replaced by an allyl group. A specific opioid antagonist, it is used (commonly as its hydrochloride salt) to reverse the effects of opioids, both following their use of opioids during surgery and in cases of known or suspected opioid overdose. | 2.87 | 4 | 0 | morphinane alkaloid;
