Description

Picenadol is a synthetic opioid analgesic that is structurally related to pentazocine. It acts as an agonist at the mu-opioid receptor and an antagonist at the kappa-opioid receptor. Picenadol has been studied for its potential to provide analgesia with fewer side effects than other opioids. It has shown efficacy in treating moderate to severe pain, but its use has been limited by concerns about its potential for abuse. Research on picenadol has focused on understanding its pharmacokinetic and pharmacodynamic properties, as well as its clinical efficacy and safety. Further studies are needed to fully evaluate its potential as a safe and effective analgesic.'

meperidine
Meperidine: A narcotic analgesic that can be used for the relief of most types of moderate to severe pain, including postoperative pain and the pain of labor. Prolonged use may lead to dependence of the morphine type; withdrawal symptoms appear more rapidly than with morphine and are of shorter duration.. pethidine : A piperidinecarboxylate ester that is piperidine which is substituted by a methyl group at position 1 and by phenyl and ethoxycarbonyl groups at position 4. It is an analgesic which is used for the treatment of moderate to severe pain, including postoperative pain and labour pain.		8.3511ethyl ester;

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.		1.9610benzenes;

buprenorphine
Buprenorphine: A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.. buprenorphine : A morphinane alkaloid that is 7,8-dihydromorphine 6-O-methyl ether in which positions 6 and 14 are joined by a -CH2CH2- bridge, one of the hydrogens of the N-methyl group is substituted by cyclopropyl, and a hydrogen at position 7 is substituted by a 2-hydroxy-3,3-dimethylbutan-2-yl group. It is highly effective for the treatment of opioid use disorder and is also increasingly being used in the treatment of chronic pain.		1.9610morphinane alkaloiddelta-opioid receptor antagonist;
