Revivon · Diprenorphine Hydrochloride
Diprenorphine (brand name Revivon; former developmental code name M5050), also known as diprenorfin, is a non-selective, high-affinity, weak partial agonist of the μ- (MOR), κ- (KOR), and δ-opioid receptor (DOR) (with equal affinity) that is employed in veterinary medicine as an opioid antagonist. It is used to reverse the effects of super-potent opioid analgesics such as etorphine and carfentanil that are used for tranquilizing large animals. The drug is not approved for use in humans.
Cyprenorphine (M-285) is an opioid drug. It is related to more well-known opioids such as buprenorphine, which is used as an analgesic and for the treatment of opioid addiction, and diprenorphine, which is used as an antidote to reverse the effects of other opioids. Cyprenorphine has mixed agonist–antagonist effects at opioid receptors, like those of buprenorphine.
Azacyclonol (trade names Ataractan, Calmeran, Frenoton, Frenquel, Psychosan), also known as γ-pipradrol, is a drug which is an ataractive; an agent which diminishes hallucinations in psychotic individuals. It has also been called a tranquilizer and antipsychotic, though these definitions are not accurate as it does not actually possess such properties. Despite being a positional isomer of pipradrol, it is not a psychostimulant, and instead has mild depressant effects.
TENOCYCLIDINE (21500-98-1, 1867-65-8)
Tenocyclidine (TCP) was discovered by a team at Parke Davis in the late 1950s. It is a dissociative anesthetic drug with psychostimulant and hallucinogenic effects. It is similar in effects to phencyclidine (PCP) but is considerably more potent.
