Etoxadrol
Etoxadrol (CL-1848C) is a dissociative anaesthetic drug that has been found to be an NMDA antagonist and produce similar effects to PCP in animals. Etoxadrol, along with another related drug dexoxadrol, were developed as analgesics for use in humans, but development was discontinued in the late 1970s after patients reported side effects such as nightmares and hallucinations. Chemical structure Phenicyclidine (PCP), tenocyclidine (TCP), etoxadrol and its precursor, dexoxadrol have related chemical structures. These drugs all act similarly on the nervous system, acting as dissociative hallucinogens (meaning that they interfere with normal sensory signals, replacing them with hallucinations of any sensory modality) with anesthetic and analgesic properties. Pharmacodynamics Etoxadrol is a non-competitive NMDA receptor antagonist. It binds with high affinity to the PCP binding site on the NMDA receptor ( Ki = 107 nM, determined by the displacement of radiolabeled TCP). Normall ...

NMDA Antagonist
NMDA receptor antagonists are a class of drugs that work to antagonize, or inhibit the action of, the ''N''-Methyl-D-aspartate receptor (NMDAR). They are commonly used as anesthetics for animals and humans; the state of anesthesia they induce is referred to as dissociative anesthesia. Several synthetic opioids function additionally as NMDAR-antagonists, such as pethidine, levorphanol, methadone, dextropropoxyphene, tramadol and ketobemidone. Some NMDA receptor antagonists, such as ketamine, dextromethorphan (DXM), phencyclidine (PCP), methoxetamine (MXE), and nitrous oxide (N2O), are sometimes used as recreational drugs, for their dissociative, hallucinogenic, and euphoriant properties. When used recreationally, they are classified as dissociative drugs. Uses and effects NMDA receptor antagonists induce a state called dissociative anesthesia, marked by catalepsy, amnesia, and analgesia. Ketamine is a favored anesthetic for emergency patients with unknown medical history and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
