nefazodone profile

Nefazodone is a serotonin antagonist and reuptake inhibitor (SARI) antidepressant that was marketed under the brand name Serzone. It is chemically distinct from other antidepressants and has a unique mechanism of action. Nefazodone is thought to exert its antidepressant effects by blocking the reuptake of serotonin and norepinephrine, as well as by antagonizing serotonin receptors. The drug was synthesized in the 1970s and was approved by the Food and Drug Administration (FDA) in 1994 for the treatment of major depressive disorder. It was widely used for several years, but its use declined after concerns about its potential for liver toxicity were raised. Nefazodone is no longer marketed in the United States, but it remains available in some other countries. Research on nefazodone continues, as it has been found to have potential therapeutic benefits in other conditions, such as anxiety disorders, chronic pain, and substance abuse. Studies are ongoing to better understand its mechanism of action and its potential therapeutic applications.'

Role	Description
antidepressant	Antidepressants are mood-stimulating drugs used primarily in the treatment of affective disorders and related conditions.
serotonergic antagonist	Drugs that bind to but do not activate serotonin receptors, thereby blocking the actions of serotonin or serotonergic agonists.
serotonin uptake inhibitor	A compound that specifically inhibits the reuptake of serotonin in the brain. This increases the serotonin concentration in the synaptic cleft which then activates serotonin receptors to a greater extent.
alpha-adrenergic antagonist	An agent that binds to but does not activate alpha-adrenergic receptors thereby blocking the actions of endogenous or exogenous alpha-adrenergic agonists. alpha-Adrenergic antagonists are used in the treatment of hypertension, vasospasm, peripheral vascular disease, shock, and pheochromocytoma.
analgesic	An agent capable of relieving pain without the loss of consciousness or without producing anaesthesia. In addition, analgesic is a role played by a compound which is exhibited by a capability to cause a reduction of pain symptoms.

Class	Description
N-arylpiperazine
N-alkylpiperazine
triazoles	An azole in which the five-membered heterocyclic aromatic skeleton contains three N atoms and two C atoms.
monochlorobenzenes	Any member of the class of chlorobenzenes containing a mono- or poly-substituted benzene ring in which only one substituent is chlorine.
aromatic ether	Any ether in which the oxygen is attached to at least one aryl substituent.

It also displays strong affinity to several dopaminergic receptors, but shows only weak antagonism at the dopamine D2 receptor, a receptor commonly thought to modulate neuroleptic activity. Agranulocytosis is a major adverse effect associated with administration of this agent.. clozapine : A benzodiazepine that is 5H-dibenzo[b,e][1,4]diazepine substituted by a chloro group at position 8 and a 4-methylpiperazin-1-yl group at position 11.

Obsessive-Compulsive Disorder An anxiety disorder characterized by recurrent, persistent obsessions or compulsions.
