Identification
- Summary
Nefazodone is an antidepressant used in the treatment of depression.
- Generic Name
- Nefazodone
- DrugBank Accession Number
- DB01149
- Background
Nefazodone hydrochloride (trade name Serzone) is an antidepressant drug marketed by Bristol-Myers Squibb. Its sale was discontinued in 2003 in some countries, due to the small possibility of hepatic (liver) injury. Drug-induced hepatic injuries were associated with an risk of elevated need for a liver transplant, or even death, with the incidence of severe liver damage was shown to be approximately 1 in 250,000 to 300,000 patient-years. On May 20, 2004, Bristol-Myers Squibb discontinued the sale of Serzone in the United States.

Nefazodone, an antidepressant synthetically derived phenylpiperazine, is used to treat major depression. Although it is structurally similar to trazodone, nefazodone has a mechanism of action different from other antidepressants and, hence, lacks the risk for major cardiovascular toxicity seen with tricyclics and insomnia and inhibition of REM sleep seen with the selective serotonin reuptake inhibitors.
- Mechanism of action
Within the serotonergic system, nefazodone acts as an antagonist at type 2 serotonin (5-HT2) post-synaptic receptors and, like fluoxetine-type antidepressants, inhibits pre-synaptic serotonin (5-HT) reuptake. These mechanisms increase the amount of serotonin available to interact with 5-HT receptors. Within the noradrenergic system, nefazodone inhibits norepinephrine uptake minimally. Nefazodone also antagonizes alpha(1)-adrenergic receptors, producing sedation, muscle relaxation, and a variety of cardiovascular effects. Nefazodone's affinity for benzodiazepine, cholinergic, dopaminergic, histaminic, and beta or alpha(2)-adrenergic receptors is not significant.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The metabolism of 1,2-Benzodiazepine can be decreased when combined with Nefazodone. Abacavir Abacavir may decrease the excretion rate of Nefazodone which could result in a higher serum level. Abametapir The serum concentration of Nefazodone can be increased when it is combined with Abametapir. Abatacept The metabolism of Nefazodone can be increased when combined with Abatacept. Abciximab The risk or severity of hemorrhage can be increased when Nefazodone is combined with Abciximab. - Food Interactions
