Introduction:
Trazodone is a unique antidepressant, which blocks the postsynaptic serotonin (5-HT) receptors, 5-HT(2A) and 5-HT(2C), and weakly inhibits presynaptic 5-HT transporters.
Discussion:
Trazodone is well-absorbed by the mouth and is metabolized by three cytochromes: CYP1A2, CYP2D6, and CYP3A4. Clinical benefits include reduced insomnia in those depressed and/or on antidepressants. Pain may be relieved by mechanisms similar to venlafaxine. Delirium unresponsive to neuroleptics has been reported to respond to trazodone. Drug interactions are a risk due to cytochrome metabolism.
Conclusion:
Trazodone has a unique pharmacology, which may be an advantage in palliating symptoms; however, little evidence is available through cohort or randomized trials to give guidance to its use.

Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...
