Abstract:
The use of atypical antipsychotic medication is increasing, with an increase in reported side-effects. The first reported case of quetiapine and citalopram-associated serotonin syndrome is discussed with reference to a Medline, Embase, and PsycINFO literature search. The putative aetiological mechanism is supersensitivity of 5-HT(1A) receptors (quetiapine) within an environment of increased synaptic available serotonin (citalopram). The symptom profile of serotonin syndrome overlaps with neuroleptic malignant syndrome, but can be reliably differentiated using a time and toxicity scale.

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...
