Abstract:
The tolerability and safety profile of the noradrenergic and specific serotonergic antidepressant (NaSSA) mirtazapine reflects its unique pharmacological profile. The 5-HT(2) blocking effect contributes towards its anxiolytic effects and benefits on sleep, as well as preventing the sexual dysfunction that may occur with non-specific stimulation of the serotonin system by drugs such as the selective serotonin reuptake inhibitors (SSRIs). In addition, 5-HT(3) blockade by mirtazapine helps to prevent nausea and vomiting. Weight gain is the most commonly reported side-effect of mirtazapine, although there is evidence to suggest that this is not a significant problem during long-term treatment. In conclusion, mirtazapine has a good tolerability and safety profile that demonstrates several benefits over other antidepressants.

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...
