WebOct 6, 2024 · SSRI/5HT-1A partial agonists increase the levels of serotonin and also enhance the activity of a specific type of serotonin receptors known as 5HT-1A receptors. Serotonin is an important natural chemical ( neurotransmitter ) released by nerve cells (neurons) in the brain to transmit nerve signals.
Fluoxetine acts as a direct 5-HT 2C antagonist in addition to inhibiting serotonin reuptake, however, the clinical significance of this action is variable. Several tetracyclic antidepressants , including mirtazapine , are potent 5-HT 2C antagonists; this action may contribute to their efficacy.
