| Mechanism |
Serotonergic effects Monoamine oxidase non-selective Inhibitor |
Serotonergic effects 5-HT 3 receptor Antagonist |
|||||||
| Key Mechanism Factor 1 | |||||||||
| Factor Name | Monoamine oxidase | Structure Sequence | |||||||
| Protein Family | Flavin monoamine oxidase family | ||||||||
| Protein Function |
Catalyzes the oxidative deamination of primary and some secondary amine such as neurotransmitters, with concomitant reduction of oxygen to hydrogen peroxide and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues (PubMed:20493079, PubMed:8316221, PubMed:18391214, PubMed:24169519). Preferentially oxidizes serotonin (PubMed:20493079, PubMed:24169519). Also catalyzes the oxidative deamination of kynuramine to 3-(2-aminophenyl)-3-oxopropanal that can spontaneously condense to 4-hydroxyquinoline (By similarity).

| Key Mechanism Factor 2 | |||||||||
| Factor Name | 5-HT 3 receptor | Structure Sequence | |||||||
| Protein Family | Ligand-gated ion channel (TC 1.A.9) family | ||||||||
| Protein Function |
This is one of the several different receptors for 5-hydroxytryptamine (serotonin), a biogenic hormone that functions as a neurotransmitter, a hormone, and a mitogen. This receptor is a ligand-gated ion channel, which when activated causes fast, depolarizing responses in neurons. It is a cation-specific, but otherwise relatively nonselective, ion channel.

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | Caution is advised if 5-HT3 receptor antagonists are prescribed with other agents that affect the serotonergic neurotransmitter system. Patients should be closely monitored for symptoms of the serotonin syndrome during treatment. Particular caution is warranted when initiating or increasing the dosages of these agents. The potential risk for serotonin syndrome should be considered even when administering serotonergic agents sequentially, as some agents may demonstrate a prolonged elimination half-life. For example, a 5-week washout period is typically recommended following use of fluoxetine and 2 weeks following use of MAOIs before administering another serotonergic agent. If serotonin syndrome develops or is suspected during the course of therapy, all serotonergic agents should be discontinued immediately and supportive care rendered as necessary. | ||||||||
