| 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).

| Gene Name | SLC6A4 | ||||||||

| KEGG Pathway | hsa:6532 | ||||||||
| Protein Family | Sodium:neurotransmitter symporter (SNF) (TC 2.A.22) family | ||||||||
| Protein Function |
Serotonin transporter whose primary function in the central nervous system involves the regulation of serotonergic signaling via transport of serotonin molecules from the synaptic cleft back into the pre-synaptic terminal for re-utilization. Plays a key role in mediating regulation of the availability of serotonin to other receptors of serotonergic systems. Terminates the action of serotonin and recycles it in a sodium-dependent manner.

| Drug Name | Selegiline | Tapentadol | |||||||
| Mechanism 2 | Lower seizure threshold | Lower seizure threshold | |||||||
| Key Mechanism Factor 3 | |||||||||
| Factor Name | Lowers seizure threshold | ||||||||
| Factor Description | The combination of medications that lower the seizure threshold is a factor that makes people with epilepsy more likely to have seizures. A seizure is a sudden, uncontrolled electrical disturbance in the brain that can cause changes in your behavior, movements or sensations, and level of consciousness. | ||||||||

| Recommended Action | |||||||||
|---|---|---|---|---|---|---|---|---|---|
| Management | The use of tapentadol in patients currently receiving or within 14 days of receiving a monoamine oxidase inhibitor (MAOI) is considered contraindicated. | ||||||||
