      Drug Name Selegiline Tapentadol
      Mechanism 1 Serotonergic effects
Monoamine oxidase non-selective  Inhibitor
Serotonergic effects
Serotonin transporter  Inhibitor
      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
Uniprot ID SC6A4_HUMAN
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.

      Mechanism Description
  • Additive serotonergic effects by the combination of Selegiline and Tapentadol

      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.
      Mechanism Description
  • Increased risk of lowers seizure threshold by the combination of Selegiline and Tapentadol 

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.
