General information

Substance class description

Psychedelics

• 2C-T-x is a moderate MAO-A inhibitor, can cause Serotonin Syndrome when combined with monoamine releasers, SSRIs or other MAO inhibitors.
  • https://www.ncbi.nlm.nih.gov/pubmed/15801832

• αMT is a reversible MAOI in higher doses (the danger rises exponentially as αMT doses approach 150 mg due to increased monoamine release and increased MAO inhibition), can cause Serotonin Syndrome when combined with monoamine releasers, SSRIs or other MAO inhibitors.
  • https://www.ncbi.nlm.nih.gov/pubmed/13851725
  • https://www.jstage.jst.go.jp/article/jphs1951/41/2/41_2_191/_article
  • https://www.ncbi.nlm.nih.gov/pubmed/13898151

• 5-MeO substituted tryptamines are SNRIs or SNDRIs and therefore should not be combined with other reuptake inhibitors or MAOIs.

  • http://www.ncbi.nlm.nih.gov/pubmed/16356341

Opioids

• Tramadol acts as a μ-opioid receptor agonist, serotonin releasing agent (SRA), serotonin and norepinephrine reuptake inhibitor (SNRI), NMDA receptor antagonist, 5-HT2C receptor antagonist, 5 nicotinic acetylcholine receptor antagonist, TRPV1 receptor agonist, and M1 and M3 muscarinic acetylcholine receptor antagonist. It can cause seizures, serotonin syndrome and even death when combined with certain stimulants and other reuptake inhibitors.
