Identification
- Summary
Tranylcypromine is a monoamine oxidase inhibitor used to treat major depressive disorder.
- Brand Names
- Parnate
- Generic Name
- Tranylcypromine
- DrugBank Accession Number
- DB00752
- Background
A propylamine formed from the cyclization of the side chain of amphetamine. This monoamine oxidase inhibitor is effective in the treatment of major depression, dysthymic disorder, and atypical depression. It also is useful in panic and phobic disorders (From AMA Drug Evaluations Annual, 1994, p311).
Tranylcypromine is a racemate comprising equal amounts of (1R,2S)- and (1S,2R)-2-phenylcyclopropan-1-amine with the chiral centers both located on the cylopropane ring. An irreversible monoamine oxidase inhibitor that is used as an antidepressant (INN tranylcypromine).

- Pharmacodynamics
Tranylcypromine belongs to a class of antidepressants called monoamine oxidase inhibitors (MAOIs). Tranylcypromine is a non-hydrazine monoamine oxidase inhibitor with a rapid onset of activity. MAO is an enzyme that catalyzes the oxidative deamination of a number of amines, including serotonin, norepinephrine, epinephrine, and dopamine. Two isoforms of MAO, A and B, are found in the body. MAO-A is mainly found within cells located in the periphery and catalyzes the breakdown of serotonin, norepinephrine, epinephrine, dopamine and tyramine. MAO-B acts on phenylethylamine, norepinephrine, epinephrine, dopamine and tyramine, is localized extracellularly and is found predominantly in the brain. While the mechanism of MAOIs is still unclear, it is thought that they act by increasing free serotonin and norepinephrine concentrations and/or by altering the concentrations of other amines in the CNS. It has been postulated that depression is caused by low levels of serotonin and/or norepinephrine and that increasing serotonergic and norepinephrinergic neurotransmission results in relief of depressive symptoms. MAO A inhibition is thought to be more relevant to antidepressant activity than MAO B inhibition. Selective MAO B inhibitors, such as selegiline, have no antidepressant effects.
- Mechanism of action
Tranylcypromine irreversibly and nonselectively inhibits monoamine oxidase (MAO). Within neurons, MAO appears to regulate the levels of monoamines released upon synaptic firing. Since depression is associated with low levels of monoamines, the inhibition of MAO serves to ease depressive symptoms, as this results in an increase in the concentrations of these amines within the CNS.
Target Actions Organism AAmine oxidase [flavin-containing] B inhibitorHumans AAmine oxidase [flavin-containing] A inhibitorHumans - Absorption
Interindividual variability in absorption. May be biphasic in some individuals. Peak plasma concentrations occur in one hour following oral administration with a secondary peak occurring within 2-3 hours. Biphasic absorption may represent different rates of absorption of the stereoisomers of the drug, though additional studies are required to confirm this.

- Toxicity
In overdosage, some patients exhibit insomnia, restlessness and anxiety, progressing in severe cases to agitation, mental confusion and incoherence. Hypotension, dizziness, weakness and drowsiness may occur, progressing in severe cases to extreme dizziness and shock. A few patients have displayed hypertension with severe headache and other symptoms. Rare instances have been reported in which hypertension was accompanied by twitching or myoclonic fibrillation of skeletal muscles with hyperpyrexia, sometimes progressing to generalized rigidity and coma.

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The risk or severity of CNS depression can be increased when Tranylcypromine is combined with 1,2-Benzodiazepine. Abaloparatide Tranylcypromine may increase the orthostatic hypotensive activities of Abaloparatide. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Tranylcypromine is combined with Abciximab. Abrocitinib The metabolism of Abrocitinib can be decreased when combined with Tranylcypromine. Acarbose Tranylcypromine may increase the hypoglycemic activities of Acarbose. - Food Interactions
- Avoid alcohol. Ingesting alcohol may increase the CNS depressant effects of tranylcypromine.
- Avoid St. John's Wort. Administering tranylcypromine with St. John's Wort may increase the risk of serotonin syndrome.
- Avoid tyramine-containing foods and supplements. Tyramine-containing foods and beverages can cause a sudden elevation in blood pressure or a hypertensive crisis. Foods that contain tyramine include aged cheese, ripe bananas, red wine, some alcoholic beverages (beer), cured food, pickled food, and fava beans.
