Tranylcypromine (Parnate) - MOA, Dosage, Side effects

Tranylcypromine (Parnate) is a non-selective and irreversible monoamine oxidase inhibitor that is used in the treatment of anxiety and unipolar major depression.

Tranylcypromine Uses:

  • Unipolar Major depressive disorder:

    • Used for treatment of major depressive disorder in adult patients who have not responded adequately to other antidepressants.

Tranylcypromine Dose in Adults

Tranylcypromine Dose in the treatment of the Unipolar major depressive disorder:

P/O: Initial:

  • 10 to 30 mg per day, in divided doses
  • If symptoms don't improve after 2 weeks, increase the dose by 10 mg/day increments at 1- to 3-week intervals
  • Maximum dose: 60 mg/day
  • Usual dosage range 30 to 60 mg/day in divided doses.
  • Discontinuation of therapy:

    • After stopping antidepressant therapy after more than three weeks, taper the dosage gradually (for instance, over two to four weeks) to reduce withdrawal symptoms and spot recurrence of symptoms.
    • The usage of a medication with a half-life of less than 24 hours (such as paroxetine or venlafaxine), a history of antidepressant withdrawal symptoms, or high antidepressant doses are only a few reasons to gradually titrate the medication (for example, over a period of four weeks).
    • The severity of the MAOI-related symptoms necessitates more cautious tapering.
    • If uncomfortable withdrawal symptoms appear, you should either resume taking the medication at the original recommended dosage or reduce it more gradually.
    • Selected people receiving long-term treatment (>6 months) may benefit from tapering over time, such as those with a history of discontinuation syndrome.
    • Data supporting ideal taper rates is limited.
    • MAO inhibitor recommendations:
  • Switching to or from an MAO inhibitor intended to treat psychiatric disorders:

    • An alternative antidepressant without extended half-life metabolites (TCAs, paroxetine, fluvoxamine, venlafaxine, etc.) or MAO inhibitor used to treat psychiatric illnesses should be stopped 14 days before starting tranylcypromine.
    • Transcypromine should be started at least 5 to 6 weeks after fluoxetine, which has long-lasting metabolites and is used to treat psychiatric problems, has been stopped.
    • Tranylcypromine should be stopped at least 7 to 14 days before starting a different antidepressant or MAO inhibitor designed to treat psychiatric problems.

Tranylcypromine Dose in Children

Not indicated for use in children.

Tranylcypromine Pregnancy Risk Category: Not Assigned

Use of tranylcypromine during breastfeeding

Warnings and precautions

  • Depression in the CNS:

    • CNS depression can lead to impairment of mental or physical abilities. Patients must be careful when operating machinery or driving.

    • All patients should be monitored closely for BP; if there is any palpitation or frequent headaches, stop immediately.
    • An underlying hypertensive crisis can be disguised by a history of headaches.
    • This may occur when you consume foods/supplements high in tryptophan, tryptophan, and phenylalanine.
    • Patients who have not consumed tyramine-rich foods and beverages have had clinically significant increases in BP.
  • Hypotension

    • Orthostatic hypotension may occur, especially at doses greater than 30 mg/day. It may also cause syncope.
    • Patients with hypotension should be given a gradual increase in dosage.
  • Intracranial bleeding

    • Intestinal bleeding, sometimes fatal, has been linked to the paradoxical rise in BP.
  • Serotonin syndrome

    • Particularly when combined with other serotonergic medications (such as triptans TCAs, fentanyl and buspirone, lithium, tramadol, or tramadol), or substances that impair serotonin metabolism (such as MAO inhibitors to treat psychiatric conditions, other MAO inhibitors [i.e. linezolid, intravenous methylene]), serotonergic drugs (such as SSRIs and SNRIs)
    • Take attention to SS warning indicators like
      • Mental status changes (eg: agitation, hallucinations and delirium, coma, etc.)

      • Neuromuscular changes (eg tremors, rigidity, myoclonus, etc.)
      • GI symptoms (eg nausea, vomiting, diarrhea)
      • And/or seizures
    • Stop taking any serotonergic agents or treatment if you notice signs or symptoms.
  • Cardiovascular disease

    • Patients with severe hypertension, cerebrovascular disease or other cardiovascular conditions should be treated cautiously.
  • Diabetes:

    • Diabetes patients should be cautious. It may increase the chance of hypoglycemic episodes.
    • Patients who are taking insulin or oral hypoglycemic drugs should closely monitor their blood glucose.
  • Use of drugs:

    • Patients with a history of drug abuse or acute drinking problems should be cautious.
    • There may be a risk of developing drug dependence, particularly if the dose is higher than prescribed.
  • Hepatic impairment

    • Cirrhosis patients must be continuously watched for any possible negative effects on the central nervous system, such as tiredness and sedation.
    • Patients with hepatitis or elevated aminotransferases may develop. Stop taking this medication if you have hepatotoxicity.
  • Hypomania and mania:

    • Patients with bipolar disorder can experience mania or hypomania.
    • Bipolar patients should refrain from monotherapy.
    • A patient should be checked if they exhibit depressive symptoms.
    • Tranylcypromine is not used to treat bipolar depression.
