Warning(s)

  • Suicidality
  • Antidepressants may increase risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (18–24 years of age) with major depressive disorder and other psychiatric disorders; balance this risk with clinical need.101 103 104 a Tranylcypromine is not approved for use in pediatric patients.101 a (See Pediatric Use under Cautions.)

  • In pooled data analyses, risk of suicidality was not increased in adults >24 years of age and apparently was reduced in adults ≥65 years of age with antidepressant therapy compared with placebo.101 103 104 a

  • Depression and certain other psychiatric disorders are themselves associated with an increased risk of suicide.101 103 104 105 a

  • Appropriately monitor and closely observe all patients who are started on tranylcypromine therapy for clinical worsening, suicidality, or unusual changes in behavior; involve family members and/or caregivers in this process.101 103 104 105 a (See Worsening of Depression and Suicidality Risk and Pediatric Use under Cautions.)

Slideshow: Multiple Sclerosis: What's New in Treatment Options?

MAO inhibitors appear particularly effective in treatment of major depressive disorder with atypical features, although other antidepressants (e.g., SSRIs) may initially be used because of their more favorable adverse effect profile.102 e f

Because of potential for serious adverse effects and necessity of dietary restrictions, MAO inhibitors (e.g., phenelzine, tranylcypromine) generally are not used as initial therapy for major depressive disorder, but are reserved for carefully selected patients who can be closely supervised and who have depression refractory to other antidepressants (e.g., SSRIs, SNRIs, TCAs) or in whom other therapies are contraindicated.101 102 a d e f

Warnings/Precautions

Warnings

Shares the toxic potentials of other MAO inhibitors; observe the usual precautions and contraindications associated with therapy with these drugs.d e Should be used only by clinicians who are completely familiar with proper use, potential adverse effects, and associated precautions and contraindications of MAO inhibitors.101 a d e Fully advise patients about risks, especially hypertensive crisis and suicidal thinking and behavior (suicidality), associated with MAO inhibitor therapy.101 a d e

Worsening of Depression and Suicidality Risk

Possible worsening of depression and/or emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior in both adult and pediatric patients with major depressive disorder, whether or not they are taking antidepressants; may persist until clinically important remission occurs.101 103 104 105 106 a However, suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide.101 103 104 105 a

Appropriately monitor and closely observe patients receiving tranylcypromine for any reason, particularly during initiation of therapy (i.e., the first few months) and during periods of dosage adjustments.101 103 104 105 a (See Boxed Warning and also see Pediatric Use under Cautions.)

Anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia, hypomania, and/or mania may be precursors to emerging suicidality.101 104 105 a Consider changing or discontinuing therapy in patients whose depression is persistently worse or in those with emerging suicidality or symptoms that might be precursors to worsening depression or suicidality, particularly if severe, abrupt in onset, or not part of patient’s presenting symptoms.103 104 105

Prescribe in smallest quantity consistent with good patient management to reduce risk of overdosage.101 104 a

Observe these precautions for patients with psychiatric (e.g., major depressive disorder, obsessive-compulsive disorder) or nonpsychiatric disorders.101 104 a

Bipolar Disorder

May unmask bipolar disorder.101 104 a (See Activation of Mania or Hypomania under Cautions.) Tranylcypromine is not approved for use in treating bipolar depression.101 a

Screen for risk of bipolar disorder by obtaining detailed psychiatric history (e.g., family history of suicide, bipolar disorder, depression) prior to initiating therapy.101 104 a

Hypertensive Crises

Hypertensive crises, sometimes fatal, are one of the most serious adverse effects associated with MAO inhibitors, including tranylcypromine.101 102 a e Although spontaneous cases reported, most cases occurred following ingestion of foods or beverages containing large amounts of tyramine (i.e., cheese reaction) or when MAO inhibitors were used concomitantly with certain prescription or OTC drugs.101 a e (See Specific Drugs and Foods under Interactions and see also Advice to Patients.)

Characterized by occipital headache (which may radiate frontally), palpitation, neck stiffness or soreness, nausea or vomiting, sweating (sometimes with fever or cold, clammy skin), mydriasis and/or visual disturbances (e.g., photophobia).101 102 a e Tachycardia or bradycardia with associated constricting chest pain and dilated pupils and intracranial hemorrhage, sometimes fatal, also reported.101 102 a e

Closely monitor BP in all patients to detect evidence of pressor response; however, full reliance should not be placed on BP determinations alone.101 a e Frequently observe patient’s clinical status, particularly for signs and symptoms of hypertension.101 a e

If a hypertensive crisis or prodromal signs of hypertensive crisis occur, discontinue MAO inhibitor therapy and immediately institute appropriate therapy to lower BP.101 a e Phentolamine considered hypotensive drug of choice for treating MAO inhibitor-induced hypertensive crisis.101 102 a e Manage fever by external cooling.101 a e Other symptomatic and supportive measures may be necessary in some patients; however, avoid administration of parenteral reserpine.101 a e (See Contraindications under Cautions and see Specific Drugs and Foods under Interactions.)

General Precautions

Activation of Mania or Hypomania

Possible activation of mania and hypomania, particularly in patients with bipolar disorder.101 a (See Bipolar Disorder under Cautions.)

Orthostatic Hypotension

Possible hypotension.100 101 a e Postural hypotension symptoms most commonly observed in patients with preexisting hypertension.101 a e BP generally returns rapidly to pretreatment levels upon drug discontinuance.101 a

At dosages >30 mg daily, postural hypotension is an important adverse effect and may cause syncope.101 a In patients who show some hypotensive response during initiation of MAO inhibitor therapy, increase dosage more gradually.101 a e May relieve postural hypotension by having patient lie down until BP returns to normal.101 a e

Myelography

Avoid concurrent use of drugs that lower seizure threshold, including MAO inhibitors, and metrizamide (no longer commercially available in US).101 a e Discontinue tranylcypromine ≥48 hours prior to myelography; do not resume therapy for ≥24–48 hours post-procedure.101 a e (See Specific Drugs and Foods under Interactions.)

Cardiovascular Effects

MAO inhibitors may suppress anginal pain that would otherwise serve as a warning sign of myocardial ischemia; warn patients with angina pectoris or coronary artery disease against overexertion.101 a e

Endocrine and Metabolic Effects

MAO inhibitors may cause hypoglycemic episodes in diabetic patients receiving insulin or oral antidiabetic agents; use tranylcypromine with caution in diabetic patients receiving these drugs concurrently.101 a e

Use MAO inhibitors with caution in patients with hyperthyroidism, since these patients have an increased sensitivity to pressor amines.101 a e

Nervous System Effects

Possible aggravation of coexisting depressive symptoms, such as anxiety and agitation.101 a e (See Worsening of Depression and Suicidality Risk under Cautions.)

Overstimulation, including increased anxiety, agitation, and manic symptoms, may occur and usually indicates excessive therapeutic action; consider tranylcypromine dosage reduction or addition of antipsychotic (e.g., phenothiazine) therapy.101 a (See Specific Drugs and Foods under Interactions.)

Seizures

MAO inhibitors have a variable effect on the seizure threshold; use with caution in patients with a seizure disorder.101 a e

Dependence and Withdrawal of Therapy

Drug dependence reported in patients receiving tranylcypromine dosages substantially in excess of usual therapeutic range; some of these patients had a history of previous substance abuse.101 a e o Withdrawal symptoms reported include restlessness, anxiety, depression, confusion, hallucinations, headache, weakness, and diarrhea.101 a e

Specific Populations

Pregnancy

Category C.j

Lactation

Distributes into milk.101 a Caution if used in nursing women.e

Pediatric Use

Safety and efficacy in pediatric patients not established.101 a

FDA warns that a greater risk of suicidal thinking or behavior (suicidality) occurred during first few months of antidepressant treatment (4%) compared with placebo (2%) in children and adolescents with major depressive disorder, obsessive-compulsive disorder (OCD), or other psychiatric disorders based on pooled analyses of 24 short-term, placebo-controlled trials of 9 antidepressant drugs (SSRIs and others).101 104 a However, a more recent meta-analysis of 27 placebo-controlled trials of 9 antidepressants (SSRIs and others) in patients <19 years of age with major depressive disorder, OCD, or non-OCD anxiety disorders suggests that the benefits of antidepressant therapy in treating these conditions may outweigh the risks of suicidal behavior or suicidal ideation.106 No suicides occurred in these pediatric trials.101 104 106 a

Carefully consider these findings when assessing potential benefits and risks of tranylcypromine in a child or adolescent for any clinical use.101 103 104 105 106 a (See Worsening of Depression and Suicidality Risk under Cautions.)

Geriatric Use

Clinical experience with MAO inhibitors has not identified any differences in responses between geriatric and younger adults.e

In pooled data analyses, a reduced risk of suicidality was observed in adults ≥65 years of age with antidepressant therapy compared with placebo.101 103 104 a (See Boxed Warning and also see Worsening of Depression and Suicidality Risk under Cautions.)

Possible increased morbidity during or following episodes of hypertension or malignant hyperthermia; geriatric patients have less compensatory reserve to cope with any serious adverse reaction.101 a e

Use with caution.101 a e

Hepatic Impairment

Contraindicated in patients with history of hepatic disease or abnormal liver function test results.101 a e

Renal Impairment

Possible accumulation of tranylcypromine in plasma; use with caution.101 a e

Common Adverse Effects

Adverse nervous system effects (e.g., insomnia, dizziness, headache), GI effects (e.g., dry mouth, anorexia, nausea, diarrhea, abdominal pain, constipation), cardiovascular effects (e.g., orthostatic hypotension, hypertension, tachycardia, peripheral edema, palpitation), GU effects (e.g., impotence, delayed ejaculation, urinary retention), blurred vision, chills, weight gain.101 102 a e

Parnate Pharmacokinetics

Absorption

Bioavailability

Rapidly absorbed following single-dose (20 mg), oral administration, with peak plasma tranylcypromine concentrations of approximately 110 ng/mL (range: 65–190 ng/mL) achieved within approximately 1.5 hours (range: 0.7–3.5 hours).100 d f k l GI absorption demonstrates interindividual variation and may be biphasic in some individuals.100 d f

Onset

Pharmacologic effects of MAO inhibitors are cumulative; onset of pharmacologic action of tranylcypromine is more rapid than that of hydrazine-derivative MAO inhibitors (e.g., phenelzine).d e Antidepressant effect usually evident within 2 days–3 weeks.101 a e

Duration

Inhibition of MAO may persist up to 10 days following drug discontinuance.101 a

Distribution

Extent

Crosses placenta in rats.101 a Distributes into human milk.101 a

Elimination

Metabolism

Rapidly and extensively metabolized following oral administration.k

Elimination Route

Excretion is rapid, occurring within 24 hours after drug discontinuance; however, urinary tryptamine concentrations, which are used to measure MAO activity, return to normal within 72–120 hours.100 101 a d l

Half-life

Elimination half-life averages 2.5 hours (range: 1.5–3.2 hours).100 d f k l

Stability

Storage

Oral

Tablets

Well closed, light-resistant containers at 20–25°C (may be exposed to 15–30°C).101 a d

Actions

  • Principal pharmacologic effects of tranylcypromine are similar to those of other nonselective MAO inhibitors (e.g., phenelzine).d e

  • Tranylcypromine binds reversibly to the MAO enzyme while phenelzine binds irreversibly to the enzyme.e

  • Precise mechanism of antidepressant action is unknown but may involve increases in free serotonin and norepinephrine and/or alterations in other amine concentrations within the CNS.101 a e f 100

Advice to Patients

  • Risk of suicidality; importance of patients, family, and caregivers being alert to and immediately reporting emergence of suicidality, worsening depression, or unusual changes in behavior, especially during the first few months of therapy or during periods of dosage adjustment.101 103 104 105 a FDA recommends providing written patient information (medication guide) explaining risks of suicidality each time the drug is dispensed.101 103 104 105 a

  • Risk of serious adverse effects (e.g., hypertensive reactions).101 a e Importance of promptly informing clinicians if headache or other unusual symptoms (e.g., palpitation and/or tachycardia, constriction in throat or chest, sweating, dizziness, neck stiffness, nausea or vomiting) occur.101 a e

  • Importance of informing patients to avoid foods and beverages with a high tyramine content.101 a

  • Importance of informing patients to avoid excessive use of caffeine in any form.101 a

  • Importance of informing patients to avoid alcoholic beverages.101 a

  • Risk of hypotension, faintness, and drowsiness.101 a e Importance of considering possible impaired ability to perform hazardous activities (e.g., operating machinery, driving a motor vehicle).101 a

  • Importance of patients informing their clinicians and dentist that they are taking tranylcypromine.101 a

  • Importance of women informing their clinician if they are or plan to become pregnant or plan to breast-feed.101 a

  • Importance of informing clinicians of existing or contemplated concomitant therapy, including prescription and OTC drugs and herbal or nutritional supplements, as well as any concomitant illnesses.101 a

  • Importance of informing patients of other important precautionary information.101 a (See Cautions.)
