- Background
Phenelzine, with the formula β-phenylethylhydrazine, is a monoamine oxidase inhibiting antidepressant that is effective in the treatment of panic disorder and social anxiety disorder.3 It was developed by Parke Davis and originally FDA approved on June 9th, 1961. It is currently approved under prescription by the name of Nardil.

Pharmacology
- Indication
Phenelzine is indicated for the treatment of nonendogenous, neurotic or atypical depression for patients that do not tolerate other forms of therapy.12
Atypical depression has a high prevalence rate, starts in early life, tends to last longer, is more likely to occur in people with bipolar disorder, has a high comorbidity with anxiety disorder and carries more risk of suicidal behavior. It is important to specify the atypical feature to predict the clinical course of depression and hence generate the best treatment and service. The featuring symptoms of the atypical feature include mood reactivity, two or more of this symptoms: 1) increased appetite, 2) increased sleep, 3) leaden paralysis and 4) interpersonal rejection sensitivity and should not have melancholic or catatonic features of depression.4
Neurotic depression is a depression of an emotionally unstable person. It is a secondary condition to major personality disorder, neuroses and drug use disorders. Likewise, a primary depression with a family history of depression spectrum disease would fit in this category.5
A nonendogenous depression is characterized by a disturbance in mood and general outlook. The physical symptoms tend to be less severe and it often occurs in response to stressful life events that keep occurring over a large period of time generating a continuous stress in the daily living.6

- Pharmacodynamics
The elimination of monoamine oxidase by phenelzine results in the elevation of brain amines such as 2-phenylethylamine which is a metabolite of phenelzine. These amines have then marked effects on the uptake and release of catecholamines and serotonin in nerve endings.7 Phenelzine is shown to elevate brain levels of the gamma-aminobutyric acid (GABA) and alanine (ALA) as well as to inhibit the activity of the transaminases that normally metabolize these amino acids. In preclinical studies, it has been shown to be neuroprotective in cerebral ischemia.3
- Mechanism of action
The basic mechanism of action of phenelzine acts as an inhibitor and substrate of monoamine oxidase which subsequently causes an elevation in brain levels of catecholamines and serotonin. It also presents a similar structure to amphetamine which explains the effect on the uptake and release of dopamine, noradrenaline, and serotonin. Phenelzine has been reported to inhibit tyrosine aminotransferase, aromatic amino acid decarboxylase, and dopamine B-hydroxylase.7
Target Actions Organism AAmine oxidase [flavin-containing] A antagonistHumans AAmine oxidase [flavin-containing] B antagonistHumans UMembrane primary amine oxidase inhibitorHumans U4-aminobutyrate aminotransferase, mitochondrial inhibitorHumans UAlanine aminotransferase 1 inhibitorHumans UAlanine aminotransferase 2 inhibitorHumans UGlutamic acid decarboxylase inhibitorHumans - Absorption
Phenelzine is rapidly absorbed from the gastrointestinal tract. The decay of the drug action is not dependent on the pharmacokinetic parameters but on the rate of protein synthesis which restores the functional levels of monoamine oxidase.13 The mean Cmax is 19.8 ng/ml and it occurs after 43 minutes of dose administration.Label
- Volume of distribution
The volume of distribution of phenelzine is hard to determine as drugs from this kind penetrate the CNS very well into the tissue where their activity is desired.10
- Protein binding
Unchanged phenelzine presents a high protein binding which reduced its bioavailability.11
- Metabolism
For the metabolic studies, it is assumed that phenelzine is acetylated. Some of the metabolites of phenelzine are phenylacetic acid, 2-phenylethylamine and 4-hydroxyphenylacetic acid as major metabolites and N-acetyl-phenelzine as a minor metabolite.7

- Route of elimination
The elimination of the administered dose is mainly composed of the phenelzine metabolites, phenylacetic acid and parahydroxyphenylacetic acid that constitute 79% of the dose found in the urine in the first 96 hours.8
- Half-life
After administration phenelzine presents a very short half-life of 11.6 hours in humans.13

- Toxicity
Phenelzine, as must of the monoamine oxidase inhibitors, can cause transient, mild and asymptomatic aminotransferase elevations. It has also been reported to be associated with cases of liver injury after 1-3 months of treatment.9

Drug Interaction Integrate drug-drug
interactions in your software1,2-Benzodiazepine The risk or severity of CNS depression can be increased when Phenelzine is combined with 1,2-Benzodiazepine. Abacavir Phenelzine may decrease the excretion rate of Abacavir which could result in a higher serum level. Abaloparatide Phenelzine may increase the orthostatic hypotensive activities of Abaloparatide. Abciximab The risk or severity of bleeding and hemorrhage can be increased when Phenelzine is combined with Abciximab. Acarbose Phenelzine may increase the hypoglycemic activities of Acarbose. - Food Interactions
- Avoid alcohol.
- Avoid St. John's Wort. Administering phenelzine 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.
- Limit caffeine intake. Excess caffeine intake can also cause a hypertensive crisis.
