Phenelzine and Tyramine / High-Tyramine Foods: what the research found

PubMed indexes 7 records that name Phenelzine and Tyramine / High-Tyramine Foods together, either in the title or in an interaction, co-administration, or pharmacokinetic context. The key findings come first, in the authors’ own words, followed by every study with its design and PubMed link.

A summary of published research, not medical advice. A pharmacist can check any combination against your full list of medicines and supplements.

Key findings

What the studies concluded.

Reviews and human studies first. Each quote is the authors’ own conclusion about their study, not a NutriStack assessment, and a single study is not a consensus.

“The nonsignificant decrease of MHPG excretion and the increase of intravenous tyramine pressor sensitivity caused by phenelzine are significantly related. The data suggest that the selective reversible MAO-A inhibitor brofaromine has a larger therapeutic safety than phenelzine.”

Bieck et al. · 1989 · Human study · details

“Results from preclinical and clinical investigations demonstrate that moclobemide and brofaromine, in contrast to tranylcypromine and phenelzine, very weakly potentiate the pressor effects of orally administered tyramine. In conclusion, the reversible MAO-A inhibitors moclobemide and brofaromine, due to their well-documented safety characteristics, to their lack of anticholinergic-effects and to their good…”

Da Prada et al. · 1989 · Human study · details

“The increased sensitivity after phenelzine persisted for longer than 8 weeks and after clorgyline for longer than 15 weeks. The results suggest that the two reversible MAO-A inhibitors moclobemide and brofaromine carry a much reduced liability to tyramine-related hypertensive reactions.”

Comparative StudyReviewHuman subjects

“Results from preclinical and clinical investigations demonstrate that moclobemide and brofaromine, in contrast to tranylcypromine and phenelzine, very weakly potentiate the pressor effects of orally administered tyramine. In conclusion, the reversible MAO-A inhibitors moclobemide and brofaromine, due to their well-documented safety characteristics, to their lack of anticholinergic-effects and to their good tolerability, will provide innovative tools for clarifying the role…”

Limitations

What this evidence cannot tell you.

Search-based evidence indexes have real limits, and it is worth being explicit about them:
