Japanese Persimmon and Pargyline

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Pargyline

Pargyline falls under ANTIHYPERTENSIVE DRUGS — the group Japanese Persimmon interacts with.

Japanese persimmon is thought to have hypotensive effects. Theoretically, concurrent use might increase risk of hypotension with drugs that lower blood pressure. These include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.
Severity Moderate Likelihood Probable Evidence B

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the simple version: Pargyline is an older blood pressure medicine (an MAO inhibitor that was sold as Eutonyl), so its whole job is to bring your blood pressure down. Japanese persimmon may have a mild blood-pressure-lowering effect of its own. Stack the two together and you could end up too low, which can leave you dizzy, lightheaded, faint, or wobbly when you stand up quickly.

This is mostly a theoretical concern based on limited human data, and eating a persimmon or two as fruit is unlikely to cause trouble. Concentrated persimmon supplements or leaf extracts are where I'd be more careful. Pargyline already needs close monitoring, so please check with your pharmacist or doctor before adding any persimmon product, and don't change your medication on your own.
