Khat and Enalapril Maleate

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Enalapril Maleate

Enalapril Maleate falls under ANTIHYPERTENSIVE DRUGS — the group Khat interacts with.

Human research shows that khat and its constituent, cathinone, can increase blood pressure. Theoretically, khat might reduce the effect of antihypertensive drug therapy. Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.
Severity Moderate Likelihood Possible Evidence B

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

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

Here's the simple version: enalapril (Vasotec) lowers your blood pressure by relaxing your blood vessels. Khat does the opposite. Its main chemical, cathinone, acts a lot like amphetamine and pushes your blood pressure and heart rate up. So the two are basically fighting each other, and khat can blunt the benefit you're getting from your enalapril.

In real terms, that could mean your numbers stay higher than they should, even though you're taking your medicine faithfully. On top of that, khat is a controlled substance and is illegal in the U.S., and it carries its own heart and mental health risks. Please don't start or stop anything on your own, and talk with your pharmacist or doctor about keeping your blood pressure well controlled.

From our pharmacist’s overview on the Enalapril Maleate page

“Potassium is the supplement I worry about first with enalapril maleate (Vasotec, Epaned). This ACE inhibitor, used for high blood pressure and heart failure, already makes the body hold onto potassium, so adding more can raise blood levels too far, a problem called hyperkalemia.”

About Khat

What is Khat?

Khat
  • Stimulant for energy and alertness
  • Euphoria and mood elevation
  • Reducing fatigue
  • Appetite suppression
  • Social and traditional ceremonies

Khat is a plant chewed for its amphetamine-like stimulant effects, but it carries serious risks including high blood pressure, heart problems, mental health effects, and dependence. It is a controlled substance and illegal in the United States and many other countries, so it should not be used.

About Enalapril

What Is Enalapril Used For?

Brand names: Vasotec, Epaned

Enalapril is used to treat high blood pressure (hypertension) in adults and children older than one month, and to treat symptomatic heart failure. Lowering blood pressure reduces the risk of stroke and heart attack.

It is also used for asymptomatic left ventricular dysfunction — when the heart's pumping ability is reduced but the person doesn't yet have obvious heart failure symptoms — to slow the progression to overt heart failure and reduce hospitalizations. Enalapril maleate oral solution (including Epaned) and enalapril maleate tablets (including Vasotec) share these three approved uses.
