Gentian and Aprocitentan

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

ANTIHYPERTENSIVE DRUGS

Why this applies to Aprocitentan

Aprocitentan falls under ANTIHYPERTENSIVE DRUGS — the group Gentian interacts with.

Theoretically, taking gentian with antihypertensive drugs might increase the risk of hypotension.
In vitro research shows that gentian can cause vasodilation and lower blood pressure.
Severity Moderate Likelihood Possible Evidence D

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

Aprocitentan (Tryvio) is a newer medicine used to help lower blood pressure that is hard to control. Gentian, the bitter root often found in digestive bitters, has shown in lab studies that it may relax blood vessels and nudge blood pressure down a little. So the concern here is simple: two things pushing blood pressure in the same direction could, in theory, push it down a bit too far.

If that happened, you might feel dizzy, lightheaded, or tired, especially when standing up quickly. Keep in mind this warning comes from test-tube and animal research, not from people, so it is more of a caution than a proven problem. Small amounts of bitters before a meal are unlikely to cause trouble, but before adding concentrated gentian supplements, check with your pharmacist or doctor.

From our pharmacist’s overview on the Aprocitentan page

“Aprocitentan (Tryvio) is prescribed when blood pressure stays high despite other medicines, so anything that pushes your pressure around cuts straight to why you take it. Most of the 189 ingredients here do exactly that: some add to the drop and can leave you dizzy or faint, while others, tyramine among them, push pressure back up and…”

About Gentian

What is Gentian?

  • Loss of appetite
  • Indigestion and bloating
  • Digestive bitter tonic
  • Stomach upset
  • Sluggish digestion

Gentian is a very bitter root traditionally used to stimulate appetite and ease mild digestive complaints, often as part of "bitters" before meals. The evidence is mostly traditional and preliminary, and while short-term use of normal amounts appears generally well tolerated in healthy adults, anyone with ulcers, reflux, or who is pregnant should be cautious and check with a pharmacist or doctor first.

About Aprocitentan

What Is Aprocitentan Used For?

Brand name: Tryvio

Tryvio is used to treat high blood pressure (hypertension) in adults who are already taking other blood pressure medications but still don't have their blood pressure under control. It is always used in combination with other antihypertensive (blood pressure-lowering) drugs — not on its own.

Lowering blood pressure reduces the risk of serious cardiovascular events, including strokes and heart attacks. Tryvio has not been shown in controlled trials to directly reduce those events itself, but blood pressure control overall does.
