Baikal Skullcap and Azilsartan

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Azilsartan

Azilsartan falls under ANTIHYPERTENSIVE DRUGS — the group Baikal Skullcap interacts with.

Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that baicalein, a constituent of Baikal skullcap, might 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

Here's the simple version: Azilsartan (Edarbi) already lowers your blood pressure, and some lab and animal studies hint that Baikal skullcap (thanks to a compound called baicalein) may nudge blood pressure down too. Put them together and the worry is that the two could stack up, pushing your numbers lower than intended.

I want to be honest about the evidence, though. This is based on test-tube and animal research only, not solid human studies, so it's more of a theoretical caution than a proven problem. If the combination ever caused trouble, you might feel dizzy, lightheaded, tired, or woozy when standing up. If you'd like to try this herb, check with your pharmacist or doctor first and keep an eye on your blood pressure readings.

About Azilsartan

What Is Azilsartan Used For?

Brand name: Edarbi

Azilsartan medoxomil tablets — sold as both the generic Azilsartan Medoxomil and the brand Edarbi — are approved to treat high blood pressure (hypertension) in adults. Bringing blood pressure down lowers the risk of serious cardiovascular events, especially stroke and heart attack.

The medication can be used on its own or alongside other blood pressure medicines. It is not a cure for high blood pressure, and managing the condition fully often involves lifestyle steps like limiting sodium, exercising, and quitting smoking.
