Tinospora Cordifolia and Mavacamten

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

Moderate

CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES

Why this applies to Mavacamten

Mavacamten falls under CYTOCHROME P450 2C19 (CYP2C19) SUBSTRATES — the group Tinospora Cordifolia interacts with.

Theoretically, Tinospora cordifolia might increase levels of drugs metabolized by CYP2C19.
In vitro research shows that Tinospora cordifolia extract inhibits CYP2C19 at high concentrations. However, this interaction has not been reported in humans.
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 situation with Camzyos (mavacamten) and Giloy. Your body clears mavacamten partly through a liver enzyme called CYP2C19. Lab studies hint that Tinospora cordifolia may slow that enzyme down. If that happened in a person, mavacamten could build up in your blood, and since it's not a prodrug, more drug means stronger effects.

Why that matters: mavacamten lowers how hard your heart squeezes, so too much can drop that function too far, leaving you tired, short of breath, dizzy, or with swelling. This concern comes only from test-tube research at high doses, not real people, so it's theoretical. Still, because mavacamten is carefully dose-adjusted, please check with your cardiologist or pharmacist before adding Giloy.

From our pharmacist’s overview on the Mavacamten page

“Grapefruit is the first thing I would set aside for anyone taking mavacamten (Camzyos), the medicine for obstructive hypertrophic cardiomyopathy. It blocks CYP3A4, the liver enzyme that clears mavacamten, and too much of this drug can weaken the heart's pumping strength, the very problem careful dosing exists to prevent.”
