Thunder God Vine and Selinexor

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Selinexor

Selinexor falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Thunder God Vine interacts with.

Theoretically, thunder god vine might increase the levels and clinical effects of CYP3A4 substrates.
In vitro research shows that triptolide, a constituent of thunder god vine, inhibits CYP3A4 enzymes in human microsomes. 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 gist for Selinexor (Xpovio). Your body relies on a liver enzyme called CYP3A4 to help clear this medicine. In lab dish studies, a compound in Thunder God Vine called triptolide appeared to slow that enzyme down. If that held true in people, Selinexor could clear more slowly and build up, which might mean stronger effects and more of its typical side effects, like nausea, vomiting, poor appetite, fatigue, low sodium, and dropping blood counts.

I want to be honest about the evidence though: this is theoretical and has not actually been reported in humans. Still, Selinexor is a serious cancer drug, so don't add Thunder God Vine without first checking with your oncologist or pharmacist.

About Selinexor

What Is Selinexor Used For?

Brand name: Xpovio

Xpovio (selinexor) is used to treat multiple myeloma in adults. When used together with bortezomib and dexamethasone, it is for adults who have had at least one prior treatment. This combination is sometimes called XVd.

Xpovio is also used with dexamethasone alone (called Xd) for adults with relapsed or refractory multiple myeloma — meaning the cancer came back or stopped responding — who have already tried at least four prior therapies and whose disease no longer responds to several other standard drug types.
