Thunder God Vine and Maraviroc

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Maraviroc

Maraviroc 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 with Selzentry (maraviroc) and Thunder God Vine. Your body relies on an enzyme called CYP3A4 to break down maraviroc and keep its blood levels in a steady range. Thunder God Vine contains a compound (triptolide) that, in lab studies, appears to slow that same enzyme down. If that held true in people, maraviroc could build up a bit and you might notice more of its usual side effects, like dizziness, headache, stomach upset, or feeling unusually tired.

I want to be honest about the strength of this, though. It's only a theoretical concern based on test-tube research, and it has not actually been reported in real patients. Still, since HIV therapy is too important to gamble with, please loop in your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Maraviroc page

“Someone taking maraviroc (Selzentry) for HIV needs a steady blood level to keep the virus suppressed, and that level is exactly what most of the 168 supplements on this page can disturb, so this list calls for genuine care. About 121 entries share maraviroc's clearance route, the CYP3A4 enzyme, which means grapefruit can push levels up…”

About Maraviroc

What Is Maraviroc Used For?

Brand names: Celsentri, Selzentry

Maraviroc treats a specific type of HIV-1 infection called CCR5-tropic HIV-1. It is always used alongside other antiretroviral (anti-HIV) medicines — never alone. A special test called a tropism assay must be done before starting treatment to confirm you have the right type of HIV.

Selzentry (the brand-name oral solution and tablet) is approved for adults and pediatric patients weighing at least 2 kg. Generic maraviroc tablets are approved for adults and pediatric patients aged 2 years and older weighing at least 10 kg. Neither form is recommended for patients whose HIV is classified as dual/mixed-tropic or CXCR4-tropic.
