Zedoary and Solifenacin succinate

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

Moderate

CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES

Why this applies to Solifenacin succinate

Solifenacin succinate falls under CYTOCHROME P450 3A4 (CYP3A4) SUBSTRATES — the group Zedoary interacts with.

Theoretically, zedoary might increase levels of drugs metabolized by CYP3A4.
In-vitro research shows that a methanol extract of zedoary strongly inhibits the CYP3A4 metabolism of the tyrosine kinase inhibitors lapatinib and sorafenib, and to a lesser extent, gefitinib.
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 Vesicare (solifenacin): your body clears it mainly through a liver enzyme called CYP3A4. Lab studies suggest zedoary may slow that enzyme down. If it does, solifenacin could clear out more slowly and build up in your system, which can mean stronger antimuscarinic side effects like dry mouth, constipation, blurry vision, dizziness, or even a faster heartbeat.

I want to be honest about how shaky this is. This concern comes only from test-tube work, not from people taking the two together, so it's theoretical. A pinch of zedoary as a spice almost certainly won't matter; concentrated extract capsules are where I'd be more cautious. Before adding a zedoary supplement, run it by your pharmacist or doctor first.

About Solifenacin

What Is Solifenacin Used For?

Brand name: Vesicare

Solifenacin tablets (including the brands solifenacin succinate and VESIcare) are approved for adults with overactive bladder — specifically the symptoms of sudden urges to urinate, leaking urine due to those urges (urge urinary incontinence), and needing to urinate very frequently.

VESIcare LS oral suspension is approved for a different use: treating neurogenic detrusor overactivity (NDO) — a bladder control problem caused by nerve damage or a nervous system condition — in children aged 2 years and older. This liquid formulation is dosed by the child's weight.
