African Wild Potato and Diclofenac epolamine

These two interact in 3 distinct ways. Each one is explained separately below.

Why Are There 3 Interactions?

African Wild Potato interacts with whole categories of medication. Diclofenac epolamine falls into 3 of those categories, so it can interact with African Wild Potato in 3 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES

1 of 3

Why this applies to Diclofenac epolamine

Diclofenac epolamine falls under ORGANIC ANION TRANSPORTER 3 (OAT3) SUBSTRATES — the group African Wild Potato interacts with.

In vitro evidence shows that African wild potato extract inhibits OAT3. This drug transport protein is involved in renal tubular uptake of some drugs from the blood and then elimination in the urine. Inhibition of this transporter decreases renal elimination and increases drug levels in the body. The clinical significance of this in humans is not known.
Some substrates of OAT3 include cephalosporins, famotidine (Pepcid), furosemide (Lasix), hydrochlorothiazide (HCTZ), methotrexate, NSAIDs, probenecid, ranitidine (Zantac).
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 explains PharmD, Clinical Pharmacist

Here's the gist with the Flector or Licart patch (diclofenac epolamine). In a lab dish, African Wild Potato blocked a kidney transporter called OAT3 that helps clear certain drugs out through your urine. Diclofenac is one of those drugs. So in theory, if that transporter is slowed down, diclofenac could leave your body a bit more slowly and build up slightly. That might mean more of the usual NSAID side effects, like stomach upset, heartburn, fluid retention, raised blood pressure, or stress on the kidneys.

I want to be honest about how shaky this is. This is only test-tube evidence, and we don't know if it actually matters in people. A skin patch also puts less into your bloodstream than a pill. Still, please run it by your pharmacist or doctor first.

ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES

2 of 3

Diclofenac epolamine also falls under ORGANIC ANION TRANSPORTER 1 (OAT1) SUBSTRATES.

In vitro research shows that African wild potato extract inhibits OAT1. This drug transport protein is involved in renal tubular uptake of some drugs from the blood and then elimination in the urine. Inhibition of this transporter decreases renal elimination and increases drug levels in the body. The clinical significance of this in humans is not known.
Some substrates of OAT1 include acyclovir (Zovirax), adefovir (Hepsera), cephalosporins, cidofovir (Vistide), cimetidine (Tagamet), ciprofloxacin (Cipro), furosemide (Lasix), hydrochlorothiazide (HCTZ), NSAIDs, oseltamivir (Tamiflu), pravastatin (Pravachol), probenecid, simvastatin (Zocor), and zidovudine (Retrovir).

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for Flector or Licart (diclofenac epolamine). Your kidneys help clear diclofenac out of your body, partly through a transporter called OAT1. In lab studies, African Wild Potato appears to block that transporter. In theory, that could slow how fast you flush the drug out, letting diclofenac build up a bit higher than usual.

If that happened, you might notice more typical diclofenac side effects, like stomach upset, heartburn, fluid retention, or higher blood pressure, and over time more strain on the kidneys. I want to be honest though: this is only test-tube evidence, so we don't know if it actually matters in real people. It's worth a quick chat with your pharmacist before combining them.

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

3 of 3

Diclofenac epolamine also falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES.

In vitro research shows that African wild potato extract inhibits cytochrome P450 2C9 (CYP2C9). However, this effect has yet to be reported in humans. Until more is known, use with caution. Theoretically, concomitant use of African wild potato with CYP2C9 substrates might increase the risk for adverse effects from these substrates. Some of these drugs include nonsteroidal anti-inflammatory drugs (NSAIDs) such as diclofenac (Cataflam, Voltaren), ibuprofen (Motrin), meloxicam (Mobic), and piroxicam (Feldene); celecoxib (Celebrex); amitriptyline (Elavil); warfarin (Coumadin); glipizide (Glucotrol); losartan (Cozaar); and others.
Severity Moderate Likelihood Possible Evidence D

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the basic idea with Flector or Licart (diclofenac epolamine). Your liver uses an enzyme called CYP2C9 to break this NSAID down. In test-tube studies, African Wild Potato appears to slow that same enzyme. If that holds true in people, your body could clear diclofenac a bit more slowly, letting it build up. That can mean more of the typical NSAID side effects, like stomach upset or irritation, a higher chance of bleeding or ulcers, fluid retention, and added strain on the kidneys or blood pressure.

I want to be honest though: this is only laboratory evidence so far, never shown in humans, so it may not amount to much in real life. The patch form also delivers less drug bodywide than swallowed pills. Still, it's worth a quick chat with your pharmacist or doctor before combining the two.

From our pharmacist’s overview on the Diclofenac epolamine page

“Even as a patch, diclofenac epolamine (Flector, Licart) is still an NSAID that reaches the bloodstream, and its 292 supplement interactions call for genuine care, six of them rated major. The bulk of the list, 202 ingredients, thins the blood or slows clotting, which stacks onto an NSAID's built-in bleeding risk.”
