Sorrel and Clinafloxacin

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

Moderate

ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP)

Why this applies to Clinafloxacin

Clinafloxacin falls under ORGANIC ANION-TRANSPORTING POLYPEPTIDE SUBSTRATES (OATP) — the group Sorrel interacts with.

Sorrel might reduce the effectiveness of OATP substrates by reducing their absorption from the gut.
In vitro research shows that sorrel inhibits OATP1A2. Theoretically it may inhibit other OATPs. The OATPs are expressed in the small intestine and liver and transport drugs into cells. Inhibition of OATP may reduce the bioavailability of oral drugs that are substrates of OATP.
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: Clinafloxacin is an antibiotic from the fluoroquinolone family, and your body relies on special gut transporters (called OATPs) to help shuttle it from your intestines into your bloodstream. Lab research suggests sorrel can block one of these transporters, OATP1A2, and possibly others. In theory, that could mean a little less of the antibiotic gets absorbed, which matters because an antibiotic needs to reach high enough levels to fully clear an infection.

I want to be straight with you, though: this is based only on test-tube findings, not real patients, so we don't truly know if it happens in people. Everyday culinary amounts of sorrel are far less concerning than concentrated supplements. To be safe, separate them by a couple of hours and check with your pharmacist or doctor before mixing them.

From our pharmacist’s overview on the Clinafloxacin page

“If you have been prescribed clinafloxacin, a quinolone antibiotic, start with the four interactions rated major, because they all do the same thing: apple, grapefruit, and orange juice, along with activated charcoal, can sharply cut how much of the drug you absorb, and an antibiotic that never reaches your bloodstream cannot clear the…”
