How we grade severity & evidence
Severity levels
- Contraindicated: These should generally not be used together.
- Major: Potentially serious — often needs a change or close monitoring.
- Moderate: Can be significant — usually manageable with monitoring.
- Minor: Usually limited clinical impact.
Evidence grades
- Established: Well documented — supported by controlled studies or strong clinical data.
- Probable: Good supporting evidence, though not definitively proven.
- Suspected: Some evidence suggests this interaction, but it is not well established.
- Possible: Limited or conflicting evidence; the interaction may occur.
- Theoretical: Predicted from the drugs' pharmacology; not yet confirmed in people.
Ratings come from the documented interaction literature and are reviewed by a pharmacist. They describe the documented risk of the combination, not what will necessarily happen to you — your dose, timing, and health picture all matter.
What happens
Increased seladelpar exposure
Interaction Deep Dive
Coadministration of seladelpar and OATP1B1/OATP1B3 and BCRP inhibitors may increase seladelpar exposure. In a drug interaction study in healthy subjects, coadministration of 10 mg seladelpar dose with 600 mg cycloSPORINE (OATP1B1, OATP1B3 and BCRP inhibitor) increased seladelpar AUC and Cmax by 2.1-fold and by 2.9-fold, respectively. If coadministered, closely monitor patients for adverse effects1.
Why it happens (mechanism)
Inhibition of OATP1B1-mediated efflux transport of seladelpar; inhibition of OATP1B3-mediated efflux transport of seladelpar; inhibition of BCRP-mediated efflux transport of seladelpar
