Gemfibrozil

For an informed discussion with your doctor or pharmacist. This information collection is not a clinically validated interaction checker. Missing data do not establish safety. Do not change or stop prescribed medicines on the basis of this information. The findings apply to the specific conditions studied; laboratory and animal studies cannot be directly extrapolated to humans.

Active substance: Gemfibrozil

Examples of brand names: Gevilon [DE]

ATC code: C10AB04

Main use (for orientation): Dyslipidaemia

Documented research summary

Within the documented search scope, no sufficiently attributable cannabinoid pair is established for gemfibrozil. The structured assessment distinguishes documented drug context from the absence of specific interaction evidence. Missing data do not establish safety.

Uncertainties and limitations

Do not calculate an exposure change or clinical consequence solely from inhibitor status. Do not independently change prescribed medicines on the basis of this research dataset.

Structured assessment

Category: Drug context

Cannabinoid scope: No specifically substantiated pair involving a registered cannabinoid in the material assessed; no claim that all 28 cannabinoids were comprehensively reviewed simultaneously.

Evidence status: Drug properties supported by product information; insufficient evidence for a specific cannabinoid–drug pair effect.

Mechanism / drug context: Gemfibrozil substantially affects CYP2C8 and OATP1B1; medicines can be affected as a result.

Type of supporting material: Product information and documented individual literature screening; no clinical pair trial approved for use as evidence.

Clinical interpretation: An effect in the other direction, from the medicine to the cannabinoid, is conceivable, but is not supported here by a study of the pair.

Context: Documented interaction mechanism of the medicine, not a measured CBD/THC interaction.

Drug context and gaps in search results are not measured interactions. The source role below describes which statement the source actually supports.

Source role [VD_LABEL_D0240]: Original product information: drug context, not evidence for a cannabinoid–drug pair

Statement supported: Gemfibrozil substantially affects CYP2C8 and OATP1B1; medicines can be affected as a result.

Scope of review: Individual research with documented title/abstract screening and targeted review of original sections. This is not exhaustive evidence that interactions are absent.

Unresolved source question: All individual review fields read. Original product information was rechecked only in the relevant pharmacokinetic/interaction excerpts; no complete recertification of all labels or worldwide full-text search. Literature access was based on the previously documented review; only the listed web sources were additionally read in this round. Do not calculate an exposure change or clinical consequence solely from inhibitor status.

Separately recorded findings

No separately substantiated finding for this drug–cannabinoid pair is recorded within the documented scope of review. This does not prove that no such study exists anywhere or that the combination is safe.
