Palbociclib

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: Palbociclib

Examples of brand names: Ibrance [EU/DE]

ATC code: L01EF01

Main use (for orientation): Breast cancer

Documented research summary

CBD docking with palbociclib as a reference is not an experiment involving combined exposure or clinical evidence for the pair. Missing data do not establish safety.

Uncertainties and limitations

The 28 cannabinoid names in the register define the search scope, not 28 clinically studied pairs. Missing data do not establish safety.

No complete new systematic literature search and no independent medical or pharmaceutical professional approval. Note the dosage form and the country of authorisation of the product information.

Sulfation is not UGT glucuronidation.

Structured assessment

Category: Drug context

Cannabinoid scope: 28 register names within the documented search scope; no newly established direct finding for the target cannabinoid–drug pair. This must not be equated with 28 clinically studied combinations.

Evidence status: Drug properties from regulatory product information; insufficient data for a direct cannabinoid–drug pair finding in the material assessed.

Mechanism / drug context: CYP3A and SULT2A1 metabolism.

Type of supporting material: Targeted product-information review and documented individual literature screening; no newly verified direct cannabinoid–drug pair study.

Clinical interpretation: The clinical relevance of a specific cannabinoid combination has not been determined. Drug context may warrant individual professional review, but neither a blanket warning level nor an assurance of safety.

Context: Sulfation is not UGT glucuronidation.

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

Source role [V2_LABEL_D0389]: Medicine information: properties of the active substance

Statement supported: CYP3A and SULT2A1 metabolism. Product information: drug context, not evidence for a specific cannabinoid pair or proof of safety.

Source: IBRANCE (PALBOCICLIB) TABLET, FILM COATED [U.S. PHARMACEUTICALS] [V2_LABEL_D0389]

Source role [C_SCREEN_41830580]: Screened search result: no established pair evidence

Statement supported: Palbociclib serves as a reference in CBD docking, not a measured combination effect.

Source role [C_PROTOCOL_D0389]: Documented search result

Statement supported: Documented title/abstract search scope for the active substance. The link displays the reproducible search query, not a study or proof that no interaction exists. Search date: 22 October 2026. Further search runs are documented in the research dataset.

Source: Reproducible literature search strategy: Palbociclib [C_PROTOCOL_D0389]

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: The existing individual review, label review and literature screening were read in full; targeted original PK/interaction passages were checked again, but not all product information and search results were newly reviewed in full text. Search findings are limited to the documented V5 search runs. The linked excluded search result was rechecked using its archived abstract or correction metadata record; this does not imply complete new access to the full text.

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.
