Daclatasvir

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: Daclatasvir

Examples of brand names: Daklinza [EU; historical example]

ATC code: J05AP07

Main use (for orientation): Hepatitis C

Documented research summary

No verified cannabinoid–daclatasvir finding; enzyme/transporter information is mechanistic context only. 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.

Archived EMA Daklinza information; authorisation no longer valid. No claim of current German availability.

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: Substrate of CYP3A4, P-gp and OCT1; inhibition of several transporters.

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Context: Archived EMA Daklinza information; authorisation no longer valid. No claim of current German availability.

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

Source role [VE_LABEL_D0333]: Medicine information: properties of the active substance

Statement supported: Substrate of CYP3A4, P-gp and OCT1; inhibition of several transporters. Product information: drug context, not evidence for a specific cannabinoid pair or proof of safety.

Source role [C_PROTOCOL_D0333]: 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: 23 October 2026. Further search runs are documented in the research dataset.

Source: Reproducible literature search strategy: Daclatasvir [C_PROTOCOL_D0333]

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.

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.
