Regulatory

Approvals (17)

Each record names the authority, jurisdiction, indication text and status. A drug approved in one jurisdiction for one indication is not 'approved' in general.

health-canada-dpdRegulatory17 approval records from 3 sources (hover a row badge for its dataset) · authority, jurisdiction and indication text as published.

Health Canada records are DIN-level: one row per marketed product (brand, strength, form). The Drug Product Database does not publish indications, so no cancer is stated for these rows, and a cancelled or dormant DIN is the status of that one product — not a withdrawal of the molecule.
