FDA drug approval history from Drugs@FDA — the official record of FDA-approved drug applications. Give a drug name (brand or generic), an FDA application number (e.g. NDA021436), or a sponsor name, and get back each application with its products (brand name, active ingredients + strengths, dosage form, route, marketing status, therapeutic-equivalence code, reference-drug flag) and its full submission history (original approvals, supplements, status + status date, review priority). Free, public-domain US government data. The authoritative "is this drug FDA-approved, by whom, when, and in what formulations" record — point-in-time public records, not medical advice.
