Returns FDA approval / clearance events: drug approval actions from Drugs@FDA, medical-device 510(k) clearances, and device PMA (premarket approval) decisions

Returns FDA approval / clearance events: drug approval actions from Drugs@FDA, medical-device 510(k) clearances, and device PMA (premarket approval) decisions. Full history (drugs to 1939, 510(k) to 1976, PMA to the 1960s). This is the BULLISH twin of get_product_recalls — the catalyst dataset for biotech and medtech tickers. Use this when the user asks about: new drug approvals for a company or ingredient, priority-review approvals, tentative generic (ANDA) approvals, device clearances by company or product code, PMA supplements, or to pair an approval date with insider trades / 8-K filings / fundamentals. Sources (filter via the source enum): drugsfda — Drugs@FDA submission actions. One record per submission decision (ORIG = original approval, SUPPL = supplemental). decision_code: AP (approved) | TA (tentative approval — generic approved but blocked by patent/exclusivity). review_priority: PRIORITY | STANDARD — PRIORITY reviews are the higher-signal events. application_number prefix tells the product class: NDA (new drug), ANDA (generic), BLA (biologic). 510k — Device premarket notifications. decision_code SESE ('substantially equivalent' — cleared) dominates ~98%. approval_type: Traditional | Special | Abbreviated. pma — Device premarket approvals (Class III, highest-risk devices — implants, life-sustaining). Originals AND supplements (supplement_number, supplement_reason). decision_code: APPR (approved) | OK30 (30-day supplement accepted) dominate. openFDA ships no description text for PMA codes; decision_description mirrors the code. review_priority='EXPEDITED' marks devices under expedited review; 'PRIORITY' marks priority-review drugs. Empty = standard / not flagged. Company matching: applicant is a substring filter on the sponsor / applicant name AS FILED (e.g., 'Pfizer', 'Boston Scientific'). FDA records carry no ticker or CIK — subsidiaries file under their own names, so try the operating-company name, not the holding company. source_url points at the accessdata.fda.gov detail page (approval letters, labels, review documents). Pure-publisher posture: no derived 'approval odds' or price-impact signals.
