FDA Regulations

FDA Regulations are the body of federal rules the U.S. Food and Drug Administration issues and enforces to protect public health across food, drugs, biologics, medical devices, cosmetics, and tobacco. Rooted in the 1906 Pure Food and Drugs Act and expanded through the Federal Food, Drug, and Cosmetic Act, most of them are codified in Title 21 of the Code of Federal Regulations (21 CFR). They set the terms for how regulated products are developed, tested, manufactured, labeled, and tracked before and after they reach the market.

• 21 CFR - The core codification, spanning everything from food additives to drug approval and device classification.
• 21 CFR Part 11 - The rule governing electronic records and electronic signatures, which is where software, APIs, and audit trails come directly into scope.
• Quality System Regulation - Manufacturing and design controls (21 CFR Part 820) that medical-device makers must demonstrate.
• Unique Device Identification - The UDI system and its GUDID database that give devices machine-readable identity for traceability.
• Postmarket surveillance - Adverse-event and recall reporting obligations that keep regulated products accountable after launch.

In real API operations, FDA Regulations shape how healthcare, pharma, and medical-device companies design and govern their systems: Part 11 turns electronic records, e-signatures, and audit trails into hard API requirements, and UDI/GUDID expectations push structured, machine-readable product identity into the data an API exposes. For providers in these sectors, regulatory posture is part of the API contract — validation, access controls, and immutable audit logging are not optional features but compliance obligations. As agents begin to read and act on regulated healthcare data through standards like FHIR, the ability to prove that an API meets FDA recordkeeping and traceability rules becomes a core trust signal.
