Understanding Pharmaceutical Regulations
Pharmaceutical products in the United States are among the most heavily regulated products by FDA. The regulatory framework covers everything from drug development and approval to manufacturing, labeling, marketing, and post-market surveillance.
For companies involved in manufacturing, repacking, relabeling, or distributing drug products, compliance starts with establishment registration and drug listing. All drug establishments must register annually with FDA and maintain current drug listing information. Our drug establishment registration guide covers the full process, deadlines, and fees.
The cGMP requirements for drug products (21 CFR Parts 210 and 211) are comprehensive and strictly enforced. FDA conducts regular inspections of pharmaceutical manufacturing facilities, and non-compliance can result in serious consequences including warning letters, consent decrees, product seizures, and criminal prosecution.
Over-the-counter (OTC) drugs have a unique regulatory pathway through the monograph system, which has been modernized by the OTC Monograph Reform Act of 2020. Understanding which pathway applies to your product is essential for compliance. For NDC assignment and labeler code guidance, see our complete NDC number guide.

Drug cGMP Compliance
21 CFR Parts 210 and 211 establish comprehensive cGMP requirements for pharmaceutical manufacturing. These regulations ensure drugs are consistently produced and controlled according to quality standards.
FDA inspects pharmaceutical facilities regularly. Significant violations can result in warning letters, consent decrees, product recalls, and import alerts for foreign manufacturers.
Key cGMP Elements
OTC Drug Monograph System
OTC drugs that conform to applicable monographs can be marketed without individual FDA approval. Common monograph categories include:
Pain Relievers
Examples: Acetaminophen, Ibuprofen, Aspirin
Cough/Cold
Examples: Dextromethorphan, Guaifenesin
Antacids
Examples: Calcium carbonate, Magnesium hydroxide
Topical Antimicrobials

Sunscreens
Examples: Zinc oxide, Titanium dioxide
Skin Protectants
Examples: Petrolatum, Dimethicone
Important Note
Products that do not conform to an applicable OTC monograph require a New Drug Application (NDA) before marketing. This includes products with active ingredients not covered by a monograph, or those that deviate from monograph specifications for dosage, formulation, or labeling.
Frequently Asked Questions
Get answers to common questions about pharmaceutical FDA compliance.
What is drug establishment registration?
All domestic and foreign establishments that manufacture, repack, relabel, or salvage drug products must register with FDA. Registration is done electronically through FDA's Structured Product Labeling (SPL) system using the Drug Registration and Listing System (DRLS). Registration must be renewed annually between October 1 and December 31. Foreign establishments must also designate a US Agent.
What is an NDC number and how do I get one?
The National Drug Code (NDC) is a unique 10-digit, 3-segment identifier for drug products. It identifies the labeler, product, and package. To obtain an NDC, you must first obtain a labeler code from FDA, then assign product and package codes. NDCs are required for all commercially distributed drugs and must be included in drug listing submissions and on product labels.
What are the drug listing requirements?
All commercially marketed drug products must be listed with FDA using the electronic SPL submission system. Initial listing must be submitted within 5 days of beginning commercial distribution. Updates are required in June and December of each year, or within 30 days of certain changes. Listing information includes product composition, labeling, and establishment information.
What is the OTC Drug Monograph system?
The OTC Drug Monograph system provides conditions under which certain OTC drugs are generally recognized as safe and effective (GRASE). If your product conforms to an applicable monograph, it can be marketed without individual FDA approval. The monograph specifies: acceptable active ingredients and doses, labeling requirements, and testing standards. Products not conforming to a monograph require a New Drug Application (NDA).
What cGMP requirements apply to drug manufacturers?
Drug cGMP regulations (21 CFR Parts 210 and 211) require manufacturers to maintain quality systems covering: organization and personnel, buildings and facilities, equipment, production and process controls, laboratory controls, packaging and labeling, holding and distribution, and records. FDA conducts inspections to verify compliance. Non-compliance can result in warning letters, seizures, and injunctions.
Do I need an NDA or ANDA to market a drug?
It depends. Prescription drugs require either a New Drug Application (NDA) for new drugs or an Abbreviated New Drug Application (ANDA) for generics. OTC drugs that conform to applicable monographs can be marketed without individual approval. OTC drugs with new active ingredients or those not covered by a monograph need an NDA. The OTC Monograph Reform Act of 2020 modernized this process.
What labeling requirements apply to drug products?
Drug labeling must comply with 21 CFR Part 201. Requirements include: established name and proprietary name, quantity of contents, name and address of manufacturer/distributor, adequate directions for use, required warnings, active and inactive ingredients, and lot number and expiration date. OTC Drug Facts labeling format is required for over-the-counter drugs. Prescription drugs have additional labeling requirements.
Do foreign drug manufacturers need a US Agent?
Yes, all foreign drug establishments must designate a US Agent when registering with FDA. The US Agent must reside or maintain a place of business in the US and serves as a communication link between FDA and the foreign establishment. The agent must be available during regular business hours to assist FDA with emergency situations and respond to inquiries.
