Introduction
Regulatory documentation refers to the structured preparation, compilation, submission, and maintenance of scientific and legal documents required to obtain and maintain approval for pharmaceutical products. It forms the foundation of Regulatory Affairs and ensures that medicines comply with regulatory standards for safety, efficacy, and quality established by authorities such as the U.S. Food and Drug Administration, the European Medicines Agency, and the Central Drugs Standard Control Organization.
Regulatory documentation spans the entire product lifecycle, beginning with early research and continuing through clinical development, marketing authorization, and post-marketing surveillance. It supports product approvals, renewals, variations, and ongoing regulatory compliance.
