Center for Drug Evaluation and Research (CDER)

The Center for Drug Evaluation and Research (CDER) is the FDA division that evaluates and regulates prescription and over-the-counter drugs, including most small-molecule and many biologic medicines. It reviews clinical evidence for safety and effectiveness before approving drugs for the U.S. market.

What is the Center for Drug Evaluation and Research (CDER)?

The Center for Drug Evaluation and Research (CDER) is the branch of the U.S. Food and Drug Administration (FDA) responsible for overseeing the medicines Americans take. Its scope covers prescription and over-the-counter drugs, generic products, and a large share of therapeutic biologics, ranging from common small-molecule pills to many injectable treatments.

Before a drug reaches the market, CDER reviewers examine the clinical trial data submitted by manufacturers to judge whether the product is safe and effective for its intended use. The center also continues to monitor drugs after approval, evaluating new safety signals, labeling changes, and manufacturing quality.

Why does CDER matter in healthcare?

CDER decisions determine which therapies clinicians can prescribe and which products enter the supply chain, so the center effectively sets the boundaries of available drug treatment in the United States. Its approvals, recalls, and safety warnings ripple through formularies, pharmacy operations, and prescribing patterns across every care setting.

For surgery centers and infusion practices, CDER-regulated products such as anesthetics, antibiotics, and injectable medications are central to daily operations. Knowing a drug's approval status and labeled indications also affects how those drugs are coded, billed, and justified for reimbursement.
