Approved drug

In the United States, the FDA approves drugs. Before a drug can be prescribed, it must undergo the FDA's approval process. While a drug can feasibly be used off-label (for non-approved indications), it still is required to be approved for a specific disease or medical condition.[2] Drug companies seeking to sell a drug in the United States must first test it. The company then sends the Food and Drug Administration's Center for Drug Evaluation and Research (CDER)[3] evidence from these tests to prove the drug is safe and effective for its intended use. A fee is required to make such FDA submission. For financial year 2020, this fee was: for an application requiring clinical data ($2,942,965) and for an application not requiring clinical data ($1,471,483).[4] A team of CDER physicians, statisticians, chemists, pharmacologists, and other scientists reviews the company's data and proposed labeling. If this independent and unbiased review establishes that a drug's health benefits outweigh its known risks, the drug is approved for sale. The center doesn't actually test drugs itself, although it does conduct limited research in the areas of drug quality, safety, and effectiveness standards.

As of the end of 2013, the FDA and its predecessors had approved 1,452 drugs, though not all are still available, and some have been withdrawn for safety reasons.[5] Accounting for subsequent corporate acquisitions, these approvals were earned by approximately 100 different organizations.[5]

In the European Union, it is the European Medicines Agency (EMA) that evaluates medicinal products.

In Japan, the agency regulating medicinal products is Pharmaceuticals and Medical Devices Agency (PMDA).
