Abbreviated New Drug Applications [ANDA] Law and Legal Definition

An Abbreviated New Drug Application (ANDA) is an application for a U.S. generic drug approval for an existing licensed medication or approved drug. The ANDA is submitted to Food and Drug Administration's Center for Drug Evaluation and Research, Office of Generic Drugs, which provides for the review and ultimate approval of a generic drug product. Once approved, an applicant may manufacture and market the generic drug product to provide a safe, effective, low cost alternative to the American public. It is termed "abbreviated" because they are generally not required to include preclinical (animal) and clinical (human) data to establish safety and effectiveness. However, generic applicants must scientifically demonstrate that their product is a bioequivalent.

The Drug Price Competition and Patent Term Restoration Act of 1984, sets forth the process by which would-be marketers of generic drugs can file Abbreviated New Drug Applications (ANDAs) to seek Food and Drug Administration approval of the generic.
