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 FDA'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.
Generic drug applications are termed "abbreviated" because they are generally not required to include preclinical (animal and in vitro) and clinical (human) trial data to establish safety and effectiveness. Instead, generic applicants must scientifically demonstrate that their product is bioequivalent (i.e., performs in the same manner as the innovator drug).
