Generic Drugs


To help you decode the numerous acronyms and other industry terminology, we've assembled the following glossary.

  • ANDA - Abbreviated New Drug Application
  • API - Active Pharmaceutical Ingredient
  • cGMP - Current Good Manufacturing Practices
  • CPSIA - The Poison Prevention Packaging Act (PPPA) of 1970 established the requirement to use child resistant closures on containers of household chemicals including drugs, and that manufacturers test the closures' effectiveness. The Consumer Product Safety Improvement Act (CPSIA) of 2008 requires that retailers provide certification that products they sell meet the test requirements of the PPPA.
  • DEA - U.S. Drug Enforcement Agency
  • DESI - Drug Efficacy Study Implementation
    These are drugs that were approved solely on the basis of their safety prior to 1962. Thereafter, Congress required drugs to be shown to be effective as well. FDA initiated a Drug Efficacy Study Implementation(DESI) to evaluate the effectiveness of those drugs that had been previously approved on safety grounds alone. These drugs, and those identical, related, and similar to them, may continue to be marketed until the administrative proceedings evaluating their effectiveness have been concluded, at which point continued marketing is only permitted if an NDA is approved for such drugs.

  • FTF - Federal Transition Framework
  • GMP - Good Manufacturing Practice

U.S. FDA Good Manufacturing Practice requirements set forth in the Quality System (QS) regulation are promulgated under section 520 of the Food, Drug and Cosmetic (FD&C) Act.

  • Para. IV - Patent Certification Under the Drug Price Competition and Patent Term Restoration Act, or the Hatch-Waxman Act, a company can seek approval from FDA to market a generic drug before the expiration of a patent relating to the brand name drug upon which the generic is based. The first company to submit an Abbreviated New Drug Application (ANDA) with the FDA has the exclusive right to market the generic drug for 180 days. To begin the FDA approval process, the generic applicant must: 1) certify in its ANDA that the patent in question is invalid or is not infringed by the generic product (known as "paragraph IV certification"); and 2) notify the patent holder of the submission of the ANDA.
