Generic Drugs: What You Need to Know When the pain reliever acetaminophen was developed in the 1950s, it was only available under its brand name, Tylenol. Today, acetaminophen can be found in many generic and store-brand versions. Similarly, many drug products, prescription and over-the-counter, have generic versions available. An estimated 44 percent of all prescriptions in the United States are filled with generic drugs. New drugs are developed by innovator firms. Patents protect these companies' investments by giving them the sole right to sell the drug while the patents are in effect. When patents or other periods of exclusive marketing for brand-name drugs are near expiration, manufacturers can apply to the Food and Drug Administration to sell generic versions. The law that allows approval of generic products, the Drug Price Competition and Patent Term Restoration Act of 1984, builds in certain protections for the original drug developer (including patents and marketing exclusivity), but also allows drug sponsors of identical products to apply for FDA approval without repeating the original developer's clinical trials. The law also encourages generic firms to challenge innovator patents by awarding marketing exclusivity to the first generic version challenger. Generic drugs are safe, effective and FDA-approved. According to Gary Buehler, M.D., director of the FDA's Office of Generic Drugs, "People can use them with total confidence."
