When a drug company develops a new drug, they give it a brand name and obtain a patent for it from the United States government. The patent gives the drug company the exclusive right to make the brand name drug for a certain period of time. This allows the drug manufacturer to earn back the money they invested in developing and testing the drug.
Once the patent expires, other drug companies can apply to the FDA to sell their version of the same drug. These versions are called generic drugs, and they are often less expensive than the original. People trying to save money on their prescriptions may want to consider talking with their doctor to see if the generic version of a drug would be all right for them to use.
All drugs sold in the United States must be approved by the FDA regardless of whether they are brand-name or generic, so consumers can be sure that the drugs they take have been approved by a federal agency. For more information on generic drugs, You can visit the web sites listed below.
