What you Should Know About Generic Drugs
By Amanda Covey, Pharm.D.
The Food and Drug Administration (FDA) cites that 7 out of 10 prescriptions dispensed in the United States are filled with generic drugs. But do you really know what a generic drug is?
Let’s begin with the origin of a generic drug. A generic drug starts as a brand name drug. A brand name drug is the first version of the medication that a drug company develops. The drug company spends a great deal of money and time on research and development of the new drug to make sure the drug is safe and effective for human use. The drug company then presents their research to the FDA for approval of the new drug. At this time, the FDA grants a patent for the drug, but the drug is not yet released to the public. After thorough evaluation by the FDA, the drug will then be approved and released onto the market. Patents on drugs last 20 years from the date they are issued, meaning that the company that developed the new drug is the only company that can manufacture and sell the drug for the length of the patent. This is the reason that not all brand name drugs have generics available. A good example is a class of drugs that lower cholesterol called “statins.” Lipitor® is a well-known brand name “statin” that does not yet have a generic because of its original patent protection.
