What are Generic Drugs and How Do They Work?

The Basics of Generic Drugs

A generic drug is a medication that is equivalent to a brand-name product in dose, strength, quality, and intended use, but does not carry the brand name. It is usually less expensive than the brand-name version.

The active ingredient in a generic drug is identical to the active ingredient in the brand-name drug, and it is intended to have the same therapeutic effect. However, the inactive ingredients (such as fillers, binders, and colorings) may be different.

Examples of generic drugs include:
» Amoxicillin (generic version of Amoxil)
» Metformin (generic version of Glucophage)
» Atorvastatin (generic version of Lipitor)
» Montelukast (generic version of Singulair)
» Lisinopril (generic version of Prinivil or Zestril)

It is important to note that generic drugs are subject to the same standards of quality, safety, and efficacy as brand-name drugs. In the United States, generic drugs must be approved by the Food and Drug Administration (FDA) before they can be sold to the public.
