Legal Definitions - copycat drug

A copycat drug is a type of generic drug that contains the same active ingredient as a brand-name drug, but may have different excipient substances (such as binders or capsules). These drugs are intended for use in the diagnosis, cure, treatment, or prevention of disease.

For example, ibuprofen is a common pain reliever that is sold under various brand names, such as Advil and Motrin. A copycat drug of ibuprofen would contain the same active ingredient, but may have different inactive ingredients.

Copycat drugs are often less expensive than brand-name drugs, but are just as effective. They are regulated by the FDA to ensure that they meet the same standards for safety, quality, and effectiveness as brand-name drugs.
