Generic pharmaceutical makers have become a formidable segment of the pharmaceutical market. According to the Center for Justice and Democracy at New York Law School, 80% of all drugs prescribed are generic, and generic drugs are chosen 94% of the time when they're available.

Brand-name drug patents typically last about 20 years, and when those patents are up, the ingredients become available to generic manufacturers who then can introduce their own versions of those drugs to the marketplace. Insurance companies traditionally have steered patients toward generic options by offering lower co-pays compared to brand-name drugs.

Some Background on Generics

According to the U.S. Food and Drug Administration, generic drugs have the same active ingredients, work the same way, and provide the same clinical benefits as their brand-name counterparts.

This does not mean that generic drugs are 100% equivalent to their brand-name counterparts. What it does mean is that their manufacturers must demonstrate to the FDA that they can be effective substitutes for the drugs they're copying.

This list represents some of the top generic drug manufacturers of 2018.
