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

A report by GlobalData says that Indian generic manufacturers are doing particularly well in the generics marketplace, and more and more companies are moving their manufacturing facilities overseas to cut costs.

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 percent equivalent to their brand-name counterparts, but their manufacturers must demonstrate to the FDA that they can be effective substitutes for the drugs they are copying.

Based on financial numbers provided by Evaluate through 2016, these drug companies are leading the way in the generics marketplace.
