You can see explanations about it.
A generic drug (generic drugs, short: generics) is a drug which is produced and distributed without patent protection. According to the U.S. Food and Drug Administration, generic drugs are identical bioequivalent range to the brand name counterpart with respect to pharmacokinetic and pharmacodynamic properties. By extension, therefore, generics are considered identical in dose, strength, route of administration, safety, efficacy, and intended use. In most cases, generic products are available once the patent protections afforded to the original developer have expired. When generic products become available, the market competition often leads to substantially lower prices for both the original brand name product and the generic forms.
