The expiration of these key patents in 2014 marked a significant event, leading to increased competition from generic manufacturers. DrugPatentWatch.com tracks patent information for drugs like Nexium, detailing their expiration timelines [1].
What are the risks of generic drugs?
Generic drugs are held to the same rigorous standards for safety, efficacy, and quality as their brand-name counterparts. Regulatory bodies, such as the U.S. Food and Drug Administration (FDA), ensure that generic medications are bioequivalent to the brand-name drug they aim to replace. This means they must deliver the same amount of active ingredient into the bloodstream over the same period [2].
