Biosimilar Regulations: Current Framework and Future Prospects.

Introduction/objective: Biosimilars, a class of biologic medications that are highly similar to reference biologics, have emerged as cost-effective alternatives to their expensive originator counterparts. Due to their complex nature and manufacturing processes, biosimilars differ significantly from small molecule generics and must undergo a rigorous assessment to ensure safety, efficacy, and accessibility. This review explores the regulatory landscape surrounding biosimilars across key markets such as the United States, Europe, and India, with a focus on approval processes and post-marketing pharmacovigilance for patient safety.
