Interchangeable Biosimilars

Interchangeable biosimilars are highly similar versions of original biologic medicines that have been thoroughly tested to show they produce the same medical effect and have comparable safety and effectiveness. When labeled as "interchangeable," they can be substituted for the original biologic by pharmacists without needing additional approval from the prescribing doctor, similar to generic drugs for small-molecule medicines. This designation helps increase access to treatments, potentially lowering costs, while maintaining assurance of quality and efficacy.
