Biosimilar Medicines
Main Article Content
Abstract
Biosimilars/biosimilar medicines have been developing rapidly, promising to bring many benefits in the diagnosis, treatment, prevention of diseases, and human health improvement. Biosimilar is a medicine that is highly similar to an already licensed biological product (reference medicine). Although there are some minor differences in the inactive ingredients, there are no clinically significant differences in the purity, potency, and safety between the two products. The development of biosimilars is a challenging multistep process. Unlike "generic" medicine, the development of biosimilars requires comprehensive studies to demonstrate comparability to the reference medicine and to ensure safety and efficacy. Therefore, there are many unique characteristics in the research and development, biological activity testing, approval, and quality control of biosimilars.
This review discusses the characteristics of biosimilar medicines and the challenges in their research, development, and approval.
