What is difference between biosimilar and generic?
Generic drugs are chemically identical to the original branded drug and, as such, cost significantly less because they don't require much testing. Because biosimilars are made from living organisms, though, and don't contain identical ingredients to their name-brand counterparts, they still require some testing.
What is the difference between a biologic and a biosimilar?
