Biosimilars

interchangeable Biosimilar

An interchangeable biosimilar product may be substituted without the intervention of the health care professional who prescribed the reference product, much like how generic drugs are routinely substituted for brand name drugs. This is commonly called pharmacy-level substitution and is subject to state pharmacy laws. The FDA has approved 2 interchangeable biosimilars—biosimilars that pharmacists could substitute interchangeably with reference drugs—since July 2021, but manufacturer-developers are seeking interchangeable status for about 7 other biosimilars, according to Jeff Casberg, MS, RPh, vice president of Clinical Development .
