When Ab­b­Vie’s block­buster rheuma­toid arthri­tis drug fi­nal­ly sees some com­pe­ti­tion in the US in 2023, there’s like­ly to be a split field, with some biosim­i­lars, and some in­ter­change­able biosim­i­lars. The added des­ig­na­tion al­lows phar­ma­cists to switch the ref­er­ence prod­uct for the in­ter­change­able with­out a pre­scriber’s con­sent.
