-rzaa?

[edit]

I came here hoping to learn the etymology of the very unusual suffix -rzaa in risankizumab-rzaa. Could someone please add an explanation?

According to https://www.accessdata.fda.gov/drugsatfda_docs/nda/2019/761105Orig1s000NameR.pdf, it is "devoid of meaning." Why add those extra five characters, -rzaa, if they are devoid of meaning? (talk) 15:21, 23 July 2024 (UTC)[reply]
