Those wondering about the mouthful of a name that is "orforglipron" may be interested in the INN (international nonproprietary name) standard for generic drugs. That name is a "generic" or "nonproprietary" name.

Those typically have a "stem" which indicate the mechanism by which the drug works. In this case, it's "-glipron", which you can parse as "glipr" -- GLP-1 receptor -- and "on" -- it's an "agonist", or something that turns "on" the receptor. So "-glipron"s are drugs which agonize, or activate, the GLP-1 receptor. There are other gliprons in trials, including danuglipron (https://en.wikipedia.org/wiki/Danuglipron) from Pfizer, and many others that don't have assigned INNs.

Semaglutide and liraglutide also agonize GLP-1, so why aren't they gliprons? Because chemically they are analogs of the naturally occurring GLP-1 peptide, so they get the -glutide (GLUcagon-like pepTIDE) stem.

I don't know why tirzepatide got that name. It's a peptide, so "-tide" makes sense, but it's actually listed as a "various" exception in the master document of INNs: https://iris.who.int/bitstream/handle/10665/379226/978924009....
