Just curious, why are drug names such a disaster? Do LLMs not understand pronunciation keys?
And the patients generally don't have a pronunciation key. Doctors prescribing might not, either.
It ends up being quite a lot of variation.
As some examples: Wegovy, Ixempra, Qvar, Keflex
Iunno, pretty sure a car manufacturer will sue me for trademark infringement if I try to manufacture a Beetle under my brand name.
The bigger answer is regulations in some places against the drug name inferring what it treats.
If you want to do global marketing; you gotta go for lowest common denominator: something meaningless in every language/slang.
