Scientific names should not be allowed to be trademarked. That should include names that are close enough to it that it could be litigated if it were a trade mark.
Actually, someone synthesized something very similar in 1897 and named it "epinephrine". 4 years later, someone independently synthesized it and trademarked it as "adrenaline".
The terminology is now one of the few differences between the INN and BAN systems of names.[72] Although European health professionals and scientists preferentially use the term "adrenaline", the converse is true among American health professionals and scientists. Nevertheless, even among the latter, receptors for this substance are called "adrenergic receptors" or "adrenoceptors", and pharmaceuticals that mimic its effects are often called "adrenergics". The history of adrenaline and epinephrine is reviewed by Rao.[73]
Seems like a couple people were working on this around the same time.
Extracts of the adrenal gland were first obtained by Polish physiologist Napoleon Cybulski in 1895.[94] These extracts, which he called nadnerczyna ("adrenalin"), contained adrenaline and other catecholamines.[95] American ophthalmologist William H. Bates discovered adrenaline's usage for eye surgeries prior to 20 April 1896.[96] In 1897, John Jacob Abel (1857–1938), the father of modern pharmacology, found a natural substance produced by the adrenal glands that he named epinephrine.
Apparently, whoever added this was an awful devil who decided that adding false information with sources that only sourced the history and usage of the term was a good idea.
The trademark is adrenalin, not adrenaline, and owned by Endo, not Pfizer. I have edited the title and am editing the article as we type. Apparently there's someone who posted to the talk page about this back in may but didn't get noticed.
This was changed on 4 May 2023 by someone who thought he was correcting a typo.
I think I just had a glitch in the matrix moment I swear to God I opened this thread and the title said Pfizer, bug after I read your comment I scrolled up and it said Endo International.
