Funny Nomenqlature
Well, the use of the phonetically naked, lone Q (without a following 'e') in 'Leqembi" is apparently not so unique in drug trade names. Here are some others, which like the new Biogen drug look to be awkwardly contrived and artificial:
CIBINQO
Qbrexza
Qelbree
Qinlock
QNASL
Qsymia
Qtern
Qvar
There are many others, too, with interior lone q's. Pharmaceutical marketing is strange; qwestionable, even.
