Just looked on Memory Alpha. Turns out that inaprovaline is indeed the most-used medication in the franchise, being used fourteen times across four series (TNG, DS9, VOY and ENT). Four of those were administered by Dr. Crusher, but actually the EMH has her beat, ordering it six times. That makes sense, since TNG and VOY are definitely the series I’ve watched the most.
But cordrazine is a close second, with thirteen mentions across four series (TOS, TNG, DS9, VOY). The EMH is actually the one who prescribes that one the most, too, using it four times. McCoy used it three times (though one of those was less than intentional), Bashir used it three times, Crusher twice. The weirdest mention of cordrazine (though it wasn’t actually used) was when Neelix suggested Tom Paris use it on a lizard baby. Cordrazine’s derivative, tricordrazine, was used seven times across two series (TNG and Discovery), including by Pulaski, Crusher, and Culber.
Incidentally, Retinax V is only mentioned once, in Wrath of Khan. We never see it used on screen.

We never see it used to maintain the film’s PG rating.
