Theoretically, of course, such an option is possible (as well as many other more exotic ones). But modern medicine does not work with assumptions. She only works with evidence. That is, in order to use a drug for any purpose, it must undergo a serious study (randomized placebo-controlled, etc.), and preferably several, but there are no such studies for these drugs. And if pharmaceutical companies consider (for some reason) beneath their dignity to conduct such research, then, alas, we will not be able to say anything about their effectiveness and, accordingly, the possibility of their application.
Teretically, it is certainly possible ... but unlikely. The argument about money is quite funny - preclinics, for example, are not that expensive, yes. But it is not there either.
And so the evidence base is sales, prestige, and the exit (at least under a patent) into the world ... no one will cut such a chicken
