> The problem with [the plan of changing the formulas of drugs so they can be re-patented, from the patent-holder's perspective] is that a reformulation doesn’t stop the old drug’s patent from expiring, opening the market for cheap generics. To head this threat off, McKinsey developed a disinformation campaign to discourage doctors from prescribing generics and to convince patients to refuse such prescriptions. The McKinsey campaign included outright lies — false statements claiming that the old formulations were unsafe. Alongside those lies, McKinsey developed messaging to convince patients and docs that the old drugs were “a step backwards.”"<p>Great explanation of Merck disclaiming Ivermectin (see <a href="https://www.merck.com/news/merck-statement-on-ivermectin-use-during-the-covid-19-pandemic/" rel="nofollow">https://www.merck.com/news/merck-statement-on-ivermectin-use...</a> ) despite the drug being safer than Tylenol when used by humans ( <a href="https://www.thedesertreview.com/opinion/columnists/the-great-ivermectin-deworming-hoax/article_19b8f2a6-0f29-11ec-94c1-4725bf4978c6.html" rel="nofollow">https://www.thedesertreview.com/opinion/columnists/the-great...</a> )<p>Edit: They specifically called out "A concerning lack of safety data in the majority of studies" and spread FUD saying "Ivermectin should not be used during pregnancy since safety in pregnancy has not been established."
