How much profit is there to be made on a drug with an expired patent?

It was discovered in Germany in 1934 (a Nazi drug!!!

) and approved for use in the US in 1944. The patents may have expired before I was born,

!

And what may add to DU-Folks Hate-Trump misery, another older anti-parasite drug may enter testing soon, Ivermectin.

Reality is Reich-Wing!!!
