Here's what I gather from FDA website.
FDA advised pharmaceutical companies recall products containing NDMA from the market April, 2020. Advised, not demanded. Zantac remained on the market until Oct, 2020 when it was discontinued.
Then from the Sandoz pres release: in June, 2021, Sandoz announced released of of 2 new Zantac products, Zantac and Zantac 360, which are normal and extended release versions of famotidine.
So where that leaves that left nut thing, I don't know but you guys can settle up.
