WHO "essential medicine" N-acetylcysteine ("NAC") is the standard treatment for #paracetamol overdose; it replenishes depleted glutathione reserves, which conjugate N-acetyl-p-benzoquinone imine (“NAPQI”), the toxic metabolite. It’s also a mucolytic, decreases the effects of alcohol, and sometimes helps with mental disorders. #drugs #toxicology #medicine

#video by Sal Mercogliano from today about #shipping.

And the #USA is also attacking #oil tankers and container ships in the Strait. But Lloyd’s List says at least 26 “Iranian shadow fleet vessels” have evaded the US blockade.
