There's three main ways the kidneys get rid of drugs. First one is through the filtration. You can breast milk it out, lactate it out or cry it out. And then if they make it all the way to the end of the tubules, you pee it out. Two of the first and then a centredrink every hour. In Australia, at least. That's working off the zero kinetics. Yeah. So that's metabolism. Moving on to excretion, the final phase. Excretion is obviously just getting rid of the drug. Getting it out of the body. There's a couple of different ways. We're going to focus on kidney.
