Ketamine Pharmacokinetics

[VomitGreen]

So Im looking for pharmacokinetics of ketamine i.m. I found some stuff, but not as much as I was hoping for a 2 page essay. I know that the absorption is about 4 minutes, and that it is 93% bioavailable. Also the it is excreted 90% from urine. But when it gets into the blood stream where does it go, obviously to the brain, but after that, straight to the liver, ? So if you can help please do.
I need a bit more info on all parts, absorption, distribution, metabolism and excretion.
Thanks
