How Does It Work?

It is not entirely known how ketamine works. It is known that the medicine works on certain brain pathways to quickly produce a general state of anesthesia (loss of sensation and awareness) and pain relief. Unlike many other general anesthetics, ketamine maintains respiration (breathing) and a normal or slightly increased muscle tone.
