I wanted to get some information about a medication that I heard about. It is known as Freedox, but I am not sure if its common in the U.S. ## Freedox (Tirilazad Mesylate) is an injectable medication. I was unable to gather much information on this drug except locating the active ingredient Tirilazad Mesylate, proposed for use in the treatment of stroke, though results so far have reportedly been mixed.
