Comparative Hemolytic Activity of Mephenesin, Guaiacol Glycerol Ether and Methocarbamol in vitro and in vivo.

Abstract
Mephenesin, guaiacol glyceryl ether (GG) and methocarbamol (AHR-85) have been compared as to their relative hemolytic activity in vitro and in vivo. Evidence is presented that GG and AHR-85 may be administered slowly as saturated aqueous solutions in large doses with little danger of an appreciable degree of hemolysis as indicated by the serum bilirubin and hemochromogen tests.
