Etoglucid is a cytotoxic drug used as neoplastic agent for the treatment of malignant tumors. Etoglucid was synthesized by reacting a diol with two equivalents of an alkyl chloride. This alkylating agent is commonly used in Europe but is not available in the United States. It is readily diffusible into the cerebral fluid into cerebrospinal fluid but has a metabolic half-life of only 10 to 15 min. It has been shown in animal experiments to be rapidly destroyed in the liver and thus possibly less damaging to the bone-marrow. Only the polymorphonuclear leucocytes being greatly reduced. The blood returned to normal in two to three weeks, and no other important toxic changes were observed.
