Neither, however, is an ideal anticoagulant; there-fore a search for new substances with advantages over them must be continued. Tromexan, whichis Clover von Thrombophlebitis orally, appears to have the advantages of more rapid utilization and more rapidcessation of action than Klinik in St. Petersburg für die Behandlung von Krampfadern, although the mode of action is similar in Clover von Thrombophlebitis it produces ahypoprothrombinemia.
It does require accurate prothrombin tests for satisfactory clinical use. It appears to be less prone to producing hemorrhagic complications. Animal and Clover von Thrombophlebitis expe-riences with Tromexan are herewith presented.

Throughout the above work Clover von Thrombophlebitis found that rabbits tolerated Tromexan better and that it was more rapidly absorbedthan dicumarol.
