Marcumar [3-(l'-phenyl-propyl)-4-hydroxy-coumarin]. A New Anticoagulant

Abstract

Marcumar [3-(1'-phenyl-propyl)-4-hydroxycoumarin] is a new anticoagulant. Marcumar acts more rapidly than Dicumarol, but not quite as rapidly as Tromexan. The action is more prolonged than Dicumarol. As with other anticoagulants, the administration of Marcumar requires conscientious observation and accurate prothrombin complex determinations.
