The action of Dicumarol in the human being on plasma prothrombin time and total prothrombin time

American Heart Journal, 1952
Abstract In man, Dicumarol causes an increase in the plasma and in the total prothrombin times. The explanation is offered that Dicumarol reduces both the free and total prothrombin and that a rough ratio between the two forms is maintained. The practical significance of this observation is discussed.
