Abstract
SEVERAL coumarin and indanedione drugs are capable of inducing hypoprothrombinæmia, presumably by interfering with the cofactor role of vitamin K in prothrombin synthesis. This role of vitamin K, probably involving electron transport, can be competitively inhibited by coumarins, and the inhibition competitively overcome by large doses of vitamin K (ref. 1).
