Drugs in pregnancy. Anticoagulants.
Pregnancy is a period of heightened coagulability and enhanced risk for thrombotic complications. Thromboembolism is the leading cause of maternal mortality. Anticoagulants are very useful during pregnancy for the acute treatment of venous thromboembolism and for the prevention of recurrent venous thromboembolism. They may also be beneficial in patients with thrombophilias, particularly among women who have experienced adverse pregnancy outcomes such as recurrent pregnancy loss. Anticoagulation is essential but problematic in the management of pregnant women with mechanical heart valve prostheses. When utilizing these medications among pregnant women the potential benefits must be balanced against the possibility of maternal haemorrhagic complications, adverse effects on the pregnancy or toxic effects on the fetus. This chapter summarizes current knowledge about the anticoagulant agents, their potential toxicities and their therapeutic role in pregnant women with various indications for anticoagulant therapy.
