T45: Poisoning by primarily systemic and haematological agents, not elsewhere classified

T45.7: Poisoning: Anticoagulant antagonists, vitamin K and other coagulants

A drug can cause poisoning if, for example, too much of it is taken. The drug may also be administered or taken by mistake.

Platelets and various clotting proteins in the blood are involved in blood clotting. The platelets can adhere to one another in such a way that they stop a bleed. The clotting proteins stabilize the platelets that have stuck together. This enables wounds to heal, for example.

These drugs can be used, among other things, for conditions where the blood does not clot sufficiently. Coagulation-promoting agents can cause blood clots to form. Blood clots can block blood vessels.
