In the context of toxicology, PCCs are primarily used to reverse the effects of anticoagulants like warfarin. When patients on anticoagulants present with bleeding or require urgent surgery, PCCs can rapidly restore the balance of clotting factors, thus stabilizing the patient. The mechanism involves providing an immediate source of clotting factors that have been inhibited by the anticoagulant, thereby allowing the coagulation cascade to proceed.
