Heparin is a powerful anticoagulant medication widely used in medicine, with studies showing its anti-thrombotic activity is primarily mediated by potentiating the natural inhibitor, antithrombin. By doing so, it effectively inhibits the intrinsic and common pathways of the coagulation cascade.

Heparin, a fast-acting anticoagulant, is widely used to prevent and treat blood clots. Unlike the oral anticoagulant warfarin, it does not require monitoring via the International Normalized Ratio (INR), leading many to question: Does heparin affect PT or PTT? The answer lies in its specific mechanism of action within the body's complex coagulation cascade.
