Question: 1 / 400

What is the mechanism of action for thrombolytic drugs?

They prevent the formation of clots

They increase the production of red blood cells

They convert plasminogen to plasmin to break down thrombi

Thrombolytic drugs work by converting plasminogen to plasmin, which is an enzyme that helps break down blood clots. This option is the correct explanation because the other options do not accurately describe the mechanism of action for thrombolytic drugs. Option A refers to antiplatelet drugs that prevent the formation of clots by inhibiting platelet aggregation. Option B refers to erythropoietin, a hormone that stimulates the production of red blood cells. Option D is an incorrect statement as thrombolytic drugs directly affect and break down clots, thus affecting blood flow.
