**Question 120:**
A 65-year-old man with diabetes is admitted to the Coronary Care Unit with a diagnosis of acute ST elevation anterior myocardial infarction. He developed massive hematemesis following streptokinase infusion. Which of the following drugs would reverse the action of streptokinase?
**Options:**
A. Factor VIII concentrate
B. Aminocaproic acid
C. Protamine
D. Vitamin K
E. Fresh frozen plasma
**Correct Answer:**
**B. Aminocaproic acid**
**Explanation:**
Streptokinase is a thrombolytic agent that can cause bleeding complications, including massive hemorrhage such as hematemesis. Aminocaproic acid is an antifibrinolytic agent that inhibits fibrinolysis by blocking the binding of plasminogen to fibrin, thereby reducing the breakdown of clots. This makes it the most appropriate agent for reversing the effects of streptokinase in this case .
