What class of medication is ReoPro?

1. Thrombin inhibitor

2. Platelet inhibitor

3. Vasodilator

4. Aldosterone antagonist

The correct answer is: Platelet inhibitor

ReoPro, also known by its generic name abciximab, is classified as a platelet inhibitor. It works by inhibiting the glycoprotein IIb/IIIa receptor on the surface of platelets, preventing them from aggregating or clumping together, which is crucial in the process of blood clot formation. This mechanism is particularly beneficial in patients undergoing certain cardiovascular procedures, such as percutaneous coronary interventions, as it helps reduce the risk of thrombus formation during and after these procedures. In the context of the other options, thrombin inhibitors specifically target the enzyme thrombin to prevent clot formation, which is a distinct mechanism from that of ReoPro. Vasodilators, on the other hand, work by relaxing blood vessel walls to lower blood pressure and increase blood flow, while aldosterone antagonists are used to block the effects of aldosterone in the kidneys, impacting fluid and electrolyte balance. None of these classifications align with the action of ReoPro, making the designation as a platelet inhibitor the accurate choice.
