What class does Warfarin sodium (Coumadin) belong to?

Anticoagulant
Antiplatelet
Analgesic
Antipyretic

The correct answer is: Anticoagulant

Warfarin sodium (Coumadin) belongs to the class of drugs known as anticoagulants, which help prevent blood clots from forming. This class is different from antiplatelet drugs, like aspirin, which help prevent blood clots from getting bigger. Analgesics and antipyretics, on the other hand, are types of pain relievers and fever reducers, respectively, and do not have the same function as Warfarin sodium. They are not used to prevent blood clots. Therefore, A, anticoagulant, is the correct and most appropriate answer for this question.
