Warfarin belongs to which drug class?

• A. Anticoagulants
• B. Antibiotics
• C. Antihypertensives
• D. Analgesics

Answer: (A)

Warfarin is an anticoagulant. It works by blocking vitamin K recycling in the liver, which lowers the production of clotting factors II, VII, IX, and X (and the proteins C and S). With fewer of these clotting factors, blood takes longer to clot, which helps prevent new clots from forming and stops existing clots from growing. This is different from antibiotics (fights infections), antihypertensives (lower blood pressure), and analgesics (relieve pain). Remember that anticoagulants don’t dissolve existing clots; they prevent further clotting while the body slowly breaks down current clots. Warfarin is used for long-term prevention of stroke in conditions like atrial fibrillation and for preventing DVT/PE.
