Why does taking non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen reduce fever in a patient with a viral infection?

A)Increased hypothalamic blood flow occurs
B)Elevated viral replication is directly suppressed
C)Peripheral vasodilation enhances heat dissipation
D)Prostaglandin synthesis is effectively inhibited

💡 Explanation

NSAIDs reduce fever because they inhibit cyclooxygenase (COX) enzymes, which are crucial for prostaglandin synthesis; therefore, the hypothalamic set point returns to normal, rather than NSAIDs affecting viral replication directly or causing vasodilation unrelated to prostaglandin activity.
