Comprehensive Drug Guide
How Does Nalfon Work?
Nalfon works by inhibiting the enzymes cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), which are involved in the synthesis of prostaglandins—substances that mediate inflammation, pain, and fever. By reducing the production of prostaglandins, fenoprofen alleviates pain and decreases inflammation.
