Referring to the crucial role of prostaglandins in inflammation and pain sensitization described earlier, NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) like aspirin and ibuprofen play a key role in managing these symptoms. These medications work by inhibiting the enzymes responsible for the production of prostaglandins. Specifically, NSAIDs block both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes.
COX-1 is typically present in small amounts throughout the body and is constantly active, helping to regulate normal cellular functions. On the other hand, COX-2 is not usually found in resting cells but is produced in large quantities during times of inflammation—this is the enzyme's inducible form.
By blocking these enzymes, NSAIDs prevent the formation of prostaglandins including PGI2 (prostacyclin) and PGE2. As discussed, PGE2 plays a significant role in enhancing the inflammatory process and increasing pain sensitivity by affecting nociceptors. Therefore, by inhibiting the synthesis of PGE2, NSAIDs effectively slow down or halt the inflammatory process and reduce the pain and hypersensitivity associated with it. This action helps alleviate the symptoms of inflammation such as swelling, redness, warmth, and the enhanced pain response.
