How each medicine works

Ibuprofen — Has analgesic, antipyretic and anti-inflammatory effects. The selected label says the mechanism is not fully understood and may involve inhibition of prostaglandin synthesis.
Meloxicam — Inhibits cyclooxygenase (COX-1 and COX-2) and prostaglandin synthesis; analgesic, anti-inflammatory and antipyretic.
Aspirin — Aspirin inhibits prostaglandin synthesis and platelet aggregation through cyclooxygenase acetylation; its irreversible platelet COX-1 inhibition reduces thromboxane A2 formation.
Naproxen — Has analgesic, anti-inflammatory and antipyretic effects. The mechanism is not completely understood but involves COX-1 and COX-2 inhibition; reduced prostaglandin production may contribute.
Celecoxib — Has analgesic, anti-inflammatory and antipyretic effects; its mechanism is believed to involve reduced prostaglandin synthesis, primarily through COX-2 inhibition.
Diclofenac — Has analgesic, anti-inflammatory and antipyretic effects. The mechanism is incompletely understood but involves COX-1/COX-2 inhibition and reduced prostaglandin synthesis.
Diclofenac — The mechanism is not completely understood but involves inhibition of COX-1 and COX-2. Diclofenac inhibits prostaglandin synthesis in vitro; reduced peripheral prostaglandins may contribute to its analgesic and anti-inflammatory effects.
Ketorolac — NSAID analgesic with an incompletely understood mechanism that may involve prostaglandin-synthetase inhibition.
Ketorolac — Nonsteroidal anti-inflammatory drug thought to act by inhibiting prostaglandin biosynthesis.
Indomethacin — Mechanism is incompletely understood but involves COX-1 and COX-2 inhibition; reduced prostaglandin synthesis may contribute to its peripheral effects.
Nabumetone — Prodrug converted in the liver to 6MNA, a potent inhibitor of prostaglandin synthesis.
Etodolac — Shows anti-inflammatory, analgesic and antipyretic activity in animal models. Its mechanism is not completely understood and may involve prostaglandin-synthetase inhibition.
