🔹 Conclusion:
-
Naproxen is generally better for acute pain (like injury, gout, cramps).
-
Aceclofenac is usually preferred for chronic inflammatory conditions (like osteoarthritis) due to lower GI side effects.
-
Safety depends on the individual’s liver, kidney, GI, and cardiac health. Doctor consultation is advised before use.
