Oxaprozin, aspirin, naproxen, and piroxicam have comparable efficacy in osteoarthritis. In a comparative single-blind trial 17 of 10 anti-inflammatory drugs the greatest pain relief in rheumatoid arthritis was achieved by diclofenac, indomethacin, naproxen and tolfenamic acid. The least effective drugs were ketoprofen and proquazone. Diclofenac (Arthrotec, Cambia, others): 70 mg per day is no more effective than a placebo. However, it becomes more effective than a placebo at 150 mg per day. However, it becomes more effective Diclofenac is a potent inhibitor of prostaglandin synthesis in vitro. Diclofenac concentrations reached during therapy have produced in vivo effects. Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in inducing pain in animal models. Prostaglandins are mediators of inflammation. Nonsteroidal anti-inflammatory drugs (NSAIDs) are effective for treating inflammation and various types of painful conditions. Some are available over the counter (OTC), while others require a prescription. Common OTC NSAIDs include ibuprofen (Advil, Motrin) and naproxen (Aleve). Meloxicam (Mobic), diclofenac (Voltaren, Cambia), and celecoxib Many people who have osteoarthritis or rheumatoid arthritis regularly take non-steroidal anti-inflammatory drugs (NSAIDs) in order to reduce pain or inflammation in the joints. Commonly used NSAIDs include acetylsalicylic acid (the drug in medicines like Aspirin), ibuprofen, diclofenac and naproxen. Diclofenac was found to be more effective than Ibuprofen for arthritic pain alleviation in a meta-analysis published in the Journal of Arthritis Research and Therapy. The researchers looked at data from 176 trials that included 146,524 participants. Diclofenac was also found to have a decreased risk of stomach-related side effects than Ibuprofen. Many researchers have also chosen long-term administration of NSAIDs or high doses that is against the intended human therapies. For example, Leonelli et al. compared the effect of 30 mg/kg/day of Ibuprofen and 8 mg/kg/day of rofecoxib on the union potential of a closed femoral fracture in a rat model . Their results showed nonunions in 64.7% They may contain ingredients similar to diclofenac (such as aspirin, ibuprofen, ketoprofen, or naproxen).
