The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage of diclofenac sodium are reviewed. Diclofenac, the first nonsteroidal anti-inflammatory agent (NSAID) to be approved that is a phenylacetic acid derivative, competes with arachidonic acid for binding to cyclo-oxygenase, resulting in decreased formation of prostaglandins. The drug has both analgesic and antipyretic activities. Diclofenac is efficiently absorbed from the gastrointestinal tract; peak plasma concentrations occur 1.5 to 2.0 hours after ingestion in fasting subjects. Even though diclofenac has a relatively short elimination half-life in plasma (1.5 hours), it persists in synovial fluid. The drug is metabolized in the liver and is eliminated by urinary and biliary excretion. In clinical trials, diclofenac was as effective as aspirin, diflunisal, indomethacin, sulindac, ibuprofen, ketoprofen, and naproxen in improving function and reducing pain in patients with rheumatoid arthritis. For treatment of osteoarthritis, diclofenac was equivalent in efficacy to aspirin, diflunisal, indomethacin, sulindac, ibuprofen, ketoprofen, naproxen, flurbiprofen, mefenamic acid, and piroxicam. Diclofenac was as effective as indomethacin or sulindac in treating ankylosing spondylitis. The most frequent adverse effects reported for diclofenac were gastrointestinal, but these effects were fewer and less serious than occurred with aspirin or indomethacin; in addition, diclofenac caused fewer central nervous system reactions than indomethacin. Diclofenac is administered in divided doses with meals. The recommended total daily dosage is 100 to 150 mg (osteoarthritis and ankylosing spondylitis) or 150 to 200 mg (rheumatoid arthritis). Diclofenac is effective, but no more so than other NSAIDs. It is structurally distinct and offers another choice in the treatment of rheumatological conditions.

Diclofenac sodium is a nonsteroidal antiinflammatory drug (NSAID) that has been used in 120 countries since its introduction in Japan in 1974. It is currently the eighth largest-selling drug and the most frequently used NSAID in the world. Diclofenac, a phenylacetic acid derivative, is a potent inhibitor of cyclooxygenase enzyme activity, and may also interact with the lipoxygenase enzyme pathway, and with the release and reuptake of arachidonic acid. Diclofenac is almost completely absorbed, highly protein-bound, penetrates well into synovial fluid, and is extensively metabolized. Comparative studies have shown that diclofenac is at least equivalent in efficacy to aspirin and other NSAID when used for the treatment of rheumatic diseases such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis. Diclofenac also possesses potent analgesic properties. Clinical trials suggest that diclofenac has a favorable side-effect profile, excellent patient tolerability, and a lower patient dropout rate when compared with aspirin and other NSAID.

Diclofenac sodium, a phenylacetic acid derivative, is a non-steroidal, anti-inflammatory, analgesic agent advocated for use in rheumatoid arthritis, degenerative joint disease, ankylosing spondylitis and allied conditions, and in the treatment of pain resulting from minor surgery, trauma and dysmenorrhoea. Published data indicate that diclofenac 75 to 150mg daily (25 to 50mg 3 times daily) is comparable in efficacy with ordinary aspirin 3 to 5g daily and indomethacin 75 to 150mg daily in rheumatoid arthritis and with indomethacin in osteoarthritis. Available data suggest that in patients with osteoarthritis diclofenac sodium is comparable in efficacy and tolerability with naproxen, ibuprofen, sulindac and diflunisal. As oral diclofenac is generally given in 3 divided daily doses it may be at a disadvantage relative to less frequent administration with naproxen, diflunisal and sulindac in rheumatoid arthritis, although there is some evidence of diclofenac's efficacy when administered twice daily, or once daily as a slow release tablet. The drug is also available as suppositories and ampoules for intramuscular injection. No one of the non-steroidal anti-inflammatory agents is the most suitable drug for all patients requiring such therapy, and diclofenac should be considered along with other drugs of its type in the arthritic patient.

Aceclofenac is a phenylacetic acid derivative with anti-inflammatory and analgesic properties similar to those of diclofenac. However, preclinical studies suggest that the potential of aceclofenac to cause gastrointestinal damage is less than that of diclofenac. Double-blind comparative trials indicate that the efficacy of aceclofenac is at least equivalent to that of ketoprofen and similar to that of indomethacin and diclofenac in patients with rheumatoid arthritis, similar to that of diclofenac and piroxicam in patients with osteoarthritis of the knee and similar to that of tenoxicam, indomethacin and naproxen in patients with ankylosing spondylitis. The analgesic efficacy of aceclofenac 100mg is more prolonged than that of paracetamol (acetaminophen) 650mg. If the apparently improved gastrointestinal tolerability of aceclofenac compared with diclofenac is confirmed by wider clinical experience, aceclofenac will have the potential to become a preferred initial drug in an individualised NSAID regimen in patients with rheumatic disorders.

Aceclofenac, a phenylacetic acid derivative, is a new nonsteroidal anti-inflammatory drug (NSAID). It is indicated in the symptomatic treatment of pain and inflammatory or degenerative arthropathies: osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, abarticular inflammations, posttrauma or postoperative inflammations. The usual oral dosage of aceclofenac is 100 mg twice daily in adults. Its clinical efficacy seems to be similar to that of other NSAIDs, but its safety profile, especially gastro-intestinal tolerance, appears to be better. Finally, in vitro studies suggested that aceclofenac may exert positive effect on cartilage matrix metabolism.
