Aceclofenac is a monocarboxylic acid that is the carboxymethyl ester of diclofenac. A nonsteroidal antiinflammatory drug related to diclofenac, it is used in the management of osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis.
Aceclofenac is an oral non-steroidal anti-inflammatory drug (NSAID) with marked antiinflammatory and analgesic properties used to treat osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. Aceclofenac potently inhibits the cyclo oxygenase enzyme (COX) that is involved in the synthesis of prostaglandins, which are inflammatory mediators that cause pain, swelling, inflammation, and fever. Aceclofenac belongs to BCS Class II as it possesses poor aqueous solubility. It displays high permeability to penetrate into synovial joints where in patients with osteoarthritis and related conditions, the loss of articular cartilage in the area causes joint pain, tenderness, stiffness, crepitus, and local inflammation.
