Etodolac in the management of pain: a clinical review of a multipurpose analgesic.

Etodolac is a non-steroidal anti-inflammatory drug with analgesic properties. Its primary anti-inflammatory mechanism of action is through a selective effect on cyclo-oxygenase-2 (COX-2). It is rapidly absorbed after oral administration, and maximum plasma concentration (C(max)) is reached in 1-2 h, with an elimination half-life (t1/2 ) of 6-8 h.Etodolac has been widely applied in the treatment of inflammatory arthritides such as rheumatoid arthritis, ankylosing spondylitis and gout and in osteoarthritis and has been shown to be efficacious and well tolerated.However, etodolac has other applications which rely primarily on its efficacy as an analgesic. In particular, etodolac has been evaluated in the treatment of a variety of different pain states. Etodolac has been observed to be efficacious in the treatment of acute pain following dental extraction, orthopaedic and urological surgery, and episiotomy, as well as in the treatment of pain due to acute sports injuries, primary dysmenorrhoea, tendonitis, bursitis, periarthritis, radiculalgia and low back pain.These studies indicate that etodolac is a multipurpose analgesic with many clinical applications in addition to its use in the treatment of inflammatory and degenerative forms of arthritis.
