The pharmacological control of musculoskeletal pain.

The modern therapy of the pain of inflammatory rheumatic disease and osteoarthritis is based on several advances in molecular biology, which are reviewed in this paper. Inhibition of the ubiquitous enzyme cyclooxygenase by the nonsteroidal anti-inflammatory drugs including the salicylates prevents the production of endoperoxides, which are pro-inflammatory, and prostaglandins E2 and I2, which sensitize peripheral pain receptors. In addition, a fundamental understanding of neural tracts that inhibit the pain signal has introduced the concept of giving low dose tricyclic antidepressants for chronic pain to block the re-uptake of serotonin from the neural cleft of synapses. This amplifies the effect of serotonin and catecholamines, which are neurotransmitters for these inhibitory tracts.

Ibuprofen.

Ibuprofen was introduced in England in 1967 and in the United States in 1974 as an anti-inflammatory drug in humans. It has weak but definite anti-inflammatory properties similar to those of aspirin, milligram for milligram, but with considerably less adverse effect on the stomach. Ibuprofen is chemically related to fenoprofen and naproxen, but lack of effect for any one in this chemical class of propionic-acid derivatives does not necessarily mean lack of effect for any other in an individual patient. The drug has analgesic properties, probably related to its anti-inflammatory effect. It inhibits prostaglandin synthesis and has no effect on the adrenopituitary axis, making it a nonsteroidal agent. Ibuprofen has been shown to be effective in rheumatoid arthritis and osteoarthritis and is probably effective in ankylosing spondylitis, gout, and Bartter's syndrome.

Estimates of doses of antiinflammatory drugs in man by testing for analgesic potency. I. 1-isopropyl-4 phenyl-7-methyl-2 (1H) quinazolone versus aspirin.

Dosage estimates of antiinflammatory drugs in human arthritis Phase II trials are difficult to obtain and prolong such trials unnecessarily. Antiinflammatory drugs almost always have analgesic properties in man and good dose estimates for analgesic activity can be obtained. In 140 patients with surgical pain, 300, 600, and 1200 mg of aspirin were compared to 75, 150, and 300 mg of 43-715 (1-isopropyl-4-phenyl-7-methyl-2 (1H) quinazolone), an antiinflammatory quinazolone derivative, for analgesia in a double-blind trial using subjective response methodology. The test drug was shown to be analgesic at a level four times more potent, milligram for milligram, than aspirin, an estimate that should be useful for later definitive Phase II trials in arthritis.
