Zomepirac: a review of its pharmacological properties and analgesic efficacy.
Zomepirac is an analgesic which is closely related chemically to the nonsteroidal anti-inflammatory agent, tolmetin. In short term studies mainly involving patients with acute pain of moderately severity, zomepirac was at least as effective as usual therapeutic doses of aspirin, codeine alone or with aspirin, phenacetin and caffeine, dextropropoxyphene with paracetamol, or orally administered pentazocine. Additionally, zomepirac may provide analgesia comparable to that with standard doses of intramuscular morphine in patients with acute pain of moderate intensity, but in severe pain states strong analgesics may be more appropriate. Zomepirac has also been studied in patients with chronic orthopaedic pain or osteoarthritic pain for up to several months, without the need for increased doses. It appears to be at least as effective as usual doses of aspirin when used in this way, with a lower incidence of some side effects such as gastrointestinal disturbances and hearing disorders. Preliminary studies suggest that zomepirac may also be effective in patients with chronic cancer pain who have not been previously maintained on strong analgesics, but further experience is needed to clarify its usefulness in this difficult treatment area.
