Zomepirac Sodium (Zomax) is a pyrrole-acetic acid structurally related to tolmetin sodium. Zomepirac is a prostaglandin synthetase inhibitor and is not an opioid, an opioid antagonist, or a salicylate. Zomepirac was approved by the Food and Drug Administration for marketing in the United States as an analgesic. It was indicated for all forms of mild to moderately severe pain, and was being promoted as a "comprehensive, non-addicting analgesic." Later Zomepirac was found to be associated with fatal and near-fatal anaphylactoid reactions. The manufacturer voluntarily removed Zomax tablets from the Canadian, US, and UK markets in March 1983.

Sample Use Guides

In Vivo Use Guide

The oral dose of zomepirac for mild to moderately severe pain is 50-100 mg every four to six hours. In acute moderate to severe pain in adults, a 100-mg dose would be reasonable initial therapy. In chronic pain situations, the 50-mg dose may be as effective in some patients as the 100-mg dose. Doses of more than 100 mg are not recommended.

Route of Administration: Oral

In Vitro Use Guide

Zomepirac failed to displace tritiated etorphine significantly at concentrations up to 200 umol/l. It was active (3-7 X 10(-5) mol/l) on both the electrically stimulated guinea pig ileum and mouse vas deferens but was less efficacious than morphine; these effects were not reversed by narcotic antagonists.
