title: Abuse potential of zomepirac.
abstract: Zomepirac sodium, a nonsteroidal anti-inflammatory analgesic, was compared to morphine sulfate and placebo in an abuse liability study in a postaddiction population. Morphine (15 and 30 mg), but not zomepirac (400 and 800 mg), induced pupillary constriction and characteristic morphinelike subjective effects. The 800-mg dose of zomepirac was discriminated but was not euphorigenic. This study indicates that zomepirac is not likely to be abused.
