title: WY 16225 (dezocine), a new synthetic opiate agonist-antagonist and potent analgesic: comparison with morphine for relief of pain after lower abdominal surgery.
abstract: Dezocine (Wy 16225), a new analgesic was compared randomly and double-blind with morphine 10 mg in 160 female patients complaining of moderate (group I) or severe (group II) pain after elective lower abdominal surgery; both drugs were given i.m. In group I, pain relief with dezocine 10 and 15 mg was significantly greater than dezocine 5 mg; dezocine 10 mg appeared equipotent with morphine 10 mg. Similar, but statistically insignificant differences were observed in group II. Patient sedation was minimal and untoward side-effects infrequent with all doses of the trial drugs.
