In order to compare analgesic treatments effectively one must measure pain over time. In a single-dose clinical analgesic trial one typically obtains repeated pain measurements from each patient during a relatively short period (4-6 hours). Such measurements constitute multivariate data, which are usually reduced by simple addition to a single derived pain(More)
The analgesic efficacy and side-effects of a single parenteral dose of metkephamid acetate 70 mg were compared with those of pethidine (meperidine) hydrochloride 100 mg and placebo in a double-blind, randomised, controlled clinical trial. 30 out of 32 postoperative patients completed the study--10 in the metkephamid group, 11 in the pethidine group, and 9(More)
The residual effects of three hypnotics were investigated by the method of 24-h polygraphy (EEG, EMG, and EOG). The drugs were triazolam 0.25 mg and 0.5 mg, flurazepam 15 mg and 30 mg, nitrazepam 5 mg and 10 mg, and placebo. The subjects were healthy volunteers, eight men and eight women with an average age of 34.3 years. The number of total polygraphic(More)
To test for sustained hypnotic efficacy, triazolam (0.6 mg) or flurazepam (30 mg) was given to chronic insomniac patients for 7 consecutive nights in parallel, double-blind design. Triazolam at this dose was an effective hypnotic by all usual subjective measures and did not produce appreciable hangover. Flurazepam performed similarly. For either drug,(More)
