Randomized Controlled Trial Multicenter StudyComparison of two doses of ketoprofen to treat pain: a double-blind, randomized, noninferiority trial.
The aim of our study was to compare the efficacy and safety of two doses of ketoprofen (200 mg vs. 300 mg/day) in ambulatory emergency patients with pain related to traumatic and nontraumatic bone and joint diseases. We tested the hypothesis that the efficacy of the lower dose was not lower than that of the higher dose in a double-blind, randomized, noninferiority trial. Patients included in the study were aged 18-65 years with closed benign trauma of the motor system or acute noninfectious rheumatologic conditions, with a resting pain intensity ≥3/10 on a numeric pain scale (NPS), requiring ketoprofen for 5 days. ⋯ The mean change in pain intensity at rest (difference between groups: 0.0, 95% CI -0.4 to 0.4; P = 1.00) and in analgesic consumption (difference between groups: -0.6, 95% CI -1.9 to 0.6; P = 0.33) was not significantly different between the two groups, and the differences were lower than the predefined inferiority margins (0.5 and 1.5, respectively), thus demonstrating noninferiority. No significant difference was noted in the incidence of adverse events (21% vs. 20%, P = 0.71). The efficacy of the 200-mg daily dose of ketoprofen in relieving pain in emergency cases was not inferior to that of the 300-mg dose.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialRandomized, comparative, double-blind study of amlodipine vs. nicardipine as a treatment of isolated systolic hypertension in the elderly.
A 90-day, multicenter, randomized, double-blind, parallel-group study was conducted to compare the efficacy of amlodipine (once a day) with nicardipine (two to three times a day), in the treatment of isolated systolic hypertension (ISH) in the elderly. Patients (n = 133) aged > or = 60 years, with ISH were randomized to receive either amlodipine 5 mg/day, or nicardipine 60 mg/day (titrated if necessary to 10 mg/day and 100 mg/day, respectively) for 90 days. Efficacy was assessed by measuring office blood pressure (BP), and 24-h ambulatory blood pressure monitoring (ABPM). ⋯ Both treatments were well-tolerated. The sustained effect of amlodipine, compared with nicardipine, was reflected in its significantly greater antihypertensive activity, particularly during the nocturnal period, as assessed by ABPM. The study demonstrates that once a day dose of amlodipine is an effective antihypertensive treatment for elderly ISH patients.
