Comparison of the onset and intensity of action of intramuscular meloxicam and oral meloxicam in patients with acute sciatica.

In this randomized, double-blind, double-dummy trial, 113 patients with acute sciatica were treated with a single 15-mg dose of meloxicam given intramuscularly (n = 54) or orally (n = 59). There was a significant improvement in induced pain (as measured by using the straight-leg-raising test) in both treatment groups at 60 minutes (P < 0.005), and there was a significant difference in favor of the intramuscular formulation in terms of the time to maximum improvement of induced pain (P = 0.01). Changes in spontaneous pain were similar in both treatment groups and were significant versus baseline (P < 0.01) at 30 minutes after study drug administration. Global efficacy evaluations by both the patients and investigators confirmed that meloxicam 15 mg in an intramuscular or oral formulation was effective in relieving pain in patients with acute sciatica. Meloxicam was generally well tolerated, and the local tolerability of the intramuscular injection was found to be excellent on the basis of both clinical evaluation and assessment of creatine phosphokinase levels.
