Efficacy and tolerability of intramuscular and oral meloxicam in patients with acute lumbago: a comparison with intramuscular and oral piroxicam.
In this controlled, randomised, parallel-group, multicentre study, the efficacy and tolerability of an intramuscular (i.m.) dose of meloxicam (15 mg) on Day 1 followed by seven days of oral meloxicam (15 mg/day) were compared with those of an i.m. dose of piroxicam (20 mg) on Day 1 followed by seven days of oral piroxicam (20 mg/day) therapy in a total of 169 outpatients with acute lumbago. Time to onset of analgesic action after i.m. injection was determined, and overall efficacy, pain on movement, limitation of daily activities, local tolerability at the injection site and overall tolerability were assessed by investigators and patients on verbal rating scales (VRSs). Adverse events and laboratory assessments were documented. Meloxicam and piroxicam showed a rapid onset of action after i.m. injection (40 and 45 minutes median time, respectively), overall efficacy of both therapies was highly rated, and limitations to daily life were greatly reduced in the majority of patients in both groups. There were no statistically significant differences in efficacy between meloxicam and piroxicam. Local and overall tolerabilities were equally good for the two drugs, but there were fewer gastrointestinal (GI) adverse events among meloxicam patients (1.2% of patients) than piroxicam patients (7.0% of patients). The improved tolerability profile of meloxicam may be explained by its selectivity towards cyclooxygenase-2.
