A randomized, double-blind clinical trial in 50 patients was done to compare the efficacy and tolerance of single doses of intramuscular diclofenac 75 mg and dipyrone 2 g in acute renal colic. Both drugs were equally effective, but diclofenac was better in terms of complete relief of pain. Vital signs were affected according to the stress and pain.
