Randomized Controlled Trial
Treatment of loin pain suspected to be renal colic with papaverine hydrochloride: a prospective double-blind randomised study.
• To assess the efficacy of papaverine hydrochloride combined with a diclofenac sodium suppository to relieve renal colic compared with diclofenac suppository monotherapy, as the effect of phosphodiesterase inhibitors on ureteric muscles might reduce the pain of renal colic. ⋯ • According to our results, i.v. papaverine hydrochloride plus a diclofenac suppository were more effective than the diclofenac suppository alone for treating acute renal colic. • Therefore, i.v. papaverine hydrochloride is a beneficial supplemental therapy to relieve renal colic pain, particularly combined with non-steroidal anti-inflammatory drugs.
