Nifedipine in the treatment of renal colic.
A double-blind randomized, clinical trial was conducted in 43 patients to evaluate the efficacy of sublingual nifedipine in the treatment of pain in renal colic. Comparison was made with a combination of dipyrone, pitofenone and fenpipramide, which is usually administered intravenously in Spain. With nifedipine, pain completely disappeared in 44% of the cases, and with the combination of drugs, in 89% (p less than 0.005). More adverse effects were noted with the combination than with nifedipine. Both treatments brought about a slight drop in arterial pressure without leading to hypotension in any case. There was no change in heart rate. The possible causes of the relatively low level of success with nifedipine were analyzed. The possibility of using nifedipine under certain circumstances in which other drugs are contraindicated or when their administration is unfeasible is suggested.
