Input: Eleven studies with 1053 patients (550 on dipyrone) met the inclusion criteria. Unfortunately, few data were available for analysis; most analyses were based on the results of single, small trials and statistical pooling of the results was inappropriate. Efficacy estimates were calculated as the weighted mean percent of patients achieving at least 50% pain relief with the range of values from trials contributing to the analysis. However, these estimates were not robust. Commonly reported adverse effects with intravenous dipyrone were dry mouth and somnolence, and one study reported pain at the injection site. Insufficient information was available for safety analyses. Limited available data indicated that single dose dipyrone was of similar efficacy to other analgesics used in renal colic pain, although intramuscular dipyrone was less effective than diclofenac 75 mg. Combining dipyrone with antispasmolytic agents did not appear to improve its efficacy. Intravenous dipyrone was more effective than intramuscular dipyrone. Dry mouth and somnolence were commonly reported with intravenous dipyrone. None of the studies reported agranulocytosis.
Output:

This review aimed to assess the effectiveness and safety of single dose dipyrone in adults with moderate/severe renal colic pain but there were too few data to obtain clear results. The data available indicated that intravenous dipyrone was more effective than intramuscular dipyrone, and combining dipyrone with antispasmolytic agents did not improve its efficacy. Commonly reported side effects included dry mouth and drowsiness, and some patients experienced pain at the injection site. Agranulocytosis was not reported.
