To compare efficacy and safety of parecoxib and paracetamol for treatment of acute renal colic due to ureteric stones.
A randomized, double blinded, controlled trial included adult patients presented to emergency department with acute renal colic due to ureteric calculi between June 2019 and August 2020. Patients with hypersensitivity to either drug, peptic ulcer, coronary ischemia, peripheral vascular or cerebrovascular disease, hepatic impairment (Child-Pugh score >10) or chronic kidney disease stage 4 or 5 were excluded. Eligible patients were randomized to group 1 who received 1g intravenous Paracetamol infusion or group 2 who received 40mg intravenous Parecoxib infusion. Pain analogue score (PAS) was evaluated before treatment and 30 minutes afterwards. The primary endpoint was the need for rescue analgesia for persistent pain. Safety was evaluated by the incidence of adverse events.
The study included 203 patients (102 in group 1 and 101 in group 2). Pretreatment patients’ data were comparable for both groups. The mean PAS decrease from 7.6 to 3.8 in paracetamol group (P<0.001) and from 7.8 to 3.4 in parecoxib group (P<0.001). Rescue analgesia were needed in 36 patients (35.3%) in paracetamol group and 27 patients (26.7%) in parecoxib group (P=0.187). Minor adverse events developed in two patients (2%) in paracetamol group and three patients (3%) in parecoxib group (P=0.683).
Paracetamol and Parecoxib were effective for treatment for patient with acute renal colic. Both treatments showed comparable results in reduction of pain and need for rescue analgesia with minimal adverse events.
