Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 presenting with acute renal colic and a pain score of 5 or higher, without major exclusions such as unstable vitals or significant comorbidities.

Probably not a fit

Patients with contraindications to terbutaline or dexamethasone, or those with uncontrolled conditions or recent analgesic use, may not experience benefit.

What this trial studies

This Phase 3 interventional trial compares two active treatments, dexamethasone given intravenously and terbutaline delivered by nebulizer, against placebo for acute renal colic pain in adults presenting to the emergency department. Eligible participants are adults 18–65 with sudden flank pain of at least moderate intensity and no major exclusion criteria such as unstable vital signs or significant comorbidities. Participants are randomized to receive one of the study interventions and are assessed for pain relief and safety outcomes. The study is conducted at a single site, University Hospital Fattouma Bourguiba Monastir, led by the University of Monastir.

Why it matters

Potential benefit: If successful, the treatment could provide faster or greater pain relief for renal colic and offer an effective option in the ED setting.

How similar studies have gone: Prior work has explored beta-agonists or corticosteroids for acute renal colic, but direct head-to-head comparisons in this context are limited, making this trial relatively novel.
