A Randomized Controlled Study to Evaluate the Efficacy of Fomepizole in the Treatment of Acetaminophen Overdose
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study is a randomized, placebo-controlled double-blinded clinical trial of patients presenting with acetaminophen poisoning who are at increased risk of developing liver injury. With this trial the investigators are hoping to show the superiority of acetylcysteine (NAC) + fomepizole (4-MP) compared to treatment with acetylcysteine alone. The primary objective of this trial is to determine the effect of fomepizole on the severity of acute liver injury in patients with acetaminophen poisoning.
