Study snapshot

DesignDouble-blind randomized factorial trial
ModelHuman
Sample222 randomized; 217 assessable at 2 hours
InterventionStandard 20.25-hour IV NAC versus modified 12-hour regimen, with or without ondansetron
Duration12-20.25 hours
EndpointsVomiting/retching; Anaphylactoid reactions; Treatment interruption; ALT rise

What the study showed, in plain terms

Key trial testing whether a shorter, modified IV NAC regimen reduces treatment toxicity in paracetamol poisoning.

Key findings

The modified 12-hour protocol substantially reduced vomiting and severe anaphylactoid reactions, but the trial was not powered to prove noninferior antidote efficacy.

What this study can and cannot tell us

Hospital overdose regimen; cannot be extrapolated to oral supplement dosing.
