[BDSP. Notice produite par INIST-CNRS J9IR0xEB. Diffusion soumise à autorisation]. Background The absorption, distribution, metabolism and elimination of medicines are partly controlled by transporters and enzymes with diurnal variation in expression. Dose timing may be important for maximizing therapeutic and minimizing adverse effects. However, outcome data for such an effect in humans are sparse, and chronotherapeutics is consequently less practised. We examined a large prospective Sri Lankan cohort of patients with acute poisoning to seek evidence of diurnal variation in the probability of survival. Methods In all, 14840 patients admitted to hospital after yellow oleander (Cascabela thevetia) seed or pesticide [organophosphorus (OP), carbamate, paraquat, glyphosate] self-poisoning were investigated for variation in survival according to time of ingestion. Results We found strong evidence that the outcome of oleander poisoning was associated with time of ingestion (P
