The pharmacokinetics and metabolism of sucralose in the rabbit

The excretion and metabolism of 14C-sucralose has been investigated in non-pregnant and pregnant rabbits after administration of single 10 mg/kg oral doses. Means of 22% and 55% of the dose were excreted in urine and faeces, respectively, by non-pregnant animals during 5 days. Excretion was similar in pregnant animals with means of 22% and 65% of the dose in urine and faeces, respectively, during the same time. Following a single oral dose, a mean of approximately 7% of the dose was still being excreted during the 96–120-hr collection period. Only one major radioactive component was detected in urine samples which corresponded to unchanged sucralose.
