4.2 Absorption, Distribution and Excretion

10 mg/kg (14)C-pentaerythrite, administered orally to 12 mice (females), was absorbed and excreted rapidly. Half of the administered dose left the gastrointestinal tract within 15 min and 68% of the dose appeared in the urine and feces after 4 hr. The compound detected was pentaerythrite.

In ... experiments with (14)carbon pentaerythritol, 69% of (14)carbon was excreted, probably as unchanged compound, in 24 hr urine and 23% in feces /after oral administration to dogs/. Blood levels were greatest after 1 hr.

Feeding studies in human volunteers revealed that about 85% of pentaerythritol fed was eliminated unchanged in urine. Elimination was essentially complete in 30 hr.
