The pharmacokinetics and bioavailability of mebendazole in man: a pilot study using [3H]‐mebendazole.

Abstract
Following the intravenous administration of a tracer dose (1.7 microgram) of [3H]-mebendazole to a man, an elimination half-life of 1.16 h was observed and the volume of distribution was calculated to be 2.03 l/kg. After oral administration of the same dose, an elimination half-life of 0.74 h was observed. The bioavailability of mebendazole from the solution was found to be 17%.
