title: First pass conjugation of phenol following rectal administration in rats.
abstract: The systemic availability of phenol following rectal administration to rats has been compared to intraduodenal and intravenous administration via the hepatic portal and jugular veins. Phenol blood concentration-time curves after the rectal route of dosing indicate that first pass conjugation by the intestinal mucosa and liver is drastically reduced when compared to the other routes of administration.
