Background:

Anitrazafen is a topically effective antiinflammatory agent.

Anitrazafen is a topically effective antiinflammatory agent. The disposition of 14C in normal and in bile-duct cannulated rats after oral administration of a single dose of 25 mg/kg of [3-14C]Anitrazafen shows the drug to be well absorbed from the gastro-intestinal tract and biliary excretion to be the major route of elimination of drug and/or metabolites. Plasma concentrations of total 14C after subcutaneous administration of [3-14C]Anitrazafen in corn oil solution are about one half those found after oral administration[1].
