Pharmacokinetics of 14C-ambazone in rats

Abstract

In rats, the pharmacokinetics of 14C-ambazone after i.v. and oral administration was studied. The results demonstrate that the compound is incompletely absorbed from the gastrointestinal tract, penetrates rapidly and to a high degree into various tissues and is preferentially eliminated via the kidneys. After i.v. administration of 50 mg/kg b.m. disposition half-life in whole blood is about 6-7 h. The extent of absorption from the gastrointestinal tract is about 40%.
