The effects of 4-hydroxyantipyrine (4-OH), a major metabolite of antipyrine, and its 4-O-sulfate (4-S) on the pharmacokinetics of antipyrine were investigated in rats. Plasma elimination of intravenously administered antipyrine was significantly decelerated under a steady-state concentration of 4-OH but not under that of 4-S. Tissue-to-plasma concentration ratio (Kp) of antipyrine under its steady-state concentration was significantly increased in the brain and heart by the concomitant use of 4-OH, while similar use of 4-S had no effect. The enhancement of the blood-brain barrier (BBB) permeability of antipyrine caused by the concomitant use of 4-OH was believed to be concerned with the increase of the Kp value of antipyrine in the brain. These results suggested that 4-OH could be used as a biodistribution promoter.
