0.1 mg to 1000 mg as single doses; up to 800 mg twice daily on repeat doses.

Route of Administration: Oral

In Vitro Use Guide

SB223412 antagonized senktide-induced contraction of rabbit isolated iris sphincter muscle (KB = 1.6 nM), and inhibited NK-3 receptorinduced membrane depolarization in guinea-pig bronchial parasympathetic ganglia and substantia nigra pars compacta in guinea pig. SB223412 inhibited senktide-induced miosis in rabbits when given iv (ED50 = 0.44mg/kg) and by 53% when given orally (25 mg/kg, PO).
