Arzneimittelforschung. 1980;30(11):1912-6.

Abstract

(+/-)-1-(Isopropylamino)-3-[p-(2-cyclopropyl-methoxyethyl)-phenoxy]-2-propanol HCl (betaxolol, SL 75212) was given to groups of healthy volunteers, 10 mg daily for 7 days followed by 20 mg daily 7 days in one group, and increasing daily doses up to 60 mg/day for a total of 15 days in the other group. The pharmacokinetics were studied during dosing and in the washout period. The pharmacokinetic characteristics were unchanged after repeated doses, T/2 16-22 h, Vd 7.7-8.8 l/kg; clearance 0.28-0.33 l/h/kg.
