Single dose pharmacokinetics and absolute bioavailability of mirabegron, a ?3-adrenoceptor agonist for treatment of overactive bladder

Abstract

Mirabegron pharmacokinetics were linear after i.v. dosing (7.5 - 50 mg), but increased more than proportionally after oral dosing (25 - 150 mg) as a result of increased F. Sex differences in exposure could be explained by body weight and for oral dosing, also by F. Mirabegron was in general well tolerated up to the highest doses studied, 50 mg i.v. and 150 mg oral.
