Pharmacokinetics of single and multiple doses of flusoxolol (Ro 31-1411) in healthy subjects.
Flusoxolol (Ro 31-1411) is the pharmacologically active optical isomer of Ro 31-1118, a potent cardioselective beta-adrenoceptor antagonist with partial agonist activity. It was given to 6 healthy volunteers in a single dose, 40 mg, and then in multiple doses, 40 mg daily for 8 days. Plasma concentration data were best described by a linear two-compartment pharmacokinetic model with first order absorption, and the results confirmed linear kinetics. Pharmacokinetic data for flusoxolol were comparable to those for the racemate Ro 31-1118.
