Pharmacokinetics and pharmacodynamics of conventional and controlled-release formulations of metipranolol in man

The pharmacokinetics and β-adrenoceptor blocking effects of conventional and sustained-release metipranolol have been studied in 6 healthy male volunteers given a single oral dose of 40 mg. Plasma drug concentrations determined by TLC and a radioreceptor assay, and the inhibition of exercise-induced tachycardia, were monitored for 48 h.
