title: [Pharmacokinetics of the pressor substance, 5,8-dimethoxy-trans-2-(2-hydroxyethyl)-amino-3-hydroxy-1,2,3,4-tetrahydronaphthalene hydrochloride (1b), after intravenous use].
abstract: The authors investigated the pharmacokinetics of the pressor substance 5,8-dimetoxy-trans-2-/2-hydroxyethyl/-amino-3-hydroxy-1,2,3,4-tetrahydronaphthaline hydrochloride (1b), which possessed strong pressor action. Blood concentrations after venous administration in a dose of 1 mg/kg of body weight were determined by means of exctration spectrofluorometric method. The data complied with the biexponential equation, meeting the requirements of an open two-compartment model. There was a quick elimination of the substance from the central compartment, which correlated also with the data for quick disappearances of the effect on the arterial pressure.
