title: Acute effects of antagonist of S2-receptors.
abstract: Intravenous administration of ketanserin--a selective antagonist of serotonin receptors--to hypertensive patients resulted in an immediate marked drop of blood pressure accompanied by a decreased excretion of vanilmandelic acid and 5-hydroxy-3-indolylacetic acid. The drug was well tolerated by all patients without any serious complaints.
