cardiovascular response to stress ( jet air ) , baroreceptor sensitivity ( bradycardia to phenylephrine ) and central catecholamine synthesis rates ( accumulation of 5-hydroxytryptophan and dihydroxyphenylalanine after synthesis inhibition ) were unchanged supporting earlier evidence that central mechanisms probably do not contribute to the hypotensive effects of ketanserin .
