[Therapy of orthostatic dysregulation. Comparative studies on anti-hypotensive sympathomimetics with a tilt-table test].

In 7 patients suffering from orthostatic hypotension the early behaviour of arterial mean blood pressure was studied in the tilting table experiment under influence of etilefrine, norfenefrine, gepefrine (D-(+)-1-(3-hydroxyphenyl)-2-aminopropan-(2R, 3R)-hydrogentartrat) and of its I-isomere. Significant improvement of early orthostatic disregulation of the arterial pressure could be only observed under gepefrine. Amelioration seems to be induced by sensitization of the pressoreceptors.
