Abstract
Chlorothiazide decreases plasma volume, heart size, and cardiac output. The oligemia stimulates vasomotor tone; this tends to maintain arterial pressure because chronic arterial hypertension is characteristically self-sustaining and homeostatic. This oligemic stimulation of vasomotor tone results in increased sensitivity to the antihypertensive effect of drugs depressing or blocking vasomotor function.Keywords
