Regulation of the Arterial Blood Pressure

  • A. Philippu
Part of the Handbook of Experimental Pharmacology book series (HEP, volume 54 / 1)


In recent years impressive work has been carried out concerning the central sites of action of antihypertensive drugs; together with physiologic and histochemical approaches, this work has led to exploration of centres and pathways of the brain involved in the regulation of the arterial blood pressure. The aim of this chapter is to outline recent concepts concerning the importance of catecholamine systems in cardiovascular control. For this purpose attention will on the one hand be focused on experimental hypertension and on the putative role of adrenaline-containing neurones of the brain for blood pressure control and on the other hand on the possible involvement of catecholamine systems in the aetiology of hypertension.
