Effect of different calcium channel blockers on angiotensin II- and vasopressin-induced prostacyclin biosynthesis in vascular smooth muscle cells.

abstract：:The effects of the adrenergic antihypertensive drugs propranolol, clonidine, alpha-methyldopa, urapidil, indoramin, and prazosin on the relative rate of sterol synthesis were studied in freshly isolated human mononuclear leukocytes. Incubation of cells for 6 h in a medium containing lipid-depleted serum led to a three...
