Ca(cid:374)desarta(cid:374) (cid:862)sarta(cid:374)(cid:863) competes with receptor for angiotensin ii. Thiazides: act on distal tubule (chlorothiazide (diuril )-> 2-3% effect. Loop diuretics (furosemide (lasix )-> 20-25% effect: act on ascending loop of henel. Note: if hypertension due to volume overload, have to see which one to give them. Keep all bp controlled vs just the vasculature. Block n & ne on (cid:1005) receptors on heart. Hr, contractility (sv), conduction velocity bp arrhythmias.
