ANTIHYPERTENSIVE

Cardiac output and Peripheral vascular resistance

Determinants of BP

Baroreceptors

(pressure receptors) specialized cells in the arch of the aorta

Renin- Angiotensin Aldosterone system

Compensatory mechanism when blood pressure within the kidneys fall

Hypertension

“ silent killer” When a person’s blood pressure is above the normal limits for a sustained period

Angiotensin- Converting Enzyme Inhibitors

blocks the conversion of angiotensin I to angiotensin II ; works with the respi. system

captopril and enalapril maleate

Angiotensin- Converting Enzyme Inhibitors (prils) medications

Angiotensin II Receptor Antagonist

Selectively bind the angiotensin II receptors in the blood vessels and adrenal cortex.

telmisartan, losartan, valsartan

Angiotensin II Receptor Antagonist (“sartan”) medications

Calcium Channel Blockers

prevents movement of calcium ions in the myocardium and vascular smooth muscles.

amlodipine, diltiazem, nicardipine

Calcium Channel Blockers MEDICATION

Vasodilators

relaxes smooth muscles of blood vessels esp the arteries; promotes increase blood flow to the brain & kidney

minoxidil, diazoxide, nitroprusside

Vasodilators medications
