Medications Acting on the RAAS System Flashcards
ACE Inhibitors (ACEI) end in?
-pril
ACEI MOA
Reduce levels of angiotensin II and increase levels of bradykinin
ACEI Therapeutic Uses
HTN
HF
MI
Diabetes
Nephropathy
Prophylaxis of cardiac patients
Decreasing Angiotensin II does what with ACEI?
Vasodilation, decrease blood volume, potassium retention, decrease cardiac and vascular remodeling
Increasing Bradykinin does what with ACEI?
Cause vasodilation, increase coughing, and potentially (yet rarely) cause angioedema
ACEI Side Effects
HYPOTENSION (first dose)
Hyperkalemia
Cough
Angioedema
Fetal Injury
ACEI Drug Interactions
Diuretics
ANY Antihypertensive Agent
Drugs that INCREASE POTASSIUM
Lithium
NSAIDS
ARBs MOA
Blocks access of angiotensin II causing dialation of arterioles and veins, reducing excretion of potassium, aldosterone, increasing renal excretion of water and sodium
DOES NOT INHIBIT KINASE II (NO BRADYKININ) = NO COUGH
ARBs end in?
-sartan
Therapeutic use of ARBs
HTN
HF
Diabetic nephropathy (can prevent too)
Patients that cannot tolerates ACEI
ARBs Side Effects
Angioedema
Renal Failure
Fetal Injury
NO cough r/t NO BRADKININ INCREASE
Direct Renin Inhibitors MOA
Completely block renin release decreasing the cleavage of angiotensinogen to angiotensin I
Direct Renin Blockers end in?
-ren
Direct Renin Inhibitor Side Effects
Angioedema
Cough
GI effects
Hyperkalemia
Fetal Injury and death
Aldosterone Antagonists MOA
selective blockade of aldosterone receptors decreasing effects
