Cardiac/Vascular/analgesics Flashcards
blockes ACE from converting angiotensin 1 to angiotensin 2 leading to decrease in BP. Decrease in aldosterone production and increase in serum K levels with NA+ and fluid loss DO NOT USE WITH ARB; treatment of hypertension, HF, diabetic nephropathy, and left ventricular dysfunction after an MI (ACE inhibitor)
MOA of Captopril
hypertension, HF, diabetic nephropathy, left ventricular dysfunction after MI
Indications of Captopril
tachycardia, MI, rash, pruritus, gastric irritation, aphthous ulcers, peptic ulcers, dysgeusia, proteinuria, bone marrow suppression, cough
Adverse effects of Captopril
treatment for hypertension, diabetic nephropathy with elevated serum creatinine and proteinuria with pts with type 2 diabetes and hypertension (ARB)
MOA of Losartan
hypertension, diabetic nephropathy with elevated serum creatinine and proteinuria pts with type 2 diabetes and hyper tension
Indications of Losartan
dizziness, headache, diarrhea, abdominal pain. URI, cough, back pain, fever, muscle weakness, hypotension
Adverse effects of Losartan
inhibits movement of calcium ions across membrane of cardiac and arterial muscle cells, depressing impulse and leaving slowed conduction, decreased MI contractibility and dilation of arteries which lowers BO and decrease myocardial oxygen consumption; treatment for hypertension in extended release form; DO NOT CRUSH
MOA of Diltiazem
essential hypertension in extended release form
Indications of Diltiazem
dizziness, light headedness, headache, peripheral edema, bradycardia, atrioventricular block, flushing, nausea
Adverse effects of Diltiazem
acts directly on vascular smooth muscle to cause vasodilation and drop in BP, does not inhibit CV reflexes and tachycardia, renin release will occur; vasodilatior
MOA of Nitroprusside
severe hypertension, maintenance of controlled hypertension during anesthesia, acute HF
Indications of Nitroprusside
apprehension, headache, retrosternal pressure, palpitations, cyanide toxicity, diaphoresis, nausea, vomiting, abdominal pain, irritation at injection site
Adverse effects of Nitroprusside
increase intracellular calcium, and allows more calcium to enter myocardial cell during depolarization, causing positive inotropic effect (increase in contraction), increase renal perfusion with diuretic effect and decrease renin release (negative chromotropic- slower HR) and slow conduction through AV node; cardiotonic agent
MOA of Digoxin
HF, atrial fibrillation
Indications of Digoxin
headache, weakness, drowsiness, visual disturbances, arrhythmias, GI upset
Adverse effects of Digoxin
blocks enzyme phosphodiesterase, which leads to an increase in myocardial cell cAMP, increase calcium levels in the cell, causing stronger contractions and prolonged response to sympathetic stimulation, directly relaxes vascular smooth muscle; phosphodiesterase inhibitor
MOA milrinone
short term treatment for HF in patients who do not respond to digitalis, diuretics or vasodilators
Indications for Milrinone
arrythmias, hypotension, nausea, coming, thrombocytopenia, pericarditis, pleuritis, fever, chest pain, burning at injection site
Adverse effects of Milrinone
competitively blocks beta-adrenergic receptors in the heart and kidney, has a membrane stabilizing effect and decreased influence on sympathetic nervous system
MOA of Propranolol
cardia arrhythmias, SVT, ventricular tachycardia induces by digitalis or catecholamines
indications of Propranolol
