anti-angina Flashcards
Nitroglycerin / Nitrostat
Nitrate vasodilator
for: All forms of angina. Acute releif or prophylaxis before physical activity.
MOA:Nitric oxide –> immediate vasodilation of arteries –> more blood blow to the heart. Pre load is reduced due to reduced peripheral venous tone.
SE: Headache. Hypotension. Orthostatic hypotension. Rebound tachycardia. Tolerance (with transdermal administration).
Concurrent use of Silendafil (Viagra) is containdicated due to risk of severe hypotension.”
Isosorbide Dinitrate / Isordil
Long acting nitrate vasodilator
for: Angina. Prophylaxis of angina.
MOA: Similar to nitroglycerin.
SE:Headache. Hypotension. Orthostatic hypotension. Rebound tachycardia.
Concurrent use of viagra is containdicated due to risk of severe hypotension.
Propanolol / Inderal
also for HTN–Non-Selective Beta Blocker
for:Angina. Post-MI. HTN. Panic attacks. Migraine headaches. Decrease infarct size in patients with acute MI.
MOA:Blocks adrenergic stimulation –> decreases heart rate, decreases oxygen demand, decreases renin release.
SE:”Hypotension. Bradycardia. Fatigue. Impotence. Bronchoconstriction.
Can cause rebound hypertension and tachycardia.”
Atenolol / Tenormin
Selective (Cardiospecific) Beta Blocker
for: Angina, HTN, MI. Decrease infarct size in patients with acute MI.
MOA: B1 adrenergic blockage –> decreases heart rate and myocardial oxygen demand
SE: Hypotension. Bradycardia. Fatigue. Impotence. (Less risk of bronchoconstriction than with Propanolol.)
Amlodopine / Norvasc
Ca channel blocker
for: Angina, particularly vasospastic angina. Hypertension.
MOA: Blocks Ca influx into cells –> vasodilation of cardiac and peripheral arteries –> less sympathetic-induced coronary artery spasm
SE: Flushing. Headache. Hypotension.
Morphine Sulfate
Analgesic
for:”Pain relief in unstable angina or MI. Anxiolytic
MOA:Opiate receptor agonist –> potent reduction of pain and anxiety –> decreased sympathetic tone –> mild peripheral vasodilation –> mild preload reduction
SE: Respiratory depression. Severe Hypotension.
