drugs Flashcards
Procainamide class and blocks
IA, Na channel blocker (and K blocker)
Procainamide prolongs the ____ _____ and treats ventricular______. It could cause _________.
Action potential
refractory ventricular fibrillation, pulseless ventricular tachycardia
SLE symptoms
Quinidine class and blocks
IA, Na channel blocker (and K blocker)
Quinidine prolongs the _____ _____ by a decrease cardiac _______ . It is used to treat ____arrhythmias, PSVT, and WPW. Side effects cause
prolongs action potential, decreasing cardiac excitability and contractility.
Treats atrial arrhythmias.
Torsades de pointes, cinchonism, thrombocytopenia, anticholinergic
Lidocaine is a class ____ and blocks____
Class IB, blocks Na channels thru fast Na channels
Lidocaine acts through the ____fibers, depresses automaticity. Higher affinity of ______ tissue.
Purkinje fibers
ischemic tissue
Lidocaine could cause
neurotoxicity
Metoprolol class:
reduces:
treats:
Side effects:
II, beta-1 adrenergic receptor blocker
reduces: heart rate and myocardial contraction force (prolongs AV node conduction)
treats: sinus tachycardia, PSVT, A. Fiber/flutter
SE: Av block, cardiac arrest
Amidarone class, blocks:
Amidarone III, blocks Na, K, Ca; blocks beta-1 receptors
Amidarone indications and SE
indications: atrial/vent arrhythmias
SE: torsades de pointes, pulmonary fibrosis
Digoxin class, inhibits/blocks, ions affected
Digoxin misc. class, inhibits/blocks Na/K-ATPase, increased intracellular Na and greater Ca influx
Digoxin SE and indications
indicated for FIRST LINE WITH HEART FAILURE w/ sedation, A. Fib, SVT
SE; nausea, vomiting, mental status change, color changes, EKG changes
Atenolol
decrease blood pressure and renin release and SYM outflow
Lessons angina
causes hypotension/bradycardia
Dilitazem and Nifedepine
Ca channel blocker treats arrythmia
Causes edema, constipation, flushing, dizziness
Sodium Nitroprusside
NO relaxes the arterioles, decreases preload and afterload
for hypertensive emergency, acute MI, aortic dissection, Heart failure,
Causes hypotension, tachycardia, cyanide toxicity
Losartan
decreases ANG II,
for heart failure and diabetic nephropathy
Could cause acute renal failure
Hydrachlorathiazide
decreases sodium absorption
1st LINE HTN TX
Could cause sexual dysfunction, high blood sugars, lipidemia
Fenoldopam
1st LINE FOR ACUTE HTN TX
Could cause flushing, hypotension, headache, nausea
Nitroglycerin
Acts on Guanylate Cyclase
brings blood to ischemic areas, treats angina and angina prophylaxis, HF, hypertensive emergency
could cause dizziness, hypotension, flushing, severe headaches but tolerance occurs
prils
ACE inhibitors
ARBs
sartan
Statins
statins
loop diuertic
furosemide
Beta Blockers
elols
