digoxin LANOXIN (cardiotonic) *action inhibits the sodium potassium ATPase, which makes more calcium available for contractile proteins, resulting in ^cardiac output(positive inotropic effect); increases force of contraction; decreases HR (- chronotropic effect); decreases AV conduction speed
digoxin LANOXIN (cardiotonic) *side effects cns: h/a, drowsiness, apathy, confusion, disorientation, fatigue, depression, hallucinations cv: dysrhythmias, hypotension, bradycardia, AV block eent: blurred vision, yellow-green halos, photophobia, diplopia gi: n/v, anorexia, ab pain, diarrhea
digoxin LANOXIN (cardiotonic) *Assess - apical pulse for 1min. if <60 adult or <90 infant, take again in 1hr. - I&O ration, daily weight, turgor, lung sounds, edema - cardiac status: apical, charater, rate, rhythm
digoxin LANOXIN (cardiotonic) *Pt. Teaching - dont stop abruptly-take as ordered, monitor HR. - avoid OTC meds, herb remedies-many adverse s/d, dont take antacid. - notify dr: loss appetite, lower ab pain, diarrhea, weakness, drowsiness, h/a, blurred or yellow vision, rash, depression, toxicity
CARDIOTONICS aka cardiac glycoside Make heart beat stronger and slower. action: increase strength or force contraction(pumping) of heart muscle(myocardium). use to treat heart failure, arrhythmias.

DIURETICS reduce BP by producing sodium and water loss and lowering the tone or rigidity of the arteries
CALCIUM CHANNEL BLOCKERS diltiazem CARDIZEM reduce peripheral resistance in arms and legs through smooth muscle relaxation and vasodilation.
BETA ANDRENERGIC BLOCKERS metoprolol LOPRESSOR andrenergic inhibitors; block beta1&2 impulses, wide range of s/e
