Question | Answer |
Cardiac Glycosides Prototype | Digoxin (Lanoxin) |
Cardiac Glycosides MOA | Increase intracellular calcium (increases myocardial contractility, decreases rate of electrical conduction). |
Cardiac Glycosides Secondary Effects | Increase in coronary perfusion, promotion of dieresis, relief of symptoms of heart failure. |
Digoxin Indications | Heart failure, tachydysrhythmias. NEVER for ventricular dysrhythmias. |
Digoxin Adverse Effect | Very narrow therapeutic window, Hypokalemia increases it’s toxicity. |
Digoxin Nursing Implictions | Take at the same time each day, Don’t switch brands. |
Digoxin Toxicity | GI -Anorexia, nausea, vomiting, diarrhea. CV – Bradycardia, Heart blocks. CNS – Confusion, Visual disturbances (green or yellow halo’s) headaches, fatigue, malaise, convulsions. |
Digoxin Toxicity treatment | Digoxin immune fab (Digibind). |

Digoxin Interactions – LOTS, loop and thiazide diuretics, calcium channel blockers. | |
Three Types of Angina | Stable (predictable and manageable), Unstable (unpredictable, occur even at rest), Prinzmetals (spasms of coronary arteries that occur randomly, often in the middle of the night). |
Nitrates Prototype | Nitroglycerin (Nitrobid, Nitrostat, etc.) |
Nitrates MOA | Cause systemic vasodilation, potent dilating effect on coronary arteries. |
Nitrates Indications | Acute relief of ischemia/angina, prophylaxis in situations that may provoke angina, Long-term prophylaxis of angina. |
Nitrates Adverse Effects | Headaches, decreased blood pressure, tachycardia, orthostatic hypotension. |
Nitrates Contraindications/Cautions | Hypotension, Dehydration, Head trauma. |
Nitrates Interactions | sidenafil citrate (Viagra), other drugs that cause a decrease in blood pressure. |
