Study Notes
Antidysrhythmic and Coagulation Modifier Drugs Summary
- Adverse effects of amiodarone hydrochloride include pulmonary toxicity, thyroid disorders, bradycardia, hypotension, ataxia, QT prolongation, and dermatologic reactions.
- Ibutilide fumarate adverse effects include ventricular tachycardia, hypotension, and headache.
- Sotalol hydrochloride adverse effects include bradycardia, chest pain, palpitations, and weakness.
- Class 4 drugs, such as diltiazem hydrochloride and verapamil hydrochloride, are calcium channel blockers used for hypertension and angina.
- Class 4 drugs are indicated for paroxysmal supraventricular tachycardia and rate control for atrial fibrillation and flutter.
- Adverse effects of calcium channel blockers include constipation, bradycardia, heart block, and hypotension.
- Unclassified antidysrhythmic drugs, like adenosine, work by slowing electrical conduction and are used for paroxysmal supraventricular tachycardia.
- Nursing implications for amiodarone include monitoring for GI upset, photosensitivity, and emphasizing the importance of eye protection.
- General contraindications for antidysrhythmics include drug allergy and certain heart conditions.
- Anticoagulants prevent clot formation and are indicated for conditions like MI, unstable angina, atrial fibrillation, and presence of indwelling devices.
- Warfarin is indicated for prevention of strokes, heart attacks, deep vein thrombosis, and pulmonary embolism.
- Unfractionated heparins, LMWHs, direct thrombin inhibitors, and factor Xa inhibitors are used for prevention and treatment of clot-related events.
Digoxin Toxicity and Antiarrhythmic Drugs: Mechanisms, Indications, and Adverse Effects
- Digoxin toxicity can lead to hyperkalemia and life-threatening cardiac dysrhythmias
- Life-threatening digoxin overdose is defined as more than 10 mg in adults and more than 4 mg in children
- Class 1a antiarrhythmic drugs, such as procainamide and quinidine, stabilize the membrane and depress phase 0 of the action potential
- Class 1a drugs are indicated for atrial fibrillation, premature atrial contractions, premature ventricular contractions, ventricular tachycardia, and Wolff-Parkinson-White syndrome
- Class 1b drugs, like lidocaine hydrochloride and phenytoin, act preferentially on ischemic myocardial tissue and are indicated for ventricular dysrhythmias
- Lidocaine solutions need to be used with extreme caution, and vials are labeled for cardiac or non-cardiac use
- Class 1c drugs, including flecainide acetate and propafenone hydrochloride, produce a more pronounced blockage of the sodium channel and significantly slow conduction in the heart
- Class 2 drugs, beta blockers, decrease heart rate and reduce myocardial contractility
- Sotalol has both class 2 and class 3 properties and is indicated for both supraventricular and ventricular dysrhythmias
- Class 3 drugs, such as amiodarone and dronedarone hydrochloride, increase the action potential duration by prolonging repolarization in phase 3
- Class 3 drugs are used for life-threatening ventricular tachycardia or fibrillation and atrial fibrillation or flutter resistant to other drugs
- Adverse effects of antiarrhythmic drugs include hypotension, dysrhythmia, dizziness, nausea, and visual disturbances
