Anticoagulants and Antiarrhythmics

Front

Warfarin (Coumadin)

Back

Anticoagulant: A medication that helps prevent blood clots by inhibiting the synthesis of vitamin K-dependent clotting factors. It is commonly used to reduce the risk of stroke, deep vein thrombosis (DVT), and pulmonary embolism.

Front

Heparin

Back

Anticoagulant: A fast-acting blood thinner that prevents clot formation by enhancing the activity of antithrombin III, which inactivates thrombin and other clotting factors. It is often used in hospital settings for immediate anticoagulation.

Front

Enoxaparin (Lovenox)

Back

Anticoagulant: A low molecular weight heparin that prevents blood clots by inhibiting factor Xa and thrombin. It is used to prevent and treat DVT and pulmonary embolism, often after surgery or immobilization.

Front

Apixaban (Eliquis)

Back

Anticoagulant: An oral anticoagulant that directly inhibits factor Xa, reducing the formation of blood clots. It is prescribed to prevent stroke and systemic embolism in patients with atrial fibrillation and to treat or prevent DVT and pulmonary embolism.

Front

Rivaroxaban (Xarelto)

Back

Anticoagulant: An oral direct factor Xa inhibitor that prevents blood clot formation. It is used for stroke prevention in atrial fibrillation, and for treating and preventing DVT and pulmonary embolism.

Front

Dabigatran (Pradaxa)

Back

Anticoagulant: An oral direct thrombin inhibitor that prevents clot formation by blocking thrombin activity. It helps reduce the risk of stroke and systemic embolism in atrial fibrillation and treats or prevents DVT and pulmonary embolism.

Front

Amiodarone

Back

Antiarrhythmic: A medication used to treat and prevent various types of serious irregular heartbeats (arrhythmias). It works by prolonging the cardiac action potential and refractory period, stabilizing heart rhythm.

Front

Digoxin

Back

Antiarrhythmic/cardiac glycoside: A drug that increases the force of heart contractions and slows the heart rate by affecting the electrical conduction system. It is used to treat heart failure and certain types of arrhythmias like atrial fibrillation.

Front

Sotalol

Back

Antiarrhythmic: A beta-blocker with antiarrhythmic properties that helps control abnormal heart rhythms by blocking beta-adrenergic receptors and prolonging the cardiac action potential.

Front

Procainamide

Back

Antiarrhythmic: A medication that treats ventricular and supraventricular arrhythmias by blocking sodium channels, which slows electrical conduction in the heart and stabilizes rhythm.
