Final answer:
The most commonly prescribed digitalis preparation for treating CHF is digoxin. It is used to relieve heart failure symptoms and to slow down certain irregular heartbeats, such as atrial fibrillation. Doctors monitor blood levels and kidney function to ensure safety and effectiveness.
Step-by-step explanation:
The most commonly prescribed digitalis preparation for treating congestive heart failure (CHF) is digoxin. Digoxin is used to relieve symptoms of heart failure when patients are not responding adequately to ACE inhibitors and diuretics. It is also prescribed to slow down certain types of irregular heartbeats, such as atrial fibrillation, which can accompany heart failure.
Aside from digoxin, there are also other medications used to treat cardiovascular conditions, including medications for high blood pressure and chest pain (angina) related to reduced blood supply to the heart muscle, as well as treatment for various arrhythmias. In some cases, drugs like anti-platelet agents and anticoagulants may be used concurrently with digoxin to reduce the risk of complications arising from arrhythmias.
It's important for patients taking digoxin to have their blood levels of the drug monitored regularly, as the therapeutic index is narrow, and the risk of toxicity is a concern. Physicians also monitor kidney function and electrolytes like potassium and magnesium, as fluctuations in these can affect digoxin's action and safety.
