Digoxin is primarily prescribed to treat which condition?

Digoxin is primarily prescribed to treat congestive heart failure because it helps improve the efficiency and contraction strength of the heart, thereby enhancing cardiac output. This medication achieves that by inhibiting the sodium-potassium ATPase pump, which increases intracellular calcium concentrations, leading to stronger heart contractions. In patients with congestive heart failure, this increased contractility is essential for alleviating symptoms such as shortness of breath and fatigue associated with the condition.

While digoxin can also be indicated for certain types of arrhythmias, its primary role in managing congestive heart failure makes this condition the most relevant option. Other alternatives like angina pectoris or hypertension typically require different classes of medications for effective treatment.
