Digoxin is a cardiac glycoside medication that is used to treat certain heart conditions. It is derived from the plant digitalis and its active ingredient is Digoxin. The drug works by inhibiting the sodium-potassium atpase pump in cardiac muscle cells. This inhibition increases intracellular sodium levels which indirectly raises intracellular calcium. The rise in calcium enhances the force of myocardial contraction and improves cardiac output. Digoxin also slows the conduction of electrical impulses through the atrioventricular node. By regulating heart rate and rhythm it helps manage atrial fibrillation and heart failure. The overall therapeutic effect is a more efficient pumping action of the heart.

Digoxin is a cardiac glycoside used to strengthen heart contractions and control irregular heartbeats. It works by inhibiting sodium pumps in heart cells which increases intracellular sodium and indirectly raises calcium levels. The elevated calcium enhances myocardial contractility allowing the heart to pump more effectively. This mechanism also slows the electrical conduction through the atrioventricular node which helps regulate atrial fibrillation. Pharmacodynamically Digoxin has a narrow therapeutic window where small changes in blood levels can markedly alter its effects. Its absorption is slow and variable but it binds strongly to cardiac tissue and accumulates with repeated dosing. The drug's half-life is long allowing once-daily dosing but requires careful monitoring of serum concentrations.

Digoxin is a medication used to treat certain heart conditions. It works by affecting the heart's rhythm and blood flow. Some common side effects include nausea and loss of appetite. Patients may also experience visual disturbances such as blurred vision. Dizziness and weakness are frequently reported during treatment. Irregular heartbeats can occur if drug levels become too high.

One frequent reaction is nausea, which some patients experience shortly after taking the drug. Another common side effect is visual disturbances such as blurred or yellow-colored vision. Patients may also notice fatigue or general weakness during treatment. Irregular heartbeats or palpitations can occur when blood levels become too high. Digestive symptoms like loss of appetite or diarrhea are reported by some individuals. Elevated levels may lead to confusion or dizziness, especially in older adults.
