This K-pump is responsible for maintaining the intracellular environment throughout the body by moving potassium ions into cells and sodium ions out by inhibiting Na-K ATPase. -Digoxin therapy serum concentrations •CHF (0.8 - 2.0 ng/mL) •Arrhythmias (1.5-2.5 ng/mL) •Adverse effects are more common in patients with low potassium /hypokalemia since digoxin normally competes with K+ ions for the same binding site on the Na+-K+-ATPase pump Digoxin is derived from the leaves of a digitalis plant. Common side effects of Levitra include facial flushing (reddening), headaches, stomach upset, diarrhea, flu-like symptoms, and nausea.

These typically cause people to urinate, thereby depleting some of the fluid from the body. This means that sodium ion efflux (loss of sodium from the cell) is delayed, resulting in local accumulation of sodium ions near the cell membrane. they may experience toxicity at digoxin levels lower than the usually accepted upper limit of 2–per Lexicomp. She is compliant with her medications, which include digoxin (Lanoxin) 0.125 mg daily, furosemide (Lasix) 40 mg daily, and potassium (K-Dur) 20 mEq daily.
