Lanoxin, a brand name for digoxin, is recognized as a digitalis medicine. Digitalis refers to a group of medications derived from the digitalis plant, primarily used to treat various heart conditions, including atrial fibrillation and heart failure. Digoxin works by increasing the force of heart contractions and regulating heart rhythms, making it effective for patients who need improved cardiac function.

When considering the other medications listed, Bumex (bumetanide) is a diuretic used for fluid retention, Zestril (lisinopril) is an angiotensin-converting enzyme (ACE) inhibitor for hypertension and heart failure, and Adalat (nifedipine) is a calcium channel blocker used for hypertension and angina. None of these medications are classified as digitalis agents, which highlights the specific role of Lanoxin in managing heart-related issues. This distinction emphasizes the importance of understanding the pharmacological categories of medications in the context of patient care.
