WebApr 1, 2024 · Digoxin is used to treat congestive heart failure, usually in combination with a diuretic (water pill) and an angiotensin-converting enzyme (ACE) inhibitor. It is also used … WebHF, which calls into question a pure inotropic mechanism of action for the drug (7,8). Recent work suggests these favorable neurohormonal effects occur at low doses of digoxin (9), and that increasing the SDC beyond modest levels (i.e., 0.7 ng/ml) may not produce additional neuro-hormonal benefits (10).
