Watch: How to Take Digoxin Safely & Check Pulse (3 m 41 s)
Fresh‑Voice Introduction
Digitalis leaf extracts have saved failing hearts since 1785, yet modern GMP lets Lanoxin® 0.25 mg deliver digoxin with milligram‑level precision—critical because the therapeutic window opens at 0.8 ng/mL and toxicity lurks beyond 2.0 ng/mL. GSK’s Indian plant presses each score‑lined tablet with micro‑crystalline cellulose and sodium starch glycolate to achieve Q > 85 % dissolution by 30 min, while UV‑HPLC tests certify ±3 % potency variance.
Cost remains the other marvel: Indian strips price at ₹28 (~$0.34) for 10 tablets, slashing 70 % off Western generics. Once‑daily dosing after breakfast stabilizes AF ventricular rates and injects extra inotropy into HFrEF patients who continue to feel fatigued on β‑blockers and ACE/ARBs alone.
Mechanism Highlights
| Pathway | Result | Clinical Win |
| Na⁺/K⁺‑ATPase inhibition | ↑ intracellular Ca²⁺ | + inotropy (CO ↑ 17 %) |
| Vagal tone boost | ↓ AV nodal conduction | HR −12 bpm in AF |
| Baroreflex reset | Mild natriuresis | Edema relief adjunct |
Half‑life ~ 36 h (normal kidneys); renal clearance key.
