Sotalar™ 40 mg (Sotalol) — Complete Anti‑arrhythmia Guide
“When rhythm control is essential but amiodarone is too toxic, low‑dose sotalol steps up—provided QT is watched.” — Dr Neeraj Rao, DM Cardiac Electrophysiology, London | Hyderabad
📺 Video Overview
Introduction
Reining in rogue cardiac rhythms with β‑blockade plus K⁺‑channel hold.
Catheter ablation and DOACs dominate atrial‑fibrillation headlines, yet pharmacologic rhythm control persists for millions lacking cath‑lab access. Sotalol’s dual action—class III K⁺‑channel blockade and class II anti‑adrenergic—prolongs refractory periods while damping sympathetic triggers. Cipla’s Sotalar™ 40 mg targets initiation titration: begin inpatient (or monitored OP) at 40 mg BID, adjust by QTc. Once steady, many Asian phenotypes maintain sinus on 80–120 mg/day, avoiding amiodarone’s thyroid/lung baggage. (Full 3 000‑word intro in canvas expands epidemiology, guideline niches, and pharmacoeconomics.)
Mechanism Snapshot
| Action | Channel / Receptor | Electrophysiologic Outcome |
| IKr blockade | Delays phase‑3 repolarisation | ↑ APD & ERP, ↓ re‑entry |
| β‑1/β‑2 antagonism | ↓ cAMP in nodal tissue | ↓ AV nodal conduction & HR |
| Result | QTc prolong ≈ 20 ms @ 80 mg | Suppresses AF/VT but torsade risk |
Half‑life ≈ 12 h; renally cleared—dose‑adjust for CrCl < 60 mL/min.

Safety Dashboard
| Tier | Issue | Rate | Mitigation |
| 🟢 Fatigue / brady | 6 % | Dose ↓; add pacing if needed | |
| 🟡 QTc > 500 ms | 2 % | Hold dose; correct K⁺ Mg²⁺ | |
| 🟠 Torsade de pointes | 0.4 % | IV Mg, pacing, DC shock | |
| 🔴 Bronchospasm (COPD) | 0.5 % | Switch to amio/dofetilide |
CI: Baseline QTc > 450 ms, CrCl < 20, uncomp HF, asthma, AV block w/out pacer.
