## First-Line Pharmacotherapy in Decompensated Alcoholic Cirrhosis **Key Point:** Non-selective beta-blockers (NSBBs) like propranolol are the gold standard for primary and secondary prophylaxis of variceal bleeding in cirrhosis and reduce overall mortality in portal hypertension. ### Mechanism of Action Propranolol reduces portal pressure by: 1. Decreasing cardiac output (β1-blockade) 2. Reducing splanchnic blood flow (β2-blockade of splanchnic vasodilation) 3. Net reduction in portal venous pressure by 20–30% ### Clinical Evidence - **Survival benefit:** NSBBs reduce mortality in decompensated cirrhosis independent of variceal bleeding prevention - **Variceal prophylaxis:** Reduces risk of first variceal bleed by ~45% and rebleeding by ~40% - **Recommended in:** All cirrhotic patients with esophageal varices or portal hypertension signs **High-Yield:** Propranolol is initiated at 20–40 mg BD and titrated to achieve a 25% reduction in heart rate or systolic BP, or a resting HR of 55–60 bpm. ### Role of Other Agents in This Case | Drug | Indication | Limitation in This Case | |------|-----------|-------------------------| | **Spironolactone** | Ascites management (aldosterone antagonist) | Does not reduce portal pressure; used *with* NSBBs for ascites, not as monotherapy | | **Lactulose** | Hepatic encephalopathy (osmotic laxative, ↓ ammonia) | Treats encephalopathy but does not address underlying portal hypertension or improve survival | | **Silymarin** | Antioxidant, hepatoprotective | No proven survival benefit in established cirrhosis; used in early alcoholic hepatitis only | **Clinical Pearl:** In decompensated cirrhosis with ascites, the combination of propranolol (for portal hypertension) + spironolactone (for ascites) + lactulose (for encephalopathy) is standard. However, the question asks for the single drug with the greatest impact on survival — that is propranolol. **Warning:** Do not confuse propranolol's role in variceal prophylaxis with treatment of acute variceal bleeding (which requires variceal band ligation + octreotide).
