Labetalol-induced hyperkalemia in acute aortic dissection: A rare but clinically relevant adverse effect.
BACKGROUND Hyperkalemia is a potentially life-threatening electrolyte abnormality often associated with renin-angiotensin-aldosterone system (RAAS) inhibitors, renal dysfunction, or potassium-sparing agents. Non-selective beta-blockers, including labetalol, may also precipitate hyperkalemia through beta-2 (β-2)-adrener...
