CS-15
Safety Findings and ConclusionsCHARM Added As expected, due to the greater RAAS inhibition,
rates of hypotension, abnormal renal function, and hyperkalemia were greater with candesartan
These predictable adverse events did not translate into any increases in all-cause hospitalization and/or mortality as well as sudden death, renal failure, or ventricular fibrillation
Candesartan is safe and generally well-tolerated by patients with CHF receiving evidence-based doses of ACE inhibitors
