Cardiovascular eventsBecause of their pharmacologic action, cholinesterase inhibitors have vagotonic effects on the sinoatrial (SA) and atrioventrical (AV) nodes, leading to bradycardia and AV block. These actions may be particularly important to patients with superventricular cardiac conduction disorders, or to patients taking other drugs concomitantly that significantly slow heart rate. In clinical trials, galantamine HBr was associated with more frequent reports of bradycardia and syncope vs placebo. Post marketed surveillance of marketed anticholinesterase inhibitors has shown that bradycardia and all types of heart block have been reported in patients both with and without known underlying cardiac conduction abnormalities. All patients should be considered at risk for adverse effects on cardiac conduction.
