Donecept Tablets Precautions
Precaution
Because of their pharmacological action, cholinesterase inhibitors may have vagotonic effects on heart rate (e.g., bradycardia). The potential for this action may be particularly important to patients with sick sinus syndrome or other supraventricular cardiac conduction conditions, such as sinoatrial or atrioventricular block. There have been reports of syncope and seizures. In investigating such patients the possibility of heart block or long sinusal pauses should be considered.
