Arrhythmia
Major:
physostigmine
PHYSostigmine has a major potential interaction with Arrhythmia.
Due to their pharmacological action, cholinesterase inhibitors can have a vagotonic effect on the sinoatrial and atrioventricular nodes producing bradycardia or heart block. Therapy with cholinesterase inhibitors should be administered cautiously in patients with preexisting bradycardia or underlying cardiac conduction abnormalities. Syncopal episodes have been reported. Atropine may be used to reverse bradycardia produced by cholinesterase inhibitors.
Asthma
Major:
physostigmine
PHYSostigmine has a major potential interaction with Asthma.
Cholinesterase inhibitors inhibit the hydrolysis of acetylcholine. The enhanced effect of acetylcholine produces constriction of the bronchi, increased bronchial secretions, and bronchospasm. Therapy with cholinesterase inhibitors should be administered cautiously in patients with respiratory dysfunction, history of asthma, or obstructive pulmonary disease. Respiratory function should be closely monitored for the occurrence of respiratory adverse reactions. Use of atropine along with discontinuation of the cholinesterase inhibitor may be required for serious respiratory distress.
