Mestinon Disease Interactions
There are 7 disease interactions with Mestinon (pyridostigmine).
Cholinesterase inhibitor (applies to Mestinon) bradycardia
Major Potential Hazard, High plausibility. Applicable conditions: Arrhythmias
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 in patients with and without cardiac abnormalities. Atropine may be used to reverse bradycardia produced by cholinesterase inhibitors.
Cholinesterase inhibitor (applies to Mestinon) bronchospasm
Major Potential Hazard, High plausibility. Applicable conditions: Asthma, Chronic Obstructive Pulmonary Disease
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. Monitoring respiratory function during dosage initiation and adjustment is recommended. Use of atropine along with discontinuation of the cholinesterase inhibitor may be required for serious respiratory distress. Neostigmine may produce more severe muscarinic side effects than does pyridostigmine and ambenonium. However, the duration of action is longest for ambenonium and shortest for edrophonium. Echothiophate iodide ophthalmic may be systemically absorbed and cautious use is recommended in these patients.
Cholinesterase inhibitor (applies to Mestinon) coronary artery disease
Major Potential Hazard, High plausibility. Applicable conditions: Ischemic Heart Disease
The use of cholinesterase inhibitors has been associated with a constriction of coronary arteries. Therapy with cholinesterase inhibitors should be administered cautiously in patients with coronary artery disease.
Cholinesterase inhibitor (applies to Mestinon) parkinsonism
Major Potential Hazard, High plausibility.
Cholinesterase inhibitors should be used with caution in patients with parkinsonism. Some of these drugs might be contraindicated in these patients (refer to specific prescribing information). Symptoms of Parkinson's disease may be exacerbated with the increase in cholinergic activity. Caregivers and patients should be advised.
Cholinesterase inhibitor (applies to Mestinon) PUD
Major Potential Hazard, High plausibility. Applicable conditions: Peptic Ulcer
The use of cholinesterase inhibitors is associated with an increase in gastric acid secretion and gastric contractions. Therapy with cholinesterase inhibitors should be administered cautiously in patients with peptic ulcer disease.
Cholinesterase inhibitor (applies to Mestinon) seizures
Major Potential Hazard, High plausibility.
Cholinesterase inhibitors have been associated with convulsions and tremor. Therapy with cholinesterase inhibitors should be administered cautiously in patients with seizure disorders.
Cholinesterase inhibitor (applies to Mestinon) hyperthyroidism
Moderate Potential Hazard, High plausibility.
Many of the manifestations of hyperthyroidism may be exacerbated by increased levels of acetylcholine produced by cholinesterase inhibitors. Therapy with cholinesterase inhibitors should be administered cautiously to patients with hyperthyroidism. Monitoring of thyroid levels is recommended.
