Enlon (edrophonium) Disease Interactions
There are 5 disease interactions with Enlon (edrophonium):
Cholinesterase Inhibitor (Includes Enlon) ↔ Bradycardia
Severe Potential Hazard, High plausibility
Applies to: Arrhythmias, Heart Block
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 (Includes Enlon) ↔ Bronchospasm
Severe Potential Hazard, High plausibility
Applies to: Chronic Obstructive Pulmonary Disease, 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. Monitoring respiratory function during dosage initiation and adjustment are 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 (Includes Enlon) ↔ Parkinsonism
Severe Potential Hazard, High plausibility
Applies to: Parkinsonism
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 (Includes Enlon) ↔ Pud
Severe Potential Hazard, High plausibility
Applies to: 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 (Includes Enlon) ↔ Seizures
Severe Potential Hazard, High plausibility
Applies to: Seizures
Cholinesterase inhibitors have been associated with convulsions and tremor. Therapy with cholinesterase inhibitors should be administered cautiously in patients with seizure disorders.

Drug Interaction Classification
The classifications below are a general guideline only. It is difficult to determine the relevance of a particular drug interaction to any individual given the large number of variables.
| Major | Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit. |
| Moderate | Moderately clinically significant. Usually avoid combinations; use it only under special circumstances. |
| Minor | Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan. |
