Edrophonium Chloride
Also known as: Tensilon, Enlon, Anticude, Camsilon, Reversol, Enlon-Plus
- **Clinical Setting Only:** Edrophonium is a specialized diagnostic drug that is only administered in a controlled veterinary hospital setting. - **Purpose:** It is primarily used as a rapid, temporary test to help diagnose myasthenia gravis, a condition causing severe muscle weakness. - **What to Expect:** Your veterinarian will closely monitor your pet during the test. Brief side effects such as drooling, vomiting, urination, or changes in heart rate can occur, but the veterinary team is prepared to treat these immediately if they arise.
Dosage must be set by your veterinarian for your specific pet. Never give human medication or another pet’s prescription without veterinary guidance.

Drug interactions
- Atropine: Antagonizes the muscarinic effects of edrophonium. Concurrent use should be done cautiously as atropine can mask the early clinical signs of a cholinergic crisis.
- Dexpanthenol: Theoretically may have additive cholinergic effects when used with edrophonium.
- Digoxin: Edrophonium's cardiac effects may be increased; excessive slowing of heart rate (bradycardia) may occur.
- Depolarizing Muscle Relaxants (e.g., succinylcholine, decamethonium): Edrophonium may prolong the Phase I block of these agents.
- Non-depolarizing Muscle Relaxants (e.g., pancuronium, tubocurarine, vecuronium, atracurium): Edrophonium antagonizes the neuromuscular blocking actions of these agents.
