- Presumptive diagnosis of myasthenia gravis (MG): Patient is gently exercised until fatigued. Place indwelling catheter. Have atropine drawn up (0.02-0.04 mg/kg IV) in case cholinergic signs develop. Flush catheter with sterile saline, then immediately lightly exercise or encourage to rise.
- Presumptive diagnosis of myasthenia gravis (MG): Presumptive positive test results in transient improvement in clinical weakness.
- Presumptive diagnosis of myasthenia gravis (MG): Have atropine and endotracheal tube readily available in case of overdose.
- Presumptive diagnosis of myasthenia gravis (MG): Pre-treat with atropine (0.02-0.04 mg/kg IM or SC). In affected animals, paresis should resolve within one minute and effects should last for up to 15 minutes.

개요
에드로포늄은 속효성 주사용 항콜린에스테라제 약물로, 수의학에서는 주로 '텐실론 검사'를 통한 중증근무력증(MG)의 추정 진단에 사용됩니다. 비탈분극성 신경근 차단제의 작용을 역전시키거나 특정 상심실성 빈맥(SVT)을 치료하는 데도 사용할 수 있지만, 작용 시간이 매우 짧아 이러한 목적에는 네오스티그민과 같은 지속 시간이 더 긴 대체 약물이 더 실용적인 경우가 많습니다.
작용 기전
Edrophonium acts as a rapid, reversible inhibitor of the enzyme acetylcholinesterase.
Mechanism of Action: Edrophonium briefly attaches to acetylcholinesterase → inhibits its hydrolytic activity → acetylcholine accumulates in the synaptic cleft → prolonged and increased stimulation of nicotinic and muscarinic receptors.
In patients with myasthenia gravis, the sudden surge of acetylcholine temporarily overcomes the autoimmune blockade/destruction of nicotinic receptors at the neuromuscular junction, leading to a rapid (but transient) return of muscle strength. Systemically, acetylcholine accumulation also causes parasympathomimetic effects including miosis, increased intestinal muscle tone, bronchoconstriction, salivation, and bradycardia.

주의
Use with extreme caution in patients with bradycardias or atrioventricular block. Adequate monitoring and treatment must be available. Always have IV atropine and an endotracheal tube readily available before administering edrophonium. Safety during pregnancy is not established (FDA Category C); use only when clearly necessary.
약물 상호작용
Antagonizes the muscarinic effects of edrophonium. Concurrent use should be done cautiously as atropine can mask the early clinical signs of a cholinergic crisis.
Theoretically may have additive cholinergic effects when used with edrophonium.
Edrophonium's cardiac effects may be increased; excessive slowing of heart rate (bradycardia) may occur.
Edrophonium may prolong the Phase I block of these agents.
Edrophonium antagonizes the neuromuscular blocking actions of these agents.
모니터링
- Cholinergic adverse effects (heart rate, respiratory rate/effort, salivation)
- Improvement of paresis (for 1-15 minutes) for presumptive diagnosis of myasthenia gravis
약동학
흡수
Only effective when given parenterally. After IV administration, effects on skeletal muscle begin within one minute.
분포
Not well described in veterinary literature.
대사
Exact metabolic fate has not been well described.
배설
Excretion characteristics are not well described. Clinical effects generally persist for up to 10 minutes, though myasthenic patients may experience longer-lasting effects after the first dose.
과다투여
Overdosage of edrophonium may induce a cholinergic crisis.
Clinical Signs of Toxicity (SLUDGE syndrome and beyond):
- GI: Nausea, vomiting, diarrhea, salivation
- Respiratory: Increased bronchial secretions, bronchospasm, pulmonary edema, respiratory paralysis
- Ophthalmic: Miosis, blurred vision, lacrimation
- Cardiovascular: Bradycardia or tachycardia, cardiospasm, hypotension, cardiac arrest
- Musculoskeletal: Muscle cramps, profound weakness, sweating (in animals with sweat glands)
Treatment: Consists of immediate respiratory and cardiac supportive therapy. Administer atropine IV to counteract severe muscarinic effects.

보호자 정보
- 임상 환경 전용: 에드로포늄은 통제된 동물병원 환경에서만 투여되는 특수 진단용 약물입니다.
- 목적: 주로 심각한 근육 약화를 유발하는 중증근무력증을 진단하는 데 도움을 주는 신속하고 일시적인 검사로 사용됩니다.
- 예상되는 상황: 검사 중 수의사가 반려동물의 상태를 주의 깊게 모니터링할 것입니다. 침 흘림, 구토, 배뇨 또는 심박수 변화와 같은 짧은 부작용이 발생할 수 있으나, 수의료진은 이러한 상황 발생 시 즉각적으로 대처할 준비가 되어 있습니다.
