- Myasthenia Gravis Agents
Description
Parenteral cholinesterase inhibitor
Used for diagnosing myasthenia gravis, assessing cholinesterase inhibitor therapy, differentiating cholinergic and myasthenic crises, and reversing effects of nondepolarizing neuromuscular blockers after surgery; adjunct to atropine for treating respiratory depression associated with curare overdosage
Drug of choice for diagnosing myasthenia gravis because of rapid action and short duration of effect
Indications
Indicated for myasthenia gravis diagnosis.
For the assessment of cholinesterase inhibitor therapy in patients with myasthenia gravis.
For use to differentiate a myasthenic crisis from a cholinergic crisis (e.g., myasthenic crisis diagnosis).
For use in nondepolarizing neuromuscular blockade reversal.
For the treatment of paroxysmal supraventricular tachycardia (PSVT) or diagnosis of supraventricular arrhythmias
Contraindications
Hypersensitivity
Asthma, Peptic ulcer disease, Hyperthyroidism, Breast-feeding

Pregnancy and Lactation
The manufacturer warns that the safe use of edrophonium during breast-feeding has not been established. However, the drug’s effect is manifested within 30 to 60 seconds after injection and lasts an average of 10 minutes. Edrophonium is ionized at physiological pH and is therefore not believed to be excreted in breast milk. Consider the benefits of breast-feeding, the risk of potential infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally administered drug, healthcare providers are encouraged to report the adverse effect to the FDA.
