About Simplist Neostigmine Methylsulfate Injection, USP

Neostigmine Methylsulfate Injection, a cholinesterase inhibitor, is indicated for intravenous use for reversal of the effects of nondepolarizing neuromuscular blocking agents (NMBA) after surgery.

Important Safety Information 

An anticholinergic agent, e.g., atropine sulfate or glycopyrrolate, should be administered prior to or concomitantly with neostigmine methylsulfate. 

Neostigmine is contraindicated in patients with:
•    Hypersensitivity to neostigmine. 
•    Peritonitis or mechanical obstruction of the urinary or intestinal tracts. 

Neostigmine has been associated with bradycardia: Atropine or glycopyrrolate should be administered prior to administration of neostigmine methylsulfate injection to lessen risk of bradycardia.

Coexisting Conditions: Patients with known cardiac disease, cardiac arrhythmias, or recent coronary artery occlusion may be particularly sensitive to the hemodynamic effects of neostigmine; their blood pressure and electrocardiogram should be continuously monitored with the initiation of neostigmine treatment and for a duration sufficient to assure hemodynamic stability.

Neuromuscular Dysfunction: Can occur if large doses of neostigmine methylsulfate are administered when there is minimal neuromuscular blockade; reduce the dose if recovery from neuromuscular blockade is nearly complete. 

The most common adverse reactions include bradycardia, nausea, and vomiting.
