InjectionClinical Overview
Neostigmine Methylsulphate is a synthetic quaternary ammonium reversible anticholinesterase agent on the WHO Model List of Essential Medicines. It inhibits acetylcholinesterase at the neuromuscular junction and postganglionic parasympathetic synapses, accumulating acetylcholine and competitively displacing non-depolarizing muscle relaxants. Indicated parenterally for the reversal of non-depolarizing neuromuscular blockade post-surgery, myasthenia gravis crisis, and non-obstructive postoperative paralytic ileus/urinary retention.

Usage Guidelines
Administered by anesthesiologists or intensive care physicians by slow intravenous injection, always preceded or accompanied by an anticholinergic agent (atropine or glycopyrrolate) to prevent severe muscarinic bradycardia and bronchospasm. Continuous monitoring of heart rate and respiration is mandatory.
General Administration Advice: Adhere strictly to the prescribed dosage, frequency, and treatment course. For oral medications, swallow with sufficient water. Never stop antibiotics, psychiatric medications, or antihypertensives abruptly without clinical direction.
Possible Side Effects
Common: Excessive salivation, nausea, diarrhea, abdominal cramps, sweating, muscle fasciculations. Rare/Severe: Severe bradycardia, heart block, cardiac arrest, cholinergic crisis, and severe bronchospasm.
*Note: Individual physiological responses vary. While many patients experience few or no side effects, notify your treating physician if adverse reactions persist or if hypersensitivity (angioedema, skin rash, dyspnea) occurs.
Precautions & Warnings
Must always be co-administered with atropine or glycopyrrolate to counteract potentially fatal muscarinic bradycardia and asystole. Contraindicated in mechanical intestinal or urinary obstruction and peritonitis. Resuscitation equipment must be present.
