Interactions

May reduce effects of anticholinergics. May increase effects of cholinergic agonists. Increased risk of bradycardia with digoxin, diltiazem, verapamil or beta-blockers without intrinsic sympathomimetic activity. Increased muscle weakness and decreased response to anticholinesterases with corticosteroids. May increase effects of depolarising neuromuscular blockers. Effects may be antagonised by drugs with neuromuscular blocking activity e.g. aminoglycosides, clindamycin, colistin, cyclopropane, halogenated inhalational anaesthetics. Effects may be reduced by quinine, chloroquine, hydroxychloroquine, quinidine, procainamide, propafenone, lithium, beta-blockers. Possible additive toxicity with ophthalmic use of anticholinesterases e.g. ecothiopate.

Mechanism of Action

Neostigmine reversibly inhibits acetylcholinesterase and thus potentiates the nicotinic and muscarinic effects of acetylcholine. This facilitates the transmission of impulses across myoneural junction.
