Medicinal name:
  • Neostigmine 15 MG Oral Tablet [Prostigmin Bromide]

Prostigmin - Pharmacology:

Prostigmin is a parasympathomimetic, specifically, a reversible cholinesterase inhibitor. By interfering with the breakdown of acetylcholine, neostigmine indirectly stimulates both nicotinic and muscarinic receptors. It does not cross the blood-brain barrier.

Prostigmin Interactions

Certain antibiotics, especially neomycin, streptomycin and kanamycin, have a mild but definite nondepolarizing blocking action which may accentuate neuromuscular block. These antibiotics should be used in the myasthenic patient only where definitely indicated, and then careful adjustment should be made of adjunctive anticholinesterase dosage.

Local and some general anesthetics, antiarrhythmic agents and other drugs that interfere with neuromuscular transmission should be used cautiously, if at all, in patients with myasthenia gravis; the dose of Prostigmin may have to be increased accordingly.

Prostigmin Contraindications

Prostigmin is contraindicated in patients with known hypersensitivity to the drug. Because of the presence of the bromide ion, it should not be used in patients with a previous history of reaction to bromides. It is contraindicated in patients with peritonitis or mechanical obstruction of the intestinal or urinary tract.
