pyridostigmine

2D structure

Overview

Generic Names: Pyridine N-Oxide; Pyridostigmine Bromide; Pyridostigmine Bromine; Pyridostigminum
Trade Names: Mestinon; Mestinon-SR; Regonol
PharmGKB Accession Id: PA451185

Description

A cholinesterase inhibitor with a slightly longer duration of action than neostigmine. It is used in the treatment of myasthenia gravis and to reverse the actions of muscle relaxants. PubChem (source: Drug Bank)

Indication

For the treatment of myasthenia gravis. (source: Drug Bank)

ATC Therapeutic Category

  • N07AA:Anticholinesterases

Pharmacology, Interactions, and Contraindications

Mechanism Of Action

Pyridostigmine inhibits acetylcholinesterase in the synaptic cleft by competing with acetylcholine for attachment to acetylcholinesterase, thus slowing down the hydrolysis of acetylcholine, and thereby increases efficiency of cholinergic transmission in the neuromuscular junction and prolonges the effects of acetylcholine. (source: Drug Bank)

Pharmacology

Pyridostigmine is a parasympathomimetic and a reversible cholinesterase inhibitor. Since it is a quaternary amine, it is poorly absorbed in the gut and doesn't cross the blood-brain barrier. Pyridostigmine has a slightly longer duration of action than NEOSTIGMINE. It is used in the treatment of myasthenia gravis and to reverse the actions of muscle relaxants. (source: Drug Bank)

Food Interactions

Take with food to decrease adverse effects. (source: Drug Bank)

Absorption, Distribution, Metabolism, Elimination & Toxicity

Biotransformation

Hydrolysis by cholinesterases and by liver. (source: Drug Bank)

Absorption

Poorly absorbed from the GI tract with an oral bioavailability of 7.6 +/- 2.4%. (source: Drug Bank)

Isomeric SMILES Code:

C[n+]1cccc(c1)OC(=O)N(C)C (source: Drug Bank)
