Edrophonium ion
Edrophonium ion Uses, Dosage, Side Effects, Food Interaction and all others data.
A rapid-onset, short-acting cholinesterase inhibitor used in cardiac arrhythmias and in the diagnosis of myasthenia gravis. It has also been used as an antidote to curare principles.
Edrophonium ion is a short and rapid-acting anticholinesterase drug. Its effect is manifest within 30 to 60 seconds after injection and lasts an average of 10 minutes. Edrophonium ion's pharmacologic action is due primarily to the inhibition or inactivation of acetylcholinesterase at sites of cholinergic transmission. Nicotinic acetylcholine (nAChR)receptors are found throughout the body, especially on muscle. Stimulation of these receptors causes to muscle contraction. In myasthenia gravis the body's immune system destroys many of the nicotinic acetylcholine receptors, so that the muscle becomes less responsive to nervous stimulation. Edrophonium ion chloride increases the amount of acetylcholine at the nerve endings. Increased levels of acetylcholine allow the remaining receptors to function more efficiently.

Uses
Edrophonium ion is a cholinesterase inhibitor used to diagnose and evaluate myasthenia gravis.
For the differential diagnosis of myasthenia gravis and as an adjunct in the evaluation of treatment requirements in this disease. It may also be used for evaluating emergency treatment in myasthenic crises.
Edrophonium ion is also used to associated treatment for these conditions: Myasthenia Gravis, Neuromuscular Blockade, Respiratory Depression
How Edrophonium ion works
Edrophonium ion works by prolonging the action acetylcholine, which is found naturally in the body. It does this by inhibiting the action of the enzyme acetylcholinesterase. Acetylcholine stimulates nicotinic and muscarinic receptors. When stimulated, these receptors have a range of effects.
Toxicity
With drugs of this type, muscarine-like symptoms (nausea, vomiting, diarrhea, sweating, increased bronchial and salivary secretions and bradycardia) often appear with overdosage (cholinergic crisis).
