Reversol - General Information

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. [PubChem]


Pharmacology of Reversol

Reversol 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. Reversol's pharmacologic action is due primarily to the inhibition or inactivation of acetylcholinesterase at sites of cholinergic transmission. Muscarinic 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 muscarinic receptors, so that the muscle becomes less responsive to nervous stimulation. Reversol chloride increases the amount of acetylcholine at the nerve endings. Increased levels of acetyl choline allow the remaining receptors to function more efficiently.


Reversol for patients


Reversol Interactions

Care should be given when administering this drug to patients with symptoms of myasthenic weakness who are also on anticholinesterase drugs. Since symptoms of anticholinesterase overdose (cholinergic crisis) may mimic underdosage (myasthenic weakness), their condition may be worsened by the use of this drug.


Reversol Contraindications

Known hypersensitivity to anticholinesterase agents; intestinal and urinary obstructions of mechanical type.


Additional information about Reversol

Reversol Indication: 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.
Mechanism Of Action: Reversol 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 a type of receptor called muscarinic receptors. When stimulated, these receptors have a range of effects.
