Methacholine chloride

Description:

Methacholine chloride is a synthetic quaternary ammonium compound primarily used in medical applications, particularly in the diagnosis of asthma. It acts as a muscarinic acetylcholine receptor agonist, leading to bronchoconstriction and increased airway resistance, which makes it useful for bronchial provocation tests. The substance appears as a white to off-white crystalline powder and is soluble in water, which facilitates its administration via inhalation or injection. Methacholine chloride has a relatively low toxicity profile when used as directed, but it can cause side effects such as bronchospasm, coughing, and gastrointestinal disturbances. Its chemical formula is C7H16ClN, and it has a molecular weight of approximately 151.67 g/mol. Due to its pharmacological properties, methacholine is classified as a prescription medication and should be used under medical supervision. Proper storage conditions include a cool, dry place, away from light, to maintain its stability and efficacy.
