Dược Lực Học :
Methacholine acts as a non-selective muscarinic receptor agonist to stimulate the parasympathetic nervous system. It is highly active at all of the muscarinic receptors
Cơ Chế Tác Dụng :
Methacholine acts as a non-selective muscarinic receptor agonist to stimulate the parasympathetic nervous system. It is most commonly used for diagnosing bronchial hyperreactivity, using the bronchial challenge test. Through this test, the drug causes bronchoconstriction and people with pre-existing airway hyperreactivity, such as asthmatics, will react to lower doses of drug.
By agonizing the muscarinic receptors, this drug induces bronchoconstriction. This bronchoconstriction is used as a test in asthmatics and in bronchial hyperreactivity.
Chỉ Định :
It is most commonly used for diagnosing bronchial hyperreactivity, using the bronchial challenge test.
Tương Tác Thuốc :
-
Betaxolol
Beta-Blockers like betaxolol may worsen brochoconstriction and decrease the effectiveness of agents used to treat the resulting bronchoconstriction. Use of betaxolol and methacholine concomitantly is contraindicated.
