Methacholine
  

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.
