BACKGROUND:
Cholinomimetic agents include bethanechol, carbachol, pilocarpine, and methacholine.
Bethanechol activates smooth muscle of bladder and bowel.
Carbachol is a synthetic acetylcholine used in ophthalmology.
Pilocarpine is a potent stimulator of salivation, lacrimation, and perspiration.
Methacholine is used for diagnostics in asthma, as it stimulates muscarinic receptors in airway when inhaled.

QUESTIONS:
What is the airway's reaction to the methacholine challenge test?
What actions make pilocarpine useful in both open and closed angle glaucomas?
What is the result of ocular application of carbachol?
The actions of bethanechol make it useful in which conditions?
