pilocarpine

This term is a specialized pharmacological agent used primarily in ophthalmology and otolaryngology. It is characterized by its role as a cholinergic agonist, meaning it mimics the action of acetylcholine to induce secretions and constrict the pupil.

In a clinical setting, the word is almost exclusively used in the context of treating glaucoma or xerostomia (dry mouth). Because it is a chemical compound and a medication, it is treated as an uncountable mass noun in medical discourse, referring to the substance itself rather than individual units of the drug.
