  • Applications

    Pilocarpine Hydrochloride (CAS 54-71-7) is used primarily as an active pharmaceutical ingredient in ophthalmic formulations for glaucoma and ocular hypertension, where it acts as a miotic to constrict the pupil and reduce intraocular pressure; it is also formulated systemically to stimulate salivary secretion in xerostomia. It serves as a pharmacological stimulant in diagnostic contexts such as sweat testing via pilocarpine iontophoresis for cystic fibrosis, and is employed in pharmacology research as a muscarinic receptor agonist to study parasympathetic function. In pharmaceutical manufacturing, Pilocarpine Hydrochloride functions as an API for glaucoma- and dry mouth-related products and can be used as a reference reagent in related alkaloid synthesis.
