Cholinergic agonists are used to treat dry mouth in certain conditions and to improve near vision in presbyopia. These medications work by stimulating the parasympathetic nervous system, which increases saliva production, reduces eye pressure, and improves focus for close-up tasks. Cholinergic agonists come in different forms, including oral tablets and eye drops. Examples include pilocarpine (Salagen), cevimeline (Evoxac), and pilocarpine eye drops (Vuity). Your prescriber can help you choose the form that best fits your needs.
