No, bethanechol is not used to treat glaucoma; in fact, it can be contraindicated in certain forms of the condition. While it is a muscarinic agonist—a class of drugs that includes some glaucoma medications—bethanechol's effects primarily target the smooth muscle of the bladder and gastrointestinal tract, not the drainage pathways of the eye.

According to prescribing information, oral pilocarpine can cause side effects related to increased parasympathetic activity, including vasodilation. This article explores the pharmacological basis for why pilocarpine causes vasodilation, examining the distinct effects of systemic versus topical administration.

The human body's parasympathetic nervous system controls numerous involuntary functions, from digestion to urination, primarily using acetylcholine as its neurotransmitter [1.2.1, 1.2.2]. The central question for many is, do cholinergics constrict tissues, and what are the widespread implications of this action?

Miotics are a class of medication specifically designed to constrict the pupil. A prominent example is pilocarpine, the primary drug used for the construction of the pupil in various medical treatments.

Miotics, or cholinergic agonists, have been used in eye care for over a century, with pilocarpine being the most widely recognized topical example. In modern ophthalmology, two primary miotic drugs, pilocarpine and carbachol, are used to constrict pupils and increase fluid drainage to lower intraocular pressure, notably in the treatment of certain types of glaucoma.

Miotics are parasympathomimetic drugs primarily used to lower intraocular pressure in glaucoma by increasing the outflow of aqueous humor [1.6.2]. When researching 'What are the side effects of miotics quizlet', it's crucial to understand both the eye-related (local) and body-wide (systemic) adverse effects.

Miotics, used to treat conditions like glaucoma, are known to cause a range of adverse effects that must be carefully managed. Understanding **what are the side effects of miotics?** is a crucial aspect of patient care to ensure safety and adherence to therapy.

Used for over a century in ophthalmology, miotic agents have historically served as a key treatment for glaucoma and other ocular conditions. Understanding **what is the mechanism of action of miotics** involves exploring how these drugs stimulate the parasympathetic nervous system to cause pupil constriction and manage intraocular pressure.

First used in eye care for over a century, miotic drugs cause the pupil to constrict, a process known as miosis, by affecting the eye's muscles. This pharmacological action, which can either stimulate the parasympathetic pathway or inhibit the sympathetic pathway, is leveraged to treat various eye conditions. A diverse range of miotic drug examples exists, each with a unique mechanism and application.

Dry mouth, or xerostomia, affects approximately 20% of the adult population. For those seeking relief, understanding **what drugs increase saliva production** is crucial for managing symptoms and preventing further oral health complications.
