Contrary to a simple classification, the effect of cholinergic drugs on blood vessels is not uniform and can be paradoxical, depending on the state of the vascular endothelium. The intricate interplay between acetylcholine, endothelial health, and different receptor subtypes determines whether cholinergic drugs cause vasoconstriction or vasodilation.

With millions of people affected, glaucoma is a serious eye condition often managed by controlling intraocular pressure (IOP) to prevent vision loss. Cholinergic drugs help with glaucoma by targeting the eye's natural drainage system to increase fluid outflow and reduce this pressure.

With a history in eye care spanning over 100 years, miotic drugs have long been an essential tool for managing various ocular conditions. This guide will answer the question, "What drugs are miotics?" by exploring their mechanisms, common uses, classifications, and important safety considerations.

Pinpoint pupils, medically known as miosis, are pupils that shrink to a diameter of less than two millimeters [1.6.4]. Answering 'what drug would cause pinpoint pupils?' is critical, as this symptom is a classic sign of opioid overdose, a serious medical emergency [1.2.1].

Opioids are one of the most common drug classes known to cause constricted pupils (miosis) by affecting the central nervous system. Understanding which medication causes the pupil to constrict is crucial for both medical professionals and patients to identify potential drug effects and overdoses.

In ophthalmology, pupillary control is critical, with cholinergic agonists being used to treat conditions like glaucoma by lowering pressure in the eye [1.2.1]. Contrary to the query, the fundamental question 'Do cholinergic drugs cause mydriasis?' has a definitive answer: no, they cause the opposite effect, miosis [1.2.4].

The constriction of the pupil, a process known as miosis, is a vital physiological response primarily controlled by the parasympathetic nervous system. Many medications, referred to as miotics, can induce this effect by mimicking or enhancing the action of the neurotransmitter acetylcholine. This article clarifies which of the following causes the pupil to constrict (miotics).

According to a review of psychotropic agents, excessive drooling, or sialorrhea, is a common and distressing side effect for many psychiatric patients, with clozapine being the most commonly implicated antipsychotic. This article explores **what medications can cause drooling** and the underlying pharmacological mechanisms.

The human body's 'rest and digest' functions are primarily controlled by the parasympathetic nervous system, with acetylcholine being its chief neurotransmitter. Cholinergic drugs are a class of medications that target this system by enhancing or mimicking the action of acetylcholine. This article explains what these drugs are, their mechanisms, and their important therapeutic applications.

Acetylcholine plays a crucial role in memory, learning, and muscle contraction, and its deficiency is a hallmark of conditions like Alzheimer's disease. A variety of drugs are designed to increase acetylcholine levels or mimic its effects to treat cognitive and neuromuscular disorders.
