CHOLINERGIC DRUGS Meaning and
Definition
-
Cholinergic drugs, also known as cholinergic agonists or parasympathomimetic drugs, are medications that mimic or enhance the action of the neurotransmitter acetylcholine at the cholinergic receptors in the body. Acetylcholine is involved in the regulation and control of various bodily functions, including muscle movement, cognition, memory, and autonomic nervous system activity.
Cholinergic drugs work by binding to and activating the cholinergic receptors, which are found throughout the central nervous system, peripheral nervous system, and neuromuscular junctions. By stimulating these receptors, cholinergic drugs can increase the release or action of acetylcholine, leading to various physiological responses.
These drugs are commonly used to manage conditions such as Alzheimer's disease, myasthenia gravis, glaucoma, urinary retention, and certain gastrointestinal disorders. In Alzheimer's disease, cholinergic drugs are used to improve memory and cognitive function by compensating for the loss of acetylcholine-producing neurons in the brain. They may also help increase muscle strength and improve neuromuscular transmission in myasthenia gravis.
However, cholinergic drugs may also have side effects due to their broad cholinergic effects. These can include increased salivation, sweating, gastrointestinal disturbances (such as nausea, vomiting, and diarrhea), decreased heart rate, bronchoconstriction, and miosis (contraction of the pupil). It is important to note that cholinergic drugs should be used with caution and under the supervision of a healthcare professional, as they can have significant systemic effects on various organ systems.

Etymology of CHOLINERGIC DRUGS
The word "Cholinergic" comes from the combination of "choline" and "-ergic".
"Choline" refers to a compound that is vital for the synthesis of acetylcholine, which is a neurotransmitter that plays a crucial role in the central and peripheral nervous systems. Choline is derived from the Greek word "cholē", meaning "bile", as it was first isolated from bile.
The suffix "-ergic" derives from the Greek word "ergon", meaning "work" or "action". In pharmacology, "-ergic" is used to indicate substances or drugs that affect or stimulate a specific receptor or system in the body.
Therefore, "cholinergic drugs" refers to drugs that work on or interact with cholinergic receptors, promoting the actions of acetylcholine and affecting various bodily functions.
