Carbachol
Carbachol (pronounced: car-ba-chol) is a cholinergic drug that mimics the neurotransmitter acetylcholine. It is primarily used in the treatment of glaucoma, but it can also be used to induce miosis (constriction of the pupil) during certain eye surgeries.
Etymology
The term "Carbachol" is derived from "carbamic acid" and "acetylcholine". Carbamic acid is a compound that is used in the production of some types of drugs, and acetylcholine is a neurotransmitter in the body that transmits signals in the nervous system.
Pharmacology
Carbachol is a cholinergic agonist that binds to and activates muscarinic and nicotinic acetylcholine receptors. This action stimulates the parasympathetic nervous system, which is responsible for rest and digest activities. In the eye, this leads to a decrease in intraocular pressure, making it useful in the treatment of glaucoma.
Medical Uses
Carbachol is primarily used in the treatment of glaucoma, a condition that causes increased pressure in the eye and can lead to vision loss. It can also be used to induce miosis, or constriction of the pupil, during certain eye surgeries.
Side Effects
Common side effects of carbachol include blurred vision, eye irritation, and increased salivation or sweating. More serious side effects can include slow heart rate, low blood pressure, and difficulty breathing.
