Carbachol
A cholinomimetic agent that stimulates both muscarinic and nicotinic receptors, used as eye drops to treat glaucoma by lowering intraocular pressure and as an intraocular agent during eye surgery to produce rapid pupil constriction. It is resistant to breakdown by cholinesterases, giving it a longer duration of action than acetylcholine. Systemic absorption can cause significant parasympathetic side effects.
