Pilocarpine is a muscarinic receptor agonist, specifically targeting the M3 subtype of muscarinic receptors found on the iris sphincter muscle and the ciliary muscle. When activated, these receptors cause muscle contraction, leading to pupil constriction (miosis) and facilitating the outflow of aqueous humor from the eye, respectively. These actions result in a decrease in intraocular…
