Which of the following is NOT an effect of Pilocarpine?

Pilocarpine is a muscarinic agonist that primarily stimulates the parasympathetic nervous system, leading to various physiological effects. One of the hallmark actions of pilocarpine is miosis, or constriction of the pupils, which is caused by the contraction of the iris sphincter muscle. Furthermore, pilocarpine enhances salivation by stimulating salivary glands, making it effective for conditions such as dry mouth.

Additionally, it promotes ciliary muscle contraction, which facilitates accommodation for near vision by allowing the lens to become more rounded.

Pupil dilation, on the other hand, is not an effect of pilocarpine. Dilation occurs when sympathetic stimulation occurs, typically through adrenergic agents. Thus, the correct response points out that pupil dilation is not an effect associated with pilocarpine's action, highlighting its selectivity for the parasympathetic action rather than sympathetic responses.
