Pilocarpine and the Intestines: Effects, Mechanisms, and Side Effects

Pilocarpine is a muscarinic cholinoreceptor agonist with a high affinity for M3 receptors. It is commonly used in the treatment of glaucoma, but it also has effects on the gastrointestinal tract.

Pilocarpine stimulates the muscarinic cholinoreceptors in the intestine, leading to increased secretion of fluids and electrolytes into the lumen. This can result in diarrhea and abdominal pain. In addition, pilocarpine may also increase the tone and motility of the intestine, which can contribute to these effects.

The effects of pilocarpine on the intestine are typically dose-dependent, and they may vary depending on the individual. In general, pilocarpine is not recommended for use in patients with gastrointestinal conditions such as diarrhea or abdominal pain.
