parasympathomimetic drugs

Parasympathomimetic drugs are medications that mimic the effects of the parasympathetic nervous system, which is responsible for conserving energy and promoting relaxation in the body. These drugs enhance activities like slowing the heart rate, increasing digestive secretions, and contracting smooth muscles, such as those in the eyes and airways. They are often used to treat conditions like dry mouth, glaucoma, or urinary retention. Essentially, they imitate natural signals that promote rest and maintenance functions, helping restore balance when these processes are impaired.
