What is the difference between sympathomimetics and parasympatholytics?

Answer 1

Sympathomimetics are drugs that mimic the effects of the sympathetic nervous system, typically increasing heart rate, dilating airways, and enhancing alertness by stimulating adrenergic receptors. In contrast, parasympatholytics inhibit the actions of the parasympathetic nervous system, leading to effects such as decreased salivation, increased heart rate, and relaxation of smooth muscles by blocking acetylcholine receptors. Essentially, sympathomimetics enhance sympathetic responses, while parasympatholytics suppress parasympathetic effects.
