Glycopyrrolate is a medication used to reduce saliva, mucus, and other secretions in the respiratory tract, stomach, and intestines. It belongs to a class of drugs called anticholinergics or antimuscarinics.

Glycopyrrolate works by blocking the action of acetylcholine, a neurotransmitter that stimulates glands to produce saliva and mucus. By inhibiting the effects of acetylcholine, glycopyrrolate helps to reduce the production of saliva and mucus, which can be beneficial in various medical conditions.
