Glycopyrrolate (glycopyrrolate) — Uses, Dosage, Side Effects & Safety

Drug class: Anticholinergic (Antimuscarinic) agent

Overview

Glycopyrrolate is a medication used to reduce excessive saliva (drooling), treat peptic ulcers, and as an adjunct in anesthesia to reduce secretions and prevent bradycardia. It is also used in chronic obstructive pulmonary disease (COPD) as an inhaled formulation to help open the airways. Glycopyrrolate works by blocking the action of acetylcholine, a chemical messenger in the body, on muscarinic receptors. This reduces secretions in the mouth, airways, and stomach, and helps relax smooth muscles. Key points for patients: Glycopyrrolate may cause dry mouth, constipation, and blurred vision. It is important to take the medication exactly as prescribed and to inform your healthcare provider about any other medications or medical conditions.
