Active Ingredient
Description

Glycopyrronium is an inhaled long-acting muscarinic receptor antagonist (anticholinergic) for once-daily maintenance bronchodilator treatment of COPD. Glycopyrronium works by blocking the bronchoconstrictor action of acetylcholine on airway smooth muscle cells, thereby dilating the airways.

Otilonium is endowed with a marked spasmolytic action on the smooth muscle of the digestive tract.

Prifinium is an anticholinergic preferably acting at muscarinic receptors in the gastrointestinal tract. It corrects chlorhydropeptique hypersecretion, gastrin, pancreatic.

Propantheline inhibits parasympathetic activity by blocking the action of the neurohormone, acetylcholine, on the neuroeffector cell. This blocking action of propantheline is instrumental in reducing gastric acid secretion and gastrointestinal motor activity.
