Hyoscyamine has actions similar to those of atropine, but is more potent in both its central and peripheral effects. Symax® SR inhibits gastrointestinal propulsive motility and decreases gastric acid secretions. This product controls excessive pharyngeal, tracheal, and bronchial secretion. Once absorbed, this product disappears rapidly from the blood and is distributed throughout the entire body.
