Dembrexine is a mucolytic agent which reduces the viscosity of respiratory mucus. It improves movement of mucus in small airways. Dembrexine increases secretion of the serous cells in the glands of the nasal, tracheal and bronchial cells and in type II alveolar cells. It also possesses an anti-tussive effect. Dembrexine is used in the treatment of respiratory disease in horses. All respiratory infections with increased secretions. Acute, sub-acute bronchitis. Chronic respiratory disease. Infection of the upper airways.
