Combined drug. Codeine - antitussive drug of central action; alkaloid of the phenanthrene series. The opioid receptor agonist, reduces the excitability of the cough center. In recommended therapeutic doses does not cause depression of the respiratory center, does not disrupt the function of ciliated epithelium and does not reduce bronchial secretion, enhances the action of analgesics, hypnotics and sedatives. Activation of opioid receptors in the intestine causes relaxation of smooth muscles, decreased peristalsis and spasm of all sphincters.
Terpinhydrate enhances the secretion of bronchial glands, has an expectorant effect.
Sodium bicarbonate shifts the pH of the bronchial mucus to the alkaline side, reduces the viscosity of the sputum, to some extent also stimulates the motor function of the ciliated epithelium and bronchioles.
Terpinkod ® weakens the cough reflex and promotes the excretion of mucus from the respiratory tract during coughing. The maximum action occurs 30-60 minutes after ingestion and lasts for 2-6 hours.
