Relieves heartburn Frequent heartburn can significantly impair the quality of life of those affected. It is painful and usually lasts for several days, putting a strain on both body and mind. Therefore, it is important to get the symptoms under control. Heartburn, especially at night, disrupts restful sleep and can thus impair daytime performance. PANTOZOL Control tackles the problem directly at its root – in the stomach. The active ingredient pantoprazole inhibits the acid production of the proton pumps. The amount of acid is reduced, and symptoms are relieved both day and night.
