1. What Diltiazem Retard Stada is and what it is used for

Diltiazem Retard Stada belongs to a group of medicines called calcium antagonists. Diltiazem Retard Stada is a medicine that reduces the heart rate. It has a vasodilating effect. This improves circulation from the heart and prevents chest pain due to lack of oxygen in the heart muscle. It also improves circulation in the heart vessels and reduces high blood pressure. This effect lasts 24 hours and therefore one capsule per day is sufficient.

Diltiazem Retard Stada is used for the treatment of chest pain (stable angina pectoris).

Diltiazem Retard Stada is used for the treatment of mild to moderate high blood pressure.

Chest pain (stable angina pectoris)

Chest pain is a feeling of pressure in the chest. The pain can radiate to one or both arms, neck, jaw, or back. Chest pain can be associated with angina, oppression, or a feeling of alarm. It can mainly occur during periods of exertion or agitation. Once you calm down, the symptoms disappear quickly. A "attack" of chest pain usually lasts a few minutes, but sometimes it can last longer.

High blood pressure is usually not noticeable. The result of the treatment of high blood pressure can only be evaluated by measures taken by your doctor.
