Full information about Nitro-Dur

General Information on Nitro-Dur

Nitro-Dur is part of a group of drugs called nitrates or antiaginals. It helps prevent chest pain (angina) arising due to coronary artery disease. However, it does not help in curing the already initiated pain.

When Nitro-Dur enters the body, its main function is to relax the blood vessels by increasing the supply of blood and oxygen, which reduces the heart’s workload. Regular use of Nitro-Dur for a long time helps prevent chest pain.

The medicine can be purchased only with a doctor’s prescription. However, before you buy Nitro-Dur, you must inform your doctor if you have problems related to the heart and blood pressure. Consult your doctor before buying Nitro-Dur if you are pregnant or breastfeeding.

Side effects of Nitro-Dur

Nitro-Dur has a few unwanted side effects. In case any side effects occur, they must be brought to the attention of the doctor. Lightheadedness is the most common side effect of Nitro-Dur. Some of the rare and less common side effects of Nitro-Dur are:
