Angitak spray contains the active ingredient isosorbide dinitrate, which is a type of medicine called a nitrate. It is used to help the heart work more easily.
Isosorbide dinitrate works by being converted in the body to a chemical called nitric oxide. This chemical is made naturally by the body and has the effect of making the veins and arteries relax and widen (dilate). When the blood vessels dilate in this way there is more space inside them and hence less resistance. This makes it easier for the heart to pump blood around the body.
Widening the veins also decreases the volume of blood that returns to the heart with each heartbeat. This makes it easier for the heart to pump that blood out again.
As a result of both these actions, the heart does not need as much energy to pump the blood around the body and therefore needs less oxygen.
Isosorbide dinitrate also widens the arteries within the heart itself, which increases the blood and oxygen supply to the heart muscle.
The pain of angina is caused by too little oxygen reaching the heart when its workload increases, such as during exercise. Isosorbide dinitrate improves the oxygen supply to the heart, as well as decreasing the amount of oxygen that the heart needs by making it easier for the heart to pump blood around the body. It can therefore be used to treat angina.
Angitak spray is sprayed under the tongue. This area of the mouth has a large supply of blood vessels that allows the medicine to be rapidly absorbed. Isosorbide dinitrate taken in this way is used to give rapid relief from the pain of an angina attack. The spray can also be used to prevent an anticipated attack, for example before exercise or physical effort, emotional stress or exposure to cold.
Isosorbide dinitrate is also available as long-acting tablets that are taken regularly each day to help prevent angina attacks. See the factsheets linked at the end of this article for more information.
