How does it work?
Intal fisonair and spincaps contain the active ingredient sodium cromoglicate (previously spelt cromoglycate in the UK). Sodium cromoglicate is a type of anti-inflammatory medicine that is not a corticosteroid. It prevents tissues becoming inflamed when an allergic reaction occurs.
It is not fully understood how sodium cromoglicate prevents inflammation, but it is thought to work by preventing the release of inflammatory chemicals from cells called mast cells.
Mast cells are cells in the immune system that become sensitised in response to foreign particles, or allergens. When this happens, they release chemicals, including histamine, that go on to cause inflammation as part of the bodys allergic response.
Allergic inflammation in the lungs is one of the causes of asthma. It causes mucus production and narrows the airways, making it difficult to breathe. As sodium cromoglicate reduces the inflammation in the lungs, it makes it easier to breathe and helps prevent asthma attacks. It should be used regularly, even when you have no asthmatic symptoms, to reduce the inflammation in the lungs.
Sodium cromoglicate can also be useful for preventing shortness of breath caused by exercise. You should check with your doctor before using it for this purpose though, as if exercise brings on wheezing or shortness of breath it may mean that your asthma is getting worse or is not very well controlled. If so, your doctor may need to prescribe you another medicine.
Sodium cromoglicate is taken by inhalation. Inhaling the medicine allows it to act directly in the lungs where it is needed most. It also reduces the potential for side effects occurring in other parts of the body, as the amount absorbed into the blood through the lungs is lower than if it is taken by mouth.
Intal fisonair is an inhaler that is connected to a plastic chamber called a spacer device. The dose from the inhaler is sprayed into the spacer, from where it can be inhaled without needing to coordinate breathing and pushing down the inhaler canister.
Intal spincaps are capsules containing sodium cromoglicate that are used in an inhaler device called a spinhaler. The spinhaler pierces the capsule and you then inhale the powder through the spinhaler. The capsules should not be taken by mouth, as they are not effective this way.
What is it used for?
-
Asthma
Warning!
- This medicine is known as a preventer and it should be taken regularly to prevent asthma attacks. It should not be used to relieve an asthma attack, as it will not work for this purpose. An asthma attack needs to be treated with a medicine that quickly opens the airways, such as salbutamol or terbutaline. These are known as relievers, and you should make sure you carry your reliever inhaler with you at all times to relieve an asthma attack if it happens.
