Symbicort turbohaler is made up of two active ingredients: budesonide, a synthetic corticosteroid used to decrease inflammation in the lungs, and formoterol fumarate, a medicine called a long acting beta 2 against or bronchodilator, as it relaxes the muscles in the lungs allowing the airways to open.
People suffering from asthma, or another chronic obstructive airways disease like chronic bronchitis, have difficulties in breathing because the airways in their lungs tighten due to accumulation of mucus produced by the constant inflammation of the passageways.
The Symbicort inhaler works by decreasing the inflammation and therefore halting the production of mucus, and then relaxing the airways to enable easier breathing. It remains in the organism for the next 12 hours. Because it is inhaled and it reduces any possible side effects to other parts of the body and the amount absorbed into the bloodstream is very low.
Symbicort does not need coordinated breathing and pressing of the canister, but rather only breathing in from the inhaler and the medicine will be absorbed by the lungs. The only important thing is to breathe in forcefully and deeply to inhale most of the medicine.
