Symbicort is made by AstraZeneca.
Symbicort contains two different medications:
budesonide and
formoterol. Formoterol is part of a class of drugs called beta-adrenergic receptor agonists, or beta agonists for short. Beta agonists stimulate beta receptors in the body, including those on the muscles around airways. This stimulation causes the muscles to relax, which opens up the airways and allows more air to get into and through the lungs.
The other component of Symbicort is budesonide, an
asthma medication that belongs to a group of drugs called inhaled corticosteroids, or steroids for short. Inhaled steroids go directly into the lungs and help to decrease the inflammation of airways that makes
asthma attacks more likely.
Because Symbicort does not work quickly, it should not be used for treating an asthma attack. Rather, it is used twice a day in order to prevent them.
