Corticosteroids
Corticosteroids are medications commonly used by people with
asthma. They work by reducing airway inflammation. They're
known as controller medications (also called preventive or
maintenance medications) because they control the condition overall
and prevent the symptoms from developing. Controller medications
are slow acting, meaning they can take days or even weeks to begin
working. Because they can't provide immediate relief of
symptoms, corticosteroids shouldn't be used when an effect is
needed quickly. This requires faster-acting medications (known as
rescue medications) that can work on the spot.
