Formoterol Fumarate, Budesonide Used For Asthma.

How it works

Budesonide : Budesonide is a glucocorticosteroid which when inhaled has a dose-dependent antiinflammatory action in the airways, resulting in reduced symptoms and fewer exacerbations. Inhaled Budesonide has less severe adverse effects than systemic corticosteroids. The exact mechanism responsible for the anti-inflammatory effect of glucocorticosteroids is unknown.Formoterol : Formoterol is a selective ß2 adrenoceptor agonist which when inhaled results in rapid and long-acting relaxation of bronchial smooth muscle in patients with reversible airways obstruction. The bronchodilating effect is dose dependent, with an onset of effect within 1-3 minutes. The duration of effect is at least 12 hours after a single dose.
