Mechanism
How Symbicort works
Combines inhaled corticosteroid anti-inflammatory activity from budesonide with long-acting beta agonist bronchodilation from formoterol.

Symbicort Respiratory Pharmacology Guide
Class, mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-style study pearls.
Symbicort combines budesonide, an inhaled corticosteroid, with formoterol, a long-acting beta agonist. Budesonide controls airway inflammation while formoterol provides prolonged bronchodilation. Students should recognize Symbicort as an ICS/LABA combination and identify both component medications.
Clinical Pearl
What to remember
Know both ingredients and remember that formoterol is the fast-onset LABA.
