Mechanism
How Budesonide works
Anti-inflammatory corticosteroid that suppresses cytokine production, reduces eosinophilic inflammation, decreases airway edema, and reduces airway hyperresponsiveness.

Budesonide Respiratory Pharmacology Guide
Class, mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-style study pearls.
Budesonide is an inhaled corticosteroid used primarily for long-term control of asthma and selected COPD patients. Its primary benefit comes from reducing airway inflammation rather than causing bronchodilation. Patients should rinse their mouths after use to reduce the risk of oral candidiasis.
