Budesonide Respiratory Pharmacology Guide
The complete learning guide for class, mechanism, indications, adverse effects, kinetics, exam traps, and NBRC-style respiratory pharmacology.
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.
