Comparison: SABA vs LABA

🚀 SABA
Short-Acting Beta-Agonists

Onset: Rapid (within 5 minutes)

🛡️ LABA
Long-Acting Beta-Agonists

Onset: Moderate (15–30 minutes, varies by drug)
Duration: 12 hours or longer
Main Use: Maintenance/control of chronic asthma or COPD
Examples: Salmeterol, Formoterol, Vilanterol, Indacaterol
Role in Asthma/COPD: Added to inhaled corticosteroids for long-term control
Key Feature: NOT for acute relief, never used as rescue medication
Side Effects: Similar to SABA but generally less intense due to slower onset
Warning: Should NOT be used as monotherapy in asthma (increases risk of severe exacerbations); always combine with steroids
