Indications ▼
Acute bronchospasm in asthma
Exacerbations of COPD
Patients needing combined bronchodilator therapy for rapid relief
Mechanism & Pharmacokinetics ▼
Mechanism: Salbutamol is a selective β2-agonist causing bronchodilation by relaxing bronchial smooth muscle. Ipratropium is an anticholinergic agent that blocks muscarinic receptors, reducing bronchoconstriction and mucus secretion. Combined use provides synergistic bronchodilation.
Pharmacokinetics: Inhaled salbutamol has rapid onset (5–15 min), metabolized in liver, excreted mainly in urine. Ipratropium onset 15–30 min, peak effect 1–2 hours, minimal systemic absorption; mainly excreted unchanged in urine.
Dosage & Administration ▼
| Formulation | Dose | Frequency |
|---|---|---|
| MDI | 2 inhalations (100 µg + 20 µg each) | Every 4–6 hours as needed |
| Nebulizer solution | 2.5 mg Salbutamol + 0.5 mg Ipratropium in 2–5 mL saline | Every 4–6 hours as needed |
Note: Use inhalation route for rapid relief. Adjust dose based on age, response, and severity.

Excreted in breast milk; monitor infant if used during lactation
Clinical / Research Summary ▼
Clinical Role: Combined bronchodilator for rapid relief of bronchospasm in asthma and COPD, particularly in exacerbations.
Advantage: Synergistic effect provides superior bronchodilation compared to either agent alone.
Limitation: Does not control underlying inflammation; frequent use requires controller therapy adjustment.
Monitoring: Symptom relief, heart rate, urinary retention in high-risk patients.
