Ipratropium with salbutamol
Brand names: Combivent, Ipramol Steri-Neb
A combination short-acting bronchodilator delivering the antimuscarinic ipratropium with the beta-2 agonist salbutamol, used for COPD and acute bronchospasm. Combining the two classes gives additive bronchodilation from a single preparation.
Adult dose
Dose auto-extracted from UK Summary of Product Characteristics (SPC) via the eMC — not yet clinician-verified. Always confirm against the product SmPC and your local formulary before prescribing.
Contraindications
- Hypertrophic obstructive cardiomyopathy (§4.3)
- Tachyarrhythmia (§4.3)
- History of hypersensitivity to ipratropium bromide, salbutamol sulfate, or to atropine or its derivatives (§4.3)
Side effects
- Headache, throat irritation and cough — among the most frequent side effects reported in clinical trials (uncommon in the tabulated list)
- Dry mouth, nausea and gastrointestinal motility disorders including constipation, diarrhoea and vomiting
- Dizziness, tremor and nervousness (uncommon); sleep disturbances (rare)
- Palpitations and tachycardia (uncommon); arrhythmia, atrial fibrillation, supraventricular tachycardia and myocardial ischaemia (rare)
- Ocular complications when the solution or mist enters the eye — mydriasis, blurred vision, narrow-angle glaucoma, eye pain, raised intraocular pressure, corneal oedema (rare); also hypokalaemia, paradoxical bronchospasm, urticaria, angioedema and anaphylactic reaction (rare)
Interactions
- Xanthine derivatives, steroids and diuretics — potentially serious hypokalaemia may result from beta2-agonist therapy and this effect may be potentiated by concomitant treatment with these agents; particular caution in severe airway obstruction (§4.4; §4.5 was not retrieved in this bundle)
- Digoxin — hypoxia may aggravate the effects of hypokalaemia on cardiac rhythm, especially in patients receiving digoxin; monitoring of serum potassium is recommended (§4.4)
Clinical monograph
How it works
Salbutamol stimulates beta-2 receptors to relax airway smooth muscle for rapid bronchodilation, while ipratropium blocks muscarinic receptors to reduce cholinergic bronchoconstriction, producing complementary effects.
Prescribing in practice
- When nebulised, shield the eyes from the mist because the ipratropium component can trigger acute angle-closure glaucoma if it contacts the eyes.
- Use cautiously in cardiovascular disease and arrhythmia given salbutamol's cardiac effects, and in prostatic or bladder outflow obstruction given the antimuscarinic component.
- Salbutamol can lower serum potassium, so caution is needed with concurrent hypokalaemia, particularly during acute severe attacks.
Monitoring
Monitor respiratory response, heart rate, tremor and, in acute or high-dose use, serum potassium, while watching for any visual symptoms during nebulisation.
Counselling the patient
- Keep the nebulised mist away from your eyes and report eye pain or blurred vision.
- Mild tremor or a faster heartbeat can occur and usually settles; seek help if symptoms persist or worsen.
Evidence & guidelines
Combining a short-acting antimuscarinic with a short-acting beta-2 agonist is well established in UK practice for COPD and acute airflow obstruction.
