Beclometasone / Formoterol / Glycopyrronium
Brand names: Trimbow
This is a single-inhaler triple therapy combining beclometasone (inhaled corticosteroid), formoterol (long-acting beta-2 agonist) and glycopyrronium (long-acting muscarinic antagonist), used for maintenance treatment of COPD and, in some products, severe asthma.
ClinCalc Pro is rebuilding its dose data from primary open sources — the manufacturer SmPC (eMC), the WHO Model Formulary and other official references — under clinician review. This drug's structured dose is not yet published here. Confirm all doses against the product SmPC and your local formulary before prescribing.
Clinical monograph
How it works
Beclometasone dampens airway inflammation, formoterol relaxes bronchial smooth muscle via beta-2 receptors, and glycopyrronium produces additional bronchodilation by blocking muscarinic receptors.
Prescribing in practice
- Most important: reserve triple therapy for patients inadequately controlled on dual therapy and review pneumonia risk, as the inhaled corticosteroid component increases pneumonia incidence in COPD.
- Use the antimuscarinic with caution in symptomatic prostatic hyperplasia, bladder-outflow obstruction and narrow-angle glaucoma.
- Ensure the patient is not also taking a separate LABA or LAMA to avoid duplicate long-acting bronchodilator exposure.
Monitoring
Monitor COPD control and exacerbations, watch for pneumonia, and review cardiovascular symptoms and anticholinergic side effects.
Counselling the patient
- Rinse the mouth after each dose to reduce oral thrush.
- Report worsening breathlessness with fever or new urinary difficulty, and use it every day as prescribed.
Evidence & guidelines
Single-inhaler triple therapy is supported by trials showing reduced exacerbations versus dual therapy in COPD and is reflected in GOLD and NICE guidance.
