ICS + LABA + LAMA triple inhaler

Beclometasone with formoterol and glycopyrronium

Brand names: Trimbow

Used in: Asthma

This is a single-inhaler triple combination of beclometasone (inhaled corticosteroid), formoterol (long-acting beta-2 agonist) and glycopyrronium (long-acting muscarinic antagonist), used as maintenance therapy in COPD and, in some products, severe asthma not controlled on dual therapy.

Dosing — being independently re-sourced

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

It pairs anti-inflammatory glucocorticoid action with two complementary bronchodilator mechanisms — beta-2 agonism and muscarinic antagonism — to maximise airflow and reduce exacerbations.

Prescribing in practice

  • Most important: reserve for patients inadequately controlled on dual therapy and counsel on the increased pneumonia risk associated with the inhaled corticosteroid component in COPD.
  • Apply antimuscarinic cautions: avoid or use carefully in narrow-angle glaucoma, prostatic hyperplasia and bladder-outflow obstruction.
  • Confirm the patient is not concurrently using a separate LABA or LAMA inhaler.

Monitoring

Monitor COPD or asthma control and exacerbations, watch for pneumonia and anticholinergic effects, and review cardiovascular tolerance.

Counselling the patient

  • Rinse the mouth after each dose to reduce oral thrush.
  • Report worsening breathlessness with fever, eye pain, or difficulty passing urine, and use it daily as prescribed.

Evidence & guidelines

Single-inhaler triple therapy reduces exacerbations versus dual therapy in COPD trials and is reflected in GOLD and NICE guidance.
