Chronic Obstructive Pulmonary Disease (COPD)
The pathways in this section refer to the GOLD Guidelines. This means that pathways (GOLD A, B, E) are not a stepwise progression, but intended as a guide for initiation of the pharmacological management of COPD according to the individual patient assessment of symptoms and exacerbation risk following the ABE scheme. Following reclassification of GOLD guidelines in 2023, patients historically prescribed monotherapy bronchodilators should be reviewed accordingly.
As part of NHS Scotland’s commitment to greener health care, the environmental impact of inhalers has been taken into account whilst developing the regional formulary. The West of Scotland Formulary encourages prescribers to base the choice of inhaler(s) for COPD on an assessment of correct technique, the preference of the person receiving the treatment, the lowest environmental impact among suitable devices and the presence of an integral dose counter.
A diagnosis of COPD must be made using spirometry. The presence of non-fully reversible airflow limitation (i.e. FEV1/FVC < 0.7 post-bronchodilation) measured by spirometry is mandatory to establish the diagnosis of COPD.

Prescribing Notes:
- Best practice is to prescribe all inhalers by brand name and device type, specifying strength and dose.
- Assessment of a patient’s inhaler technique is required before an inhaler is prescribed as this will determine the choice of product. Information on assessing inhaler technique and counselling on the correct method can be found at the Asthma and Lung UK inhaler technique videos.
- Regularly checking inhaler technique is recommended to ensure patients are still able to use the device prescribed.
- All inhalers have different ‘in use’ expiry, this can lead to unintended wastage. Ensure patients are given adequate advice on effective use of the device. For example, an inhaler with an in-use expiry of 6 weeks: one inhaler lasts 1 month with regular use. If 2 inhalers are prescribed and dispensed and both opened at the same time, they will both expire 6 weeks later, but if opened one at a time they would have lasted 2 months.
- Inhaler-induced cough by MDI may be alleviated by use of a spacer or change of device.
- Not all spacers are compatible with all inhalers; users should seek advice from their local pharmacist regarding the appropriate spacer to be used. Please refer to the RightBreathe website for guidance on compatibility and training material.

Regional formulary chapter launched.
Bronchodilator options for 0 or 1 moderate exacerbations (no hospital admissions) and mMRC 0-1, CAT <10.
SABA Dry Powder Inhaler – Easyhaler Salbutamol or Metered Dose Inhaler – Salbutamol.
LAMA Soft Mist Inhaler – Spiriva Respimat. Patients only need the full device prescribed twice a year, with refill cartridges prescribed in the intervening time to minimise waste.
Prescribing Notes:
- There is virtually no difference in efficacy between salbutamol and terbutaline; currently salbutamol is less expensive and available in a wider range of devices.

LAMA/LABA (Long-Acting Muscarinic Antagonist/Long Acting Beta2 Agonist) options for 0 or 1 moderate exacerbations (no hospital admissions) and mMRC ≥ 2, CAT ≥10.
LAMA/LABA Dry Powder Inhaler – Anoro Ellipta.
LAMA/LABA Soft Mist Inhaler – Spiolto Respimat.
When the patient has used an inhaler with 6 cartridges, prescribe a new Spiolto Respimat pack containing an inhaler. Do not use the Respimat re-usable inhaler for more than one year, after having inserted the first cartridge.
LAMA/LABA Metered Dose Inhaler – Bevespi Aerosphere.
Prescribing Notes:
- Before prescribing a Respimat device please ensure patient can load and activate the device.
- For patients with persistent breathlessness or exercise limitation on bronchodilator monotherapy, the use of LAMA/LABA is recommended.
- Following GOLD guideline reclassification, it is recommended that patients on historical monotherapy should be reviewed as appropriate.

LAMA/LABA (Long-Acting Muscarinic Antagonist/Long Acting Beta2 Agonist) options for ≥2 moderate exacerbations (or ≥1 leading to hospital admission) in the past year.
LAMA/LABA Dry Powder Inhaler – Anoro Ellipta.
LAMA/LABA Soft Mist Inhaler – Spiolto Respimat.
When the patient has used an inhaler with 6 cartridges, prescribe a new Spiolto Respimat pack containing an inhaler. Do not use the Respimat re-usable inhaler for more than one year, after having inserted the first cartridge.
LAMA/LABA Metered dose Inhaler – Bevespi Aerosphere.
LABA/LAMA/ICS (Long Acting Beta2 Agonist/ Long-Acting Muscarinic Antagonist/ Inhaled Corticosteroid Combination) options for ≥2 moderate exacerbations (or ≥1 leading to hospital admission) if blood eosinophils ≥300 cells/microlitre.
LABA/LAMA/ICS Dry Powder Inhaler – Trelegy Ellipta.
LABA/LAMA/ICS Metered Dose Inhaler – Trixeo Aerosphere.
LABA/LAMA/ICS Dry Powder Inhaler – Trimbow NEXThaler.
Prescribing Notes:
- Before prescribing a Respimat device please ensure patient can load and activate the device.
- Combination products can be a cost-effective alternative to the individual products and are more convenient to use. Choice will depend on the selected inhaled steroid and inhaler technique.
- If patients with COPD have concomitant asthma, they should be treated like patients with asthma. Refer to Asthma pathways. Under these circumstances the use of an ICS is mandatory.
- Blood eosinophil counts may identify patients with a greater likelihood of a beneficial response to ICS. For patients who develop exacerbations with a blood eosinophil count ≥ 300 cells/µL, escalation to LABA+LAMA+ICS may be considered.
- Withdrawing ICS should be considered if pneumonia or other considerable side-effects develop.
- See the Healthcare Improvement Scotland website for details around the use of a Steroid Emergency Card.

Prescribing Notes:
- Prescribing of azithromycin should be on the advice of a respiratory specialist, following sensitivities and investigations in secondary care.
- The use of azithromycin is for both its antibiotic and anti-inflammatory properties.

Prescribing Notes:
- A 4-week trial of a mucolytic agent should be considered in COPD patients chronically troubled by sputum production. Only continue if symptoms improve.
- Ensure the most cost-effective brand of acetylcisteine is chosen in line with individual health Board preference.
- The dose of carbocisteine can be reduced as the condition improves.

Prescribing Notes:
- Nebulisers are not currently prescribable in general practice, however the nebules used within them are. Patients should be referred for respiratory assessment and if suitable they will be leased a machine. A spacer should be tried before considering a nebuliser.

Nebulisers should only be used in patients with an FEV1<50% and on maximum inhaled therapy under care of a respiratory specialist.
Prescribing Notes:
- Nebulisers are not currently prescribable in general practice however the nebules used within them are. Patients should be referred for respiratory assessment and if suitable they will be leased a machine. A spacer should be tried before considering a nebuliser.
- All nebulisers should be serviced regularly. However, difficulties are often encountered in the servicing of privately owned nebulisers. Patients should be discouraged from buying a nebuliser.

Prescribing Notes:
- Not all spacers are compatible with all inhalers; users should seek advice from their local pharmacist regarding the appropriate spacer to be used. Please refer to the RightBreathe website for guidance on compatibility and training material.
- The Asthma+Lung UK website provides guidance on different breathing techniques with a spacer – the single breath and hold technique, or the tidal/multiple breath technique.
- Spacers should be cleaned no more than weekly, with water and washing-up liquid, or put in a dishwasher, and allowed to air dry. More frequent cleaning affects their performance due to build-up of static.
- AeroChamber Plus Flow-Vu and Volumatic should be replaced every 12 months following regular use.
