Inhaled drug treatment of COPDoutcomes
Reduce
symptoms
Improve quality of life
Reduce exacerbations
Reduce
deterioration in lung function
Reduce
mortality
Reducing symptoms
Most drugs improve symptoms
Assess & record response to treatment–MRC
score, ability to do activities of daily living,
exercise capacity
Review diagnosis
Inhaler technique
Trial of therapy- if it doesn’t work don’t be afraid
to stop it
Reducing exacerbations
LAMAs & LABAs
POET-COPD trial 2011
Tiotropum vs Salmeterol RCT 7376 patients
time to first exacerbation greater with tiotropium
187 days vs 145 days
•
•
•
patients continued treatment with ICS throughout study
(not NICE)
no info in patients with mild COPD
no info about comparisons with other LABAs
Tiotropium may be more effective than salmeterol in terms of
exacerbations but the evidence is currently unclear
Reducing exacerbations- ICS
Reducing exacerbations
The “frequent exacerbator’’
(more than 2 exacerbations/ year)
Best predictor of having another exacerbation is
frequency of past exacerbations
Effects on lung function
Limited evidence of clinically significant impact
for any drug
Tiotropium UPLIFT trial- clinically important
amount??
Significant person to person variation & no good
predictors of who most likely to deteriorate
Stopping smoking reduces decline
Reducing mortality
SAMAs – increased risk of mortality?
SABAs- no increased risk
LABAs- no evidence of impact
LAMAs- UPLIFT trial showed no impact (but nonsignificant trends towards reducing mortality)
ICS- Cochrane review- no impact
Tiotropium (Spiriva)
Respimat-safety
• significantly increased risk of mortality
• greatest risk seen in patients with more severe
COPD and at a higher daily dose.
• risk was more evident for cardiovascular death
• Excess risk not apparent with Handihaler
• Current MHRA Advice:
Use Respimat with caution in patients with known
cardiac rhythm disorders.
Remind patients on tiotropium not to exceed the
recommended doses
Inhaled corticosteroids- risks
1 extra case of pneumonia for every 47 people
treated with ICS over 1 year
1 person will develop diabetes for every 21
patients treated with ICS over 5 years
1 extra fracture for every 80 people treated with
ICS over 3 years

Inhaled drug treatment –
what are we trying to achieve?
Improving symptoms
Most drugs improve symptoms
Inhaler technique
Record severity and symptoms & assess response to treatment
Trial of inhaler therapy – if it doesn’t work stop it and try another
Reducing exacerbations
Tiotropium and LABAs reduce exacerbations
ICS reduce exacerbations – but side effects
Identify “frequent exacerbators’’ – most likely to benefit from treatment
Review ICS treatment for patients with mild- moderate disease without
exacerbations
Before starting ICS consider potential benefits treatment and risks of
harm for individual patient

similar efficacy to tiotropium
no robust evidence of any advantage over tiotropium or other longacting bronchodilators
no long term data on effectiveness or safety
APC advice: as an option for new patients, do not switch

Mucolytic therapy
Consider in people with a chronic productive cough and continue
use only if symptoms improve.
Mucolytics do not prevent exacerbations. Many patients end up
on long-term mucolytics after starting during an acute
exacerbation. Stop mucolytics routinely after an exacerbation and
reassess before re-starting.
Carbocisteine capsules or oral liquid: 750mg three times a day for 4
weeks (capsules 375mg: Liquid 250mg/5mls)
If no benefit after 4 weeks- stop treatment. If beneficial continue
with 750mg twice a day.
Treatment of COPD exacerbations
Increase frequency of bronchodilator use
Prednisolone 30mg once daily for 7-14 days
Antibiotics 5-7 days: See Worcestershire Guidelines for Primary
Care Antimcirobial Prescribing
1st line- amoxicillin 500mg tds or doxycycline 200mg stat then
100mg daily.
2nd line- clarithromycin 500mg bd
3rd line - co-amoxiclav 625 mg tds If resistance risk factors (co-morbid
disease, severe COPD, frequent exacerbations, antibiotics in last 3
months)
