Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Feasibility of starting a cardioselective beta-blocker (metoprolol) in patients with an exacerbation of COPD. Participants will be given a test dose of 12.5 mg standard oral metoprolol in hospital. If this is tolerated, they will be commenced on a low dose of 23.75mg controlled-release metoprolol on daily. The dose will be increased after two weeks to 47.5mg daily and after a further 4 weeks to 95mg daily if tolerated. The duration of treatment will be 3 months.

Outcomes
Primary outcome [1] 292985 0
Whether participants tolerate beta-blocker treatment according to patients and clinician judgement. Patients may be able to tolerate a lower dose of beta-blocker, but not the target dose of 95mg. The primary outcome is whether beta-blocker therapy is stopped completely.
Timepoint [1] 292985 0
3 months
Secondary outcome [1] 310083 0
Adverse effects. These include acute bronchospasm, postural dizziness, falls, severe bradycardia, heart block. Symptoms will be recorded, ECG, spirometry, blood pressure and pulse will be measured at each clinic assessment prior to each dose increase.

Summary
Brief summary
Beta-blocker treatment is known to improve survival from several cardiac diseases. Unfortunately, beta-blockers are usually avoided in patients with chronic obstructive pulmonary disease (COPD) because of concerns that they may make airflow obstruction worse. Therefore patients with COPD are often deprived of the benefits of beta-blockers even though they have a very high risk of cardiac problems. Recent evidence suggests that beta-blockers may be safe and effective in lung disease but there have been no clinical studies to confirm this. This feasibility study will assess the safety and tolerability of metoprolol, a cardio-selective beta-blocker, in patients with exacerbations of COPD to determine whether a randomised controlled trial of beta-blockers should be conducted. The randomised study would provide a definitive answer on whether beta-blockers are safe and effective in patients with chronic obstructive pulmonary disease.
