Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
A feasibility study to assess whether cardio-selective beta-blockers can be started in patients with stable COPD. If patients can tolerate the drug, this will inform future randomised, placebo-controlled trial.
Oral bisoprolol will be started at a dose of 1.25mg daily, increased to 2.5mg daily after 2 weeks and to a target dose of 5mg daily after a further 4 weeks if tolerated. This dose will be maintained for a further 6 weeks.
Compliance will not be objectively monitored

Outcomes
Primary outcome [1] 298700 0
Ability to recruit eligible patients - percent of eligible patients screened who are started on the beta-blocker
Timepoint [1] 298700 0
one year
Primary outcome [2] 298701 0
Proportion of patients who tolerate cardio-selective beta-blockers, judged by the proportion of participants who remain on the beta-blockers at the end of the study (self-report).
Timepoint [2] 298701 0
3 months after starting drug
Secondary outcome [1] 325005 0
Proportion of patients who reach the target dose of 5mg bisoprolol once daily. Assessed by the number of participants who are dispensed the drug and report taking it.
Timepoint [1] 325005 0
3 months after starting drug
Secondary outcome [2] 325006 0
Proportion of patients experiencing beta-blocker related adverse events and description of these adverse events.
All adverse events will be noted: these events will be detected by self-report, clinical notes, third-party reports (e.g. other doctors or coroner) and/or clinical observations at follow-up,
Pulse, blood pressure, spirometry, and ECGs will be done at each follow-up visit to record the cardiovascular and airway effects of the drug.
Timepoint [2] 325006 0
3 months after starting drug
