Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All COPD patients who fulfil the inclusion criteria will be given oral metoprolol (ATC C07A B02) 25mg daily for 21 days.

Patients will be assessed on Day 0, 1 and 21 for any side effects from oral metoprolol as well as the effect of metoprolol on spirometry.

Outcomes
Primary outcome [1] 304036 0
To assess the safety of commencement of metoprolol in patients admitted with exacerbation of COPD with co-existing cardiovascular diseases, as defined by any adverse events,
Known adverse events from beta blocker includes hypotension, bradycardia, and bronchospasm.
Patients will be monitored for possible adverse events on day 0, 1 and 21 by performing spirometry as well as completion of a St George's Respiratory Questionnaire (SGRQ).
Timepoint [1] 304036 0
Baseline, Day 1 and Day 21 post metoprolol commencement.
Secondary outcome [1] 340776 0
To assess the impact of commencement of metoprolol on lung function as measured by post bronchodilator spirometry in patients admitted for exacerbation of COPD.
Timepoint [1] 340776 0
Baseline, Day 1 and Day 21 post commencement of metoprolol.

Summary
Brief summary
Cardiovascular comorbidity is common in patients with COPD. They share cigarette smoking as an important risk factor. However, beta blockers, which are commonly used to treat cardiac diseases, are traditionally avoided in patients with COPD due to the theoretical risk of respiratory adverse events. The aims of this study are:

1. To assess the safety of commencing beta blockers during an acute exacerbation of COPD in individuals with coexistent cardiovascular disease.
2. To assess the impact of commencement of beta blockers on lung function as measure by post bronchodilator spirometry in patients admitted for exacerbation of COPD.

This is a prospective interventional study of individuals admitted with exacerbations of COPD conducted in two metropolitan hospitals in Melbourne. Individuals who are admitted to the Northern and Austin Hospital with acute exacerbations of COPD who have a history of COPD (GOLD Class II – III) and of cardiovascular disease will be invited to participate in the study. When they are considered stable and suitable for participation, the treating team will notify the study coordinator who will consent and enroll the individual in the study.

After signing of the informed consent form, participants who are identified to be ready for discharge the following day will perform spirometry. An initial dose of a cardio-selective beta blocker will be administered and spirometry will be repeated.
Unless an adverse event has occurred, beta blocker administration will continue on the day of discharge, with spirometry repeated. Participants will be reviewed at 21-days post discharge with repeat spirometry. This will be carried out in the Respiratory Outpatient Clinic as is standard practice.
