Beta Blockers and Chronic Obstructive Pulmonary Disease (COPD): Sum of Evidence.

Approximately half a century has passed since the discovery of beta-blockers. Then, their prime therapeutic purpose was to treat angina and cardiac arrhythmias; nowadays, beta-blockers' usage and effectiveness are extended to treat other cardiovascular diseases, such as hypertension, congestive heart failure, and coronary artery disease. Safety concerns were raised about beta- blockers and their use for chronic obstructive pulmonary disease (COPD) patients with concurrent cardiovascular disease. After thorough research of the literature, this review summarizes the evidence proving that beta-blockers not only might be well tolerated in COPD patients, but they might also have a beneficial effect in this group of patients.
