Do inhaled beta-agonists control cough in acute bronchitis?

Abstract

The value of inhaled β2-agonists in patients with acute bronchitis is unclear and any potential benefit remains unproven. (Two small randomized controlled trials [RCTs] using different agents reached different conclusions.) Beta-agonists may have a role in patients with acute bronchitis who are wheezing.
