Background: Acetylcysteine and carbocysteine are the most commonly prescribed mucolytic drugs in many European countries. To our knowledge, no systematic review has been published on their efficacy and safety for acute upper and lower respiratory tract infections (ARTIs) in children without chronic broncho-pulmonary disease.
Objectives: The objective was to assess the efficacy and safety and to establish a benefit-risk ratio of acetylcysteine and carbocysteine as symptomatic treatments for ARTIs in children without chronic broncho-pulmonary disease.
