A controlled trial of ambroxol in chronic bronchitis

G H Guyatt et al. Chest. 1987 Oct.

Abstract

Ambroxol is a mucolytic agent which is widely used in chronic bronchitis in Europe. We conducted a double-blind randomized controlled trial of ambroxol vs matched placebo in 90 patients with chronic bronchitis and difficulty clearing secretions. It was concluded that there was no advantage to taking ambroxol.
