The effect of Ambroxol on bleomycin-induced changes in phospholipid composition of rat lung surfactant

The influence of Ambroxol on bleomycin-induced changes in lung surfactant phospholipid composition in rats was examined. Bleomycin alone (intratracheally 10 mg/kg, single dose) produces a significant fall in phosphatidylcholine (especially in disaturated species) and phosphatidylglicerol content in both lavage and postlavaged lung tissues surfactants. Ambroxol (8 days, 2 mg/kg s.c. per day) normalizes these changes. Thus, Ambroxol has an salutary effect on bleomycin-induced changes in lung surfactant phospholipids.
