title: Influence of ambroxol on the bronchopulmonary level of antibiotics.
abstract: Antibiotic levels in bronchopulmonary tissue following oral administration of ampicillin, erythromycin and amoxycillin dosed 50 mg/dg were compared with those obtained by the same treatments n0 mg/dg p.o of trans-4-[(2-amino-3,5-dibromo-benzyl)amino]cyclohexanol (ambroxol, Mucosolvan) in several groups of rats. The addition of ambroxol was correlated with an increase of 234% in the pulmonary average concentration of ampicillin, 27% in that of erythromycin 27% in that of amoxycillin; the statistical evaluation of these differences resulted in less than 0.05 in each case. It may be concluded that ambroxol, through a mechanism still unclear, can increase the antibiotic levels in the lungs of the rat.
