NCIt definition : A secretolytic, with mucolytic activity. Upon administration, bromhexine increases
lysosomal activity and enhances hydrolysis of acid mucopolysaccharide polymers in
the respiratory tract. This increases the production of serous mucus in the respiratory
tract, which makes the phlegm thinner and decreases mucus viscosity. This contributes
to its secretomotoric effect, and allows the cilia to more easily transport the phlegm
out of the lungs. This clears mucus from the respiratory tract and may aid in the
treatment of respiratory disorders associated with abnormal viscid mucus, excessive
mucus secretion and impaired mucus transport.;
