NCIt definition : The hydrochloride salt form of bromhexine, 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.;
