Action
Description: Bromhexine is a mucolytic agent that acts on the mucus gland in the respiratory tract to change the structure of bronchial secretion. It enhances the transport of mucus by reducing its viscosity and increases cilia activity resulting in enhanced mucociliary clearance. This secretolytic and secretomotor effect in the bronchial tract facilitates expectoration and relieves cough.

Distribution: Crosses blood brain-barrier; placenta (small amounts). Plasma protein binding: 95% (unchanged drug).
Metabolism: Almost completely metabolised to a variety of hydroxylated metabolites, including ambroxol and dibromanthranilic acid. Undergoes extensive hepatic first-pass metabolism.
Excretion: Via urine (approx 97.4 ± 1.9%; <1% as unchanged drug). Terminal elimination half-life: 6.6-31.4 hours (single dose).
