Action
Description: Ambroxol is a mucolytic agent that increases respiratory tract secretion by enhancing the production of pulmonary surfactants and stimulating the ciliary activity. This activity results in the improvement of mucociliary clearance and enhancement of fluid secretion which facilitates expectoration and eases cough.
Pharmacokinetics:
Absorption: Rapidly and completely absorbed from the gastrointestinal tract (immediate-release). Bioavailability: 79% (immediate-release); 95% (slow-release). Time to peak plasma concentration: 1-2.5 hours (immediate-release); 6.5 (slow-release).
Distribution: Rapid and pronounced distribution into blood, tissues and lungs. Crosses the placenta and enters breast milk. Volume of distribution: Approx 552 L. Plasma protein binding: Approx 90%.
Metabolism: Mainly metabolised in the liver via glucuronidation by CYP3A4 and some cleavage into dibromanthranilic acid (approx 10%) and minor metabolites. Undergoes first-pass metabolism (approx 30%).
Excretion: Via urine. Terminal elimination half-life: Approx 10 hours.
