Description:
Mechanism of Action: Ambroxol is a mucolytic agent that increases respiratory tract secretion by enhancing the production of pulmonary surfactants and stimulating ciliary activity. This results in the improvement of mucociliary clearance and enhancement of fluid secretion which facilitates expectoration and eases cough.
Onset: Rapid (loz); within 2 hours (oral solution and syr).
Duration: ≥3 hours (loz).
Pharmacokinetics:
Absorption: Rapidly and completely absorbed (immediate-release). Bioavailability: 79% (immediate-release); 95% (slow-release). Time to peak plasma concentration: 1-2.5 hours (immediate-release); 6.5 hours (slow-release).
Distribution: Rapid and pronounced distribution into body tissues with the highest concentration in the 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 and minor metabolites; undergoes first-pass metabolism.
Excretion: Mainly via urine (approx 83%). Elimination half-life: Approx 10 hours.
