Ambroxol-D5 is intended for use as an internal standard for the quantification of ambroxol by GC- or LC-MS. Ambroxol (
T0920) is an expectorant and
active metabolite of bromhexine. It decreases short-circuit currents in electrically stimulated isolated canine tr
acheal epithelial cells when applied sub
mucosally. Ambroxol (
T0920) decreases IL-13-induced production of
mucin 5
AC (
MUC5AC) in primary human airway epithelial cells and inhibits IL-13-induced decreases in the
mucociliary transport rate of endogenous particles in the same cells. Ambroxol (
T0920) increases phenol red secretion, a marker of expectorant
activity, in mice when administered at doses of 30, 60, or 120 mg/kg. Formulations containing ambroxol have been used in the treatment of
acute or chronic respiratory conditions.
