Summary of Clinical Use
In some jurisdictions ambroxol is used as an orally delivered expectorant drug [3]. It is not yet authorised for use by the FDA or the EMA (but is approved by individual European agencies). Clinical evaluation as an expectorant are ongoing for future US approval.
Ambroxol (as the hydrochloride) is being repurposed as a novel candidate for neurodegenerative diseases including Parkinson's disease (in particular in patients with defective β-glucocerebrosidase GBA1 genes [10,13]) [7,14] and amyotrophic lateral sclerosis (ALS; motor neurone disease; MND) [2,6].
