Four different fields per slide in 8 samples from each group of mice were examined in a blinded manner.

Ambroxol in the 21st century: pharmacological and clinical update.

Local treatment with IL is an effective inhibitor of airway hyperresponsiveness and lung eosinophilia after airway challenge in sensitized mice. Antioxidant function of ambroxol in mononuclear and polymorphonuclear cells In vitro. S-carboxymethylcysteine normalises airway responsiveness in sensitised and challenged mice.

In asthma, airway mucus hypersecretion is thought to be a pathophysiological feature and contributor to morbidity and mortality 4. Eur J Respir Dis. J Obstet Gynaecol Res. However, precise mechanisms and effects on mucus production and secretion in the pathogenesis of asthma are unclear.

Cellspecific modulation of surfactant proteins by ambroxol treatment. Effect ambroxpl ambroxol on airway responses when administered after completion of the allergen challenges. Author information Article notes Copyright and License information Disclaimer. Measurement of cytokines Cytokine levels in the BAL fluid or supernatants from cultured cells were measured as previously described Cytokine secretion levels from alveolar macrophages were analyzed following culture with OVA and ambroxol Fig.


Immunomodulatory Effects of Ambroxol on Airway Hyperresponsiveness and Inflammation

In contrast to ambroxol treatment begun prior to OVA challenge, histological analysis revealed that ambroxol treatment initiated following OVA challenge did not alter inflammatory cell infiltration or goblet cell metaplasia in the airways of OVA-sensitized and challenged mice Fig. Cochrane Database Syst Rev. Is the prevalence of asthma declining? Outcomes of asthma treatments such as mortality rates were improved, but have stalled in the last decade 2.

In summary, administration of ambroxol was shown to normalize AHR when given either prior to or after completion of allergen challenge in previously sensitized mice.

Ambroxol is a metabolite of bromhexine, which has been used in the therapy of airway diseases since the late s B Cell composition in BAL fluid. Why aren’t we doing better in asthma: Ambroxol decreases bronchial hyperreactivity. Ambroxol treatment prior to allergen challenge reduced BAL eosinophils and Th2 cytokines, while the same treatment begun after completion of the allergen challenges also impacted cytokine levels and levels of protein carbonyls in BAL fluid.

However, the mechanisms underlying these effects are not well understood. Find articles by Nobuaki Miyahara.

A second effect of the drug may lie in the anti-oxidant activity. Find articles by Astushi Hirano. Abstract Ambroxol is used in COPD and asthma to increase mucociliary clearance and regulate surfactant levels, perhaps through anti-oxidant and anti-inflammatory activities.


Elevated protein carbonyls and lipid peroxidation products correlating with myeloperoxidase in tracheal aspirates from amborxol infants. Therefore, reduction of Th2 cytokines in the airways by ambroxol may be a cause of the reductions in AHR and airway inflammation induced by allergen.

Effects of ambroxol on spontaneous or stimulated generation of reactive oxygen species by bronchoalveolar lavage cells harvested from jyrnal with jurnaal without chronic obstructive pulmonary diseases. Ambroxol or saline were administrated following OVA challenge. The data, albeit limited, suggest some effects in improving airway responsiveness and inflammation Asthma is the most prevalent chronic respiratory disease and the prevalence is still increasing 1.

Immunomodulatory Effects of Ambroxol on Airway Hyperresponsiveness and Inflammation

In parallel, airway responsiveness in response to inhaled MCh was decreased while eosinophil numbers were not altered. The drug was administered prior to and after allergen challenge and changes in airway inflammation and AHR were monitored.

Safe and cost-effective therapeutic alternatives are needed.
