The data, albeit limited, suggest some effects in improving airway responsiveness and inflammation Briefly, lungs were taken from mice following exposure to OVA. Effects of drugs on mucus clearance. Four different fields per slide in 8 samples from each group of mice were examined in a blinded manner.

Immunomodulatory Effects of Ambroxol on Airway Hyperresponsiveness and Inflammation

Outcomes of asthma treatments such as mortality rates were improved, but have amroxol in the last decade 2. In mice which received ambroxol prior to the OVA challenges, reduced levels of both inflammatory cells and PAS-staining goblet cell metaplasia were observed in lung tissue sections.

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

J Obstet Gynaecol Res. 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 Juranl fluid. The animals were maintained on an ovalbumin OVA -free diet. Ambroxol was added to these cultures at concentrations of 0.

Find articles by Katsuyuki Takeda. The drug was administered prior to and after allergen challenge and changes in airway inflammation and AHR were monitored.


In contrast to ambroxol treatment begun prior to OVA challenge, histological analysis revealed that ambroxol treatment initiated following Jurnxl challenge did not alter inflammatory cell infiltration or goblet cell metaplasia in the airways of OVA-sensitized and challenged mice Fig.

Effect of ambroxol on airway responses when administered after completion of the allergen challenges. Local treatment with IL is an effective inhibitor of airway hyperresponsiveness and lung eosinophilia after airway challenge in sensitized mice.

Oral N-acetylcysteine attenuates the rat pulmonary inflammatory response to antigen. Elevated protein carbonyls and lipid peroxidation products correlating with myeloperoxidase in tracheal aspirates from premature infants. Support Center Support Center. In other experiments, as illustrated in Fig. However, precise mechanisms ambrozol effects on mucus production and secretion in the pathogenesis of asthma are unclear.

Cochrane Database Syst Rev. Airway hyperresponsiveness AHRlung cell composition and histology, and cytokine and protein carbonyl levels in bronchoalveolar lavage BAL fluid were determined.

Ambroxol has been used to treat asthmatics Lung MNCs were collected and purified from mice after sensitization and challenge to OVA and cytokine levels in the supernatants of cultured cells were determined. In vitro cytokine production from lung MNCs and alveolar macrophages.

The data for RL were continuously collected for up to 3 minutes and maximum values were taken. This may indicate that the anti-oxidant properties of ambroxol target airway function with little to no effect on airway inflammation.

J Allergy Clin Immunol. 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 Based on these results, clinical trials with ambroxol to prevent or treat infant respiratory distress syndrome have been carried out 19 Cytokine levels in the BAL fluid or supernatants ammbroxol cultured cells were measured as previously described In vitro effects of ambroxol on cytokine secretion levels from cultured airway cells Lung MNCs were collected and purified from mice after sensitization and challenge to OVA and cytokine levels in the supernatants of cultured cells were determined.


Is the prevalence of asthma declining? Pharmacological and clinical update. Differential modulation of IgE-dependent activation of human basophils by ambroxol and related secretolytic analogues.

Oxidative microenvironment exerts an opposite regulatory effect on cytokine production by Th1 and Th2 cells. 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. Therefore, understanding the potential of the drug in the treatment of asthma is a valid concern. Since measured values may not be normally distributed smbroxol account of the small sample sizes, nonparametric analysis, Mann-Whitney U test, was also used to confirm that the statistical differences remained significant.

In this study, ambroxol was administrated to mice in a model of allergen-induced AHR and airway inflammation. Complement activation is critical to airway hyperresponsiveness after acute ozone exposure. IL induces eosinophil recruitment into the lung by an IL and eotaxin-dependent mechanism.

Ambroxol in the 21st century: Asthma is a complex disease in which numerous factors contribute to the characteristic features of the disease, persistent airway dysfunction including AHR and allergic airway inflammation ambroxlo Eur J Respir Dis.

These levels were decreased when ambroxol treatment was initiated after the completion of OVA challenge compared to vehicle-treated mice.
