MUCERA SYRUP 15MG/5ML AMBROXOL HCI COMPOSITION Each 5 mL syrup contains: Ambroxol HCI 15 mg Preservatives: Sodium benzoate 12.5mg PRODUCT DESCRIPTION Red solution , sweet and slightly bitter taste with strawberry odour PHARMACODYNAMICS The major pharmacodynamic actions of ambroxol are surfactant stimulation, mucokinetic and secretagogue activity. The therapeutic activities of the drug in animal models of the infant and adult respiratory distress syndrome (IRDS and ARDS) are reviewed. SO2 exposed rats, which exhibited increased airway resistance and work of breathing, were used as an animal model of a bronchitic syndrome. The active group was treated with 25 mg kg-1 oral ambroxol for 10 days. The airway resistance of this group (53.6 +/- 7.0 Pa.ml-1.s) was significantly lower than that of the control (81.2 +/- 11.4). Specific work of breathing was also lower in the treated group (0.26 +/- 0.02 mJ.ml-1, control: 0.35 +/- 0.029). The alleviation of airflow limitation was a consequence of subacute treatment and not of acute bronchodilatation. Treatment with the beta 2-adrenergic drug clenbuterol further improved both active and placebo groups. (Dr. Karl Thomae GmbH, Department of Biological Research, Biberach an der Riss, Fed. Rep. Germany; The pharmacology of ambroxol--review and new results. Eur J Respir Dis Suppl. 1987;153:255-62.) The mucokinetic activity of ambroxol was demonstrated as an increase in mucus or particle transport rate on the frog palate and in guinea pig tracheas. To clarify the mechanism we examined the influence of the drug on the ciliary beat frequency (CBF) of isolated cells from guinea pig tracheas. Ambroxol significantly stimulated the CBF up to 10.8%, salbutamol up to 19.5%. The effect of ambroxol on CBF certainly contributes to, but does not explain the more pronounced increase in transport rate. Thus a stimulation of the mucociliary transport rate by the other major pharmacodynamic mechanisms, secretagogue activity and stimulation of pulmonary surfactant, has to be considered.
