Use Seretide Multidisk is a combined medication containing salmeterol and fluticasone propionate, which have different mechanisms of action. Salmeterol prevents the onset of bronchospasm symptoms, while fluticasone propionate improves lung function and prevents disease exacerbations. Salmeterol is a selective long-acting (up to 12 hours) beta2-adrenoreceptor agonist, providing more prolonged bronchodilation than short-acting beta2-adrenoreceptor agonists. Fluticasone propionate belongs to the group of topical glucocorticosteroids and, when administered by inhalation in recommended doses, exerts a pronounced anti-inflammatory and anti-allergic effect in the lungs, leading to a reduction in clinical symptoms and a decrease in the frequency of bronchial asthma exacerbations.
