Fenspiride is an oxazolidinone spiro compound used as a drug in the treatment of certain respiratory diseases. It is approved for use in Russia for the treatment of acute and chronic inflammatory diseases of ENT organs and the respiratory tract (like rhinopharyngitis, laryngitis, tracheobronchitis, otitis and sinusitis), as well as for maintenance treatment of asthma. Fenspiride is marketed under the brand names Eurespal, Pneumorel, SYRESP, Oxofen and others. Erespal (fenspiride) is a drug with a bronchodilator and spasmolytic effect, which is often used in the complex therapy of bronchial asthma. Fenspiride has a clinically proven ability to increase the activity of the cilia of the bronchial ciliated epithelium, normalize the secretion of the bronchi and reduce its viscosity. Effectively removes bronchial obstruction, restores pulmonary gas exchange. Inhibits the metabolism of arachidonic acid, in parallel blocking histamine H1-receptors, since it is histamine that stimulates the chemical reactions of the transformation of arachidonic acid into the final metabolites-factors of inflammation. Reduces the production of other mediators of inflammation - serotonin and bradykinin. It blocks α-adrenergic receptors, the activation of which increases the secretion of bronchial glands. The complex effect of fenspiride reduces the pathological effect of a number of factors that promote hypersecretion of anti-inflammatory substances and cause obstruction of the bronchial tree. Has a pronounced antispasmodic and myotropic effect.
