Pharmacology

Doxophyllin is a new type of bronchodilator. Due to the presence of a dioxolane group at position 7, it is structurally different from theophylline. Doxophyllin selectively inhibits phosphodiesterase 4, thereby relaxing bronchial smooth muscle. However, unlike theophylline, doxophylline appears to have a reduced affinity for the A1 and A2 adenosine receptors, which may be the reason for the greater safety of the drug. Doxophyllin can reportedly inhibit the production of platelet-activating factor (PAF) and leukotrienes.

Interactions of Ventofil 400

Doxophyllin should not be administered with other xanthine derivatives. The toxic synergistic effect of xanthine and ephedrine has been recorded. Like other xanthines, the combination of chlortetracycline, lincomycin, clindamycin, allopurinol, cimetidine, ranitidine, propranolol, and flu vaccines can reduce yellowing. There is no evidence that there is a relationship between serum doxophyllin concentration and toxic events.
