Doxophylline specifically hinders phosphodiesterase 4 in this manner unwinds bronchial smooth muscle. Be that as it may, in an unexpected way from Theophylline, Doxophylline shows up to have diminished affinities toward adenosine A1 and A2 receptors, which may account for the way better security profile of the sedate. Doxophylline is detailed to restrain platelet actuating figure (PAF) and era of leukotriene generation.

Interaction of Dophylin 400

Doxophylline ought to not be managed along side other xanthine subsidiaries. Harmful synergism with ephedrine has been reported for xanthines. Like other xanthines, concomitant treatment with troleandomycin, lincomycin, clindamycin, allopurinol, cimetidine, ranitidine, propranolol and anti-flu immunization may diminish the hepatic clearance of xanthines causing an increment in blood levels. No prove of a relationship between Doxophylline serum concentrations and harmful occasions have been detailed.

In these cases, a lower measurements of Doxophylline may be required. Phenytoin, other anticonvulsants and smoking may cause an increment in clearance with a shorter cruel half-life. In these cases higher measurements of Doxophylline may be req
