Product Description
Theophylline yog ib qho tshuaj methylxanthine uas ua rau cov bronchodilator tsis muaj zog. Nws muaj txiaj ntsig zoo rau kev kho mob ntev thiab tsis muaj txiaj ntsig hauv kev mob hnyav heev.
Theophylline yog ib qho methylxanthine alkaloid uas yog kev sib tw inhibitor ntawm phosphodiesterase (PDE; Ki = 100 μM). Nws kuj yog ib qho tsis xaiv antagonist ntawm adenosine A receptors (Ki = 14 μM rau A1 thiab A2). Theophylline induces so ntawm feline bronchiole cov leeg nqaij ua ntej nrog acetylcholine (EC40 = 117 μM; EC80 = 208 μM). Cov qauv uas muaj theophylline tau siv rau hauv kev kho mob hawb pob thiab mob ntsws obstructive pulmonary (COPD).
