An analytical approach of doxofylline: review

Presence of a dioxolane group inposition C-7 differentiates it from theophylline. It is a new antibronchospastic drug recently introduced in therapy withpharmacological properties like theophylline; a potent adenosine receptor antagonist. doxofylline do not affect gastric acid secretion; either invivo or in-vitro; unlike theophylline.

The lack of side effects with doxofylline indicates that the drug can be used safely and effectively. Some analytical methods for quantitative determination of doxofylline in pharmaceutical formulations like UV-Spectrophotometry, HPLC and LC-MS are reported. The present review deals with the various analytical methods reported as well as adopted for the estimation of doxofylline.CONCLUSION:Doxofylline is available and frequently used in market;hence, there is great need to determine it in bulk, dosageform as well as to estabilish pharmacokinetic parameters.The need of analytical method validation is well reflect andhighlights the aspect of analyst’s personal habits, that frompart of the developed methods, and on the possibility of aperson getting very reproducible results when he carries outthe analysis again and again in a similar set of conditions.Any developed method however, may be influenced byvariable like different elapsed assay times, different days,reagent lots, instruments, equipments or apparatus,environmental condition like temperature etc.
