beta-HET (beta-Hydroxyethyltheophylline), the major metabolite of the antibronchospastic, antiasthmatic drug doxofylline was studied in several in vitro and in vivo trials to characterize its pharmaco-toxicological profile. When compared to the parent compound, beta-HET was found to be significantly less active.
