The metabolic transformation of the bronchospasmolytic agent doxophylline (2-(7'-theophyllinemethyl)-1,3-dioxolane) was studied in vitro with phenobarbital-induced rat liver microsomal fraction containing the NADPH-generating system. Doxophylline was poorly metabolized as 95% of the recovered material was parent compound. The major metabolite resulted:

It is assumed that theophylline (THEO) and its xanthinic derivatives inhibit lung phosphodiesterase (PDE) and block adenosine receptors in the induction of bronchodilatation. Since the theophyllinic compound ambroxol-theophylline-7-acetic acid (ATA) has been shown in vivo to be a sound bronchodilator
In an open study, 50 patients suffering from chronic obstructive pulmonary disease in an acute infectious phase were treated with ambroxol theophyllinacetate. The drug was given orally in a dosage of 100 mg BID for ten days. Viscosimetric data showed

Three methods are developed for the determination of two multicomponent mixtures containing guaiphenesine (GU) with salbutamol sulfate (SL), methylparaben (MP) and propylparaben (PP) [mixture 1]; and acephylline piperazine (AC) with bromhexine hydrochloride (BX), methylparaben (MP) and propylparaben (PP) [mixture 2].

Some esters of 7-theophyllinylacetic acid were synthetized, characterized physicochemically and tested for their anti-inflammatory properties. As compared to indomethacin, reference anti-inflammatory drug, all synthetized compounds were less toxic. The anti-inflammatory properties are influenced by the nature of the ester group
