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

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:

A study has been made of the bronchospasmolytic actions of theophylline and some ot its N-7-substituted derivatives administered by i.v infusion in anaesthetized guinea pigs, in which experimental bronchial asthma was induced by i.v. administration of histamine, 5-hydroxytryptamine and bradykinin.

A sensitive and specific method for the estimation of theophylline-7-acetic acid in plasma by high performance liquid chromatography is described. Acidified plasma is extracted with chloroform-n-butanol (85: 15), back extracted with phosphate buffer (0.5 mmol-1, pH 6.5), and finally the
