title: [Bronchodilator effect of methylxanthine derivatives (author's transl)].
abstract: The bronchodilator effect of theophylline ethylenediamine was compared with that of a combination of the methylxanthines theophylline, diprophylline and proxyphylline, after administration of slow-release capsules. At an initial dose of twice two capsules the two drug preparations produced similar, therapeutically significant, effects. When reducing the dose to twice one capsule, during long-term treatment, there was a clinically and statistically significantly greater bronchodilator effect among those patients receiving the combined methylxanthine preparation.
