Serie:
Handbook of Experimental Pharmacology 200
Inhalt:
In the present volume of the Handbook of Experimental Pharmacology well known experts describe the actions of different xanthines with a focus on caffeine and theophylline. A special chapter is devoted to theobromine, an active component of chocolate, the actions of which are less well characterized. This book also presents the pharmacology of one xanthine derivative, propentofylline, as an example of a xanthine that has gone through extensive development for a novel therapeutic area.
