[Aggressive behavior as a side effect of ethylenediamine (but not of theophylline)].

In accordance with a case report of a 7-year-old boy with bronchial asthma, who was twice treated with aminophylline and each time reacted upon this with an aggressive behaviour, which was completely abolished after stopping the medication and which did not appear after application of theophylline, we became suspicious, that this side effect could be due only to the ethylenediamine.
