Erratum to: Naunyn-Schmied Arch Pharmacol (2008) 378:203–215DOI 10.1007/s00210-008-0302-yIt has come to the attention of the journal, that a review article published last year (Postma et al. 2008) contains several passages which are identical to text published by other authors (Giembycz et al. 2008) without giving reference to the original source of these text blocks. The journal has come to the conclusion that this constitutes plagiarism and hence has decided to retract the paper.
