This article unfortunately contained errors in two places.

1. The two columns of data in Table 1 were under the wrong headings. The correct version of Table 1 is given here:

2. Incorrect percentages were given in the last paragraph of the “Results” section, immediately before the “Discussion”. The corrected paragraph is as follows:

In 2005 in the prescription (Rx) group of N2B analgesics, combination products accounted for approx. 33% of all Rx analgesics in terms of SU. The most important combinations are tilidine plus naloxone (14% of all SU in the Rx group), followed by codeine plus paracetamol (12%). The predominating single products in the Rx group are metamizole (36%) and tramadol (21%). Growth in the Rx group can be seen for both the combinations named and the single products.
