The more antibacterial trade names, the more consumption of antibacterials: a European study.

Recent studies have shown large differences in the use of antibacterial agents among European countries. We found a relationship between community consumption and the number of trade names of oral antibacterial agents. This relationship was observed in countries in which consumption was high, as well as in countries in which it was low, and in markets that were opened or were not opened to the sale of copies of original agents.
