A review of the antibacterial activity of 6-[(R)-2-[3-methylsulfonyl-2-oxo-imidazolidine-carboxamido]-2-phenyl-acetamido]-penicillanic acid sodium salt (mezlocillin, Baypen) and 6-[(R)-2-(2-oxo-imidazolidine-1-carboxamido)-2-phenyl-acetamido]-penicillanic acid sodium salt (azlocillin, Securopen) is given on the basis of extensive in vitro studies. The action of each of the preparations is compared with that of important antibiotics of other substance classes from the group of penicillins and cephalosporins.
