Results of the Monte Carlo simulation with the fractional target attainments against a range of MICs were determined for the following regimens: 4 g piperacillin administered intravenously (i.v.) for either 30 min or 4 h every 8 h as well as for 30 min or 3 h every 6 h (A), and 3 g piperacillin administered i.v. for either 30 min or 4 h every 8 h as well as 4 g piperacillin administered i.v. for 30 min or 3 h every 6 h (B).
