Meropenem monotherapy for the treatment of hospital-acquired pneumonia: results of a multicenter trial.

ABSTRACT

The efficacy and tolerability of meropenem as empirical treatment in patients with hospital-acquired pneumonia was determined in a prospective, open-label, non-randomized trial. Patients from 28 centers in the USA received meropenem 1 g every 8 h intravenously. Of 255 patients enrolled, 111 were evaluable for efficacy, including 60 patients with ventilator-associated pneumonia. At end of treatment 74% of patients had a satisfactory clinical response and 64% had this response at follow-up, which could last up to 28 days after treatment. In patients with ventilator-associated pneumonia, a satisfactory clinical response was observed in 68% at the end of treatment and 63% at follow-up. The overall satisfactory response rate for individual pretreatment pathogens ranged from 65% to 100%. This study demonstrates that meropenem monotherapy is effective and well tolerated for patients with hospital-acquired pneumonia, including a subgroup of patients with ventilator-associated pneumonia.
