Condition acinetobacter infections
Treatment sulbactam
Phase phase 4
Sponsor Sutep Jaruratanasirikul
Collaborator Prince of Songkla University
Start date September 2014
End date August 2016
Trial size 18 participants
Trial identifier NCT02688322, SULBAC552011411


Acinetobacter species have emerged as agents of serious nosocomial infections in critically ill patients. Only a few effective antibiotics are currently available for the treatment of this pathogen and, therefore, sulbactam is being considered as an alternative treatment option. The aims of this study were to i) reveal the population pharmacokinetics and ii) assess the probability of target attainment (PTA) of sulbactam in septic critically ill patients caused by Acinetobacter spp. infections.

The study was conducted in septic critically ill patients caused by Acinetobacter spp. Each patient received 2 g every 12 h of sulbactam for 10 days, after which PK studies were carried out on day 4 of sulbactam therapy and a Monte Carlo simulation was performed to determine the probability of attaining a specific pharmacodynamic target.

Study Design

Endpoint classification pharmacokinetics/dynamics study
Intervention model single group assignment
Masking open label
2 g of sulbactam in 100 ml of normal saline solution was administered via an infusion pump at a constant flow rate 1 h every 12 h.
2 g in 100 ml of normal saline solution and administered via an infusion pump at a constant flow rate 1 h every 12 h. Blood samples (approximately 5 ml) will be obtained by direct venepuncture at the following time: 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8 and 12 h after 7th dose of sulbactam

Primary Outcomes

concentration of sulbactam in plasma
time frame: 12 h profile after 7th of sulbactam
