Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with obesity who are hospitalized and have recently started piperacillin-tazobactam.

Probably not a fit

Patients with documented allergies to beta-lactams, those undergoing renal replacement therapy, or those with a history of seizures may not benefit from this study.

What this trial studies

This study evaluates the effectiveness of piperacillin-tazobactam in patients with obesity by comparing the pharmacodynamic parameters achieved through prolonged intermittent infusion versus standard infusion. It is an open randomized controlled trial focusing on hospitalized adults with a body mass index of 30 kg/m² or higher. The primary goal is to determine the proportion of patients achieving a favorable pharmacodynamic target after 24 hours of treatment. The study is conducted at Hôpital Charles-Le Moyne in Quebec.

Why it matters

Potential benefit: If successful, this study could optimize antibiotic treatment for obese patients, potentially improving infection outcomes.

How similar studies have gone: While this approach is novel in the context of obesity, similar studies have shown the importance of pharmacodynamics in optimizing antibiotic therapy.
