Published controlled studies on differences between men and women regarding piperacillin efficacy in adults are lacking. One study in children with febrile neutropenia showed no sex difference in treatment success of piperacillin-tazobactam.
In our opinion, the present evidence does not motivate differentiation in dosing or treatment between men and women.
Studies show conflicting results whether pharmacokinetics is altered during pregnancy or not. In one study, eight parturient pregnant women and five non-pregnant women received 4 g piperacillin i.v.. The total clearance was faster in pregnant women, and the authors suggest that pregnant women may require higher doses for effective treatment of serious infections . However, another study did not observe any difference between pharmacokinetics in pregnant versus non-pregnant women . A study in puerperal 12 women observed a lower serum levels of piperacillin during pregnancy than 6 months after pregnancy .
A randomized study compared imipenem-cilastatin (60 mg/kg/day) and piperacillin-tazobactam (360 mg/kg/day) for treatment of febrile neutropenia in children with malignant diseases (41 boys, 22 girls). The authors reported that treatment success was not correlated with the patient’s sex or primary disease .
A retrospective cohort study evaluated the risk of developing neutropenia in children <18 years old exposed to piperacillin-tazobactam (42 boys, 23 girls) compared to children exposed to ticarcillin-clavulanic acid (110 boys, 124 girls). There was an increased risk of neutropenia in the group receiving piperacillin-tazobactam and the risk was correlated with age, treatment duration, and total use, but not with the patient’s sex .
The risk of acute kidney injury was compared in hospitalized patients receiving combination of vancomycin and piperacillin-tazobactam or monotherapy with either drug in a retrospective study (148 men, 80 women). Multivariate analysis showed that monotherapy of each drug was associated with lower odds of acute kidney injury than the combination of the two drugs. Overall, women had higher odds of developing acute kidney injury during treatment with these drugs, but no sex-specific odds ratios were reported for each drug .
