ABSTRACT
We developed an enzymatic method using nitrocefin to assay tazobactam in vitro. Tazobactam was incubated with TEM-1 beta-lactamase. Then, residual beta-lactamase activity was assayed by adding nitrocefin. This activity corresponded indirectly to the initial concentration of tazobactam. Within-assay, between-assay and accuracy coefficients of variation were below 15%. The correlation coefficients between enzymatic method and high performance liquid chromatography (the reference method)was 0.98. The enzymatic method is rapid, easy to perform and should be applied to daily clinical practice.
