INTRODUCTION : Teicoplanin is an effective treatment option against methicillin-resistant, Gram-positive bacteria, like Staphylococcus
aureus. It is a glycopeptide antibiotic, produced through microbial fermentation, a process resulting in variations in the N-acyl
side chain. Concerns that these variations may affect the pharmacokinetic profile and the clinical efficacy of generic teicoplanin
preparations have been raised.
METHOD : To address this issue, a multi-centre observational study was conducted to evaluate steady-state peak and trough serum
concentrations, and the serum bactericidal activity (SBA) and safety of a generic teicoplanin preparation in critically ill patients.
Additionally, the composition of the generic teicoplanin was compared to that of the innovator drug to assess differences in the
composition.
RESULTS: Following pre-determined loading and maintenance dose schedules, the mean peak and trough teicoplanin serum
concentrations were 20.98 mg/l and 10.38 mg/l, respectively. A statistically significant association was observed between
teicoplanin pharmacotherapy and increased ex vivo SBA. It was found using independent analysis that the composition of
the generic teicoplanin preparation was similar to that of the innovator drug, and that both formulations met the European
Pharmacopoeia specifications.
CONCLUSION : The loading and maintenance schedules employed in this study were effective in establishing therapeutic serum
teicoplanin concentrations in critically ill patients. Evidence of bactericidal activity measured in patients’ ex vivo serum samples,
following treatment with the generic preparation, supports this finding. |
