A New Fixed Dose Combination of Ceftriaxone + Sulbactam + Disodium Edetate for Definitive Treatment of Infections Due to Piperacillin/ Tazobactam Resistant Bacteria: A Retrospective Efficacy and Pharmacoeconomic Study
Journal Title: Journal of Advances in Medicine and Medical Research - Year 2016, Vol 15, Issue 4
Abstract
Objective: Present retrospective study was aimed to analyze comparative efficacy of fixed dose combination (FDC) (ceftriaxone + sulbactam + disodium edetate) and meropenem used alone or in combinations with other antibiotics for management of intensive care unit (ICU) patients suffering with infections from piperacillin-tazobactam (pip-taz) resistant bacteria and to assess the costs associated with respective therapies. Methodology: Patients records were collected and their demographic characteristics, infection types, co-morbidities, antibiotic therapy, dosage, treatment duration microbial and clinical success rates were evaluated. Effectiveness and costs analysis between antibiotic regimens were estimated in Indian rupees (INR). A total of 136 patients data treated at a tertiary-care hospital was analyzed. These 136 patients included 28, 18, 19, 17, 31 and 23 patients of urinary tract infection (UTI), blood stream infection (BSI), community acquired infection (CAI), skin structure infection (SSI), intra-abdominal infection (IAI) and ventilator associated pneumonia (VAP), respectively. Out of 136 patients, 56 patients received FDC and another 80 patients were administered with meropenem empirically. Results: Clinical cure observed was 71.42% and 67.50% in FDC and meropenem groups, respectively. The patients in whom meropenem and FDC treatment regime failed to show improvement, colistin was given as an additional cover, which resulted in clinical cure of 86.95% and 85.71% patients respectively. Comparative cost expenditure analysis of these two drug treatment regimens revealed that, the overall treatment cost for patients cured with antibiotic regimen containing meropenem was 107.39% more than that of FDC. The strongest contributors of the increase in treatment costs were cost of antibiotic, number of dosages, average treatment duration and clinical failure rates. Conclusion: Infections with pip-taz resistant bacteria are frequent in ICU patients and the present study demonstrates that FDC has comparatively similar efficacy as that of meropenem which is considered as an appropriate option to treat pip-taz resistant cases. Pharmacoeconomic analysis clearly advocates in favor of FDC as a cheaper and safer alternative to meropenem to treat ICU patients with infections caused due to pip-taz resistant bacteria.
