Intra-abdominal infections are often polymicrobial, and include aerobic as well as anaerobic
bacteria. Antibiotics used in intra-abdominal infections should aim to cover organisms such
as Enterobacteriaceae and Bacteroides fragilis, which are the commonest organisms known to
cause such infections. Combinations of a third-generation cephalosporin, an aminoglycoside
and metronidazole are often used to treat such infections in surgical settings. An
alternative to such combinations is the use of a beta lactam - beta lactamase inhibitor
combination. Magnex (cefoperazone- sulbactam) is one such combination, which has been shown
to be as effective as a standard multidrug regimen such as gentamicin and clindamycin in the
management of intra-abdominal infections. The combination of ceftazidime, amikacin and
metronidazole has been chosen as a comparator regimen because of its broad coverage of
Gram-negative and anaerobic organisms found in such conditions.
Official title: A Randomized, Open Label, Multicentre Phase Iv Study To Evaluate The Efficacy And Safety Of Magnex (Cefoperazone-Sulbactam) In Comparison With Ceftazidime Plus Amikacin And Metronidazole In The Treatment Of Intra-Abdominal Infections

Proportion of clinical efficacy-evaluable subjects who present with continued resolution at the 30-day follow-up visit.
Adverse events as observed by the investigator or volunteered as responses to unsolicited and non-leading questions.
Vital signs including systolic and diastolic blood pressures, pulse rate and respiratory rate.
Physical examination findings.
The proportion of clinical efficacy
evaluable subjects who are classified as having a clinical outcome of success or improvement at the end of study treatment;
proportion of microbiological efficacy-evaluable subjects who have a successful microbiological outcome
success or presumed success) at the end of study treatment,
Total duration of study treatment
Comparison of pharmaco-economic data (cost effectiveness) for cefoperazone- sulbactam versus the combination of ceftazidime - amikacin - metronidazole.
Minimum age: 12 Years.
Maximum age: N/A.
- Male or female subjects aged greater or equal to 12 years
- Intra-abdominal infection documented by laparotomy or laparoscopy or percutaneous
aspiration within 24 hours prior to screening
- Presence of at least three of the following five indicators consistent with
intra-abdominal infections (Fever, leucocytosis, abdominal symptoms, abdominal signs,
- Written informed consent obtained
- Rapidly progressive illness or critically ill subjects
- Pregnant or lactating women, or women of childbearing potential not using an effective
method of contraception.
- Treatment with a presumably effective systemic antimicrobial agent for >24 hours
within a 72 hour period prior to study entry unless the subject did not sufficiently
respond to the treatment (as judged by the investigator)
