Clinical Trial to Study the Safety and Effectiveness of MK0826 and Other Antibiotic Therapy in Patients With Complicated Urinary Tract Infection (0826-054)

A Phase 3, Randomized, Active Comparator-Controlled Clinical Trial to Study the Safety and Efficacy of MK0826 and Meropenem in Patients With Complicated Urinary Tract Infection

The purpose of this study is to demonstrate that MK0826 is comparable to Meropenem in the treatment of complicated Urinary Tract Infections (UTIs) in adults.

Exclusion Criteria:

• Patient has received any amount of effective concomitant antibiotic therapy after obtaining the urine culture for admission to this study (admission urine culture) and prior to the administration of the first dose of study antibiotics
• Patient's infection has been treated with greater than 24 hours of systemic antibiotic therapy known to be effective against the presumed or documented pathogens within the 72 hour period immediately prior to consideration for entry into the study
• Patient has complete obstruction of any portion of the urinary tract. Patient has a history of seizures other than an uncomplicated febrile seizure
