  • Title: Prospective randomized comparative studies of mezlocillin/cefotaxime vs. gentamicin/cefoxitin.
    Author: Kosmidis J, Daikos GK.
    Journal: J Antimicrob Chemother; 1983 May; 11 Suppl C():91-5. PubMed ID: 6311782.
    Abstract:
    In 54 patients suffering from a variety of severe systemic infections the combination of mezlocillin (4 g iv 6-hourly) plus cefotaxime (2 g iv 8-hourly) was compared to that of gentamicin (1.5 mg/kg im or iv 8-hourly) plus cefoxitin (2 g iv 6-hourly). In the gentamicin/cefoxitin group metronidazole (500 mg iv 8-hourly) was added for anaerobic infections. Treatment assignment was randomized. The patients' diagnoses were: pyelonephritis (24), pneumonia (14), infected burns (9), osteomyelitis (2), and abdominal infections (5). Pathogens included: Escherichia coli (31), other Enterobacteriaceae (21), Pseudomonas aeruginosa (13), anaerobes (4), and others (2). Treatment with mezlocillin/cefotaxime cured 20 (74%) of 27 patients and caused improvement in 5, while in 19 (70%) patients the pathogens were eradicated. In the gentamicin/cefoxitin group 17 (63%) of 27 patients were cured and 6 improved, while in 15 (56%) pathogens were eradicated. One patient in the first group developed a rash, while in the second group two patients developed thrombophlebitis and another two transient nephrotoxicity. The combination of mezlocillin and cefotaxime can be recommended for the rational and empirical treatment of serious systemic infections.
