Cefepime (hydrochloride hydrate)

Cefepime is a broad-spectrum cephalosporin antibiotic that inhibits the growth of Gram-positive and Gram-negative bacteria. It inhibits the growth of some clinical isolates of Corynebacterium, Streptococcus, and Staphylococcus (MIC90s = 0.03-8 µg/ml), but does not inhibit the growth of methicillin-resistant S. aureus (MRSA) or S. haemolyticus (MIC50s = >128 µg/ml). Cefepime inhibits the growth of some Citrobacter, Enterobacter, Klebsiella, Salmonella, Serratia, Shigella, and enteric bacilli species in addition to P. mirabilis and E. coli clinical isolates (MIC90s = =0.12-2 µg/ml). It also inhibits the growth of E. coli and Klebsiella strains that produce extended-spectrum beta-lactamase (ESBL, MIC90s = 4 and 8 µg/mL, respectively) and of indole-positive Proteae (MIC90 = 0.25 µg/ml). Cefepime inhibits the growth of pneumococci strains (MICs = 0.5-2 mg/l) in vitro and in vivo in a mouse model of peritonitis (ED50s = 0.6-1.14 mg/kg). Formulations containing cefepime have been used in the treatment of a variety of bacterial infections.Formal Name: 1-[[(6R,7R)-7-[[(2Z)-2-(2-amino-4-thiazolyl)-2-(methoxyimino)acetyl]amino]-2-carboxy-8-oxo-5-thia-1-azabicyclo[4.2.0]oct-2-en-3-yl]methyl]-1-methyl-pyrrolidinium, monochloride, monohydrochloride, monohydrate.
