When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.   NOTE: CEFUROXIME AXETIL TABLETS AND CEFUROXIME AXETIL FOR ORAL SUSPENSION ARE NOT BIO­EQUIVALENT AND ARE NOT SUBSTITUTABLE ON A MILLIGRAM-PER-MILLIGRAM BASIS (SEE CLINICAL PHARMACOLOGY).   Cefuroxime Axetil Tablets: Cefuroxime axetil tablets are indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below:   1.    Pharyngitis/Tonsillitis caused

DESCRIPTION
Cefuroxime axetil tablets contain cefuroxime as cefuroxime axetil.
Cefuroxime axetil is a
semisynthetic, broad-spectrum cephalosporin antibiotic for oral
administration.
Chemically, cefuroxime axetil, the 1-(acetyloxy) ethyl ester of
cefuroxime, is (_RS _)-1-hydroxyethyl
(6_R_,7_R_)-7-[2-(2-furyl)glyoxyl-amido]-3-(hydroxymethyl)-8-oxo-5-thia-1-azabicyclo[4.2.0]-oct-2-ene-
2-carboxylate, 7 -(_Z_)-(_O_-methyl-oxime), 1-acetate 3-carbamate. Its
molecular formula is
C
H N O S, and it has a molecular weight of 510.48.
Cefuroxime axetil is in the amorphous form and has the following
structural formula:
Cefuroxime axetil tablets are uncoated and contain the equivalent of
125, 250 or 500 mg of cefuroxime
as cefuroxime axetil. Cefuroxime axetil tablets contain the inactive
ingredients colloidal silicon
dioxide, croscarmellose sodium, hydrogenated vegetable oil,
microcrystalline cellulose and sodium
lauryl sulfate.
CLINICAL PHARMACOLOGY
ABSORPTION AND METABOLISM: After oral administration, cefuroxime
axetil is absorbed from the
gastrointestinal tract and rapidly hydrolyzed by nonspecific esterases
in the intestinal mucosa and blood
to cefuroxime. Cefuroxime is subsequently distributed throughout the
extracellular fluids. The axetil
moiety is metabolized to acetaldehyde and acetic acid.
PHARMACOKINETICS: Approximately 50%of serum cefuroxime is bound to
protein. Serum
pharmacokinetic parameters for cefuroxime axetil tablets are shown in
Table 1.
