ACTIONS AND CLINICAL PHARMACOLOGY
Cefuroxime axetil is an orally active prodrug of cefuroxime. After
oral administration,
cefuroxime axetil is absorbed from the gastrointestinal tract and
rapidly hydrolyzed by
nonspecific esterases in the intestinal mucosa and blood to release
cefuroxime into the blood
stream. Conversion to cefuroxime, the microbiologically active form,
occurs rapidly. The
inherent properties of cefuroxime are unaltered after its
administration as cefuroxime axetil.
Cefuroxime exerts its bactericidal effect by binding to an enzyme or
enzymes referred to as
penicillin-binding proteins (PBPs) involved in bacterial cell wall
synthesis.
This binding results in inhibition of bacterial cell wall synthesis
and subsequent cell death.
Specifically, cefuroxime shows high affinity for PBP 3, a primary
target for cefuroxime in gram-
negative organisms such as E. coli.
Comparative Bioavailability Studies
A two-way crossover, randomized, blinded, single-dose bioequivalence
study was performed on
22 normal, healthy, non-smoking male subjects under fasting
conditions. The rate and extent of
absorption of cefuroxime axetil was measured and compared following a
single oral dose (1 x
500 mg tablet) of ORB-CEFUROXIME (cefuroxime axetil) or CEFTIN®
tablets. The results
from measured data are summarized in the table on the following page:
