THERAPEUTIC CLASSIFICATION
Antibacterial Agent
ACTIONS AND CLINICAL PHARMACOLOGY
Norfloxacin is a quinolone carboxylic acid antibacterial agent for
oral administration. Norfloxacin
inhibits bacterial deoxyribonucleic acid synthesis and is
bactericidal.
At the molecular level, three specific actions have been attributed to
norfloxacin in the inhibition of
E.coli cells:
1.
inhibition of the ATP-dependent DNA supercoiling reaction catalyzed by
DNA gyrase,
2.
inhibition of the relaxation of supercoiled DNA,
3.
promotion of double-stranded DNA breakage.
Comparative Bioavailability
A comparative bioavailability study was performed using healthy human
volunteers. The rate and
extent of absorption of norfloxacin following administration of a
single (one 400 mg tablet) dose of
Apo-Norflox and Noroxin were measured and compared. The results are
summarized as follows:
