Therapeutic indications:

Marbofloxacin tablets are indicated for the treatment of infections in dogs and cats associated with bacteria susceptible to marbofloxacin. Marbofloxacin and other quinolones have been shown to cause arthropathy in immature animals of most species tested, the dog being particularly sensitive to this side effect. Marbofloxacin is contraindicated in immature dogs during the rapid growth phase (small and medium breeds up to 8 months of age, large breeds up to 12 months of age and giant breeds up to 18 months of age). Marbofloxacin is contraindicated in cats under 12 months of age. Marbofloxacin is contraindicated in dogs and cats known to be hypersensitive to quinolones.

DESCRIPTION
Marbofloxacin is a synthetic broad-spectrum antibacterial agent from
the
fluoroquinolone class of chemotherapeutic agents. Marbofloxacin is the
non-proprietary
designation for 9-fluoro-2,3-
dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-
pyrido[3,2,1-ij][4,1,2] benzoxadiazine-6-carboxylic acid. The
empirical formula is
C
H
FN O and the molecular weight is 362.36. The compound is soluble in
water;
however, solubility decreases in alkaline conditions. The
N-octanol/water partition
coefficient (Kow) is 0.835 measured at pH 7 and 25°C.

CLINICAL PHARMACOLOGY
Marbofloxacin is rapidly and almost completely absorbed from the
gastrointestinal tract
following oral administration to fasted animals. Divalent cations are
generally known to
diminish the absorption of fluoroquinolones. The effects of
concomitant feeding on the
absorption of marbofloxacin have not been determined. (See DRUG
INTERACTIONS.) In
the dog, approximately 40% of an oral dose of marbofloxacin is
excreted unchanged in
the urine . Excretion in the feces, also as unchanged drug, is the
other major route of
elimination in dogs. Ten to 15% of marbofloxacin is metabolized by the
liver in dogs.
_In vitro_ plasma protein binding of marbofloxacin in dogs was 9.1%
and in cats was
7.3%. In the cat, approximately 70% of an oral dose is excreted in the
urine as
marbofloxacin and metabolites with approximately 85% of the excreted
material as

unchanged drug. Pharmacokinetic parameters related to intravenous
dosing were
estimated in a study of 6 healthy adult beagle dogs, and are
summarized in Table 1. The
absolute bioavailability following dosing of oral tablets to the same
animals was 94%.
