DESCRIPTION: Each ml contains: gentamicln sulfate equivalent to 0.57 mg gentamicin base. betamethasone valerate equivelant to 0.284 mg betamethasone, 163 mg isopropyl alcohol, propylene glycol, methylparaben and propylparaben as preservatives, purified waler q.s., Hydrochloric acid may be added to adjusl pH.

CHEMISTRY: Gentamicin is a mixture of aminoglycoside antibiotics derived from the fermentation of Micromonospora purpurea. Gentamicin sulfate is a mixture of sulfate salts of the antibiotics

produced in this fermentation . The salts are weakly acidic and freely soluble in water.

Gentamicin sulfate contains not less than 500 micrograms of gentamicin base per milligram.

Betamethasone valerate is a synthetic glucocorticoid.

Chemistry, Pharmacology and Toxicity

CHEMISTRY: Gentamicin is a mixture of aminoglycoside antibiotics derived from the
fermentation of Micromonospora purpurea. Gentamicin sulfate is a mixture of sulfate
salts of the antibiotics produced in this fermentation. The salts are weakly acidic
and freely soluble in water.

Gentamicin sulfate contains not less than 500 micrograms of gentamicin base per
milligram.

Betamethasone valerate is a synthetic glucocorticoid.

PHARMACOLOGY: Gentamicin, a broad-spectrum antibiotic, is a highly
effective topical treatment for bacterial infection of the skin In vitro ,
gentamicin is bactericidal against a wide variety of gram-positive and gram-
negative bacteria isolated from domestic animals. 1,2 Specifically, gentamicin is
active against the following organisms isolated from canine skin: Alcaligenes
sp., Citrobacter sp., Klebsiella sp., Pseudomonas aeruginosa , indole-positive
and -negative Proteus sp., Escherichia coli , Enterobacter sp., Staphlyococcus sp.
and Streptococcus sp.

Betamethasone valerate emerged from intensive research as the most
promising of some 50 newly synthesized corticosteroids in the
experimental model described by McKenzie,3 et al. This human bioassay
technique has been found reliable for evaluating vasoconstrictor
properties of new topical corticosteroids and is useful in predicting clinical
efficacy.

Betamethasone valerate in veterinary medicine has been shown to provide
anti-inflammatory and antipruritic activity in the topical management of
corticosteroid-responsive infected superficial lesions in dogs.

TOXICITY: Gentamicin sulfate with betamethasone valerate topical spray
was well-tolerated in an abraded skin study in dogs. No treatment-related
toxicological changes in the skin were observed.

Systemic effects directly related to treatment were confined to histological
changes in the adrenals, liver and kidney and to organ-to-body
weight ratios of adrenals. All were dose related, were typical for or not
unexpected with corticosteroid therapy and were considered reversible
with cessation of treatment.

Warning

WARNING: Clinical and experimental data have demonstrated that
corticosteroids administered orally or parenterally to animals may induce the
first stage of parturition when administered during the last trimester of
pregnancy and may precipitate premature parturition followed by dystocia,
fetal death, retained placenta and metritis.

Additionally, corticosteroids administered to dogs, rabbits and rodents
during pregnancy have produced cleft palate. Other congenital anomalies,
including deformed forelegs, phocomelia and anasarca, have been
reported in offspring of dogs which received corticosteroids during
pregnancy.

Indications and contraindications

INDICATIONS: For the treatment of infected superficial lesions in dogs
caused by bacteria susceptible to gentamicin.

CONTRAINDICATIONS: If hypersensitivity of any of the components
occurs, discontinue treatment and institute appropriate therapy.

Dosage and Administration:

DOSAGE AND ADMINISTRATION: Prior to treatment, remove excessive
hair and clean the lesion and adjacent area. Hold bottle upright 3 to 6
inches from the lesion and depress the sprayer head twice. Administer 2
to 4 times daily for 7 days.

Each depression of the sprayer head delivers 0.7 mL of Gentamicin
Sulfate With Betamethasone Valerate Topical Spray.

Side Effects and Precautions

SIDE EFFECTS: Side effects such as SAP and SGPT enzyme
elevations, weight loss, anorexia, polydipsia and polyuria have occurred
following parenteral or systemic use of synthetic corticosteroids in dogs.
Vomiting and diarrhea (occasionally bloody) have been observed in dogs.

Cushing’s syndrome in dogs has been reported in association with
prolonged or repeated steroid therapy.

PRECAUTIONS: Antibiotic susceptibility of the pathogenic organism(s)
should be determined prior to use of this preparation. Use of topical
antibiotics may permit overgrowth of non-susceptible bacteria, fungi or
yeasts. If this occurs, treatment should be instituted with other
appropriate agents as indicated.

Administration of recommended dose beyond 7 days may result in
delayed wound healing. Animals treated longer than 7 days should be
monitored closely.

Avoid ingestion. Oral or parenteral use of corticosteroids, depending on
dose, duration and specific steroid may result in inhibition of endogenous
steroid production following drug withdrawal.

In patients presently receiving or recently withdrawn from systemic
corticosteroids treatments, therapy with a rapidly acting corticosteroid
should be considered in especially stressful situations.

If ingestion should occur, patients should be closely observed for the
usual signs of adrenocorticoid overdosage, which includes sodium
retention, potassium loss, fluid retention, weight gains, polydipsia and/or
polyuria. Prolonged use or overdosage may produce adverse
immunosuppressive effects.
