GentaSoothe Topical Spray (60 ml) (Manufacturer may vary)

GentaSoothe is a broad-spectrum antibiotic that kills harmful bacteria. GentaSoothe is calming and soothing because it also contains betamethasone valerate, an anti-inflammatory and anti-itch medication. The spray is quick and convenient to use because it has a metered dosing nozzle to ensure just the right amount of the medication is applied to the wound.

Key Benefits

• Treats infected lesions and wounds in dogs
• Broad-spectrum antibiotic effective against bacteria susceptible to gentamicin
• Soothing anti-inflammatory and anti-itch spray
• Convenient metered dose spray bottle ensures accurate application

Indications

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

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.

Caution:

Federal law restricts this drug to use by or on the order of a licensed veterinarian.

Contraindications:

If hypersensitivity to any of the components occurs, treatment with this product should be discontinued and appropriate therapy instituted.

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.

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 infections 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., Staphylococcus 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 McKenzie³, et al. This human bioassay technique has been found reliable for evaluating the 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:

GenOne™ 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.

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.
