U.S. Vet Ampicillin Sodium (for Horses)This treatment applies to the following species:
For Intravenous or Intramuscular Use in Horses Only
Ampicillin sodium is a semisynthetic penicillin with a broad spectrum of activity. Ampicillin is derived from the penicillin nucleus, 6-aminopenicillanic acid (6 APA). Chemically it is D(-)α-aminobenzyl penicillin sodium salt.
Ampicillin sodium provides bactericidal activity against a wide range of common Gram-positive and Gram-negative pathogens. Ampicillin’s activity occurs during the stage of active multiplication of the pathogen and acts through inhibition of biosynthesis of cell wall mucopeptide. In vivo studies have demonstrated the susceptibility of many strains of the following Gram-positive bacteria: Staphylococcus spp. and Streptococcus spp. (including S. equi).
In vivo studies have also demonstrated the susceptibility of many strains of the following Gram-negative bacteria: E. coli and Proteus mirabilis. Because it does not resist destruction by penicillinase, it is not effective against penicillinase-producing bacteria, particularly resistant staphylococci. Most strains of Pseudomonas, Klebsiella and Aerobacter are resistant.
Ampicillin sodium diffuses readily into all body tissues and fluids, with the exception of brain and spinal fluid except when the meninges are inflamed.
It produces high and persistent blood levels. Most of the ampicillin is excreted unchanged in the urine.
U.S. Vet Ampicillin Sodium (for Horses) Indications
Ampicillin sodium is indicated in the treatment of susceptible strains of the organisms causing the following infections in the horse: Respiratory tract infections (pneumonia and strangles) due to Staphylococcus spp., Streptococcus spp. (including S. equi), E. coli, and Proteus mirabilis.
Skin and soft tissue infections (abscesses and wounds) due to Staphylococcus spp., Streptococcus spp., E. coli, and Proteus mirabilis.
As with all antibiotics, appropriate in vitro culturing and susceptibility testing of samples taken before treatment should be conducted.
The use of this drug is contraindicated in animals with a history of an allergic reaction to penicillin.
Ampicillin is a semisynthetic penicillin and has the potential for producing allergic reactions. If an allergic reaction occurs, administer epinephrine and/or steroids. Possible minor irritation at the injection site may occur.
Do NOT use in horses intended for human consumption.

Directions For Use
The dry filled vials should be reconstituted immediately before use by the addition of the appropriate amount of Sterile Water for Injection, USP indicated below. This results in a final concentration of approximately 300 mg per mL.
Amount of Diluent to be Added
Stability studies with the concentrated product (300 mg/mL) demonstrated that ampicillin is stable for 1 hour at room temperature (70° - 75° F).
Ampicillin Sodium is supplied in vials containing 1gram and 3 grams of ampicillin activity.
Store dry powder at room temperature, 15° to 30°C (59° to 86°F).
