Cephapirin Benzathine

For intramammary infusion into the dry cow

Veterinary Use Only

DIN 02173255

Description

Cefa-Dri (cephapirin benzathine) for intramammary infusion into the dry cow is a product which provides a wide range of bactericidal activity against gram-positive and gram-negative organisms. It is derived biosynthetically from 7-aminocephalosporanic acid.

Active Ingredient

Each 10 mL disposable syringe contains 300 mg of cephapirin activity in a stable peanut oil gel.

Storage

Action: In the non-lactating mammary gland, Cefa-Dri provides bactericidal levels of the active antibiotic, cephapirin, for a prolonged period of time. This prolonged activity is due to the low solubility of the cephapirin benzathine and to the slow release gel base.

Cephapirin is bactericidal to susceptible organisms; it is known to be highly active against Streptococcus agalactiae.

To determine the susceptibility of bacteria to cephapirin in the laboratory, the class disc, Cephalothin Susceptibility Test Discs, 30 mcg, should be used.

Cefa-Dri Indications

For the treatment of mastitis caused by Streptococcus agalactiae in dairy cows during the dry period.

Cefa-Dri has been shown by extensive clinical studies to be efficacious in the treatment of mastitis in dry cows, when caused by Streptococcus agalactiae.

Treatment of the dry cow with Cefa-Dri is indicated in any cow known to harbour any of these organisms in the udder at drying off.

Dosage and directions for use: Cefa-Dri is for use in dry cows only. Infuse each quarter at the time of drying off with a single 10 mL syringe. Use no later than 30 days prior to calving.

Completely milk out all four quarters. The udder and teats should be thoroughly washed with warm water containing a suitable dairy antiseptic and dried, preferably using individual paper towels. Carefully scrub the teat end and orifice with 70% alcohol, using a separate swab for each teat. Allow to dry.

Cefa-Dri (cephapirin benzathine) is packaged with the protective cap.

For partial insertion: Twist off upper portion of the protective cap to expose 3-4 mm of the syringe tip.

For full insertion: Remove protective cap to expose the full length of the syringe tip.

Insert syringe tip into the teat canal and expel the entire contents of syringe into the quarter. Withdraw the syringe and gently massage the quarter to distribute the medication.

Do not infuse contents of the mastitis syringe into the teat canal if the protective cap is broken or damaged.
