    4.5 Special precautions for use

Special precautions for use in animals

    The product is efficient only against bacterial strains most sensitive to chlortetracycline. Use of the product should be based on susceptibility testing of the bacteria isolated from the animal. If this is not possible, therapy should be based on local (regional, farm level) epidemiological information about susceptibility of the target bacteria.

    Inappropriate use of the product may increase the prevalence of bacteria resistant to chlortetracycline and may decrease the effectiveness of treatment with related substances, due to the potential for cross-resistance.

    Long term use of this product is not recommended as it may lead to the development of bacterial resistance.

    Special precautions to be taken by the person administering the veterinary medicinal product to animals

    Handle this product with care to avoid exposure when adding to feed and administering medicated feed to the animals.

    Take adequate measures to avoid dust formation when adding the product to feed.

    Those handling the product should do so in a mechanically ventilated area.

    Wear either a disposable half-mask respirator conforming to European Standard EN149 or a non-disposable respirator to European Standard EN 140 with a filter to EN 143.

    Direct contact of the product with the skin, eyes and mucous membranes should be avoided.

    Wear protective gloves, overalls and approved safety glasses.

     In case of accidental exposure, wash area immediately with water.

Do not smoke, eat or drink when handling the product.

    Hands and exposed skin should be washed thoroughly after use.

Other precautions

None.

4.6 Adverse reactions (frequency and seriousness)

    Chlortetracycline toxicity is low. If digestive disturbances do occur, treatment should be discontinued.

    On rare occasions the following adverse reactions may occur: allergic reactions and photosensitivity; gastrointestinal disorders; disorders of the liver and the kidneys. If suspected adverse reactions occur, treatment should be discontinued.

    See section 4.7

    4.7 Use during pregnancy, lactation or lay

    The use is not recommended during pregnancy or lactation. The treatment of pregnant animals with chlortetracycline may result in adverse effects on skeletal and tooth development in the foetus. Therefore, the product should be used only in pregnant sows according to the benefit/risk assessment of the responsible veterinarian.

4.8 Interaction with other medicinal products and other forms of interaction

    This product is not recommended for concurrent administration with any other oral medication. 2+Do not incorporate the product in feed overloaded with polyvalent cations such as Ca 3+and Fe because the formation of chlortetracycline complexes with these cations is possible.

    Do not administer together with antacids, kaolin and iron preparations and in conjunction with bactericidal antibiotics like beta-lactams.

    The product should not be used in case of known resistance to other tetracyclines.

4.9 Amounts to be administered and administration route

    For oral administration after incorporation in a feeding stuff by a facility licensed to medicate feed.

Administration:

    The recommended therapeutic dose is 20 mg per kg bodyweight daily i.e. 20 grams of Chloromed 150 mg/g Premix per 150 kg bodyweight.

    For the preparation of the medicated feed the body weight of the animals to be treated and their actual intake of feed should be taken into account. To ensure the correct dosage and to avoid under-dosing, the body weight should be determined as accurately as possible. The required dose should be measured by suitably calibrated weighing equipment. During the treatment period, only feed medicated with the product should be supplied. To provide the required amount of active substance per kg medicated feed the premix has to be incorporated into the feed according to the following formula:

... mg Chloromed/kg bw/day x Average bw (kg) of animals to be treated ; ... mg Chloromed/kg of feedAverage daily feed intake (kg/animal)

Treatment should be continued for a period of seven days. If animals don’t recover within

    3 days after oral medication, diagnosis should be reconsidered and treatment should be changed, if necessary.

    The uptake of medicated feed depends on the clinical condition of the animals. In order to achieve the correct dosage the chlortetracycline hydrochloride inclusion rate in feed should be adjusted for feed intake.

Pelleting should not be conducted at temperatures in excess of 70?C.

5. PHARMACOLOGICAL PROPERTIES

Pharmacotherapeutic group: Tetracycline for systemic use.

    ATCvet code: QJ01AA03

5.1 Pharmacodynamic properties

    Chlortetracycline hydrochloride is a predominantly bacteriostatic antibiotic, interfering with bacterial protein synthesis of the rapidly growing and reproducing bacterial cell. Chlortetracycline has a broad spectrum of activity, including Gram-positive aerobes, Gram-negative anaerobes and Mycoplasmas. Resistance is known to occur in respiratory pathogens of pigs and cross-resistance occurs between chlortetracycline and other tetracyclines.

    The Clinical and Laboratories Standards Institute (CLSI) breakpoints established for tetracyclines are as follows:

    Organisms other than streptococci: S: ? 4μg/ml, I: 8 μg/ml; R: ? 16 μg/ml.

5.2 Pharmacokinetic particulars

    Following oral administration, maximum blood levels are achieved within approximately 2-8 hours. Steady state plasma concentrations of chlortetracycline are maintained throughout the twice daily seven day treatment period.

6. PHARMACEUTICAL PARTICULARS

6.1 List of excipients

Medium Chain Triglycerides.

    Soya Bean Meal.

    Colloidal Anhydrous Silica.

6.2 Incompatibilities
