Cyclosol LA
Active substance
ATC code
Species
Cattle and pigs.
Indications
Cattle: For the treatment of respiratory infections caused by oxytetracycline susceptible organisms such as Arcanobacterium (Actinomyces) pyogenes and Haemophilus somnus.
Pigs: For the treatment of respiratory infections caused by oxytetracycline susceptible organisms such as Pasteurella Multocida.
Dose to be administered and administration route
Administration route: intramuscular use (deep). It is strongly recommended to divide the intramuscular dosages over two or more injection sites - maximum 15 ml per injection site in cattle over 150 kg body weight and 7 ml in pigs and calves. Injection sites should be alternated.

Cattle and pigs.
4.2 Indications for use, specifying the target species

Pigs: For the treatment of respiratory infections caused by oxytetracycline susceptible organisms such as Pasteurella Multocida.
4.3 Contraindications

Do not use in animals with an impaired liver and/or kidney function.
4.4 Special warnings for each target species
None.
4.5 Special precautions for use
Special precautions for use in animals
For the 250 mL pack, the use of a multidose syringe is recommended. To refill the syringe, the use of a draw off needle is recommended to avoid excessive broaching of the stopper.
It is recommended to use the veterinary medicinal product in the early stages of disease and to evaluate the response to treatment within 72 hours. Resistance against oxytetracycline may vary. Use of the veterinary medicinal product should be based on susceptibility testing and taking into account official and local antimicrobial policies.
Inappropriate use of the veterinary medicinal product may increase the prevalence of bacteria resistant to oxytetracycline and may decrease the effectiveness of treatment with tetracyclines due to the potential for cross resistance.
Because oxytetracycline can retard foetal skeletal development and may cause discoloration and enamel hypoplasia of foetal teeth, the veterinary medicinal product should be used cautiously in the last half of pregnancy.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
People with known hypersensitivity to tetracyclines should avoid contact with the veterinary medicinal product.
The direct or indirect contact of the user via skin or mucosa should be avoided because of the risk of sensitisation. Wash hands after use. In case of contact with eyes or skin, wash immediately with water as irritation may occur.
Laboratory studies in rabbits and rats conducted with the excipient N-methyl pyrrolidone have shown evidence of foetotoxic effects. Women of childbearing age, pregnant women or women suspected of being pregnant should use the veterinary medicinal product with serious caution to avoid accidental selfinjection.
Special precautions for the protection of the environment Not applicable.
Other precautions Not applicable.

Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder or its local representative or the national competent authority via the national reporting system. See the package leaflet for contact details.
4.7 Use during pregnancy, lactation or lay
The placenta is readily passed by oxytetracycline and concentration in the foetal blood may reach those of the maternal circulation, although concentration is usually somewhat lower. The use is not recommended in the last 2-3 weeks of pregnancy.
The safety of the veterinary medicinal product has not been established in cattle and pigs during pregnancy until 3 weeks before expected partus, lactation or in animals intended for breeding. Laboratory studies in rabbits and rats conducted with the excipient N-methyl pyrrolidone have shown evidence of foetotoxic effects. Use only according to the benefit-risk assessment by the responsible veterinarian.
Tetracyclines are deposited in deciduous and permanent teeth causing discoloration, enamel hypoplasia, and reduced mineralisation. Tetracyclines can retard foetal skeletal development. Oxytetracycline is excreted in the milk; concentrations are generally low.
4.8 Interaction with other medicinal products and other forms of interaction
Oxytetracycline should not be administered simultaneously with penicillins or cephalosporins.
4.9 Amount(s) to be administered and administration route
Administration route: intramuscular use (deep). It is strongly recommended to divide the intramuscular dosages over two or more injection sites - maximum 15 ml per injection site in cattle over 150 kg body weight and 7 ml in pigs and calves. Injection sites should be alternated.
Pigs
20 mg oxytetracycline per kg bodyweight, if necessary repeat after 72 hours.
Cattle not producing milk for human consumption
20 mg oxytetracycline per kg bodyweight, if necessary repeat after 72 hours.
Cattle producing milk for human consumption
20 mg oxytetracycline per kg bodyweight as a single injection only.
To ensure a correct dosage, body weight should be determined as accurately as possible.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
After intramuscular administration of the antibiotic in lethal dosages, central nervous system symptoms as excitation and convulsions, followed by depression, generalized muscular paralysis and respiratory arrest, preceding death were observed (death usually occurs through respiratory failure). Longterm treatment may result in gastrointestinal disturbances and changes of gut flora (supra-infections). High dosages or chronic administration of oxytetracycline may delay bone growth and healing in young animals. Chronic overdose may lead to drug accumulation and nephrotoxicity. There are no known antidotes to oxytetracycline toxicity.
4.11 Withdrawal period(s)
Cattle: Meat and offal: 35 days.
Milk: 8 days.
Pigs: Meat and offal: 28 days.
5. PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Tetracycline antimicrobial
ATCvet code: QJ01AA06
5.1 Pharmacodynamic properties
Oxytetracycline is a bacteriostatic antibiotic. It exerts its action by inhibiting the protein synthesis of the bacterial cell. Inhibition of bacterial protein synthesis results in disturbance of all functions necessary for the life of bacteria, especially cell-division, and the formation of the cell wall are impaired.
Resistance is usually plasmid-mediated. Micro-organisms that have become resistant to one tetracycline frequently exhibit resistance to the others.
5.2 Pharmacokinetic particulars
Absorption of oxytetracycline following intramuscular injection of the veterinary medicinal product is fast. In pigs the Cmax is measured within 2 to 3 hours; the Cmax is approximately 4 µg/ml. In cattle absorption is somewhat slower; the Cmax is measured after 3 to 5 hours; the Cmax is approximately 3 to 6 µg/ml.
A plasma concentration of 0.5 µg/ml or more is maintained for 72 hours in cattle and pigs. Concentrations of 0.1 μg/ml are maintained for 5 days. Bioavailability of the veterinary medicinal product is approximately 100%.
High concentrations of oxytetracycline are detectable in kidney, liver, and urine, but oxytetracycline is widely distributed in the body, including lungs and muscle. The placenta is readily passed by oxytetracycline and concentration in the foetal blood may reach that of the maternal circulation.
Oxytetracycline apparently is not metabolized in vivo and is eliminated primarily unchanged, via glomerular filtration. It is also excreted into the GI tract via both biliary and nonbiliary routes and may become inactive after chelation with faecal material.
5.3 Environmental properties
