Pharmacological properties

Pharmacotherapeutic group: antibacterials for systemic use, macrolides

ATC Vet Code: QJ01FA90

5.1 Pharmacodynamic properties

Tylosin is a macrolide antibiotic produced by a strain of Streptomyces fradiae. It exerts its antimicrobial effect by inhibiting protein synthesis of susceptible micro-organisms.

The tylosin spectrum of activity includes Gram-positive bacteria, some Gram – negative strains such as Pasteurella, and Mycoplasma spp.

5.2 Pharmacokinetic particulars

Absorption: tylosin reaches maximal blood levels between 1 and 3 hours after an oral dose.

Distribution: after oral doses were given to pigs, tylosin was found in all tissues between 30 minutes and 2 hours after administration, except for the brain and spinal cord. Compared to plasma levels clearly higher tissue concentrations have been observed.

Metabolism and excretion: most of the material excreted through the faeces consists of tylosin (factor A), relomycine (factor D) and dihydrodesmycosin.

Target species

Pigs.

Indications

Pigs: Treatment and metaphylaxis of clinical signs of porcine proliferative enteritis (porcine intestinal adenomatosis, proliferative hemorrhagic enteropathy, ileitis) associated with Lawsonia intracellularis when the disease has been diagnosed at the group level.

3

Dosage

Oral use.

For use in individual pigs on farms where only a small number of pigs are to receive the medicine. Larger groups should be treated with medicated feeding stuff containing the premix.

Individual pigs should receive 5000 IU tylosin per kg bodyweight, corresponding to 250 mg product/kg bodyweight, once a day for 3 weeks. This is achieved by thoroughly mixing the product into the daily ration for each individual pig. The required amount of product should be added to the estimated quantity of daily ration for each pig in a bucket or similar receptacle and thoroughly mixed. The product should only be added to dry non-pelleted feed.

To ensure a correct dosage, body weight should be determined as accurately as possible.

Should there be no clear response to treatment within 3 days the treatment approach should be reconsidered.

3

Contraindications

Do not use in cases of hypersensitivity to the active substance, to other macrolides or to any of the excipients.

Do not use where cross-resistance to other macrolides (MLS-resistance) is suspected.

Do not use in animals vaccinated with tylosin-sensitive vaccines either at the same time or within 1 week previously.

Do not use in animals with hepatic disorders.

Do not use in horses. Danger of inflammation of the cecum.

Warnings

Special precautions for use in animals

This product is only for administration in small quantities of feed for immediate consumption, to individual animals. Animals with acute infections may have a reduced feed intake and should be treated with a suitable injectable veterinary medicinal product first.

Due to likely variability (time, geographical) in susceptibility of bacteria for tylosin, bacteriological sampling and susceptibility testing are recommended. Inappropriate use of the veterinary medicinal product may increase the prevalence of bacteria resistant to Tylosin and other macrolides.

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

Tylosin may induce irritation. Macrolides, such a tylosin, may also cause hypersensitivity (allergy) following injection, inhalation, ingestion or contact with skin or eye. Hypersensitivity to tylosin may lead to cross reactions to other macrolides and vice versa. Allergic reactions to these substances may occasionally be serious and therefore direct contact should be avoided. To avoid exposure during mixing and handling of the veterinary medicinal product wear safety glasses, impervious gloves, and wear either a disposable half mask respirator conforming to European Standard EN149 or a non-disposable respirator to European Standard EN140 with a filter to EN143. Wash hands after use.

In the event of accidental skin contact, wash thoroughly with soap and water. In case of accidental eye contact, flush the eyes with plenty of clean, running water.

Do not handle the veterinary medicinal product if you are allergic to ingredients in the veterinary medicinal product.

If you develop symptoms following exposure, such as skin rash, you should seek medical advice and show the physician this warning. Swelling of the face, lips and eyes or difficulty in breathing are more serious symptoms and require urgent medical attention.
