Pharmacological properties

Pharmacotherapeutic group: lincosamides, ATCvet code: QJ01FF02.

5.1 Pharmacodynamic properties

Lincomycin is a lincosamide antibiotic produced by Streptomyces lincolensis. Lincomycin is bacteriostatic in action inhibiting the protein synthesis predominantly by binding to the 50S ribosomal subunits of bacteria.

Depending on the sensitivity of micro-organisms, and on the concentration of the active substance the protein synthesis inhibition antibacterial action can either be bacteriostatic or bactericide.

Lincomycin is active against a wide range of Gram-positive bacteria, such as staphylococci, streptococci, β-haemolytic streptococci, corynebacteria, Erysipelothrix spp., and anaerobic bacteria, such as clostridia, Bacteroides spp., Brachyspira spp., as well as Leptospira spp. and Mycoplasma spp.

Lincomycin has no activity against Gram-negative bacteria, such as Klebsiella spp., Pasteurella spp., and Salmonella spp.

The resistance rate against lincomycin is slow, multiple-step type. Plasmid mediated infectious resistance is also described.

No cross-resistance has been described with penicillin, ampicillin, cephalosporins, tetracyclines, or novobiocin.

Lincomycin MIC90 (µg/ml) values are the followings:

Mycoplasma hyopneumoniae: MIC90 (µg/ml) = 0.25 Brachyspira hyodysenteriae: MIC90 (µg/ml) = 100

5.2 Pharmacokinetic particulars

Systemic bioavailability of lincomycin is approximately 53% after oral administration in pigs Lincomycin is rapidly absorbed orally and reaches therapeutic plasma concentration. After a single, oral administration of approximately 4.4 mg/kg and 11 mg/kg lincomycin to pigs resulted therapeutic plasma concentration for 12-16 hours, reaching peak plasma concentration after 4 hours. After a single, oral dose of 10 mg/kg lincomycin to pigs the maximum plasma concentration (Cmax) of 1.45 mg/kg was reached at 3.6 hours (Tmax). The elimination half life (T1/2β) is about 3.36 hours. The oral administration of 22 mg/kg lincomycin for 3 days to pigs did not result in drug accumulation after 24 hours of administration and there was no therapeutic plasma concentration.

After oral administration the absorbed lincomycin is eliminated through the bile and faeces in active form or as metabolites.

Lincomycin is also excreted in the milk.

Lincomycin reaches the inflammation site by polymorf neutrophil granulocytes that explains its fast absorption and distribution, efficient penetration and targeted activity in difficult to reach tissues.

Target species

Swine.

3

Indications

For treatment of swine dysentery caused by Brachyspira hyodysenteriae, mycoplasmal pneumonia associated with Mycoplasma hyopneumoniae and porcine proliferative enteropathy (ileitis) associated with Lawsonia intracellularis.

3

Dosage

To be administered orally, in dry medicated feeding stuff.

Treatment of swine dysentery:

Feed 110 mg lincomycin/kg complete feed (equivalent to 5.5 mg lincomycin/kg bodyweight) as the sole ration for three weeks or until clinical signs of disease (watery, mucoid or bloody stools) disappear.

Treatment of mycoplasmal pneumonia:

Feed 220 mg lincomycin/kg complete feed (equivalent to 11 mg lincomycin/kg bodyweight) as the sole ration for three weeks or until clinical signs of disease disappear.

Treatment of porcine proliferative enteropathy:

Feed 220 mg lincomycin/kg complete feed (equivalent to 11 mg lincomycin/kg bodyweight) as the sole ration for three weeks.

Medicated feed may be pelleted at temperatures not exceeding 85oC.

3

Contraindications

Do not use in case of hypersensitivity to the active substance or to any of the excipient. Do not use in horses, ruminants, rabbits, guinea pigs and hamsters.

Do not use if resistance to lincosamides has been detected.

3

Adverse reactions

Lincomycin may occasionally cause transient soft stools and/or mild swelling of the anus within the first two days of treatment. Very rarely some pigs may show skin reddening and mildly irritable behaviour. These conditions are usually self-correcting within 5-8 days without discontinuing lincomycin treatment.

Warnings

Special precautions for use in animals

Medicated feeding stuff uptake can be affected by the severity of the disease. In case of insufficient uptake of feed, animals should be treated parenterally.

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

People with known hypersensitivity to lincomycin should avoid contact with the veterinary medicinal product.

Care should be taken not to inhale any dust. The wearing of approved dust masks (either a disposable half-mask respirator conforming to European Standard EN 149 or a non-disposable respirator to European Standard EN 140 with a filter to EN 143), gloves, overalls and safety glasses is recommended during the handling and mixing of this product.

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