SUMMARY OF PRODUCT CHARACTERISTICS
NAME OF THE VETERINARY MEDICINAL PRODUCT
Tetramin 200 Powder Premix for Medicated Feed
QUALITATIVE AND QUANTITATIVE COMPOSITION
Each kilogram contains 200 g oxytetracycline (as oxytetracycline dihydrate) in a limestone vehicle.
For full list of excipients, see section 6.1.
PHARMACEUTICAL FORM
Premix for medicated feed.
Mid to light brown or light yellow powder premix for incorporation into feedstuffs.
CLINICAL PARTICULARS
Target species
Pigs.
Indications for use, specifying the target species
For use as an aid in the control of respiratory diseases caused by bacteria sensitive to oxytetracycline.
Contraindications
None.
Special warnings for each target species
None.
Special precautions for use
Special precautions for use in animals
Long term use of this product may lead to development of bacterial resistance and is not recommended. However, the recommended course of treatment should be completed.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
If you know you are allergic to oxytetracycline, do not handle the product. When incorporating into feed, care should be taken not to inhale any dust when handling the product and skin contact should be avoided. It is recommended that a face mask, conforming to EN140 with a filter to EN143, be worn during the dispensing of the product. Hands and exposed skin should be washed thoroughly at the end of the operation.
Adverse reactions (frequency and seriousness)
None known.
Use during pregnancy, lactation or lay
Not applicable.
Interaction with other medicinal products and other forms of interaction
The presence of high concentrations of divalent or trivalent ions e.g. Ca2+, may reduce absorption of oxytetracycline due to formation of chelates with no antimicrobial activity. This is only a practical consideration in animals fed milk or milk replacer.
Amounts to be administered and administration route
20 mg/kg bodyweight per day in feed for 15 days.
The following inclusion rates may be used as a guide to obtaining this dose in normal and inappetant pigs.

To ensure thorough dispersion of the product, it should first be mixed with a suitable quantity of feed before incorporation in the final mix. If this product is incorporated in an intermediate feedingstuff, care should be taken to ensure that the intermediate feedingstuff is incorporated at a rate which will yield the same concentration of active ingredient as stated in the dosage schedule.
For incorporation into dry feed at the registered mill.
Overdose (symptoms, emergency procedures, antidotes), if necessary
The safety margin of oxytetracycline in the target species is very wide and toxic signs are unlikely to be seen.
Withdrawal period
Animals must not be slaughtered for human consumption during treatment. Pigs may be slaughtered for human consumption only after 5 days from the end of last treatment.
PHARMACOLOGICAL PROPERTIES
ATCVet Code:QJ01AA06
Oxytetracycline (OTC) is a broad-spectrum antibiotic. Its mode of action is bacteriostatic by inhibition of prokaryotic protein synthesis at the ribosomal level. It is active against Gram-positive and Gram-negative aerobic and anaerobic micro-organisms, Mycoplasmaspp., Chlamydiaspp., Leptospiraspp. and Rickettsias. It has little activity against Salmonellaspp., Escherichia coli, Enterobacter and Klebsiellaspp. and has essentially no activity against Pseudomonasspp., Proteusspp. and yeasts. Sub-Minimum Inhibitory Concentration (MIC) effects have been identified for tetracyclines. Inhibition of adhesion of pathogens to host cell surfaces are known to occur at levels of antibiotic lower than the MIC. Host cell adhesion is an essential pre-requisite for the expression of pathogenicity for several porcine respiratory pathogens e.g. Actinobacillus pleuropneumoniae, Bordetella brochisepticaand mycoplasmas.
Selected resistance to tetracyclines is not uncommon among bacteria and it is important that sensitivity is determined prior to initiation of therapy. Most organisms which are resistant to one member of the tetracycline group will have cross-resistance to other members of the group.
Due to the amphoteric nature of OTC, oral bioavailability is low (<10%). OTC has excellent distribution properties with a Volume of Distribution (Vd) exceeding 1.2 L/kg. The compound tends to concentrate in the lung, liver and kidney. OTC undergoes enterohepatic circulation. It does not appear to be metabolised to any significant degree. The compound is mainly excreted as the parent molecule primarily in the urine but also in the faeces.
