Summary for the public


What is Aivlosin?

Aivlosin is available as a premix for medicated feeding stuff and as an oral powder for pigs, and as granules for use in drinking water for pigs, chickens and pheasants.

The premix is mixed into pig feed by an authorised feed mill and the resulting “medicated feeding stuff” is then distributed to the farmer to treat a large number of pigs. The oral powder is mixed into pig feed by the pig owner and is used to treat individual pigs. The granules are added to the drinking water system, either directly or after dilution into a stock solution.


What is Aivlosin used for?

Aivlosin is an antibiotic.

In pigs, it is used to treat or prevent a number of infectious diseases that are caused by bacteria that affect the lungs (i.e. Swine Enzootic Pneumonia) or the intestinal tract (Swine Dysentery or Porcine Proliferative Enteropathy). Aivlosin improves the health and weight of the animals, but may not eliminate completely the bacteria that caused lung infection.

In chickens and pheasants, it is used for lung infections caused by a bacterium Mycoplasma gallisepticum.


How does Aivlosin work?

The active substance of Aivlosin is tylvalosin (previous name: acetylisovaleryltylosin), an antibiotic of the macrolide group. It works by blocking the bacteria's ribosomes, the parts of the cell where proteins are produced, and inhibits the growth of bacteria.


How has Aivlosin been studied?

investigated in microbiological laboratories. The main clinical studies of the effectiveness of Aivlosin were carried out on farms in a number of countries in Europe as well as outside the EU.

The studies in pigs were carried out either in pigs already affected by the disease or in pigs who had been in contact with diseased animals on the same farm and, therefore, likely to develop the disease as well.

For the treatment of large numbers of pigs, Aivlosin was mixed into pig food by an authorised feed mill using the “premix for medicated feeding stuff”. In order to achieve a good mixture in a large volume of food, special mixing equipment is needed and the mixing is done in several steps. For the treatment of individual pigs or a small number of animals, the animal owner mixed the medicine into the pig feed.

In chickens, Aivlosin was used either to treat already diseased chickens or to help preventing an outbreak of the disease in very young chicks that hatched from eggs, which came from flocks where the disease is present. The medicine was given with the drinking water at a dosage of 25 mg per kg bodyweight for three consecutive days. In order to prevent an outbreak of the disease, chicks were treated in their first 3 days of life and treatment was repeated after about 2 weeks. During treatment, the birds did not receive any other water than the medicated drinking water. In pheasants Aivlosin was used to treat already diseased birds with the drinking water at a dosage of 25 mg per kg bodyweight for three consecutive days.


What benefit has Aivlosin shown during the studies?

The studies showed that pigs treated with Aivlosin lost less weight during the infection and showed less severe signs of disease than untreated animals. The treatment success with Aivlosin was similar to the effectiveness of other medicines of the same class authorised for such diseases in pigs.

Chickens and pheasants treated with Aivlosin showed less severe signs of disease than untreated animals. The effectiveness of Aivlosin was similar to that of other medicine of the same class already authorised for this disease in chickens. The treatment did not completely eliminate all bacteria in the respiratory system and some birds still showed the disease; however, the number of affected animals was significantly smaller than in an untreated group of birds.


What is the risk associated with Aivlosin?

Very ill pigs might not eat all the feed offered and therefore might get an insufficient amount of the medicine. Therefore, treatment via feed with Aivlosin is not recommended for these animals.

Since the composition of the pig feed might affect the effectiveness of Aivlosin, it should only be used in dry feed. The oral powder cannot properly be mixed into pellets and should therefore not be used in pelleted pig feed.

The medicated drinking water should be replaced every 24 hours.


What are the precautions for the person who gives the medicine or comes into contact with the animal?

Aivlosin might cause skin reactions in some people. People who had in the past skin reactions when handling Aivlosin or similar products, should avoid any contact with Aivlosin.

When mixing Aivlosin into feed or drinking water or handling the medicated feed or water, direct contact with eyes, skin and mouth should be avoided and protective equipment should be worn, e.g. overalls, gloves and face masks (respirator). Skin that has been in contact with Aivlosin or medicated feed or drinking water should be washed. Aivlosin should not be used in people. However, if Aivlosin is accidentally consumed by a person, the advice of a doctor should be sought immediately.


What is the time to allow before the animal can be slaughtered and the meat used for human consumption (withdrawal period)?

After the last administration of Aivlosin in the feed (pigs) or via drinking water (chickens and pheasants), animals should not be slaughtered for two days. Aivlosin should not be used in birds that lay eggs for human consumption. It should, therefore, not be used in laying birds or in the two weeks before hens are likely to start laying eggs for human consumption. After administration of Aivlosin via drinking water, pigs should not be slaughtered for one day.


Why has Aivlosin been approved?

The Committee for Medicinal Products for Veterinary Use (CVMP) concluded that the benefits of Aivlosin are greater than any risks when Aivlosin is mixed into animal feed or drinking water and then used as described in the package leaflet. The Committee recommended that Aivlosin should be given a marketing authorisation. The benefit-risk balance may be found in module 6 (Scientific Discussion document) of this EPAR.

CLINICAL PARTICULARS
4.1 Target species
Pigs
4.2 Indications for use, specifying the target species
Treatment and prevention of swine enzootic pneumonia caused by susceptible strains of
Mycoplasma hyopneumoniae in pigs. At the recommended dose, lung lesions and weight loss
are reduced but infection with Mycoplasma hyopneumoniae is not eliminated.
Treatment of porcine proliferative enteropathy (ileitis) caused by Lawsonia intracellularis in

pathology results.
Treatment of clinical outbreaks of swine dysentery, caused by Brachyspira hyodysenteriae in
herds where the disease has been diagnosed and prevention of further clinical cases.
4.3 Contraindications
None.
4.4 Special warnings
Acute cases and severely diseased pigs with reduced food or water intake should be treated with a
suitable injectable product.
Generally, strains of B. hyodysenteriae have higher MIC values in cases of resistance against other
macrolides, such as tylosin. The clinical relevance of this reduced susceptibility is not fully explored.
Cross-resistance between tylvalosin and other macrolides cannot be excluded.
2
4.5 Special precautions for use
Special precautions for use in animals
It is sound clinical practice to base treatment 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 target bacteria.
Use of the product deviating from the instructions in the SPC may increase the risk of development
and selection of resistant bacteria and decrease the effectiveness of treatment with other macrolides
due to the potential for cross-resistance.
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Because Aivlosin has been shown to cause hypersensitivity reactions in laboratory animals, people
with known hypersensitivity to tylvalosin tartrate should avoid any contact with the product.
When mixing the veterinary medicinal product and handling the medicated feed, direct contact with
eyes, skin and mucous membranes should be avoided. Personal protective equipment should be worn
when mixing the veterinary medicinal product or handling the medicated feed: overalls, impervious
gloves and either a disposable half-mask respirator conforming to European Standard EN 149 or a
non-disposable respirator conforming to European Standard EN 140, with a filter to European
Standard EN 143. Wash contaminated skin.
In case of accidental ingestion seek medical advice immediately and show the label to the physician.
4.6 Adverse reactions (frequency and seriousness)
None known.
4.7 Use during pregnancy, lactation or lay
The safety of Aivlosin during pregnancy and lactation has not been established in pigs. Use only in
accordance with risk/benefit assessment by the responsible veterinarian.
Studies in laboratory animals have not produced any evidence of teratogenicity. Maternal toxicity in
rodents has been observed at doses of 400 mg tylvalosin per kg bodyweight and above. In mice, a
slight reduction in the foetal bodyweight was seen at doses causing maternal toxicity.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
In-feed use.
For incorporation into dry feed only.
For treatment and prevention of Swine Enzootic Pneumonia
The dosage is 2.125 mg tylvalosin per kg bodyweight per day in-feed for 7 consecutive days.
Secondary infection by organisms such as Pasteurella multocida and Actinobacillus
pleuropneumoniae may complicate enzootic pneumonia and require specific medication.
For treatment of Porcine Proliferative Enteropathy (ileitis)
The dosage is 4.25 mg tylvalosin per kg bodyweight per day in-feed for 10 consecutive days.

In older pigs, or in pigs with reduced appetite, or on restricted feed intake, inclusion levels may need
to be increased to achieve target dosage. Where feed intake is reduced, use the following formula:
Kg Premix/tonne feed =
Dose rate (mg/kg bodyweight) x bodyweight (kg)
Daily feed intake (kg) x Premix strength (mg/g)
As an adjunct to medication, good management and hygiene practices should be introduced in order to
reduce the risk of infection and to control the build up of resistance.
A horizontal ribbon mixer should be used to incorporate the product into the feeding stuff. It is
recommended that Aivlosin is first mixed into 10 kg of the feeding stuff, followed by the rest of the
feeding stuff and mixed well. Medicated feed may then be pelleted. Pelleting conditions involve a
single pre-conditioning step with steam for 5 minutes and pelleting at not more than 70 C under
normal conditions.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
No signs of intolerance have been observed in growing pigs at up to 10 times the recommended
dosage.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Macrolide antibiotic, ATCvet code: QJ01FA92.
5.1 Pharmacodynamic properties
Tylvalosin tartrate is a macrolide antibiotic that has antibacterial activity against Gram-positive, some
Gram-negative organisms and mycoplasma. It acts by inhibiting protein synthesis in the bacteria cell.
Macrolide antibiotics are the metabolites or semi-synthetic derivatives of metabolites of soil organisms
obtained by fermentation. They have different sized lactone rings and due to the dimethylamino group,
are basic. Tylvalosin has a sixteen membered ring.
Macrolides interfere with protein synthesis by reversibly binding to the 50S ribosome subunit. They
bind to the donor site and prevent the translocation necessary for keeping the peptide chain growing.
Their effect is essentially confined to rapidly dividing organisms. Macrolides are generally considered
bacteriostatic and mycoplasmastatic.
4
 
It is considered that there are multiple mechanisms responsible for resistance development to
macrolide compounds: namely alteration of the ribosomal target site, utilisation of active efflux
mechanism and production of inactivating enzymes.
Resistance to tylvalosin by Mycoplasma hyopneumoniae and Lawsonia intracellularis has not been
reported or found in the field to date. No breakpoint for Brachyspira hyodysenteriae has been
established.
Generally strains of B. hyodysenteriae have higher MIC values in cases of resistance against other
macrolides, such as tylosin. The clinical relevance of this reduced susceptibility is not fully explored.
Cross-resistance between tylvalosin and other macrolide antibiotics cannot be excluded.
5.2 Pharmacokinetic particulars
Tylvalosin tartrate is rapidly absorbed after oral administration of Aivlosin.
After administration of the recommended dose lung concentrations of 0.060–0.066 µg/ml were found
at 2 and 12 hours post-treatment. The parent compound is widely distributed in the tissues with the
highest concentrations found in the lungs, bile, intestinal mucosa, spleen, kidney and liver.
There is evidence that the concentration of macrolides is higher at the site of infection than in plasma,
in particular in neutrophils, alveolar macrophages and alveolar epithelial cells.
In vitro metabolism studies have confirmed that the parent compound is rapidly metabolised to 3-O-
acetyltylosin. In a trial with 14 C Aivlosin administered at 2.125 mg/kg to pigs for 7 days over 70 % of
the dose was excreted in the faeces, with urinary excretion accounting for 3 to 4 % of the dose.

4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
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.
For treatment and prevention of Enzootic Pneumonia
The dosage is 2.125 mg tylvalosin per kg bodyweight per day for 7 consecutive days.
Secondary infection by organisms such as Pasteurella multocida and Actinobacillus
pleuropneumoniae may complicate enzootic pneumonia and require specific medication.
For treatment of Porcine Proliferative Enteropathy (ileitis)
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
For treatment and prevention of Swine Dysentery
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
This is achieved by thoroughly mixing Aivlosin 8.5 mg/g oral powder into the daily ration for each
individual pig. Scoops of 3 sizes are provided for measuring the correct amount of Aivlosin 8.5 mg/g
oral powder for mixing with the daily ration, according to the schedule below. The feed containing the
oral powder should be provided as the sole ration for the periods recommended above.
13
The pig to be treated should be weighed and the amount of feed that the pig is likely to consume
should be estimated, based on a daily feed intake equivalent to 5 % of bodyweight. Consideration must
be given to pigs whose daily feed intake is reduced or restricted. The correct quantity of Aivlosin
8.5 mg/g oral powder 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.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Macrolide antibiotic, ATCvet code: QJ01FA92.
5.1 Pharmacodynamic properties
Tylvalosin tartrate is a macrolide antibiotic that has antibacterial activity against Gram-positive, some
Gram-negative organisms and mycoplasma. It acts by inhibiting protein synthesis in the bacteria cell.
Macrolide antibiotics are the metabolites or semi-synthetic derivatives of metabolites of soil organisms
obtained by fermentation. They have different sized lactone rings and due to the dimethylamino group,
are basic. Tylvalosin has a sixteen membered ring.
Macrolides interfere with protein synthesis by reversibly binding to the 50S ribosome subunit. They
bind to the donor site and prevent the translocation necessary for keeping the peptide chain growing.
Their effect is essentially confined to rapidly dividing organisms. Macrolides are generally considered
bacteriostatic and mycoplasmastatic.
14
It is considered that there are multiple mechanisms responsible for resistance development to
macrolide compounds: namely alteration of the ribosomal target site, utilisation of active efflux
mechanism and production of inactivating enzymes.
Resistance to tylvalosin by Mycoplasma hyopneumoniae and Lawsonia intracellularis has not been
reported or found in the field to date. No breakpoint for Brachyspira hyodysenteriae has been
established. Generally, strains of B. hyodysenteriae have higher MIC values in cases of resistance
against other macrolides, such as tylosin. The clinical relevance of this reduced susceptibility is not
fully explored.
Cross-resistance between tylvalosin and other macrolide antibiotics cannot be excluded.
5.2 Pharmacokinetic particulars
Tylvalosin tartrate is rapidly absorbed after oral administration of Aivlosin.
After administration of the recommended dose lung concentrations of 0.060–0.066 µg/ml were found
at 2 and 12 hours post-treatment. The parent compound is widely distributed in the tissues with the
highest concentrations found in the lungs, bile, intestinal mucosa, spleen, kidney and liver.
There is evidence that the concentration of macrolides is higher at the site of infection than in plasma,
in particular in neutrophils, alveolar macrophages and alveolar epithelial cells.
In vitro metabolism studies have confirmed that the parent compound is rapidly metabolised to 3-O-
acetyltylosin. In a trial with 14 C Aivlosin administered at 2.125 mg/kg to pigs for 7 days over 70 % of
the dose was excreted in the faeces, with urinary excretion accounting for 3 to 4 % of the dose.

CLINICAL PARTICULARS
4.1 Target species
Chickens
4.2 Indications for use, specifying the target species
Treatment and prevention of respiratory disease associated with Mycoplasma gallisepticum in
chickens.
As an aid in the prevention strategy to reduce the clinical signs and mortality from respiratory disease
in flocks, where infection in ovum with Mycoplasma gallisepticum is likely because the disease is
known to exist in the parent generation. The prevention strategy should include efforts to eliminate the
infection from the parent generation.
4.3 Contraindications
None.
4.4 Special warnings
None.
4.5 Special precautions for use
Special precautions for use in animals
Good management and hygiene practices should be introduced to reduce the risk of re-infection.
It is sound clinical practice to base treatment 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 target bacteria.
Use of the product deviating from the instructions in the SPC may increase the risk of development
and selection of resistant bacteria and decrease the effectiveness of treatment with other macrolides
due to the potential for cross-resistance.
17
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Tylvalosin has been shown to cause hypersensitivity reactions in laboratory animals; therefore, people
with known hypersensitivity to tylvalosin tartrate should avoid contact with the veterinary medicinal
product.
When mixing the veterinary medicinal product and handling the medicated water, direct contact, with
eyes, skin and mucous membranes should be avoided. Personal protective equipment consisting of
impervious gloves and a half-mask respirator conforming to European Standard EN 149 or a non-
disposable respirator conforming to European Standard EN 140, with a filter conforming to European
Standard EN 143 should be worn when mixing the veterinary medicinal product. Wash contaminated
skin.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the
label to the physician.
4.6 Adverse reactions (frequency and seriousness)
None known.
4.7 Use during pregnancy, lactation or lay
The safety of the veterinary medicinal product has not been established during lay.
4.8 Interaction with other medicinal products and other forms of interaction
None known.
4.9 Amounts to be administered and administration route
For use in drinking water.
For treatment of respiratory disease associated with Mycoplasma gallisepticum:
The dosage is 25 mg tylvalosin per kg bodyweight per day in drinking water for 3 consecutive days.
When used as an aid in the prevention strategy (where infection in ovum with Mycoplasma
gallisepticum is likely):
The dosage is 25 mg tylvalosin per kg bodyweight per day in drinking water for 3 consecutive days at
1 day old. This is followed by a second treatment with 25 mg tylvalosin per kg bodyweight per day in
drinking water for 3 consecutive days at the period of risk, i.e. at times of management stress such as
administration of vaccines (typically when birds are 2–3 weeks old).
Determine the combined bodyweight (in kg) of all the chickens to be treated. Select the correct
number of sachets according to the amount of product required.
One sachet of 40 g is sufficient to treat a total of 1,000 kg of chickens (e.g. 20,000 birds with an
average bodyweight of 50 g).
One sachet of 400 g is sufficient to treat a total of 10,000 kg of chickens (e.g. 20,000 birds with an
average bodyweight of 500 g).
In order to achieve a correct dose, the preparation of a concentrated (stock) solution might be required
(e.g. to treat a total of 500 kg total bird weight, only 50 % of the prepared stock solution prepared from
the 40 g sachet should be used).
18
The product should be added to a volume of water that the chickens will consume in one day. No other
source of drinking water should be available during the medication period.
Mixing instructions:
The product may be mixed directly into the drinking water system or first mixed as a stock solution
into a smaller amount of water, which is then added into the drinking water system.
When mixing the product directly into the drinking water system, the contents of the sachet should be
sprinkled onto the surface of the water and mixed thoroughly until a clear solution is produced
(usually within 3 minutes).
When preparing a stock solution the maximum concentration should be 40 g per 1,500 ml or 400 g of
product per 15 litres and it is necessary to mix the solution for 10 minutes. After this time, any
remaining cloudiness will not affect efficacy of the product.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
No signs of intolerance have been observed in chickens at up to 150 mg tylvalosin per kg bodyweight
per day for 5 days.
4.11 Withdrawalperiod(s)
Meat and offal: 2 days.
Not authorised for use in laying birds producing eggs for human consumption. Do not use within
14 days of onset of the laying.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Macrolide antibiotic, ATCvet code: QJ01FA92.
5.1 Pharmacodynamic properties
Tylvalosin is a macrolide antibiotic. Macrolides are metabolites or derivatives of metabolites of soil
organisms obtained by fermentation. They interfere with protein synthesis by reversibly binding to the
50S ribosome subunit. They are generally considered bacteriostatic.
Tylvalosin has activity against pathogenic organisms isolated from a range of animal species-mainly
Gram-positive organisms and mycoplasma but also some Gram-negative organisms. Tylvalosin has
activity against the following mycoplasma species found in chickens: Mycoplasma gallisepticum .
The Minimum Inhibitory Concentration (MIC) of tylvalosin for M. gallisepticum ranges from 0.007 to
0.25 µg/ml. Macrolides (including tylvalosin) have been shown to have effects on the innate immune
system, which may augment the direct effects of the antibiotic on the pathogen and aid the clinical
situation.
Bacteria can develop resistance to antimicrobial substances. There are multiple mechanisms
responsible for resistance development to macrolide compounds.
Cross-resistance within the macrolide group of antibiotics cannot be excluded. Reduced susceptibility
for tylvalosin was generally noted in tylosin resistant strains.
19
5.2 Pharmacokinetic particulars
Tylvalosin tartrate is rapidly absorbed after oral administration of the product. Tylvalosin is widely
distributed in tissues with the highest concentrations found in the respiratory tissues, bile, intestinal
mucosa, spleen, kidney and liver.
Tylvalosin has been shown to concentrate in phagocytic cells and gut epithelial cells. Concentrations
(up to 12x) were achieved in the cells (intracellular), compared to the extracellular concentration. In
vivo studies have shown tylvalosin to be present in higher concentrations in the mucous lining of the
respiratory and gut tissues compared to the plasma.
The major metabolite of tylvalosin is 3-acetyltylosin (3-AT), which is also microbiologically active.
The terminal half-lifes for the elimination of tylvalosin and its active metabolite 3-AT range from 1 to
1.45 hours. Six hours after treatment, the concentration of tylvalosin in the gastrointestinal tract
mucosa has a mean concentration of 133 ng/g and in the gastrointestinal contents of 1,040 ng/g. The
active metabolite 3-AT has a mean concentration of 57.9 ng/g and 441 ng/g, respectively.

CLINICAL PARTICULARS
4.1 Target species
Pigs
4.2 Indications for use, specifying the target species
Treatment and prevention of swine enzootic pneumonia caused by susceptible strains of
Mycoplasma hyopneumoniae in pigs. At the recommended dose, lung lesions and weight loss
are reduced but infection with Mycoplasma hyopneumoniae is not eliminated.
Treatment of porcine proliferative enteropathy caused by Lawsonia intracellularis in herds
where there is a diagnosis based on clinical history, post-mortem findings and clinical
pathology results.
Treatment of clinical outbreaks of swine dysentery, caused by Brachyspira hyodysenteriae in
herds where the disease has been diagnosed and prevention of further clinical cases.
4.3 Contraindications
None.
4.4 Special warnings
Acute cases and severely diseased pigs with reduced food and water intake should be treated with a
suitable injectable veterinary medicinal product.
Generally, strains of B. hyodysenteriae have higher MIC values in cases of resistance against other
macrolides such as tylosin. The clinical relevance of this reduced susceptibility is not fully explored.
Cross-resistance between tylvalosin and other macrolides cannot be excluded.
4.5 Special precautions for use
Special precautions for use in animals
It is sound clinical practice to base treatment on susceptibility testing.
32
Special precautions to be taken by the person administering the veterinary medicinal product to
animals
Because the veterinary medicinal product has been shown to cause hypersensitivity reactions in
laboratory animals, people with known hypersensitivity to tylvalosin tartrate should avoid any contact
with the veterinary medicinal product.
When adding the veterinary medicinal product to the individual feed ration and when handling this
medicated feed, direct contact with eyes, skin and mucous membranes should be avoided. Personal
protective equipment should be worn when handling the veterinary medicinal product or the feed with
the veterinary medicinal product added: overalls, impervious gloves and either a disposable half-mask
respirator conforming to European Standard EN 149 or a non-disposable respirator conforming to
European Standard EN 140, with a filter to European Standard EN 143. Wash contaminated skin.
In case of accidental ingestion seek medical advice immediately and show the label to the physician.
4.6 Adverse reactions (frequency and seriousness)
None known.
4.7 Use during pregnancy, lactation or lay
The safety of Aivlosin during pregnancy and lactation has not been established in pigs. Use only in
accordance with risk/benefit assessment by the responsible veterinarian.
Studies in laboratory animals have not produced any evidence of teratogenicity. Maternal toxicity in
rodents has been observed at doses of 400 mg tylvalosin per kg bodyweight and above. In mice, a
slight reduction in the foetal bodyweight was seen at doses causing maternal toxicity.
4.8 Interaction with other medicinal products and other forms of interaction
Cross-resistance to other macrolide antibiotics cannot be excluded.
4.9 Amounts to be administered and administration route
For use in individual pigs on farms where only a small number of pigs are to receive the treatment.
Larger groups should be treated with medicated feeding stuff containing the premix.
For treatment and prevention of Swine Enzootic Pneumonia
The dosage is 2.125 mg tylvalosin per kg bodyweight per day for 7 consecutive days.
Secondary infection by organisms such as Pasteurella multocida and Actinobacillus
pleuropneumoniae may complicate enzootic pneumonia and require specific medication.
For treatment of Porcine Proliferative Enteropathy (ileitis)
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
For treatment and prevention of Swine Dysentery
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
This is achieved by thoroughly mixing Aivlosin into approximately 200–500 g of feed and then
thoroughly mixing this pre-mixture into the remainder of the daily ration.
Scoops of 2 sizes are provided for measuring the correct amount of Aivlosin for mixing with the daily
ration, according to the schedule below. The feed containing the oral powder should be provided as the
sole ration for the periods recommended above.
33
The pig to be treated should be weighed and the amount of feed that the pig is likely to consume
should be estimated, based on a daily feed intake equivalent to 5 % of bodyweight. Consideration must
be given to pigs whose daily feed intake is reduced or restricted. The correct quantity of Aivlosin
should be added to the estimated quantity of daily ration for each pig, in a bucket or similar receptacle,
and thoroughly mixed.
The veterinary medicinal product should only be added to dry non-pelleted feed.

PHARMACOLOGICAL PROPERTIES
Pharmacotherapeutic group: Macrolide antibiotic, ATCvet code: QJ01FA92.
5.1 Pharmacodynamic properties
Tylvalosin tartrate is a macrolide antibiotic that has antibacterial activity against Gram-positive, some
Gram-negative organisms and mycoplasma. It acts by inhibiting protein synthesis in the bacteria cell.
Macrolide antibiotics are the metabolites or semi-synthetic derivatives of metabolites of soil organisms
obtained by fermentation. They have different sized lactone rings and due to the dimethylamino group,
are basic. Tylvalosin has a sixteen membered ring.
Macrolides interfere with protein synthesis by reversibly binding to the 50S ribosome subunit. They
bind to the donor site and prevent the translocation necessary for keeping the peptide chain growing.
Their effect is essentially confined to rapidly dividing organisms. Macrolides are generally considered
bacteriostatic and mycoplasmastatic.
34
It is considered that there are multiple mechanisms responsible for resistance development to
macrolide compounds: namely alteration of the ribosomal target site, utilisation of active efflux
mechanism and production of inactivating enzymes.
Resistance to tylvalosin by Mycoplasma hyopneumoniae and Lawsonia intracellularis has not been
reported or found in the field to date. No breakpoint for Brachyspira hyodysenteriae has been
established. Generally, strains of B. hyodysenteriae have higher MIC values in cases of resistance
against other macrolides, such as tylosin. The clinical relevance of this reduced susceptibility is not
fully explored.
Cross-resistance between tylvalosin and other macrolide antibiotics cannot be excluded.
5.2 Pharmacokinetic particulars
Tylvalosin tartrate is rapidly absorbed after oral administration of Aivlosin.
After administration of the recommended dose lung concentrations of 0.060–0.066 µg/ml were found
at 2 and 12 hours post-treatment. The parent compound is widely distributed in the tissues with the
highest concentrations found in the lungs, bile, intestinal mucosa, spleen, kidney and liver.
There is evidence that the concentration of macrolides is higher at the site of infection than in plasma,
in particular in neutrophils, alveolar macrophages and alveolar epithelial cells.
In vitro metabolism studies have confirmed that the parent compound is rapidly metabolised to 3-O-
acetyltylosin. In a trial with 14 C Aivlosin administered at 2.125 mg/kg to pigs for 7 days over 70 % of
the dose was excreted in the faeces, with urinary excretion accounting for 3 to 4 % of the dose.

Mycoplasma hyopneumoniae . At the recommended dose, lung lesions and weight loss are
reduced but infection with Mycoplasma hyopneumoniae is not eliminated.
Treatment of porcine proliferative enteropathy (ileitis) caused by Lawsonia intracellularis in
herds where there is a diagnosis based on clinical history, post-mortem findings and clinical
pathology results.
Treatment of clinical outbreaks of swine dysentery in herds, caused by Brachyspira
hyodysenteriae, where the disease has been diagnosed, and prevention of further clinical
cases.

DOSAGE FOR EACH SPECIES, ROUTE AND METHOD OF ADMINISTRATION
In-feed use.
For incorporation into dry feed only.
For treatment and prevention of Swine Enzootic Pneumonia:
The dosage is 2.125 mg tylvalosin per kg bodyweight per day in-feed for 7 consecutive days.
Secondary infection by organisms such as Pasteurella multocida and Actinobacillus
pleuropneumoniae may complicate enzootic pneumonia and require specific medication.
For treatment of Porcine Proliferative Enteropathy (ileitis):
The dosage is 4.25 mg tylvalosin per kg bodyweight per day in-feed for 10 consecutive days.
For treatment and prevention of Swine Dysentery:
The dosage is 4.25 mg tylvalosin per kg bodyweight per day in-feed for 10 consecutive days.

* Important : these inclusion rates assume a pig eats equivalent of 5 % bodyweight per day.
In older pigs, or in pigs with reduced appetite, or on restricted feed intake, inclusion levels may need
to be increased to achieve target dosage. Where feed intake is reduced, use the following formula:
Kg Premix/tonne feed =
Dose rate (mg/kg bodyweight) x bodyweight (kg)
Daily feed intake (kg) x Premix strength (mg/g)
Acute cases and severely diseased pigs with reduced food and water intake should be treated with a
suitable injectable product.
In addition to medical treatment, good management and hygiene practices should be established on the
farm in order to reduce the risk of infection and to control the build up of resistance.
The medicated feed should be fed as the sole ration.
9.
ADVICE ON CORRECT ADMINISTRATION
Mixing Instructions
A horizontal ribbon mixer should be used to incorporate the product into feeding stuff. It is
recommended that Aivlosin is first mixed with 10 kg of the feeding stuff, followed by the rest of the
62
 
feeding stuff and mixed well. Medicated feed may then be pelleted. Pelleting conditions involve a
single pre-conditioning step with steam for 5 minutes and pelleting at not more than 70 C under
normal conditions.
No known incompatibilities.
10. WITHDRAWAL PERIOD
Meat and offal: 2 days.
11. SPECIAL STORAGE PRECAUTIONS
Keep out of the reach and sight of children.
Store below 30 °C.
Keep the container tightly closed.
Store in the original container.
Do not use after the expiry date stated on the label.
Shelf life after incorporation into feed: meal and pellets: 1 month.
12. SPECIAL WARNINGS
Because Aivlosin has been shown to cause hypersensitivity reactions in laboratory animals, people
with known hypersensitivity to tylvalosin tartrate should avoid any contact with the product.
When mixing the veterinary medicinal product and handling the medicated feed, direct contact with
eyes, skin and mucous membranes should be avoided. Personal protective equipment should be worn
when mixing the veterinary medicinal product or handling the medicated feed: overalls, impervious
gloves and either a disposable half-mask respirator conforming to European Standard EN 149 or a
non-disposable respirator conforming to European Standard EN 140, with a filter to EN 143. Wash
contaminated skin.
In case of accidental ingestion seek medical advice immediately and show the label to the physician.
The safety of Aivlosin during pregnancy and lactation has not been established in pigs. Use only in
accordance with risk/benefit assessment by the responsible veterinarian. Studies in laboratory animals
have not produced any evidence of teratogenicity. Maternal toxicity in rodents has been observed at
doses of 400 mg tylvalosin per kg bodyweight and above. In mice, a slight reduction in the foetal
bodyweight was seen at doses causing maternal toxicity.
It is sound clinical practice to base treatment 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 target bacteria.
Use of the product deviating from the instructions may increase the risk of development and selection
of resistant bacteria and decrease the effectiveness of treatment with other macrolides due to the
potential for cross-resistance.
Generally, strains of B. hyodysenteriae have higher MIC values in cases of resistance against other
macrolides, such as tylosin. The clinical relevance of this reduced susceptibility is not fully explored.
Cross-resistance between tylvalosin and other macrolides cannot be excluded.

13. SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE
MATERIALS, IF ANY
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal
products should be disposed of in accordance with local requirements.

ADVICE ON CORRECT ADMINISTRATION
The oral powder is 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.
For treatment and prevention of Swine Enzootic Pneumonia
The dosage is 2.125 mg tylvalosin per kg bodyweight per day in-feed for 7 consecutive days.
Secondary infection by organisms such as Pasteurella multocida and Actinobacillus
pleuropneumoniae may complicate enzootic pneumonia and require specific medication.
For treatment of Porcine Proliferative Enteropathy (ileitis)
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
For treatment and prevention of Swine Dysentery
The dosage is 4.25 mg tylvalosin per kg bodyweight per day for 10 consecutive days.
This is achieved by thoroughly mixing Aivlosin 8.5 mg/g oral powder into the daily ration for each
individual pig. Scoops of 3 sizes are provided for measuring the correct amount of Aivlosin 8.5 mg/g
oral powder for mixing with the daily ration, according to the schedule below. The feed containing the
oral powder should be provided as the sole ration for the periods recommended above.
The pig to be treated should be weighed and the amount of feed that the pig is likely to consume
should be estimated, based on a daily feed intake equivalent to 5 % of bodyweight. Consideration must
be given to pigs whose daily feed intake is reduced or restricted. The correct quantity of Aivlosin 8.5
mg/g oral powder should then 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.

Acute cases and severely diseased pigs with reduced food or water intake should be treated with a
suitable injectable product.
In addition to medical treatment, good management and hygiene practices should be established on the
farm in order to reduce the risk of infection and to control the potential development of resistance.
10. WITHDRAWAL PERIOD
Meat and offal: 2 days.
11. SPECIAL STORAGE PRECAUTIONS
Keep out of the reach and sight of children.
Do not store above 25 °C.
Keep the container tightly closed.
Store in the original container.
Do not use after the expiry date stated on the label.
Feed to which the oral powder has been added should be replaced if not consumed within 24 hours.
12. SPECIAL WARNINGS
Because Aivlosin has been shown to cause hypersensitivity reactions in laboratory animals people
with known hypersensitivity to tylvalosin tartrate should avoid any contact with the product.
When adding the veterinary medicinal product to the individual feed ration and when handling this
feed, direct contact with eyes, skin and mucous membranes should be avoided. Personal protective
equipment should be worn when handling the veterinary medicinal product or the feed with product
added: overalls, impervious gloves and either a disposable half-mask respirator conforming to
European Standard EN 149 or a non-disposable respirator conforming to European Standard EN 140,
with a filter to EN 143. Wash contaminated skin.
In case of accidental ingestion seek medical advice immediately and show the label to the physician.
The safety of Aivlosin during pregnancy and lactation has not been established in pigs. Use only in
accordance with risk/benefit assessment by the responsible veterinarian. Studies in laboratory animals
have not produced any evidence of teratogenicity. Maternal toxicity in rodents has been observed at
doses of 400 mg tylvalosin per kg bodyweight and above. In mice, a slight reduction in the foetal
bodyweight was seen at doses causing maternal toxicity.
It is sound clinical practice to base treatment 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 target bacteria.
Use of the product deviating from the instructions may increase the risk of development and selection
of resistant bacteria and decrease the effectiveness of treatment with other macrolides due to the
potential for cross-resistance.
Cross-resistance to other macrolide antibiotics cannot be excluded.

13. SPECIAL PRECAUTIONS FOR THE DISPOSAL OF UNUSED PRODUCT OR WASTE
MATERIALS, IF ANY
Any unused veterinary medicinal product or waste materials derived from such veterinary medicinal

TARGET SPECIES
Chickens.
8.
DOSAGE FOR EACH SPECIES, ROUTE AND METHOD OF ADMINISTRATION
For use in drinking water.
For treatment of respiratory disease associated with Mycoplasma gallisepticum:
The dosage is 25 mg tylvalosin per kg bodyweight per day in drinking water for 3 consecutive days.
When used as an aid in the prevention strategy (where infection in ovum with Mycoplasma
gallisepticum is likely):
The dosage is 25 mg tylvalosin per kg bodyweight per day in drinking water for 3 consecutive days at
1 day old. This is followed by a second treatment with 25 mg tylvalosin per kg bodyweight per day in
drinking water for 3 consecutive days at the period of risk, i.e. at times of management stress such as
administration of vaccines (typically when birds are 2–3 weeks old).
Determine the combined bodyweight (in kg) of all the chickens to be treated. Select the correct
number of sachets according to the amount of product required.
One sachet of 40 g is sufficient for a total of 1,000 kg of chickens (e.g. 20,000 birds with an average
bodyweight of 50 g). One sachet of 400 g is sufficient to treat a total of 10,000 kg of chickens (e.g.
20,000 birds with an average bodyweight of 500 g).
In order to achieve a correct dose, the preparation of a concentrated (stock) solution might be required
(e.g. to treat a total of 500 kg total bird weight, only 50 % of the prepared stock solution prepared from
the 40 g sachet should be used).
The product should be added to a volume of water that the chickens will consume in one day. No other
source of drinking water should be available during the medication period.
9.
ADVICE ON CORRECT ADMINISTRATION
The product may be mixed directly into the drinking water system or first mixed as a stock solution
into a smaller amount of water, which is then added into the drinking water system.
When mixing the product directly into the drinking water system, the contents of the sachet should be
sprinkled onto the surface of the water and mixed thoroughly until a clear solution is produced
(usually within 3 minutes).
When preparing a stock solution the maximum concentration should be 40 g per 1,500 ml or 400 g of
product per 15 litres and it is necessary to mix the solution for 10 minutes. After this time, any
remaining cloudiness will not affect the efficacy of the veterinary medicinal product.
80
10. WITHDRAWAL PERIOD
Meat and offal: 2 days.
Not authorised for use in laying birds producing eggs for human consumption. Do not use within 14
days of onset of the laying.
11. SPECIAL STORAGE PRECAUTIONS
Keep out of the reach and sight of children.
Do not store above 30 C.
Opened sachets should not be stored.
Do not use after the expiry date, which stated on the label as “EXP”.
Shelf-life of the medicated drinking water: 24 hours.
Only a sufficient amount of medicated drinking water should be prepared to cover the daily requirements.
Medicated drinking water should be replaced every 24 hours.
12. SPECIAL WARNINGS
Good management and hygiene practices should be introduced in order to reduce the risk of re-
infection.
It is sound clinical practice to base treatment 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 target bacteria.
Use of the product deviating from the instructions may increase the risk of development and selection
of resistant bacteria and decrease the effectiveness of treatment with other macrolides due to the
potential for cross-resistance.
Tylvalosin has been shown to cause hypersensitivity reactions in laboratory animals; therefore, people
with known hypersensitivity to tylvalosin tartrate should avoid contact with the veterinary medicinal
product.
When mixing the veterinary medicinal product and handling the medicated water, direct contact, with
eyes, skin and mucous membranes should be avoided. Personal protective equipment should
consisting of impervious gloves and a half-mask respirator conforming to European Standard EN 149
or a non-disposable respirator conforming to European Standard EN 140, with a filter conforming to
European Standard EN 143 be worn when mixing the veterinary medicinal product. Wash
contaminated skin.
In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the
label to the physician.
