Key Features of  Eprizero Pour-on

Increase on milk production: Studies have shown that cattle treated with Eprizero can have an increase in their milk yield of up to 2 litres per animal per day.

Increased weight gain: Cattle treated with Eprizero have also been shown to graze for up to an hour longer every day. This leads to improved weight gain as well as improved milk yields.

Improved body conditions: The increase in grazing times leads also to an increase in the nutrients consumed by cattle. This increase in nutrients leads to healthier cattle with increased body conditions.

Improved fertility rates: The elimination of parasites and the improved overall health of the cattle will lead to increased fertility rates. Herds treated with Eprizero have shown increases of up to 20% in conception rates in the first year alone.

4.3 Contraindications

This product is formulated only for topical application to beef and dairy cattle, including lactating dairy cattle.
Do not
use in other animal species.
Do not administer orally or by injection.
Do not use in animals with known hypersensitivity to the active ingredient or any of the excipients.

4.4 Special warnings for each target species

The details provided in section 4.10 apply.
If there is a risk for re-infestation, the advice of a veterinarian should be sought regarding the need for and frequency of repeat administration.
Care should be taken to avoid the following practices because they increase the risk of development of resistance and could ultimately result in ineffective therapy:
- Too frequent and repeated use of anthelmintics from the same class, over an extended period of time.
- Underdosing, which may be due to underestimation of bodyweight, misadministration of the product, or lack of
  calibration of the dosing device (if any).

Suspected clinical cases of resistance to anthelmintics should be further investigated using appropriate tests (e.g. Faecal

Egg Count Reduction Test). Where the results of the test(s) strongly suggest resistance to a particular anthelmintic, an anthelmintic belonging to another pharmacological class and having a different mode of action should be used.

To date no resistance to eprinomectin (a macrocyclic lactone) has been reported within the EU.
However resistance to other macrocyclic lactones has been reported in parasite species in cattle within the EU. Therefore, use of this product should be based on local (regional, farm) epidemiological information about susceptibility of nematodes and recommendations on how to limit further selection for resistance to anthelmintics.

While mite and louse numbers decline rapidly following treatment, due to the feeding habits of the parasites, in some
cases several weeks may be required for complete eradication.
For effective use, the product should not be applied to areas of the backline covered with mud or manure.

4.5 Special precautions for use

i. Special precautions for use in animals

Not to be used in other species; avermectins can cause fatalities in dogs.
The product should be applied only to healthy skin.

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


This product may be irritating to human skin and eyes and may cause hypersensitivity.
Avoid skin and eye contact with the product during treatment and when handling recently treated animals.
Users should wear rubber gloves, boots and a waterproof coat when applying the product.
Should clothing become contaminated, remove as soon as possible and launder before re-use.
If accidental skin contact occurs, wash the affected area immediately with soap and water.
If accidental eye exposure occurs, flush eyes immediately with water.
This product may be toxic after accidental ingestion.
Avoid accidental ingestion of the product by hand to mouth contact.
Do not smoke, eat or drink while handling the product.
In the event of ingestion, wash out mouth with water and seek medical advice.
Wash hands after use.
This product is flammable. Keep away from sources of ignition.
Inhalation of the product may cause irritation.
Use only in well ventilated areas or outdoors.

iii. Other precautions

Eprinomectin is very toxic to dung fauna and aquatic organisms and may accumulate in sediments.
The risk to aquatic ecosystems and dung fauna can be reduced by avoiding too frequent and repeated use of
eprinomectin (and products of the same anthelmintic class) in cattle.
The risk to aquatic ecosystems will be further reduced by keeping treated cattle away from water bodies for two to four weeks after treatment.

4.6 Adverse reactions (frequency and seriousness)

No undesirable effects have been identified when the product is used at the recommended dose rate.

4.7 Use during pregnancy, lactation or lay

May be used in dairy cattle during all stages of lactation.
Studies have demonstrated a wide safety margin. Studies conducted at three times the recommended use level of 0.5 mg eprinomectin/kg b.w. had no adverse effect on breeding performance of cows or bulls.

4.8 Interaction with other medicinal products and other forms of interaction

None known.

4.9 Amounts to be administered and administration route

Administer only by topical application at the dose rate of 1 ml per 10 kg of body weight, corresponding to the
recommended dose rate of 0.5 mg eprinomectin per kg b.w. The product should be applied topically by pouring along
the backline in a narrow strip extending from the withers to the tailhead.

Rainfall at anytime before or after treatment will not affect the efficacy of the product.
To ensure administration of a correct dose, bodyweight should be determined as accurately as possible; accuracy of the dosing device (dosing cup or dosing gun delivery system) should be checked.

For best results use as part of a program to control both internal and external parasites of cattle based on the
epidemiology of these parasites.

4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary

In adult cattle, after administration of 5 times the recommended dose (2.5 mg eprinomectin/kg body weight), mild hair
loss was observed. No other signs of toxicity were seen.

No antidote has been identified.

4.11 Withdrawal Period(s)

Meat & offal: 10 days
Milk: zero hours.

5 PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES

Pharmacotherapeutic group:
Avermectins.

ATC Vet Code:

QP54AA04

5.1 Pharmacodynamic properties

Mode of action

Eprinomectin is a member of the macrocyclic lactone class of endectocides.
Compounds of the class bind selectively
and with high affinity to glutamate-gated chloride ion channels which occur in invertebrate nerve or muscle cells.
This leads to an increase in the permeability of the cell membrane to chloride ions with hyperpolarization of the nerve or muscle cell, resulting in paralysis and death of the parasite.
Compounds of this class may also interact with other ligand-gated chloride channels, such as those gated by the
neurotransmitter gamma-aminobutyric acid (GABA).
The margin of safety for compounds of this class is attributable to the fact that mammals do not have glutamate-gated
chloride channels; the macrocyclic lactones have a low affinity for other mammalian ligand-gated chloride channels,
and they do not readily cross the blood-brain barrier.

5.2 Pharmacokinetic properties

The bioavailability of topically applied eprinomectin in cattle is about 30% with most absorption occurring by about 10
days after treatment. Eprinomectin is not extensively metabolized in cattle following topical administration. In all
biological matrices, the B1a component of eprinomectin is the single most abundant residue.

Eprinomectin consists of the components B1a ( 90 %) and B1b ( 10 %) which differ by a methylene unit and is not
extensively metabolized in cattle. Metabolites amount to approximately 10% of the total residues in plasma, milk,
edible tissues and faeces.

The metabolism profile is nearly identical, qualitatively and quantitatively, in the above biological matrices and does
not change significantly with time after administration of eprinomectin. The percent contribution of B1a and B1b to the
overall metabolite profile remains constant. The ratio of the two drug components in the biological matrices is identical to that in the formulation demonstrating that the two eprinomectin components are metabolized with nearly equal rate constants. Since the metabolism and the tissue distribution of the two components are quite similar, the
pharmacokinetics of the two components would be also similar.
Eprinomectin is strongly linked to plasma proteins (99 %). Faeces is the major route of elimination.

5.3 Environmental properties

Like other macrocyclic lactones, eprinomectin has the potential to adversely affect non-target organisms. Following
treatment, excretion of potentially toxic levels of eprinomectin may take place over a period of several weeks. Faeces
containing eprinomectin excreted onto pasture by treated animals may reduce the abundance of dung feeding organisms which may impact on the dung degradation.
Eprinomectin is very toxic to aquatic organisms and may accumulate in sediments.

Areas of damaged skin should be avoided, as should areas contaminated with mud or manure

 

What is Eprinomectin?

Eprinomectin is a semi-synthetic compound of the avermectin family, intended for the treatment of internal and external parasites in cattle and in lactating cows.
Eprinomectin is a mixture of two homologues, eprinomectin B1a (90%) and eprinomectin B1b (10%), which differ by a methylene group in the C25.
The recommended dosage regimen is a single dose of 0.5 mg/kg bw (0.1 ml/10 kg bw) applied topically along the midline of the animal's back.  

How does Eprinomectin work?

The precise mode of action of eprinomectin remains unknown, despite extensive investigations with a variety of compounds from the same class.
