4. CLINICAL PARTICULARS


4.1 Target species


Horse and donkey


4.2 Indications for use, specifying the target species


An oral broad spectrum anthelmintic for the treatment of helminthiasis in the horse and donkey.

The product is effective against benzimidazole - susceptible strains of the following worms:

Large strongyles: Strongylus vulgaris

Strongylus edentatus

Strongylus equinus

Triodontophorus spp.

Small strongyles: Cyathostomes

Stomach worms: Trichostrongylus axei

Ascarids: Parascaris equorum

Pinworms: Oxyuris equi

Probstmayria vivipara

Lungworms: Dictyocaulus arnfieldi



4.3 Contraindications


Do not use in animals with known hypersensitivity to the active ingredient.

Do not treat animals during the first 4 months of pregnancy with doses of 15 mg/kg or over.


4.4 Special warnings for each target species


For use in donkeys at a higher dose rate see Section 4.9.


Horses which are too thin or prone to colic must be examined by a veterinary surgeon prior to treatment.


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 body weight, 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.

Resistance to mebendazole (a benzimidazole) has been reported in cyathostomes in horses within the EU. Therefore the 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.

To reduce this risk dosing programmes should be discussed with your veterinary surgeon.


Special precautions for use


i. Special precautions for use in animals


None


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


Wash hands after use.

Persons with known hypersensitivity to ingredients in the product should not handle the product.

Avoid contact with skin and eyes. Wash off any splashes immediately with clean running water. Seek medical attention if irritation persists.



4.6 Adverse reactions (frequency and seriousness)


None reported


4.7 Use during pregnancy, lactation or lay


Animals should not be treated with a dose of 15 mg/kg or over during the first 4 months of pregnancy.


4.8 Interaction with other medicinal products and other forms of interaction


None known.


4.9 Amounts to be administered and administration route


Route of administration: oral


To ensure administration of a correct dose, bodyweight should be determined as accurately as possible.


Horses:

The dose rate is 5-10 mg mebendazole per kg bodyweight.

1 syringe will treat a horse of 400 – 800 kg

This dose can be repeated every 6 weeks.


Donkeys:

For the treatment of Dictyocaulus arnfieldi give orally at the rate of 15-20mg mebendazole per kg bodyweight daily for 5 consecutive days.

1 syringe will treat a donkey of 200 – 270 kg


This is a single dose product. Part syringe doses must not be used due to the potential for inconsistency in the distribution of the active substance within the syringe.

An alternative product should be used to treat foals, horses weighing less than 400 kg and donkeys weighing less than 200 kg or more than 270 kg.


Administer by squeezing the paste from the syringe onto the back of the tongue.

Previous fasting is not required.


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


Supportive therapy if required.


4.11 Withdrawal period(s)


Animals for human consumption must not be slaughtered until 6 months after treatment.



5. PHARMACOLOGICAL PROPERTIES


Pharmacotherapeutic group: Anthelmintics: Benzimidazoles and related substances; Mebendazole


ATCvet code: QP52AC09


5.1 Pharmacodynamic properties


Mebendazole is an anthelmintic belonging to the benzimidazole group of compounds with efficacy against certain gastrointestinal roundworms and lungworms in horses and donkeys.


Mebendazole acts selectively against the gastrointestinal and lung parasites in the host. It is based on an interaction with the microtubular system of the absorptive cells of the worm, leading to an irreversible lytic necrosis of those cells and death of the worm.


5.2 Pharmacokinetic particulars


The pharmacokinetic profile of mebendazole is similar in various animal species, including horses. Mebendazole has a poor oral bioavailability, due to a low solubility in aqueous systems, a slow dissolution rate in the gastrointestinal tract and first-pass metabolism in the gut wall and the liver. This causes a high faecal excretion of parent drug and low levels in plasma and tissues. Absorption is not linearly dependent of dose. Highest concentrations of mebendazole-related residues are found in the liver and kidneys and these consist mainly of metabolites. The biotransformation of mebendazole involves carbamate hydrolysis, ketone reduction and conjugation. The elimination from plasma and tissues is rapid, although there is some retention of residues in the liver.


The systemic bioavailability of mebendazole in horses is very low, irrespective of the oral dosage form. After a 6.5 mg/kg dose, the concentrations in plasma never exceed 10 ng/ml.
