3. CLINICAL INFORMATION

3.1 Target species

Dogs.

3.2 Indications for use for each target species

Treatment of mixed infections by nematodes and cestodes of the following species:

Roundworms:

Ascarids (adult and late immature forms): Toxocara canis, Toxascaris leonina

Hookworms (adults): Uncinaria stenocephala,

Ancylostoma caninum

Whipworms (adults): Trichuris vulpis

Tapeworms (adult and immature forms): Echinococcus granulosus

3.3 Contraindications

Do not use in cases of hypersensitivity to the active substances or to any of the excipients.

Do not use during the 1st and 2nd third of pregnancy (see section 3.7).

3.4 Special warnings

Fleas serve as intermediate hosts for one common type of tapeworm - Dipylidium caninum. Tapeworm infestation is certain to re-occur unless control of intermediate hosts such as fleas, mice etc. is undertaken.

3.5 Special precautions for use

Special precautions for use in the target species:

Parasite resistance to any particular class of anthelmintic may develop following frequent, repeated use of an anthelmintic of that class.

To minimise the risk of reinfestation and new infestation, excreta should be collected and properly disposed of for 24 hours following treatment.

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

In case of accidental ingestion, seek medical advice immediately and show the package leaflet or the label to the physician.

In the interests of good hygiene, persons administering the product directly to a dog or by adding it to the dog’s food should wash their hands afterwards.

Special precautions for the protection of the environment:

Not applicable.

Other precautions:

Since it contains praziquantel, the product is effective against Echinococcus spp. which do not occur in all EU member states but are becoming more common in some. Echinococcosis represents a hazard for humans.

As Echinococcosis is a notifiable disease to the World Organisation for Animal Health (OIE), specific guidelines on the treatment and follow-up, and on the safeguard of persons, need to be obtained from the relevant competent authority.

3.6 Adverse events Dogs:

Very rare (<1 animal / 10,000 animals treated, including isolated reports):

Digestive tract disorders (e.g., vomiting and diarrhoea)1 Anorexia, Lethargy, Hyperactivity.

¹Mild and transient.

Reporting adverse events is important. It allows continuous safety monitoring of a veterinary medicinal product. Reports should be sent, preferably via a veterinarian, to either the marketing authorisation holder <or its local representative> or the national competent authority via the national reporting system. See the package leaflet for respective contact details.

3.7 Use during pregnancy, lactation or lay

Pregnancy and lactation:

Teratogenic effects attributed to high doses of febantel administered during early pregnancy have been reported in rats, sheep and dogs.

The safety of the product has not been investigated during the 1st and 2nd third of pregnancy. Do not use in pregnant dogs during the 1st and 2nd third of pregnancy (see section 3.3).

A single treatment during the last third of pregnancy or during lactation has been demonstrated safe.

3.8 Interaction with other medicinal products and other forms of interaction

The anthelmintic effects of this product and piperazine containing products may be antagonized when the two drugs are used together.

Concurrent use with other cholinergic compounds can lead to toxicity.

3.9 Administration routes and dosage

For oral administration only.

Dosage

For treatment of dogs, 1 tablet per 10 kg body weight (15 mg febantel, 14.4 mg pyrantel embonate and 5 mg praziquantel/kg body weight). Dosages are as follows:

Tablets should be given as a single administration.

The advice of a veterinarian should be sought regarding the need for and frequency of repeat treatment.

Not for use in dogs weighing less than 2 kg.

To ensure a correct dosage, body weight should be determined as accurately as possible.

4. PHARMACOLOGICAL INFORMATION

4.1 ATCvet code:

QP52AA51

4.2 Pharmacodynamics

The product is an anthelmintic containing as active substances the tetrahydropyrimidine derivative pyrantel (as the embonate salt), the probenzimidazole febantel and praziquantel, a partly hydrogenated pyrazinoisoquinoline derivative. It is effective against certain roundworms and tapeworms.

In this fixed combination pyrantel and febantel act synergistically against roundworms (ascarides, hookworms and whipworms) in dogs. In particular, the action spectrum covers Toxocara canis, Toxascaris leonina, Uncinaria stenocephala, Ancylostoma caninum, and Trichuris vulpis.

The spectrum of activity of praziquantel covers tapeworm species in dogs. In particular, it includes all Taenia species, as well as Multiceps multiceps, Dipylidium caninum, Echinococcus granulosus andEchinococcus multilocularis. Praziquantel acts against all intestinal stage of these parasites.

Pyrantel acts as the nicotine, as a cholinergic agonist, causing spastic paralysis of roundworms via a depolarising neuromuscular block.

The anthelmintic efficacy of febantel is due to its ability to inhibit the polymerisation of tubuline to microtubuli. The resulting structural and functional metabolic disturbances exhaust the parasite’s energy reserves and kill it in 2-3 days.

Praziquantel is absorbed very rapidly through the parasite’s surfaces and is evenly distributed throughout their bodies. It causes severe damage of their integument, leading to disruption of metabolism and thence to death.

4.3 Pharmacokinetics

Praziquantel is absorbed almost completely in the small intestine following oral administration to dogs. Absorption is very rapid reaching maximum serum levels within 0.5 to 2 hours. After absorption, the drug is widely distributed through the body. Plasma protein binding is high. Praziquantel is rapidly metabolized in the liver leading to inactive metabolites. In dogs, metabolites are eliminated by urine (66 % of an oral dose) and via the bile (15%) in the faeces. Elimination half-life in dogs is about 3 hours.

Pyrantel (as embonate), being a low water-soluble compound, is poorly absorbed in the gastrointestinal tract, reaching the final parts of the intestine. The absorbed drug is extensively metabolized and the parent compound/metabolites are excreted by urine.

Febantel is a pro-drug that after oral administration and oral absorption is metabolized to fenbendazole and oxfendazole, the chemical entities exerting the anthelmintic effect. The active metabolites are excreted via faeces.
