4.1 Target species

Dogs.

4.2 Indications for use, specifying the target species

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

Nematodes:

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

Hookworms: Uncinaria stenocephala, Ancylostoma caninum (adults).

Whipworms: Trichuris vulpis (adults).

4.3 Contraindications

Do not use in animals with a known sensitivity to the active ingredients or to any of the excipients.

See section 4.7 below.

4.4 Special warnings for each target species

Dogs kept together or in kennels should be treated at the same time.

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

Fleas serve as intermediate hosts for one common type of tapeworm – Dipylidium caninum. Tapeworm infestation may reoccur unless control of intermediate hosts such as fleas, mice etc is undertaken.

4.5 Special precautions for use

Special precautions for use in animals

The product is not recommended for use in dogs of less than 3 kg bodyweight.

In debilitated or heavily infested animals, the product should be used only according to a benefit/risk assessment by the responsible veterinarian.

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

Wash hands after administration to the animal.

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

People with known hypersensitivity to any of the ingredients should avoid contact with the veterinary medicinal product.

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.

4.6 Adverse reactions (frequency and seriousness)

In very rare cases (less than 1 in 10,000) vomiting can occur.

4.7 Use during pregnancy, lactation or lay

Pregnancy:

Do not use in pregnant bitches during the first 4 weeks of pregnancy.

Lactation:

The product may be used during lactation (see Section 4.9 below).

4.8 Interaction with other medicinal products and other forms of interaction

Do not use simultaneously with piperazine, Levamisole as the anthelmintic effects of pyrantel may be antagonized.

Plasma concentrations of praziquantel may be decreased by concomitant administration with drugs that increase the activity of cytochrome P-450 enzymes (e.g. dexamethasone, phenobarbital).

Concurrent use with other cholinergic compounds can lead to toxicity.

4.9 Amounts to be administered and administration route

Oral use.

The recommended dose rates are: 15 mg/kg bodyweight febantel, 5 mg/kg pyrantel (as embonate) and 5 mg/kg praziquantel. This is equivalent to 1 tablet per 10 kg bodyweight, in a single administration.

Dosages are as follows:

The tablets are flavoured and consequently taken by most dogs voluntarily.

The tablets can be given to the dog with or without food. No starvation is needed before or after treatment.

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

If there is a risk for re-infestation, the advice of a veterinarian should be sought regarding the need for and the frequency of repeat administration.In case of confirmed single infestation by cestode or by nematode, a monovalent product containing a cestocide or a nematocide alone should be used.

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

In safety studies, single doses of 5 times the recommended dose or greater gave rise to occasional vomiting.

4.11 Withdrawal period(s)

Not applicable.

5. PHARMACOLOGICAL PROPERTIES

ATCvet code: QP52AA51.

Pharmacotherapeutic group: anthelmintics.

5.1 Pharmacodynamic properties

In this fixed combination pyrantel and febantel act against all relevant nematodes (ascarids, hookworms, and whipworms) in dogs. In particular the activity spectrum covers Toxocara canis, Toxascaris leonina, Uncinaria stenocephala, Ancylostoma caninumand Trichuris vulpis. This combination shows synergistic activity in the case of hookworms and febantel is effective against T. vulpis.

The spectrum of activity of praziquantel covers all important cestode species in dogs, in particular Taenia spp, Dipylidium caninum, Echinococcus granulosusand Echinococcus multilocularis. Praziquantel acts against all adult and immature forms of these parasites.

Praziquantel is very rapidly absorbed through the parasite’s surface and distributed throughout the parasite. Both in vitro and in vivostudies have shown that praziquantel causes severe damage to the parasite integument, resulting in the contraction and paralysis of the parasites. There is an almost instantaneous tetanic contraction of the parasite musculature and a rapid vacuolisation of the syncytial tegument. This rapid contraction has been explained by changes in divalent cation fluxes, especially calcium.

Pyrantel acts as a cholinergic agonist. Its mode of action is to stimulate nicotinic cholinergic receptors of the parasite, induce spastic paralysis of the nematodes and thereby allow removal from the gastro- intestinal (GI) system by peristalsis.

Within the mammalian system febantel undergoes ring closure forming fenbendazole and oxfendazole. It is these chemical entities which exert the anthelmintic effect by inhibition of tubulin polymerisation. Formation of microtubules is thereby prevented, resulting in disruption of structures vital to the normal functioning of the helminth. Glucose uptake, in particular is affected, leading to a depletion in cell ATP. The parasite dies upon exhaustion of its energy reserves, which occurs 2-3 days later.

5.2 Pharmacokinetic particulars

After oral administration to dogs, praziquantel is extensively and quickly absorbed from the gastro-intestinal tract. Maximum plasma concentration of 752 µg/L is obtained in less than 2 hours. It is rapidly and extensively metabolised in the liver into hydroxylated derivatives of the parent compound, then rapidly eliminated, mainly in urine.

After oral administrationto dogs, febantel is moderately absorbed from the gastro-intestinal tract. Febantel is rapidly metabolised in the liver into fenbendazole and its hydroxy and oxidative derivatives like oxfendazole. Maximum plasma concentration of fenbendazole (173 µg/L) is obtained after about 5 hours. Maximum plasma concentration of oxfendazole (147 µg/L) is obtained after about 7 hours. The excretion occurs mainly in the faeces.

After oral administration to dogs, pyrantel embonate is poorly absorbed. Maximum plasma concentration of 79 µg/L is obtained after about 2 hours. It is rapidly and extensively metabolised in the liver, then rapidly excreted, mainly in the faeces (the unchanged form) and in urine (the metabolites).
