4.1 Target Species


4.2 Indications for use, specifying the target species

For the treatment of mixed infections caused by the following gastrointestinal roundworms and tapeworms:

Roundworms: Toxocara cati, Toxascaris leonina,

Tapeworms: Dipylidium caninum, Taeniataeniaeformis, Echinococcus multilocularis.

4.3 Contraindications

Do not use simultaneously with piperazine compounds.

Do not use in kittens less than 6 weeks of age.

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

4.4 Special warnings for each target species

Fleas serve as intermediate hosts for one common type of tapeworm – Dipylidium caninum. Tapeworm infestation is certain to

reoccur unless control of intermediate hosts such as fleas, mice, etc. is undertaken.

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 cats. Local epidemiological information and the living conditions of the cat should be taken into

account. It is also important to remove sources of possible re-infection such as fleas and mice.

4.5 Special precautions for use

Special precautions for use in animals

Parasitic resistance to a certain class of anthelmintics can occur after frequent and repeated use of an anthelmintic from this


As the tablets are flavoured, they should be stored in a safe place out of the reach of animals. Animals in a poor condition or

heavily infested, which can be manifested by symptoms such as diarrhoea, vomiting, presence of parasites in faeces and vomit,

poor hair condition, should be examined by a veterinarian prior to the product administration. For severely debilitated or

heavily infested cats, use only according to a benefit/risk assessment by the responsible veterinarian

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

In the interests of good hygiene, persons administering the tablets directly to the cat, or by adding them to the cat's food,

should wash their hands afterwards.

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

Other precautions

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, gastrointestinal disorders (vomiting) & neurological signs such as ataxia and muscle tremors have been


The frequency of adverse reactions is defined using the following convention:

- very rare (less than 1 animal in 10,000 animals treated, including isolated reports)

4.7 Use during pregnancy, lactation or lay

Do not use during pregnancy but may be used during lactation.

4.8 Interaction with other medicinal products and other forms of interactions

Do not use simultaneously with piperazine compounds.

4.9 Amounts to be administered and administration route

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


The recommended dose is: 20 mg/kg pyrantel (57.5mg/kg pyrantel embonate)and 5 mg/kg praziquantel.This is equivalent to 1

tablet per 4 kg bodyweight.

Body weight


1.0 - 2.0 kg

2.1 - 4.0 kg

4.1 - 6.0 kg

1 ½

6.1 - 8.0 kg

Administration and duration of treatment

Single oral administration.The tablet should be given directly to the cat, but if necessary can be disguised in food.

In ascarid infestation, especially in kittens, complete elimination cannot be expected, so a risk of infection for humans can

persist. Repeat treatments should, therefore, be carried out with a suitable roundworm product at 14 day intervals until 2-3

weeks after weaning.

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

After doses higher than 5 times the recommended dose, signs of intolerance such as vomiting have been observed.

Pharmacotherapeutic group: Anthelmintic, praziquantel combinations.

ATC vet code: QP52AA51

5.1 Pharmacodynamic properties

This product contains anthelmintics active against gastrointestinal roundworms and tapeworms.The product contains two

active substances, as follows:

1.Pyrantel embonate (pamoate), a tetrahydropyrimidine derivative

2.Praziquantel, a partially hydrogenated pyrazinoisoquinoline derivative.

Pyrantel acts as a cholinergic agonist.Its mode of action is to stimulate nicotinic cholinergic receptors of the parasite, induce

spastic paralysis and thereby allow expulsion from the gastro-intestinal (GI) system by peristalsis.

Praziquantel is very rapidly absorbed and distributed throughout the parasite.Both in vitro and in vivo studies have shown that

praziquantel causes severe damage to the parasite integument, resulting in contraction and paralysis.There is an almost

instantaneous tetanic contraction of the parasite musculature and a rapid vacuolization of the syncytial tegument.This rapid

contraction has been explained by changes in divalent cation fluxes, especially calcium.

In this fixed combination, pyrantel is active against the following ascarids: Toxocara cati, and Toxascaris leonina. Praziquantel is

effective against tapeworms in particular Dipylidium caninumand Taenia taeniaeformis.

Since it contains praziquantel, the product is effective against Echinococcus multilocularis.

5.2 Pharmacokinetic particulars

Praziquantel is rapidly absorbed, metabolised and distributed in the body. It is also believed to be excreted back into the

intestinal lumen by the mucous membrane. Following administration of the product to cats, peak plasma concentrations of

praziquantel were achieved by approximately 2 hours.

Pyrantel is poorly absorbed so it is expected that a large proportion of the administered dose remains in the GIT where it exerts

its therapeutic effect and it is excreted largely unchanged in the faeces.

Following administration of the product to cats, peak plasma concentrations of pyrantel were achieved by approximately 3
