4. CLINICAL PARTICULARS
4.1 Target species
4.2 Indications for use, specifying the target species
In adult dogs: Treatment of mixed infections by nematodes and cestodes of the following species
Ascarids:Toxocara canis, Toxascaris leonina(adult and late immature forms).
Hookworms:Uncinaria stenocephala, Ancylostoma caninum(adults).
Tapeworms:Echinococcusspecies, (E. granulosus, E. multilocularis), Taeniaspecies,
(T. hydatigena, T. pisiformis, T. taeniformis), Dipylidium caninum(adult and immature forms).
Do not use simultaneously with piperazine compounds.
Do not use in animals with a known sensitivity to the active ingredients 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.
Parasite resistance to any particular class of anthelmintic may develop following frequent, repeated use of an anthelmintic of that class.
4.5 Special precautions for use
Special precautions for use in animals
To ensure administration of a correct dose, body weight should be determined as accurately as possible.
Special precautions to be taken by the person administering the veterinary medicinal product to animals
In case of accidental ingestion, seek medical advice and show the package leaflet to the physician.
In the interests of good hygiene, persons administering the tablets directly to the dog, or by adding them to the dog’s food, should wash their hands afterwards.
4.6 Adverse reactions (frequency and seriousness)
4.7 Use during pregnancy, lactation or lay
Teratogenic effects attributed to high doses of febantel have been reported in sheep and rats. No studies have been performed in dogs during early pregnancy.Useof the product during pregnancy should be in accordance with a benefit risk assessment by the responsible veterinarian. It is recommended that the product is not used in dogs during the first 4 weeks of pregnancy. Do not exceed the stated dose when treating pregnant bitches.
4.8 Interaction with other medicinal products and other forms of interaction
Do not use simultaneously with piperazine compoundsas the anthelmintic effects of pyrantel and piperazine may be antagonized.
Concurrent use with other cholinergic compounds can lead to toxicity.
4.9 Amounts to be administered and administration route
For oral administration only.
The recommended dose rates are: 15mg/kg bodyweight febantel, 5 mg/kg pyrantel (equivalent to 14.4 mg/kg pyrantel embonate) and 5 mg/kg praziquantel. This is equivalent to 1 Cazitel Plus XL tablet per 35 kg bodyweight.
Dogs of > 35 kg bodyweight should be given 1 Cazitel Plus XL tablet plus the appropriate quantity of Cazitel Plus tablets equivalent to 1 tablet per 10 kg bodyweight.
Dogs weighing approx 17.5kg bodyweight should be given ½ Cazitel Plus XL tablet
The tablets can be given directly to the dog or disguised in food. No starvation is needed before or after treatment.
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.
4.10 Overdose (symptoms, emergency procedures, antidotes), if necessary
The combination of praziquantel, pyrantel embonate and febantel is well tolerated in dogs. In safety studies, a single dose of 5 times the recommended doseor greater gave rise to occasional vomiting.
4.11 Withdrawal period
5. PHARMACOLOGICAL PROPERTIES
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 three active substances, as follows:
Febantel, a probenzimidazole
Pyrantel embonate (pamoate), a tetrahydropyrimidine derivative
Praziquantel, a partially hydrogenated pyrazinoisoquinoline derivative
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 Taeniaspp., 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 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 vacuolization 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 gastrointestinal 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
Perorally administered praziquantel is absorbed almost completely from the intestinal tract. After absorption, the drug is distributed to all organs. Praziquantel is metabolized into inactive forms in the liver and secreted in bile. It is excreted within 24 hours to more than 95% of the administered dosage. Only traces of non-metabolised praziquantel are excreted.
Following administration of the product to dogs, peak plasma concentrations of praziquantel were achieved by approximately 2.5 hours.
The pamoate salt of pyrantel has low aqueous solubility, an attribute that reduces absorption from the gut and allows the drug to reach and be effective against parasites in the large intestine. Following absorption, pyrantel pamoate is quickly and almost completely metabolized into inactive metabolites that are excreted rapidly in the urine.
Febantel is absorbed relatively rapidly and metabolized to a number of metabolites including fenbendazole and oxfendazole, which have anthelmintic activity.
Following administration of the product to dogs, peak plasma concentrations of fenbendazole and oxfendazole were achieved by approximately 7-9 hours.
