Pharmacological properties

4.1 ATCvet code: QP 52 AA 01

4.2 Pharmacodynamics

The spectrum of action of praziquantel covers all the important species of cestodes in dogs and cats. It specifically includes all Taenia species occurring in dogs and cats, Multiceps multiceps, Joyeuxiella pasquali, Dipylidium caninum, Mesocestoides species, Echinococcus multilocularis and E. granulosus. Praziquantel is effective against all stages of development of these parasites occurring in the intestines of dogs and cats.

Praziquantel impairs the normal tegument function of the parasite, making it permeable to excessive glucose loss and thereby more easily attacked by proteolytic enzymes. Because of this, whole tapeworms including the scolex are very rarely passed in the faeces following administration of the drug. Disintegrated and partially digested fragments may occasionally be seen in the faeces.

4.3 Pharmacokinetics

Praziquantel is rapidly absorbed by the animal and metabolised by the liver. It is excreted, entirely as metabolites, in the urine and faeces.

Droncit is also effective against Echinococcus multilocularis (see 3.4)

Dosage

Dosage

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

The recommended dosage rate is 5 mg/kg body weight. This corresponds to 1 tablet per 10 kg body weight.

Dogs 2.5 to 5 kg ½ tablet

Greater than 5 to 10 kg 1 tablet

Greater than 10 to 15kg 1 ½ tablets

Greater than 15 to 20 kg 2 tablets

Greater than 20 to 25 kg 2 ½ tablets

Greater than 25 to 30 kg 3 tablets

Over 30kg pro rata For each additional 5kg bodyweight, administer an additional half tablet

Cats Adult cats ½ tablet

Administration and Duration of Treatment

Oral administration. The tablets are administered by opening the animal’s mouth and pushing the tablet over the back of the tongue so that it cannot be rejected. Alternatively, a tablet can be wrapped in a piece of meat or butter and offered to the animal or crushed and mixed with the food.

A single dose is all that is required. However, for dogs in rural areas and for packs of hounds, this dose should be repeated every four weeks to ensure that newly acquired tapeworms are destroyed before reaching maturity. Dosing must be associated with strict control of the dog’s diet to ensure that uncooked offal is not eaten.

3

Contraindications

Do not use in dogs weighing less than 2.5 kg

Do not use in unweaned puppies and kittens, as such animals are rarely infected with tapeworms.

Special warnings

Fleas serve as intermediate hosts for one common type of tapeworm - Dipylidium caninum. To avoid reinfection with this parasite, flea control of the animal and its housing should be carried out at the same time. Unless flea control is complete an infected flea population may survive: i.e. re-treatment of the animal may be necessary.

As a precautionary measure to prevent the establishment of Echinococcus multilocularis in the UK and Ireland, it is recommended that all dogs and cats entering the country be treated with praziquantel.
