Method of Administration


Remove one tube from the package. Hold tube in an upright position, twist and pull off cap. Use reversed cap to twist and remove seal from tube.



Part the hair on the cat's neck at the base of the skull until the skin is visible.



Place the tip of the tube on the skin and squeeze firmly several times to empty the contents directly onto the skin. Application at the base of the skull will minimise the opportunity for the cat to lick the product.


To minimise the possibility of run-off after application of more than one pipette, it is advised that the applications should be performed slowly to allow absorption and that it may be advisable to allow the contents of the previous pipette to be absorbed before applying another.


Tapeworm infestation is certain to re-occur unless control of intermediate hosts such as fleas, mice etc. is undertaken.


Flea control: flea infestations can be controlled by the regular use of effective flea control remedies.


Mice control: if cats roam and hunt, contact with, and consumption of, mice and subsequent re-infestation with Taenia taeniaeformisis impossible to prevent.


It is recommended to re-apply the product when signs of tapeworm infestation re-appear or at monthly intervals.



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


Overdosing can lead to slight skin reactions which disappear without treatment within a few days.


4.11 Withdrawal period(s)


Not applicable as the product is not indicated for the treatment of food producing animals.


5. PHARMACOLOGICAL PROPERTIES


The Active Ingredient


Praziquantel, the active ingredient of the product is a pyrazinoisoquinoline derivative used widely as an anthelmintic for both human and veterinary medicine. The chemical name for this substance is 2-cyclohexyl-carbonyl[1,2,3,6,7,11b] hexahydro-4H-pyrazino-[2,1-a]isoquinolin-4-one1.


ATCVet Code: QP52AA01


5.1 Pharmacodynamics


Praziquantel is effective against all stages of development of intestinal tapeworms. The substance is very rapidly absorbed and distributed throughout the parasite. Both in vivo and in vitrostudies 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 vacuolisation of the syncytial tegument. This rapid contraction has been explained by changes in divalent cation fluxes, particularly calcium.


5.2 Pharmacokinetics


Praziquantel is absorbed very rapidly and almost completely in the stomach and small intestine. Studies of the behaviour following oral administration have been conduced in rats, dogs, monkeys, sheep and humans. Depending on species, maximum serum levels are reached within 0.3 to 2 hours. The chemical is evenly distributed to all organs. The elimination half-lives of 14C-praziquantel and its metabolites are between 2 and 3 hours in rats, dogs, monkeys and sheep.


Praziquantel is rapidly metabolised in the liver in both humans and animals with the 4-hydroxycyclohexyl derivative as the main metabolite. Praziquantel is completely eliminated from the body within 48 hours; irreversible binding to body constituents has not been observed. Elimination is in the form of metabolites with virtually no parent compound excreted. Between 40% and 71% of the substance is eliminated in the urine and 13%-30% in the faeces.
