Further
information
Drontal® Cat
Tablets and Drontal® Cat XL Tablets are an anthelmintic active
against roundworms and tapeworms. The product contains two active
ingredients, pyrantel embonate (pamoate) and praziquantel.
Praziquantel is used widely as an anthelmintic for both human and
veterinary use.
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 vivo and in vitro
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 vacuolisation of the syncytial tegument.
This rapid contraction has been explained by changes in divalent
cation fluxes, especially calcium.
In this fixed
combination product, the pyrantel is active against the following
ascarids: Toxocara cati, and
Toxascaris leonina; the praziquantel is effective against
tapeworms, in particular Dipylidium caninum
and Taenia taeniaeformis.
The product has
been shown to be effective in the control of hookworms
Ancylostoma tubaeforme and A.
braziliense and the tapeworm Joyeuxiella
pasqualei, none of which occur naturally in cats in the UK
but may occasionally be found in imported animals.
Praziquantel is
effective against Echinococcus multilocularis.
E. multilocularis does not occur in the UK
but is becoming more common in some European countries. As a
precautionary measure to prevent establishment of E.
multilocularis in the UK, it is recommended that all cats
entering the country be treated with praziquantel.
Fleas serve as
intermediate hosts for one common type of tapeworm -
Dipylidium caninum. Tapeworm infestation is certain to
re-occur unless control of intermediate hosts such as fleas, mice
etc. is undertaken.
