COMMENTS

DRONCIT SPOT-ON is an original spot-on from BAYER against tapeworms for cats with praziquantel. Praziquantel is mostly used in the form of tablets or suspensions for oral administration; this is one of the very few products where it is used as a topical spot-on.

Praziquantel is a veteran isoquinoline anthelmintic introduced in the 1970s (by BAYER). It is effective against most tapeworms that infect cats (e.g. Dipylidium caninum, Taenia sppEchinococcus multilocularis) but has no efficacy whatsoever against roundworms or hookworms. There are hundreds of antiparasitic brands for pets containing praziquantel, but rather few as a spot-on.

Praziquantel has no residual effect, i.e. it acts against the worms during a few hours after administration but is quickly metabolized and excreted. For this reason treatment must often be repeated for certain indications. 

BAYER markets praziquantel also as tablets (DRONCIT) and as an injectable (DRONCIT INJECTABLE), as well as tablets with pyrantel + praziquantel for cats against roundworms and tapeworms (DRONTAL), and tablets with febantel + praziquantel + febantel for dogs against roundworms, hookworms and tapeworms (DRONTAL PLUS).
