Pharmacological properties
Combined contact insecticide acting on fleas Ctenocephalides spp. at all stages of development, hair follicles Felicola subrostratus, Trichodectes canis, Ixodes mites Dermacentor variabilis, Rhipicephalus sanguineus, Ixodes scapularis, Ixodes ricinus, Ixodes holocyclus, Haemaphysalis longicornis, Haemaphysalis aeval, Haemaphysalis camva, Haemaphysalis camva Sarcoptes scabiei var. canis, other insects that parasitize dogs, cats and ferrets.
Fipronil belongs to the insecticides of the phenylpyrazole group. Selectively blocks the work of GABA-dependent chlorine ion channels in the membranes of arthropod nerve cells, which leads to disruption of nerve impulse transmission, convulsions and death of ectoparasites.
S-methoprene is an analogue of juvenile hormone, which acts as a regulator of insect growth and inhibits their growth and morphological development at the stages of eggs, larvae and pupae, due to antagonism with ecdysone, which is responsible for the growth and development of the larva. The ovocidal effect of S-methoprene is manifested as a result of direct penetration into the shell of the laid eggs.
After topical application to the skin, fipronil is slowly absorbed (up to 11%) with a low maximum plasma concentration (Cmax) of about 35 ng / ml fipronil and 55 ng / ml of its major extensive metabolite fipronil sulfone. The maximum concentration of fipronil in blood plasma is reached slowly (after about 100 hours) and slowly decreases (elimination period – more than 150 hours).
Plasma concentrations of S-methoprene after dermal application are below the limits of their quantification (20 ng / ml).
S-methoprene and fipronil together with its metabolite fipronil-sulfone are well distributed in the fur of animals during the day after application. Their concentrations in the coat decrease over time, but the drug itself is detected even 60 days after application.
Ectoparasites die mainly due to contact with the drug: fleas – within 24 hours, mites and lice – within 48 hours. The drug is effective against fleas at all stages of their development for 8 weeks, against ticks – for at least 4 weeks after application.
Fipren is a low-toxic substance for warm-blooded animals and in the recommended doses does not give skin irritation, resorptive-toxic, embryotoxic and teratogenic effects.
Method of application and dosage
The drug is applied with pipettes directly to the dry, healthy skin of animals so that the animal could not lick it – on the back between the shoulder blades.
