Lufenuron is an insect growth regulator belonging to the benzolyurea group which acts by interfering with the normal synthesis, polymerisation and deposition of chitin.
Pharmacodynamic properties
ATC vet code: QP53BC01
Fleas take up the active ingredient through the blood and transfer it to their eggs. The formulation of larval chitin structures, a process typical to insects is blocked and the development of their numerous offspring is stopped. A new infestation of the home with fleas is prevented.
Fleas picked up by the cat outside the home environment are prevented from causing a new infestation of the home.
Pharmacokinetic particulars
After administering orally to the cat, the active ingredient is quickly absorbed. Sufficient absorption is only achieved if administered on a full stomach. The low excretion rate ensures an effective concentration of the active ingredient in the blood for one month.
