Pharmacological particulars
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.
