Pharmacological properties

  • The drug contains fipronil, diflubenzuron - an insect growth regulator and excipients, including citronella essential oil. It has a pronounced insectoacaricidal activity against the larval and mature phases of the development of fleas, lice, withers, ixodid and sarcoptoid ticks, and also has a repellent effect.
  • After skin application of the drug, its constituent fipronil and diflubenzuron, practically not absorbed into the systemic circulation, accumulate in the epidermis, hair follicles and sebaceous glands of the animal's body and have a long-term contact and intestinal insecticidal effect.
  • The mechanism of action of fipronil is to disrupt the transmission of nerve impulses, which leads to paralysis and death of insects and ticks. Insect growth regulator disrupts the synthesis of chitin in parasites and thus interrupts their life cycle.
