Pharmacological properties

5.1 Pharmacodynamic properties

Insects and acarines are exposed to deltamethrin through contact. The mechanismof action is based on a sustained increase in the sodium permeability of the insect’s nerve membranes. This results in hyperactivity followed by paralysis (shock effect), tremor and death of the parasite.

5.2 Pharmacokinetic particulars

Deltamethrin is slowly and continuously released from the collar into the dogs’ coat. The active substance spreads from the site of direct contact over the entire skin surface through the lipids and in the hair.

Deltamethrin is not absorbed systemically by the host.

Special warnings

As the collar exerts its full effect after one week, the collar should preferably beapplied 1 week before animals are likely to become exposed to infestation. Ticks and sandflies will be killed and fall off the host within 48 and 24 hours after exposure respectively without having had a blood meal, as a rule. An attachment of single ticks or bite of single sandflies after treatment cannot be excluded. For this reason, a transmission of infectious diseases by ticks or sandflies cannot be completely excluded if conditions are unfavourable.

For optimal control of flea infestations in multi-pet households, all dogs in the household should be treated at the same time.

Fleas from pets often infest the animal’s basket, bedding and regular resting areas, such as carpets and soft furnishings. These should be treated in cases of massive infestation and upon the initiation of control measures with a suitable insecticide, and vacuumed regularly.
