5 BUTOX PHARMACOLOGICAL or IMMUNOLOGICAL PROPERTIES

Pharmacotherapeutic group: Pyrethrins and pyrethroids.

ATCvet Code: QP53AC11.

5.1 Pharmacodynamic properties

Butox 7.5 mg/ml Pour-on is an ectoparasiticide whose active ingredient Deltamethrin belongs to the synthetic pyrethroids class. Its mode of action concerns the neurotransmission involving sodium channels in the target parasite.

5.2 Pharmacokinetic properties

After dermal application, Deltamethrin is slightly absorbed through skin of cattle and sheep and remains available to the target ectoparasite. The main route of excretion of the absorbed amount in the target animal is the faeces. In terms of residues, fat is the target issue.
