Therapeutic indications:

Veterinary drug DECTOMECTIN is indicated for cattle, sheep and pigs for prevention and treatment of parasitic diseases, caused by nematodes of gastrointestinal tract, lungs, subcutaneous tissue, lacrimal ducts; by larvae of subcutaneous and nasopharyngeal gadfly, larvae of flies, lice, scabies mites and ixodid ticks, which are sensitive to doramectin.

Composition of the veterinary drug:

1 ml DECTOMECTIN solution for injection contains:

  • Doramectin 10 mg as an active substance;

Pharmacological activity:

The active substance of the veterinary drug is doramectin with a broad spectrum of antiparasitic activity against nematodes: Oesophagostomum spp., Ostertagia spp. (including encapsulated larvae), Haemonchus spp., Trichostrongylus spp., Cooperia spp., Bunostomum spp., Strongyloides spp., Dictyocaulus spp., Thelazia spp., Nematodirus spp., Trichuris (Trichocephalus) spp., Metastrongylus spp., Parafilaria bovicola, Ascaris suum etc.; larvae of subcutaneous and nasopharyngeal gadfly, such as Hypoderma and Oestrus; biting louse and lice, such as Bovicola, Haematopinus, Linognathus, Solenopotes; scabies mites, such as Psoroptes и Sarcoptes; ixodid ticks (Rhipicephalus microplus) etc.

Doramectin is a macrocyclic lactone. It binds to cell receptors of muscle and nerve tissue of parasites and increases the permeability of membranes for chloride ions, which leads to blockade of the electrical activity in the nerve and muscle cells of nematodes and arthropods, and consequently paralysis and death.

The veterinary drug is easily resorbed from the injection site. Pharmacokinetics of doramectin provides long-term maintenance of therapeutic concentrations of the veterinary drug in blood of animals and protect them from parasitic diseases and reinfection for a long time (up to 28 days).
