  • Pharmacological properties

    Doramectin refers to the last generation of macrocyclic lactones and is a metabolic byproduct of microorganisms from the Streptomycetaceae family. 

    Doramectin is obtained by way of mutational biosynthesis, where the mutated streptomyces avermitilis strain was used to produce avermectins.

    The drug has a broad spectrum of insecticidal, nematicidal and acaricidal action; it is active against nematodes of the gastrointestinal tract, lungs, subcutaneous tissue, gadfly larvae, as well as Sarcoptoidea and red ticks. Doramectin contained in the drug binds with muscle cell and nervous tissue receptors, increases membrane permeability for chlorine ions, causing blockage of nerve impulses that leads to paralysis and death of the parasite. Doramectin is quickly absorbed from the administration site; it enters the systemic circulation, tissues and organs, reaching the peak concentrations within 4-5 days, remains in the body for a long period providing protection against re-infestation for 28 days.

  • Dosage and route of administration
  • Dosage and route of administration

    Meradok shall be administered once parenterally, under aseptic conditions using dry sterile syringes and needles, at the following doses:

    - In cattle: subcutaneous administration in the neck area, 1 mL per 50 kg of body weight (equivalent to 0.2 mg of doramectin per 1 kg);

    - In sheep: intramuscular administration in the neck area or femoral muscle, 1 mL per 50 kg of animal body weight (equivalent to 0.2 mg of doramectin per 1 kg of weight);

  • Restrictions
  • Restrictions

    Due to the release of doramectin in milk, the drug use to dairy, as well as pregnant cows less than 60 prior to the expected date of delivery; to sheep, less than 70 days prior to the expected delivery date is prohibited.
