Composition of Stronghold drops for dogs
Its active ingredient is selamectin. This substance is active against insects, nematodes and sarcoptoid ticks that parasitize dogs.
Stronghold also kills roundworm larvae. In this case, the drug does not affect the sexually mature nematodes Dirofilaria immitis, but it reduces the number of microfilariae circulating in the blood.
Excipients: dipropelenglycol methyl ether, isopropyl alcohol, butylhydroxytoluene. The composition of solvents and shapers does not include oil, and therefore, after applying the drug, the skin and hair of the animal dry out quickly, which allows the owner to touch the animal and play with it within half an hour after applying the drug.
Pharmacological (biological) properties and effects of Stronghold for dogs
Broad-spectrum antiparasitic drug. Selamectin possesses a wide spectrum of systemic nematodicidal, insecticidal and acaricidal action, is active against nematodes, insects and sarcoptic mites parasitizing dogs and cats. Possesses larvicidal and ovocidal properties.
Pharmacokinetic properties of Stronghold provide good absorption of selamectin from the site of application, long-term preservation in therapeutic concentrations in the organs and tissues of the animal, which ensures the destruction of parasites and protection of animals from reinvasion for a month.
The mechanism of action of the drug lies in the ability of selamectin, to bind to the receptors of cells (muscle and nervous tissue) of parasites, to increase the permeability of membranes for chlorine ions, which leads to blockade of the conduction of nerve and muscle cells of nematodes and arthropods, their paralysis and death.
At recommended doses, Stronghold is safe for dogs and cats due to the fact that in mammals these receptors are localized only in the central nervous system, and selamectin does not penetrate the BBB. Well tolerated by cats and dogs of different breeds (including collies and their crosses).
Stronghold, according to the degree of exposure to the body, belongs to moderately hazardous substances (hazard class 3 according to GOST 12.1.007-76): the LD50 of selamectin for mice when administered into the stomach is 1600 mg / kg, it does not have local irritating, resorptive-toxic and sensitizing effect.

It is not recommended to massage the site of application of the drug.
Stronghold already in the first day relieves the animal of fleas and protects against re-infection within one month. Selamectin (this is Stronghold's active ingredient) destroys mature fleas and eggs, preventing the emergence of a new generation of parasites.

To kill fleas (Ctenocefalides spp.) In dogs, Stronghold is used once, and to prevent re-infestation - once a month throughout the entire season of insect activity. Possessing insecticidal, ovocidal, larvicidal action and interrupting the cycle of insect development, Stronghold, already a month after the first application, provides a sharp decrease in the number of fleas in the animal's habitats.
For the prevention of dirofilariasis in the regions where Dirofilaria immitis is recorded, Stronghold is prescribed to animals on a monthly basis, starting one month before the beginning of summer, the vectors of the pathogen - mosquitoes and mosquitoes and ends no earlier than a month after the end of their summer.
When replacing chemotherapeutic agents in the program for the prevention of dirofilariasis, the interval between the appointment of Stronghold and the previously used drug should be at least 1 month.
Stronghold does not kill sexually mature Dirofilaria immitis, but reduces the number of circulating microfilariae and dirofilaria larvae, and can be applied even to infected animals. In the event that the monthly interval between the use of Stronghold has been exceeded, it is necessary to apply it as soon as such an opportunity arises.
For the treatment of dogs with otodectosis (ear scabies) caused by Otodectos cynotis, Stronghold is used once. It is recommended to clean the ear canal from exudate and scabs, and in cases of complications of otitis media, prescribe antimicrobial and anti-inflammatory drugs. If necessary, the course of treatment is repeated after 1 month.

Before applying the drug, the pipette is removed from the blister, and, holding it vertically, press the cap in order to pierce the foil that covers the pipette, then remove the cap. Stronghold is applied directly to the skin of the animal, spreading the hair between the shoulder blades at the base of the neck, and squeezing out the contents, avoiding it on the hands.
Treatment and prevention of dogs by Stronghold
In experiments conducted under strictly controlled conditions, Stronghold's efficacy against fleas was 99% and 98% for dogs and cats, respectively, for 30 days. For animals that continue to be in conditions of possible re-infestation, monthly use of the drug is recommended.
Destroys fleas not only on animals, but also in the environment. Stronghold provides complete protection for animals, families and homes. At any stage of the development cycle of fleas, only 5% of the population are adult insects that are on the animal; the remaining 95% of the population is located indoors: in floor crevices, under skirting boards, in carpets, etc.
Experimental studies with artificial contamination of the premises show that by the 60th day after the first use of the drug, the contamination of the premises decreases by 97%, and by the 90th day by 98.4%.
These immature stages are a constant source of re-invasion of animals and one of the causes of flea allergic dermatitis. Numerous experiments show that the use of Stronghold alone can significantly reduce the presence of fleas in the home.
Larvae that hatch from eggs that were released into the environment prior to treatment will die shortly after hatching as a result of contact with detritus that falls into the environment from Stronghold-treated animals.
Larvae that begin to feed on flea excrement and detritus from animals treated with Stronghold stop developing and soon die. Only one drop protects people from dangerous zoonotic diseases. From the time of the first application of Stronghold, it may take 30 to 60 days (that is, 1-2 application of Stronghold) for a sharp decrease in the number of eggs and flea larvae in the dwelling.
