What is Stronghold used for cats?

Stronghold is used according to the instructions for the treatment and prevention of flea infestation (Ctenocephalides spp.) in cats.
This remedy is very helpful as part of a flea allergy dermatitis treatment regimen. In addition, Stronghold drops can be used to treat cats with ear mites (Otodectes cynotis) and to prevent heartworm infestation (Dirofilaria immitis).

In cats, Stronghold drops on the withers can also be used to treat adult intestinal roundworms (Toxocara cati), as well as adult intestinal nematodes (Ancylostoma tunbaeforme) and lice infestations (Felicola subrostratus).

pharmachologic effect

Stronghold acts against a large number of skin and intestinal parasites. Selamectin has proven clinical effectiveness against nematodes, insecticide and acaricide. In addition, it is highly effective in destroying skin parasites: sarcoptic mites, fleas and other blood-sucking insects. Kills not only the adult forms of parasites, but also eliminates the larval stages and eggs of insects.

Pharmacokinetic properties

Stronghold is characterized by rapid absorption of the active component at the site of application. It cannot be used orally, as it is destroyed by gastric juice. When used externally, it is quickly absorbed. It accumulates for a long time in the organs and tissues of the pet, providing not only a therapeutic, but also a preventive effect.

Insects and helminths, when parasitizing and eating tissues and blood cells, also consume selamectin, which leads to the death of the parasites. The drug is retained in tissues for a month in a sufficiently high concentration, which prevents re-invasion by the parasite. That is why the larvae hatched from the eggs also die under the influence of the medicine.

Mechanism of action

Selamectin freely passes through the membranes of parasite cells, reaching muscle and nervous tissue. There it binds to receptors and increases the permeability of cell membranes to chlorine ions. This reduces the sensitivity of cells to nerve impulses to zero, resulting in complete paralysis. Penetrating into the central nervous system of the parasite, selamectin blocks brain activity, which again leads to death.

Moreover, the drug does not damage the nervous system of mammals, since in canines and cats these receptors are located only in the central nervous system, which is separated from the bloodstream by an impenetrable blood-brain barrier. The BBB is present in all vertebrates and protects the brain from the immune system, toxins and parasites.

In terms of the level of effect on the internal organs and tissues of the animal, Stronghold is classified as a third hazard class (according to GOST 12.1.007-76), that is, a moderately harmful drug. The 50% lethal dose for rodents when administered orally is 1.6 mg/g. In recommended quantities, it does not cause superficial skin irritation and does not have a toxic effect when absorbed into the blood. Negative side effects do not occur even with a tenfold increase in the therapeutic dose.

Additional information about the veterinary drug Stronghold for domestic cats

According to the instructions, Stronghold is a colorless or yellow liquid medication that is applied topically to the skin of the back of the neck of cats once a month. This product contains the active ingredient selamectin, which is an insecticide. Stronghold comes in single-use plastic pipettes and is manufactured by Pfizer Ltd. The pipettes are supplied in a foil blister pack and each box contains 3 pipettes. Cat Strength is also available in boxes of 6 droppers. The pipettes come in different sizes so that the drug can be dosed appropriately to cats of different weights.

Stronghold kills adult fleas and stops the production of viable eggs. It also kills the larval stages of fleas, thus stopping reproduction and disrupting the life cycle of fleas. It is recommended to use Stronghold monthly for both treatment and prevention of fleas, especially throughout the season, starting treatment a month before fleas become active. Drops on the withers are also used to treat and/or prevent a number of other parasites such as mites, roundworms and lice. The dosage of Stronghold required to treat these parasites is as follows:

• Roundworms (nematodes): treated with one dose of Stronghold
• Hookworm: Treatable with a single dose
• Lice: Treatment with One Dose of Stronghold
• Sarcoptic mange: treatment with a single dose of Stronghold for 2 consecutive months
• Ear mites: If the drops are given once, cats may need an additional dose after 30 days.
• Heartworm: Year-round monthly treatment with Stronghold, at least starting one month before and ending one month after mosquito exposure

Although one dose of Stronghold is sufficient to treat most of these parasites, it is recommended that Stronghold be used year-round for both prevention and treatment.

According to the instructions for use, Stronghold drops can be used in animals older than 6 weeks, including pregnant and lactating animals.

Collies do not respond well to other drugs in the same class as selamectin, but Stronghold has been shown to be safe for this dog breed even at 5 times the recommended dose. Sometimes mild and temporary hair loss may occur at the site of application of the drops. If the animal licks the drug, increased salivation may occur. Transient neurological signs may occur. You should not apply Stronghold to a wet animal, and you should avoid getting your pet wet for 2 hours after application. This product is flammable, so you should keep your pet away from fire for 30 minutes after application or until the hair is dry. Strength may leave a white powder on the coat after application, but this should happen within 24 hours.

Indications for use

The instructions say that the use of Stronghold is advisable in the following cases:

• diseases caused by fleas and lice;
• ear scabies;
• sarcoptic mange (subcutaneous mite);
• hookworm (infection with helminths of the genus nematodes);
• toxocariasis (infestation by Toxocara - nematodes).

Drops can be used to destroy ecto- (external) and endoparasites (internal) and prevent infection by them.

Stronghold is used to prevent dirofilariasis (infestation by heartworms of the nematode genus) in cats.

Important! There is no safe treatment regimen for dirofilariasis yet, so the only method to avoid the disease and protect your pet is prevention. Stronghold has a detrimental effect on microfilariae (heartworm larvae) and does not allow them to develop into adults.

Operating principle

Stronghold has a wide spectrum of action. Selamectin has a detrimental effect on internal and external parasites: fleas, lice, ticks and roundworms (nematodes). It destroys adult individuals (except heartworms), larvae, and eggs.

The active substance binds to the receptors of nerve and muscle cells of ecto-/endoparasites. Under its influence, the permeability of membranes increases, which begin to let chlorine ions into the cell. Because of this, neuromuscular transmission is disrupted. The insect, tick or helminth is paralyzed and subsequently dies.

Drops against worms, ticks and fleas penetrate well into the bloodstream after application. Selamectin in a therapeutic dosage remains in tissues and organs for a long time. Therefore, the solution destroys parasites and protects the cat from re-infection for 4 weeks.

Interesting! The likelihood of cats or dogs being poisoned by Stronghold is low. This is due to the fact that in animals, receptors sensitive to selamectin are located in the central nervous system, and the main substance does not penetrate the BBB (barrier between the bloodstream and the central nervous system).

The instructions say that Stronghold is a low-toxic drug (hazard class 3). If the dosage is observed, it does not cause negative reactions. However, it is dangerous for bees, fish and other water inhabitants.
