Subcutaneous embedded sustained release preparation for efficiently preventing and treating animal acariasis

Abstract

The invention relates to a subcutaneous embedded sustained release preparation for efficiently preventing and treating animal acariasis. The main content includes steps of mixing drug ivermectin (Doramectin) for killing adult acarid only with drug etoxazole capable of killing acarid ova, larva or nymph or stopping their development through a proper ratio; or respectively preparing to be an animalsubcutaneous embedded sustained release preparation; embedding the preparation in an animal subcutaneous fat tissue, and keeping it to sustainably release in the animal body so that the preparation can kill the acarid in every stage in the living course and stop its development, and overcome the shortcomings of repeatedly occurred acariasis of fur-bearing animal for the ivermectin drug only can skill adult acarid but acarid ova, larva or nymph; besides, the preparation can treat and prevent the animal acariasis after long-effect sustained release, reduce the drug frequency, save labor force and reduce the risk of animal death by poison for a breeder adopts wrong drug and faster formation of acarid with drug resistance; the preparation is economic and practicable, long in drug effect lasting time, and more radical in killing acarid.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of ectoparasites of fur and economic animals, and in particular relates to the development and manufacture of a subcutaneous embedded slow-release preparation for effectively preventing and controlling animal acariasis. Background technique [0002] Fur economic animal acariasis is a contagious ectoparasitic disease caused by mites belonging to Sarcoptesidae and Pruritidae that parasitize in the skin of fur animals. It can lead to hair loss, loss of appetite or no food, weight loss, anemia, and decreased immunity of affected animals, which seriously affects the fur quality, growth and reproduction of fur animals. If the treatment is not timely, it often leads to death, which greatly affects the economic benefits of farmers. Because the only drugs currently on the market for the treatment of fur animal acariasis——the oral preparations or injection preparations of ivermectins (includ...

Problems solved by technology

If the treatment is not timely, it often leads to death, which greatly affects the economic benefits of farmers.

Because the only drugs currently on the market for the treatment of fur animal acariasis——the oral preparations or injection preparations of ivermectins (including doramectin), their acaricidal mechanism is consistent, and they can only Kills adults but not eggs, nymphs, and nymphs, so one administration can only kill part of the adults, and the life cycle of scabies is longer (the life cycle of scabies includes eggs, larvae, nymphs, and adults) stage, it takes 10 to 13 days to develop from eggs to adult mites), and adults can also be re-hatched from unkilled eggs, larvae, and nymphs. In this way, it takes several consecutive medications for a certain period of time to avoid the recurrence of fur animal mite disease attack

Farmers prefer oral administration (convenient), but the dosage and timing of medication are improperly mastered and the use of this type of drug takes a long time, resulting in the current mites have developed obvious resistance to this type of drug, and even the amount of medication has been exceeded. Difficult to eradicate mites even at toxic doses
