Abstract

The invention discloses a milbemycin oxime nano suspension for treating dog parasitic diseases and a preparation method thereof. Each 100 mL of suspension contains 2 to 5 grams of milbemycin oxime, 0.1 to 0.4 mL of wetting agent, 3.0 to 5.5 grams of suspending agent, 1.0 to 2.0 grams of flocculating agent, and the balance being purified water or injection water. The provided milbemycin oxime nano suspension is mainly made of milbemycin oxime, and at the same time, a wetting agent, a suspending agent, and a flocculating agent are added, so the milbemycin oxime nano suspension has a stable property and can be used to prepare oral or injection drugs. The detention time of the drugs in human body is prolonged, thus the drugs can be fully absorbed by human body, and the biological utilization degree is improved. The milbemycin oxime nano suspension is used to treat dog in-vitro / in-vivo parasitic diseases in clinic and has the advantages of safety, good curative effect, little side effect, and user-friendliness.

Description

technical field [0001] The invention belongs to the technical field of veterinary medicine, and in particular relates to a milbexime nanosuspension for treating canine parasitic diseases, and also relates to a preparation method of the milbexime nanosuspension for treating canine parasitic diseases . Background technique [0002] Parasitic disease is a kind of disease that pets are relatively easy to get. Usually, parasites cause mechanical damage to pets by consuming nutrients in pets, causing pets to suffer from slow growth, stagnation, emaciation, anemia, and emaciation due to lack of nutrition; or miscarriage, stillbirth, loss of fertility; or rough skin , dermatitis, itching, hair loss, frailty, decreased immunity, disease resistance, prone to diseases, infectious diseases, etc. After pets suffer from parasitic diseases, due to frequent contact with humans, most of the parasites can be transmitted to humans through pets, resulting in stunted children, mental retardati...
