Abstract

The invention discloses a broad-spectrum anti-parasitic compound imidacloprid transdermal composition preparation for pets. The transdermal composition preparation contains the following components in parts by weight: 500000-5000000 parts of imidacloprid, 1000-500000 parts of doramectin, 100-20000 parts of pyrethroid, 2000000-8000000 parts of a solvent, 100000-2000000 parts of a penetration enhancer, 1-10 parts of an antioxidant, 500000-5000000 parts of an auxiliary agent. The compound imidacloprid transdermal composition preparation is stable in quality, high in safety, good in transdermal absorption property, good in pesticide effect, good in pesticide effect, low in stimulation, simple and convenient to use and low in environmental pollution, has a relatively long slow release period, can be used for expelling and killing endoparasite and ectoparasite, and simultaneously has functions of preventing mosquitoes and fleas.

Description

technical field [0001] The invention relates to a broad-spectrum anti-parasitic compound imidacloprid transdermal composition preparation for pets and a preparation method thereof. It belongs to the field of veterinary medicine. Background technique [0002] With the improvement of people's living standards, the growing spiritual needs have triggered a pet fever. Pets not only bring a lot of fun to the ordinary life of human beings, but also many people use pets as an emotional support to relieve loneliness and depression, and relieve psychological pressure. However, the contact between pets and the external environment will inevitably infect certain parasites, and people will inevitably have close contact with pets in the common life with pets, which increases the possibility of zoonotic parasitic diseases. Parasites can transmit a variety of diseases, causing harm to the health of pets and humans, and even death in severe cases. [0003] Imidacloprid is a neonicotinoid ...
