Abstract

The invention relates to a novel eye drop used for pet. The main ingredients of the eye drop comprise a Cecropins antibacterial peptide, a water-soluble chitosan and a borneol. Apart from the broad-spectrum antibacterial activity, the eye drop also has the resistance effect for virus, parasite, fungus and cancer cell which can enhance the immunity and facilitate the wound healing with no resistance to drugs and no residues after long-term usage. Moreover, the water-soluble chitosan is very excellent in viscosity, mould integration property, antibacterial activity and absorbability, which can overcome the deficiencies of conventional eye drops such easy lose and frequent dose.

Description

technical field [0001] The invention belongs to the field of veterinary drugs, in particular to eye drops for pets containing cecropin and a preparation method thereof, eye drops for curing bacterial diseases caused by common pathogenic bacteria in the eyes of pets and a preparation method thereof. Background technique [0002] With the improvement of human living standards, pets have become a member of the family. While pets bring fun to humans, they also seriously threaten human health. The living habits of pets are easy to be exposed to a large number of pathogenic bacteria, and their unique lifestyle can easily bring pathogenic bacteria into the eyes and cause infection. Human beings are in close contact with it, and it is easy to cause contact infection. At present, human eye drops are generally used for pet eye diseases, which are blind and have no obvious effect. In the long run, drug-resistant strains are easy to produce, which seriously threatens human health. Th...
