Problems solved by technology

However, in the prior art, there are few reports on the proliferation-promoting effect of human basic fibroblast growth factor on the multiple non-fibroblasts that account for the majority in the conjunctiva and cornea, and the effective dose of the pharmaceutical preparation is also unclear, and even more A technical effect of lower doses or even better overall efficacy than higher doses could not be expected
[0004] In addition, the current eye drop preparations for treating eye diseases cannot stay in the eyelids for a long time, so the treatment effect is not good, and the active ingredients are seriously wasted.
Although it can stay in the eyelids for a long time by being formulated into eye ointment preparations, it is limited to use when sleeping because it is a semi-solid object that blocks the line of sight, which brings a lot of inconvenience to patients and limits its popularization and use.

Abstract

The invention belongs to the biological product field, and provides eye drops containing human basic fibroblast growth factors (hbFGF), which is characterized by containing the hbFGFs, sodium hyaluronate, mannitol, albumin, heparin sodium, sodium chloride and the like. In addition, the invention further provides a method for preparing the eye drops and an application of the eye drops in assistingin treating wounds of conjunctiva and cornea.

Description

technical field [0001] The invention belongs to the field of biological products, in particular, the invention relates to eye drops of human basic fibroblast growth factor, its preparation method and its application in auxiliary treatment of conjunctiva and cornea wounds. Background technique [0002] The conjunctival and corneal wounds on the ocular surface often last for more than 1 week without healing, forming persistent conjunctival and corneal defects on the ocular surface. Ocular surface trauma has a variety of causes, such as corneal trauma, surgery involving the cornea, alkaline chemical damage to the cornea or conjunctiva, and toxic reactions from eye drops. If timely and effective treatment cannot be obtained, it can often lead to corneal ulcer or dissolution, or even corneal perforation, which can affect visual function in severe cases. In the traditional wound treatment of the conjunctiva and cornea on the ocular surface, measures such as anti-infection, enhanc...
