Abstract

The invention discloses recombinant bovine alkaline fibroblast growth factor eye drops and a preparation method thereof. The recombinant bovine alkaline fibroblast growth factor eye drops are prepared from the following components by weight: 1500-2500 IU of recombinant bovine alkaline fibroblast growth factor, 0.04-0.12mg of human albumin, 2.0-6.0mg of polyvinyl alcohol, 4.0-6.0mg of sodium chloride, 0.20-0.30mg of disodium hydrogen phosphate, 0.40-0.50mg of sodium dihydrogen phosphate and 0.4ml of water for injection. According to the recombinant bovine alkaline fibroblast growth factor eye drops disclosed by the invention, the dosage of auxiliary material is reduced in the eye drops, the stability of the eye drops is also ensured, the shelf life of the eye drops is prolonged, and the application range is enlarged; without the addition of a bacteriostatic agent, the potential risk caused by the bacteriostatic agent and the toxic or side effect to eyes are prevented, and the irritation of the eye drops to eyes is reduced, and the eye drops are safe in use and high in compliance of a patient.

Description

technical field [0001] The present invention relates to the field of biological products. In particular, it relates to a recombinant bovine basic fibroblast growth factor eye drop and a preparation method thereof. Background technique [0002] Basic fibroblast growth factor (bFGF), belonging to the FGF family (23 known members), is a heparin-binding growth factor that promotes cell growth in a range of cells including mesenchymal, neuroectoderm, and vascular endothelial cells. proliferation. Basic fibroblast growth factor also has potential pro-angiogenic activity in vivo. bFGF is mainly distributed in tissues and organs derived from mesoderm and neuroderm. It has effects on many tissue cells, can promote cell division, regulate cell metabolism, affect cell morphology, infiltration, differentiation and aging, and affect corneal epithelial cells, stromal cells, and endothelial cells. Both can have an effect on the regeneration of alkali-burned corneal epithelium, and the r...
