The present application relates to a kind of nanoparticles, nano drop eye drops and its preparation method and application, belong to medical technology field.The present application provides a kind of
nanoparticle, the
nanoparticle is composed of
tyrosine kinase inhibitor and
carrier protein;The
mass ratio of
tyrosine kinase inhibitor and
carrier protein is 2~4:1.The present application prepares a kind of
nanoparticle loaded
tyrosine kinase inhibitor, creatively combines it with light-sensitive agent loaded
lipid vesicle, obtains a kind of synergistic photodynamic-VEGF inhibits
bifunctional light-responsive nano drop eye drops, its particle size is uniform, preparation method is simple and easy to operate, and stability is good, realizes the efficient co-delivery of light-sensitive agent,
tyrosine kinase inhibitor, with
laser response release behavior, and can be long time in eye tissue Retention, not only greatly improve the
bioavailability of
hydrophobic drug, and realize the final
curative effect of anti-
ocular angiogenesis, with potential clinical application value.
