Hydroxypropyl methylcellulose is a partial methyl and partial polyhydroxypropyl ether of cellulose, which can be dissolved in cold water to form a solution with a certain viscosity. Its properties are similar to the viscoelastic substances (mainly mucin) in tears, and it can be used as artificial tears. It adheres to the surface of the eyeball through the adsorption of the polymer, simulates the effect of conjunctival mucin, improves the state of reduced eye mucin, and increases the retention time of the eyeball under the state of reduced tears. This adsorption effect is independent of the viscosity of the solution, ensuring that solutions with very low viscosity can also have a lasting wetting effect. In addition, it can significantly reduce the contact angle of the clean corneal surface, increase the wetting effect of the cornea and improve the stability of the precorneal tear film.

It has atropine-like parasympathetic inhibitory effect, and can cause mydriasis and accommodation paralysis after drug absorption

It has a sympathetic nerve excitatory effect, and after absorption, it manifests as mydriasis and local vasoconstriction
