Hydroxypropyl methylcellulose eye drops
Function and Efficacy
Hydroxypropyl methylcellulose is a partial methyl and partial polyhydroxypropyl ether of cellulose. It can be dissolved in cold water to form a solution with a certain viscosity. Its properties are close to the viscoelastic substances (mainly mucin) in tears. Therefore, it can be used as artificial tears. Its mechanism of action is: it attaches to the surface of the eyeball through the adsorption of the polymer, simulating the effect of conjunctival mucin, thereby improving the state of reduced eye mucin and increasing the retention time of the eyeball under the state of reduced tears. This adsorption effect is independent of the viscosity of the solution, thus ensuring that solutions with very low viscosity can also have a very long-lasting wetting effect. In addition, it can also increase the stability of the precorneal tear film by significantly reducing the contact angle of the clean corneal surface and increasing the wetting of the cornea.
Ingredients
Each 1 mL of this product contains 3 mg of hypromellose, and also contains auxiliary materials such as 0.1 mg of benzalkonium chloride and 1.0 mg of disodium edetate.

It can be dissolved in cold water to form a solution with a certain viscosity. Its properties are similar to those of viscoelastic substances in tears and can be used as artificial tears. It adheres to the surface of the eyeball through the adsorption of polymers, simulates the effect of conjunctival mucin, improves the state of reduced eye mucin, and increases the retention time of the eyeball in the state of reduced tears. It can also increase the stability of the tear film before the cornea. More |
