Composition based on gellan gum and phenylephrine, production method and use as an ophthalmic product

A composition in the form of a solution having a viscosity of less than or equal to 500 mPa·s at a temperature between 20° and 25° C., consisting of:

• gellan gum,
• phenylephrine or phenylephrine in combination with tropicamide,
• sodium citrate in an amount ranging from 0.01 to 0.2% w/v as a gelation regulating agent,
• a cellulose derivative in an amount 0 to 2% w/v;
• a chelating agent in an amount 0 to 0.2% w/v;
• and
• water;
• and
• wherein after the composition is applied to the eye, the composition has a gel viscosity at rest when the eye is open and a lower viscosity under the eyelid shear, thereby decreasing eye irritation and discomfort.
