Pharmacodynamic Properties

5.1   Pharmacodynamic properties
Pharmacotherapeutic group: Other ophthalmics, artificial tears and other products.
ATC-Code: S01XA20
Hyaluronic acid is a naturally mucopolysaccharide. In humans, it is found mainly in skin, connective tissue, bones and in the vitreous of the eye.
Eyecon contains hyaluronate in the form of its sodium salt.


Mechanism of action
It is biotechnologically produced with the help of a natural strain of Streptococcus.
Sodium hyaluronate shows rheological non-Newtonian behaviour with relatively high viscosity in the state of rest, which reduces flow through the tear canal and prolongs the residence time of Eyecon on the eye.
This rheological property is supported by the carbomer. In contrast, the shear forces during blinking movements decrease the viscosity of Eyecon and allow the eyelids to glidewell on the cornea.
Glycerol is hygroscopic and promotes the retention of water on the cornea and conjunctiva.

Pharmacokinetic Properties

5.2   Pharmacokinetic properties

Eyecon has a purely physical effect on the eye and is not absorbed.
