5.1. Pharmacodynamic properties

Pharmacotherapeutic group: Ophthalmologicals: other ophthalmologicals
ATC code: S0lXA20

Mechanism of action

Vidisic Gel is a substitute for lacrimal fluid. The gel structure has high water-binding capability and forms a stable hydrophilic film that adheres to the ocular surface.

5.2. Pharmacokinetic properties

Absorption

In pharmacokinetic studies, radioactive carbomer was administered to rats. It could be shown that only a small amount of carbomer is absorbed.

As systemic absorption of ocular administration is low, this is not of relevance to the prescriber.

Distribution

Following single administration, 0.75% of the administered dose was detected as carbon dioxide in the expired air, and 0.63% in the urine. The major proportion of carbomer (92%) was detected unchanged in the faeces 24 hours after intake.

5.3. Preclinical safety data

The LD50 value could not be ascertained due to the low toxicity. In studies on rats, no deaths were observed at a concentration of 625 mg/kg carbomer.

Oral doses of 0.5, 1.0 and 3.0 g/kg bodyweight were administered to pregnant rats during a period between days 6 and 13 of gestation. No pathological alterations were seen in the embryos.
