Mechanism of Action

Polyvinyl alcohol, a nonionic surfactant, is used as a stabilising agent, lubricant and as an agent to increase viscosity in pharmaceutical manufacturing. In eye preparations, polyvinyl alcohol is used to increase the viscosity and thereby prolonging contact time of the active ingredient with the eye. It is often found in artificial tears preparations for dry eye and in contact lens solutions.
