Cornea preparation for in vitro bio-pharmaceutical evaluation of ophthalmic dosage forms.
A system has been developed for a specific biopharmaceutical purpose: testing for ophthalmic preparations, the influence of formulation on drug transport through the cornea. The apparatus is a lucite cell, divided in two compartments by a clamped rabbit cornea. Physiological conditions are ensured by a supply of oxygenated perfusion medium. They are monitored by electrical conductivity and corneal thickness measurements. Reliability of the system was tested in a set of experiments.
