The purpose of this study was to characterize the ocular pharmacokinetics of a beta blocker, tilisolol, after instillation into anesthetized rabbits using a mathematical model including a diffusion process. The samples were analyzed by HPLC. Anesthetized rabbit was used as a model of tear secretion deficiency. Anesthetized rabbits showed higher drug concentration in the tear fluid and aqueous humor after instillation than unanesthetized rabbits. A mathematical model including a diffusion process and in vivo penetration parameters well described the concentrations of tilisolol in the aqueous humor after instillation in anesthetized rabbits.
