title: Intraocular penetration of CT-112, an aldose reductase inhibitor, following topical instillation.
abstract: Intraocular penetration of 5-(3-ethoxy-4-pentyloxyphenyl)thiazolidine-2,4-dione (CT-112), an aldose reductase inhibitor, was investigated in rabbits following topical instillation. The concentration of CT-112 in corneal epithelium, stroma, endothelium, lens, and aqueous humor, was sequentially determined by high-performance liquid chromatography. CT-112 peaked in the corneal epithelium, stroma, endothelium and aqueous humor in 30 minutes following instillation, then gradually diminished time-dependently over a period of 24 hours. CT-112 remained detectable in the lens up to 24 hours, with a peak concentration at 2 hours after instillation.
