The invention relates to a pharmacological effect of a compound functioning as PPARγ agonist on a corneal epithelial barrier function. Since the PPARγ agonist, such as rivoglitazone, DRF-2593, GW-544 and BMS-298585, exhibits an excellent enhancing effect on the corneal epithelial barrier function in an enhancement test of corneal epithelial barrier function, it is useful as a preventive or therapeutic agent for ocular infection, ocular discomfort and the like attributed to a decrease in the corneal epithelial barrier function. In addition, the PPARγ agonist can enhance the corneal epithelial barrier function in a diabetes patient, a patient with a decrease in the corneal epithelial barrier function due to aging, and a patient who underwent refractive surgery, such as PRK (photorefractive keratectomy) and LASIK (laser in situ keratomileusis), and cataract surgery.
本发明涉及一种具有
PPARγ 激动剂作用的化合物对角膜上皮屏障功能的药理作用。由于
PPARγ 激动剂(如利伏格列酮、DRF-2593、GW-544 和 BMS-298585)在角膜上皮屏障功能增强试验中对角膜上皮屏障功能有极好的增强作用,因此可作为预防或治疗因角膜上皮屏障功能降低而引起的眼部感染、眼部不适等的药物。此外,
PPARγ 激动剂还能增强糖尿病患者、因衰老导致角膜上皮屏障功能下降的患者、接受过 PRK(光屈光性角膜切除术)和
LASIK(激光原位角膜磨镶术)等屈光手术以及白内障手术的患者的角膜上皮屏障功能。
