Abstract

In vivo ocular availability of ketorolac was evaluated following ocular instillation of aqueous, oil, and ointment formulations to normal corneas of rabbits and monitoring ketorolac concentration in aqueous humor by HPLC. Compared with aqueous drop, sesame and soybean oil drops of ketorolac provided higher ocular availability followed by ophthalmic ointment. The ointment formulation provided maximum sustained effect. Ketorolac aqueous drop with BAC and EDTA improved the rate of ocular absorption though not the extent.

摘要

通过向兔的正常角膜滴注水性、油性和软膏剂型的酮咯酸,并采用高效液相色谱法监测房水中酮咯酸的浓度,对酮咯酸的体内眼部可利用性进行了评估。与水性滴剂相比,酮咯酸的芝麻油和大豆油滴剂具有更高的眼部可利用性,其次是眼膏。软膏剂型提供了最大的持续效果。含苯扎氯铵和乙二胺四乙酸的酮咯酸水性滴剂提高了眼部吸收速率,但未提高吸收程度。
