治疗类别名称
前列腺素F2α衍生物，青光眼和高眼压症治疗剂
药理作用
拉坦前列腺素是一种新型苯基替代的丙基酯前列腺素F2α，为选择性F2α受体激动药。它是一种无活性但能迅速渗透到角膜里的物质，在角膜和血浆中可水解为具有活性的游离酸。它能增加房水通过眼角素层的流出量，用药量小，但促进房水流出量大，药液能渗透到眼球脉络膜上层，具有良好降眼压效果。本品还可使青光眼患者通常会堵塞的眼球小梁筛网结构通畅。
药动学
本品在角膜中水解为游离酸，这种游离酸从角膜扩散出来并进入房水中，约2h可达到血药峰值。3～4h后眼压开始下降，8～12h达到最大下降幅度，维持24h眼压不升高。该药在房水流出时被排出，半衰期约为2h。通过结膜或黏膜产生全身吸收，被吸收的药物在血液循环系统，经肝代谢后主要随尿排泄。
适应证
适用于开角型青光眼，以及用其他药物难以治疗或耐受的眼压过高患者的局部治疗。
禁忌证
1.孕妇、哺乳期妇女禁用。
2.严重哮喘或眼睛发炎充血期间等患者禁用。
注意事项
1.儿童不推荐使用。
2.本品不适用于治疗闭角型或先天性青光眼，色素沉着性青光眼以及假晶状体的开角型青光眼。
3.本品与其他抗青光眼药物联合使用具有协同作用，所用其他滴眼药，应至少间隔5min滴用。
4.佩戴角膜接触镜者应先摘掉镜片，滴入药物15min后才能戴上镜片。
不良反应
本品通常耐受良好，偶见视力模糊、烧灼痛、刺痛、结膜充血、短暂点状角膜糜烂和异物感。某些患者还会出现虹膜的棕色色素沉着(6个月后有7%，12个月后达16%)。色素增加在有绿棕色、蓝灰棕色或黄棕色虹膜的人种较为多见，在纯蓝色、蓝灰色或绿色的人种中则较罕见。这是由于黑色素形成的刺激引起的，停药后即可停止进展，但明显不能恢复。
