代谢
在眼内应用后,异丙酯前列腺素通过角膜中的酯酶水解为其生物活性代谢物,即前列腺素游离酸。然后,前列腺素游离酸通过ε-或β-氧化代谢为几个分子量更低、极性更高的无活性代谢物。没有发现次要的共轭作用,并且未观察到对肝微粒体酶活性的显著影响。
After ocular application, unoprostone isopropyl is hydrolyzed by esterases in the cornea to its biological active metabolite, unoprostone free acid. Unoprostone free acid is then metabolized to several inactive metabolites with lower molecular weight and increased polarity via ε- or β-oxidation. No secondary conjugation is found and no significant effect on hepatic microsomal enzyme activity has been observed.
