代谢
一个单一的代谢物,HW1,其分子量大约为16000道尔顿,在狗和人的药代动力学研究中被检测到。在狗和人体中,HW1分别占母体化合物稳态下的10-20%和40%。然而,有建议称,嵌段聚合物不被代谢,并以原样形式通过尿液和粪便排出,HW1可能是P188高分子量分布的一个组成部分,由于其清除率较低,在血浆中浓缩。
A single metabolite, HW1, with a molecular weight of approximately 16000 Daltons was detected in a pharmacokinetic study in dogs and man. HW1 was present in 10-20 and 40% of the parent compound at steady state in dogs and humans, respectively. However, it is suggested that block polymers are not metabolized and are excreted unchanged in the urine and feces, and HW1 may be a component of the higher molecular weight distribution of P188 that concentrates in the plasma due to its lower clearance rate.
