Inclusion complexes of hydroxypropyl, hydroxyethyl, glucosyl, maltosyl and maltotriosyl derivatives of .beta.- and .gamma.-cyclodextrin with the reduced, biooxidizable, blood-brain barrier penetrating, lipoidal forms of dihydropyridine.revreaction.pyridinium salt redox systems for brain-targeted drug delivery provide a means for stabilizing the redox systems, particularly against oxidation. The redox inclusion complexes also provide a means for decreasing initial drug concentrations in the lungs after administration of the systems, leading to decreased toxicity. In selected instances, complexation results in substantially improved water solubility of the redox systems as well.
羟丙基、羟乙基、葡萄糖基、麦芽糖基和麦芽三糖基的β-和γ-环糊精的包含物与二氢吡啶酰盐氧化还原体系的还原、可生物氧化、穿越血脑屏障的脂质形式形成的复合物,用于脑定向药物传递,提供了一种稳定氧化还原体系的手段,特别是对抗氧化反应。氧化还原的包含物复合物还提供了一种减少系统给药后肺部初始药物浓度的手段,从而降低毒性。在某些情况下,复合物化可显著提高氧化还原体系的水溶性。
