Hydroxylated nebivolol metabolites increase NO release from human endothelial cell preparations in a concentration dependent fashion following acute administration. In addition, hydroxylated nebivolol metabolites, including but not limited to 4-hydroxy-6,6′difluoro-, 4-hydroxy-5-phenol-6,6′difluoro-, and 4-hydroxy-8-pheno-6,6′difluoro-, have the ability to increase the capacity for NO release in human endothelial cells following chronic administration. This invention provides hydroxylated nebivolol metabolites and compositions comprising nebivolol and/or at least one hydroxylated metabolite of nebivolol and/or at least one additional compound used to treat cardiovascular diseases or a pharmaceutically acceptable salt thereof. In addition, this invention provides methods of treating and/or preventing vascular diseases by administering at least one hydroxylated metabolite of nebivolol that is capable of releasing a therapeutically effective amount of nitric oxide to a targeted site affected by the vascular disease. Also, this invention is directed to the treatment and/or prevention of migraine headaches administering at least one hydroxylated metabolite of nebivolol. This invention may also be used in conjunction with or as a single treatment of metabolic syndrome disorders.
羟基化奈必洛尔代谢物在急性给药后以浓度依赖性方式增加人内皮细胞制剂的一氧化氮释放。此外,羟基化奈必洛尔代谢物,包括但不限于4-羟基-6,6'-二氟代-、4-羟基-5-苯酚-6,6'-二氟代-和4-羟基-8-苯并-6,6'-二氟代-,在慢性给药后能够增加人内皮细胞的一氧化氮释放能力。本发明提供了羟基化奈必洛尔代谢物和包含奈必洛尔和/或至少一种羟基化奈必洛尔代谢物和/或至少一种用于治疗心血管疾病的附加化合物的组合物,以及可药用的盐。此外,本发明还提供了通过给药至少一种能够释放治疗有效量的一氧化氮到受血管疾病影响的靶向部位的羟基化奈必洛尔代谢物来治疗和/或预防血管疾病的方法。本发明还涉及通过给药至少一种羟基化奈必洛尔代谢物来治疗和/或预防偏头痛。本发明还可以与治疗代谢综合征障碍的其他治疗联合使用,或作为单一治疗。
