    • Methods and compositions are disclosed utilizing the optically pure R(+) isomer of ondansetron. This compound is a potent drug for the treatment of nausea and vomiting associated with chemotherapy and radiation therapy, while avoiding the concomitant liability of adverse effects associated with the racemic mixture of ondansetron. The R(+) isomer of ondansetron is also useful for the treatment of behavioral disorders such as mood anxiety and schizophrenia, and such other conditions as may be related to R(+) ondansetron's activity as a competitive antagonist of serotonin receptor subtype 5-HT3 such as disorders of gastrointestinal motility, depression, migraine, and as an aid for alcohol withdrawal, nicotine withdrawal, and drug (benzodiazepine et al.) withdrawal, without the concomitant liability of adverse effects associated with the racemic mixture of ondansetron. Furthermore, the R(+) isomer of ondansetron is also useful for the treatment of cognitive disorders such as dementia or age-associated memory impairment, while avoiding the concomitant liability of adverse effects associated with the racemic mixture of ondansetron.
    • 公开了使用昂丹司琼的光学纯的R(+)异构体的方法和组合物。 该化合物是用于治疗与化疗和放射治疗相关的恶心和呕吐的有效药物,同时避免与昂丹司琼外消旋混合物相关的副作用的伴随责任。 昂丹司琼的R(+)异构体也可用于治疗诸如情绪焦虑和精神分裂症等行为障碍,以及可能与R(+)昂丹司琼活性作为5-羟色胺受体亚型5-HT3的竞争性拮抗剂相关的其他条件 例如消化道运动障碍,抑郁症,偏头痛,以及用于酒精戒断,尼古丁戒断和药物(苯并二氮杂类等)撤离的辅助,而不伴随昂丹司琼外消旋混合物的不良反应。 此外,昂丹司琼的R(+)异构体也可用于治疗诸如痴呆或年龄相关记忆障碍的认知障碍,同时避免与昂丹司琼外消旋混合物相关的副作用的伴随责任。
