    • The present invention provides new compositions and methods for treating and/or reversing organophosphate intoxication, manifested by both cholinergic and non-cholinergic crisis, in a mammal resulting from exposure to organophosphate compounds. The neurosteroidal compounds of this invention are those having the general structural formula of pregnane, androstane, 19-norandrostanes, and norpregnane with further moieties as defined herein. These compounds include, but are not limited to, ganaxolone, pregnanolone, and androstanediol and their analogs, salts and prodrugs. The present invention further relates to combining a therapeutically effective amount of a neurosteroidal compound with a standard organophosphate antidote (e.g. atropine, pralidoxime). The data suggests that neurosteroids are effective or more effective than benzodiazepines, whether given earlier or later than 40-min (up to several hours) after organophosphate compound exposure. Neurosteroids are effective to attenuate long-term neuropsychiatric deficits caused by organophosphate exposure.
    • 本发明提供了用于治疗和/或逆转由有机磷酸酯化合物暴露引起的哺乳动物中胆碱能和非胆碱能危机所表现的有机磷酸酯中毒的新组合物和方法。 本发明的神经类固醇化合物是具有通用结构式为孕甾烷,雄甾烷,19-去甲雄烷和具有本文所定义的其它部分的去甲孕烷的那些化合物。 这些化合物包括但不限于加奈索酮,怀孕酮和雄甾烷二醇及其类似物,盐和前体药物。 本发明还涉及将治疗有效量的神经甾体化合物与标准有机磷酸盐解毒剂(例如阿托品,哌拉西肟)组合。 数据表明,神经类固醇比苯二氮卓有效或更有效,不论是在有机磷酸酯化合物暴露之后早于或晚于40分钟(直至数小时)给予。 神经甾体可有效减轻由有机磷暴露引起的长期神经精神缺陷。
