The disclosed subject matter provides certain polymorphic forms of Compound (I) as well as pharmaceutical compositions comprising Compound (I) or such polymorphic forms, and methods of using or making such compounds and pharmaceutical compositions. It has now been discovered that Compound (I) can exist in multiple crystalline forms (polymorphs). One particular crystalline form, Form II, has been found to be more thermodynamically stable and, thus, likely more suitable for bulk preparation and handling than other polymorphic forms. Efficient and economic methods have been developed to prepare Compound (I) and Form II in high purity on a large scale. In animal studies, Form II has demonstrated safety and efficacy in treating depressive disorders and, when micronized, improved absorption compared to non-micronized Form II.
所公开的主题提供了化合物 (I) 的某些多晶型以及包含化合物 (I) 或此类多晶型的药物组合物,以及使用或制造此类化合物和药物组合物的方法。现已发现,化合物(I)可以多种结晶形式(多晶型)存在。其中一种特殊的结晶形态,即形态 II,已被发现在热力学上更为稳定,因此可能比其他多晶形态更适合批量制备和处理。目前已开发出高效、经济的方法来大规模制备高纯度的化合物 (I) 和形式 II。在动物实验中,形式 II 在治疗抑郁障碍方面具有安全性和有效性,与非微粉化形式 II 相比,微粉化形式 II 的吸收率更高。
