The disclosure provides a method of treating a patient having postpartum depression, premenstrual dysphoric disorder, menopausal depression, or delirium tremens comprising administering an effective amount of an injectable neurosteroid formulation to the patient. In certain embodiments the injectable neurosteroid formulation is an injectable ganaxolone formulation. Two types of injectable neurosteroid formulations may be used in the disclosed methods. The first such formulation is an injectable formulation containing ganaxolone and sulfobutyl ether β-cyclodextrin in a 1:1 inclusion complex. The second such formulation is an injectable neurosteroid formulation comprising a neurosteroid, preferably ganaxolone, but which may be a neurosteroid selected from allopregnanolone, ganaxolone, alphaxalone, alphadolone, hydroxydione, minaxolone, pregnanolone, tetrahydrocorticosterone, and combinations of the foregoing; a surface stabilizer selected from hydroxyl ethyl starch, dextran, and povidone; and a surfactant.

Steroid derivative regulators, a method for preparing the same, and uses thereof are described. Specifically, a compound of formula (I), a preparation method therefor, a pharmaceutical composition containing the compound, and uses thereof as a regulator the of GABA.sub.A receptor for treating depression, convulsion, Parkinson's disease, and nervous system diseases are described, wherein the substituents of the formula (I) are as defined in the description.

Such compounds are contemplated useful for the prevention and treatment of a variety of CNS-related conditions, for example, treatment of sleep disorders, mood disorders, schizophrenia spectrum disorders, convulsive disorders, disorders of memory and/or cognition, movement disorders, personality disorders, autism spectrum disorders, pain, traumatic brain injury, vascular diseases, substance abuse disorders and/or withdrawal syndromes, and tinnitus.

Provided herein are 19-nor C3,3-disubstituted steroids of Formula (I):

##STR00001##

and pharmaceutically acceptable salts thereof; wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4 are as defined herein, and A is a heteroaryl ring system comprising 3 or 4 nitrogens as defined herein. Such compounds are contemplated useful for the prevention and treatment of a variety of CNS-related conditions, for example, treatment of sleep disorders, mood disorders, schizophrenia spectrum disorders, convulsive disorders, disorders of memory and/or cognition, movement disorders, personality disorders, autism spectrum disorders, pain, traumatic brain injury, vascular diseases, substance abuse disorders and/or withdrawal syndromes, and tinnitus.

The present invention relates to aseptic suspensions, physically stable and injectable through a 25G needle or thinner, comprising crystalline, non-micronized 3-beta-hydroxy-5-alpha-pregnan-20-one particles, a mixture of acylglycerols and cholesterol, processes for preparing crystalline, non-micronized, 3-beta-hydroxy-5-alpha-pregnan-20-one suitable for such suspensions, as well as methods for manufacturing such suspensions.

The present application relates to novel compounds that are prodrugs of brexanolone, ganaxolone and zuranolone, pharmaceutical compositions comprising one or more compounds disclosed herein and salts thereof, and a pharmaceutically acceptable excipient, and use of the compounds disclosed herein and salts thereof for treating diseases or conditions related to GABA.sub.A receptor function, such as major depression disorder (MDD) and postpartum depression (PPD), in mammals and especially in humans.

The present invention falls within the field of pharmaceutical chemistry, and relates to a method for preparing a steroid derivative FXR agonist and relevant intermediates. In particular, the present invention relates to a method for preparing a compound of formula I, comprising reacting a compound of formula 8 with a compound of formula 9 to obtain a compound of formula 10, obtaining a compound of formula 11 from a reaction of the compound of formula 10, and obtaining the compound of formula I from a reaction of the compound of formula 11, as well as the intermediates used, the methods for preparing the intermediates and the use of the intermediates. The reaction conditions of the preparation method are mild, and some of the steps can convert multiple groups simultaneously, thereby effectively shortening the sequence of steps. The preparation method is suitable for industrialized production. ##STR00001##

Disclosed are a crystalline or amorphous form of steroid derivative FXR agonist (formula I), and a preparation method therefor, and a crystalline composition and pharmaceutical composition comprising the crystalline or amorphous form, and the use of same in the preparation of a drug for treating or preventing various conditions associated with FXR. ##STR00001##
