An object of the present invention is to provide a compound that can be used as a more superior therapeutic agent for central nervous system diseases. The present invention provides a dihydrate of 7-[4-(4-benzo[b]thiophen-4-yl-piperazin-1-yl)butoxy]-1H-quinolin-2-one or of a salt thereof, and a process for producing the same

The present invention provides a method for safe and efficacious administration of esketamine.

The present invention provides spiro-oxazolones, which act as V1a receptor modulators, and in particular as V1a receptor antagonists, their manufacture, pharmaceutical compositions containing them and their use as medicaments. The present compounds are useful as therapeutics acting peripherally and centrally in the conditions of inappropriate secretion of vasopressin, anxiety, depressive disorders, obsessive compulsive disorder, autistic spectrum disorders, schizophrenia, aggressive behavior and phase shift sleep disorders, in particular jetlag.

Novel cyclic peptides, cyclic peptide conjugates and compositions containing them for treating neurological diseases in a subject include an Odorranalectin (OL) sequence or modified OL sequence as a scaffold and a biologically active peptide or protein and/or therapeutic agent conjugated thereto. Methods of treatment of neurological diseases are based on intranasal delivery of a cyclic peptide or cyclic peptide conjugate as described herein. Combinatorial libraries that include a plurality of cyclic peptides have also been developed and can be used to screen for a ligand(s) for a receptor of interest.

The purpose of the present invention is to provide: a therapeutic agent or a recurrence preventive agent for serotonergic system- or dopaminergic system-related diseases, in particular, mental dysfunction symptoms and other non-motor symptoms of Parkinson's disease; and a method for treating the aforesaid symptoms or preventing the recurrence of the same. A compound represented by formula (1) [wherein each symbol is as defined in the description] or a pharmaceutically acceptable salt thereof can exhibit an effect of treating serotonergic system- or dopaminergic system-related diseases, in particular, mental dysfunction symptoms and other non-motor symptoms of Parkinson's disease and/or an effect of preventing the recurrence of the same. ##STR00001##

Disclosed are compounds having potency in the modulation of NMDA receptor activity. Such compounds can be used in the treatment of conditions such as depression and related disorders as well as other disorders.

Novel compounds having a D3 receptor antagonistic effect are provided. The compound represented by Formula (IA)′: ##STR00001##
wherein A is S or O; R.sup.1a is substituted or unsubstituted alkyloxy or the like, R.sup.2a to R.sup.2d are each independently hydrogen atoms or the like, ring B is a 4- to 8-membered non-aromatic carbocycle or the like, R.sup.3 is each independently halogen or the like, r is an integer of 0 to 4, R.sup.4 is substituted or unsubstituted aromatic heterocyclyl or the like,
or a pharmaceutically acceptable salt thereof.

The present invention relates to a cannabinoid containing oral solution. Preferably the cannabinoid is cannabidiol (CBD), cannabidivarin (CBDV) or cannabidiol-C4 (CBD-C4). More preferably the CBD, CBDV or CBD-C4 is present at a concentration of between 25 and 75 mg/ml. More preferably still the CBD, CBDV or CBD-C4 is present at a concentration of 50 mg/ml. In a further embodiment the oral solution is formulated with one or more edible oils. Preferably the edible oil is sesame oil. It is a preferred embodiment of the invention that the oral formulation comprises a low concentration of ethanol.

An anti-aggregation agent of the present invention contains, as an anti-aggregation ingredient, at least one selected from the group consisting of polyoxyethylene cetyl ether, polyoxyethylene sorbitan fatty acid esters, polyoxyethylene polyoxypropylene glycols having an average molecular weight of 3000 to 13000 and combinations thereof. According to the present invention, in a container whose inner wall is treated with silicone oil, aggregation of a poorly water-soluble drug caused by the silicone oil can be prevented.
