Description

Technical Field

[0001] The present invention relates to a pharmaceutical composition, which comprises (1R, 5S)-1-(naphthalen-2-yl)-3-azabicyclo[3.1.0]hexane (centanafadine) or a pharmaceutically acceptable salt thereof as an active ingredient, and also relates to an oral solid preparation comprising the pharmaceutical composition, wherein the oral solid preparation can be administered once a day. Background Art

[0002] (1R,5S)-1-(Naphthalen-2-yl)-3-azabicyclo[3.1.0]hexane, also known as (+)-1-(Naphthalen-2-yl)-3-azabicyclo[3.1.0]hexane, is able to inhibit the reuptake of three biogenic amines: norepinephrine, serotonin, and dopamine (PL1).

[0003] (1R,5S)-1-(naphthalen-2-yl)-3-azabicyclo[3.1.0]hexane is most effective for norepinephrine (NE) reuptake, but 6 times less effective for dopamine (DA) reuptake and 14 times less effective for serotonin (5-HT) reuptake. Therefore, (1R,5S)-1-(naphthalen-2-yl)-3-azabicyclo[3.1.0]hexane is a compound that can be used as an unbalanced triple reuptake inhibitor (TRI). Based on these actions, the compounds of the present invention can be used as therapeutic agents for CNS disorders such as depression, anxiety and attention deficit hyperactivity disorder (ADHD).

[0004] Recently, for the use of drugs in the treatment of CNS disorders such as depression, anxiety and attention deficit hyperactivity disorder (ADHD), once-daily oral administration is recommended. Pharmaceutical compositions suitable for once-daily oral administration have been developed, for example, pharmaceutical preparations comprising a variety of drug-containing granules have been developed, which are prepared with delayed-release (enteric-coated) granules, sustained-release granules and / or immediate-release granules.
