Definitions

  • the present invention relates to a composition which comprises a first component (a) which is R 3-N,N-dicyclobutylamino-8-fluoro-3,4-dihydro-2H- 1 -benzopyran-5- carboxamide hydrogen (2R,3R)-tartrate monohydrate and a second component (b) which is l-[3-(dimethylamino)propyl]-l-(p-fluorophenyl)-5-phthalancarbonitrile, as the racemate or an enantiomer thereof, in the form of the free base, or a pharmaceutically acceptable salt and/or solvate thereof.
  • a first component (a) which is R 3-N,N-dicyclobutylamino-8-fluoro-3,4-dihydro-2H- 1 -benzopyran-5- carboxamide hydrogen (2R,3R)-tartrate monohydrate
  • a second component (b) which is l-[3-(dimethylamino)propyl
  • the present invention also relates to a process for the preparation of the inventive composition, pharmaceutical formulations containing said composition and to the use of said composition either by concomitant administration or by separate administration as an improvement of the treatment of affective disorders such as depression, anxiety, obsessive compulsive disorder (OCD), etc.
  • affective disorders such as depression, anxiety, obsessive compulsive disorder (OCD), etc.
  • antidepressants take 2-4 weeks to reach full clinical effect. In contrast, the side effects occur immediately. Thus, slow onset of action of antidepressants leads to a vulnerable period for patients in which they experience the side effects, but not the therapeutic effects of drugs. There is often a heavy burden on the treating physician to persuade the patient to continue with the treatment during this period. Furthermore, in suicidal patients, as the onset of action is gradual, initiative may be regained without the experiencing of full reversal of symptoms, leaving a window of risk for suicide and a frequent requirement for hospitalization.
  • the present invention is directed to a new composition
  • a new composition comprising of a first component (a) which is the specific 5-HT ⁇ antagonist (R ⁇ -3-N,N-dicyclobutylamino-8-fluoro-3,4- dihydro-2H-l-benzopyran-5-carboxamide hydrogen (2R,3R)-tartrate monohydrate and a second component (b) which is l-[3-(dimethylamino)propyl]-l-(p-fluorophenyl)-5- phthalancarbonitrile, as the racemate or an enantiomer thereof, in the form of the free base, or a pharmaceutically acceptable salt and/or solvate thereof, which is a 5- ⁇ T reuptake inhibitor.
  • Said composition attains a faster onset of action and consequently, provides a more efficacious treatment of the patients suffering from affective disorders, particularly depression.
