Definitions
- the present invention relates to a composition which comprises a first component (a) which is (7 ⁇ -3-NN-dicyclobutylamino-8-fluoro-3,4-dihydro-2H-l-benzopyran-5- carboxamide hydrogen (2i?,3i?)-tartrate monohydrate and a second component (b) which is a 5- ⁇ T reuptake inhibitor excluding citalopram and paroxetine.
- 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.
- 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.
- WO 96/33710 is disclosed the combination of the compound (7?)-5-carbamoyl-8-fluoro- 3-NN-dicyclobutylamino-3,4-dihydro-2H-l-benzopyran which has high affinity to 5- ⁇ T receptors and antagonizes 5-HTj A mediated responses, with a serotonin reuptake inhibitor.
- 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 t ⁇ -3-NN-dicyclobutylamino-8-fluoro-3,4- dihydro-2H-l-benzopyran-5-carboxamide hydrogen (2i?,3i?)-tartrate monohydrate and a second component (b) which is a 5- ⁇ T reuptake inhibitor excluding citalopram and paroxetine.
- Said composition attains a faster onset of action and consequently, provides a more efficacious treatment of the patients suffering from affective disorders, particularly depression.
- 3-NN-dicyclobutylamino-8-fluoro-3,4-dihydro-2H-l-benzopyran-5-carboxamide hydrogen (2i?,3R)-tartrate monohydrate possesses a high affinity to the specific subgroup of 5- ⁇ T I A receptor in the C ⁇ S and acts as an antagonist on that 5-HT ⁇ A receptor, and also shows favourable bioavailability after oral administration.
- SSRIs 5-HT reuptake inhibitors
- SSRIs Known 5-HT reuptake inhibitors
- component (b) in the combination according to the invention is not limited only to those SSRIs.
- composition according to the present invention may exist in one pharmaceutical formulation comprising the component (a) and component (b), or in two different pharmaceutical formulations, one for component (a) and one for component (b).
- the pharmaceutical formulation may be in the form of tablets or capsules, powders, mixtures, solutions or other suitable pharmaceutical formulation forms such as patches and nasal formulations.
- composition of the present invention can be prepared such that component (a) is incorporated into the same pharmaceutical formulation as component (b) by e.g. mixing in a conventional way.
- the present invention also includes a method of improving the onset of therapeutic action by concomitant administration of a composition comprising of (R)-3-N,N- dicyclobutylamino-8-fluoro-3 ,4-dihydro-2H- 1 -benzopyran-5-carboxamide hydrogen (2#,3#)-tartrate monohydrate and a 5-HT reuptake inbibitor excluding citalopram and paroxetine.
- a further embodiment of the present invention is a kit containing a dosage unit of of (R)-3- NN-dicyclobutylamino-8-fluoro-3,4-dihydro-2H- l-benzopyran-5-carboxamide hydrogen (2i?,3i?)-tartrate monohydrate and a dosage unit of a 5-HT reuptake inbibitor excluding citalopram and paroxetine, optionally with instructions for use.
- the compounds in the composition will normally be administered orally, rectally, transdermally, nasally or by injection, in the form of pharmaceutical formulations comprising the active ingredients in a pharmaceutically acceptable dosage form .
- the dosage form may be a solid, semisolid or liquid formulation.
- the active substances will constitute between 0.1 and 99% by weight of the formulation, more specifically between 0.5 and 20% by weight for formulations intended for injection and between 0.2 and 50% by weight for formulations suitable for oral administration.
- the pharmaceutical formulation comprises the active ingredients, optionally in association with adjuvants, excipients e.g. diluents, and/or inert carriers.
- the selected compounds may be mixed with a solid excipient, e.g. lactose, saccharose, sorbitol, mannitol, starches such as potato starch, corn starch or amylopectin, cellulose derivatives, a binder such as gelatin or poly- vinylpyrrolidone, disintegrants e.g. sodium starch glycolate, cross-linked PVP and cross- caramellose sodium; a lubricant such as magnesium stearate, calcium stearate, polyethylene glycol, waxes, paraffin, and the like, and an antisticking agent such as talc or colloidal silicon dioxide, and then compressed into tablets.
- a solid excipient e.g. lactose, saccharose, sorbitol, mannitol, starches such as potato starch, corn starch or amylopectin, cellulose derivatives, a binder such as gelatin or poly- vinylpyrrolidone, disintegrants e.g. sodium starch
- the cores may be coated with a polymer known to the man skilled in the art e.g. HPMC, HC or other cellulose derivatives or PVP, wherein the polymer is dissolved in water or a readily volatile organic solvent or mixture of organic solvents.
- a polymer known to the man skilled in the art e.g. HPMC, HC or other cellulose derivatives or PVP, wherein the polymer is dissolved in water or a readily volatile organic solvent or mixture of organic solvents.
- the tablets can be coated with a concentrated sugar solution which may contain e.g. gum arabic, gelatine, talcum, titanium dioxide, and the like.
- Dyestuffs may be added to these coatings for instance in order to readily distinguish between tablets containing different active substances or different amounts of the active compounds.
- the active substances may be admixed with e.g. a vegetable oil or polyethylene glycol.
- Hard gelatin capsules may contain granules of the active substances using any of the above mentioned excipients for tablets e.g. lactose, saccharose, sorbitol, mannitol, starches (e.g. potato starch, corn starch or amylopectin), cellulose derivatives, plasticizers, polyetheneglycol, waxes, lipids or gelatin. Also liquids or semisolids of the drug can be filled into hard gelatin capsules.
- Dosage units for rectal application can be solutions or suspensions or can be prepared in the form of suppositories comprising the active substances in a mixture with a neutral fatty base, or gelatin rectal capsules comprising the active substances in admixture with vegetable oil or paraffin oil.
- Liquid formulations for oral application may be in the form of solutions, syrups or suspensions, for example solutions containing from about 0.2% to about 20% by weight of the active substances herein described, the balance being sugar and a mixture of ethanol, water, glycerol and propylene glycol.
