ABSTRACT:
This application is a 371 of PCT/FR00/01084, filed Apr. 25, 2000.
The present invention relates to a novel use of saredutant.
Saredutant is the International Nonproprietary Name (I.N.N.) for (S)-(−)-N-methyl-N-[4-(4-acetylamino-4-phenylpiperid-1-yl)-2-(3,4-dichloro-phenyl)butyl]benzamide, of formula:
This compound and its pharmaceutically acceptable salts are described in patent EP 0 474 561 B1 and in U.S. Pat No. 5,236,921.
These compounds are described as antagonists of neurokinin A receptors and may be useful in any neurokinin A-dependent pathology and more particularly in neurogenic inflammations of the respiratory pathways. These compounds have also been described as powerful and selective non-peptide antagonists of the NK
2
receptors of neurokinin A (Life Sciences, 1992, 50 (15), PL101-PL106).
It has now been found that saredutant and its pharmaceutically acceptable salts are useful in the treatment or prevention of all mood disorders, adaptation disorders and mixed anxiety-depression disorders, whether or not these disorders are induced by events of life or stressful events. The expression “mood disorder” means major depressive disorders, dysthymic disorders or bipolar disorders.
Thus, according to one of its aspects, a subject of the present invention is the use of saredutant and of its pharmaceutically acceptable salts for the preparation of medicinal products that are useful in the treatment or prevention of all mood disorders, adaptation disorders or mixed anxiety-depression disorders.
In particular, a subject of the present invention is the use of saredutant and of its pharmaceutically acceptable salts for the preparation of medicinal products that are useful in the treatment or prevention of all mood disorders, more particularly of major depressive disorders, dysthymic disorders or bipolar disorders.
In particular also, a subject of the present invention is the use of saredutant and of its pharmaceutically acceptable salts for the preparation of medicinal products that are useful in the treatment or prevention of adaptation disorders.
Finally, in particular, a subject of the present invention is the use of saredutant and of its pharmaceutically acceptable salts for the preparation of medicinal products that are useful in the treatment or prevention of mixed anxiety-depression disorders.
According to another of its aspects, a subject of the present invention is a method for treating or preventing all mood disorders, adaptation disorders or mixed anxiety-depression disorders by administration of a suitable dose of saredutant or of one of its pharmaceutically acceptable salts.
Saredutant and its pharmaceutically acceptable salts are prepared according to the process described in patent EP 0 474 561 B1 or that described in patent EP 0 698 601 B1.
The salts of the compound of formula (I) are the salts with conventional pharmaceutically acceptable inorganic or organic acids, such as the hydrochloride, hydrobromide, sulphate, hydrogen sulphate, dihydrogen phosphate, methanesulphonate, methyl sulphate, acetate, oxalate, maleate, fumarate, succinate, 2-naphthalenesulphonate, glyconate, gluconate, citrate, isethionate, benzenesulphonate or para-toluenesulphonate.
For their use as medicinal products, the compound of formula (I) and its pharmaceutically acceptable salts are generally administered in dosage units. The said dosage units are preferably formulated in pharmaceutical compositions in which the active principle is mixed with a pharmaceutical excipient.
In the pharmaceutical compositions of the present invention for oral, sublingual, inhaled, subcutaneous, intramuscular, intravenous, transdermal, local or rectal administration, the active principle, alone or in combination with another active principle, can be administered in unit administration form, mixed with conventional pharmaceutical supports, to animals and to human beings. The appropriate unit administration forms comprise oral forms such as tablets, gel capsules, powders, granules and oral solutions or suspensions, sublingual and buccal administration forms, aerosols, topical administration forms, implants, subcutaneous, transdermal, intramuscular, intravenous or intranasal administration forms and rectal administration forms.
The daily dose of the compound of formula (I) is from 0.05 to 5 mg/kg, advantageously from 1 to 2.5 mg/kg, preferably from 2 to 2.5 mg/kg, to be administered in one or more dosage intakes. The compound of formula (I) and its salts are generally formulated in a dosage unit containing from 2.5 to 500 mg, advantageously from 50 to 250 mg and preferably from 100 to 250 mg, of active principle per dosage unit, to be administered in one, two or more dosage intakes at the same time, according to need. Although these doses are examples of average situations, there may be special cases in which higher or lower doses are appropriate, and such doses also form part of the invention. According to usual practice, the dose which is appropriate for each patient is determined by the doctor according to the mode of administration, the age, the weight and the response of the said patient.
When a solid composition in tablet form is prepared, a pharmaceutical vehicle is added to the micronized or non-micronized active principle, which vehicle can be composed of diluents such as, for example, lactose, microcrystalline cellulose, starch and formulation additives such as binders (polyvinylpyrrolidone, hydroxypropylmethylcellulose, etc.), flow agents such as silica, lubricants such as magnesium stearate, stearic acid, glyceryl tribehenate or sodium stearylfumarate.
Wetting agents or surfactants such as sodium lauryl sulphate can be added to the formulation.
The tablets can be prepared by various techniques: direct tabletting, dry granulation, wet granulation, hot melting.
The tablets can be plain or sugar-coated (for example coated with sucrose) or coated with various polymers or other suitable materials.
The tablets can undergo immediate, delayed or sustained release by preparing polymer matrices or by using specific polymers in the film-coating operation.
A preparation as a gel capsule is obtained by simply mixing the active principle with dry pharmaceutical vehicles (simple mixing or dry granulation, wet granulation or hot melting), liquid or semi-solid pharmaceutical vehicles.
The gel capsules can be soft or hard, and film-coated or otherwise, so as to have immediate, sustained or delayed activity (for example via an enteric form).
A preparation in syrup or elixir form can contain the active principle together with a sweetener, preferably a calorie-free sweetener, methylparaben and propylparaben as antiseptic, as well as a flavour enhancer and a suitable colorant.
The water-dispersible powders or granules can contain the active principle as a mixture with dispersing agents, wetting agents or suspending agents, such as polyvinylpyrrolidone, as well as with sweeteners or flavour enhancers.
For rectal administration, use is made of suppositories which are prepared with binders that melt at the rectal temperature, for example cocoa butter or polyethylene glycols.
For parenteral or intranasal administration, aqueous suspensions, isotonic saline solutions or sterile, injectable solutions which contain pharmacologically compatible dispersing agents and/or solubilizing agents, for example propylene glycol or butylene glycol, are used.
Thus, to prepare an aqueous solution for intravenous injection, it is possible to use a co-solvent such as, for example, an alcohol such as ethanol or a glycol such as polyethylene glycol or propylene glycol, and a hydrophilic surfactant such as Tween® 80. To prepare an oily solution for intramuscular injection, the active principle can be dissolved with a triglyceride or a glycerol ester.
For local administration, creams, ointments, gels or eye drops can be used.
For transdermal administration, patches can be used in multilayer or reservoir form in which the active principle can be in alcoholic solution.
For administration by inhalation, an aerosol is used containi
