Definitions
- the present invention relates to a new therapeutic application of riluzole (6-trifluoromethoxy-2-amino-benzothiazole) or the pharmaceutically acceptable salts of this compound.
- Riluzole is useful as an anticonvulsant, anxiolytic and hypnotic drug (patent EP 50551), in the treatment of schizophrenia (EP 305276), in the treatment of sleep disorders and depression (EP 305277), in the treatment of cerebrovascular disorders and as an anesthetic (EP 282971).
- Radioremediation is useful in X-ray therapy, particularly in the treatment of cancer and against other sources of harmful radiation such as those encountered by people in areas bordering on nuclear explosions.
- the activity of the product has been demonstrated on the rhinencephalon of young rats subjected to a global gamma irradiation.
- the irradiation is carried out using a gamma ray source, Cobalt 60.
- the animals used are male rats of Sprague Dawley strain weighing 28 to 33 g aged 15 days which are placed in an aerated plexiglass containment box undergoing a rotation of 180 ° in order to carry out global and homogeneous irradiations in a single dose of 1 , 5 and 2.5 Gy with a dose rate of 0.2 Gy per minute.
- the survival time between irradiation and sacrifice is 6 hours. All the animals are fixed by intra-aortic infusion of a fixing liquid composed of 1% paraformaldehyde, 1% glutaraldehyde and 0.05% calcium chloride in a 0.4M phosphate buffer of pH 7.3.
- the product to be studied is administered intraperitoneally at doses of 1, 2, 4 and 8 mg / kg 20 minutes after irradiation (at the start of pycnosis).
- salts with mineral acids such as hydrochloride, sulfate, nitrate, phosphate or organic salts such as acetate, propionate, succinate, oxalate, benzoate, fumarate, maleate, methanesulfonate, isethionate, theophillin- acetate, salicylate, phenolphthalinate, methylene-bis- ⁇ -oxynaphthoate or substitution derivatives of these derivatives.
- mineral acids such as hydrochloride, sulfate, nitrate, phosphate or organic salts such as acetate, propionate, succinate, oxalate, benzoate, fumarate, maleate, methanesulfonate, isethionate, theophillin- acetate, salicylate, phenolphthalinate, methylene-bis- ⁇ -oxynaphthoate or substitution derivatives of these derivatives.
- the medicaments consist of at least riluzole in free form or in the form of an addition salt with a pharmaceutically acceptable acid, in the pure state or in the form of a composition in which it is associated with any other pharmaceutical product. compatible, may be inert or physiologically active.
- the medicaments according to the invention can be used orally or parenterally.
- solid compositions for oral administration tablets, pills, powders (gelatin capsules, cachets) or granules can be used.
- the active principle according to the invention is mixed with one or more inert diluents, such as starch, cellulose, sucrose, lactose or silica, under a stream of argon.
- These compositions can also comprise substances other than diluents, for example one or more lubricants such as magnesium stearate or talc, a dye, a coating (dragees) or a varnish.
- compositions for oral administration there can be used pharmaceutically acceptable solutions, suspensions, emulsions, syrups and elixirs containing inert diluents such as water, ethanol, glycerol, vegetable oils or paraffin oil .
- inert diluents such as water, ethanol, glycerol, vegetable oils or paraffin oil .
- These compositions can include substances other than diluents, for example wetting, sweetening, thickening, flavoring or stabilizing products.
- the sterile compositions for parenteral administration can preferably be aqueous or non-aqueous solutions, suspensions or emulsions.
- solvent or vehicle water, propylene glycol, polyethylene glycol, vegetable oils, in particular olive oil, injectable organic esters, for example ethyl oleate or other organic solvents can be used. suitable.
- These compositions can also contain adjuvants, in particular wetting agents, isotonizers, emulsifiers, dispersants and stabilizers. Sterilization can be done in several ways, for example by aseptic filtration, by incorporating sterilizing agents into the composition, by irradiation or by heating. They can also be prepared in the form of sterile solid compositions which can be dissolved at the time of use in sterile water or any other sterile injectable medium.
- the doses depend on the desired effect, on the duration of the treatment and on the route of administration used; they are generally between 50 and 800 mg per day orally for an adult with unit doses ranging from 25 to 200 mg of active substance and between 25 and 600 mg per day intravenously for an adult with unit doses ranging from 12.5 to 200 mg of active substance.
- the doctor will determine the appropriate dosage based on age, weight and all other factors specific to the subject to be treated.
- Tablets containing 50 mg of active product having the following composition are prepared according to the usual technique:
- capsules containing 50 mg of active product having the following composition are prepared:
- a solution for injection containing 10 mg of active product having the following composition is prepared:
- the invention also relates to the process for the preparation of medicaments useful as radiorestorators, comprising mixing riluzole or the pharmaceutically acceptable salts of this compound with one or more compatible and pharmaceutically acceptable diluents and / or adjuvants.
- the invention also relates to a method of treating mammals and, in particular, humans requiring radioremediation comprising the administration of an effective amount of riluzole or the pharmaceutically acceptable salts of this compound.
