The present invention relates to a combination of a monoamine neurotransmitter re-uptake inhibitor and an acetylcholinesterase inhibitor, and the use of the combination in treating neurodegenerative conditions such as Alzheimer's Disease.
2. BACKGROUND INFORMATION
Alzheimer's Disease is an insufficiently understood neurodegenerative condition mainly affecting the elderly but also younger people who are mainly genetically pre-dispositioned to it.
One postulated method of treatment comprises the administration of acetylcholinesterase inhibitors which act on the cholinergic system.
However, this method suffers from the disadvantages that these compounds induce a range of side-effects, especially gastro intestinal discomfort including nausea , diarrhoea and salivation.
The tropane derivative having dopamine reuptake inhibitor activity for use according to the invention may in particular be tropane derivatives such as those disclosed by patent applications EP 604355, EP 604352, US 5444070, EP 604354, WO 95/28401, and WO 97/30997.
However, there is no hint to combine these compounds with an acetylcholinesterase inhibitor. The present invention provides a new and surprisingly effective combination of an acetylcholinesterase inhibitor and for separate, sequential or simultaneous administration of any monoamine neurotransmitter re-uptake inhibitors.
Surprisingly the combination provides i) lower doses to be used as expected for the single drugs, and ii) a reduction or minimization of the adverse event profile of each single drug which increases general tolerability and compliance of both substances and decrease any adverse side effects as the profile of each substance is totally different due to the different mechanism of action.
BRIEF SUMMARY OF THE INVENTION
Accordingly, the invention relates to a pharmaceutical composition comprising a monoamine neurotransmitter re-uptake inhibitor comprising a 2,3-disubstituted tropane moiety, or a tautomer, a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof Q j and at least one acetylcholinesterase inhibitor or a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (2), and a pharmaceutically acceptable carrier or excipient, and optionally one or more other therapeutic ingredients.
The present invention provides a greater than expected improvement in the condition of subjects suffering from a neurodegenerative disorder with an associated cognitive deficit, such as Alzheimer's Disease, Lewis body disease, fronto-temporal dementia, or from a cognitive deficit which may arise from a normal process such as aging like cerebrovascular dementia and milder forms as age associated memory impairment (AAMI) or mild cognitive impairment (MCI) or from an abnormal process such as injury, than would be expected from administration of the active ingredients alone. Further, the combination allows for a lower overall dose of each of the active ingredients to be administered thus reducing side effects and decreasing any reduction in the effectiveness of each of the active ingredients over time.
There is also provided a kit of parts comprising at least two separate unit dosage forms (A) and (B): (A) one of which comprises a composition a monoamine neurotransmitter re-uptake inhibitor comprising a 2,3-disubstituted tropane moiety, or a tautomer, a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (1), and optionally a pharmaceutically acceptable carrier; (B) one of which comprises a composition containing one or more acetylcholinesterase inhibitors or a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (2), and optionally a pharmaceutically acceptable carrier, for simultaneous, sequential or separate administration.
There is also provided the use of a combination of a monoamine neurotransmitter reuptake inhibitor comprising a 2,3-disubstituted tropane moiety, or a tautomer, a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (1) and at least one acetylcholinesterase inhibitor or a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (2) in a combined form, or separately or separately and sequentially, wherein the sequential administration is close in time or remote in time, for the manufacture of a medicamentation for the prevention or treatment of a disease or a disorder, which is responsive to the inhibition of monoamine neurotransmitter re-uptake and or to AChE inhibition.
There is also disclosed a method of prevention or treatment of a disease or disorder, which disease or disorder is responsive to the inhibition of monoamine neurotransmitter reuptake, which method comprises administration of effective amounts of a monoamine neurotransmitter re-uptake inhibitor comprising a 2,3-disubstituted tropane moiety, or a tautomer, a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (1) and at least one acetylcholinesterase inhibitor or a pharmaceutically acceptable salt, solvate, or physiologically functional derivative thereof (2) to a patient in need thereof in a combined form, or separately or separately and sequentially wherein the sequential administration is close in time or remote in time.

The pharmaceutical compositions of the present invention are suitable for oral, intravenous, intravascular, intraperitoneal, subcutaneous, intramuscular, inhalativ, topical, patch or suppository administration.
The pharmaceutical compositions of the present invention are preferably in unit dosage forms such as tablets, pills, capsules, powders, granules, sterile parenteral solutions or suspensions, metered aerosol or liquid sprays, drops, ampoules, transdermal patches, auto- injector devices or suppositories; for oral, parenteral, intranasal, sublingual or rectal administration, or for administration by inhalation or insufflation. For preparing solid compositions such as tablets, the principal active ingredient is mixed with a pharmaceutical carrier, e. g. conventional tableting ingredients such as corn starch, cellulose, carboxymethylcellulose, hydroxypropylmethylcellulose, lactose, sucrose, sorbitol, talc, silicon dioxide, polyethylene glycol, stearic acid, magnesium stearate and dicalcium phosphate or gums or surfactants such as sorbitan monooleate, polyethylene glycol, and other pharmaceutical diluents, e. g. water, to form a solid pre-formulation composition containing a homogeneous mixture of a compound of the present invention, or a pharmaceutically acceptable salt thereof. When referring to these pre-formulation compositions as homogeneous, it is meant that the active ingredient is dispersed evenly throughout the composition so that the composition may be readily subdivided into equally effective unit dosage forms such as tablets, pills and capsules.
This solid pre-formulation composition is then subdivided into unit dosage forms of the type described above containing from 0.05 to 10,000 mg, in particular 0.1 to about 500 mg, most preferably 0.1 to 250 mg of each active ingredient of the present invention. Typical unit dosage forms contain from 0.1 to 100 mg, for example 0.1, 0.5, 1, 2, 5, 10, 25, 50 or 100 mg, of each active ingredient. The tablets or pills of the novel composition can be coated or otherwise compounded to provide a dosage form affording the advantage of prolonged action. For example, the tablet or pill can comprise an inner dosage and an outer dosage component, the latter being in the form of an envelope over the former. The two components can be separated by an enteric layer which serves to resist disintegration in the stomach and permits the inner component to pass intact into the duodenum or to be delayed in release. A variety of materials can be used for such enteric layers or coatings, such materials including a number of polymeric acids and mixtures of polymeric acids with such materials as shellac, cetyl alcohol and cellulose acetate.
Similarly, cachets and lozenges are included. Tablets, powders, capsules, pills, cachets, and lozenges can be used as solid forms suitable for oral administration.
The liquid forms in which the novel compositions of the present invention may be incorporated for administration orally or by injection include aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, and flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil, as well as elixirs and similar pharmaceutical vehicles. Suitable dispersing or suspending agents for aqueous suspensions include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone or gelatin.
For preparing suppositories, a low melting was, such as admixture of fatty acid glycerides or cocoa butter, is first melted and the active component is dispersed homogeneously therein, as by stirring. The molten homogenous mixture is then poured into convenient sized molds, allowed to cool, and thereby to solidify.
Formulations suitable for vaginal administration may be presented as pessaries, tampons, creams, gels, pastes, foams or sprays containing in addition to the active ingredient such carriers as are known in the art to be appropriate.
Administration to the respiratory tract may also be achieved by means of an aerosol formulation in which the active ingredient is provided in a pressurised pack with a suitable propellant such as a chlorofluorocarbon (CFC) or fluorohydrocarbon (HFC) for example dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, 1,1,1,2- tetrafluoroethan (HFC-134(a) ), or 1,1,1,2,3,3,3-heptafluoroprpane, carbon dioxide, or other suitable gas. The aerosol may conveniently also contain a surfactant such as lecithin and/or a co-solvent such as ethanol. The dose of drug may be controlled by provision of a metered valve.
Alternatively the active ingredients may be provided in the form of a dry powder, for example a powder mix of the compound in a suitable powder base such as lactose, starch, starch derivatives such as hydroxypropylmethyl cellulose and polyvinylpyrrolidone (PVP). Conveniently the powder carrier will form a gel in the nasal cavity. The powder composition may be presented in unit dose form for example in capsules or cartridges of, e.g., gelatin, or blister packs from which the powder may be administered by means of an inhaler. In formulations intended for administration to the respiratory tract, including intranasal formulations, the compound will generally have a small particle size for example of the order of 5 microns or less. Such a particle size may be obtained by means known in the art, for example by micronization.
