Abstract

Abstract Nutritional supplement There are provided lithium-containing nutritional supplements, e.g. foodstuffs, multi-vitamin/mineral preparations and parenteral and enteral alimentation solutions containing physiologically tolerable lithium compounds.

Description

l- 13323~8 ~

NUTRITIONAL SUPPLE~ENT

The present invention relates to the use of physiologically tolerable lithium compounds and in particular to the use of such compounds for the manufacture of nutritional supplements for use in combatting conditions associated with essential chemical deficiency.
Lithium compounds have been widely used in ` the treatment of manic depressive psychosis but have also been reported as being suitable for the treatment of other ailments. Thus Sherwin in US-A-363962S suggests the use of topical lithium succinate compositions for the treatment of various skin - ~ diseases, Horrobin and Lieb in US-A-4386072 suggest the use of lithium compounds for the treatment of certain disorders of inflammation and immunity, EP-B-85579 tEfamol Ltd.~ suggests the use of lithium compounds for the treatment of skin lesions, and EP-A-132126 (Efamol Ltd.) suggests the use of topical lithium-containing compositions in the treatment ` ~ of seborrheic dermatitis, a fungal disease arising from excessive multiplication of a fungus which is normally present on the skin surface at tolerable levels.
Lithium treatment however has often been acaompanied by a number of side-effects which are generally related to dosage levels and to the degree of accumulation. Particular side-effects which ;~ have occurred, especially in the treatment of manic depressive illness, include transient nausea, fine tremor, fatigue, muscular weakness, polydipsia ~ and polyuria. Thus it is stated in Martindale = The Extra Pharmacopoeia 28th Edition (1982) 1538 `-~ that the margin between the therapeutic and the ~ toxic concentration of lithium is narrow, and that , .

;
.~
- 2 - 13323~8 therefore it should be given under close medical supervision.
We have now surprisingly fo~nd that significantly depressed lithium plasma levels, relative to those of healthy sub~ects, are associated with a number of ailments and diseases, in other words that lithium appears to be an essential trace element.
Thus in healthy sub~ects lithium plasma levels may generally be in excess of 0.04 mM/l, whereas in sub~ects suffering from atopic eczema or seborrheic dermatitis mean plasma levels of below 0.025 mM/l are found. Alcoholics, patients with psoriasis, candidiasis, pityriasis and other fungal skin infections and sufferers from combination skin similarly exhibit depressed lithium plasma levels. lCombination skin is a troublesome and unsightly complaint manifested `; by excessive greasiness in certain skin areas, such as the forehead and the nose, and excessive dryness in other skin areas, such as the sides of the face).
We now propose therefore that conditions associated with essential chemical deficiency due to low lithium plasma levels may be countered or prevented from arising by the administration of a nutritional supplement containing a physiologically tolerable lithium compound.
~ ~ Viewed from one aspect, the present invention ;~; thus provides the use of a physiologically tolerable I ~ lithium compound for the manufacture of a nutritional supplement for use in combatting conditions associated with essential mineral deficiency, more particularly lithium deficiency.
The nutritional supplement, which conveniently may be sterile, may be in a form adapted for enteral, parenteral or topical administration, but most preferably will be in a form adapted for oral ingestion ~-~ or parenteral, e.g. iv, injection or infusion.
Liguid preparations made with sterile or deionized '~, `':

., , 13323~8 water are particularly preferred. However, in another preferred embodiment the nutritional supplement may take the form of dietary supplement, such as a foodstuff. The nutritional supplement may alterna-tively be in a conventional pharmaceutical dosage form adapted for administration to the gastrointestinal tract. In this regard, forms such as tablets, coated tablets, capsules, powders, drops, suspensions, solutions, syrups and suppositories deserve particular mention. Nevertheless as lithium nutritional supplemen-tation may be achieved by parenteral or topical administration, for example by injection or by topical application (e.g. of an ointment, lotion, cream, paæte or gel or the like), or by transdermal iontophoretic delivery, the nutritional supplement may be in the form of a composition adapted for one of these administration modes.
Where the nutritional supplement is prepared in a conventional pharmaceutical dosage form it may of course also contain conventional pharmaceutical carriers or excipients.
For parenteral administration by injection - or infusion the nutritional supplements of the invention are preferably formulated as sterile solutions, emulsions or suspensions, e.g. in water for injections or in solutions in a lipid or l~pid solvent, e.g. the alcohol analogues of the polyunsaturated fatty acids discussed below.
` For oral administration, the nutritional supplement may conveniently take the form of a foodstuff, for example a food or drink mix, into which a lithium compound is incorporated. The lithium containing nutritional supplement of the ~ invention may particularly suitably be in the form ; ~ of a so-called "complete" foodstuff, analogous to those which are prepared to serve as the major ; or sole source of nutrition for example for people ~ , ",~ " ,"~ ` :

;

-- 13~23~8 wishing to loose weight, for post-operative patients, for elderly patients, for convalescents, or for individuals with ~pecific dietary needs (e.g. patients with diabetes, coeliac disease or cystic fibrosis~.
For most people however a lithium supplemented foodstuff will preferably be of a type that is ingested daily in similar quantities, and for this reason the supplement will particularly conveniently comprise the lithium compound and a cereal or legume foodstuffs base. In an especially Preferred embodiment, the nutritional supplement may be in the form of a breakfast cereal. In a preferred alternative, however; the nutritional supplement may take the form of a lithium-containing multi-vitamin/multi-mineral preparation, for example in tbe form of tablets, capsules, or drops. In this regard, composi-tions are especially preferred which-contain the lithium compound together with sources of one, some or all of the vitamins and the other essential elements, for example selected from vitamins A, Bl, B2, B3, B6, B12, C, D and E ana calcium, copper, zinc, manganese and iron. In another embodiment, the lithium compound may be incorporated into an enteral or parenteral alimentation solution. The nutritional supplement of the invention may however contain the lithium compound as the sole active ingredient.
For topical administration, the nutritional supplement will again preferably be in a form adapted for regular application in subs~antially similar quantities and thus the lithium compound may particularly conveniently be incorporated within cosmetics, `''f~ such as facial creams and ointments and the like.
`~ The lithium compound used according to the invention may be any physiologically tolerable lithium compound that permits lithium uptake by the body. In general therefore, the preferred ~ compounds will be lithium salts and in particular ,'.' ~

133~3~8 those salts which are at least sparingly water-soluble. Particularly suitable lithium compounds thus include lithium carbonate, lithium citrate, lithium chloride, lithium succinate, lithium sulphate, lithium salicylate, lithium acetylsalicylate, lithium orotate and the lithium salts of polyunsaturated fatty acids, especiallY the C18_22 fatty and more especially the essential fatty acids.
Thus it is especially preferred that the nutritional supplement contain at least one lithium salt of an essential fatty acid in the n-6 series (e.g.
18:2 n-6 ~linoleic acid), 18:3 n-6 (gammalinolenic acid), 20:3 n-6 (dihomogammalinolenic acid), 20:4 n-6 (arachidonic acid), 22:4 n-6 (adrenic acid) and 22:5 n-6) or in the n-3 series (e.g. 18:3 n-3 (alpha linolenic acid), 18:4 n-3, 20:4 n-3, 20:5 n-3 (eicosa-pentaenoic acid), 22:5 n-3 and 22:6 n-3 (docosahexa-enoic acid)).
Most especially preferably the nutritional supplement will contain at least one essential fatty acid of the n-3 series, or a salt, most preferably the lithium salt thereof, and at least one essential fatty acid of the n-6 series, or a salt, again -~ most preferably the lithium salt, thereof.
;~ ~he essential fatty acids are essential nutrients which must be provided in the diet because they cannot be manufactured by the body. The main dietary essential~fatty acids are linoleic and alphalinolenic acids but to be fully utilised the essential fatty acids must be metabolised along the n-3 or n-6 pathways, of which alphalinolenic and linoleic acids are the respective starting points.
In patients who are receiving no food or only insufficient food by the normal oral route the essential fatty acids must be provided by enteral or parenteral feeding.
On enteral adminstration, however,the fatty materials may not be fully absorbed by patients , '~ -,~ . .
:

~ 13323~8 having fat malabsorbtion. Such malabsorbtion is particularly likely to occur with patients with defective pancreatic or hepatic functions, with certain intestinal diseases or with cystic fibrosis.
Essential fatty acids thus may be administered intravenously as parenteral nutrition suPplements but at present this is generally done by administration of liquid emulsions, usually containing linoleic acid with or without alphalinolenic acid. Such liquid emulsions are not readily compatible with conventional aqueous fluids for parenteral nutrition, administration of liquid emulsions is not clear of side effects and there is particular concern regarding possible effects on the lungs, especially of infants.
We have found that the lithium salts of the essential fatty acids surprisingly are crystalline solids at ambient temperature which are highly soluble in water and alcohol. These properties facilitate preparation of compositions containing lithium or the essential fatty acids and thus the salts can be used to promote lithium and/or essential fatty acid uptake following administration. Where essential fatty acids are to be incorporated into the nutritional supplements of the invention they may accordingly be particularly conveniently incor-porated as the lithium salts. However the essential fatty acids may also conveniently be incorporated in the form of salts with other counterions, especially the sodium and potassium salts which are also water soluble. Particularly conveniently, the nutritional supplement may contain two or more essential fatty acid sodiumr lithium or potassium salts.
Where the nutritional supplements are for parenteral administration and contain essential fatty acid salts they are preferably formulated as aqueous solutionsr and preferably are stored under an inert atmosphere, e.g. in nitrogen flushed vials, buffered to a pH in the range 8.5 to 9.0, e.g.
,~

., ~;.'' .

~ 1332358 with a physiologically acceptable acid such as citric acid. Moreover, such solutions preferably contain an antioxidant, e.g. a fatty acid derivative of ascorbic acid such as ascorbyl palmitate, a tocopherol ~e.g. gamma tocopherol or a mixed tocopherol~
or butylated hydroxy toluene.
The essential fatty acid supply required to prevent essential fatty acid deficiency is probably within the range 0.5-8% of total daily calorie intake, especially 1-3% (or 1-5~ during periods of metabolic stress such as rapid growth, pregnancy, lactation or injury~. In the case of orally or parenterally administrable nutritional supplements, the nutritional supplements are preferably administered at a daily or one-off dosage of the essential fatty acid or salt thereof of 1 to 100,000 mg, especially 1-50000 mg, preferably 100-10000 mg, conveniently ~` in dosage units of 50, 100, 250, 500 or 1000 mg.
For topical administration, concentrations of the essential fatty acids or salts thereof may conveniently be 0.001 to 50%, for example from 0.01 to 30%, preferably 0.1 to 5%, by weight.
Where the nutritional supplement of the invention contains a lithium salt of a polyunsaturated fatty acid and is in a form adapted for oral administration, the~litbium salt in the supplement is preferably ~ -provided with a ~astric juice resistant release rk~ ;delaying coating, e.g. a Eudragit coating as supplied by~ROhm GmbE of Darmstadt.
The lithium content in the nutritional supplement will be selected according to the nature of the ~-~ supplement and its administration route but in qeneral will be within the range 1 ppb to 30% by weight of lithium, preferably 1 ppm to 20% lithium, especially preferably 0.001 to 10% lithium and particularly preferably up to 1% lithium. Obvlously, where the nutritional supplement is in the form of a complete foodstuff, the lithium content will ~ Ae~

~\

be towards the lower ends of the ranges specified above, for example it may conveniently be in the range 1 ppb to 10 ppm, preferably 10 ppb to 1 ppm.
Thus, for example in complete foods which might be administered in a dose of 500g/day, a lithium content of 5mg might be contemplated. More particularly, the daily dosage will generally be such that the adult body receives from 1 microgram to 50 mg, preferably 1 to 10 mg,-of lithium per day, and it will preferably be such as to maintain the lithium plasma level above 0.04 mM/l.
Viewed from a further aspect, the invention thus provides a nutritional supplement comprising a foodstuffs base with included therein a physiologi-cally tolerable lithium compound in a concentration such that said supplement contains from 1 ppb to 1% by weight of lithium. Nutritional supplements prepared from sterilized or deionized base materials would be particularly preferred.
Viewed from a yet further aspect, the invent~on also provides a nutritional supplement comprising a sterile composition containing a physiologically tolerable lithium compound together with four or more, preferably eight or more, vitamins or minerals, for example essential vitamins or minerals selected from the group consisting of vitamins A, Bl, B2, B3, B6, B12, C, D and E and physiologically tolerable calcium, copper, zinc, manganese and iron compounds, and optionally together with at least one physiologi-cally acceptable carrier or excipient~
l ~; , Viewed from a still further aspect, the invention also provides a nutritional supplement comprising a parenteral or enteral alimentation solution containing ~ a physiologically tolerable lithium compound.
