Abstract
ABSTRACT OF THE DISCLOSURE
An appetite curbing preparation comprising an alginate and diphosphonic acid or a nontoxic pharma-cologically acceptable water-soluble salt thereof as an inhibitor of the precipitation of calcium salts. This preparation is useful for curbing the appetite of a warm-blooded animal.
An appetite curbing preparation comprising an alginate and diphosphonic acid or a nontoxic pharma-cologically acceptable water-soluble salt thereof as an inhibitor of the precipitation of calcium salts. This preparation is useful for curbing the appetite of a warm-blooded animal.
Description
1(~4101~
The present invention relates to appetite curbing compositions for mammals, methods for the preparation of such compositions, and methods for curbing the appetite of mammals by use of said compositions.
It is known to produce preparations based on alignates for use as appetite curbing agents in slimming diets. Since these preparations swell in the stomach and ~ `
intestinal tract, they produce a feeling of fullness and satisfaction in human beings. However, the preparations 10 have a considerable disadvantage in that in the presence of calcium ions they form calcium-containing deposits of low solubility. As a result, it is possible for a calcium ion deficiency to be produced, particularly in the intestinal tract. The fear has therefore often been voiced that dis-turbances of the metabolism could thereby be produced.
It is an object of the present invention to over-come the above-described drawbacks of the prior art.
It is another object of the present invention to proyide A preparation comprising alginic acid and a diphosphonic 20 acid ~or nontoxic pharmacologically acceptable water-soluble salts thereof~ in which the diphosphonic- acid acts as inhibitor of the precipitation of calcium salts; and thereby inhibits precipitation of calcium ions; this preparation is useful for curbing the appetite of a warm-blooded animal.
These and further objects of the present invention -~
will become apparent as the description thereof proceeds.
The present invention relates to alginic acid pre-parations containing a diphosphonic acid (or nontoxic pharma-cologically acceptable water-soluble salts thereof) as inhibitor 30 of the precipitation of calcium salts when the composition is ingested. This preparation is useful as an appetite curbing agent for warm-blooded animals.
cb/ - 1 -1(~410~3 Accordingly, the present invention provides a pre-paration for use in curbing the appetite of warm-blooded animals which comprises an alginic compound and a diphosphonic compound of the formula:
wherein Rl is hydrogen or methyl and the nontoxic pharma-cologically acceptable water-soluble salts thereof, as inhibitor of the precipitation of calcium salts when the composition is administered to warm-blooded animals.
More particularly, the present invention is directed to an appetite curbing preparation for warm-blooded animals comprising (A) an alginic compound selected from the groups consisting of alginic acid and the nontoxic pharmacologically acceptable water-soluble salts thereof, and ~ 3) a substoichiometric amount based on the calcium ions required to gel said ~lginic compound of a diphosphonic compound as precipitation inhibitor for calcium ions selected ; from the group consisting of a diphosphonic compound having the formula CH2 ~ IH ~ I R
wherein Rl is hydrogen or methyl and the nontoxic pharma-cologically acceptable water-soluble salts thereof.
Also, the present invention provides an appetite curbing composition for a warm-blooded animal consisting essen-tially of 25% to 50% by weight of the above appetite curbingpreparation and 50~ to 75% by weight of a nontoxic pharma-~ologically acceptable carrier.
,,,, ~
~- cb/ - 2 -In addition, the present invention provides a method for curbing the appetite of warm-blooded animals comprising ~ :
administering to said animals an anoretically effective amount of the appetite curbing preparation mentioned above.
Also, the present invention provides an improvement in a process for dieting, which consists essentially in con-suming ~during or before a meal) an effective amount of the appetite curbing preparation mentioned above as an anoretic material.
It has become apparent that in principle it is possible to preyent the formation of calcium alginate by add-ing thereto a strong sequestering agent, for example, nitrilo-triacetic acid or ethylenediaminetetraacetic acid. However, the calcium ions are thereby sequestered to such an extent that they may possibly no longer be available for physiological processes in the warm-blooded animal. Moreover, the precipi-tation of the calcium salts can be prevented for a consider-able period of time by using compounds which have a strong -~
inhibiting effect (threshold effect). In this case, crystalline growth is probably inhibited to a very great extent by the incorporation of the inhibitor into seed crystals. Compounds haying a threshold effect particularly include polyphosphates haying a chain-like structure and include sequestering agent phosphonic acids, such as methylphosphonosuccinic acid or 2-phosphonobutane~l,2,4-tricarboxylic acid. However, condensed phosphates are not suitable for this purpose since they are split up by phosphatases in the body to give ineffective monophosphate. Moreover, tests have shown that, under the physiological conditions which prevail in the intestinal tract, the majority of sequestering agent phosphonic acids are either unsuitable or are not sufficiently effective.
It was therefore surprising that the above-cb/ h 3 _ ., , mentioned dicarboxydiphosphonic acids and their nontoxicpharmacologically acceptable water-soluble salts constitute suitable ingredients for the above preparation. The com-pounds are diphosphonoalkanedicarboxylic acids selected from the group consisting of l,l-diphosphonopropane-2,3-dlcarboxylic acid and 2,2-diphosphonobutane-3,4-dicarboxylic acid, with the former acid being preferred.
Instead of these acids, it is also possible to use their nontoxic pharmacologically acceptable, water-soluble salts, such as the alkali metal salts, for example, sodium and potassium, and the magnesium salts, and the ammonium and substituted ammonium salts such as the lower alkylol-ammonium salts, for example, the mono-, di- or tri- ethylolammonium salts. It is also possible to use the partial salts, in which only a proportion of the acidic protons is replaced by other cations. Partial salts, which produce a pH in the range ~om 6 to 8.5 in aqueous solution, are preferred. Mixtures of the above-mentioned acids and their salts can also be used.
The proportion of the precipitation inhibitors in the appetite curbing preparations containing an alginic com-pound is variable. However, this proportion must be great enough to inhibit the precipitation of calcium ions in the intestinal tract. This precipitation is possibly caused by the presence of calcium hardness (i.e., calcium ions) in the wate~. Based upon a 10 gm amount of the alginic compound, about 50 to 200 mg,preferably 100 to 200 mg, of the precipi-tation inhibitor can be present in compositions of the invention.
This corresp~nds to the weight ratio of l50 to 200):1 for the alginic compound to the precipitation inhibitor, equivalent to 1/2% to 2% of the inhibitor on the weight of the alginic compound. However, for the ressons as stated above, precipi-tation inhibitor is preferably present in substoichiometric cb/ ~ - 4 _ - lV~1013 amount based on the calcium required to gel said alginic compound.
Commercial alginic acid, or its nontoxic pharma-cologically acceptable water-soluble salts such as the alkali-metal salts, are suitable as the alginic ingredient. Potassium alginate or, preferably, sodium alginate can be used as alkali metal salts. Ammonium alginate can also be used. The pre-parations can be produced for administration in the form of tablets, pills or powder and may contain known ingredients such as sodium bicarbonate or Na2HPO4 as well as binding agents for the production of tablets. Further additives which may be present in the appetite curbing compositions are flavorings, vitamins and sugar/fruit concentrates.
Generally speaking, the appetite curbing composi-tions according to the invention contain from 25% to 50% by weight of the alginate-diphosphonic acid preparation, with the balance up to 100% by weight being the other known ingred-ients and/or additives mentioned aboye which constitute an inert nontoxic pharmacologically acceptable carrier.
The appetite curbing compositions are administered orally to warm-bloQded animals in units which contain an anoretically effective amount, or about 15 to 70 mg/kg of body weight ~preferably 25 to 50 mg/kg of body weight~, of the alginic-diphosphonic acid combination. These dosage units can be in the form of tablets, pills or powders and are con-veniently administered by dissolving the tablets, pills or powders of the combination in a suitable liquid medium such as water, milk, fruit juice or a carbonated beverage. The liquid medium contains from 0.5% to 5% by weight of the appetite ' 30 curbing composition, and can be consumed by drinking.
The appetite curbing preparations of the present invention have the advantage of preventing precipitation "

or excessive sequestering of calcium ions. The ease of digest-ibility of the anoretic agent is greatly increased, even for sensitive persons.
The following examples illustrate the present invention without limiting it in any manner.
EXAMPLE
In order to test the activity of the compositions containing compounds which might be effective as precipitation inhibitors, the following experiments were carried out. 600 mg of sodium alginate was slowly stirred into 50 ml of a solution of sodium bicarbonate ~Na2HPO4) containing the inhibitor stated in Table I. After filling up to the final volume, the follow-ing concentrations were obtained per liter of alginate solution:
6 gm of sodium alginate 0.075 gm of precipitation inhibitor ; 2 gm of HC03 ions 0.1 gm of HPO4 ions The above concentrations of bicarbonate and hydrogen phosphate ions were approximately equivalent to the inorganic components of intestinal juice. The solution had a pH of 8.
As soon as the sodium alginate had homogeneously dissolved, - 50 ml of 40 dH ~German hardness) hard water was added, so that the sQlution had a calcium hardness of 20 dH. The : precipitatlon of calcium alginate became apparent through ~elling or clotting, whlch could readily be observed by means of deposlts on the walls of the container when the sample was shaken.
A control sample of the alginic compound was also mixed with the bicarbonate-hydrogen phosphate solution. The ; 30 results of the control test together with the results of the test with a composition of the inyention are reported in Table I. The results of the same tests with comparative ' ~h - cb/ - 6 -: ' ;: ' .:
