Definitions

  • xylitol as an anti-chalk acting agent in compositions for oral use containing a calcium-containing compound as an active substance
  • the present invention relates to the use of xylitol as an anti-chalk acting agent in a nutriceutical and/or pharmaceutical composition for oral use containing a calcium- containing compound.
  • the composition is in the form of tablets that are designed so that they have an acceptable mouthfeel, whereby the tablets are chewable or suckable.
  • Calcium is essential for a number of key functions in the body, both as ionized calcium and a calcium complex.
  • a number of diseases, especially bone-related diseases, are treated/prophylactically treated by intake of a sufficient amount of a calcium-containing compound.
  • calcium Normally, calcium must be orally administered in a relatively high amount, which makes especially dosage forms like e.g. chewable or suckable tablets suitable.
  • one of the major problems in this respect is to obtain compositions that have a sufficient customer compliance in order to achieve a correct and efficient treatment. This problem is related to the unpleasant mouthfeel of calcium-containing compounds, which mouthfeel is very difficult to mask.
  • xylitol is able to circumvent the undesired mouthfeel of a calcium-containing compound.
  • this undesired mouthfeel is the chalky-like, gritty-like, dusty like and/or dry sensation normally characterized by e.g. calcium carbonate.
  • Xylitol is a normally used as an artificial sweetening agent and has as such been employed in various pharmaceutical compositions, but to the best of the inventor's knowledge it has not been recognized that xylitol possesses unique properties to counteract or circumvent the bad mouthfeel resulting from the intake of a calcium containing product.
  • the present inventor has found that the elimination or significant reduction of the bad mouthfeel of compositions containing a calcium-containing compound by use of xylitol has an outstanding effect both with respect to an initial effect, i.e. upon intake of the composition xylitol exerts its mouthfeel-masking effect, and with respect to an on-going effect, i.e. the effect lasts for a prolonged period of time (such as, e.g., for about 10 min or more after administration).
  • the present invention provides a novel use of xylitol as an anti-chalk acting agent.
  • anti-chalk means the characteristic mouthfell of e.g. calcium carbonate, which normally is regarded as chalky, dusty, gritty, dry and unpleasant.
  • the invention relates to the use of xylitol as an anti-chalk acting agent for the manufacture of compositions containing a calcium-containing compound as an active substance to counteract the chalky or unpleasant mouthfeel of the calcium- containing compound.
  • xylitol as an anti-chalk acting agent can be assed by testing whether a composition has an acceptable taste and mouthfeel when tested by a professional/skilled sensory test panel of at least 6 test persons.
  • a professional/skilled sensory test panel denotes test persons that have the ability or have been trained to have the ability of evaluating taste and mouthfeel of ingestible products. Suitable test are e.g. ISO- 6564, Sensory analysis - Methodology - Flavour profile methods and ISO- 5495 Sensory Analysis - Methodology - Paired comparison test.
  • xylitol should be used in a sufficient amount depending on the particular calcium-containing compound employed and the specific quality thereof. As demonstrated in the examples herein, the concentration of xylitol is at least about 10% w/w based on the total weight of the calcium-containing compound contained in the composition.
  • the concentration of xylitol is at least about 15% w/w such as, e.g., at least about 20% w/w, at least about 25% w/w, at least about 30% w/w, at least about 35% w/w or about 40% w/w or more based on the total weight of the calcium- containing compound contained in the composition.
  • Calcium-containing compound The use of xylitol according to the invention is especially relevant for a calcium- containing compound that is a physiologically tolerable calcium-containing compound and that is therapeutically and/or prophylactically active.
  • Calcium is essential for a number of key functions in the body, both as ionized calcium and a calcium complex (Campell AK.CIin Sci 1987; 72:1-10). Cell behaviour and growth are regulated by calcium. In association with troponin, calcium controls muscle contraction and relaxation (Ebashi S. Proc R Soc Lond 1980; 207:259-86).
  • Calcium selected channels are a universal feature of the cell membrane and the electrical activity of nerve tissue and the discharge of neurosecretory granules are a function of the balance between intracellular and extra cellular calcium levels (Burgoyne RD. Biochim Biophys Acta 1984;779:201-16). The secretion of hormones and the activity of key enzymes and proteins are dependent on calcium. Finally calcium as a calcium phosphate complex confers rigidity and strength on the skeleton (Boskey AL. Springer, 1988:171-26). Because bone contains over 99% of the total body calcium, skeletal calcium also serves as the major long-term calcium reservoir.
  • Calcium salts such as, e.g., calcium carbonate is used as a source of calcium especially for patients suffering from or at risk of osteoporosis. Moreover, calcium carbonate is used as an acid-neutralizing agent in antacid tablets.
  • osteopenia affects cancellous bone more than cortical bone and may not be completely reversible with calcium supplementation. If the animal is growing reduced calcium intake leads to stunting. In the premature human neonate the higher the calcium intake, the greater the increase in skeletal calcium accretion which, if high enough, can equal gestational calcium retention. During growth chronic calcium deficiency causes rickets. Calcium supplements in both pre- and postpubertal healthy children leads to increased bone mass. In adolescents the higher the calcium intake, the greater the calcium retention, with the highest retention occurring just after menarche.
  • Calcium salts like e.g. calcium carbonate is used in tablets and due to the high dose of calcium required, such tablets are often in the form of chewable tablets. It is a challenge to formulate e.g. chewable tablets containing a calcium salt, which tablets have a pleasant taste and an acceptable mouth feel without the characteristic dominating feeling of chalk.
  • a calcium-containing compound for use according to the invention may be e.g. bisglycino calcium, calcium acetate, calcium carbonate, calcium chloride, calcium citrate, calcium citrate malate, calcium cornate, calcium fluoride, calcium glubionate, calcium gluconate, calcium glycerophosphate, calcium hydrogen phosphate, calcium hydroxyapatite, calcium lactate, calcium lactobionate, calcium lactogluconate, calcium phosphate, dicalcium phosphate, calcium pidolate, calcium stearate, ⁇ -tricalcium phosphate and tricalcium phosphate.
  • Other calcium sources may be water-soluble calcium salts, or complexes like e.g.
  • Use of bone meal, dolomite and other unrefined calcium sources is discouraged because these sources may contain lead and other toxic contaminants. However, such sources may be relevant if they are purified to a desired degree.
  • the calcium-containing compound may be used alone or in combination with other calcium-containing compounds.
  • Of specific interest is bisglycino calcium, calcium acetate, calcium carbonate, calcium chloride, calcium citrate, calcium citrate malate, calcium cornate, calcium fluoride, calcium glubionate, calcium gluconate, calcium glycerophosphate, calcium hydrogen phosphate, calcium hydroxyapatite, calcium lactate, calcium lactobionate, calcium lactogluconate, calcium phosphate, calcium pidolate, calcium stearate and tricalcium phosphate.
  • Mixtures of different calcium-containing compounds may also be used.
  • calcium carbonate is especially suitable for use as a calcium-containing compound and calcium carbonate has a high content of calcium.
  • a calcium- and xylitol-containing tablet contains an amount of the calcium- containing compound corresponding to from about 100 to about 1000 mg Ca such as, e.g., from about 150 to about 800 mg, from about 200 to about 700 mg, from about 200 to about 600 mg or from about 200 to about 500 mg Ca.
  • Calcium carbonate can be in three different crystal structures: calcite, aragonite and vaterite. Mineralogically, these are specific mineral phases, which relate to the distinct arrangement of the calcium, carbon and oxygen atoms in the crystal structure. These distinct phases influence the shape and symmetry of the crystal forms.
  • calcite is available in four different shapes: scalenohedral, prismatic, spherical and rhombohedral, and aragonit crystals can be obtained as e.g. discrete or clustered needle-like shapes. Other shapes are also available such as, e.g., cubic shapes (Scoralite 1A + B from Scora).

  • vitamin D In addition to its action on calcium and skeletal homeostasis, vitamin D is involved in the regulation of several major systems in the body.
  • the actions of vitamin D are medicated at the genome by a complex formed by 1 ,25-(OH) 2 vitamin D mainly produced in the kidney, with the vitamin D receptor (VDR).
  • VDR vitamin D receptor
  • the 1 ,25-(OH) 2 vitamin D/VDR complex has important regulatory roles in cell differentiation and in the immune system. Some of these actions are probably dependant on the ability of certain tissues other than the kidney to produce 1 ,25-(OH) 2 vitamin D locally and act as a paracrine (Adams JS et al. Endocrinology 1996; 137:4514-7).
  • Vitamin D insufficiency the preclinical phase of vitamin D deficiency, also causes a reduced calcium supply and secondary hyperparathyroidism, albeit of a milder degree than found with deficiency. If this state remains chronic, osteopenia results.
  • the biochemical process underlying this state of calcium insufficiency is probably inappropriate level of 1 ,25-(OH) 2 vitamin D due to a reduction in its substrate 25-OHD (Francis RM et al. Eur J Clin Invest 1983; 13:391-6).
  • the state of vitamin D insufficiency is most commonly found in the elderly. With age there is a decrease in serum 25-OH vitamin D due to decreased sunlight exposure and possible to decreased skin synthesis.
