Definitions
- the present invention relates generally to laxatives.
- the present invention relates to a combination laxative which includes an osmotic laxa ⁇ tive and a bulk-forming laxative.
- the present invention relates to the granulated combinati ⁇ on of an osmotic laxative in the form of a sugar alcohol, such as lactitol, with a bulk forming laxative such as psyllium to provide a laxative form which is directly compressible.
- laxatives there are four general types of laxatives that are currently available: 1) bulk-forming; 2) osmotic; 3) sti- mulatory; 4) softening agents.
- the present application is directed toward the bulk-forming and osmotic types and specifically towards the use of an osmotic laxative in enhancing and correcting deficiencies found in bulk-for ⁇ ming laxatives. While bulk-forming laxatives such as those formed from psyllium husks provide generally safe and effective laxatives, psyllium laxatives generally suffer from three primary deficiencies. First, bulk-forming laxatives such as psyllium are not directly compressible and lack the ability to be readily formulated in tabletted form.
- psyllium seed husk has very poor wetting qualities and therefore does not mix well.
- the present invention addresses the poor compressi ⁇ bility of psyllium husk by combining the ground psyllium husk with a sugar alcohol, such as lactitol, which, as an osmotic laxative, has its own laxative properties.
- psyllium hydrophilic mucilloid has not yet successfully been provided in a tablet form but only in a powder form that may be dispersed in water.
- a chewable tablet containing psyllium would be beneficial because the masticating action in the mouth would aid dis ⁇ persion.
- the present invention combines psyllium, which is not directly compressible, with a sugar alcohol to form a compressible granulate which may be compressed into tab ⁇ lets.
- the present invention provides a solution to problems inherent with one laxative — bulk-forming laxa ⁇ tives such as psyllium seed husks — by combining the bulk-forming laxative with another laxative — an osmotic laxative, such as lactitol.
- psyllium hydrophilic mucilloid consists of the husk (eit ⁇ her milled or unmilled) of blond psyllium seeds.
- the psyllium hydrophilic mucilloid When ex- posed to water in the stomach and small intestine, the psyllium hydrophilic mucilloid forms a gelatinous mass which aids in the treatment of constipation by acting as a fecal softening agent and also acts to soothe and protect the small intestine.
- obtaining an appropriate gelatinous mass of psyllium hydrophilic mucilloid in the small intestine is problematic due to the poor dispersability and mixabi ⁇ lity of the psyllium hydrophilic mucilloid in water prior to in-reading.
- the individual particles of the psyllium hyd- rophilic mucilloid tend to lump or agglomerate together when mixed with water.
- the psyllium hydrophilic mucilloid often fails to evenly disperse throughout the gelatinous mass and the hydration of psyllium hydrophilic mucilloid tends to take place over the exterior surface of such an agglomerated mass to form gelatin-coated lumps, the inte ⁇ riors of which are substantially dry. These gelatin-coated lumps are less voluminous than properly dispersed psyllium hydrophilic mucilloid and therefore the laxative benefits of the psyllium are compro-mised.
- psyllium hydrophilic mucilloid The poor dispersability of psyllium hydrophilic mucilloid is exacerbated by its poor mixing characteris ⁇ tics. Psyllium hydrophilic mucilloid is difficult to wet and tends to float on the surface of water. When mixing with water is attempted, the psyllium hydrophilic mucil ⁇ loid forms lumps or masses. Psyllium is also difficult to mix when combined in the batter of a baked or continuously extruded food. Often, lumps of psyllium and material will result which result in an unacceptable food product due to textural deficiencies or to the poor taste of the psyllium material and psyllium derivatives.
- osmotic la ⁇ xatives act to retain water in the colonic lumen thereby counteracting the normal dehydrating action of the colon.
- the osmotic laxative produces a fecal stream which is softer, bulkier and easier to expel.
- Lactitol may be used as an osmotic laxative because it is not absorbed in the small intestine and is thereaf ⁇ ter hy-drolysed and fermented in the large bowel by the action of intestinal microflora resulting in th_e,_liberati- on of galactose and sorbitol which are thereafter metabo ⁇ lized to organic acids and short chain fatty acids by co- Ionic anaerobes.
- An osmotic effect is created in the co- Ion, which normally acts to hydrate the fecal stream.
- the reduction in the dehydrating action of the colon produces a softer, bulkier fecal stream.
- lactitol exhibits other properties which makes it a preferred candidate for combination with psyllium. Specifically, lactitol does not induce an inc ⁇ rease in blood glucose or insulin levels and contributes half the calo- ries of most other carbohydrates (2 calories per gram) . Because the control of blood glucose, lipids and body weight are primary goals in diabetes management, lactitol is considered to be a beneficial product for diabetics.
- Lactitol is also non- cariogenic and has a moderate, su- gar-like sweetness. Lactitol also has good solubility, low hygroscopicity, and when pro-vided in a crystalline form, is suitable for dry mixing. Finally, lactitol is also available at a price that is competitive with other sugar alcohols .
- the two types of laxatives discussed above, bulk-forming and osmotic operate by two entireJLy diffe ⁇ rent mechanisms. Bulk-forming laxatives absorb water and expand in the colonic lumen; in contrast, osmotic laxati ⁇ ves retain water in the colonic lumen by osmosis.
- manni ⁇ tol only as a low-calorie sweetener or substitute for free sugar, not as an osmotic laxative.
- Mannitol i is not pro ⁇ ven or recognized as a therapeutic osmotic laxative.
- Va ⁇ lentine also does not attempt to provide a psyllium laxa- tive in a tablet form.
- a laxative provided in tablet form could be desig ⁇ ned either for immediate swallowing or chewing.
- psyllium is not available in tablet form because it is simply not compressible. However, when combined with a sugar alcohol, such as lactitol, psyllium can be provided in a tablet form due to the sufficient compressibility of the psyllium/lactitol combination. The masticating action of the mouth aids in the dispersion of the psyllium.
- Pro ⁇ viding psyllium in a tablet form also provides a vehicle whereby other ingredients, such as medications, minerals and vitamins can be delivered with the laxative material. Finally, tablets are easily transported by the consumer and easily dispensed by the pharmacist.
- Hardness is a measure of a tablet's strength. Hardness is measured by determining the lateral breaking strength expressed in kilograms, Strong Cobb Units (S.C.U.) or Newtons (N) exerted on a single tablet at the moment of rupture. Typical hardness testers are manufactured by Key Instruments. In the context of chewa ⁇ ble tablets, the tablet hardness must be greater than about 30N to be commercially useful.
- Friability is another measure of a tablet's ability to resist chipping and breaking during shipment and handling. Friability is measured under stan ⁇ dard conditions by weighing out a certain number of tab ⁇ lets (generally 20 or more) and placing them in a rotating plexiglass drum in which they are lifted during replicate revolutions by a radial louver and then dropped through the diameter of the drum. The tablets are then re-weighed and a percentage of the powder that has rubbed off is cal ⁇ culated. Friability of less than about 10% is considered to be acceptable for most che-wable tablet contexts. It is therefore an object of the present invention to provide an improved laxative by combining a bulk-for ⁇ ming laxative with an osmotic laxative.
- Yet another object of the present invention is to provide an improved psyllium bulk-forming laxative by com ⁇ bining psyllium with an osmotic laxative.
- Another object of the present invention is to pro ⁇ vide an improved bulk-forming laxative/osmotic laxative combina-tion which may be provided in tablet form or pow- der form.
- the above and other objects are accomplished by the present invention in which it has been discovered that a combination of lactitol as an osmotic laxative and psyl ⁇ lium as a bulk-forming laxative.
- the combination of the present invention results in an improved laxative with the qualities of both an osmotic laxative and an enhanced bulk-forming laxative due to the enhanced compressibility, dispersability and mixability of the psyllium.
- One preferred embodiment involves the combination of psyllium hydrophilic mucilloid and lactitol.
- Specifi ⁇ cally approximately equal parts of psyllium hydrophilic mucilloid and lactitol are dry blended.
- the resulting pow ⁇ der mixture may be mixed with water and taken orally.
- a binder solution may be subsequently mixed with the psyllium and lactitol to produce a granulate.
- the gra ⁇ nulate may thereafter be dried and compressed into tab ⁇ lets.
- lactitol is lactitol monohydrate.
- Three known binder solutions are available, including 60% lactitol solution, 3% polyvinylpyrrolidone (PVP) solution and 10% gelatin (250 Bloom) solution. The addition of 10% by weight microcrystalline cellulose has been found to improve the hardness and friability of the tablets.
- PVP polyvinylpyrrolidone
- the resulting lactitol psyllium mixture is to be provided in a powder form, three known forms of lactitol are available. Specifically, the lactitol may be provided in the form of anhydrous lactitol crystals, lactitol mono ⁇ hydrate or anhydrous lactitol. It is preferred that the lactitol monohydrate and anhydrous lactitol monohydrate be milled to a maximum particle size of 125 microns or less.
- the preferred form of psyllium is Roeper (60 mesh) .
- the present invention may also be provided in the form of a baked product, such as a cookie, cracker or ca ⁇ ke.
- the present invention is provided in two forms: powdered and granulate.
- the granulate may either be dis- persed in water prior to ingestion or may be directly compressed into a tablet form.
- the preferred granulate form of the present invention includes a dry blend of ap ⁇ proximately equal parts of psyllium powder and lactitol. A liquid binder solution is then added and the psyllium, lactitol and binder solution is mixed and dried. The pre ⁇ paration is then compressed into tablet form.
- the follo ⁇ wing examples are provided.
- EXAMPLES 1-4 100 grams of lactitol monohydrate was dry-blended with 100 grams of psyllium powder.
- Example 1 The granulate of Example 1 was also combined with 10% by weight of microcrystalline cellulose (MCC) prior to tabletting. As seen below, the addition of MCC increased tablet hardness and decreased tablet friability.
- MCC microcrystalline cellulose
- Examples 3 and 4 include the same composition as that shown in Example 1, i.e., without the addition of microcrystalline cellulose. The following results were obtained:
- Softer tablets were obtained by using polyvinylpyr ⁇ rolidone (PVP) binder solution.
- PVP polyvinylpyr ⁇ rolidone
- Examples 5, 6 and 7 are presented below which illustrate the use of PVP binder solution.
- 100 g 51actitol was dry blended with 100 g psyllium powder.
- 29 g 3% PVP solution was added to the dry mixture and mixed until completely wetted.
- the mix was dried overnight at 60°C and sieved to obtain a suitable granulate.
- the granulate was blended with 1% magnesium stearate (w/w) and tabletted.
- Tablets can also be formed from the mixtures bound with a gelatin binder solution.
- a gelatin binder solution 100 g lactitol and 100 g psyllium powder were dry blended. 35 g 10% gelatin (250 Bloom) solution was slowly added to the mixture and mixed until thoroughly wetted. The mix was then spread out onto a metal tray and dried overnight at 60°C and sieved to produce a suitable granulate. The granulate was blended with 1% magnesium stearate (w/w) and tabletted.
- the weight, thickness and hardness properties are as follows:
- a lactitol solution was found to be the supe ⁇ rior binding solution and the addition of microcrystalline cellulose (MCC) was found to improve hardness and friabi ⁇ lity characteristics. If the product is to be provided to the consumer in powder form, the addition of a binder so ⁇ lution is not necessary.
- Examples 1-9 Either the granulate form (Examples 1-9) or the dry mixture (Examples 10-15) can be used to manufacture laxa ⁇ tive-containing baked goods.
- Two cookie recipes are as follows:
- Example 1 35.8% flour 18.3% shortening 17.5% eggs 10.4% skim milk powder 7.5% salt 0.2% baking soda 0.3% cream of tartar 0.2%
- the present invention may be provided in a powder form, a granulate form, a tablet form and in a ba ⁇ ked product. Additional components such as medications, vitamins and minerals may also be provided with the com ⁇ bination osmotic/bulk-forming laxative of the present in ⁇ vention. Intense sweeteners such as Acesulfame K and as ⁇ partame may be added to enhance the flavor of the pro ⁇ ducts. Flavorings and colors may also be used. Other tab ⁇ letting lubricants in addition to magnesium stearate will be apparent to those skilled in the art.
