Description

A COMPOSITION FOR REDUCING FAT ABSORPTION
This invention relates to a composition for reducing the absorption of fats from the gastrointestinal tract.
Background of the invention
The incidence of obesity has increased dramatically over the past few decades in most developed countries and one reason for this has been a very large increase in the amount of fat consumed by the average member of the public. A great many solutions to this problem have been proposed ranging from special diets and exercise regimes, lipid-reducing food supplements and diet-suppressing drugs to surgical interventions such as gastric bands.
Various natural, semi-synthetic and synthetic substances have been developed and used for the purpose of binding lipids in the gastrointestinal (01) tract in order to reduce or prevent absorption of the lipids. For example, synthetic polymer resins which may be polyamines or anionic polymeric resins have been proposed and used for binding to bile acids thereby preventing their reuptake and use in the biosynthesis of cholesterol. Examples of substances of this type are disclosed in GB929391 (Merck). A problem with bile acid sequestering resins has been their lack of palatability. Consequently, much research has been expended in finding combinations of the resins with agents that improve the palatability of the resins.
For example, US560 1837 discloses combinations of psyllium husk and cholestyramine for treating hypercholesterolemia. US5286481 discloses combinations of an anion-exchange resin such as cholestyramine, colestipol or polidexide and bran for use in weight-reduction.
Other examples of substances for use in binding bile acids or other lipids such as triglycerides are disclosed in DE4136325 (Hoechst), which discloses cyclodextrins as bile acid adsorption agents useful for treating hyperlipidaemia, and US200410126444 (Dallas etaL), which discloses the use of powdered plant material from the cladodes of cacti for binding dietary fats.
Chitosan has been used for binding and preventing the absorption of dietary fats.
Chitosan is a deacetylated form of chitin, an amino polysaccharide (poly-N-acetyl glucosamine) found in the exoskeleton of arthropods (e.g., crustaceans such as lobsters and crabs) and also found in some plants and fungi. Chitosan is similar in structure and properties to dietary fibre (e.g., vegetable bran, cellulose) but, unlike like bran and cellulose, chitosan has the ability to bind fat and other lipids in the intestine. A known problem with chitosan, as disclosed in W099/21 566 (Rexall Sundown), is that when chitosan is consumed in the quantities required for dietary fat reduction, constipation can result. Indeed, W09912 1566 discloses that the use of chitosan as a dietary supplement must be of short duration or other ingredients or supplements added to combat the undesirable effects of the chitosan.
W099/21566 proposes the addition of aloin, which contains aloe saponins, in order to offset the constipating effect of chitosan. U54999341 discloses the use of soy sapon ins to offset the constipating effect of the chitosan. U52007/0048392 (Oben) discloses the use of combinations of chitosan and a plant extract from a plant of the Cissus, Vernonia or Brillantasia families.
Psyllium seed husks are portions of the seeds of the plant Plantago ovata, (genus Plantago), a native of India. They are soluble in water, expanding and becoming mucilaginous when wet. Psyllium seed husks have also been used for binding dietary fats and preventing their absorption. However, although Psyllium seed husks act as a laxative in relatively small amounts, they can cause constipation when administered in the larger amounts needed for dietary fat removal.
Thus, at present, although numerous substances and combinations of substances have been used for binding dietary lipids in the GI tract so as to prevent uptake of the lipids, many are associated with problems that can limit their effectiveness and the extent to which they are used in many sections of the general population.
Summary of the invention
The present invention provides an improved composition for binding dietary lipids in the GJ tract and thereby preventing or reducing absorption of the Jipids. In this way, the compositions provide a means of combatting obesity and hyperlipidaemia.

Opuntia ficus indica is a cactus found in Central and South America. The cactus produces "cladodes" or truncated branches of the stem that contain chlorophyll and are adapted to carry out photosynthesis. The cladodes have a leaf-like appearance but are not true leaves. In the present context, the term "leaf material from Opuntia ficus indica" refers to the cladodes.
The term plant material" includes material derived from the cladodes or from other parts of the plant such as the plant stem.
In one preferred embodiment, the plant material is derived from the cladodes or leaves of the plant.
The cladodes or other parts of the plant are dried and then ground to a powder in which at least 99.5% by weight of the particles have a maximum dimension (e.g. S diameter) of less than 300 pM. More typically, at least 70% by weight of the particles have a maximum dimension (e.g. diameter) of less than 100 pM.
Further details of the preparation of powdered plant material from Opuntia ficus indica may be found in US2004/0 126444.
The powdered plant material is presented in the form of a powder. The plant material may be presented in powder form wherein at least 99.5% by weight of the particles forming the powder have a particle size (e.g. diameter) of 600 pM or less.
Such particles will pass through a 30 mesh sieve. In one embodiment, at least 99.5% by weight of the particles have a particle size (e.g. diameter) of 400 pM or less. Such particles will pass through a 40 mesh sieve. In another embodiment, at least 99.5% by weight of the particles have a particle size (e.g. diameter) of 300 pM or less. Such particles will pass through a 50 mesh sieve. In a further embodiment, at least 95% by weight of the particles have a particle size (e.g. diameter) of 210 pM or less. Such particles will pass through a 70 mesh sieve. In another embodiment, at least 75% by weight of the particles will pass through a 50 to 60 mesh sieve and have particle sizes in the range from 230 to 280 pM.
The compositions of the invention are typically administered with or without (but preferably with or shortly before or after) meals one or more times per day. For example, the compositions may be administered from two to four times per day.
The compositions may be administered so that the daily intakes of the three components are as follows: Powdered plant material from Opuntia ficus indica: 100 mg to 1600 mg Powdered Psyllium husk: 50 mg to 600 mg Chitosan: 50 mg to 600 mg The compositions of the invention bind fats and other lipids in the GI tract and carry them through so that they are excreted with the faeces. In this way, the fats and other lipids cannot be absorbed by the body. By mopping up a large proportion of the fats in food consumed by a subject, obesity and hyperlipidaemia may be prevented.
The invention will now be illustrated but not limited, by reference to the following
specific example.
