PHARMACEUTICAL PREPARATIONS
FOR THE TREATMENT OF ARTHRITIS
Field of the Invention
The invention pertains to compositions for treating arthritis in
humans and animals.
Background of the Invention
Medications for oral administration are known for the treatment of
arthritis which contain glucosamine, protein and various herbal materials
or extracts. It has been discovered by the present inventors that the
addition of certain compositions including minerals to such medications
can produce a medication having an enhanced effectiveness in treating
arthritis, and in particular in helping to form connective tissue in the
afflicted joints and to prevent further cartilage deterioration.
Summary of the Invention
The invention provides a pharmaceutical composition for treating
arthritis comprising glucosamine or a salt thereof, plant materials or
extracts, collagen, pantothenic acid, and minerals. The glucosamine salt is
preferably glucosamine sulphate. The minerals are preferably copper,
manganese and selenium. The composition can be made in a form for oral
administration, such as a capsule, and each capsule preferably contains at
least 375 mg of glucosamine sulphate, 5 mg of pantothenic acid, 350 mg of
copper, 750 mg of manganese and 13 mcg (micrograms) of selenium, in
addition to the other components. The combination in the composition of
the mineral components with the glucosamine and the plant materials
produces a synergistic action in treating the arthritis and the pain caused by
it.

These and other features of the invention will be apparent from the
following description of the preferred embodiments.
Description of the Preferred Embodiments
The pharmaceutical compositions of the invention are for oral
administration and comprise components which serve a number of
necessary functions in effectively treating arthritis. These functions
include relieving pain, relieving inflamation, rebuilding cartilage and
preventing cartilage deterioration. The compositions comprise
glucosamine or a salt thereof, plant materials, collagen, pantothenic acid
(Vitamin B5), and minerals, preferably copper, manganese and selenium.
Glucosamine is an amino acid derivative. It is used in the
composition to protect against deterioration of cartilage and contribute to
the building of heathy cartilage. It is preferably in the form of one of its
salts, such as glucosamine sulphate (which is preferred) or glucosamine
hydrochloride. One dose of the composition contains approximately 375
mg of glucosamine sulphate, or the equivalent amount of glucosamine in
another form.
The plant materials or extracts that are components of the
composition are preferably boswellia extract, white willow bark, yucca
root powder, devil's claw, sarsaparilla, feverfew leaf powder and
bromelain.
Boswellia extract acts as an anti-inflammatory agent. The preferred
form used in the composition is derived from Boswellia serrata and is
standardized to contain about 65% boswellic acid. One dosage of the
composition contains approximately 10 mg of boswellia extract.

White willow bark acts as a pain reliever in the composition. It is
preferably prepared from Salalix alba in a form standardized to 25%
salacin. One dosage of the composition contains approximately 50 mg of
white willow bark.
Yucca root powder acts as an anti-inflammatory agent in the
composition. It is derived from Yucca schidigera. One dosage of the
composition contains approximately 15 mg of yucca root powder.
Devil's claw acts as an anti-inflammatory agent in the composition.
It is derived from Harpagophytum procumbens. One dosage of the
composition contains approximately 15 mg of devil's claw.
Sarsaparilla acts as an anti-inflammatory agent in the composition.
It is derived from Smilax sp. One dosage of the composition contains
approximately 15 mg of sarsaparilla.
Feverfew leaf powder acts as a pain reliever in the composition. It
is derived from Tanacetum parthenium. One dosage of the composition
contains approximately 10 mg of feverfew leaf powder.
Bromelain acts as an anti-inflammatory agent in the composition.
One dosage of the composition contains approximately 5 mg.
The collagen used in the composition is preferably Type II collagen.
The unhydrolyzed form is preferred for ready absorption into the body
tissues. Collagen promotes the rebuilding of cartilage. One dosage of the
composition contains approximately 30 mg of collagen.

Pantothenic acid is a component of the composition and promotes
tissue formation. One dosage of the composition contains approximately 5
mg.
The preferred minerals in the composition are copper, manganese
and selenium. Copper helps produce red blood cells and connective tissue.
One dosage of the composition contains approximately 350 mcg of copper.
Manganese is a component that acts in the process of bone
metabolism. One dosage of the composition contains approximately 750
mcg of manganese.
Selenium is a non-metallic mineral component of the composition
that is a factor in the maintenance of health body cells and tissues. One
dosage of the composition contains approximately 13 mcg of selenium.
The composition of invention is made by the following method. A
mixture of the glucosamine sulphate, the collagen and the plant materials
or extracts, all of which are in dry powdered form, is prepared. A second
mixture is prepared comprising the pantothenic acid and the copper,
manganese and selenium. These two mixtures are mixed together and the
resulting powdered mixture is used to prepare single-dosage capsules.
Alternatively, the composition and/or the second mixture (the pantothenic
acid, copper, manganese and selenium) can be used by topical
administration.
