Description

PHARMACEUTICAL COMPOSITION COMPRISING ZALTOPROFEN, GLUCOSAMINE, CHONDROITIN, HYALURONIC ACID FOR JOINT

AND CARTILAGE DISORDERS

Field of Invention

The present invention, relates to a pharmaceutical composition comprising zaltoprofen, glucosamine, chondroitin and hyaluronic acid which has therapeutic effect against pain and inflammatory symptoms associated with joint and cartilage disorders, especially with osteoarthritis and rheumatoid arthritis.

Background of Invention Joint and cartilage disorders, is a painful degenerative condition that results in the deterioration of cartilage tissues that support the weight-bearing joints in the body. Once the cartilage is thinned or lost, the constant grinding of bones against each other causes pain and stiffness around the joint. Abnormal and excess bone formations called spurs grow from the damaged bones, causing further pain and stiffness. It is believed that degenerative joint disorders affect 80% of people over the age of 60. Degenerative joint disorders include, for example, osteoarthritis, rheumatoid arthritis, other rheumatic disorders with cartilage breakdown, chondrolysis after joint trauma, for example, after meniscus or patella injuries or torn ligaments, or chondrolysis associated with prolonged immobilization of joints. Osteoarthritis is the most prevalent form of arthritis which is a painful, degenerative joint disease that often involves the hips, knees, neck, lower back, or the small joints of the hands. It is characterized by pain and progressive degeneration of cartilage in synovial joints and vertebrae, leading to significant reduction of mobility and quality of life. Osteoarthritis usually develops in joints that are injured by repeated overuse in the performance of a particular job or a favorite sport or from carrying around excess body weight. Eventually this injury or repeated impact thins or wears away the cartilage that cushions the ends of the bones in the joint so that the bones rub together, causing a grating sensation. Joint flexibility is reduced, bony spurs develop, and the joint swells. Usually, the first symptom a person has with osteoarthritis is pain that worsens following exercise or immobility.

Rheumatoid arthritis is an autoimmune inflammatory disease in which the body releases enzymes that attack its own healthy tissues. In rheumatoid arthritis, these enzymes destroy the linings of joints causing pain, swelling, stiffness, deformity, and reduced movement and function. Rheumatoid arthritis also may include systemic symptoms.

Hence, pharmacological treatment of arthritis involves two therapeutic goals:

· Analgesic & anti-inflammatory treatment: Relief from pain and inflammation of the soft tissue surrounding the joint.

• Disease-modifying treatment to treat the underlying pathology.

Zaitoprofen is a propionic acid derivative, is a known NSAID (non-steroidal anti-inflammatory drug) with analgesic and anti-inflammatory activity. Its chemical structure is shown in the Formula I.

Formula I. Zaitoprofen The chemical name of zaitoprofen is 2-(10-oxo-10,1 1 -dihydrodibenzo[b,f]thiepin-2- yl)propanoic acid. It is a preferential COX-2 inhibitor. It selectively inhibits PGE2 (Prostaglandin E2) that mediates the pain pathway. It inhibits bradykinin-induced pain responses without interfering with the bradykinin receptors. It is used in musculoskeletal and joint disorders such as osteoarthritis and rheumatoid arthritis and other chronic inflammatory pain conditions or the treatment of lumbar pain, frozen shoulder, musculoskeletal pain, dental pain, post-operative pain, cervicobrachial syndrome, other pain and inflammatory conditions. It has also effect on post-surgery or post trauma chronic inflammation.

Glucosamine is an amino sugar and a prominent precursor in the biochemical synthesis of glycosylated proteins and lipids. Glucosamine is part of the structure of the polysaccharides chitosan and chitin and it is naturally present in the shells of shellfish, animal bones and bone marrow. It is also present in some fungi and can be also synthetically derived. Glucosamine is used for the treatment of osteoarthritis. Its chemical name is (3R,4R,5S)-3-Amino-6- (hydroxymethyl)oxane-2,4,5-triol. Chemical structure of glucosamine sulfate (GS) is shown in the formula II. Recent studies indicate that it also slows the deterioration of cartilage and relieves pain. Tablet form of glucosamine sulfate is authorized in the strength of 500 and 750mg. Daily recommended dose is between 500 to 2500 mg.

Formula II. Glucosamine sulfate

Chondroitin sulfate (CS) is a sulfated glycosaminoglycan (GAG) composed of a chain of alternating sugars. Chondroitin sulfate is an important structural component of cartilage and provides much of its resistance to compression. Chondroitin sulfate is mostly administrated orally. Tablet form is authorized in the strength of 120, 250 and 400mg and daily recommended dose is 1200mg. Chemical structure of chondroitin sulfate is shown in the formula III.

Formula III. Chondroitin sulfate

In the state of art, there are capsule and tablet forms of glucosamine and chondroitin combination authorized in U.S. The main benefit of glucosamine and chondroitin combination is prevention of cartilage degeneration in the joints, especially in those affected by osteoarthritis. It also helps to reduce the pain associated with overuse conditions, such as knee tendonitis and other sports-related injuries and helps to reduce inflammation while increasing the health of the muscle and other tissue. US 2008/0227747 A1 discloses a therapeutic composition and methods for the treatment and prevention of a degenerative joint disorder and/or cardiovascular disease comprising polycosanols, glucosamine and chondroitin. Composition further may comprise NSAIDs, but neither an example nor zaltoprofen as one of the NSAIDs is disclosed in the patent application in combination with glucosamine. Hyaluronic acid (HA) exists as a naturally-occurring polysaccharide (also known as a mucoid polysaccharide) that can be extracted from such diverse sources as rooster comb, umbilical cord, vitreous humor, synovial fluid, pathologic joints, skin and group A and C hemolytic Streptococci. The hyaluronic acid is also defined as a high viscosity naturally occurring glycosaminoglycan having a polymeric structure containing alternating N-acetyl-D- glucosamine and D-glucuronic acid monosaccharide units linked with [beta] 1 -4 bonds and the disaccharide units linked with [beta] 1 -3 glycoside bonds

Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan. It is ubiquitous in the organism, with the highest concentration found in soft connective tissue and joint fluid. It is a constituent of the intercellular matrix of connective tissue that exists in almost all vertebrates. It plays an important role in a number of physiological functions, including protection and lubrication of cells, maintenance of the structural integrity of tissues, transport of molecules and cells, cell migration, cell function and differentiation, and fluid retention and regulation.

Natural Hyaluronic acid is polydisperse in respect of molecular weight and is known to show excellent biocompatibility even when implanted or injected into the body by virtue of the absence of species and organ specificity. However, because of the relatively short in vivo residence time of Hyaluronic acid solution in biological applications, improvements in the persistency of Hyaluronic acid by chemical crosslinking with various chemical modifiers has been attempted to broaden its use for medical materials.

Hyaluronic acid is an important component of the intercellular matrix. Specifically, the highest levels are found in the eye and synovial fluid of joints. In joints, its primary role is that of lubrication, reducing pain, and inflammation. In arthritic joints HA is deficient. In regards to the joints, synovial fluid supplies nutrition to the articular cartilage and has incomparable functions as a lubricant and a shock absorber. It is clarified that its excellent viscoelastisity heavily owes to one of the main components, Hyaluronic acid. Concentration and molecular weight analyses of Hyaluronic acid demonstrated the concentration and molecular weight of Hyaluronic acid in the synovial fluid from patients with arthritis such as osteoarthritis and chronic articular rheumatism generally tended to be lower than in normal synovial fluid, and the lower concentration and molecular weight of Hyaluronic acid were closely associated with development of locomotor dysfunction and pain attributable to the weaker lubricating action and the weaker protecting action on the surface of the articular cartilage of synovial fluid. Chemical structure Hyaluronic acid is shown in the formula IV.

Formula IV. Hyaluronic acid

Methylsulfonylmethane (MSM) is an organosulfur compound with the formula (CH 3) 2SO 2. It occurs naturally in some primitive plants, is present in small amounts in many foods and beverages, and is marketed as a dietary supplement. MSM is sold as a dietary supplement and marketed with a variety of combinations, often in combination with glucosamine and/or chondroitin for helping to treat or prevent osteoarthritis. Small-scale studies of possible treatments with MSM have been conducted on both animals and humans. These studies of MSM have suggested some benefits, particularly for treatment of osteoarthritis. A review by Brien, et al., (Systematic review of the nutritional supplements dimethyl sulfoxide ( DMSO) and methylsulfonylmethane (MSM) in the treatment of osteoarthritis, Osteoarthritis and Cartilage, 2008; 16:1277) of the two small randomized controlled trials of methylsulfonylmethane in osteoarthritis knee pain relief reported significant improvement in pain outcomes in the treatment group compared to comparator treatments. After several reports that MSM helped arthritis in animal models, one study by Usha et al. (Double- blind, parallel, placebo- controlled study of oral glucosamine, methylsulfonylmethane and their combination in osteoarthritis, Clinical Drug Investigation, 2004; 24:353-63) had confirmed that 1 .5 g per day MSM (alone or in combination with glucosamine sulfate) was helpful in relieving symptoms of knee osteoarthritis. Chemical structure methylsulfonylmethane is shown in the formula V.

Formula V. Methylsulfonylmethane (MSM) There are various patent applications relates to joint and cartilage disorders in prior art in relation to separately or combinations of 2 or 3 active agents but not all 4 or 5 active agents in combination in one dosage form. In addition, none of them are specifically comprises zaitoprofen, glucosamine sulfate, chondroitin sulfate and hyaluronic acid in oral administration as tablet dosage form.

A commercial dietary supplement, Flex-A-Min(R), is reported to provide a combination of glucosamine, chondroitin sulfate and methylsulfonylmethane, and is directed at subjects with arthritis and joint pain. However, no pharmaceutical composition has been produced until today, which contains a combination of zaitoprofen, glucosamine, chondroitin and hyaluronic acid. Even if some medicaments comprising either of these active agents have been administered concomitantly in practice, this fact requires the patients to carry more than one drug and causes application-related difficulties. Additionally, administering and formulating a combination, in place of the individual use of each active agent, may provide improved treatment features.

However, it is well known that drugs used in the same therapeutic area or even for treating the same indication cannot always be combined a priori with the expectation of at least additive therapeutic effects. The scientific literature is full of examples wherein compounds of different classes, which are used to treat the same indications, cannot be combined into safe and efficacious dosage forms thereby resulting in incompatible drug combinations. The reasons for this unexpected lack of compatibility are varied; however, it is often found that the incompatible drug combinations result in increased side effects, unwanted drug interactions or new side effects.

Another problem is related to combine these four active ingredients in one dosage form such as tablet or capsule, it would require a dosage form having approximately or more than 1000 mg active ingredients in total without any further tablet or capsule excipients. This is an amount that would create a very large tablet or capsule size that would not be swallowable or it would require composition that would require ingesting multiple tablets to achieve the desired effect.

Accordingly, based on said drawbacks, a novelty is required in the art of pharmaceutical combinations having therapeutic effects against pain and inflammatory symptoms associated with joint and cartilage disorders, especially with osteoarthritis and rheumatoid arthritis. In this present invention, the object is to provide a new pharmaceutical composition comprising zaitoprofen, glucosamine sulfate, chondroitin sulfate and hyaluronic acid. In further, the present invention also provides zaitoprofen, glucosamine sulfate, chondroitin sulfate, hyaluronic acid and MSM as a dietary supplement. Detailed description of the invention

In the main embodiment of this present invention is to provide a pharmaceutical composition comprising zaitoprofen, glucosamine, chondroitin and hyaluronic acid or their pharmaceutically acceptable salts thereof and at least one pharmaceutically acceptable excipient.

The pharmaceutical composition of this present invention is to provide improved treatment of degenerative joint and cartilage disorders by administering to a subject in need thereof a therapeutically effective amount of a pharmaceutical composition comprising zaitoprofen, glucosamine , chondroitin and hyaluronic acid or their pharmaceutically acceptable salts thereof and at least one pharmaceutically acceptable excipient which overcomes the above described problems in prior art and have additional advantages over them.

An embodiment of this present invention is to eliminate the Gl adverse effects of zaitoprofen when it is administered orally in high terapeutic effective amounts for a long time. It is known that the treatment of the degenerative joint and cartilage disorders, especially osteoarthritis and rheumatoid arthritis needs a long treatment period. Therefore to use of zaitoprofen for a long time with high terapeutic effective amounts may increase the possibility of Gl adverse effects of zaitoprofen. As a rule, after a long-term administration of a drug, drug addiction develops and as a consequence its dosage should be increased. This certainly affects the occurrence of side effects.

The present invention provides the solution to this problem by using the amount of zaitoprofen is not more than 15 % by weight of the total composition by combining it with glucosamine sulfate, chondroitin sulfate, hyaluronic acid, methylsulfonylmethane. It has been found surprisingly that this ratios have an increased/synergistic effect over analgesic and antiinflammatory activity of zaitoprofen even with low doses.

Accordingly, when zaitoprofen is used for a long period of time, it may have a desensitizing effect. It has been also found that when zaitoprofen is used by combination with glucosamine, chondroitin and hyaluronic acid makes it possible to ensure increased analgesic and anti-inflammatory effect of the composition, whilst reducing the pain and inflammation syndrome in degenerative joint and cartilage disorders synergistically. Thus this qualify to use zaitoprofen in low dosage for patients also reduces the risk of the Gl side effects. In one embodiment, salt of glucosamine used in this present invention is selected from the group comprising glucosamine sulfate, N-acetyl-glucosamine, glucosamine hydrochloride, glucosamine sodium hydrochloride, glucosamine potassium chloride, glucosamine sulfate sodium and mixtures thereof. Preferably, salt of glucosamine is glucosamine sulfate. The role which glucosamine sulfate plays in the treatment or prevention of the degenerative joint and cartilage disorders is most likely associated directly its ability to act as the most important substrate for glycosaminoglycans and a basis of hyaluronic acid. A successful treatment of osteoarthritis and rheumatoid arthritis must control pain effectively as well as slow down or ensure the reverse development of joint degeneration process. In this present invention, it has been found that the introduction of the amount of glucosamine sulfate is not more than 45 % by weight of the total composition makes it possible to ensure a chondroprotective and anti-inflammatory effect of the composition and prevents destructive effect of glucocorticoids on chondrocytes and to reduce a need for NSAID (i.e.zaltoprofen) in high dosage for patients suffering from osteoarthritis and rheumatoid arthritis which in turn makes it possible to decrease side effect risks.
