Description

FORMULATION FOR OSTEOPOROSIS
The present invention relates to pharmaceutical formulations with high bioavailability comprising calcium, genistein and vitamin D in order to be used in prophylaxis and treatment of osteoporosis and related diseases. Bone loss, or in other terms "osteoporosis", is defined as a disease characterized by liability to bone fracture and increased risk of bone fracture as a consequence of low bone mass and deterioration of bone micro architecture. The disease does not generally result in death; however, it is a major health problem affecting life quality.
Although osteoporosis is mostly seen in spine, hip and wrist; all the bones in the body are affected by the disease. 80% of the patients are female though the disease is encountered in both genders. Postmenopausal women lose 0,7-2% of total bone mass annually while this ratio is 0,5-0,7% for men. In parallel with this, total bone mass loss in men and women between 45-70 years of age is 15-30%. Some studies conducted nowadays indicate that insufficient calcium intake in childhood may increase the risk of osteoporosis later in life. It is known that calcium taken by diet plays a significant role in prophylaxis of osteoporosis. However, calcium absorption is reduced in postmenopausal term due to physical features of calcium and other factors. One of the most important problems encountered in calcium intake is that calcium salts in all calcium sources do not dissolve at an equal rate or present desired bioavailability. Calcium salts have low water solubility. They are dissolved relatively better in gastric acid; however, carbon dioxide produced causes gas and pain in the stomach. Furthermore, gastric acid is reduced due to gastric acid inhibitors used in later ages and therefore calcium leaves the stomach without being dissolved.
Another factor for reduced calcium absorption in postmenopausal women is vitamin D deficiency. Vitamin D is a fat-soluble hormone precursor and the studies conducted have indicated that efficient amounts of vitamin D increases calcium absorption. Vitamin D deficiency is also seen in individuals who do not receive sufficient sunlight.
Various methods and formulations have been developed so as to prevent osteoporosis, to decrease the risk of osteoporosis occurrence and to treat osteoporosis; yet, none of these have attained to desired efficiency. It has been observed that use of calcium together with sex hormones, particularly with oestrogen is quite effective in preventing loss of bone mass but it has not been a frequently preferred method since this type of hormones facilitate development of carcinoma (breast, endometrial, ovary cancer). Although risk of carcinoma occurrence is less in calcium and oestrogen/progesterone treatment, there are still serious problems in this method, too. Researchers indicated that calcitonin, which is a calcium regulating hormone, can be used in osteoporosis treatment, particularly in postmenopausal osteoporosis treatment in the cases where oestrogen treatment is not suitable. Though yielded successful results, use of this treatment method has remained limited as the patients started to resist this treatment and it is high cost. Considering these studies conducted, it is clear that various hormones contribute to calcium intake. However, calcium and hormone combination has not been preferred due to the reasons such as side effects, resistance and cost. Nevertheless, with the use of genistein that is a phytoestrogen instead of oestrogen in recent years, bone mass could be increased without occurrence of the side effects observed in other hormone therapies. Moreover, it has been proved that genistein alleviates the symptoms observed in postmenopausal term such as hot flash and night sweat.
The studies conducted have indicated that use of vitamin D and genistein together is more effective compared with use of these agents separately or as dual combination.
With confirmation of this efficiency, the inventors have developed formulations comprising calcium, vitamin D and genistein. Tablet formulation comprising calcium, vitamin D and genistein that exists on the market now has been developed and put on the market in line with this purpose. However, it frequently poses problems to administer solid dosage forms such as pills, tablets, capsules by the oral route in elderly patients. Due to the problems appearing particularly in pharyngeal and esophageal movements, the individuals may have a feel of obstruction or asphyxiation, and as a result, intake of the medicament may turn disgustful and painful for the patient. Another disadvantage of tablet formulations comprising calcium is gas and pain in the stomach resulting from carbon dioxide produced while calcium is being dissolved in gastric acid. Furthermore, calcium leaves the stomach without being dissolved due to reduction of gastric acid in patients using gastric acid inhibitors and thus, the patient cannot benefit sufficient bioavailability.
When the prior art is taken into consideration, there is need for development of user-friendly formulations which comprise calcium, vitamin D and genistein; do not present the side effects such as gas and pain in the stomach that existing formulations pose in use; and have high bioavailability in order to be used in the prophylaxis and treatment of osteoporosis and related diseases.
The inventors have surprisingly found that effervescent formulations comprising calcium, vitamin D and genistein are more user-friendly, have fewer side effects and present higher bioavailability compared with tablet formulations; therefore, they display higher efficacy in the prophylaxis and treatment of osteoporosis and related diseases in comparison with existing formulations.
In this respect, the present invention relates to effervescent formulations comprising calcium, vitamin D and genistein. Effervescent formulation of the present invention can be in powder, granule, pellet, micro tablet or tablet form though it is preferably in tablet form.
Calcium used in the formulation of the present invention is preferably in salt form.

Formulation of the present invention comprises 5-60% calcium or calcium salt by weight.
Formulation of the present invention comprises 200-2000 mg calcium or calcium salt in an equal amount to this.
Considering that calcium salts have low water solubility in general, the inventors have encountered solubility problems in development of effervescent dosage forms comprising calcium or calcium salt. The inventors could attain to efficient solubility when they used calcium or calcium salt with a particle size smaller than 100 μηι, preferably smaller than 60 μηι.
In this aspect, the present invention relates to effervescent formulations comprising calcium or calcium salt with a particle size smaller than 100 μπι, preferably smaller than 60 μπι, vitamin D and genistein.
Vitamin D comprised in the formulation of the present invention can be vitamin D2 (ergocalciferol) or vitamin D3 (cholecalciferol) though it is preferably vitamin D3 (cholecalciferol). Formulation of the present invention comprises 0,01-15% vitamin D by weight.
