Description

Pharmaceutical composition with a content of calcium or mixture of calcium and vitamin D or mixture of calcium and magnesium in a new formulation
Technical Field
The invention from the pharmaceutical field relates to a therapeutical preparation with the content of calcium or mixture of calcium and vitamin D or mixture of calcium and magnesium for a long-term peroral use for prevention and treatment of primary and secondary osteoporosis and for correction of hyperphosphataemia in patients in advanced stages of renal insufficiency.
Background Art
It is well known, that some patients suffer from a deficit of calcium despite of its sufficient intake in diet. The reason is the impaired resorption in intestine cells.
The formulations with a content of calcium, known in the art, have used as a source of calcium its chemically defined therapeutic acceptable compounds, mainly in the form of effervescent tablets, tablets, solutions, powders and the like, or as a source have served treated animal and mineral raw materials.
The drawback of the e.g. effervescent tablets, is the fact, that after a longer time they are refused by patients, because they can, in addition to others, induce shifts in the acid-base balance to a metabolic alkalosis, the transport of calcium into bloodstream is fast and calcium concentration may exceed the safe level to cause temporary hypercalcaemia, which is dangerous from the point of view of origin and development of atherosclerosis.
In the case, that improperly selected calcium compound as e.g. calcium chloride is used, the preparation can at a long-term administration induce metabolic acidosis connected with increasing washing up of calcium from the bony mass. The drawback of biopreparations can be the presence of undesirable admixtures and non-standard content of biologically usable cations.
Another drawback is more time, raw materials and energy consuming manufacture.

After accomplished homogenization, sodium hydrogenphosphate and sodium phosphate pre-adjusted through a screen having the mesh side of 1.25 mm are stepwise added. In a special device for homogenization of small amounts colecalciferol is diluted with the mixture prepared before in the ratio of 1 : 50. Diluted colecalciferol is transferred into the mixture prepared before and admixed by intensive agitation until homogeneity is reached. Then powdered coconut aroma is added to the mixture. After homogenization is completed, the mixture is prepared to be adjusted into a combined three-layer foil PP/AI/PE in the doses of 3.000 g, what is one dose and this contains 500 mg of biologically usable calcium and 800 I.U. of vitamin D3.
Example 6
a) pharmaceutical composition, containing in 1 dose:
Magnesiumhydroxidecarbonate 0.7880 g 26.26 %
Calcium carbonate 0.6237 g 20.79 %
Saccharose 0.9749 g 32.50 %
Starch derivative 0.4682 g 15.61 %
Carageenan 0.0122 g 0.40 %
Sodium hydrogenphosphate 0.0076 g 0.25 %
Sodium phosphate 0.0304 g 1.01 %
Citric acid 0.0300 g 1.00 %
Sodium citrate 0.0100 g 0.33 %
Powdered citric aroma 0.0250 g 0.83 %
Maltodextrin 0.0210 g 0.70 %
Dimethylpolysiloxane 0.0090 g 0.30 %
b) process for its preparation:
Micronized magnesium hydroxidecarbonate and calcium carbonate are admixed in a suitable apparatus with a half amounts of saccharose and starch derivative. Carageenan is added, the mixture is perfectly commixed and the rests of saccharose and starch derivative are added. After accomplished homogenization previously homogenized mixture of sodium hydrogenphosphate, sodium phosphate, citric acid and sodium citrate with the adjusted size of particles through a screen of the mesh side of 1.0 mm is added to this mixture. When homogenization of these mixtures is completed, dimethylpolysiloxane, maltodextrin and powdered citric aroma are stepwise added. After reaching homogeneity confirmed by an analysis the mixture is adjusted into one-dose sachets from a combined three-layer foil, with doses in the amount of 3.000 g. This way prepared 1 dose contains 200 mg of biologically usable magnesium and 250 mg of biologically usable calcium
Clinical evaluation
Administration of calcium is essential part of every treatment or prevention of osteoporosis, wherein it is necessary to ensure a daily uptake of 400 to 800 I.U of vitamin D.
In the monocentric open controlled clinical study was proved similar bioavailability of calcium after single administration of the composition according to the invention in comparison with standard preparation in an effervescent tablet form, wherein distinctly higher calcaemia after 1 hour after administration of effervescent tablet was found out. Gradual increasing of calcaemia not exceeding the upper limit of the standard, is very desirable especially in elderly population where hypercalcaemia is connected with the risk of calcium deposition into atherosclerotic plates.
In the monocentric open uncontrolled tolerance clinical study with adult patients having osteoporosis or having insufficient intake of calcium in diet excellent tolerance and safety of the composition according to this invention was proved. The two month administration of followed up composition of the invention resulted in statistically significant increase of calcaemia in the whole group of 76 patients having osteopenia or osteoporosis proved by densitometry and having insufficient intake of calcium. Characteristics of clinical studies with a composition of calcium according to the invention
Industrial Applicability
The invention is useful in the pharmaceutical industry in the manufacture of therapeutic preparations for treatment and prevention of osteoporosis.
