Definitions
- the present invention relates to a composition comprising a mixture of chondroitin sulfate and glucosamine and to an oral dosage form comprising the aforementioned composition.
- Pharmaceutically active substances can be formulated as single-dose solid drug forms in the form of tablets and these represent a common oral dosage form.
- the shape of the tablets is different and for oral use have biconvex forms (round, oblong, arched top and bottom) prevailed.
- Tablets can be made by compressing from powders or granules by means of tablet presses.
- binders are often added to a composition containing a pharmaceutically active substance to after pressing a
- the powdered or granular compositions which are made into tablets in a tablet press must also be sufficiently fluid. Furthermore, it may be desirable for the weight percent of pharmaceutically active substance per tablet to be high. On the one hand, there are often therapeutic reasons to administer high daily doses. This is simplified if only a few or only one tablet per day must be taken orally, which then necessarily contains a high proportion of active ingredient. On the other hand, it may be desirable for the tablet to be as small as possible in order to facilitate oral administration in, for example, children or the elderly. This also requires a high proportion of active ingredient in the tablet. However, high proportions of active ingredient lead to a deteriorated hardness of the tablet, which should be avoided.
- a measure of the flowability of a composition is, for example, the determination of the angle of repose ⁇ of a spilled sample.
- the angle ⁇ between the bottom surface and the conically poured sample of the composition to be investigated is determined.
- the angle of repose ⁇ correlates with the processability of a composition within a tablet press.
- Lower slope angles ⁇ of a spilled sample indicate improved processability within a tablet press. This reduces the likelihood of production disruption within a tablet press.
- compositions which contain a high level of pharmaceutically active substance and from which tablets of sufficient hardness can be obtained.
- flowability of the composition must be within a tablet press so that efficient compression of the composition into tablets is ensured. This results in particular in the technical problem of providing compositions with a low angle of repose ⁇ of a bulk sample.
- the object of the prior art is to provide a composition containing a large proportion of chondroitin sulfate and glucosamine or their pharmaceutically acceptable salts.
- the technical object of the present invention is obtained by a composition
- At least 70% by weight of at least one pharmaceutically active substance which is a mixture of chondroitin sulfate and glucosamine or their pharmaceutically acceptable salts
- the composition contains at least 80% by weight of at least one pharmaceutically active substance which is a mixture of chondroitin sulfate and glucosamine or their pharmaceutically acceptable salts and 5 to 19.9% by weight of at least one binder, at least 30% by weight .-% of the binder has a particle size less than 70 ⁇ .
- the compositions of the present invention show an increase in the efficiency of a tablet press when preparing oral dosage forms. The angle of repose ⁇ of an accumulated sample is lower, which indicates improved flowability.
- the tablet hardness of an oral dosage form containing the aforementioned composition is sufficient.
- the at least one pharmaceutically active substance a) has a particle size based on the total content of pharmaceutically active substance of at least 50% by weight greater than 50 ⁇ m.
- the particle size distribution can be determined by sieve analysis or laser diffraction.
- the at least one pharmaceutically active substance a) preferably contains at least 30% by weight of chondroitin sulfate sodium and at least 50% by weight of glucosamine HCl.
- At least 30% by weight of the at least one binder b) contained in the composition has a particle size of less than 70 ⁇ m.
- the particle size distribution can be determined by sieve analysis or laser diffraction.
- the at least one binder b) has a particle size of at least 40% by weight of less than 70 ⁇ m and more preferably of 50% by weight of less than 70 ⁇ m.
- the at least one binder b) is a dry binder.
- the binder b) is selected from the group consisting of starch, cellulose, modified cellulose, copolymers of polyvinylpyrollidone with polyvinyl acetate or mixtures thereof.
- the binder b) is selected from the group consisting of hydroxypropyl cellulose, microcrystalline cellulose and mixtures thereof.
- At least 90% by weight of the at least one filler c) contained in the composition has a particle size of less than 1 ⁇ m.
- the particle size distribution can be determined by sieve analysis or laser diffraction.
- the at least one filler has a particle size of at least 90 wt .-% less than 0.5 ⁇ on.
- the filler e) primary particles having a particle size based on the total content of filler of at least 90 wt .-% less than 1 ⁇ , more preferably of at least 90 wt .-% less than 0.75 ⁇ and most preferably of at least 90 wt .-% less than 0.5 ⁇ on.
- the at least one filler c) is preferably an inorganic or organic filler.
- the filler c) is more preferably selected from the group of silicic acid, fumed silica, precipitated silica, kaolin, calcium carbonate, zinc oxide, aluminum oxide, titanium dioxide, silicon dioxide, aluminum hydroxide, colloidal silicon dioxide or mixtures thereof.
- the filler c) has a specific surface area (BET) of more than 100 m 2 / g.
- composition preferably contains further additives d), such as microcrystalline cellulose, lactose, disintegrants, lubricants, e.g. Magnesium stearate, and / or antioxidants.
- additives d such as microcrystalline cellulose, lactose, disintegrants, lubricants, e.g. Magnesium stearate, and / or antioxidants.
- Another object of the present invention is an oral dosage form containing the aforementioned composition.
- the oral dosage form is a tablet.
- the oral dosage form is preferably used in the treatment of degenerative joint diseases.
- the degenerative joint disease is osteoarthritis, coxarthrosis, finger joint arthrosis and / or polyarthritis.
- Another object is the aforementioned composition for use in the treatment of degenerative joint disease.
- the degenerative joint disease is osteoarthritis, coxarthrosis, finger joint arthrosis and / or polyarthritis.
- compositions by mixing the active ingredients with
- Magnesium stearate various binders and a filler.
- Amounts of the ingredients are constant in Examples 1 to 3.
- Example 3 A composition with equal proportions of chondroitin sulfate sodium and glucosamine HCl is prepared as in Example 1, but with Klucel® as a binder.
- Example 3 A composition with equal proportions of chondroitin sulfate sodium and glucosamine HCl is prepared as in Example 1, but with Klucel® as a binder.
- compositions 1-3 are shown in Table 1. Table 1
- Aerosil ® 200 used is a filler (fumed silica) and has a particle size with d (go) ⁇ 0.5 ⁇ on.
- Comparative Examples A to E compositions are prepared either without filler or with 4 times the amount of filler by mixing.
- the fluidity of the compositions of Examples 1 to 3 and Comparative Examples A to E is determined by measuring the angle of repose ⁇ in °. The steeper (larger) the angle of repose of an accumulated sample, the lower the flowability. In each case 50 g of the composition are passed through a flow opening of 10 mm diameter on a bottom plate with a diameter of 10 cm. The slope angle is measured by means of a laser (ERWEKA GTB, ERWEKA ® GmbH). The results are summarized in Table 3.
- compositions of Examples 1 to 3 of the present invention containing 0.25 wt .-% filler have the best flowability and Tablettier sadness. With a higher proportion of filler, the flowability and tabletting decreases. The same applies if no filler is present in the compositions.
- the tablet hardness of tablets prepared from the aforementioned compositions of Examples 1 to 3 and Comparative Examples A to E is determined.
- the compositions are pressed into tablets at 20 kN pressing force in an eccentric press and the tablet hardness in [N] bestimnnt. A higher value corresponds to a greater hardness.
- Table 5 The results are shown in Table 5.
- compositions of Examples 1 to 3 of the present invention containing 0.25% by weight of filler after pressing have sufficient tablet hardness.
- the compositions of Examples 1 to 3 of the present invention and tablets made therefrom have an advantageous combination of flowability, tabletability and tablet hardness. This result is surprising to the person skilled in the art.
