Description

Collagen oral preparation and preparation method

The invention belongs to biochemical drug.Be specifically related to a kind of collagen oral preparation and preparation method.

Rheumatoid arthritis is a kind of systemic autoimmune disease based on chronic polyarthritis.Existing medicine for treatment roughly is divided into two classes: the special symptomatic treatment medicine of class right and wrong, for example aspirin, adrenocortical hormone and NSAID (non-steroidal anti-inflammatory drug) etc., but the side effect of this class medicine mainly causes gastritis, even gastrorrhagia, to central force depletion, liver, the careful usefulness of kidney patient; Another kind of is the antirheumatic that improves the state of an illness, and for example thio phenyl fruit acid gold sodium, penicillamine, Radix Tripterygii Wilfordii, chloroquine etc., but this class preparation is except that having gastrointestinal reaction are also with albuminuria and fall leukocyte or symptom such as thrombocytopenia.The cause of disease of rheumatoid arthritis is not clear so far, and patient's redness and swelling of joints, pain also deform, and pathological characters is collagen fiber degraded and joint cartilage.METHOTREXATE (methotrexate), CYCLOSPORINA (cyclosporin A) and AZATHIOPRINE (sulfur azoles Piao purine) have been used to treat rheumatic arthritis and relapsing polychondritis.But they are nonspecific immunosuppressive drugs, have cytotoxicity, take for a long time and can reduce patient's immunologic function.In the last few years, people be devoted to use Chinese medicine " with dirty control dirty " principle, animal cartilage is applied to treat rheumatic arthritis and relapsing polychondritis.But because of only adopting simple decocting method can not extract main effective ingredient in the cartilage effectively, thereby influenced curative effect.

The main component of chondroprotein is a collagen, contains in the collagen protein by three protein chains to constitute the triple helix structure.Collagen protein in the cartilage is mainly to be type and a small amount of IX, XI collagen type.Type is made up of three identical protein chains, and the IX type is made up of three different protein chains with the XI collagen type, and these three kinds of collagen albumen constitute the chondrigen fiber together.Collagen fiber are except the mechanical strength that can keep cartilage, and also by the extracellular matrix receptor combination of its RGD aminoacid sequence and cell surface, the signal that is transmitted has guaranteed existence, growth and the differentiation of chondrocyte.In cartilage, collagen fiber are by hyaluronic acid and the embedding of chondroitin sulfate institute, so the solubility of chondrigen is extremely low.

The objective of the invention is to overcome above-mentioned weak point, develop a kind of chondrigen preparation of solubility.The inventor utilizes protease digestion to make the chondrigen fiber change the tropocollagen molecule of solubility into, and the enzymology cartilage is applied to treatment to rheumatic arthritis and relapsing polychondritis.

The invention provides a kind of collagen oral preparation.Said preparation is formed as main active and pharmaceutic adjuvant with type, and they can be 0.0001%-99.9999% and contain the composition that medicinal adjuvant is any proportioning formation 100% of 99.9999%-0.0001% by the type that contains as active component.

Another object of the present invention has provided a kind of preparation method of above-mentioned type oral formulations.This method is to get animal cartilage, adds the normal saline homogenate that 5-10 doubly measures, and centrifugal collection is heavy, uses absolute ethanol washing, and is centrifugal.Collecting precipitation, precipitation is dissolved in the buffer of sodium acetate PH＜4 of 0.01-0.8mol/L, w/v is 1: 10-60, low temperature (0-10 ℃) is placed and is spent the night, adding concentration is that the pepsin or the concentration of 0.01-4 mg/ml is the trypsin of 0.01-50 mg/ml, low temperature (0-10 ℃) is placed and is spent the night, centrifugal, get supernatant, add sodium chloride 0.5-4mol/L, placement is spent the night, centrifugal, collecting precipitation is dissolved in the acetum (or adding the 1-5% extender) that 20-50 doubly measures PH＜5, promptly make the type raw material after the lyophilizing, according to a conventional method this raw material and pharmaceutic adjuvant are mixed with oral tablet then, capsule, powder, granule, water preparation, pharmaceutical preparatioies such as lyophilized preparation.

The pharmaceutic adjuvant that the present invention uses be the binding agent of routine such as starch, hydroxypropyl starch, modified starch, pregelatinized Starch, dextrin, Icing Sugar, microcrystalline Cellulose, gelatine size, PVP rubber cement; Disintegrating agent is carboxymethyl starch sodium, starch, microcrystalline Cellulose; Lubricant is modified starch, microcrystalline Cellulose, micropowder silica gel, aluminium hydroxide; Extender is starch and derivant, cellulose and derivant, inorganic compound, organic salt and hexose acids or pentitol.

It is to take every day to contain type 2-1000 μ g that type oral formulations of the present invention is used for clinical dosage.

Adopt method of the present invention, the cartilage of 50-90% can be dissolved, and the proteic response rate of chondrigen can reach 60-80%.

The type that extracts in the inventive method sees Table 1 through physics and chemistry method qualification result, has shown that collagen protein has kept their complete of triple helix structure in the enzymology cartilage.
