Description of the invention [Technical field to which the invention belongs] The present invention relates to an oral sustained release formulation of a poorly soluble main drug, such as an erythromycin derivative, which can be digested in the gastrointestinal fluid. The present invention particularly relates to a clarithromycin pharmaceutical composition which can be administered as a tablet daily. [Previous technology] Erythromycin and its derivatives are antibacterial agents, they have a wide range of antibacterial power, and have the same antibacterial activity as penicillin, especially for Gram-positive cocci, such as enterococci , Hemolytic streptococcus A group, pneumococcus and staphylococcus are effective. The usual dose is 2-4 times a day for 10 to 14 consecutive days. For non-inpatients, taking 2 to 4 times a day may cause inconvenience or forget to take it; therefore, it is best to reduce the frequency of daily use. Especially for non-hospital patients, a solid sustained release formulation can reduce the frequency of administration. Sustained-release formulations are designed to keep the concentration of the drug in the blood relative to time in a stable state, so that patients taking 2-4 times a day can avoid the situation of overdose when taking the next tablet. It is known to use alginate gums to prepare controlled release tablets. A water-soluble alginate, such as sodium alginate, reacts with the calcium salt, which allows the alginate to be converted into a water-insoluble sodium alginate-calcium gum. The alginate gum can be changed by changing the molecular weight of alginate, the content of alginate, the type of polyvalent cations and cross-linking agents, and / or the content of cations in alginate-5-200536570 ( 2) Controlled release properties. U.S. Patent No. 4,8 4 2,8 66 discloses the use of sodium alginate and sodium alginate-calcium to prepare solid controlled release dosage forms. The above-mentioned patented technology cannot be applied to the formulations containing the main drug with very low water solubility. For example, the formulation made of carisin and alginate is too slow to dissolve and it has been used in live animal experiments. Bioavailability is not reproducible. For medicines with very low water solubility, alginate can be used as a matrix and organic acids can be added to make solid controlled release dosage forms. U.S. Patent No. 5,7 05,190 (which is equivalent to Republic of China Patent No. 429,154) discloses a controlled release dosage form containing water-soluble alginates, alginate complexes and organic carboxylic acids (which promote Dissociation of the active ingredient). An example of an active ingredient is karomycin, which is easily soluble in gastric juice, and easily soluble in the upper part of the small intestine (pH 5 · 0), where karomycin is most likely to be absorbed; It is not easy to dissolve in the lower part of the small intestine (pH 6 to 8), so in order to increase the solubility in this part, citric acid is used in the formula. In the oral pharmaceutical composition filed in U.S. Patent No. 5,70 5, 1 90, the weight ratio of sodium alginate to sodium alginate-calcium is about 16: 1 to 1: 1, and organic acids such as citric acid ) The molar ratio to the main drug is 1: 1. In U.S. Patent No. 5,7 05,190, a solid-state controlled release pharmaceutical composition includes sodium alginate, sodium alginate-calcium, and an organic carboxylic acid (e.g., citric acid). However, this formula does not address or reduce the side effects associated with gastrointestinal upset, including nausea, vomiting, and taste disorders. In order to overcome these problems, an improved controlled release formulation containing a poorly soluble main drug such as erythromycin has been developed, as described in U.S. Patent No. 6,010,718. These formulations contain pharmaceutically acceptable polymers -6-200536570 (3) polymers such as hydroxypropyl methylcellulose to improve the taste of fast release dosage forms and reduce gastrointestinal side effects. U.S. Patent No. 6 5 5 5 1,6 6] B 1 and U.S. Patent No. 6,010,718 are similar in content, but the former contains more results on the gastrointestinal side effects of the patient, and proves the continuity of taking karomycin Patients who release the formulation are significantly less likely to discontinue medication due to gastrointestinal side effects, and those patients have significantly less severe gastrointestinal side effects. As disclosed in U.S. Patent No. 5,705,190, Klaricid® XL (Abbott Laboratories Ltd., Queenbor ο υ gh 5 Kent, ME11 5EL, UK, Cairo Risomycin Continuous Release Tablets) contains 500 mg of Cairo Risomycin and other inactive ingredients such as: citric acid, sodium alginate, Sodium alginate-calcium, lactose, povidone, talc, stearic acid, magnesium stearate, hydroxypropyl methylcellulose, propylene glycol, titanium dioxide (E1711), sorbic acid, quinoline Yellow pigment (E 1 04) and so on. And this formula contains sodium alginate (water-soluble alginate), sodium alginate-calcium (water-insoluble alginate), and citric acid (organic carboxylic acid) are used to help dissolve cairolimin. The contents of sodium alginate and sodium alginate and calcium are very different, so it is difficult to mix them evenly. Although U.S. Patent No. 5,705,190 mentions that the ratio of sodium alginate to sodium alginate-calcium is 16: 1 to 1: 1, the actual weight ratio in Klaricid® XL tablets is 8: 1. If the content of both sodium alginate and sodium alginate-calcium is adjusted to be close to 'for example, the ratio is 2M or 1: 1', then the dissolution rate of karomycin is required for the study of the biological equality. Still a lot slower. 200536570 (4) [Summary of the invention] The main point of the present invention is to provide a controlled-release pharmaceutical formulation containing a poorly soluble main drug (such as a erythromycin derivative) for oral administration. In this formulation, only algae is required. Sodium is sufficient to replace the composition of sodium alginate and sodium alginate used in the prior art. Sodium alginate can be used to form a viscous gelatinous solution 'and although it is soluble in water, it is insoluble in acidic solutions having a pH of less than 3. So sodium alginate can protect the erythromycin derivative from rapid dissolution in gastric juice ', thus improving the stability of the erythromycin derivative. Using only sodium alginate can not only control the release of the erythromycin derivative, but also avoid the problem that the components are difficult to mix uniformly during the manufacturing process. In another aspect, the present invention provides a controlled-release pharmaceutical composition containing a poorly soluble main drug (e.g., an erythromycin derivative) for oral administration, and is coated with a film coating. Compared with the rapid-release pharmaceutical composition, the pharmaceutical composition of the present invention has a better taste, and the side effects of gastrointestinal discomfort are minimized. DETAILED DESCRIPTION OF THE INVENTION The present invention provides a once-a-day medication regimen by orally administering a solid-state controlled release pharmaceutical composition containing a poorly soluble main drug (such as a erythromycin derivative) to a patient in need of such treatment. The preferred dosage form is a lozenge. Erythromycin is a macrolide antibiotic. It is soluble in alcohol and common organic solvents, but only slightly soluble in water. It is extremely unstable at the -8-200536570 (5) end in solutions below pH 4. Erythromycin derivatives can include the following types: (1) acid addition salts on the bismethylamino group of desosamine, such as glucoheptonate, lactobionate And stearate (stearate); (2) esters on the OH group of desosamine, such as ethylcarbonate, ethylsuccinate, and propionate ( propionate); and (3) cairo risomycin and the like. The pharmaceutical composition of the present invention may contain other medicines known for use in combination with erythromycin derivatives as long as such combination therapy is necessary or advantageous; and these are related to the treatment of gastritis, ulcers, or gastroesophageal reflux disease ( GERD) other drugs may be anti-ulcer or anti-gastritis drugs, for example, selected from: compounds that inhibit gastric secretion, such as sulfamethoxazole, metronidazole, and cimetidine ( cimetidine), indapamide, atenolol, diazepam, omeprazole, ranitidine, sucralfate, etc .; Or antacids such as magnesium hydroxide, aluminum hydroxide, sodium carbonate, simethicone and so on. The content of these drugs in the pharmaceutical composition may range from 20% to 90% of the entire composition or the entire tablet. For Cairomycin, this content range may preferably be 40% to 80% by weight of the entire composition or the entire tablet. Although the present invention preferably uses sodium alginate, other cations, such as potassium ions, ammonium ions, and other alkaline metal ions, can also replace sodium ions 200536570 (6) to form water-soluble alginates. The content of water-soluble alginate can range from 10% to 40% of the weight of the entire composition or the entire tablet. The organic carboxylic acid required in the controlled-release formulation of the present invention is an acid sufficient to create a low ρΗ 値 microenvironment, that is, a microenvironment having a pH of less than 7 is formed near the hydrolyzed dosage form. The weight ratio of this main medicine to acid can range from 1: 1 to 6: 1, and the best ratio is 4: 1. The acid is preferably an aliphatic organic carboxylic acid having 3 to 20 carbon atoms, such as succinic acid, tartaric acid, malic acid, glutaric acid, maleic acid, glutamic acid, citric acid, mandelic acid, etc. And citric acid is the best. The sodium alginate in the controlled release formulation will react to alginic acid in the gastric juice of the gastrointestinal tract, and alginic acid is slightly soluble in water, and will form a film on the surface of the controlled release dosage form to control the release of the drug. This is because the membrane controls the diffusion of the drug. As a result, water-insoluble alginates, such as sodium-calcium alginate, are no longer required to be used to control the release of cairocin. Other ingredients that are non-primary ingredients in the controlled release formulation of the present invention include: pharmaceutically acceptable excipients, diluents, preservatives, lubricants, lubricants, and approved pigments. The dosage form of the present invention may also be coated on the outer layer with a substance not related to the control or modification of drug release. [Embodiment] Example 11 [1] Granulation of controlled-release medicinal tablets All the tablet formulations were prepared by a general manufacturing method as described below. Cairomycin, sodium alginate, lactose and stearic acid all pass through the No. 40 sieve-10- 200536570 (7) net to remove any large agglomerates, and these sieved substances are mixed in the mixer (S upermi X er) for 20 minutes, and then slowly add polyvinylpyrrolidone and citric acid solution to form suitable granules. These wet granules passed through a No. 16 screen and used 60. The hot air of C is dried until the particles have a moisture content of 5 to 7% as measured by a K a r 1 F i s h e r. These dried granules were passed through a No. 20 sieve and mixed with a lubricant on a V mixer for 2 minutes. 2.

This figure shows the dissolution of Klaricid® XL lozenges (ORI) and the cairolimin continuous release type lozenges of the present invention (PBF). From the graph, it can be seen from Figure 1 that the dissolution of the two at each time point is very close, except that the difference in dissolution at the eighteenth hour is 5.46% (that is, 8 1. 9 3 %-7 6.4 7% = 5.4 6%), the other points are less than 5%, so the two may be biologically equal to each other in clinical trials. In addition, the KUricid® XL lozenge and the cairolimin of the present invention lasted from 16 to 200536570 (13) lozenges at each time point for each lozenge, as shown in Tables III and IV. In the six tests of aricid ® XL lozenges, the relative standard deviation (RSD) at each time point was between 1.16% and 14.37%, and for the six tests of the karomycin sustained release tablet of the present invention The relative standard error (RSD) at each time point was between 0.92% and 10 · 49%. Therefore, the average relative standard errors of K1 arcid ® X L lozenges and the sustained-release Kailoride dosing lozenges of the present invention are 4.71% and 2.98%, respectively. This indicates that the dissolution patterns of the multiple karomycin sustained-release tablets of the present invention are similar to each other, and in contrast, the dissolution patterns of the multiple Klaricid® XL tablets are less similar to each other . This advantage is due to the use of sodium alginate in the present invention, in contrast to the use of a combination of sodium alginate and sodium alginate in Klaricid® XL lozenges, which are different in the manufacturing process of Klaricid® XL lozenges Alginate can cause more difficult mixing problems. Advantages of the present invention A. The present invention appears to be easier to operate and more cost effective compared to US Patent No. 5,705,190 which uses two different alginates to prepare a sustained release lozenge. reduce. B. The sodium alginate formulated in the controlled release formulation of the present invention will react to form alginic acid in the gastric juice of the gastrointestinal tract, and alginic acid is slightly soluble in water, and will form a film on the surface layer of the controlled release dosage form for controlling The release of the drug is because the film controls the diffusion of the drug. C. From the data in Table II, it can be seen that the dissolution rate of the tablets of the present invention is not significantly different from that of -17-200536570 (14) KI aric id® XL · tablets; however, Tables 111 and IV It can be seen that the inventors have a significantly smaller mean relative standard error (RSD), so it can be known that the dissolution patterns of the multiple cairolimin sustained-release tablets of the present invention are similar to each other, compared to It appears that the dissolution profiles of multiple Klaricid® XL lozenges are less similar to each other. [Brief description of the figure] FIG. 1 shows the dissolution profile of KUricid® XL (represented by ORI) and the karomycin sustained-release tablet of the present invention (represented by pBF) in a pH 5.0 buffer solution.
