Abstract
The invention discloses a phloroglucinol sustained release tablet and a preparation method thereof. The phloroglucinol sustained release tablet is prepared by adopting a semi-dry wet granulation (auxiliary material granulation) process and comprises a therapeutically effective amount of phloroglucinol, a pharmaceutically acceptable framework material, an adhesive, a filler, a lubricant and the like. The content of phloroglucinol is 20.0% -50.0%, the content of insoluble framework material is 25.0% -56.0% and the content of hydrophilic gel framework material is 5.0% -55.0% by weight of the total weight of the preparation. The phloroglucinol provided by the invention has the advantages that the phloroglucinol can realize long-acting and stable release in different pH media from the integral effect, and the raw material medicines are basically not degraded in the preparation and storage processes, so that the quality is stable; simple process steps, low cost, convenient administration for patients and suitability for commercial production and popularization.
Description
Technical Field
The invention belongs to the field of pharmaceutical preparations, relates to a high-stability slow-release solid oral preparation, and in particular relates to a phloroglucinol slow-release tablet and a preparation method thereof.
Background
The slow release preparation refers to a preparation in which oral medicines are released slowly in a prescribed solvent at a non-constant speed as required, and the number of times of daily administration is reduced at least once or the interval between administrations is prolonged compared with the corresponding ordinary preparation. Compared with the sustained release preparation, the sustained release preparation can release the medicine more accurately and more uniformly, so that the blood concentration is more stable, and the toxic and side effects are reduced. For patients needing to take medicines for a long time, the slow release preparation can reduce the taking times and improve the compliance of the patients.
The phloroglucinol is a clinically common smooth muscle antispasmodic drug, can directly act on smooth muscle of gastrointestinal tract and genitourinary tract, relieve smooth muscle spasm, and is suitable for acute spasmodic pain, acute spasmodic urethra, bladder, renal colic, gynecological spasmodic pain and the like caused by digestive system and biliary tract dysfunction. Compared with other smooth muscle spasmolytics, the phloroglucinol has the characteristics of no anticholinergic effect, and can relieve smooth muscle spasticity without generating a series of anticholinergic side effects. The phloroglucinol can not cause symptoms such as hypotension, heart rate acceleration, arrhythmia and the like, has no influence on cardiovascular functions, and has wide application in the clinical spasmolytic and analgesic fields.
At present, the clinical common dosage forms of phloroglucinol are injection and orally disintegrating tablets, and the injection has the defects of short administration frequency, harsh use conditions and the like, so that the patient compliance is poor; the phloroglucinol orally disintegrating tablet has the advantages of rapid disintegration and dissolution, good taste, and the phloroglucinol preparation has the advantages of rapid onset of action, high safety and wide indication, but is biological in generalThe half-life period is short, the administration times are high (2 tablets are orally taken by an adult for 2-3 times a day), the pain can not be continuously relieved, and the existing dosage forms have the technical defect of being difficult to deal with the persistent spasmodic pain. The development of a once-a-day sustained release formulation not only improves patient compliance, but also reduces drug C in the blood max Reducing or avoiding side effects associated with dosage and increasing the efficacy of the drug by extending its effective concentration in the plasma has significant advantages. Therefore, the development of the phloroglucinol sustained release preparation for prolonging the acting time of the medicine is urgently needed in clinic.
The phloroglucinol has larger clinical dosage (320 mg-480mg of the adult daily) and better water solubility, and is difficult to maintain stable slow release by the prior conventional technology, thus seriously affecting the in vivo curative effect; in addition, the phloroglucinol raw material has the characteristics of poor stability and sensitivity to light and damp heat, and is easy to generate process impurities in the preparation process, thereby influencing the product quality.
At present, no literature report on a phloroglucinol sustained release preparation exists, and in the prior art (such as patent CN113616607A, CN 105560202B), when hydrophilic gel matrix materials such as hydroxypropyl methylcellulose, hydroxypropyl cellulose and a combination thereof are adopted to prepare a sustained release tablet, the dosage of the matrix materials is large, the early release speed of the prepared gel matrix sustained release tablet is relatively high, and burst release is easy to cause; in addition, the raw materials are easily soluble, the clinical administration specification is large, and when the hydrophilic gel framework material is used as the slow-release framework material, the release speed is difficult to control, the slow-release time is short, and the effect is poor. The existing slow release technology aims at the defect of the effective framework slow release material of large-scale high-water-solubility active ingredients, and development by research and development personnel is urgently needed.
Analyzing the above various techniques has certain defects, and a stable and long-acting phloroglucinol sustained release preparation cannot be prepared; therefore, the phloroglucinol sustained release tablet which is simple and controllable in preparation process, long-acting in release speed and stable is developed, and has remarkable advantages in pharmaceutical quality and market prospect. The invention adopts a combined framework material which takes an insoluble framework material as a main material and a hydrophilic gel framework material as an auxiliary material, and prepares the phloroglucinol sustained release tablet which can be stably stored and has no burst release and sustained release through a semi-dry wet granulation (auxiliary material granulation) process.
Disclosure of Invention
In view of the requirements of clinical medication and the defects of the prior art, the invention aims to provide the phloroglucinol sustained release tablet which has no burst release, slow release and high stability;

table 1 results of comparative tests before and after the acceleration test of examples and comparative examples
From the above results, it is clear that the phloroglucinol sustained release tablet prepared in examples 1 to 7 of the present invention can maintain stable release of phloroglucinol without abrupt release when the particle size distribution D10 of phloroglucinol is controlled to be 60 to 230 μm and the D90 of phloroglucinol is controlled to be 320 to 550 μm, and the dissolution end point is reached for about 12 hours; through accelerated test investigation, the appearance and the related substances are basically unchanged, and the dissolution curve can be kept stable and free from abrupt release. While the insoluble framework material or the hydrophilic gel framework material adopted in the comparative examples 1-3 is not in the required range, the particle size of the raw material phloroglucinol in the comparative examples 4-5 is not controlled in the required range, and the raw material phloroglucinol is dissolved out in a dissolution curve of 0 day, namely, the dissolution is too fast, the slow and stable release cannot be kept, and the dissolution end point is reached within 2 hours basically; after 6 months of acceleration, it was shown that (1) the relevant substances increased, especially for both comparative examples 3,4 out of limit; (2) the dissolution curve speed is increased, the release shows abrupt release behavior, and the dissolution is basically completed within 1-2h, and the end point is reached; in particular, comparative example 4 had a dissolution rate exceeding 85% at 1 hour. Comparative examples 6 to 7 use the formulation of the claims, but the preparation process of semi-dry wet granulation is not used, and the sustained release phloroglucinol tablet with long-time slow release and good stability cannot be prepared.
The result shows that the phloroglucinol sustained release tablet prepared by the invention has extremely outstanding sustained release effect, and remarkably prolongs the sustained release duration and clinical curative effect of the large-scale high-solubility drug phloroglucinol; the stability is good, and the generation of impurities can be effectively reduced; the dissolution performance is stable in the stability process, and the transportation and the preservation of the product are more facilitated.
