Description

Technical Field

[0001] This invention belongs to the field of drug preparation technology for preventing cerebral infarction, specifically a drug formulation and preparation method for preventing cerebral infarction and promoting rehabilitation. Background Technology

[0002] Cerebral infarction (also known as ischemic stroke) is a serious cardiovascular and cerebrovascular disease caused by impaired blood supply to the brain, leading to local brain tissue ischemia, hypoxia, and necrosis. It is characterized by high incidence, high disability rate, and high recurrence rate. With the increasing aging of the population and changes in lifestyle, the risk of cerebral infarction continues to rise, and it has become one of the major diseases threatening the health of middle-aged and elderly people.

[0003] Traditional Chinese medicine has accumulated rich experience in the prevention and treatment of cerebral infarction, emphasizing a holistic approach of "strengthening the body's resistance and eliminating pathogenic factors" and "treating both the root cause and the symptoms." Traditional Chinese medicine theory holds that "the kidneys govern bones and produce marrow, and the brain is the sea of ​​marrow," indicating a close relationship between declining brain function and deficiency of liver and kidney essence. Furthermore, "prolonged illness affecting the collaterals" and "internal obstruction of blood stasis" are important pathogenesis mechanisms in the development of cerebral infarction. Therefore, if nourishing the liver and kidneys, replenishing essence and marrow, can be organically combined with promoting blood circulation, removing blood stasis, and relieving pain, it is hoped that cerebral blood supply can be improved from the source, promoting the recovery of nerve function and reducing the risk of recurrence.

[0004] However, existing traditional Chinese medicine compound preparations generally suffer from problems such as complex ingredients, non-standard extraction processes, unstable content of active ingredients, and poor clarity, which affect clinical efficacy and patient compliance. In particular, for compound preparations containing animal-derived medicines (such as tortoise shell), if they are decocted with other herbal medicines, precipitation is easily caused by the interaction of proteins, colloids, and other components, which reduces efficacy or affects the quality of the preparation. Summary of the Invention

[0005] The purpose of this invention is to provide a drug formulation and preparation method for preventing cerebral infarction and promoting rehabilitation, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a drug formulation for preventing cerebral infarction and promoting rehabilitation and its preparation method, comprising the following raw materials in parts by weight: 10-15 parts of Astragalus complanatus, 10-15 parts of Cuscuta chinensis, 10-15 parts of tortoise shell, 10-12 parts of Paeonia lactiflora, 6-9 parts of Carthamus tinctorius, and 15-30 parts of Salvia miltiorrhiza.

[0007] As a further preferred embodiment of this technical solution, the following raw materials are included in parts by weight: 11 parts of Astragalus complanatus, 11 parts of Cuscuta chinensis, 11 parts of tortoise shell, 10 parts of Paeonia lactiflora, 6 parts of Carthamus tinctorius, and 17 parts of Salvia miltiorrhiza.

[0008] As a further preferred embodiment of this technical solution, the following steps are included:

[0009] S1: Clean and select the following herbs: Astragalus complanatus, Cuscuta chinensis, Paeonia lactiflora, Carthamus tinctorius, and Salvia miltiorrhiza, remove impurities, dry them for later use, and process the tortoise shell into small pieces before processing it separately.

[0010] S2: Decoction of tortoise shell alone: ​​Take tortoise shell and add 8 times the amount of water, bring to a boil over high heat, then simmer over low heat for 2 hours. Filter out the liquid. Add 6 times the amount of water to the dregs and decoct for 1 hour. Combine the two filtrates and concentrate to a relative density of about 1.10. At the same time, mix Astragalus complanatus, Cuscuta chinensis, Paeonia lactiflora, Carthamus tinctorius, and Salvia miltiorrhiza, add 10 times the amount of water and soak for 30 minutes. Decoction for 1.5 hours. Filter out the liquid. Add 8 times the amount of water to the dregs and decoct for 1 hour. Combine the two filtrates and concentrate to a relative density of about 1.15.

[0011] S3: Combine the tortoise shell concentrate with other medicinal material concentrates, stir evenly, and optionally add an appropriate amount of ethanol and let stand for 24 hours to remove some tannins and impurities, recover the ethanol, and obtain a clear medicinal solution.

[0012] S4: Spray dry the drug solution to obtain dry extract powder, add appropriate amount of dextrin, lactose and other excipients, mix evenly, make soft material with 70% ethanol, sieve and granulate, dry at below 60℃, granulate, sieve to obtain finished granules;

[0013] S5: Packaged in 5g bags, sealed with aluminum foil composite film, and subject to quality inspection in all aspects of the medicine;

[0014] As a further preferred embodiment of this technical solution: the concentration of ethanol added when the tortoise shell concentrate is combined with other medicinal material concentrates is 60%;

[0015] As a further preferred embodiment of this technical solution: the filter hole diameter for sieving and granulating the 70% ethanol-based soft material is 16 mesh, and the filter hole diameter range for sieving the dried granules is 18-60 mesh.

[0016] As a further preferred embodiment of this technical solution, the drug quality inspection aspects include appearance, moisture content, solubility, microbial limits, and content determination.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, by using Astragalus complanatus, Cuscuta chinensis, and tortoise shell to nourish the liver and kidneys, replenish essence and marrow, it conforms to the traditional Chinese medicine theory that "the kidneys govern bones and produce marrow, and the brain is the sea of ​​marrow," thus improving brain function decline from the source. At the same time, it is combined with Salvia miltiorrhiza, Paeonia lactiflora, and Carthamus tinctorius to promote blood circulation, remove blood stasis, unblock collaterals and relieve pain, effectively improving cerebral microcirculation, inhibiting platelet aggregation, and reducing blood viscosity. The two complement each other to achieve "strengthening the body's resistance and eliminating pathogens, treating both the symptoms and the root cause," which can be used for the prevention of cerebral infarction in high-risk groups and is also suitable for functional recovery during the rehabilitation period after cerebral infarction.

[0019] 2. In this invention, by using an extraction process that involves decocting tortoise shell separately from other medicinal materials and then combining the decoctions, the full dissolution of the gelatinous components in the tortoise shell is ensured, while avoiding precipitation or chemical reactions that may occur when decocting with other medicinal materials. The ethanol precipitation (60% ethanol) effectively removes impurities such as tannins and proteins, improving the clarity and stability of the preparation. Finally, the preparation is made into granules with good solubility, high bioavailability, and convenient for long-term use. Attached Figure Description
