Description
Technical field
The invention belongs to medical technical field, be specifically related to a kind of Compound glucosamine sulfate dispersible tablet formulation and its preparation method that is used for the treatment of osteoarthritis.
Background technology
Osteoarthritis (Osteoarthritis, OA) be a kind of degenerative joint disease that incidence rate obviously increases with age growth, claim proliferative arthritis, degenerative osteoarthritis or osteoarthritis again, it is modal joint disease, also be the common cause that causes the middle-aged and elderly people arthralgia, have a strong impact on the quality of life of middle-aged and elderly people.
Because aged tendency of population in the prolongation of human average life and the world wide, medical care problem that countries in the world are relevant with OA and medical expense also sharply increase, and the social productive forces loss and the extra financial burden that are brought because of function and labour force's forfeiture also sharply increase thereupon.Estimate that according to WHO in the present global population, 10% medical care problem comes from OA.
The sickness rate of OA is higher.According to China's preliminary survey OA incidence rate is 3%, i.e. 3,600 ten thousand patients are the same substantially with U.S. incidence rate.Show that according to another Epidemiological study China OA prevalence is about 10%, the old people OA prevalence more than 60 years old is up to 50%, and along with the increase OA prevalence straight line at age rises.The ranks of world aging country are gone in China's stride, and population surpasses 100,000,000 more than 60 years old, estimate that OA patient is about 50,000,000.Estimate that following maximum OA patient crowd will be in China.
In a word, OA increases sharply to the mankind's threat, and effectively preventing and treating OA becomes one of key of improving people quality of life, also is an important problem of orthopedics circle.
The medicine of treatment OA is divided into nonspecific drug and specific drug two big classes at present.Nonspecific drug mainly comprises oral non-opium analgesic, NSAID (non-steroidal anti-inflammatory drug) (NSAID) and intraarticular injection glucocorticoid etc.Light for clinical inflammation performance, only, consider earlier regularly or oral in case of necessity analgesics based on the patient of pain, external first-selected acetaminophen, analgesic effect is obvious, but the report of pair liver, renal damage is arranged after long-term the extensive application; For the heavier patient of the inflammation in joint, NSAID is still traditional first-selected medication, common drug have diclofenac, ibuprofen, naproxen and former times the dry goods medicine, but untoward reaction is more, especially the gastrointestinal reaction has limited its prolonged application.If this class drug main antiinflammatory, pain relieving, i.e. doing well,improving medicine, but can not mitigate the disease, if improper use, even increase the weight of the state of an illness, as the intraarticular injection glucocorticoid, can further destroy cartilage, cause articular degeneration.
Specific drug is that exploitation in nearest about 10 years is used for the treatment of the medicine of OA, also claims to do slowly the pathological process that medication, this class medicine can stop or slow down OA, suppresses to cause the correlation factor of tissue injury and articular cartilage degeneration.Slowly act on medicated bag and draw together glucosamine sulfate, chondroitin sulfate, diacerein and intraarticular injection hyaluronic acid etc.Improve medicine though also be classified as the state of an illness at present without any medicine; but many effects of pointing out this medicine to have simultaneously probably to improve OA patient symptom and protection articular cartilage about the glucosamine sulfate clinical test results are the ideal medicament of treatment osteoarthritis.
Glucosamine is a kind of natural saccharide that derives from chitin; be the main component in the cartilage matrix, by changing its side-chain structure, easilier in articular cartilage combine with water; the maintenance articular cavity lubricates the effect with compensator or trimmer pressure, and impaired chondrocyte is had the certain protection effect.The symptom development of synthetic glucosamine sulfate may command OA helps the reparation of cartilage.In the U.S., the compound recipe of glucosamine and chondroitin sulfate has very high safe reliability as food additive.Oral such medicine can reach therapeutic purposes.The patient of, pulmonary disease poor with blood circulation diseases, hepatic and renal function for some, diabetes has safety equally.
26 editions NF21 of American Pharmacopeia have recorded the complex tablet of glucosamine and chondroitin sulfate.Listing is that the preparation of main component is a lot of with glucosamine and chondroitin sulfate abroad, as MaxiLIFE (glucosamine sulfate 500mg/ chondroitin sulfate 400mg, Twinlab company, 30 on chip, Chondroitin Glucosamine Complex (glucosamine sulfate 250mg/ chondroitin sulfate 200mg, National Vitamin company, 60 are encapsulated).
