Abstract

An improved mixed particle of entecavir for treating various hepatitides is proportionally prepared from entecavir, suspending aid, flavouring, pigment and adhesive through pulverizing, sieving and granulating.

Description

A kind of improved Entecavir mix suspension grain and preparation method thereof
Technical field
The present invention relates to a kind of medicine and preparation method thereof, particularly a kind of improved Entecavir mix suspension grain that is used for the treatment of various hepatitis and preparation method thereof.
Background technology
Chronic viral hepatitis B is a kind of serious disease that is caused by hepatitis B viruses (HBV), also be high incidence and high mortality in the world disease it.This virus can cause lifelong infection, hepatic fibrosis or sclerosis, hepatocarcinoma, liver failure and death.Estimate that according to the U.S. CDC U.S. has the infected HBV virus of 1,250,000 people approximately, have every year and die from hepatitis B more than 5000 people and infect relevant disease, also increase 100,000 cases in addition every year newly with HBV; Europe has 1,000,000-2,000,000 people to infect HBV every year approximately, 90,000 people is wherein arranged approximately by persistent infection, has 2.2 ten thousand people finally to die from liver cirrhosis or primary hepatocarcinoma approximately; The whole world has 3.5 hundred million hepatitis B virus carrierss approximately, mainly be distributed in Asia, Africa and area, Latin America, the annual primary hepatocarcinoma that has 1,000,000-2,000,000 people to die from hepatitis B or cause approximately by chronic viral hepatitis B, occupy the 9th of disease death reason: the chronic viral hepatitis B patient of 10%-30% can develop into liver cirrhosis through 10-30, and the patient of about 1%-5% can develop into hepatocarcinoma through 20-40; The male mother of HBsAg can make infections in infants HBV by vertical transmission, wherein becomes the positive carrier of chronic HBsAg more than 90%, thereby has a strong impact on follow-on health.Therefore, effectively treat chronic viral hepatitis B, to reduce the HBV infection rate be the task of top priority of global the world of medicine.
Anti-HBV is the main means of treatment chronic viral hepatitis B, i.e. blocking-up or suppress hepatitis B viruses (HBV) duplicating in vivo lastingly, thereby alleviate or stop liver inflammation, necrosis and fibrosis lesion, stop pathological changes to lose compensatory, liver cirrhosis, liver failure and hepatocarcinoma development to liver function.The active drug of treatment chronic viral hepatitis B commonly used has interferon injection, oral antiviral drugs lamivudine and lamivudine and other antiviral drugs such as kurarinone etc.
Entecavir (entecavi :) is the light carbon deoxidation of an epoxy bird battalion, is a kind of deoxidation bird nuclear battalion analog that can effectively suppress hepatitis B virus duplication, has stronger anti-HBV effect.The chemical name of Entecavir is a 2-amino-1,9-dihydro-9[(15,3R, 4S foretell the light base-3-of 4-(through methyl rises 2-methylene Pentamethylene. fore-telling 6H-he cry of certain animals-6-ketone, monohydrate. molecular formula is C12H15NSO3.HZO, and molecular weight 295.3. structural formula is as follows:
Figure A20071002668400071
Entecavir is as the general analog of nuclear that suppresses hbv replication, and its indication is the adult chronic viral hepatitis B active stage patient of the HBVDNA positive and HBeAg positive or negative and the patient invalid to lamivudine therapy.Recommended dose is: 1 of Zhi Liao the hepatitis B patient patient of general analogue treatment (do not accept nuclear) every day first, every 0.5mg; The drug-fast patient of lamivudine therapy (lamivudine therapy inefficacy patient) is 1 of every day, every 1.0mg.The patient is all good to the toleration of two kinds of therapeutic doses of Entecavir.Use Entecavir and treat the patient that the virus mutation that causes only occurs in the strain of infection lamivudine resistance mutated viruses, and aberration rate low (5.8%).
The pharmacokinetics evaluation experimental shows that this medicine oral absorption is good, and peak plasma concentration and AUC value all are dose dependent to be increased.Blood drug level is two index decreased, and average t1/2 is 55h, and the thing of taking medicine is eliminated from urine with the prototype medicament forms more than 50%.Tubular secretion is the main path of eliminating, and renal clearance is in the scope of 300-600ml/min.Entecavir health adult in, pharmacokinetics index between the severe hepatic injury patient is similar.In, severe liver injury patient need not to adjust dosage when using Entecavir.
Mix suspension grain is a kind of quick-effective preparation that development in recent years is got up, because its distinctive advantage more and more is subjected to people's attention.
Mix suspension grain (chewable tablets) definition: can even suspendible in adding entry.Normal sucrose, Herba Menthae, the flavorants etc. of adding are suitable for child administration to adjust taste, make mix suspension grain for the medicine of disintegrate difficulty and can help absorbing.Specification requirement: 1. mouthfeel, epigranular are good; 2. loss on drying must not surpass 2.0% 3. the settling volume ratio should be not less than 0.90 4. other should meet general rule requirement under the granule item.
Since mix suspension grain require water-soluble back suspendible evenly, good mouthfeel, to the oral mucosa nonirritant.Therefore the selection to supplementary product kind and performance thereof is the key of preparation mix suspension grain.
At present, it is rapid that extensive patients presses for a kind of absorption, can effectively improve the bioavailability and the blood drug level of Entecavir, improves the Entecavir mix suspension grain of Entecavir off-odor, taking convenience, few side effects simultaneously.The present invention has realized this purpose.
Summary of the invention
The inventor finds unexpectedly, if with the following technical scheme of the present invention, can make absorb fast, bioavailability is high, taking convenience, intestinal are residual less, few side effects and the good Entecavir mix suspension grain of mouthfeel.This purpose also of the present invention just.
Improvement Entecavir mix suspension grain of the present invention is made up of the effective amount of actives Entecavir and the adjuvant that pharmaceutically can prepare mix suspension grain.Adjuvant is any pharmaceutically acceptable auxiliaries that is fit to make mix suspension grain, and they can comprise suspending agent, correctives, odor mask, coloring agent etc.
