Description
Technical field
The invention belongs to field of pharmaceutical preparations, more particularly relate to a kind of stable pharmaceutical composition that contains the administrated by injection of active component silibinin and salt thereof.
Background technology
Hepatitis is meant the liver inflammation.It comprises the hepatitis that Different types of etiopathogenises is different.But viral hepatitis is the most common in the daily life, so people abbreviate viral hepatitis as hepatitis habitually.Viral hepatitis is that common clinically a kind of liver damage is main, the infectious disease of immune dysfunction.It has the sickness rate height, and the course of disease is long, and the patient's condition repeatability is strong, and the characteristics that hazardness is bigger if do not treat effectively and timely, very easily change hepatitis interstitialis chronica and hepatocarcinoma into.At present viral hepatitis is mainly divided five kinds of first type, B-mode, third type, fourth type and hepatitis Es, finds to have own type hepatitis and hepatitis G in recent years again.Wherein first type and hepatitis E have self limiting, generally can not transfer to chronicly, and minority can develop into liver cirrhosis.Chronic hepatitis B and primary hepatoma substantial connection arranged.Calculate that according to existing investigation there are 1.2 hundred million human hepatitis B virus in China, the chronic viral hepatitis B patient is about, and 3,000 ten thousand, 3,800 ten thousand people carry hepatitis C virus., almost be that national people ten have one only from the numeral of hepatitis B virus carriers.
Silibinin is insoluble in water very much, makes that water solublity increases behind the meglumine salt.The sheet that silibinin and salt thereof (Seeley guest amine) is arranged in the market, also have silibinin and the oral cavity disintegration tablet of salt and the patent of reporting (200410069355.2 and 02156856.1) of dispersible tablet in the document, disclose the preparation method (200410023873.0) of silibinin salt lyophilized preparation recently again.The inventor emphasizes to have used solubilizing agent in the claims, and pH value is 7-12 when emphasizing that freeze-dried powder adds equal-volume water.As everyone knows, the physiological PH value that human body tolerated in the preparation of administrated by injection is 4-9, is PH10-12 and the inventor emphasizes in example, and this certainly will cause the zest of human body, and this method is that physiology is unacceptable.Silibinin and salt thereof are unstable under alkali condition on the other hand, are easy to oxidation.So adding stabilizing agent is very important.The present invention has overcome the deficiency of above-mentioned patent, produces the ejection preparation of effective silibinin of stability and safety and salt thereof, satisfies clinical requirement.
Summary of the invention
The objective of the invention is overcoming the shortcoming and defect of above-mentioned prior art, provide and be fit to the injectable drug that clinical acute hepatopathy treatment requires, the present invention is an active component with silibinin and salt thereof, invented the stable pharmaceutical composition of drug administration by injection, especially intravenous administration has solved the demand in the treatment.
