Abstract
The present invention relates to a medicine composition of brain-protecting agent. Its main pharmacological active component is edaravone, and the preparation method of said medicine composition includes the following steps: mixing the edaravone with different pharmacologic permissible alkaline substance to make them into a clear solution, freeze-drying to make it into dreeze-dried powder injection. Said invented medicine composition dosage form is of freeze-dried powder injection, and is favorable for storage and transportation.
Description
Technical field the present invention relates to a kind of novel pharmaceutical formulation of cerebral protective agent, is specifically related to Edaravone lyophilized injectable powder and preparation method thereof.
The chemistry of technical background Edaravone (edaravone) is by name: 3-methyl isophthalic acid-phenyl-2-pyrazolin-5-one, and chemical structural formula is as follows:
Edaravone Injection (the trade name: Radicut that Mitsubishi Denki K.K.'s development of Japan is only arranged at present in the world
) listing, China does not still have this launch so far.Japan's listing product is the 20ml liquid drugs injection, and every injection contains the 30mg Edaravone, is the achromatism and clarity injection.Because dissolubility is very little in the Edaravone aqueous solution, in the process for preparation of water type injection, be difficult to reach effective drug level in the aqueous solution of small size, thereby the 30mg Edaravone need be with the water dissolution of 20ml nearly, water consumption is about 670 times of medication amount.And need under heated condition, carry out at the preparation and the sterilization process of injection, make the Edaravone degraded easily and produce more objectionable impurities.
Summary of the invention shows by our lot of experiments, adds the alkaline matter that pharmacology allows and can significantly improve the dissolubility of Edaravone in aqueous solution, thereby make the concentration of Edaravone can reach the drug level of clinical needs.Because Edaravone is in aqueous solution, stability variation relatively in hot water particularly, so, we by cryodesiccated method in order to the stability of raising Edaravone preparation in preparation process.
The purpose of this invention is to provide a kind of steady quality, transportation and preserve Edaravone lyophilized injectable powder more easily.
Edaravone pharmaceutical composition of the present invention mainly contains the alkaline matter of Edaravone and pharmacology permission, and wherein the amount of alkaline matter can make the Edaravone dissolving reach clinical desired drug level.
Alkaline matter used in the present invention can be a kind of organic base or inorganic base or with the mixture of basic amino acid, wherein organic base is preferably Tris; Inorganic base is preferably sodium hydroxide, potassium hydroxide, sodium carbonate, potassium carbonate; Basic amino acid is preferably: arginine, lysine, ornithine.
In the Edaravone freeze-dried powder of the present invention, caffolding agent (excipient) be can also contain, mannitol, sodium chloride are preferably.
In the Edaravone freeze-dried powder of the present invention, can also contain antioxidant and antioxygen synergist, be preferably: sodium thiosulfate, sodium sulfite, sodium pyrosulfite, sodium sulfite, vitamin C, disodiumedetate and nitrogen.
Edaravone freeze-dried powder of the present invention is to realize by following process: under cleaning condition, the Edaravone fine powder is suspended in the water for injection, add the alkaline matter that pharmacology allows, after stirring makes medicine dissolution, add other additives dissolving, decolouring, aseptic filtration, this pyrogen-free clear and bright filtrate is sub-packed in the aseptic cillin bottle, presses the freeze-dry process lyophilizing and promptly get product.
The clinical using method of Edaravone freeze-dried powder of the present invention is: the Edaravone lyophilized injectable powder is dissolved in 0.9% sodium chloride solution intravenous drip.
Edaravone lyophilized injectable powder of the present invention is owing to be the injection preparation of solid forms, and steady quality helps storing and transportation.
Some following concrete examples further describe the preparation process of Edaravone lyophilized injectable powder of the present invention, but are not limited to following examples.
