Puerarin derivatives powder injection and its production method

Abstract

The invention provides a puerarin derivant powder injection preparation, which is characterized in that each powder injection of the powder injection preparation contains 0.001g to 0.1g of active component of puerarin derivant; the pharmaceutic adjuvants of the injection are that: one or more of polysorbate 80, kollison K30, hydroxypropul beta cyclodextrin is selected as solubilizer; one of poloxamer 188 or mannite or the combination thereof is selected as addictive agent; and the weight ratio between the puerarin derivant and the solubilizer is 1: (6-16); the weight ratio between the puerarin derivant and the addictive agent is 1: (3-20). The invention also discloses a preparation method for the puerarin derivant powder injection preparation. The preparation technique makes use of solvent method to dissolve medicine and adjuvant into a same organic solvent, the solvent is removed through evaporation and the solid dispersion freeze-dried powder is finally obtained through freeze drying. The puerarin derivant powder injection preparation solves the problem of unstable quality of puerarin derivant liquid injection preparation and has advantages of good shaping, rapid dissolution, clearance, stability and convenient use, etc.

Problems solved by technology

Because the drug must be dissolved before it can be absorbed in the body, if tetraacetyl puerarin is prepared into quick-acting preparations such as dispersible tablets and dropping pills, the dosage will be large, which is difficult for patients to accept; if it is prepared into oral liquid, because tetraacetyl puerarin is in Poor stability in the solution, long-term storage, easy to degrade and precipitate out, resulting in the effectiveness and safety of the drug being affected
