Problems solved by technology

[0005] At present, the tirofiban hydrochloride injections listed at home and abroad all have the disadvantages of large volume and weight, inconvenient transportation and easy damage.
Moreover, the injections on the market are all liquid preparations, which need to undergo final high-temperature sterilization, which has a certain impact on the stability of the active ingredient. During storage, the active ingredient is not as stable as the solid form, and insoluble particles are easily produced in the solution. bring security risks
Freeze-dried powder injection can overcome the above defects, but so far there is no report on the listing of tirofiban hydrochloride freeze-dried powder injection
