Definitions

  • the invention belongs to the technical field of medicine, relates to a nano-fat bundle preparation and a preparation method thereof, in particular to a irinotecan hydrochloride nano-lipid preparation and a preparation method thereof.
  • Irinotecan hydrochloride is a derivative of camptothecin.
  • Camptothecin is a five-membered alkaloid extracted from the Chinese native plant camptotheca acuminata in 1966, USA. Camptothecin has strong anticancer activity and a broad antitumor spectrum. Camptothecin can specifically bind to type I topoisomerase and inhibit DNA replication repair, gene recombination and transcription associated with it by inhibiting topoisomerase.
  • camptothecin has certain problems in its use as a drug. Its toxic side effects such as myelosuppression and hemorrhagic cystitis, as well as its poor water solubility, have largely limited its clinical application. Therefore, researchers have developed camptothecin derivatives with higher anticancer activity and lower toxicity, such as 10-hydroxycamptothecin, 7-ethyl-10-hydroxycamptothecin (SN-38). Among them, the hydrochloride salt of CPT-11 (ie irinotecan hydrochloride) not only has higher anticancer activity and low toxicity, but also has certain water solubility, which greatly improves its convenience in clinical application. Irinotecan hydrochloride was used as a prodrug and was metabolized to the active SN-38 after administration, showing its antitumor activity.
  • CPT-11 ie irinotecan hydrochloride
  • irinotecan hydrochloride Since the administration of irinotecan hydrochloride produces side effects such as bone marrow function inhibition and gastrointestinal disorders, its use is strictly limited.

  • Passive loading method An example of preparation by a conventional method in which a lipid bilayer membrane is stabilized (Passive loading method).
