The invention relates to an anti-
cancer sustained release injection containing
epothilone derivative, consisting of sustained microspheres and menstruum. The sustained microspheres comprise anti-
cancer drugs selected from
taxane, alkylating agent and / or
plant alkaloid and the like, the
epothilone derivative and sustained release auxiliary material. The menstruum is a special menstruum containing suspending agent. The
epothilone derivative is selected from
epothilone B, epothilone D, iso-epothilone D, BMS-247550, azaepothilone B,
furan epothilone D or BMS-310705. The sustained release auxiliary material is selected from poly-dl-
lactide, the
glycolic acid copolymer of the poly-dl-
lactide, polyethyleneglycol, the polylactide
copolymer of the polyethyleneglycol, carboxyl terminated polylactide
copolymer,
fatty acid and
decanedioic acid copolymer, etc. The suspending agent is selected from
carboxymethyl cellulose and the like with the
viscosity of 100cp to 3000cp (under the temperature of 25 DEG C to 30 DEG C). The sustained release
microsphere can also be made into a sustained release
implant. The sustained release injection is injected or arranged in or around the tumour and can release
drug at partial position for 40 days approximately, therefore, the sustained release injection improves the local
drug concentration selectively and enhances the
treatment effect of non-operative treatments, such as radiotherapy,
chemotherapy and the like at the same time.
