The application discloses a stable
liver cancer embolism emulsion of raltitrexed
drug gel and a preparation method and application thereof, and belongs to the field of pharmaceutical preparations. The
emulsion is composed of
iodized oil embolism agent and raltitrexed
drug gel; the raltitrexed
drug gel is a
nanofiber network hydrogel formed by self-
assembly of raltitrexed molecules in an aqueous phase through ultrasonic treatment, and simultaneously serves as an active pharmaceutical ingredient and an
emulsion stabilizer. The
iodized oil and the raltitrexed drug gel are physically mixed and injected through a three-way valve to form a stable oil-in-water emulsion or a water-in-
oil emulsion, and any additional chemical surfactant or cosolvent is not needed. The emulsion has excellent
physical stability, and can effectively solve the problems of easy aggregation and
sedimentation of a traditional
iodized oil emulsion and increased
systemic toxicity caused by drug burst release. The emulsion has good
embolism effect and
drug release behavior, can significantly inhibit
tumor growth, and has a wide clinical transformation prospect.
