Problems solved by technology

[0003] At present, cancer chemotherapy mainly adopts systemic administration, but there are some problems in this administration method: first, the drug is distributed to various organs and tissues of the whole body with the blood, which will bring systemic toxic and side effects; second, the drug that can be distributed to the tumor site Compared with the dosage, the amount is small, resulting in low local drug concentration and short duration of tumor lesions; third, patients cannot be given chemotherapy drugs immediately after tumor resection due to their physical condition, resulting in missing the best treatment period, etc.

Embodiment 1

[0042] Example 1 A preparation and application method of an antitumor agent containing hydrophobic chemotherapeutic drug nanoparticles and fibrin glue

[0043] 1. Use 2.5ml of physiological saline containing 3.414mg of paclitaxel nanoparticles (the particle size distribution is shown in figure 1 ) dissolving 100 mg of porcine-derived fibrinogen to form a uniformly dispersed porcine-derived fibrinogen solution containing paclitaxel nanoparticles.

[0044] 2. Dissolve the thrombin with 2.5ml calcium chloride solution, stir and oscillate slightly until it is completely dissolved, and obtain the thrombin solution.

[0045] 3. After the tumor resection is completed for the patient who needs to be treated, the above two solutions are sprayed around the wound of the patient's tumor resection site separately or at the same time.

Abstract

The invention belongs to the field of pharmaceutic preparations, and relates to an antineoplastic agent containing hydrophobic chemotherapeutic drug nano-particles and fibrin glue. The antineoplastic agent can be a pharmaceutic preparation composed of hydrophobic chemotherapeutic drug nano-particles and fibrin glue, and can also be an oncotherapy agent prepared from a hydrophobic chemotherapeutic drug nano-particle preparation and a fibrin glue preparation right before use. The antineoplastic agent can be used for local drug delivery after tumor excision, and can make local drug concentration stay at a high level for a long time.

[0002] Background of the invention [0003] At present, cancer chemotherapy mainly adopts systemic administration, but there are some problems in this administration method: first, the drug is distributed to various organs and tissues of the whole body with the blood, which will bring systemic toxic and side effects; second, the drug that can be distributed to the tumor site Compared with the dosage, the amount is very small, resulting in low local drug concentration and short duration of tumor lesions; third, patients cannot be given chemotherapy drugs immediately after tumor resection due to their physical condition, resulting in missing the best treatment period. Local administration of chemotherapeutic drugs can well solve the above problems. Local administration of chemoth...
