The invention provides a dithioram nanoparticle, including dithioram and a stabilizer, which includes phospholipid material, vitamin E polyethylene glycol succinate, methoxy polyethylene glycol polycaprolactone, methoxy polyethylene glycol polylactide, poloxamer P188, sodium oleate, hydroxypropyl beta cyclodextrin, or a combination of phospholipid material and benzel. The hydrophilic part of the stabilizer in the dithioram nanoparticles constitutes a hydrophilic outer layer. The lipophilic part of the stabilizer forms a lipid-soluble core to encapsulate the component dithioram drugs, which ensures that the water-insoluble dithioram drugs can be evenly dispersed in the water phase in the form of nano-sized particles, solves the problems of insoluble and difficult administration, and protects the encapsulated drugs from being encapsulated. As for rapid degradation. With the disulfiram nanoparticles as the active ingredient, various dosage forms commonly used in clinic can be prepared by modern preparation technology, thus meeting various clinical needs, including cancer prevention and treatment.
