A nanobowl-supported drug-loaded liposome, a preparation method therefor, and an application thereof. The preparation method for the nanobowl-supported drug-loaded liposome comprises: incubating and ultrasonically treating a nanobowl and a liposome and then successfully encapsulating a drug by utilizing an ammonium sulfate active drug loading method to obtain the nanobowl-supported drug-loaded liposome. The nanobowl-supported drug-loaded liposome can resist the influence of plasma proteins and blood flow shearing forces on drug leakage, enhance the delivery of the drug at a tumor site, improve carrier stability, and improve an anti-tumor curative effect.

Disclosed are non-aqueous solid and liquid compositions comprising resiniferatoxin and a surfactant. The non-aqueous solid and liquid compositions may be used to prepare aqueous compositions that are used in the treatment of pain, specifically osteoarthritis-related joint pain. Moreover, also disclosed are kits containing the non-aqueous solid and liquid compositions and a diluent and methods of preparing the compositions. The non-aqueous solid and liquid compositions allow for longer storage and recovery of resiniferatoxin compared to resiniferatoxin alone prior to reconstitution with a diluent.
