Nanocells allow the sequential delivery of two different therapeutic agents with different modes of action or different pharmacokinetics. A nanocell is formed by encapsulating a nanocore with a first agent inside a lipid vesicle containing a second agent. The agent in the outer lipid compartment is released first and may exert its effect before the agent in the nanocore is released. The nanocell delivery system may be formulated in pharmaceutical composition for delivery to patients suffering from diseases such as cancer, inflammatory diseases such as asthma, autoimmune diseases such as rheumatoid arthritis, infectious diseases, and neurological diseases such as epilepsy. In treating cancer, a traditional antineoplastic agent is contained in the outer lipid vesicle of the nanocell, and an antiangiogenic agent is loaded into the nanocore. This arrangement allows the antineoplastic agent to be released first and delivered to the tumor before the tumor's blood supply is cut off by the antianiogenic agent.

Biodegradable neurotoxin implants and methods of making and using such implants are provided. Biodegradable neurotoxin implants include a neurotoxin, a biodegradable polymer component, and an acidity regulating component. The biodegradable polymer component is effective in controlling the release of the neurotoxin from the implant when the implant is located in a patient's body. The acidity regulating component is effective in maintaining a pH of the implant in a desired range that may be effective in stabilizing the neurotoxin as the implant biodegrades when the implant is located in a patient's body. In one embodiment, an implant includes a botulinum toxin, a biodegradable polymer, and either monomers from which a biodegradable polymer is derived or oligomers including monomeric units substantially identical to a monomer from which a biodegradable polymer is derived, or a combination of such monomers and oligomers. The oligomers and biodegradable polymer may be derived from a single type of monomer. The implants disclosed herein may be administered to a human or animal patient in which a therapeutic effect is desired for prolonged periods of time.

Systems and methods are disclosed for microscale pharmacokinetics. Various organs and their interactions with drug compounds can be simulated in vitro by use of microscale compartments that can be interconnected by microscale channels. Cells or cellular materials associated with the organs can be cultured in such compartments to allow interactions with drug compounds in one or more fluidic flows. Such fluidic systems can include, by way of examples, gastrointestinal flow, blood flow, bile flow, urinary flow, and brain fluid flow. Interactions between fluidic systems can be simulated by a microscale permeable member. In one example, blood-biliary interaction can be simulated by a microscale permeable material having hepatocytes bound to a permeable substrate via a binder.
