A particulate, modified release barrier coated drug-cation exchange resin complex comprising a core composed of a drug complexed with a pharmaceutically acceptable ion-exchange resin is provided. Methods of making and products containing this coated complex are described.

In one aspect, compositions are described herein. A composition described herein comprises a nanoparticle, a therapeutic species, and a linker joining the nanoparticle to the therapeutic species. The linker joining the nanoparticle to the therapeutic species comprises a Diels-Alder cyclo-addition reaction product. Additionally, in some embodiments, the nanoparticle is a magnetic nanoparticle.

The present invention provides polymers, particles, and compositions thereof that selectively and efficiently deliver various therapeutic agents, such as metabolites, to a cell. The present invention further relates to methods relating to the said polymers, particles, and compositions for enhancing biological tissue growth (e.g. biological tissue regeneration in wound healing) in a subject. The present invention additionally provides kits that find use in the practice of the methods of the invention.

Provided are ultra fast-acting subcutaneously injectable insulin formulations as well as a stabilized subcutaneously injectable insulin and glucagon formulations, in addition to injection systems and methods of treatments and use thereof.

A method of producing embolic particles includes forming a master batch of embolic particles, wherein the master batch of particles includes a plurality of negatively charged loading sites. The method also includes modifying the master batch of particles to form an activated batch of particles by reacting the master patch of particles with a bridging agent. The activated batch of particles includes a plurality of activated loading sites configured to bond to a negatively charged drug.

A method of inducing cell death in a subject includes administering to the subject a plurality of cell targeted nanobubbles that are internalized by the target cell and insonating nanobubbles internalized into the target cell with ultrasound energy effective to promote inertial cavitation of the internalized nanobubbles and apoptosis and/or necrosis of the target cell.

Non-linear multiblock copolymer-drug conjugates for the treatment and prevention of diseases and disorders of the eye are provided. The polymer-drug conjugates can form nanoparticles, microparticles, and implants that are capable of effectively delivering therapeutic levels of one or more active agents for an extended period of time. Administration to the eye of an active agent in the form of a non-linear multiblock copolymer-drug conjugate produces decreased side effects when compared to administration of the active agent alone. Also provided are methods of treating intraocular neovascular diseases, such as wet age-related macular degeneration as well as diseases and disorders of the eye associated with inflammation, such as uveitis.

In one aspect, compositions are described herein. A composition described herein comprises a nanoparticle, a therapeutic species, and a linker joining the nanoparticle to the therapeutic species. The linker joining the nanoparticle to the therapeutic species comprises a Diels-Alder cyclo-addition reaction product. Additionally, in some embodiments, the nanoparticle is a magnetic nanoparticle.

The invention generally relates to compositions and methods for transporting substances across mucosal barriers. The invention also relates to methods of making and using such substances.

Described herein are polymeric particles configured for intravascular delivery of pharmaceutical agents, e.g., to a diseased site, and methods of forming and using same. Preparation of these polymer particles is also described.
