The present invention relates to an emulsion composition for chemoembolization comprising a nanoparticle comprising a drug and a biocompatible polymer, a water-soluble contrast agent and a water-insoluble contrast agent, and a water-insoluble drug as well as an aqueous drug can be administered in a form of stable emulsion, and drugs are slowly released, thereby enhancing the effect of chemoembolization.

Pharmaceutical compositions comprising spray-dried oxalate decarboxylase crystals are disclosed. Methods to treat a disorder associated with elevated oxalate concentration using compositions comprising spray-dried oxalate decarboxylase crystals are also disclosed.

Methods of treating an eye for an ocular condition such as placing a composite depot comprising a xerogel with embedded degradable particles into an anterior chamber of an eye to deliver a therapeutic agent. The xerogel is a hydrogel after exposure to intraocular fluid and is degradable. The degradable particles comprise the therapeutic agent and hydrolytically degrade in the anterior chamber to provide a controlled release of the therapeutic agent into the eye. Materials and processes for making depots are provided as well as alternative methods of their use.

Sustained release formulations of NMDA antagonists containing encapsulated NMDA antagonist are described herein.

Provided herein are rehydratable powdered formulations of nanocarriers that can be used to encompass hydrophobic or hydrophilic cargo. The formulations can be used for medicinal, agricultural, and research applications. Methods of making the formulations are also provided.

The present disclosure generally provides complexes including a pharmaceutically active agent and a functionalized polymer, wherein the functionalized polymer includes repeat units, the repeat units including ionizable repeat units having at least one ionizable side group and/or ionizable end group, a plurality of the at least one ionizable groups forming non-covalent bonds with the pharmaceutically active agent. Polymers which may be used to form such complexes as well as methods of making and using the complexes and related compositions are also provided.

A dry granulation process using a twin-screw extruder for granulating a powder mixture which includes at least one active ingredient and at least one carrier. The process includes steps of kneading the powder mixture in the screw barrel of the twin-screw extruder at a barrel temperature below a melting point of the at least one active ingredient and a melting point or a glass transition temperature of the at least one carrier to provide a kneaded powder mixture, and extruding the kneaded powder mixture to form granules. Granules and tablets produced using the dry granulation process in the twin-screw extruder are also provided.

Cationic polymers having one or more anionic ligand end groups, including a new class of carboxylated branched poly(beta-amino ester)s that can self-assemble into nanoparticles for efficient intracellular delivery of different biomolecules, including a variety of proteins is disclosed.

This disclosure relates to crystalline forms of 3-acyl-buprenorphine derivatives and sustained release injectable pharmaceutical compositions for treatment of opioid dependence, pain or depression, including an aqueous suspension of crystalline 3-acyl-buprenoprhine, or a pharmaceutically acceptable salt thereof, wherein the composition does not include an organic solvent, a polylactide polymer, a polyglycolide polymer, or a copolymer of polylactide and polyglycolide. This disclosure also includes 3-acyl-buprenoprhine or a pharmaceutically acceptable salt thereof prepared in a controlled release matrix, including poly(lactide-co-glycolide), sucrose acetoisobutyrate, lecithin, diolein and a combination of two or more thereof.

A method for preparing a microsphere include steps of dissolving an active ingredient and a biodegradable polymer in an organic solvent to prepare a dispersed phase, dissolving a salt in water to prepare a continuous phase, mixing and stirring the dispersed phase and the continuous phase to form an emulsion, removing the organic solvent; and drying.
