43results about How to "Sustained delivery" patented technology

The present invention relates to method of sustained-delivery of an active drug to a posterior part of an eye of a mammal to treat or prevent a disease or condition affecting said mammal, wherein said disease or condition can be treated or prevented by the action of said active drug upon said posterior part of the eye, comprising administering an effective amount of an ester prodrug of the active drug subconjunctivally or periocularly. Preferably, the active drug is more than about 10 times as active as the prodrug. Other aspects of this invention deal with the treatment of certain diseases by the periocular or subconjunctival delivery of an ester prodrug, and certain pharmaceutical products containing ester prodrugs for periocular or subconjunctival administration.

A polymeric hollow nanoshell or nanosphere for release of an agent is described, wherein the hollow nanosphere comprises at least one biodegradable polymer, characterised in that the polymer is cross-linked. The biodegradable mono-disperse nanospheres described are suitable for use as carriers of biomolecules, therapeutic agents and/or imaging agents.

The invention relates to compositions comprising acyl derivatives of cytidine and uridine. The invention also relates to methods of treating hepatopathies, diabetes, heart disease, cerebrovascular disorders, Parkinson's disease, infant respiratory distress syndrome and for enhancement of phospholipid biosynthesis comprising administering the acyl derivatives of the invention to an animal.

Prodrugs of Formula I, their uses, their intermediates, and their method of manufacture are described:

A method of treating brain injury involving intrathecally administering a composite powder comprising superparamagentic nanoparticle and a therapeutic agent compound, and then magnetically transporting the composite into an injured brain.

The invention relates to magnesium-polymer composites, methods for their preparation and applications for their use. The composites include a combination of magnesium particles and polymer matrix. The polymer can include, but is not limited to, poly(lactic co-glycolic) acid. In certain embodiments, the composites of the invention are particularly useful for forming medical devices for implantation into a body of a patient. In certain other embodiments, the magnesium-polymer composites are useful for wound healing compositions for administration to an exterior surface of a body of a patient.

The invention provides methods of treating and preventing loss of tissue vascularization that can occur, for example, upon aging.

Methods are described for producing non-immunogenic nanoparticles from protein sources by controlling the pH in a nanoprecipitation process. The nanoparticles that are produced by the disclosed methods range in diameter size from about 100 ran to about 400 nm, with a preferred diameter size of from approximately 100 nm to approximately 300 nm, thereby rendering them non-immunogenic. The invention further discloses methods for producing nanoconjugates that are suitable for a variety of therapeutic, diagnostic and other uses.

Methods for modulating the axonal outgrowth of central nervous system neurons are provided. Methods for stimulating the axonal outgrowth of central nervous system neurons following an injury (e.g., stroke, Traumatic Brain Injury, cerebral aneurism, spinal cord injury and the like) and methods for inhibiting the axonal outgrowth of central nervous system neurons are also provided. Finally, a packed formulation comprising a pharmaceutical composition comprising an inosine nucleoside and a pharmaceutically acceptable carrier packed with instructions for use of the pharmaceutical composition for treatment of a central nervous system disorder is provided.

The present invention provides to at least one novel human GLP-1 receptor agonist, or specified portion or variant, including isolated nucleic acids that encode at least one GLP-1 receptor agonist, or specified portion or variant, GLP-1 receptor agonist, or specified portion or variants, vectors, host cells, transgenic animals or plants, and methods of making and using thereof, including the use of long acting GLP-1 receptor agonists to improve insulin sensitivity or lipid profiles in obesity and related therapeutic and/or diagnostic compositions, methods and devices.

Disclosed are formulations for providing a steroid. Formulations include a mineral coated microparticles wherein a steroid is adsorbed to the mineral coating or incorporated within the mineral coating. Also disclosed are methods for sustained delivery of a steroid and methods for treating inflammation or pain using a formulation for providing sustained delivery of a steroid.
