    摘要: The present invention relates to improved methods for delivering bioadhesive, bioresorbable, anti-adhesion compositions. Antiadhesion compositions can be made of intermacromolecular complexes of carboxyl-containing polysaccharides, polyethers, polyacids, polyalkylene oxides, multivalent cations and/or polycations. The polymers are associated with each other, and are then used as fluids, gels or foams. By providing a product bag, the compositions can be delivered as gels or as sprays. By dissolving propellant gases in the compositions, the materials can be delivered as foams, which have decreased density, and therefore can adhere to surfaces that previously have been difficult to coat with antiadhesion gels. Delivery systems can also provide mechanisms for expelling more product, and for directing the flow of materials leaving the delivery system. Bioresorbable, bioadhesive, anti-adhesion, and/or hemostatic compositions are useful in surgery to prevent the formation and reformation of post-surgical adhesions. The biological and physical properties of such compositions can be varied as needed by carefully adjusting the pH and/or cation content of the polymer casting solutions, polyacid composition, the polyalkylene oxide composition, or by selecting the solids content of the composition. Antiadhesion compositions may also be used to lubricate tissues and/or medical instruments, and/or deliver drugs to the surgical site and release them locally.

    摘要: An ophthalmic fluid containing at least one triglyceride, diglyceride, or monoglyceride which is chemically similar or compatible with compounds found naturally in the lipid layer of the tear film of an ocular substrate. Preferably the glycerides are derived from a fatty acid containing at least one unsaturated bond in a cis-configuration in the fatty acid residue. The ophthalmic fluid is arranged in use to provide a protective film across a tear film of an ocular substrate. Furthermore, the ophthalmic fluid is also arranged in use to provide a protective film intermediate a lipid layer of the tear film of the ocular substrate and a contact lens.

    摘要: A method and preparation for the stimulation of tear secretion in a subject in need of such treatment is disclosed. The method comprises administering to the ocular surfaces of the subject a purinergic receptor agonist such as uridine 5null-triphosphate (UTP), dinucleotides, cytidine 5null-triphosphate (CTP), adenosine 5null-triphosphate (ATP), or their therapeutically useful analogs and derivatives, in an amount effective to stimulate tear fluid secretion and enhance drainage of the lacrimal system. Pharmaceutical formulations and methods of making the same are also disclosed. Methods of administering the same would include: topical administration via a liquid, gel, cream, or as part of a contact lens or selective release membrane; or systemic administration via nasal drops or spray, inhalation by nebulizer or other device, oral form (liquid or pill), injectable, intra-operative instillation or suppository form.

    摘要: Compositions comprising cationic polysaccharide polymers and anionic therapeutic agents which can have enhanced substantivity to mucosal surfaces are disclosed. These compositions are well suited, for example, for the delivery of anionic ophthalmic pharmaceuticals because they can provide clear solution in addition to substantivity.
