摘要:
The invention contemplates a copolymer which is a graft or block copolymer useful to change wettability and surface characteristics of biological surfaces. Methods for use of these formulations and coatings to change wettability and sterically stabilize, and lubricate biological surfaces in a subject, for example, in the treatment of dry eye syndrome, and to prevent adherence of unwanted proteins, for example in the treatment of contact lens intolerance, are provided.

Bioadhesive nanoparticulate compositions, comprising active agent particles and one or more cationic surface stabilizers, are described. The cationic surface stabilizers prevent aggregation of the nanoparticles and increase bioadhesion of the nanoparticles to biological substrates, such as an insect, teeth, bone, nails, chitin, feathers, scales, mucous, skin, hair, plant tissue, etc. The particles may consist of pharmacologically active compounds (e.g., drug compounds for human or veterinary use), agricultural chemicals (pesticides, herbicides, fertilizers, and the like), cosmetic agents, consumer products (coloring agents, flavors, or fragrances), or other materials which function by interacting with biological substrates. In addition, the invention relates to methods of preparing and using such bioadhesive nanoparticulate compositions.

摘要:
Improved topical pharmaceutical compositions containing a pharmaceutically-active agent and the penetration enhancing agent 1-dodecylazacycloheptan-2-one are disclosed. This agent is used at selected levels in combination with certain C.sub.3 -C.sub.4 diols or a 1-substituted azacycloalkyl-2-one. This composition provides marked transepidermal and percutaneous delivery of the selected pharmaceutically-active agent. A method of treating certain pathologies and conditions responsive to the selected active, systemically or locally, is also disclosed.
摘要:
Diseases associated with the tissues in the posterior segment of the eye can be effectively treated by administering therapeutic agents transsclerally to those tissues. Compositions, devices, and methods for delivering therapeutic agents so that they cross the sclera and reach these tissues include injecting solutions or suspensions adjacent to or within the sclera and implanting solid structures containing the therapeutic agent adjacent to or within the sclera. These methods may be used for administering rapamycin or related compounds to treat choroidal neovascularization associated with age-related macular degeneration.

摘要:
A topical composition for treating nail fungal infections that utilizes an acidic antifungal agent with a molecular weight no greater than 170 Daltons in a formulation having a pH less than or equal to the pKa of the acidic antifungal agent plus one. Possible antifungal agents include omadine, octanoic acid, sorbic acid, hexanoic acid, and benzoic acid. The antifungal agent can be combined with a delivery system such as a lacquer, a gel, a patch, or a hydrating system. A second therapeutic agent such as a 5-fluorocystine or terbinafine can be included.
