摘要:
Described here are devices, systems, and methods for treating conditions or diseases of the nose, ear, or throat with an expandable device having a drug coating. The expandable devices may be delivered to a body cavity in a low-profile configuration and expanded to contact surrounding tissue. The expandable devices may deliver or release the drug coating to the tissue. Multiple expansions of a single device may be employed during treatment. Various coating excipients and manufacturing parameters for the expandable devices may also be adjusted to enhance or slow transfer of the drug coating and/or release of the drug to the target tissue site. The drug transferred to the tissue may act as an in situ depot that enables maintenance of a therapeutic level of locally delivered drug for a desired time period after removal of the expandable devices.

Self-fixing semi-permeable porous artificial scab designed for protecting eroded or damaged surfaces. The invention applies to any living entity (including plants). The polymerized web of the scab is formed upon application to the damaged surface by a reaction catalysed by the action of enzymes released by the lysed cells. The growth of new, normal cells that can breathe freely without drying out is promoted under this protective surface. The loss of water, proteins and electrolytes is avoided, protection against infections is afforded and the use of gauzes or dressings that damage new skin when removed is replaced. The red aqueous mixture applied by brushing or spraying, which has thixotropic characteristics, was obtained by the physicochemical interaction in the container of the following compounds: azosulfamide of between 1 and 5g% + gentian violet of between 0.004 and 0.007 g% + dexamethasone of between 0.001 and 0.003 g% + panthenol of between 0.5 and 2g% + gentamicin of between 0.03 and 0.06g%.

Compositions which include a corticosteroid in combination with an additional compound active in treatment of an inflammatory disorder are provided.
摘要:
The invention relates to delivery devices and methods for providing more uniform delivery of agents such as drugs. In some embodiments, a delivery device is provided made of one or more implantable materials having predetermined agent-permeable and agent-impermeable regions and a reservoir containing one or more active agents, either alone or in an acceptable composition, as well as methods of administering one or more agents using such a device. Also provided are methods of equilibrating such devices, so that a steady state of agent delivery can be achieved at or soon after introduction of the device to its intended location of use. Methods of use of such devices to deliver an agent are also provided.

摘要:
Biocompatible intraocular implants include a steroid and an auxiliary agent, where the auxiliary agent is present in an amount sufficient to lessen the severity of at least one side effect compared to the use of an otherwise identical implant lacking said auxiliary agent. The steroid and the auxiliary agent may be present on the same intraocular implant or on different implants. The steroid and auxiliary agent may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. Or, the steroid may be associated with a polymeric coating having one or more openings effective to permit the steroid to be released into an external environment. The implants containing the steroid and an auxiliary agent may be placed in an eye to treat one or more ocular conditions while reducing the side effects otherwise accompanying steroid use.
