Abstract: Compositions and methods are presented that provide substantially improved physical and pharmacological parameters for subungually administrable formulations. Most beneficially, the compositions presented herein have a viscosity and film-forming capacity that retain the liquid formulation in sufficient quantities and that help penetrate the polysaccharide matrix commonly associated with onychomycosis. In especially preferred aspects, the carrier is formulated to have a high concentration of the active pharmaceutically active agent (API), to allow migration of the formulation within the subungual space, and to reduce systemic absorption while promoting diffusion of the API into the nail plate at or above minimum inhibitory concentration into a larger treatment space.

Abstract: Methods for the subungual treatment of diseases or disorders of the nail unit including infections, especially fungal infections, and nail psoriasis involving the toenails and fingernails are described. The methods provide a technique for placement of a drug-containing composition subungually with reduced risk of hematoma formation and improved patient comfort.

Abstract: Described here are various compositions for the delivery active agents, e.g., antifungal agents. The compositions may be beneficial due to the particular release kinetics associated with them. Various locations and methods for placement of the compositions into the tissues of the nail unit, as well as tissues surrounding the nail unit are also described.

Abstract: Onychomycosis is a fungal infection of the nail bed and is difficult to treat topically because penetration of the nail plate is difficult, and systemic antifungal treatments are prone to side effects and drug interactions. The present invention treats onychomycosis by applying an antifungal composition to the nail bed directly using a solid, semi-solid, or flowable carrier. The carrier can be in the form of a semi-solid into which the user digs and scrapes the nail, a solid carrier can be inserted directly under the nail in contact with the nail bed, or a flowable composition can be injected in contact with the nail bed.

Abstract: The biodegradable drug delivery systems described here are formulated for implantation into the nail unit and its surrounding tissues for the treatment of various nail unit conditions. The systems include greater than 30% by weight of the active agent, and may be formulated as solutions, solids, semisolids, microparticles, or crystals. Methods related to the implantation and use of the biodegradable drug delivery systems for treating nail unit conditions are also described.
