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.
