Stable, topical formulations useful for treating a nail fungal disease are disclosed. The compositions comprise an antifungal compound and at least one pharmaceutically acceptable excipient sufficient to form a gel. The antifungal compound is represented by the formula ##STR1## where R.sup.1, R.sup.2, and R.sup.3 are independently hydrogen or lower alkyl; X is --(CH.sub.2).sub.n -- in which n is 0, 1 or 2; Y is aryl or heteroaryl; and Ar is aryl or heteroaryl. The composition is applied to the afflicted nail for once a day until the fungal disease is cured.
An antibacterial composition for external application, particularly, a remedial formulation for external use containing fluconazole is disclosed. The formulation comprises a base material, 0.1-5.0 percent by weight of fluconazole and 1.0-40.0 percent by weight of any one compound selected from a group consisting of fatty acid, fatty alcohol, higher fatty acid ester and lower alcohol based on weight of the base material. The composition according to the present invention has various advantages of a favorable absorption into a system through the skin of a human body and delivery of active material into horny layer of the skin, a reduced skin stimulation and an excellent stability. Therefore, the composition is efficiently useable in a medical treatment application for dermatomycosis-related infectious diseases including tinea pedis, tinea corporis, tinea cruris, tinea versicolor and/or candidiasis and the like.
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.
A method of treatment of onychomychosis wherein a hydrogel is supersaturated with an antimycotic agent and supported on a backing. The assembly is placed over an infected nail for an extended period of time. The antimycotic agent diffuses through the nail to the underlying infection.
Methods and topical pharmaceutical formulations are provided for the treatment of nail fungus (onychomycosis). The invention involves a pharmacologically active antifungal agent, plus a pharmaceutically acceptable base in a formulation having a pH of 7.5 to about 13.0, preferably about 8.0 to 11.5, and most preferably about 8.5 to 10.5. These basic formulations permeate the nail and are effective in treating fungal infections of the nail and surrounding tissues.
