Description

LIQUID DOSAGE FORM FOR TOPICAL APPLICATION
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of priority from U.S. Provisional Application Serial No. 62/612,853, filed January 2, 2018, the contents of which are incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to novel topical compositions comprising at least one penetration enhancer that promotes permeation of pharmaceutically active agent through nail or skin.
BACKGROUND OF THE INVENTION
Onychomycosis is a fungal infection of nail that affects 10% of the general population.
The most common cause of Onychomycosis is dermatophyte, which probably account for more than 85% of all cases. Onychomycosis is difficult to treat and has a high recurrence rate.
Treatment for onychomycosis is commercially available in oral or topical dosage form, which involves terbinafine (Lamisin, itraconazole (Sopranoe), ciclopirox (Penlae), and amorolfine (Locery1 ). Lamisil , marketed by Novartis, is very effective against onychomycosis administrated systemically, however, oral administration is associated with side effects such as liver toxicity.
Topical therapy is an alternative to oral therapy to diminish the side effects. Topical application of medications on nails allows active agents to penetrate through nail plate, reach nail bed, and eventually enter the systemic circulation bypassing the first-pass metabolism.
Commercially available nail lacquer like Penlac and Loceryl have been developed for nail fungal infection, but the treatment times are relatively long and cure rate are relatively low either compared with oral administration. Probably, the poor drug penetration is the bottleneck of these products. The 1% Lamisil cream is for treating skin fungal infection instead, terbinafine, being an effective antifungal agent, is not available in topical dosage form yet. The unmet medical need urges the development of effective topical therapies for nail fungal infection.

The nail comprises the nail plate, the nail matrix, and the nail bed. The nail plate is the hard, thin, translucent, slight elastic structure sitting on the nail bed, composed of keratin. The nail plate is made of dead keratinized cells which is formed by the cell division of nail matrix.
The penetration of the drug through the nail plate, where the medication applies on, is the key determining the effectiveness of the topical therapy. The keratin binding affinity of drugs correlate to its penetration through the keratin matrix in nail plate. Low keratin binding efficiency contributes to increased permeability, which is a desirable physiochemical property of drugs as higher proportion of administrated drug can be targeted to the lower nail layer.
Many antifungal drugs are reported to bind strongly to keratin and thus developing formulations that dwindle the interactions between the drugs and keratin is necessary.
SUMMARY OF THE INVENTION
The present invention relates to novel liquid topical compositions comprising at least one penetration enhancer that promotes permeation of pharmaceutically active agent through nail or skin. In particular, the invention relates to pharmaceutical formulations of but not limited to terbinafine for treating onychomycosis.

DETAILED DESCRIPTION OF THE INVENTION
The detailed description is merely exemplary in nature and is not intended to limit application and uses. The following examples further illustrate the present invention without, however, limiting the scope of the invention thereto. Various changes and modifications can be made by those skilled in the art on the basis of the description of the invention, and such changes and modifications are also included in the present invention.
In one embodiment, the present invention provides a liquid topical composition comprising a matrix comprising an effective amount of a pharmaceutically active agent and one or more penetration enhancer having a combined hydrophilic- lipophilic balance of about
