A nail lacquer effective for the treatment or prevention of fungal infections, such as, onychomycosis, includes fungicidally effective amount of ciclopirox, econazole, or other antifungal agent in a clear, stable, film-forming lacquer vehicle which includes a water-insoluble film-forming polymer; 2-n-nonyl-1,3-dioxolane or similar penetration enhancer; and volatile solvent. A plasticizer for the film-forming polymer which is also compatible with the other components may be included although the preferred penetration enhancers may also function as plasticizer. The composition, when applied to the nails provides a hard, clear, water-resistant film containing the antifungal agent. The film is resistant to multiple washings and is effective in the treatment of onychomycosis.

Antifungal nail lacquer and method using same

Topical alcoholic or aqueous alcoholic gels containing ibuprofen or other NSAIDs, such as, naproxen, in substantially neutral salt form, have enhanced penetration through skin and may provide rapid pain/inflammation relief by including in the formulation 2-n-nonyl-1,3-dioxolane or other hydrocarbyl derivative of 1,3-dioxolane or 1,3-dioxane or acetal, as skin penetration enhancing compound. The amount of propylene glycol may be varied to adjust the initial flux of the NSAID through the skin, especially for ibuprofen, naproxen, and ketorolac.

Non-steroidal antiinflammtory drug formulations for topical application

Topical alcoholic or aqueous alcoholic gels containing testosterone, progesterone, estradiol or other hormones have enhanced penetration through skin by including in the formulation 2-n-nonyl-1,3-dioxolane or other hydrocarbyl derivative of 1,3-dioxolane or 1,3-dioxane or acetal, as skin penetration enhancing compound.

Hormone replacement therapy drug formulations for topical application to

A composition for the topical transdermal administration to the penis is based on prostaglandin E.sub.1. The composition is non-irritating and effective for relieving erectile impotence or other penile erectile dysfunction. A penetration enhancing effective amount of a dioxolane, dioxane, or acetal skin penetration enhancing compound in a pharmaceutically acceptable aqueous alcoholic carrier is used to facilitate the penetration of the prostaglandin E.sub.1 active ingredient through the skin. Phentolamine or prazosin may be used in combination with prostaglandin E.sub.1.
