Naftin ® Gel, 1% contains the synthetic, broad-spectrum, antifungal agent naftifine hydrochloride. Naftin ® Gel, 1% is for topical use only.
(E)-N-Cinnamyl-N-methyl-1-naphthalenemethylamine hydrochloride. Naftifine hydrochloride has an empirical formula of C 21H 21N•HCl and a molecular weight of 323.86.
- CLINICAL PHARMACOLOGY
Naftifine Hydrochloride is a synthetic allylamine derivative. The following in vitro data are available but their clinical significance is unknown. Naftifine hydrochloride has been shown to exhibit fungicidal activity in vitro against a broad spectrum of organisms, including Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton tonsurans, Epidermophyton floccosum, Microsporum canis, Microsporum audouini, and microsporum gypseum, and fungistatic activity against Candida species, including Candida albicans. Naftin ® Gel, 1% has only been shown to be clinically effective against the disease entities listed in the INDICATIONS AND USAGE section.
Although the exact mechanism of action against fungi is not known, naftifine hydrochloride appears to interfere with sterol biosynthesis by inhibiting the enzyme squalene 2, 3-epoxidase. This inhibition of enzyme activity results in decreased amounts of sterols, especially ergosterol, and a corresponding accumulation of squalene in the cells.
In vitro and in vivo bioavailability studies have demonstrated that naftifine penetrates the stratum corneum in sufficient concentration to inhibit the growth of dermatophytes.
Following single topical applications of 3H- labeled naftifine gel 1% to the skin of healthy subjects, up to 4.2% of the applied dose was absorbed. Naftifine and/or its metabolites are excreted via the urine and feces with a half-life of approximately two to three days.
- INDICATIONS AND USAGE
Naftin ® Gel, 1% is indicated for the topical treatment of tinea pedis, tinea cruris, and tinea corporis caused by the organisms Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton tonsurans * 1, Epidermophyton floccosum * 1.
- Efficacy for this organism in this organ system was studied in fewer than 10 infections.

Naftin ® Gel, 1% is for topical use only and not for ophthalmic use.Close
Naftin ® Gel, 1%, is for external use only. If irritation or sensitivity develops with the use of Naftin ® Gel, 1%, treatment should be discontinued and appropriate therapy instituted.

Carcinogenesis, mutagenesis, impairment of fertility
Long-term studies to evaluate the carcinogenic potential of Naftin ® Gel, 1% have not been performed. In vitro and animal studies have not demonstrated any mutagenic effect or effect on fertility.
Pregnancy Category B
Reproduction studies have been performed in rats and rabbits (via oral administration) at doses 150 times or more than the topical human dose and have revealed no evidence of impaired fertility or harm to the fetus due to naftifine. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Naftin ® Gel,1 % is administered to a nursing woman.

- DOSAGE AND ADMINISTRATION
A sufficient quantity of Naftin ® Gel, 1% should be gently massaged into the affected and surrounding skin areas twice a day, in the morning and evening. The hands should be washed after application.
