Naftifine is an allylamine antifungal drug for the topical treatment of tinea pedis, tinea cruris, and tinea corporis (fungal infections). Its precise mechanism of action is unknown, but may involve selectively blocking sterol biosynthesis via inhibition of the squalene 2,3-epoxidase enzyme. The half-life is approximately 2–3 days. The metabolites are excreted in the urine and feces.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
