DRUG INTERACTIONS An in vivo study in adult subjects with moderate to severe interdigital tinea pedis and tinea cruris showed that Luliconazole Cream, 1% is mostly a weak inhibitor of CYP2C19. In a separate trial in adolescent subjects with tinea cruris, in vivo blood levels of Luliconazole Cream, 1%, were seen to approach those levels sufficient to show moderate inhibition of CYP2C19 [see Clinical Pharmacology ( 12.3 )] .

ADVERSE REACTIONS The most common adverse reactions observed in clinical trials were application site reactions, which occurred in less than 1% of subjects.

In three Phase 3 clinical trials, 616 subjects were exposed to Luliconazole Cream, 1%: 305 with interdigital tinea pedis and 311 subjects with tinea cruris. Subjects with interdigital tinea pedis or tinea cruris applied Luliconazole Cream, 1% or vehicle cream once daily for 14 days or 7 days, respectively, to affected and adjacent areas. During clinical trials with Luliconazole Cream, 1%, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the Luliconazole and vehicle arms. Most adverse reactions were mild in severity. A post-approval clinical trial was conducted in 75 subjects age 2 to <18 years old with tinea corporis. The adverse reactions in the Luliconazole Cream, 1% treated population were similar to the vehicle treated population. 6.2 Postmarketing Experience The following adverse reactions have been identified during postmarketing use of luliconazole cream, 1%: contact dermatitis and cellulitis. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Mechanism of Action Luliconazole Cream, 1% is an azole antifungal [see Microbiology ( 12.4 )]. Mechanism of Action Luliconazole is an antifungal that belongs to the azole class. Although the exact mechanism of action against dermatophytes is unknown, luliconazole appears to inhibit ergosterol synthesis by inhibiting the enzyme lanosterol demethylase. Inhibition of this enzyme’s activity by azoles results in decreased amounts of ergosterol, a constituent of fungal cell membranes, and a corresponding accumulation of lanosterol.
