Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Luliconazole Cream, 1% is an azole antifungal [see Microbiology ( 12.4 )]. 12.2 Pharmacodynamics At therapeutic doses, Luliconazole Cream, 1% is not expected to prolong QTc to any clinically relevant extent. 12.3 Pharmacokinetics Luliconazole is the R enantiomer of a chiral molecule. The potential for interconversion between R and S enantiomers in humans has not been assessed. Information on the pharmacokinetics of luliconazole presented below refers to both R enantiomer and S enantiomer, if any, combined. Luliconazole is >99% protein bound in plasma. In a PK trial, 12 subjects with moderate to severe tinea pedis and 8 subjects with moderate to severe tinea cruris applied a mean daily amount of approximately 3.

Interactions
- 7 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 )] .
