After topical application to the skin of normal subjects, systemic absorption of econazole nitrate is extremely low. Although most of the applied drug remains on the skin surface, drug concentrations were found in the stratum corneum which, by far, exceeded the minimum inhibitory concentration for dermatophytes. Inhibitory concentrations were achieved in the epidermis and as deep as the middle region of the dermis. Less than 1% of the applied dose was recovered in the urine and feces.
Microbiology: Econazole nitrate has been shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section.
| Dermatophytes | Yeasts |
| Epidermophyton floccosum | Candida albicans |
| Microsporum audouini | Malassezia furfur |
| Microsporum canis | |
| Microsporum gypseum | |
| Trichophyton mentagrophytes | |
| Trichophyton rubrum | |
| Trichophyton tonsurans |
Econazole nitrate exhibits broad-spectrum antifungal activity against the following organisms in vitro, but the clinical significance of these data is unknown.
| Dermatophytes | Yeasts |
| Trichophyton verrucosum | Candida guillermondii |
| Candida parapsilosis | |
