Efinaconazole is a triazole compound, with antifungal activity. Upon administration, efinaconazole targets, binds to and inhibits 14-alpha-demethylase, a cytochrome P450-dependent enzyme. Inhibition of 14-alpha-demethylase prevents the conversion of lanosterol to ergosterol, an important component of the fungal cell wall. Inhibition of ergosterol synthesis changes the fungal cell membrane composition and integrity, alters membrane permeability and eventually leads to fungal cell lysis.
Efinaconazole is an Azole Antifungal.

Jublia (efinaconazole) topical solution, 10% is an azole antifungal indicated for the topical treatment of onychomycosis of the toenail(s) due to Trichophyton rubrum and Trichophyton mentagrophytes. /Included in US product label/

NIH; DailyMed. Current Medication Information for Jublia (Efinaconazole) Solution (Updated: May 2016). Available from, as of July 5, 2016: https://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?setid=922d4d25-c530-11e1-9b21-0800200c9a66


We sought to evaluate the efficacy of efinaconazole topical solution, 10%, in patients with onychomycosis and coexisting tinea pedis. We analyzed 1,655 patients, aged 18 to 70 years, randomized (3:1) to receive efinaconazole topical solution, 10%, or vehicle from two identical multicenter, double-blind, vehicle-controlled 48-week studies evaluating safety and efficacy. The primary end point was complete cure rate (0% clinical involvement of the target toenail and negative potassium hydroxide examination and fungal culture findings) at week 52. Three groups were compared: patients with onychomycosis and coexisting interdigital tinea pedis on-study (treated or left untreated) and those with no coexisting tinea pedis. Treatment with efinaconazole topical solution, 10%, was significantly more effective than vehicle use irrespective of the coexistence of tinea pedis or its treatment. Overall, 352 patients with onychomycosis (21.3%) had coexisting interdigital tinea pedis, with 215 of these patients (61.1%) receiving investigator-approved topical antifungal agents for their tinea pedis in addition to their randomized onychomycosis treatment. At week 52, efinaconazole complete cure rates of 29.4% were reported in patients with onychomycosis when coexisting tinea pedis was treated compared with 16.1% when coexisting tinea pedis was not treated. Both cure rates were significant compared with vehicle (p = 0.003 and 0.045, respectively), and in the latter subgroup, no patients treated with vehicle achieved a complete cure. Treatment of coexisting tinea pedis in patients with onychomycosis enhances the efficacy of once-daily topical treatment with efinaconazole topical solution, 10%.

PMID:26429609 Markinson B, Caldwell B; J Am Podiatr Med Assoc 105 (5): 407-11 (2015)


A number of comorbidities and risk factors complicate the successful management of onychomycosis. Underlying conditions and patient characteristics, such as tinea pedis, age, and obesity, contribute to risk, whereas comorbidities, such as diabetes and psoriasis, can increase susceptibility to the disease. There are limited data on treatment effectiveness in these patients. Here, the authors review post hoc analyses of efinaconazole topical solution, 10%, in mild-to-moderate onychomycosis and present new data in terms of age and obesity. The only post hoc analysis to report significant differences so far is gender, where female patients do much better; however, the reasons are unclear. The authors report significant differences in terms of efficacy in obese patients who do not respond as well as those with normal body mass index (p=0.05) and in patients who have their co-existing tinea pedis treated compared to those in whom co-existing tinea pedis was not treated (p=0.025). Although there is a trend to reduced efficacy in older patients and those with co-existing diabetes, differences were not significant. More research is needed in onychomycosis patients with these important risk factors and comorbidities to fully evaluate the treatment challenges and possible solutions.

Onychomycosis is a common fungal infection of the nail unit that results in discoloration, subungual debris, thickening, onycholysis, and often pain and impairment of mobility. Dermatophytomas are characterized by a thick fungal mass within and under the nail plate and are especially resistant to treatment. Here we report a case of a patient with a dermatophytoma who had failed oral terbinafine but was successfully treated with efinaconazole 10% topical solution.

5.5 Absorption, Distribution and Excretion

Administration of Jublia by the topical route leads to low systemic efinaconazole concentrations. Systemic absorption of efinaconazole in 18 patients with severe onychomycosis was determined after application of Jublia once daily for 28 days to patients' 10 toenails and adjacent skin. The concentration of efinaconazole in plasma was determined at multiple time points over the course of 24-hour periods on days 1, 14, and 28. Efinaconazole mean plasma Cmax on Day 28 was 0.67 ng/mL. The mean plasma concentration versus time profile was generally flat over the course of treatment. In onychomycosis patients, the steady state plasma concentration range was 0.1-1.5 ng/mL for efinaconazole and 0.2-7.5 ng/mL for H3 metabolite.

/MILK/ Efinaconazole and or its metabolites were excreted in milk from lactating rats. The radioactivity concentration in milk was higher than that in plasma concentration for 24 hours after the administration of 14C-efinaconazole to lactating rats. However, the elimination half-life of the milk radioactivity was about one half of that of the plasma radioactivity, suggesting that efinaconazole or its metabolites was not retained in milk.

Efinaconazole penetrates through nails in vitro after Jublia administration, suggesting drug penetrations to the site of fungal infection in the nail and the nail bed, though clinical relevance is unknown. The penetration of Jublia was evaluated in an in vitro investigation after daily application of radiolabelled efinaconazole (10%) to human nails for 28 days at 55.1 uL/sq cm. After 28 days, the cumulative radioactivity in the receptor fluid and in the nail plate, on a percent basis of total administered radioactivity, was 0.03% and 0.16% (3.11 mg eq/g), respectively. The flux rate was relatively constant from Days 18 to 28, mean 1.40 ug eq/sq cm/day, suggesting steady state attainment.

5.6 Metabolism/Metabolites

Efinaconazole is extensively metabolized. It is oxidatively metabolized, cleaved and conjugated to glucuronic acid. The studies have identified 5 metabolites (H1, H2, H3, H4 and H5) of efinaconazole. In rats and minipigs, H3 was the major efinaconazole plasma metabolite, and its levels usually equaled or exceeded those of parent drug. The in vitro and in vivo metabolite profiles in nonclinical species were similar to human with no unique human metabolite(s).

Jublia (efinaconazole) is extensively metabolized through oxidative/reductive processes, with the potential of additional metabolite glucuronidation. Analysis of human plasma confirmed that H3 is the only major efinaconazole metabolite.

Efinaconazole metabolites, but not parent drug, were excreted in the bile and urine of rats and dogs which suggests complete metabolism of efinaconazole prior to excretion. Most of the absorbed radioactivity was eliminated during the first 72 hours after dermal and SC dosing in urine and feces.

5.7 Biological Half-Life

29.9 hours in healthy patients.


In a ... study of healthy volunteers, the plasma half-life of Jublia at day 10 following repeat treatment applications repeated to all 10 toenails was 29.9 hours.

5.8 Mechanism of Action

Efinaconazole is an azole antifungal. Efinaconazole inhibits fungal lanosterol 14-demethylase involved in the biosynthesis of ergosterol, a constituent of fungal cell membranes.


Efinaconazole is a triazole antifungal agent. Efinaconazole inhibits fungal lanosterol 14alpha-demethylase involved in ergosterol biosynthesis. The accumulation of 14alpha-methyl sterols and subsequent loss of ergosterol in the fungi cell wall may be responsible for the fungistatic and fungicidal activity of efinaconazole. Efinaconazole is shown in vitro to be substantially adsorbed to keratin but keratin binding is weak. Efinaconazole's low keratin affinity is expected to result in increased availability of free drug to the nail infection site.
