Drug Details [pdf]

  • 1 INDICATIONS AND USAGE

    ERTACZO® (sertaconazole nitrate) cream, 2%, is indicated for the topical treatment of interdigital tinea pedis in immunocompetent patients 12 years of age and older, caused by Trichophyton rubrum, Trichophyton mentagrophytes, and Epidermophyton floccosum [see Clinical Studies (14)].

  • 2 DOSAGE AND ADMINISTRATION

    In the treatment of interdigital tinea pedis, ERTACZO cream, 2%, should be applied twice daily for 4 weeks. Sufficient amount of ERTACZO cream, 2%, should be applied to cover both the affected areas between the toes and the immediately surrounding healthy skin of patients with interdigital tinea pedis.

    Not for ophthalmic, oral, or intravaginal use.

  • 3 DOSAGE FORMS AND STRENGTHS

    Cream, 2%. Each gram of ERTACZO cream, 2%, contains 17.5 mg of sertaconazole (as sertaconazole nitrate, 20 mg) in a white cream base.

  • 4 CONTRAINDICATIONS

    None.

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Local Adverse Reactions

    If irritation develops, treatment should be discontinued and appropriate therapy instituted.

    Physicians should exercise caution when prescribing ERTACZO cream, 2%, to patients known to be sensitive to azole antifungals since cross-reactivity may occur.

  • 6 ADVERSE REACTIONS

    6.1 Clinical Trials Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug, and may not reflect the rates observed in practice.

    In clinical trials, cutaneous adverse events occurred in 7 of 297 (2%) subjects (2 of them severe) receiving ERTACZO cream, 2%, and in 7 of 291 (2%) subjects (2 of them severe) receiving vehicle. These reported cutaneous adverse events included contact dermatitis, dry skin, burning skin, and application site skin tenderness.

    In a dermal sensitization trial, 8 of 202 evaluable subjects tested with ERTACZO cream, 2%, and 4 of 202 evaluable subjects tested with vehicle exhibited a slight erythematous reaction in the challenge phase. There was no evidence of cumulative irritation or contact sensitization in a repeated insult patch test involving 202 healthy volunteers.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of ERTACZO cream, 2%. 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.

    In postmarketing surveillance for ERTACZO cream, 2%, the following were reported:

    Cutaneous adverse events: erythema, pruritus, vesiculation, desquamation, and hyperpigmentation.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Category C.

    There are no adequate and well-controlled studies conducted with ERTACZO cream, 2% in pregnant women. ERTACZO cream 2%, should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    Reproduction studies have not been performed with ERTACZO cream, 2%. Sertaconazole nitrate did not produce any evidence of maternal toxicity, embryotoxicity, or teratogenicity in rats and rabbits at an oral dose of 160 mg/kg/day (40 times [rats] and 80 times [rabbits] the maximum recommended human dose based on a body surface area comparison). A reduction in live birth indices and an increase in the number of still-born pups were seen at doses of 80 and 160 mg/kg/day sertaconazole nitrate in an oral peri- and postnatal development study in rats.

    8.3 Nursing Mothers

    It is not known if sertaconazole is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when prescribing ERTACZO cream, 2%, to a nursing woman.

    8.4 Pediatric Use

    The efficacy and safety of ERTACZO cream, 2%, have not been established in pediatric patients below the age of 12 years.

    8.5 Geriatric Use

    Clinical trials of ERTACZO cream, 2%, did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

  • 11 DESCRIPTION

    ERTACZO (sertaconazole nitrate) cream, 2%, is for topical application. It contains the azole antifungal, sertaconazole nitrate. Sertaconazole nitrate contains one asymmetric carbon atom and exists as a racemic mixture of equal amounts of R and S enantiomers.

    Sertaconazole nitrate is designated chemically as (±)-1-[2,4-dichloro-β-[(7-chlorobenzo-[b]thien-3-yl)methoxy]phenethyl]imidazole nitrate. It has a molecular weight of 500.8. The molecular formula is C20H15Cl3N2OS ∙ HNO3, and the structural formula is as follows:

    Chemical Structure

    Sertaconazole nitrate is a white or almost white powder. It is practically insoluble in water, soluble in methanol, and sparingly soluble in alcohol and in methylene chloride. Each gram of ERTACZO cream, 2%, contains 17.5 mg of sertaconazole (as sertaconazole nitrate, 20 mg) in a white cream base of ethylene glycol, glyceryl isostearate, glycolized saturated glycerides, light mineral oil, methylparaben, polyethylene glycol palmitostearate, polyoxyethylened saturated glycerides, purified water, and sorbic acid.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    ERTACZO cream, 2% is an azole antifungal [see Clinical Pharmacology (12.4)].

    12.3 Pharmacokinetics

    In a multiple-dose pharmacokinetic trial that included 5 male subjects with interdigital tinea pedis (range of diseased area, 42 - 140 cm2; mean, 93 cm2), ERTACZO cream, 2%, was topically applied every 12 hours for a total of 13 doses to the diseased skin (0.5 g sertaconazole nitrate per 100 cm2). Sertaconazole concentrations in plasma measured by serial blood sampling for 72 hours after the thirteenth dose were below the limit of quantitation (2.5 ng/mL) of the analytical method used.

    12.4 Microbiology

    Mechanism of Action
    Sertaconazole, an azole antifungal agent, inhibits fungal cytochrome P-450-mediated 14 alpha-lanosterol demethylase enzyme. This enzyme functions to convert lanosterol to ergosterol. Ergosterol is a key component of fungal cell membranes and lack of this component leads to fungal cell injury by leakage of key constituents in the cytoplasm from the cell.

    Activity In Vitro and in Clinical Infections
    Sertaconazole nitrate has been shown to be active against isolates of the following microorganisms in clinical infections [see Indications and Usage (1)]:

    •   Trichophyton rubrum
    •   Trichophyton mentagrophytes
    •   Epidermophyton floccosum
  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    In a rat dermal carcinogenicity study, topical administration of sertaconazole nitrate cream for up to 102 weeks did not increase the number of neoplastic lesions compared to control animals, at sertaconazole nitrate doses of up to 800 mg/kg/day (approximately 200 times the maximum recommended human dose based on a body surface area comparison).

    No clastogenic potential was observed in a mouse micronucleus test. Sertaconazole nitrate was considered nonclastogenic in the in vivo mouse sister chromatid exchange assay. There was no evidence that sertaconazole nitrate induced unscheduled DNA synthesis in primary rat hepatocyte cultures.

    At oral doses up to 60 mg/kg/day (16 times the maximum recommended human dose based on a body surface area comparison), sertaconazole nitrate exhibited no toxicity or adverse effects on reproductive performance or fertility in male or female rats.

  • 14 CLINICAL STUDIES

    In two randomized, double-blind clinical trials, subjects 12 years and older with interdigital tinea pedis applied either ERTACZO cream, 2%, or vehicle, twice daily for 4 weeks. Subjects with moccasin-type (plantar) tinea pedis and/or onychomycosis were excluded from the trial. Two weeks after completion of therapy (6 weeks after beginning therapy), subjects were evaluated for signs and symptoms related to interdigital tinea pedis.

    Treatment outcomes are summarized in the table below.
