(miconazole nitrate, zinc oxide, and white petrolatum) Structural Formula Illustration

The zinc oxide has an empirical formula of ZnO and a molecular weight of 81.39.

The white petrolatum, which is obtained from petroleum and is wholly or nearly decolorized, is a purified mixture of semisolid saturated hydrocarbons having the general chemical formula C_nH_2n+2. The hydrocarbons consist mainly of branched and unbranched chains. White petrolatum contains butylated hydroxytoluene (BHT) as stabilizer.

Each gram of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) contains 2.5 mg of miconazole nitrate USP, 150 mg of zinc oxide USP, and 813.5 mg of white petrolatum USP containing butylated hydroxytoluene, trihydroxystearin, and Chemoderm® 1001/B fragrance.¹

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is a smooth, uniform, white ointment.

Indications

INDICATIONS

Indication

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) Ointment is indicated for the adjunctive treatment of diaper dermatitis only when complicated by documented candidiasis (microscopic evidence of pseudohyphae and/or budding yeast), in immunocompetent pediatric patients 4 weeks and older. A positive fungal culture for Candida albicans is not adequate evidence of candidal infection since colonization with C. albicans can result in a positive culture. The presence of candidal infection should be established by microscopic evaluation prior to initiating treatment.

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) should be used as part of a treatment regimen that includes measures directed at the underlying diaper dermatitis, including gentle cleansing of the diaper area and frequent diaper changes.

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) should not be used as a substitute for frequent diaper changes. VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) should not be used to prevent the occurrence of diaper dermatitis, since preventative use may result in the development of drug resistance.

Limitations of Use

The safety and efficacy of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) have not been demonstrated in immunocompromised patients, or in infants less than 4 weeks of age (premature or term).

The safety and efficacy of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) have not been evaluated in incontinent adult patients.

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) should not be used to prevent the occurrence of diaper dermatitis, such as in an adult institutional setting, since preventative use may result in the development of drug resistance.

Side Effects & Drug Interactions

SIDE EFFECTS

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rate 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 clinical practice.

A total of 835 infants and young children were evaluated in the clinical development program. Of 418 subjects in the VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) group, 58 (14%) reported one or more adverse events. Of 417 subjects in the zinc oxide/white petrolatum control group, 85 (20%) reported one or more adverse events. Adverse events that occurred at a rate of ≥ 1% for subjects who were treated with VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) were approximately the same in type and frequency as for subjects who were treated with zinc oxide/white petrolatum ointment.

Post-marketing Experience

The following adverse reactions have been identified during post approval use of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) .

Gastrointestinal Disorders: vomiting

General Disorders and Administration site Conditions: burning sensation, condition aggravated, inflammation, pain

Injury, Poisoning and Procedural Complications: accidental exposure

Skin and Subcutaneous Tissue Disorders: blister, dermatitis contact, diaper dermatitis, dry skin, erythema, pruritus, rash, skin exfoliation

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.

DRUG INTERACTIONS

Drug-drug interaction studies were not conducted. Women who take a warfarin anticoagulant and use a miconazole intravaginal cream or suppository may be at risk for developing an increased prothrombin time, international normalized ratio (INR), and bleeding. The potential for this interaction between warfarin and VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is unknown.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

The carcinogenic potential of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) in animals has not been evaluated.

Miconazole nitrate was negative in a bacterial reverse mutation test, a chromosome aberration test in mice, and micronucleus assays in mice and rats.

Miconazole nitrate had no adverse effect on fertility in a study in rats at oral doses of up to 320 mg/kg/day, which is 89 times the maximum possible topical exposure of caregivers, assuming 100% absorption.

Use In Specific Populations

Pregnancy

Pregnancy Category C: There are no adequate and well-controlled studies of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) in pregnant women. Therefore, VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Miconazole nitrate administration has been shown to result in prolonged gestation and decreased numbers of live young in rats and in increased number of resorptions and decreased number of live young in rabbits at oral doses of 100 mg/kg/day and 80 mg/kg/day, which are 28 and 45 times the maximum possible topical exposure of caregivers, respectively, assuming 100% absorption.

Nursing Mothers

Safety and efficacy of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) have not been established in nursing mothers. It is not known if the active components of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) may be present in milk.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism of Action

The miconazole component of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is an antifungal agent. The mechanism of action of white petrolatum and zinc oxide for the adjunctive treatment of diaper dermatitis is unknown.

Pharmacodynamics

The human pharmacodynamics of Vusion (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is unknown [see CLINICAL PHARMACOLOGY for fungal pharmacodynamics].

Pharmacokinetics

The topical absorption of miconazole from VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) was studied in immunocompetent male and female infants and children (n=17) with diaper dermatitis complicated by documented candidiasis (microscopic evidence of pseudohyphae and/or budding yeast) ranging in age from 1 month to 21 months. After multiple daily applications to the affected area at every diaper change (approximately 5-12 times per day) for 7 days, the plasma concentrations of miconazole were below the lower limit of quantitation (LOQ) of 0.5 ng/mL in 15 out of 17 (88%) subjects. In the other 2 remaining subjects, the plasma concentrations of miconazole were 0.57 and 0.58 ng/mL, respectively at a single timepoint (4 hours after the last application) on Day 7.

Microbiology

The miconazole nitrate component in this product has been shown to have in vitro activity against Candida albicans, an organism that is associated with diaper dermatitis. The activity of miconazole nitrate against C. albicans is based on the inhibition of the ergosterol biosynthesis in the cell membrane. The accumulation of ergosterol precursors and toxic peroxides results in cytolysis of the cell. In vitro minimal inhibitory concentration (MIC) test results for C. albicans isolates obtained from treatment failures in Clinical Study 1 (see Clinical Studies) does not appear to indicate that resistance to miconazole nitrate was the reason for treatment failure. The clinical significance of the in vitro activity of miconazole nitrate against C. albicans in the setting of diaper dermatitis is unclear.

Clinical Studies

Study 1 was a double-blind, multicenter study in which VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) was compared to the zinc oxide and white petrolatum combination treatment and included 236 infants and toddlers with diaper dermatitis, complicated by candidiasis as documented by KOH tests that demonstrated psuedohyphae and/or budding yeasts. Study medication was applied at every diaper change for 7 days.

The primary endpoint was “Overall Cure” and required that subjects be both clinically cured (total resolution of all signs and symptoms of infection) and microbiologically cured (eradication of candidiasis). Primary efficacy was assessed 1 week following the end of treatment, at Day 14.

Study results are shown in the following table.

Overall Cure at Day 14

VUSION n=112	Zinc Oxide/White Petrolatum n=124
26 (23%)	12 (10%)

Two additional studies provided supportive evidence of the clinical efficacy of VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) in infants and toddlers with diaper dermatitis, some of whom cultured positive for C. albicans. However, candidal infection was not documented in the culture-positive subjects, as microscopic testing (e.g. KOH) was not done. Therefore, the positive culture results may have reflected colonization rather than infection.

What is VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) ?

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is a prescription skin medicine used to treat diaper rash that also has a yeast infection in children who are at least 4 weeks old and who have a normal immune system. VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) contains medicines that will help treat the yeast infection and the diaper rash, but you must also change your child's diapers very often so that your child is not wearing a wet or soiled diaper. Even if you use VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) , diaper rash will not go away if you do not keep your child's diaper area clean and dry. You should use water or a very mild cleanser to clean your child's diaper area. VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is not to be used to prevent diaper rash or to be used for more than 7 days.

Your health care provider will need to do a special test to tell if your child's diaper rash also has a yeast infection. Do not use VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) on your child's diaper rash unless your health care provider tells you that there is also a yeast infection.

Who should not use VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) ?

VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is not for treatment of all cases of diaper rash. VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) is only for diaper rash that also has a yeast infection. Most cases of diaper rash do not need the yeast medicine that is in VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) because most cases of diaper rash do not also have a yeast infection.

Do not use VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) on any other children or other family member.

Do not use VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) on your child's diaper rash if they are allergic to anything in it. See the end of this leaflet for a list of ingredients in VUSION (miconazole nitrate, 15% zinc oxide, and 81.35% white petrolatum) .
