FLUOCINOLONE ACETONIDE- fluocinolone acetonide_oil
Function and Efficacy
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in eczematous external otitis is unknown. Vasoconstrictor Assay Fluocinolone acetonide oil, 0. 01% ear drops is in the low to medium range of potency as compared with other topical corticosteroids in vasoconstrictor studies. However, similar blanching scores do not necessarily imply therapeutic equivalence. Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression HPA axis suppression was evaluated in 33 pediatric subjects 2 to 12 years old (20 subjects ages 2 to 6 years, 13 subjects ages 7 to 12 years) with moderate to severe stable atopic dermatitis. Subjects were treated with the formulation of fluocinolone acetonide oil, 0. 01% ear drops twice daily for 4 weeks. Baseline body surface area involvement was 50% to 75% in 15 subjects and greater than 75% in 18 subjects. Morning pre-stimulation cortisol and post-ACTH stimulation cortisol levels were obtained in each subject at the beginning of the trial and at the end of 4 weeks of treatment. At the end of treatment, 4 out of 18 subjects aged 2 to 5 years showed low pre-stimulation cortisol levels (3. 6 mug/dL; normal cortisol >7 mug/dL) but all had normal responses to 0. 25 mg of ACTH stimulation (cortisol > 18 mug/dL) [see Warnings and Precautions ( 5. 1 Topical corticosteroids can be absorbed from intact healthy skin. The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the product formulation and the integrity of the epidermal barrier. Occlusion, inflammation and/or other disease processes in the skin may increase percutaneous absorption. The use of pharmacodynamic endpoints for assessing the systemic exposure of topical corticosteroids may be necessary due to the fact that circulating levels are often below the level of detection. Once absorbed through the skin, topical corticosteroids are metabolized, primarily in the liver, and are then excreted by the kidneys. Some corticosteroids and their metabolites are also excreted in the bile.
Indication
Fluocinolone acetonide oil, 0. 01% ear drops is indicated for the topical treatment of chronic eczematous external otitis in adults and pediatric patients 2 years of age and older. 01% ear drops is a corticosteroid indicated for the topical treatment of chronic eczematous external otitis in adults and pediatric patients 2 years of age and older.
Usage and Dosage
Fluocinolone acetonide oil, 0. 01% ear drops is for otic administration only. Not for oral, ophthalmic, or intravaginal use. Apply fluocinolone acetonide oil, 0. 01% ear drops into the affected ear using the supplied ear dropper. To apply, tilt head to one side so that the ear is facing up. Then gently pull the ear lobe backward and upward and apply 5 drops of fluocinolone acetonide oil, 0. 01% ear drops into the ear. Keep head tilted for about a minute to allow fluocinolone acetonide oil, 0. 01% ear drops to penetrate lower into the ear canal. Gently pat excess material dripping out of the ear using a clean cotton ball. Follow these instructions twice each day for 7 to 14 days. Discontinue fluocinolone acetonide oil, 0. 01% ear drops when control of disease is achieved within 2 weeks, or contact the healthcare provider if no improvement is seen within 2 weeks. Do not use on the face, axillae, or groin unless directed by the healthcare provider. Do not apply to intertriginous areas due to the increased risk of local adverse reactions [see Adverse Reactions ( 6 8. 4 2 2 2.

Adverse Reactions
The following serious adverse reactions are discussed in more detail in other sections of the labeling: [see Warnings and Precautions ( 5. 4 [see Warnings and Precautions ( 5. 2 [see Warnings and Precautions ( 5. 3 The most commonly reported adverse reactions (>= 1%) were headache (3%), URI (2%), cough (2%), eczematous otitis (1%). 1 To report SUSPECTED ADVERSE REACTIONS, contact Padagis registered or FDA at 1-800-FDA-1088 or www. gov/medwatch. 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 trials that enrolled 154 subjects (adults and pediatric subjects 2 years and older) with chronic eczematous external otitis who were treated with five drops per ear of fluocinolone acetonide oil, 0. 01% ear drops twice daily for a maximum 14 days of treatment, the following adverse reactions were reported: Table 1: Adverse Reactions in >= 1% of Fluocinolone Acetonide Oil, 0. 01% Ear Drops-Treated Adult and Pediatric Subjects 2 Years of Age and Older with Chronic Eczematous External Otitis, N=154 Adverse Reaction n (%) Headache 4 (3) URI 3 (2) Cough 3 (2) Eczematous otitis 2 (1) The following adverse reactions have been identified during post-approval use of products containing topical corticosteroids. Because postmarketing adverse 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.

Special Population Medication
Risk Summary Available data from case reports, case series, and observational studies on fluocinolone acetonide use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. Observational studies suggest maternal use of high to super-high potency topical steroids may be associated with an increased risk of low birthweight infants. Advise pregnant women to use fluocinolone acetonide oil, 0. 01% ear drops on the smallest area of skin and for the shortest duration possible. Corticosteroids can cause fetal malformations in laboratory animals when administered systemically at relatively low dosage levels. Some corticosteroids cause fetal malformations after dermal application in laboratory animals. The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Risk Summary There is no information regarding the presence of fluocinolone acetonide in breast milk or its effects on the breastfed infant or on milk production. It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for fluocinolone acetonide oil, 0. 01% ear drops and any potential adverse effects on the breastfed infant from fluocinolone acetonide oil, 0. 01% ear drops or from the underlying maternal condition. The safety and effectiveness of fluocinolone acetonide oil, 0. 01% ear drops for the topical treatment of chronic eczematous external otitis have been established in pediatric patients aged 2 years and older. Safety and effectiveness of fluocinolone acetonide oil, 0. 01% ear drops in pediatric patients with chronic eczematous external otitis below the age of 2 years have not been established. Systemic Adverse Reactions in Pediatric Patients HPA Axis suppression, Cushing’s syndrome, and intracranial hypertension have been reported in pediatric patients receiving topical corticosteroids. Manifestations of adrenal suppression in pediatric patients include linear growth retardation, delayed weight gain, low plasma cortisol levels, and subnormal response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema. Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk for systemic adverse reactions than are adults when treated with topical corticosteroids [see Warnings and Precautions ( 5. 1 Evaluation in Peanut-Sensitive Pediatric Patients A clinical trial was conducted to assess the safety of the formulation of fluocinolone acetonide oil, 0. 01% ear drops, which contains refined peanut oil, in patients with known peanut allergies. The trial enrolled 13 pediatric subjects with atopic dermatitis, 6 to 17 years of age. Fluocinolone acetonide oil, 0. 01% ear drops is not approved for the treatment of atopic dermatitis. Of the 13 subjects, 9 were Radioallergosorbent Test (RAST) positive to peanuts and 4 had no peanut sensitivity (controls). The trial evaluated the subjects’ responses to both prick test and patch test utilizing refined peanut oil, the formulation of fluocinolone acetonide oil, 0. 01% ear drops and histamine/saline controls. Subjects were also treated with the formulation of fluocinolone acetonide oil, 0. 01% ear drops twice daily for 7 days. Prick test and patch test results for all 13 subjects were negative to the formulation of fluocinolone acetonide oil, 0. 01% ear drops and the refined peanut oil. One of the 9 peanut-sensitive subjects experienced an exacerbation of atopic dermatitis after 5 days of use on the formulation of fluocinolone acetonide oil, 0. 01% ear drops. Evaluation in Pediatric Patients 2 to 6 years old Use of the formulation of fluocinolone acetonide oil, 0. 01% ear drops in pediatric patients 2 to 6 years old is supported by open-label safety trials conducted in 33 pediatric subjects (20 subjects ages 2 to 6 years, 13 subjects ages 7 to 12 years) with moderate to severe stable atopic dermatitis. Baseline body surface area involvement was 50% to 75% in 15 subjects and greater than 75% in 18 subjects. Subjects were treated with the formulation of fluocinolone acetonide oil, 0. 01% ear drops twice daily for 4 weeks. Morning pre-stimulation cortisol and post-ACTH stimulation cortisol levels were obtained in each subject at the beginning of the trial and at the end of 4 weeks of treatment. At the end of treatment, 4 out of 18 subjects aged 2 to 5 years showed low pre-stimulation cortisol levels (3. 6 mug/dL; normal: cortisol > 7mug/dL) but all had normal responses to 0. 25 mg of ACTH stimulation (cortisol > 18 mug/dL) [see Clinical Pharmacology ( 12.
