Flunisolide

INDICATIONS AND USAGE Flunisolide nasal solution is indicated for the treatment of the nasal symptoms of seasonal or perennial rhinitis. Flunisolide nasal solution should not be used in the presence of untreated localized infection involving nasal mucosa.

DOSAGE AND ADMINISTRATION Adults: The recommended starting dose of Flunisolide Nasal Solution is 2 sprays (50 mcg) in each nostril 2 times a day (total dose 200 mcg/day). If needed, this dose may be increased to 2 sprays in each nostril 3 times a day (total dose 300 mcg/day). Pediatric Patients 6 to 14 years: The recommended starting dose of Flunisolide Nasal Solution is 1 spray (25 mcg) in each nostril 3 times a day or 2 sprays (50 mcg) in each nostril 2 times a day (total dose 150 to 200 mcg/day). Flunisolide Nasal Solution is not recommended for use in pediatric patients less than 6 years of age as safety and efficacy studies, including possible adverse effects on growth, have not been conducted. Maximum total daily doses should not exceed 8 sprays in each nostril for adults (total dose 400 mcg/day) and 4 sprays in each nostril for pediatric patients under 14 years of age (total dose 200 mcg/day). Since there is no evidence that exceeding the maximum recommended dosage is more effective and increased systemic absorption would occur, higher doses should be avoided. After the desired clinical effect is obtained, the maintenance dose should be reduced to the smallest amount necessary to control the symptoms. Approximately 15% of patients with perennial rhinitis may be maintained on as little as 1 spray in each nostril per day. For priming and repriming the nasal spray unit after storage: The patient should remove the dust cover. Put two fingers on “shoulders” of pump unit, and place thumb on bottom of bottle. Push bottle with thumb FIRMLY and QUICKLY 5-6 times or until fine spray appears. Now your pump is primed. The patient must prime the pump unit again if it has not been used for 5 days or more, or if it has been disassembled for cleaning. Directions for Use: A patient leaflet of instructions accompanies each package of Flunisolide Nasal Solution. WARNING: Do not spray in eyes.

CONTRAINDICATIONS Hypersensitivity to any of the ingredients.

ADVERSE REACTIONS Adverse reactions reported in controlled clinical trials and long-term open studies in 595 patients treated with flunisolide nasal solution are described below. Of these patients, 409 were treated for 3 months or longer, 323 for 6 months or longer, 259 for 1 year or longer, and 91 for 2 years or longer. In general, side effects elicited in the clinical studies have been primarily associated with the nasal mucous membranes. The most frequent complaints were those of mild transient nasal burning and stinging, which were reported in approximately 45% of the patients treated with flunisolide nasal solution in placebo-controlled and long-term studies. These complaints do not usually interfere with treatment; in only 3% of patients was it necessary to decrease dosage or stop treatment because of these symptoms. Approximately the same incidence of mild transient nasal burning and stinging was reported in patients on placebo as was reported in patients treated with flunisolide nasal solution in controlled studies, implying that these complaints may be related to the vehicle or the delivery system. The incidence of complaints of nasal burning and stinging decreased with increasing duration of treatment. Other side effects reported at a frequency of 5% or less were: nasal congestion, sneezing, epistaxis and/or bloody mucous, nasal irritation, watery eyes, sore throat, nausea and/or vomiting, and headaches. As with other nasally inhaled corticosteroids, nasal septal perforations have been reported in rare instances with the use of flunisolide nasal solutions. Temporary or permanent loss of the sense of smell and taste have also been reported with the use of flunisolide nasal solutions. Systemic corticosteroid side effects were not reported during the controlled clinical trials. If recommended doses are exceeded, or if individuals are particularly sensitive, symptoms of hypercorticism, i.e., Cushing’s syndrome, could occur. Cases of growth suppression have been reported for intranasal corticosteroids (including flunisolide nasal solution) ( see PRECAUTIONS, Pediatric Use ) .

DESCRIPTION Flunisolide Nasal Solution USP, 0.025% is intended for administration as a spray to the nasal mucosa. Flunisolide, the active component of flunisolide nasal solution, is an anti-inflammatory steroid. Flunisolide is represented by the following structural formula: C 24 H 31 FO 6 Mol. Wt. 434.51 Chemical Name: 6α-fluoro-11β, 16α,17,21-tetrahydroxypregna-1,4-di-ene-3,20-dione cyclic 16,17-acetal with acetone (USAN). Flunisolide is a white to creamy white crystalline powder. It is soluble in acetone, sparingly soluble in chloroform, slightly soluble in methanol, and practically insoluble in water. It has a melting point of about 245°C. After initial priming (5 to 6 sprays), each spray of the unit delivers a metered droplet spray of 100 mg formulation containing 25 mcg of flunisolide. The size of the droplets produced by the unit is in excess of 8 microns to facilitate deposition on the nasal mucosa. The contents of one nasal spray bottle delivers 200 sprays. Each 25 mL flunisolide nasal solution spray bottle contains 6.25 mg (0.25 mg/mL). Each mL Contains: ACTIVE : Flunisolide 0.25 mg (0.025%); INACTIVES : Propylene Glycol, Polyethylene Glycol 3350, Butylated Hydroxyanisole, Edetate Disodium, Sodium Citrate, Citric Acid, and Purified Water. Sodium Hydroxide and/or Hydrochloric Acid may be added to adjust pH (5.1 – 5.4). PRESERVATIVE : Benzalkonium Chloride 0.01%. Flunisolide (Structural formula)

OVERDOSAGE Flunisolide, infused intravenously, at doses up to 4 mg/kg in mice, rats and dogs (approximately 45, 300 and 90 times, respectively, the maximum recommended daily intranasal dose in adults and children on a mg/m 2 basis) was without lethality.
