FLUNISOLIDE- flunisolide nasal spray_solution

Flunisolide has demonstrated potent glucocorticoid and weak mineralocorticoid activity in classical animal test systems. As a glucocorticoid, it is several hundred times more potent than the cortisol standard. Clinical studies with flunisolide have shown therapeutic activity on nasal mucous membranes with minimal evidence of systemic activity at the recommended doses. A study in approximately 100 patients that compared the recommended dose of Flunisolide Nasal Solution with an oral dose providing equivalent systemic amounts of flunisolide has shown that the clinical effectiveness of Flunisolide Nasal Solution, when used topically as recommended, is due to its direct local effect and not to an indirect effect through systemic absorption. Following administration of flunisolide to man, approximately half of the administered dose is recovered in the urine and half in the stool: 65 to 70% of the dose recovered in urine is the primary metabolite, which has undergone loss of the 6alpha fluorine and addition of a 6beta hydroxy group. Flunisolide is well absorbed but is rapidly converted by the liver to the much less active primary metabolite and to glucuronate and/or sulfate conjugates. Because of first-pass liver metabolism, only 20% of the flunisolide reaches the systemic circulation when it is given orally whereas 50% of the flunisolide administered intranasally reaches the systemic circulation unmetabolized. The plasma half-life of flunisolide is 1 to 2 hours. The effects of flunisolide on hypothalamic-pituitary-adrenal (HPA) axis function have been studied in adult volunteers. Flunisolide was administered intranasally as a spray in total doses over 7 times the recommended dose (2,200 mcg, equivalent to 88 sprays/day) in 2 subjects for 4 days, about 3 times the recommended dose (800 mcg, equivalent to 32 sprays/day) in 4 subjects for 4 days, and over twice the recommended dose (700 mcg, equivalent to 28 sprays/day) in 6 subjects for 10 days. Early morning plasma cortisol concentrations and 24-hour urinary 17-ketogenic steroids were measured daily. There was evidence of decreased endogenous cortisol production at all three doses. In controlled studies, Flunisolide Nasal Solution was found to be effective in reducing symptoms of stuffy nose, runny nose and sneezing in most patients. These controlled clinical studies have been conducted in 488 adult patients at doses ranging from 8 to 16 sprays (200-400 mcg) per day and 127 pediatric patients at doses ranging from 6 to 8 sprays (150 to 200 mcg) per day for periods as long as 3 months. In 170 patients who had cortisol levels evaluated at baseline and after 3 months or more of flunisolide treatment, there was no unequivocal flunisolide-related depression of plasma cortisol levels. Clinical studies have shown that improvement is usually apparent within a few days after starting Flunisolide Nasal Solution. The mechanisms responsible for the anti-inflammatory action of corticosteroids and for the activity of the aerosolized drug on the nasal mucosa are unknown.

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: Pediatric Patients 6 to 14 years: 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.

PATIENT INSTRUCTIONS
Flunisolide Nasal Solution USP, 0. 025% en dash HOW TO USE YOUR NASAL PUMP UNIT en dash Your nasal spray unit with the pump requires no assembly. IMPORTANT INFORMATION ON FLUNISOLIDE NASAL SOLUTION: You should use Flunisolide Nasal Solution at regular intervals since its effectiveness depends on its regular use (see below). It may take 1-2 weeks before full relief is obtained. You should contact your physician if symptoms do not improve, if the condition worsens, or if sneezing, nasal irritation, or bleeding occurs. You should contact your physician if you know you have been exposed to chickenpox or measles. TO PRIME: 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 a fine spray appears. Now your pump is primed. You must prime the pump unit again if you have not used it for 5 days or more, or if you have disassembled it for cleaning. If the solution is delivered in a stream of liquid, it may fail to provide maximum benefit and cause some discomfort. A fine mist can be produced only by a rapid and firm pumping action. Once your pump is primed, it’s ready to use. NOTE: Keep dust cover on the pump unit when not in use. TO USE: Gently blow nose to clear nostrils. If nose is blocked, use medicine your doctor has recommended to open nasal passages. Remove the dust cover. Be sure the pump unit is primed. Place the spray tip into one nostril (tip should not reach far into nose). Bend head forward Hold pump as shown, resting back of index finger against upper lip. BE CAREFUL THAT FINGERS DO NOT SLIP OFF THE PUMP AS YOU SPRAY. Point the tip toward the BACK and OUTER SIDE of the nose. Close other nostril with finger. Pump the spray by pushing bottle with thumb FIRMLY and QUICKLY and sniff gently at the same time. Your doctor will tell you whether to pump once or twice in each nostril. After spraying in nostril, remove unit from nose and bend head back for a few seconds to let spray spread over back of nose. Repeat Steps 5 and 6 in other nostril. You may feel brief burning or stinging after using the spray. Keep dust cover on the pump unit when not in use. TO CLEAN: If spray nozzle becomes clogged, DO NOT ATTEMPT TO CLEAR IT USING A POINTED OBJECT. Remove the pump unit from bottle. Soak only the pump unit in warm water. Squirt several times while holding under water. Make sure the pump unit is dry. Assemble as before with 5 or 6 sprays before use.

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 To report SUSPECTED ADVERSE REACTIONS, contact Oceanside Pharmaceuticals at 1-800-321-4576 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

Hypersensitivity to any of the ingredients.

WARNINGS
The replacement of a systemic corticosteroid with a topical corticoid can be accompanied by signs of adrenal insufficiency, and in addition some patients may experience symptoms of withdrawal, e.g., joint and/or muscular pain, lassitude and/or depression. Patients previously treated for prolonged periods with systemic corticosteroids and transferred to flunisolide should be carefully monitored to avoid acute adrenal insufficiency in response to stress. When transferred to flunisolide, careful attention must be given to patients previously treated for prolonged periods with systemic corticosteroids. This is particularly important in those patients who have associated asthma or other clinical conditions, where too rapid a decrease in systemic corticosteroids may cause a severe exacerbation of their symptoms. The use of flunisolide with alternate-day prednisone systemic treatment could increase the likelihood of HPA suppression compared to a therapeutic dose of either one alone. Therefore, flunisolide treatment should be used with caution in patients already on alternate-day prednisone regimens for any disease. Persons who are on drugs that suppress the immune system are more susceptible to infections than healthy individuals. Chickenpox and measles, for example, can have a more serious or even fatal course in non-immune pediatric patients or adults on corticosteroids. In such pediatric patients or adults who have not had these diseases, particular care should be taken to avoid exposure. How the dose, route and duration of corticosteroid administration affects the risk of developing a disseminated infection is not known. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If a nonimmune patient is exposed to chickenpox, prophylaxis with varicella zoster immune globulin (VZIG) may be indicated. If exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. (See the respective package insert for complete VZIG and IG prescribing information.) If chickenpox develops, treatment with antiviral agents may be considered.
