Aerospan HFA information, interactions and side effects, Flunisolide, the active component of AEROSPAN™ (flunisolide) Inhalation Aerosol, is a corticosteroid having the chemical name 6α-Fluoro-11β, 16α, 17, 21 –tetrahydroxylpregna-1, 4diene-3, 20-dione cyclic-16, 17-acetal with acetone, hemihydrate and the following chemical structure:
Flunisolide is a white to creamy white crystalline powder with a molecular weight of 443.51 and an empirical formula of C24H31OF •½ H2O. It is soluble in acetone, ethyl alcohol and HFA-134a and practically insoluble in water.
AEROSPAN Inhalation Aerosol is a pressurized, metered-dose inhaler unit intended for oral inhalation only. The inhaler unit consists of a metal canister, a purple actuator, and a built-in gray spacer. Each unit contains a 0.24 % w/w solution of flunisolide in 10:90 w/w ethanol:1,1,1,2tetrafluoroethane (HFA 134a). After priming, each actuation delivers 139 mcg of flunisolide in 58 mg of solution from the canister valve and 80 mcg of flunisolide (equivalent to 78 mcg flunisolide anhydrous) from the spacer at a flow rate of 30 L/min for 4 seconds.
Using an in-vitro method at a fixed volume of 2 L, each actuation at the beginning of canister content delivers from the spacer 76 mcg (95% of the label claim) at a flow rate of 30 L/min, 61 mcg (76% of the label claim) at a flow rate of 20 L/min, 85 mcg (106% of the label claim) at a flow rate of 40 L/min, and 96 mcg (120% of the label claim) at a flow rate of 60 L/min. The actual amount of drug delivered to the lung may depend upon patient factors, such as timing and coordination between the actuation and inspiration and the strength and duration of the inspiration. Data show that both the one-and two-actuation doses are depleted by 75% or more after waiting one second between actuation and inhalation.
The 5.1-g net weight canister provides 60 metered actuations and the 8.9-g net weight canister provides 120 metered actuations.
AEROSPAN Inhalation Aerosol should be primed before using for the first time by releasing 2 test sprays into the air away from the face. In cases where the inhaler has not been used for more than 2 weeks, the inhaler should be primed again by releasing 2 test sprays into the air away from the face.
This product contains a built-in spacer. Do not use with any external spacer devices.
AEROSPAN Inhalation Aerosol is indicated for the maintenance treatment of asthma as prophylactic therapy in adult and pediatric patients 6 years of age and older. AEROSPAN Inhalation Aerosol is also indicated for asthma patients requiring oral corticosteroid therapy, where adding AEROSPAN Inhalation Aerosol may reduce or eliminate the need for oral corticosteroids.
Important Limitations of Use
AEROSPAN Inhalation Aerosol is NOT indicated for the relief of acute bronchospasm.
AEROSPAN Inhalation Aerosol is NOT indicated in children less than 6 years of age.
DOSAGE AND ADMINISTRATION
AEROSPAN Inhalation Aerosol should be administered by the orally inhaled route in asthmatic patients aged 6 years and older. This product contains a built-in spacer. Do not use with any external spacer or holding chamber devices. Instruct patients to prepare the inhaler for use by pulling the built-in purple actuator out from the gray spacer and snapping into an “L” shape prior to use. Pediatric patients should administer this product under adult supervision.
The onset and degree of symptom relief with orally inhaled corticosteroids is usually apparent within 2-4 weeks after the start of treatment, and varies with individual patients. The time to improvement in asthma control was not evaluated in clinical studies with AEROSPAN Inhalation Aerosol. For patients who do not respond adequately to the starting dose after 3-4 weeks of therapy, higher doses may provide additional asthma control. The safety and efficacy of AEROSPAN Inhalation Aerosol when administered in excess of recommended doses have not been established.
The recommended starting dosage and the highest recommended dosage of AEROSPAN Inhalation Aerosol are listed in Table 1.
Table 1: Recommended Doses of AEROSPAN Inhalation Aerosol
Note: In all patients it is desirable to titrate to the lowest effective dose once asthma stability is achieved.
||Recommended Starting Dose
||Highest Recommended Dose
|Adults and Adolescents 12 years of age and older†
||160 mcg twice daily
||320 mg twice daily*
|Children 6 to 11 years†
||80 mcg twice daily
||160 mcg twice daily*
|* Higher doses have not been studied.
† For Patients Currently Receiving Chronic Oral Corticosteroid Therapy: Clinical studies with AEROSPAN Inhalation Aerosol did not evaluate patients on oral corticosteroids. However, clinical studies with therapeutic doses of flunisolide CFC inhalation aerosol did show efficacy in the management of asthmatics dependent or maintained on systemic corticosteroids. Reduce the dose of prednisone no faster than 2.5 mg/day on a weekly basis, beginning after at least 1 week of therapy with AEROSPAN. Monitor patients carefully for signs of asthma instability, including serial objective measures of airflow, and for signs of adrenal insufficiency during steroid taper and following discontinuation of oral corticosteroid therapy.
Dosage Forms And Strengths
AEROPSAN is an inhalation aerosol in a pressurized metered dose inhaler with a built in spacer that delivers 60 or 120 metered 80 mcg doses.
Storage And Handling
AEROSPAN Inhalation Aerosol is supplied as a pressurized lined aluminum canister in boxes of one. Each canister is supplied with a two-piece plastic purple actuator and gray spacer assembly, and tear-off patient’s instructions, including a Patient Information and an illustrated. Instructions for Using Your AEROSPAN Inhalation Aerosol.
The following canister sizes are available: 8.9 g net weight, providing 120 metered actuations (trade size, NDC 75989-550-12); 5.1 g net weight providing 60 metered actuations (hospital size, NDC 75989-550-63); 5.1 g net weight providing 60 metered actuations (professional sample, NDC 75989-550-06).
Prime the inhaler by releasing two test sprays into the air away from the face before first use of AEROSPAN Inhalation Aerosol, and when the inhaler has not been used for more than 2 weeks.
Instruct patients to prepare the inhaler for use by pulling the built-in purple actuator out from the gray spacer and snapping into an “L” shape prior to use.
The appearance of a white ring on the orifice of the actuator and inside the spacer is normal. The performance of AEROSPAN Inhalation Aerosol is not affected by this residue. No cleaning is required.
When not in use, keep AEROSPAN Inhalation Aerosol out of reach of children. Pediatric patients should only administer AEROSPAN Inhalation Aerosol under adult supervision.
The plastic purple actuator and gray spacer assembly supplied as part of AEROSPAN Inhalation Aerosol should not be used with any other product canisters; and the actuator from other products should not be used with an AEROSPAN Inhalation Aerosol canister. Do not separate the purple actuator from the gray spacer. Do not use this product with any external spacer or holding chamber devices.
The labeled amount of medication in each actuation (80 mcg flunisolide) cannot be assured after 120 metered actuations (or 60 metered actuations in the hospital and sample size canisters), even though the canister is not completely empty and will continue to operate. The inhaler (canister plus actuator) should be discarded when the labeled number of actuations have been used.
Avoid spraying in eyes.
Contents under pressure: Do not puncture. Do not use or store near heat or open flame. Protect from freezing temperatures and prolonged exposure to sunlight. Exposure to temperatures above 120°F (49°C) may cause bursting. Never throw into fire or incinerator.
Store at 25 °C (77 °F); excursions permitted to 15 to 30 °C (59 to 86 °F). For best results, the canister should be at room temperature before use.
Systemic and local corticosteroid use may result in the following:
- Candida albicans infection
- Immunosuppression, increased risk of infections
- Hypercorticism and adrenal suppression
- Reduction in bone mineral density
- Effects on growth
- Glaucoma, increased intraocular pressure and cataracts
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.
The following table shows the adverse reactions that were reported in patients previously receiving bronchodilators and/or orally inhaled corticosteroids in two double-blind, placebo-controlled US clinical trials, in which 519 adult and pediatric patients age 4-78 years (279 males and 240 females) were treated with the AEROSPAN Inhalation Aerosol (80 mcg to 320 mcg twice daily for 12 weeks) or placebo. The mean duration of exposure was 76.7, 78.2, 80.5, and 69.4 days for AEROSPAN Inhalation Aerosol 80 mcg, 160 mcg, 320 mcg, and placebo, all dosed twice daily, respectively. The table includes all reactions that occurred at a rate of > 3% in any AEROSPAN Inhalation Aerosol group. In considering these data, the increased average duration of exposure for AEROSPAN Inhalation Aerosol patients should be taken into account, compared with placebo-treated patients.

The following other adverse reactions occurred in patients in these clinical trials using AEROSPAN Inhalation Aerosol with an incidence of 1 to 3% and were more common in AEROSPAN Inhalation Aerosol than in the placebo group.
Body As A Whole: abdominal pain, chest pain, infection, neck pain
Digestive System: diarrhea, gastroenteritis, nausea, oral moniliasis
Metabolic And Nutritional Disorders: edema
Musculoskeletal System: myalgia
Nervous System: dizziness, insomnia, migraine
Respiratory System: bronchitis, laryngitis, voice alteration
Skin And Appendages: erythema multiforme
Special Senses: conjunctivitis, ear pain, taste perversion
Urogenital System: dysmenorrhea, vaginitis
Long-Term Clinical Trials
Two 52-week open label safety trials of AEROSPAN Inhalation Aerosol were conducted in 162 asthma patients 12 to 60 years of age and in 152 asthma patients 4 to 11 years of age. The adverse reaction profile exhibited in these trials was similar to that seen in the two 12-week studies.
Adverse Reactions from Other Sources
The following additional adverse reactions were derived from clinical trials conducted with flunisolide CFC inhalation aerosol with a frequency of ≥ 1% and not described above:
Body as a Whole: flu, decreased appetite, chills, increased appetite, weight gain, malaise, peripheral edema, sweating, weakness
Gastrointestinal System: upset stomach, heartburn, constipation, gas, abdominal fullness
Cardiovascular System: palpitations, hypertension, tachycardia
Nervous System: headache, irritability, shakiness, anxiety, depression, faintness, fatigue, hyperactivity, hypoactivity, moodiness, numbness, vertigo
Respiratory System: cold symptoms, nasal congestion, upper respiratory tract infection, chest congestion, hoarseness, runny nose, sinus congestion, sinus drainage, sinus infection, sneezing, sputum, wheezing, chest tightness, bronchospasm, dyspnea, head stuffiness, nasal irritation, pleurisy, pneumonia, sinus discomfort
Skin and Appendages: eczema, pruritus, acne, urticaria
Special Senses: loss of smell, loss of taste, ear infection, blurred vision, eye discomfort, eye infection
Hemic and Lymph: capillary fragility, enlarged lymph nodes
Mouth and Throat: sore throat, dry throat, glossitis, mouth irritation, phlegm, throat irritation
In clinical studies with flunisolide, localized infections with Candida albicans or Aspergillus niger have occurred in the mouth and pharynx and occasionally in the larynx. If oropharyngeal candidiasis develops, treat with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing with AEROSPAN Inhalation Aerosol therapy, but at times therapy with AEROSPAN Inhalation Aerosol may need to be temporarily interrupted under close medical supervision. Rinsing the mouth after inhalation is advised.
Acute Asthma Episodes
AEROSPAN Inhalation Aerosol is not a bronchodilator and is not indicated for rapid relief of bronchospasm. Instruct patients to contact their physician immediately when episodes of asthma that are not responsive to bronchodilators occur during the course of treatment with AEROSPAN Inhalation Aerosol. During such episodes, patients may require therapy with systemic corticosteroids.
Patients who are using 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 children or adults on corticosteroids. In such children or adults who have not had these diseases or been properly immunized, 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 prior corticosteroid treatment to the risk is also not known. If a patient is exposed to chickenpox, prophylaxis with varicella-zoster immune globulin (VZIG) may be indicated. If a patient is exposed to measles, prophylaxis with pooled intramuscular immunoglobulin (IG) may be indicated. If chickenpox develops, treatment with antiviral agents may be considered.
Because of the potential for worsening infections, use inhaled corticosteroids with caution, if at all, in patients with untreated active or quiescent tuberculosis infection of the respiratory tract; untreated systemic fungal, bacterial, parasitic or viral infections; or ocular herpes simplex.
Transfer from Systemic Corticosteroids
Particular care is needed in patients who are transferred from systemically active corticosteroids to AEROSPAN Inhalation Aerosol because deaths due to adrenal insufficiency have occurred in asthmatic patients during and after transfer from systemic corticosteroids to less systemically available inhaled corticosteroids. After withdrawal from systemic corticosteroids, a number of months are required for recovery of hypothalamic-pituitary-adrenal (HPA) function.
Patients who have been previously maintained on 20 mg or more per day of prednisone (or its equivalent) may be most susceptible, particularly when their systemic corticosteroids have been almost completely withdrawn. During this period of HPA suppression, patients may exhibit signs and symptoms of adrenal insufficiency when exposed to trauma, surgery or infections (particularly gastroenteritis) or other conditions associated with severe electrolyte loss. Although AEROSPAN Inhalation Aerosol may provide control of asthmatic symptoms during these episodes, in recommended doses it supplies less than the physiologic amounts of glucocorticoid (cortisol) systemically and does NOT provide the mineralocorticoid activity that is necessary for coping with these emergencies.
During periods of stress or a severe asthmatic attack, patients who have been withdrawn from systemic corticosteroids should be instructed to resume systemic steroids immediately and to contact their physician for further instruction. Instruct these patients to carry a warning card indicating that they may need supplementary systemic steroids during periods of stress or a severe asthma attack.
Wean patients requiring oral corticosteroids slowly from systemic corticosteroid use after transferring to AEROSPAN Inhalation Aerosol. Prednisone reduction can be accomplished by reducing the daily prednisone dose by 2.5 mg/day on a weekly basis or morning peak expiratory flow rate [AM PEF]), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of oral corticosteroids. In addition to monitoring asthma signs and symptoms, observe patients for signs and symptoms of adrenal insufficiency such as fatigue, lassitude, weakness, nausea and vomiting, and hypotension.
Transfer of patients from systemic corticosteroid therapy to AEROSPAN Inhalation Aerosol may unmask allergic conditions previously suppressed by the systemic corticosteroid therapy, e.g. rhinitis, conjunctivitis, eczema, arthritis, and eosinophilic conditions.
During withdrawal from oral corticosteroids, some patients may experience symptoms of systemically active corticosteroid withdrawal, e.g., joint or muscular pain, lassitude and depression, despite maintenance or even improvement of respiratory function.
Hypercorticism and Adrenal Suppression
In responsive patients, flunisolide may permit control of asthmatic symptoms with less suppression of HPA axis function than therapeutically equivalent oral doses of prednisone. Since flunisolide is absorbed into the circulation and can be systemically active, the beneficial effects of AEROSPAN Inhalation Aerosol in minimizing or preventing HPA axis dysfunction may be expected only when recommended dosages are not exceeded and individual patients are titrated to the lowest effective dose. Since individual sensitivity to effects on cortisol production exists, physicians should consider this information when prescribing AEROSPAN Inhalation Aerosol.
Because of the possibility of systemic absorption of inhaled corticosteroids, observe patients treated with AEROSPAN Inhalation Aerosol carefully for any evidence of systemic corticosteroid effects. Particular care should be taken in observing patients post-operatively or during periods of stress for evidence of inadequate adrenal response.
It is possible that systemic corticosteroid effects such as hypercorticism and adrenal suppression may appear in a small number of patients, particularly at higher doses. If such changes occur, reduce the AEROSPAN Inhalation Aerosol dose slowly, consistent with accepted procedures for management of asthma symptoms and for tapering of systemic corticosteroids.
Reduction in Bone Mineral Density
Decreases in bone mineral density (BMD) have been observed with long-term administration of products containing inhaled corticosteroids, including flunisolide. The clinical significance of small changes in BMD with regard to long-term outcomes is unknown. Monitor patients with major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of osteoporosis, postmenopausal status, tobacco use, advanced age, poor nutrition, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants and corticosteroids) and treat with established standards of care.
Effects on Growth
Orally inhaled corticosteroids, including flunisolide, may cause a reduction in growth velocity when administered to pediatric patients. Monitor the growth of children and adolescents receiving AEROSPAN Inhalation Aerosol. To minimize the systemic effects of orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, each titrate each patient to his/her lowest effective dose .
Glaucoma and Cataracts
Glaucoma, increased intraocular pressure, and cataracts have been reported in patients following the long-term administration of inhaled corticosteroids, including flunisolide. Monitor patients closely, especially patients with a change in vision or with a history of increased intraocular pressure, glaucoma, or cataracts.
As with other inhaled asthma medications, bronchospasm may occur with an immediate increase in wheezing after dosing. If bronchospasm occurs following dosing with AEROSPAN Inhalation Aerosol, treat immediately with a fast-acting inhaled bronchodilator. Discontinue treatment with AEROSPAN Inhalation Aerosol immediately and institute alternative therapy.
Patient Counseling Information
Advise patients that localized fungal infections occurred in the mouth and pharynx in some patients. If oropharyngeal candidiasis develops, treat with appropriate local or systemic (i.e., oral) antifungal therapy while still continuing with AEROSPAN Inhalation Aerosol therapy, but at times therapy with AEROSPAN Inhalation Aerosol may need to be temporarily interrupted under close medical supervision. Rinsing the mouth after inhalation is advised.
Status Asthmaticus and Acute Asthma Symptoms
Advise patients that AEROSPAN Inhalation Aerosol is not a bronchodilator and is not intended to be used to treat status asthmaticus or to relieve acute asthma symptoms. Treat acute asthma symptoms with an inhaled, short-acting beta-2 agonist such as albuterol. Instruct patients to contact their physicians immediately if there is deterioration of their asthma.
Warn patients who are on immunosuppressant doses of AEROSPAN Inhalation Aerosol to avoid exposure to chickenpox or measles and, if exposed, to consult their physician without delay. Inform patients of potential worsening of existing tuberculosis, fungal, bacterial, viral, or parasitic infections, or ocular herpes simplex.
Hypercorticism and Adrenal Supression
Advise patients that AEROSPAN Inhalation Aerosol may cause systemic corticosteroid effects of hypercorticism and adrenal suppression. Additionally, instruct patients that deaths due to adrenal insufficiency have occurred during and after transfer from systemic corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to AEROSPAN Inhalation Aerosol.
Reduction in Bone Mineral Density
Advise patients who are at an increased risk for decreased BMD that the use of corticosteroids may pose an additional risk. Monitor patients and, where appropriate, treat for this condition.
Reduced Growth Velocity
Inform patients that orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, may cause a reduction in growth velocity when administered to pediatric patients. Physicians should closely follow the growth of children and adolescents taking corticosteroids by any route.
Long-term use of inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, may increase the risk of some eye problems (cataracts or glaucoma); consider regular eye examinations.
Use Daily for Best Effect
Advise patients to use AEROSPAN Inhalation Aerosol at regular intervals as directed, since its effectiveness depends on regular use. Individual patients will experience a variable time to onset and degree of symptom relief, and the full benefit may not be achieved until treatment has been administered for 2 to 4 weeks. If symptoms do not improve in that time frame or if the condition worsens, patients should not increase dosage, but should contact the physician immediately.
Advise patients not to stop Aerospan Inhalation Aerosol or change the dose without talking with a healthcare provider. Advise patients that if they miss a dose to take the next scheduled dose when it is due.
Instructions for Use
Aerospan Inhalation Aerosol contains a built-in spacer. Do not use with any external spacer or holding chamber devices. Instruct patients to prepare the inhaler for use by pulling the built-in purple actuator out from the gray spacer and snapping into an “L” shape prior to use. With use, the appearance of a white ring on the orifice of the actuator and inside the spacer is normal. The performance of AEROSPAN Inhalation Aerosol is not affected by this residue. No cleaning is required.
Carcinogenesis, Mutagenesis, Impairment of Fertility
In a 22 month study in Swiss mice, flunisolide at oral doses up to 500 mcg/kg/day (approximately 3 and 4 times the maximum recommended daily inhalation dose [MRDID] in adults and children on a mg/m² basis) did not demonstrate any carcinogenic effects.
In a two year study in Sprague Dawley rats, administration of flunisolide in the diet at a dose of 2.5 mcg/kg/day (less than MRDID in adults or children on a mg/m² basis) resulted in an increased incidence of mammary gland adenomas and islet cell adenomas of the pancreas in females. The significance of these findings for humans is unknown. There were no significant increases in the incidence of any tumor type in female rats at a dose of 1.0 mcg/kg/day (less than MRDID in adults or children on a mg/m² basis), or in male rats at a dose of 2.5 mcg/kg/day (less than MRDID in adults or children on a mg/m² basis).
Flunisolide showed no mutagenic activity when tested in in vitro bacterial assay systems (Ames Assay and the Rec-assay) and no clastogenic activity when tested in the in vitro chromosomal aberration assay using Chinese Hamster CHL cells and in the in vivo mouse bone marrow chromosomal aberration assay.
Studies on the effects of flunisolide on fertility in female rats showed that flunisolide, at an oral dose of 200 mcg/kg/day (approximately 3 times MRDID on a mg/m² basis) impaired fertility, but was devoid of such effects at doses up to 40 mcg/kg/day (less than MRDID on a mg/m² basis).
Use In Specific Populations
Pregnancy Category C
There are no adequate and well-controlled studies of flunisolide in pregnant women. AEROSPAN Inhalation Aerosol should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
As with other corticosteroids, flunisolide has been shown to be teratogenic and fetotoxic in rabbits and rats at approximately 1 and 3 times the maximum recommended daily inhalation dose on a mg/m² basis, respectively (doses of 40 and 200 mcg/kg/day, respectively).
Experience with oral corticosteroids since their introduction in pharmacologic, as opposed to physiological, doses suggests that rodents are more prone to teratogenic effects from corticosteroids than humans.
Hypoadrenalism may occur in infants born of mothers receiving corticosteroids during pregnancy. Such infants should be carefully monitored.
It is not known whether flunisolide is excreted in human milk. Because other corticosteroids are excreted in human milk, caution should be exercised when AEROSPAN Inhalation Aerosol is administered to nursing women.
The safety and effectiveness of AEROSPAN Inhalation Aerosol has been studied in children 4-17 years of age. In clinical studies, the efficacy of AEROSPAN Inhalation Aerosol was not established in children 4-5 years of age, although the adverse reaction profile observed in patients exposed to AEROSPAN Inhalation Aerosol was similar between the 4-5 year age group (n=21), the 6-11 year age group (n=210), the 12-17 year age group (n=30), and those patients 18 years of age and older (n=258). The safety and effectiveness of AEROSPAN Inhalation Aerosol has not been studied in patients less than 4 years of age.
Effects on Growth
Controlled clinical studies have shown that orally inhaled corticosteroids may cause a reduction in growth velocity in pediatric patients. In these studies, the mean reduction in growth velocity was approximately one cm per year (range 0.3 to 1.8 cm per year) and appears to depend upon the dose and duration of exposure. This effect was observed in the absence of laboratory evidence of hypothalamic-pituitary-adrenal (HPA) axis suppression, suggesting that growth velocity is a more sensitive indicator of systemic corticosteroid exposure in pediatric patients than some commonly used tests of HPA axis function. The long-term effects of this reduction in growth velocity associated with orally inhaled corticosteroids, including the impact on final adult height, are unknown. The potential for “catch up” growth following discontinuation of treatment with orally inhaled corticosteroids has not been adequately studied. The growth of pediatric patients receiving orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, should be monitored routinely (e.g., via stadiometry). The potential growth effects of prolonged treatment should be weighed against clinical benefits obtained and the risks/benefits of treatment alternatives. To minimize the systemic effects of orally inhaled corticosteroids, including AEROSPAN Inhalation Aerosol, each patient should be titrated to the lowest dose that effectively controls his/her symptoms.
The potential effect of AEROSPAN on growth rates in children was assessed in a 52 week randomized, placebo controlled study conducted in 242 prepubescent children age 4 to 9.5 years (145 males, 97 females) with mild persistent asthma. Treatment groups were AEROSPAN 160 mcg twice daily and placebo. Growth velocity was estimated for each patient using the slope of the linear regression of height over time using observed data in the intent to treat population who had at least 3 height measurements. The mean growth velocities were 6.19 cm/year in the placebo group and 6.01 cm/year in the AEROSPAN treated group (difference from placebo -0.17 cm/year; 95% CI: -0.58, 0.24).
Clinical studies of AEROSPAN Inhalation Aerosol included 21 patients 65 to 78 years of age exposed to AEROSPAN Inhalation Aerosol. These studies did not include sufficient numbers of patients aged 65 years and over to determine whether they respond differently from younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.
In a double-blind, placebo-controlled study, 18 mg of flunisolide was administered via the CFC formulation over a three-hour period (nine times the maximum labeled daily dose) in 94 patients with acute asthma, and no clinically deleterious effects were observed.
AEROSPAN Inhalation Aerosol is contraindicated in the following conditions:
Primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required.
