CICLESONIDE Drug Interactions: What You Need to Know

INTERACTIONS In clinical studies, concurrent administration of ciclesonide and other drugs commonly used in the treatment of asthma (albuterol, formoterol) had no effect on pharmacokinetics of des-ciclesonide [see Clinical Pharmacology ( 12.3 )] . In vitro studies and clinical pharmacology studies suggested that des-ciclesonide has no potential for metabolic drug interactions or protein binding-based drug interactions [see Clinical Pharmacology ( 12.3 )] . In a drug interaction study, co-administration of orally inhaled ciclesonide and oral ketoconazole, a potent inhibitor of cytochrome P450 3A4, increased the exposure (AUC) of des-ciclesonide by approximately 3.6-fold at steady state, while levels of ciclesonide remained unchanged.

ALVESCO is contraindicated in: the primary treatment of status asthmaticus or other acute episodes of asthma where intensive measures are required. patients with known hypersensitivity to ciclesonide or any of the ingredients of ALVESCO. Rare cases of hypersensitivity reactions with manifestations such as angioedema, with swelling of the lips, tongue and pharynx, have been reported. Patients with status asthmaticus or other acute episodes of asthma where intensive measures are required. ( 4 ) Patients with a known hypersensitivity to ciclesonide or any of the ingredients of ALVESCO. ( 4 )

AND PRECAUTIONS Candida albicans infection of the mouth and pharynx. Monitor patients periodically for signs of adverse effects on the oral cavity. Advise patients to rinse mouth following inhalation. ( 5.1 ) Potential worsening of existing tuberculosis: fungal, bacterial, viral, or parasitic infection; or ocular herpes simplex. More serious or even fatal course of chickenpox or measles in susceptible patients. Use caution in patients with above because of the potential for worsening of these infections. ( 5.3 ) Risk of impaired adrenal function when transferring from oral steroids to inhaled corticosteroids. Taper patients slowly from systemic corticosteroids if transferring to ALVESCO. ( 5.4 ) Hypercorticism, suppression of hypothalamic-pituitary-adrenal (HPA) function with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue ALVESCO slowly ( 5.5 ) Suppression of growth in children. Monitor growth routinely in pediatric patients receiving ALVESCO. ( 5.7 ) Development of glaucoma, increased intraocular pressure and posterior subcapsular cataracts. Monitor patients with a change in vision or with a history of increased intraocular pressure, glaucoma, and/or cataracts closely. ( 5.8 )

5.1 Oropharyngeal Candidiasis In clinical trials, the development of localized infections of the mouth and pharynx with Candida albicans occurred in 32 of 3038 patients treated with ALVESCO. Of the 32 reported cases, 20 occurred in 1394 patients treated with a total daily dose of 320 mcg of ALVESCO or higher. Most cases of Candida infection were mild to moderate. When such an infection occurs, treat it with appropriate local or systemic (i.e., oral antifungal) therapy and discontinue ALVESCO. Patients should rinse the mouth after inhalation of ALVESCO.

5.2 Acute Asthma Episodes ALVESCO is not a bronchodilator and is not indicated for rapid relief of bronchospasm or other acute episodes of asthma. Patients should be instructed to contact their physician immediately if episodes of asthma not responsive to their usual doses of bronchodilators occur during the course of treatment with ALVESCO. During such episodes, patients may require therapy with oral corticosteroids.

5.3 Immunosuppression and Risk of Infections Persons 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 susceptible children or adults using 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 affect the risk of developing a disseminated infection is not known. The safety and effectiveness of ALVESCO have not been established in pediatric patients less than 12 years of age and ALVESCO is not indicated for use in this population. The contribution of the underlying disease and/or prior corticosteroid treatment to the risk is also not known. If 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 Prescribing Information for VZIG and IG.) If chickenpox develops, treatment with antiviral agents may be considered. Inhaled corticosteroids should be used with caution, if at all, in patients with active or quiescent tuberculosis infection of the respiratory tract; untreated systemic fungal, bacterial, viral, or parasitic infections; or ocular herpes simplex.

5.4 Transferring Patients from Systemic Corticosteroid Therapy HPA Suppression/Adrenal Insufficiency Particular care is needed for patients who are transferred from systemically active corticosteroids to ALVESCO 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 infection (particularly gastroenteritis) or other conditions associated with severe electrolyte loss. Although ALVESCO may provide control of asthma symptoms during these episodes, in recommended doses it supplies less than normal physiological amounts of corticosteroid systemically and does NOT provide the mineralocorticoid activity that is necessary for coping with these emergencies. During periods of stress or a severe asthma attack, patients who have been withdrawn from systemic corticosteroids should be instructed to resume oral corticosteroids (in large doses) immediately and to contact their physicians for further instruction. These patients should also be instructed to carry a medical identification card indicating that they may need supplementary systemic corticosteroids during periods of stress or a severe asthma attack. Patients requiring oral corticosteroids should be weaned slowly from systemic corticosteroid use after transferring to ALVESCO. Prednisone reduction can be accomplished by reducing the daily prednisone dose by 2.5 mg on a weekly basis during ALVESCO therapy <span class="opacity-50 text-xs">[see Dosage and Administration ( 2 )]</span> . Lung function (FEV 1 or AM PEFR), beta-agonist use, and asthma symptoms should be carefully monitored during withdrawal of oral corticosteroids. In addition to monitoring asthma signs and symptoms, patients should be observed for signs and symptoms of adrenal insufficiency, such as fatigue, lassitude, weakness, nausea and vomiting, and hypotension. Unmasking of Allergic Conditions Previously Suppressed by Systemic Corticosteroids Transfer of patients from systemic steroid therapy to ALVESCO may unmask allergic conditions previously suppressed by the systemic steroid therapy, e.g., rhinitis, conjunctivitis, eczema, arthritis, and eosinophilic conditions.

Corticosteroid Withdrawal Symptoms

During withdrawal from oral steroids, some patients may experience symptoms of systemically active steroid withdrawal, e.g., joint and/or muscular pain, lassitude, and depression, despite maintenance or even improvement of respiratory function.

5.5 Hypercorticism and Adrenal Suppression ALVESCO will often help control asthma symptoms with less suppression of HPA function than therapeutically similar oral doses of prednisone. Since individual sensitivity to effects on cortisol production exists, physicians should consider this information when prescribing ALVESCO. Particular care should be taken in observing patients postoperatively or during periods of stress for evidence of inadequate adrenal response. Hypercorticism and adrenal suppression may occur when corticosteroids, including ALVESCO, are used at higher-than-recommended dosages <span class="opacity-50 text-xs">[see Dosage and Administration ( 2 )]</span> or patients at risk for such effects.

5.6 Reduction in Bone Mineral Density Decreases in bone mineral density (BMD) have been observed with long-term administration of products containing inhaled corticosteroids. The clinical significance of small changes in BMD with regard to long-term outcomes is unknown. Patients with major risk factors for decreased bone mineral content, such as prolonged immobilization, family history of osteoporosis, or chronic use of drugs that can reduce bone mass (e.g., anticonvulsants and oral corticosteroids) should be monitored and treated with established standards of care.

5.7 Effect on Growth Orally inhaled corticosteroids, including ALVESCO, may cause a reduction in growth velocity when administered to pediatric patients. The safety and effectiveness of ALVESCO have not been established in pediatric patients less than 12 years of age and ALVESCO is not indicated for use in this population. Monitor the growth of pediatric patients receiving ALVESCO routinely (e.g., via stadiometry). To minimize the systemic effects of orally inhaled corticosteroids, including ALVESCO, titrate each patient’s dose to the lowest dosage that effectively controls his/her symptoms <span class="opacity-50 text-xs">[see Use in Specific Populations ( 8.4 )]</span> .

5.8 Glaucoma and Cataracts Glaucoma, increased intraocular pressure, and cataracts have been reported following the administration of inhaled corticosteroids including ALVESCO. Therefore, close monitoring is warranted in patients with a change in vision or with a history of increased intraocular pressure, glaucoma, and/or cataracts. In a comparator control study of one-year treatment duration, 743 patients 18 years of age and older (mean age 43.1 years) with moderate persistent asthma were treated with ALVESCO 320 mcg twice daily and 742 were treated with a labeled dose of a comparator-inhaled corticosteroid appropriate for the patient population. Patients had an ophthalmology examination that included visual acuity, intraocular pressure measurement, and a slit lamp examination at baseline, 4, 8 and 12 months. Lens opacities were graded using the Lens Opacification System III.

After

52 weeks, CLASS I effects (minimally detected changes) were recorded in 36.1% of the ALVESCO-treated patients and in 38.4% of patients treated with the comparator-inhaled corticosteroid. The more severe CLASS III effects were recorded in 8.1% of the ALVESCO-treated patients and 9.2% of patients treated with the comparator-inhaled corticosteroid. Of those patients having a CLASS III effect, the incidence of posterior sub-capsular opacities was 0.9% and 0.5% in the ALVESCO- and comparator-treated patients, respectively.

5.9 Paradoxical Bronchospasm As with other inhaled asthma medications, bronchospasm, with an immediate increase in wheezing, may occur after dosing. If bronchospasm occurs following dosing with ALVESCO, it should be treated immediately with a fast-acting inhaled bronchodilator. Treatment with ALVESCO should be discontinued and alternative treatment should be instituted.
