Overview
11 DESCRIPTION The active component of OMNARIS Nasal Spray is ciclesonide, a non-halogenated glucocorticoid having the chemical name pregna -1,4-diene-3,20-dione, 16,17-[[R-cyclohexylmethylene]bis(oxy)]-11-hydroxy-21-(2-methyl-1-oxopropoxy)-,(11β,16α)-. Ciclesonide is delivered as the R-epimer. The empirical formula is C 32 H 44 O 7 and its molecular weight is 540.7.
Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ciclesonide is a pro-drug that is enzymatically hydrolyzed to a pharmacologically active metabolite, C21-desisobutyryl-ciclesonide (des-ciclesonide or RM1) following intranasal application. Des-ciclesonide has anti-inflammatory activity with affinity for the glucocorticoid receptor that is 120-times higher than the parent compound. The precise mechanism through which ciclesonide affects allergic rhinitis symptoms is not known. Corticosteroids have been shown to have a wide range of effects on multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, and lymphocytes) and mediators (e.g., histamine, eicosanoids, leukotrienes, and cytokines) involved in allergic inflammation. 12.

( 1.1 , 1.2 ) 1.1 Treatment of Seasonal Allergic Rhinitis OMNARIS Nasal Spray is indicated for the treatment of nasal symptoms associated with seasonal allergic rhinitis in adults and children 6 years of age and older. 1.
Common Doses
- 200 mcg
Dosage
2 DOSAGE AND ADMINISTRATION Administer OMNARIS Nasal Spray by the intranasal route only. Prior to initial use, OMNARIS Nasal Spray must be gently shaken and then the pump must be primed by actuating eight times. If the product is not used for four consecutive days, it should be gently shaken and reprimed with one spray or until a fine mist appears. Illustrated patient’s instructions for proper use accompany each package of OMNARIS Nasal Spray. For Intranasal Use Only • 2 sprays per nostril once daily. (200 mcg) ( 2.1 , 2.
Contraindications
- 4 CONTRAINDICATIONS OMNARIS Nasal Spray is contraindicated in patients with a known hypersensitivity to ciclesonide or any of the ingredients of OMNARIS Nasal Spray [see Warnings and Precautions ( 5.3 )] . Patients with a known hypersensitivity to ciclesonide or any of the ingredients of OMNARIS Nasal Spray. ( 4 )
Side Effects
- 6 ADVERSE REACTIONS Systemic and local corticosteroid use may result in the following: • Epistaxis, nasal septal perforations, Candida albicans infection, impaired wound healing [see Warnings and Precautions ( 5.1 )] • Cataracts and glaucoma [see Warnings and Precautions ( 5.2 )] • Immunosuppression [see Warnings and Precautions ( 5.3 )] • Hypothalamic-pituitary-adrenal (HPA) axis effects, including growth reduction [see Warnings and Precautions ( 5.4 , 5.5 ), Use in Specific Populations ( 8.
Interactions
- 7 DRUG INTERACTIONS 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.
