GENERIC NAME: fluticasone propionate oral inhaler
BRAND NAMES: Flovent (Discontinued), Flovent Diskus, Flovent HFA
DRUG CLASS AND MECHANISM: Fluticasone propionate is a man-made steroid of the glucocorticoid family which is related to the naturally-occurring steroid hormone, cortisol or hydrocortisone, produced by the adrenal glands. Glucocorticoid steroids have potent anti-inflammatory actions. When used as an inhaler, fluticasone travels to the airways in the lung. In asthmatic patients, the suppression of inflammation within the airways reduces the spasm of muscle cells that surround the airways as well as the accumulation of fluid and cells that accompanies the inflammation which lead to narrowing of the airways. The narrowing makes it difficult to get air into and out of the lungs. When used in lower doses, very little fluticasone is absorbed into the body. When higher doses are used, fluticasone is absorbed and may cause side effects elsewhere in the body. The FDA approved fluticasone in March 1996.
GENERIC AVAILABLE: No
PREPARATIONS: Inhalation aerosol: 44, 110, and 220 mcg/inhalation. Inhalation Powder (Diskhaler): 50, 100, and 250 mcg/inhalation
STORAGE: Fluticasone should be kept at room temperature, 4-30 C (39-86 F), and the aerosol should be shaken well before each use.
PRESCRIBED FOR: Fluticasone is used for the treatment of asthma in patients 4 years of age old or older who require oral steroid treatment. Fluticasone is not used for acute episodes of asthma; a faster acting dilator of the airways such as albuterol (Ventolin, Proventil, Proventil HFA, AccuNeb, Vospire, ProAir) should be used for acute episodes of asthma.
DOSING: Doses vary from patient to patient.
The recommended dose for the aerosol is 88 to 440 mcg twice daily.
The recommended dose for the Diskhaler is 100 to 1000 mcg twice daily. Following administration, the mouth should be rinsed thoroughly with water or mouthwash to minimize dry mouth, irritation of the throat, and hoarseness.
The aerosol inhaler must be cleaned at least once a week.
If a bronchodilator aerosol spray (a spray that causes the airways to expand), for example, albuterol (Proventil; Ventolin), is used, it should be used first, and then 5-15 minutes later fluticasone should be used.
DRUG INTERACTIONS: Ritonavir (Norvir), atazanavir (Reyataz), clarithromycin (Biaxin), indinavir (Crixivan), itraconazole (Sporanox), ketoconazole, nelfinavir (Viracept), and telithromycin (Ketek) may increase levels of fluticasone in the body by reducing the breakdown of fluticasone by liver enzymes. This may increase side effects of fluticasone.
PREGNANCY: Adequate studies of fluticasone during pregnancy have not been done. Fluticasone use during pregnancy should be avoided unless the potential benefit justifies the potential but unknown risk to the fetus.
NURSING MOTHERS: It is not known if fluticasone is secreted in breast milk. Other medications in the same class as fluticasone are secreted into breast milk. It is not known whether the small amounts that may appear in the milk affect the infant.
SIDE EFFECTS: The most common side effects of fluticasone are headache, upper respiratory infections, throat irritation, nasal congestion, nasal discharge, and hoarseness or difficulty speaking. Fluticasone may also cause bronchospasms (wheezing). Bronchospasms should be treated with a rescue inhaler.
