ADVAIR DISKUS

BRAND NAME: Advair Diskus

GENERIC NAME: fluticasone propionate and salmeterol oral inhaler

DRUG CLASS AND MECHANISM:

Advair Diskus is an inhaled drug that is used to treat asthma and chronic bronchitis. In patients with asthma, the airways through which air moves in and out of the lungs can be narrowed by accumulation of mucus, spasm of the muscles that surround these airways, or swelling of the lining of the airways due to inflammation. Airway narrowing leads to symptoms of shortness of breath, wheezing, cough and congestion. Medications used in treating asthma include those that open airways, called bronchodilators, and those that reduce the inflammation. Advair Diskus contains a combination of salmeterol, a bronchodilator of the beta-2 agonist type, and fluticasone propionate, an anti-inflammatory corticosteroid. Beta-2 agonists are medications that attach to beta-2 receptors on the smooth muscle cells that surround the airways, causing the muscle cells to relax and opening the airways. Fluticasone propionate is a synthetic (man-made) corticosteroid of the glucocorticoid family which is related to the natural hormone, cortisol or hydrocortisone, produced by the adrenal glands. Glucocorticoid steroids have potent anti-inflammatory actions. In asthmatic patients, the suppression of inflammation within the airways reduces the muscle spasm that narrows the airways. At the same time, swelling and mucus are reduced. When used in lower doses, very little fluticasone propionate is absorbed into the body. When higher doses are used, fluticasone is absorbed and may cause side effects elsewhere in the body.

PREPARATIONS

STORAGE:

Advair Diskus should be stored at 36-86 ° F. It should be kept away from heat or flames and should not be punctured; it should not be frozen or placed in direct sunlight .

PRESCRIBED FOR

:Advair Diskus is used for the control of asthma in persons 12 years of age and older who require continuous treatment. Such patients may include those with frequent asthmatic episodes requiring bronchodilators or those with asthmatic episodes at night. Its action starts within 30 to 60 minutes and can last more than 12 hours. Advair Diskus is generally not needed in patients whose asthma can be controlled easily with infrequent administration of short acting inhalers. Advair Diskus should not be used to treat acute episodes of asthma. Advair Diskus 250/50 also is approved for the treatment of chronic obstructive pulmonary disease (COPD) associated with chronic bronchitis.

DOSING:

Advair Diskus is used twice daily (morning and evening). The Diskus device is held in one hand with the thumb of the other hand placed on the thumb-grip. The thumb is then pulled away as far as the device allows until the mouthpiece seems to click into position. With the Diskus then held horizontally and with the mouthpiece towards the patient, the lever is then slid away as far as it can go until it clicks. The patient breathes out as far as comfortable, then placing his mouth to the mouthpiece, breathes in quickly and deeply and holds his breath for about ten seconds.

DRUG INTERACTIONS:

No drug interactions have been described with Advair Diskus.

PREGNANCY:

Adequate studies of fluticasone or inhaled salmeterol 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. In some, but not all, pregnant animal models exposure to very high doses of oral salmeterol has led to offspring with birth defects. The concentrations of salmeterol in the blood after these very high doses, however, were much higher than the concentrations observed after inhalation. Salmeterol inhalation should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

NURSING MOTHERS:

It is not known if fluticasone propionate is secreted in breast milk. Other medications in the same class as fluticasone propionate are secreted into breast milk, but it is not known whether the small amounts that may appear in the milk have effects on nursing infants. In rats, salmeterol is excreted in milk. Therefore, caution should be exercised when salmeterol is administered to nursing women.

SIDE EFFECTS AND PRECAUTIONS:

Upper respiratory tract infections occur in 20-25% of patients using Advair Diskus. Headaches occur in about 1 in 8 patients who use it.
