Serevent Serevent review
Pharmacy and Drugs

     .: Prescription

Serevent, or Salmeterol, is an adrenergic bronchodilator breathed in through the mouth to open up the air passages of the lungs. Serevent is different from most Bronchodialators. It is a long-acting bronchodilator that is used with anti-inflammatory medication to prevent asthma attacks. It does not act quickly enough to relieve an asthma attack that has already started.

Be sure to tell your doctor of any allergies you have whether it is to medication or food, preservatives, or dyes. Also tell your doctor of any other medications you are taking, including vitamins and supplements, and any medical conditions you may have.

It is very important that you take this medicine exactly as your doctor tells you to. Do not take more or less medicine than directed, and don’t stop taking Serevent without discussing it with your doctor first.

If you miss a dose of this medicine, take it as soon as you remember, then space out the remaining doses for that day equally. Do NOT double doses.

Tell your doctor immediately if any of the following side effects occur: dizziness; feeling of choking, irritation, or swelling in throat; flushing or redness of skin; hives; increased shortness of breath; skin rash; swelling of face, lips, or eyelids; tightness in chest or wheezing, or troubled breathing.

SEREVENT DISKUS (salmeterol xinafoate inhalation powder) contains salmeterol xinafoate as the racemic form of the 1-hydroxy-2-naphthoic acid salt of salmeterol. The active component of the formulation is salmeterol base, a highly selective beta2-adrenergic bronchodilator. The chemical name of salmeterol xinafoate is 4-hydroxy-a1-[[[6-(4-phenylbutoxy)hexyl]amino] methyl]-1,3-benzenedimethanol, 1-hydroxy-2-naphthalenecarboxylate. Salmeterol xinafoate is a white to off-white powder with a molecular weight of 603.8, and the empirical formula is C25H37NO4· C11H8O3. It is freely soluble in methanol; slightly soluble in ethanol, chloroform, and isopropanol; and sparingly soluble in water. SEREVENT DISKUS is a specially designed plastic inhalation delivery system containing a double-foil blister strip of a powder formulation of salmeterol xinafoate intended for oral inhalation only. The DISKUS®, which is the delivery component, is an integral part of the drug product. Each blister on the double-foil strip within the unit contains 50 mcg of salmeterol administered as the salmeterol xinafoate salt in 12.5 mg of formulation containing lactose (which contains milk proteins). After a blister containing medication is opened by activating the DISKUS, the medication is dispersed into the airstream created by the patient inhaling through the mouthpiece. Under standardized in vitro test conditions, SEREVENT DISKUS delivers 47 mcg when tested at a flow rate of 60 L/min for 2 seconds. In adult patients with obstructive lung disease and severely compromised lung function (mean forced expiratory volume in 1 second [FEV1] 20% to 30% of predicted), mean peak inspiratory flow (PIF) through a DISKUS was 82.4 L/min (range, 46.1 to 115.3 L/min).
