Kalexate binds itself to potassium in your digestive tract. This helps prevent your body from absorbing too much potassium.

Kalexate is used to treat high levels of potassium in the blood, also called hyperkalemia.

Kalexate works differently from other medicines because it passes into your intestines without being absorbed into your blood stream.

Kalexate may also be used for purposes not listed in this medication guide.

• Generic Name: salmeterol

• Other Brand Names: Serevent Diskus, Serevent

Salmeterol is used together with other medicines (such as inhaled corticosteroids) to treat asthma and prevent bronchospasm in patients with asthma. When used regularly every day, inhaled salmeterol decreases the number and severity of asthma attacks. However, it will not relieve an asthma attack that has already started.

Salmeterol is also used to treat air flow blockage and prevent the worsening of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema. This medicine is also used to prevent wheezing caused by exercise (exercise-induced bronchospasm or EIB).

Salmeterol is a long-acting bronchodilator. Bronchodilators are medicines that are breathed in through the mouth to open up the bronchial tubes (air passages) in the lungs. They relieve cough, wheezing, shortness of breath, and troubled breathing by increasing the flow of air through the bronchial tubes.

This medicine is available only with your doctor's prescription.
