Clinical Summary

A short-acting beta-2 adrenergic agonist that is primarily used as a bronchodilator agent to treat ASTHMA. Albuterol is prepared as a racemic mixture of R(-) and S(+) stereoisomers. The stereospecific preparation of R(-) isomer of albuterol is referred to as levalbuterol.

Therapeutic Applications

Albuterol (also known as salbutamol) is used to treat wheezing and shortness of breath caused by breathing problems such as asthma. It is a quick-relief medication. Albuterol belongs to a class of drugs known as bronchodilators. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school.

Therapeutic Applications

This medication is used to prevent and decrease symptoms (wheezing and trouble breathing) caused by asthma and ongoing lung disease (chronic obstructive pulmonary disease-COPD, including chronic bronchitis and emphysema). This inhaler contains 2 medications: fluticasone and vilanterol. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing the swelling of the airways in the lungs to make breathing easier. Vilanterol belongs to a class of drugs known as long-acting beta agonists. It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. When used alone, long-acting beta agonists (like vilanterol) may rarely increase the risk of serious (sometimes fatal) asthma-related breathing problems. However, combination inhaled corticosteroid and long-acting beta agonists, such as this product, do not increase the risk of serious asthma-related breathing problems. For asthma treatment, this product should be used when breathing problems are not well controlled with one asthma-control medication (such as inhaled corticosteroid) or if your symptoms need combination treatment. Before using this medication, it is important to learn how to use it properly. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks. If an asthma attack occurs, use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) as prescribed.

Clinical Summary

A muscarinic antagonist structurally related to ATROPINE but often considered safer and more effective for inhalation use. It is used for various bronchial disorders, in rhinitis, and as an antiarrhythmic.

Therapeutic Applications

Ipratropium is used to control and prevent symptoms (wheezing and shortness of breath) caused by ongoing lung disease (chronic obstructive pulmonary disease-COPD which includes bronchitis and emphysema). It works by relaxing the muscles around the airways so that they open up and you can breathe more easily. Controlling symptoms of breathing problems can decrease time lost from work or school. For preventing symptoms of lung disease, this medication must be used regularly to be effective. Use your quick-relief inhaler (such as albuterol, also called salbutamol in some countries) for wheezing or sudden shortness of breath unless otherwise directed by your doctor. Ipratropium does not work as fast as your quick-relief inhaler, but may sometimes be used to relieve symptoms of wheezing or sudden shortness of breath if so prescribed by your doctor.

Therapeutic Applications

Montelukast is used to control and prevent symptoms caused by asthma (such as wheezing and shortness of breath). It is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your quick relief inhaler. Montelukast is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). Since there are other allergy medications that may be safer (see also Warning section), this medication should be used for this condition only when you cannot take other allergy medications or they do not work well. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks or breathing problems. If an asthma attack or sudden shortness of breath occurs, use your quick-relief inhaler as prescribed. This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.

Therapeutic Applications

This product is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma and ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). Controlling symptoms of breathing problems helps you stay active. This inhaler contains 3 medications: fluticasone, umeclidinium, and vilanterol. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing swelling of the airways in the lungs to make breathing easier. Umeclidinium belongs to a class of drugs known as anticholinergics and vilanterol is a LABA medication. Both drugs work by relaxing the muscles around the airways so that they open up and you can breathe more easily. Both drugs are also known as bronchodilators. When used alone, long-acting beta agonists (such as vilanterol) may rarely increase the risk of serious (sometimes fatal) asthma-related breathing problems. However, combination products containing both an inhaled corticosteroid and long-acting beta agonist, such as this product, do not increase the risk of serious asthma-related breathing problems. For asthma treatment, this product should be used when breathing problems are not well controlled with two asthma-control medications (such as inhaled corticosteroid and long-acting beta agonist) or if your symptoms need combination treatment. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden shortness of breath. If sudden breathing problems occur, use your quick-relief inhaler as prescribed.

Clinical Summary

An anti-IgE, recombinant, humanized monoclonal antibody which specifically binds to the C epsilon3 domain of IMMUNOGLOBULIN E, the site of high-affinity IgE receptor binding. It inhibits the binding of IgE to MAST CELLS and BASOPHILS to reduce the severity of the allergic response and is used in the management of persistent allergic ASTHMA.

Therapeutic Applications

Omalizumab is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma that is due to year-round allergens. Controlling symptoms of asthma helps you maintain your normal activities and cuts down on time lost from work or school. Omalizumab may also be used to treat nasal polyps or to treat hives from an unknown cause (chronic idiopathic urticaria-CIU). This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden asthma attacks. If an asthma attack occurs, use your quick-relief inhaler (such as albuterol, salbutamol) as prescribed.
