Final answer:
Long-acting beta-agonists like Salmeterol and Formoterol are inhaled medications that act as bronchodilators, providing extended airway relaxation for asthma patients when used in combination with corticosteroids.
Step-by-step explanation:
Long-acting beta-agonists used to treat asthma include medications such as Salmeterol and Formoterol. These are inhaled drugs that help open up the airways for extended periods.
Long-acting beta-agonists (LABAs) are a type of bronchodilator used in the management of asthma. They are typically prescribed for the long-term control of the disease, as they help to prevent asthma attacks by relaxing and opening up the airways in the lungs, making breathing easier. Unlike short-acting bronchodilators, which are used for immediate relief during an asthma attack, LABAs are used on a regular, ongoing basis and their effects can last for up to 12 hours. LABAs are usually inhaled via a metered-dose inhaler or dry powder inhaler, and for those who have difficulties using these devices, such as young children, the medication can be delivered through a nebulizer.
It is important to note that while LABAs are effective in keeping airways open, they should not be used alone to treat asthma. They are most effective when used in combination with an inhaled corticosteroid, which helps to reduce inflammation in the airways. This combined therapy efficiently controls symptoms and reduces the risk of severe asthma attacks. Examples of LABAs include Salmeterol and Formoterol, which are commonly prescribed and well-recognized for their efficacy in long-term asthma management.
