FDA's recommendations on the use of long-acting {beta}2 agonists in the management of asthma

Abstract:
The revised labeling for long-acting β(2) agonists (LABAs) by the Food and Drug Administration (FDA) is controversial and in part is inconsistent with the 2007 National Asthma Education and Prevention Program asthma guidelines. Two large randomized controlled studies, the Serevent Nationwide Surveillance (SNS) study and the Salmeterol Multicenter Asthma Research Trial (SMART), and a 2008 meta-analysis conducted by the FDA were the main sources of information used to determine the label changes. A paucity of large, well-designed, controlled, prospective studies evaluating the asthma-related risks associated with LABAs makes it difficult to reach a consensus regarding how best to use LABAs in patients with asthma.

Antiasthma Drugs: β2-Adrenoceptor Agonists
One class of bronchodilators includes β2-adrenoceptor agonists. These agents target the β2-adrenoceptors located on bronchial smooth muscle cells. By stimulating these receptors, β2-agonists induce relaxation in these...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
