...t-acting, long-acting, and ultra-long-acting drugs. Some FDA-approved short-acting B2 agonists (SABAs) are albuterol, levalbuterol, metaprotereno terbutaline, and they are prescribed for bronchospasm caused by COPD, bronchial asthma, or emphysema. Some SABAs have off-label uses; albuterol is used in the treatment of hyperkalemia, and terbutaline Beta2 Receptor Agonists and Antagonists
can have cardiac side effects such as elevated cardiac enzymes and arrhythmias although this is usually seen after several hours of continuous infusion.
Medications, Biologics, and Immunotherapy for Pediatric AsthmaShort-acting beta-2 agonists (SABA): Albuterol (salbutamol), levalbuterol, and terbutaline are used as quick relief therapy or rescue therapy to ease symptoms as they reverse bronchoconstriction.
Evidence supports the use of parenteral tocolysis, most often with the beta-2-agonist medication terbutaline, to improve the success of ECV; most studies evaluating the various aspects of ECV aspects include using a tocolytic agent.
Some SABAs have off-label uses; albuterol is used in the treatment of hyperkalemia, and terbutaline is administered to postpone preterm labor and manage vascular extravasation.
