DRUG CLASS AND MECHANISM: Terbutaline is a member of a class of drugs called beta adrenergic receptor agonists (stimulators) that is used for treating asthma and other diseases of the airways. Other drugs in the same class of drugs include albuterol (Proventil), metaproterenol (Alupent), pirbuterol (Maxair), and salmeterol (Serevent). Asthma is a breathing problem caused by narrowing of air passages (bronchial tubes) through which air moves in and out of the lungs. These airways can be narrowed due to the accumulation of mucus, spasm of the muscles that surround them (bronchospasm), or swelling of their linings due to the accumulation of fluid. Airway narrowing leads to shortness of breath, wheezing, and cough. Terbutaline is a bronchodilator, a medication that dilates (expands) air passages in the lungs. It attaches to beta adrenergic receptors on muscles surrounding the air passages, causing the muscles to relax and dilate the air passages. Wider air passages allow more air to flow in and out of the lungs. Increased airflow reduces shortness of breath, wheezing, and cough. Terbutaline also is used for delaying premature labor by relaxing the muscles of the uterus that are responsible for expelling the fetus at the time of delivery. The FDA approved terbutaline in 1974.
