Indications/Uses
Terbutaline, belonging to the beta agonists class of drugs, is a bronchodilator. The medication is chiefly indicated for the treatment of bronchial disease (such as asthma, tracheobronchitis), allergic bronchitis, slow heart rate, certain lung conditions (e.g., pulmonary edema) and collapsing trachea. The active ingredient in the medication, terbutaline, works by stimulating type 2 beta-adrenergic receptors. This stimulation of beta-2 receptors makes the muscle to relax and dilates the airways and blood vessels. This action is also effective to slow down or stop premature uterine contractions and labor.
