Terbutaline Properties


Molecule Structure Image



Terbutaline is a β2-adrenergic receptor agonist. Terbutaline is currently used to delay preterm labor for 48 hours to allow for fetal lung maturity through steroid injections. It should not be used to prevent preterm labor or delay labor past 48-72 hours. Terbutaline is used as a fast-acting bronchodilator (often used as a short-term asthma treatment) and as a tocolytic to delay premature labor. It is used for prevention and reversal of bronchospasm in patients 12 years of age and older with reversible, obstructive airway disease, as well as symptomatic management of reversible bronchospasm associated with bronchitis and emphysema and also used acute IV and sub-Q therapy in selected women to inhibit uterine contractions in preterm labor (tocolysis) and prolong gestation when beneficial.
