Terbutaline (CAS NO.23031-25-6) is used as a treatment for premature labour is an off-label use not approved by the FAD. It is apregnancy category 'B' medication and is routinely prescribed to stop contractions. Terbutaline (CAS NO.23031-25-6) is currently on the World Anti-Doping Agency's list of prohibited drugs for Olympic athletes, except when administered by inhalation and a Therapeutic Use Exemption (TUE) has been obtained in advance.Orally disintegrating tablets by sublimation technique of Terbutaline sulphate have been developed.

 Terbutaline (CAS NO.23031-25-6) (trade names Brethine, Bricanyl, or Brethaire) is a β2-adrenergic receptor agonist, used as a fast-acting bronchodilator (often used as a short-term asthma treatment) and as a tocolytic to delay premature labour. The inhaled form of terbutaline starts working within 15 minutes and can last up to 6 hours .

 Terbutaline , with CAS number of 23031-25-6, can be called 5-(1-Hydroxy-2-tert-butylamino-ethyl)benzene-1,3-diol ; Terbutaline;(R)-α-[(tert-Butylamino)methyl]-3,5-dihydroxybenzyl alcohol ; (S)-α-[(tert-Butylamino)methyl]-3,5-dihydroxybenzyl alcohol ; 5-[(S)-1-Hydroxy-2-(tert-butylamino)ethyl]benzene-1,3-diol ; rac-5-[(R*)-2-[(1,1-Dimethylethyl)amino]-1-hydroxyethyl]-1,3-benzenediol .
