Terbutaline Indications
Terbutaline sulfate (Brethine®) is a medication that belongs to a class of drugs called beta-adrenergic receptor agonists -- often just called beta agonists for short. These drugs work by stimulating beta receptors in the body and decreasing the activity of mast cells in the lungs. As a result, terbutaline is often indicated for people with asthma or emphysema.
If you are taking terbutaline for asthma, keep in mind that it is designed to control the condition and should not be used to treat an asthma attack. You should also have a rescue medication, such as an albuterol inhaler, on hand for emergencies.
This medicine can also be used to help improve breathing in people with emphysema, a type of chronic obstructive pulmonary disease (COPD). Terbutaline cannot cure this condition, however, and it is often used in conjunction with other medications to treat emphysema.
