Final answer:
Terbutaline is a medicine that acts as a bronchodilator and is also used in premature labor. It relaxes the uterine muscles and can have adverse reactions including hypokalemia, hypotension, and hyperglycemia.
Step-by-step explanation:
The medicine described in the question that acts as a bronchodilator and is also used in premature labor is Terbutaline. Terbutaline is a beta-2 adrenergic agonist that relaxes the uterine muscles, making it useful in stopping premature labor. However, it can also have adverse reactions including hypokalemia (low potassium levels), hypotension (low blood pressure), and hyperglycemia (high blood sugar levels).
Terbutaline is usually administered subcutaneously every 4 hours for 24 hours to stop premature labor.
