True or False: Nifedipine, administered by mouth, is often the first treatment for delaying preterm labor.

• A. True
• B. False
• C. N/A
• D. Only in certain cases

Answer: (A)

Nifedipine is indeed often used as a first treatment for delaying preterm labor, particularly when oral administration is considered. It is a calcium channel blocker that helps to relax smooth muscle, including the uterine muscles, which can reduce contractions and delay labor. This treatment is beneficial in managing preterm labor as it can prolong gestation and help improve outcomes for the fetus.

The use of nifedipine in this context is supported by clinical guidelines, emphasizing its effectiveness and relative safety when administered correctly. Its ability to be given orally also makes it a convenient option compared to other tocolytics that may require intravenous administration. In practice, nifedipine is frequently chosen due to its favorable side effect profile and the clinical experience supporting its use.

Other treatment options exist for preterm labor, including various tocolytics with different mechanisms of action, but nifedipine’s specific attributes often make it a preferred initial choice in many clinical scenarios where pharmacologic intervention is needed.
