Brief Summary

Tocolytic agents are used for the treatment of preterm labor. It is unclear whether combination treatments of two tocolytic agents are more effective in stopping preterm labor compared to one. Therefore, the investigators propose a comparative effective trial of nifedipine plus indomethacin vs. nifedipine alone for the treatment of preterm labor
