Premature birth is one of the leading causes of death in children under 5 years of age. Tocolytic inhibitors can prolong pregnancy time and are one of the important treatment measures for preterm birth. However, there are still many problems in the indications, efficacy monitoring, course of treatment, and safety monitoring of drugs in clinical use. Based on the relevant guidelines for preterm birth and in combination with the clinical practice, this paper reviews some problems in the use of tocolytics in preterm labor, so as to provide help for the management of preterm birth.
