Drugs that prevent Preterm Labor and immature Birth by suppressing Uterine Contractions (Tocolysis). Agents used to delay premature uterine activity include Magnesium Sulfate, beta-mimetics, Oxytocin antagonists, Calcium Channel inhibitors, and Adrenergic beta-Receptor Agonists. The use of intravenous alcohol as a tocolytic is now obsolete.
