Tocolytics

Tocolytics are a diverse class of labor-suppressing medications used primarily to manage acute preterm labor and delay preterm delivery Although they comprise pharmacologically distinct agents—including beta-2 adrenergic receptor agonists, calcium channel blockers, cyclooxygenase inhibitors, and oxytocin receptor antagonists—they collectively act by relaxing uterine smooth muscle and inhibiting myometrial contractions
