Ritodrine
Ritodrine is a beta-2 adrenergic agonist primarily used as a tocolytic agent to delay preterm labor by relaxing the smooth muscle of the uterus. It was one of the first medications approved specifically for preventing premature delivery, though its use has declined in many countries due to safety concerns and the availability of alternative tocolytic options.
A tocolytic medication used to stop premature labor contractions by relaxing the uterine muscles.

Used to manage preterm labor by delaying delivery when pregnancy continuation is desired. It helps prolong pregnancy to allow time for fetal maturation or for the mother to be transferred to a facility with appropriate neonatal care capabilities.
Acts as a beta-2 adrenergic receptor agonist, stimulating receptors in the uterine smooth muscle to cause relaxation and reduce contraction frequency and intensity. This delays cervical changes and prolongs pregnancy.
Administered intravenously initially, then possibly orally for maintenance. Contraindicated in conditions where prolonged pregnancy is undesirable (e.g., severe preeclampsia, fetal distress). Requires cardiac monitoring due to potential cardiovascular side effects including tachycardia and hypotension. Use has declined due to safety concerns compared to newer tocolytics.
