tocolítikus

Tocolytic refers to a class of medications used to suppress premature labor. These drugs work by relaxing the smooth muscle of the uterus, which can help to stop or slow down uterine contractions. The goal of tocolytic therapy is typically to delay birth long enough to allow for the administration of corticosteroids to the mother. These corticosteroids can accelerate the maturation of the fetal lungs, reducing the risk of respiratory distress syndrome if the baby is born prematurely.

Commonly used tocolytic agents include beta-adrenergic agonists like terbutaline and ritodrine, calcium channel blockers such as nifedipine, magnesium sulfate, and prostaglandin inhibitors like indomethacin. The choice of tocolytic agent depends on various factors, including the gestational age of the fetus, the presence of maternal or fetal contraindications, and the expected side effects.

While tocolytics can be effective in delaying preterm birth for a short period, they do not cure the underlying causes of premature labor and are generally not intended for long-term use. Their administration is often a bridge to allow for other interventions or to facilitate transfer to a facility with a specialized neonatal intensive care unit. Potential side effects for the mother can vary depending on the specific drug used and may include increased heart rate, tremors, nausea, dizziness, and fluid retention. Magnesium sulfate, for instance, can cause flushing and lethargy. The use of tocolytics is a medical decision made by healthcare professionals based on the specific circumstances of each pregnancy.
