Tocolytic

Tocolytic

Tocolytic (pronounced: toh-koh-LIT-ik) is a term used in medicine to describe medications that are used to suppress preterm labor. The word is derived from the Greek words "tokos" meaning childbirth and "lysis" meaning loosening.

Usage

Tocolytics are used in the management of preterm labor to delay delivery for up to 48 hours. This allows time for the administration of corticosteroids, which can improve fetal lung maturity and decrease complications of prematurity.

There are several types of tocolytic drugs, including:

• Beta-adrenergic agonists such as terbutaline
• Calcium channel blockers like nifedipine
• Prostaglandin inhibitors such as indomethacin
• Oxytocin antagonists like atosiban

Side Effects

Like all medications, tocolytics can have side effects. These can include:

• Palpitations
• Chest pain
• Shortness of breath
• Nausea
• Vomiting

Contraindications

Tocolytics are contraindicated in certain situations, including:

• Maternal heart disease
• Uncontrolled hypertension
• Preeclampsia
• Placental abruption
