NSAIDs (such as indomethacin) and calcium channel blockers (such as nifedipine) are the most likely to delay delivery for 48 hours, with the least amount of maternal and neonatal side effects. [46] Otherwise, tocolysis is rarely successful beyond 24 to 48 hours because current medications do not alter the fundamentals of labor activation. [47]
Ritodrine, sold under the brand name Yutopar, is a tocolytic drug used to stop premature labor. [2] [3] This drug has been removed from the US market, according to FDA Orange Book. It was available in oral tablets or as an injection and was typically used as the hydrochloride salt. The drug acts as a selective β 2-adrenergic receptor agonist. [4]
Atosiban is used to delay birth in adult women who are 24 to 33 weeks pregnant, when they show signs that they may give birth pre-term (prematurely). [4] These signs include regular contractions lasting at least 30 seconds at a rate of at least four every 30 minutes, [4] and dilation of the cervix (the neck of the womb) of 1 to 3 cm and an effacement (a measure of the thinness of the cervix ...
Terbutaline, sold under the brand names Bricanyl and Marex among others, is a β 2 adrenergic receptor agonist, used as a "reliever" inhaler in the management of asthma symptoms and as a tocolytic (anti-contraction medication) to delay preterm labor for up to 48 hours.
Hexoprenaline is a selective β 2 adrenergic receptor agonist used in the treatment of asthma. [2] Hexoprenaline is also used in some countries (such as Russia and Switzerland) as a tocolytic agent (i.e., labor suppressant), with the most common trade name being Gynipral.
Clenbuterol is a β 2 agonist with some structural and pharmacological similarities to epinephrine and salbutamol, but its effects are more potent and longer-lasting as a stimulant and thermogenic drug. [citation needed] It is commonly used for smooth muscle-relaxant properties as a bronchodilator and tocolytic.
Effects last between 45 and 180 minutes. [6] Common side effect include high blood pressure, vomiting, seizures, headache, and low blood pressure. [6] Other serious side effects include ergotism. [6] It was originally made from the rye ergot fungus but can also be made from lysergic acid.
Side effects of NETA include menstrual irregularities, headaches, nausea, breast tenderness, mood changes, acne, increased hair growth, and others. [6] NETA is a progestin, or a synthetic progestogen , and hence is an agonist of the progesterone receptor , the biological target of progestogens like progesterone . [ 1 ]
