Ritodrine hydrochloride（Cat No.:I002771）is a selective β2-adrenergic agonist used primarily to manage preterm labor. It works by stimulating β2 receptors in the uterine smooth muscle, leading to muscle relaxation and inhibition of contractions, which can delay premature childbirth. Ritodrine is administered intravenously under medical supervision to reduce the risk of early delivery. It is considered effective in some cases, though its use has declined due to side effects such as tachycardia, pulmonary edema, and maternal hypotension. Ritodrine’s application is typically reserved for high-risk preterm labor situations when other options are not suitable.
