Description

Ritodrine is a β2-adrenergic receptor agonist that exhibits tocolytic activity. Ritodrine is clinically used to prevent preterm labor, as it decreases prostanoid signaling and inhibits uterine contractility. Ritodrine activates Ca2+-activated (SK/BK) K+ channels and ATP-sensitive K+ channels, potentially underlying its smooth muscle cell relaxant effects. Additionally, ritodrine may induce the formation of pruritic erythematous papular eruptions when used clinically.
