Among the tocolytic agents used to suppress labor, magnesium sulfate and terbutaline, a beta agonist, are frequently used, as is nifedipine, a calcium channel blocker. Other choices include NSAIDs, such as indomethacin and sulindac. Beta agonists used less often are ritodrine, fenoterol, and salbutamol.
Many agents are used, and their success rates and side effects vary.
