title: A trial of oral ritodrine for the prevention of premature labour.
abstract: A double blind clinical trial of oral ritodrine for prevention of premature labour was conducted in 38 primigravidae in whom the internal os of the cervix was one or more fingerbreadths dilated at 28 to 32 weeks gestation. The results suggest that oral ritodrine may not be effective in preventing premature labour.
