title: [A study of the comparative efficiency of ifenprodil and ritodrine in the treatment of threatened premature labour (author's transl)].
abstract: The study compares a sequential test of a beta mimetic drug (ritodrine) and an alpha inhibitor (ifenoprodil) to show that the beta mimetic drug is superior in treating threatened premature labour, because it has a success rate of 90 per cent whereas the second has a success rate of 45 per cent. Ritodrine produces secondary effects in 69 per cent of cases.
