OBJECTIVE For the first line tocolysis, calcium channel blockers (CCB)--oral nifedipine (Adalate®) or intravenous nicardipine (Loxen®)--are frequently used in France. No study compared nifedipine and nicardipine in management of threatened preterm delivery. From data of a French observational study, we compared factors associated with the use of nifedipine and nicardipine. Efficacy and toleranc...
