title: Calcium and calmodulin antagonism for inhibition of uterine contractions.
abstract: In search for a new tocolytic agent we investigated felodipine, a calmodulin-antagonizing drug. Felodipine reduced the spontaneous activity of 22 uterine strips taken from the uterus in the course of a cesarean section to 52 +/- 12% (mean +/- SEM) after 10 min, to 20 +/- 7% after 20 min and to 12 +/- 4% after 60 min (P less than 0.001).
