title: [The value of magnesium pyrrolidone carboxylate in true cervix dystocia. A double blind versus placebo study].
abstract: The efficacy of spasmolytics in cervix dystocia during labor is very contested. For this reason the authors studied the action of pyrrolidone carboxylate of magnesium for this indication in a double-blind versus placebo study (48 patients divided in two groups). Strict inclusion criteria and homogeneity of the two groups of patients allowed them to find out that the use of this particular magnesium salt reduced significantly the length of labor. Consequently the authors assess that spasmolytics work not only through their placebo effect, which is thought by some authors.
