[The inhibition of prostaglandin induced uterine contractions by diazoxide in vitro (author's transl)].

The tocolytic efficiency of Diazoxide, a benzothiadiazine derivative with pronounced musculotropic action, was tested on the isolated uteri of non-gravid and gravid rats. Regular uterine contractions were induced by the prostaglandines E2 and F2 alpha. Their amplitude and frequency could be suppressed totally or subtotally. Contraction intervals lasted 4--22 min. The basal tone was reduced in most cases.
