title: A randomised controlled study comparing valethamate bromide and placebo in shortening the duration of active labour.
abstract: The aim of this study is to compare the efficacy and safety of valethamate bromide and placebo against placebo in shortening the duration of active labour. A prospective randomised trial of 158 low-risk women in spontaneous labour was conducted. After evaluation of the patients according to exclusion criteria 30 women were given valethamate bromide (Group 1) and 32 women were given placebo (Group 2). Labour duration was the main outcome measure. The duration of the active phase after starting the treatment was similar in the two groups at 225 and 219 min, respectively. However, differences were not significant between the 2 groups. Side effects such as tachycardia, flushing of the face and dryness of mouth were noted with valethamate bromide administration. In conclusion, valethamate bromide did not significantly shortened the duration of active labour in nulliparous women with a singleton pregnancy at term.
