Summary:

      The objective of this study was to determine the magnitude and duration of the reduction in
      pH (acidification) following a single dose of Acidform vaginal gel containing 3, 4, or 5 g
      compared with hydroxyethylcellulose placebo gel (4 g) or no treatment. Vaginal pH was
      measured 1 h, 6 h, 12 h, 24 h, then once daily for 7 days. In addition, the participants were
      assessed for an exploratory endpoint to the determine effect of one dose of Acidform gel (3,
      4 or 5 g) or placebo gel (4 g) or no treatment, on asymptomatic bacterial vaginosis (BV).
