abstract = "Objectives To evaluate the efficacy of oestradiol valerate/dienogest (E2V/DNG) for the treatment of heavy and/or prolonged menstrual bleeding without organic pathology based on the analysis of data from two identically designed double-blind, randomised studies. Methods Women aged ≥18 years with heavy and/or prolonged menstrual bleeding were randomised to E2V/DNG (n = 269) or placebo (n = 152) for 196 days. Objective changes in menstrual blood loss (MBL) volume were assessed using the alkaline haematin method. Results After six months of treatment, median MBL decreased by 88% with E2V/DNG compared with 24% with placebo. The greatest reduction was achieved at the first withdrawal bleed after treatment initiation and it was sustained with no loss of effect throughout treatment. Conclusion E2V/DNG was more effective than placebo in reducing MBL in women with heavy and/or prolonged menstrual bleeding without organic pathology. The reduction was largely achieved as early as the first withdrawal bleed, with further gradual improvement throughout treatment.",
