Efficacy and Safety of Oral Tranexamic Acid in Women with Heavy Menstrual Bleeding and Fibroids

Abstract

AIM: To evaluate the efficacy and safety of oral, modified-release tranexamic acid in women with heavy menstrual bleeding and fibroids. MATERIALS & METHODS: This was a pooled analysis of two pivotal Phase III studies. Fibroids were evaluated by transvaginal ultrasonography. Menstrual blood loss (MBL) was measured via a validated alkaline hematin method. RESULTS: In women with and without fibroids, mean MBL was reduced compared with placebo across all treatment cycles (p < 0.001). Within the tranexamic acid group, more statistically significant (p < 0.001) reductions in MBL compared with placebo occurred in women with fibroids than in those without fibroids. Adverse events were similar between treatment groups. CONCLUSION: Tranexamic acid was well tolerated and reduced MBL in women with and without fibroids.
