To Evaluate the Efficacy and Safety of Mifepristone in Reducing the Size & Symptoms of Uterine Leiomyoma/Fibroids.

Abstract

Uterine leiomyomas, or fibroids, are prevalent benign gynecological tumors affecting many women during their reproductive years. While surgical excision has long been the gold standard for fibroid treatment, the pharmacological management, including progesterone receptor modulators like mifepristone (RU 486), has garnered attention due to the reduced surgical approaches. However, there is a notable paucity of research on the effectiveness of mifepristone, on the same. This study seeks to evaluate the safety and efficacy of mifepristone in reducing uterine leiomyoma size and alleviating associated symptoms. Conducted prospectively, the study enrolled 20 pre-menopausal women, aged 18years or older, from Nanavati Max Super Speciality Hospital Mumbai, Maharashtra, India. Participants were selected based on specific inclusion criteria, including the presence of at least one uterine myoma with a minimum diameter of 2.5cm as confirmed by ultrasound. Participants had an average age of 39.75years and an average BMI of 27.58kg/m2. The study found that mifepristone significantly reduced uterine volume by 75%, with hemoglobin levels substantially improving from 9 gm/dL initially to 12.51 gm/dL after six months. Pain intensity, assessed using the Visual Analog Scale (VAS) score, gradually decreased from baseline to three-month, with all 20 patients reporting the complete absence of pelvic pain by six months. This prospective study highlights mifepristone's promise as a non-surgical approach to effectively reduce uterine fibroid volume, improve hemoglobin levels, and mitigate uterine blood loss in patients.
