Efficacy of different doses of mifepristone in the management of uterine leiomyoma in a tertiary care centre

Abstract

Leiomyoma or uterine fibroid are benign tumours that arise from the smooth muscles of the uterus. The leiomyomas are common gynaecological problem encountered among reproductive age group women. Mifepristone is the commonly used drug in the management of uterine leiomyoma. The objective of the study were to study the efficacy and safety of 10mg and 25mg of Mifepristone in the management of uterine fibroid. This is a randomized controlled Trial conducted in tertiary care centre. Hundred women with the diagnosis of uterine fibroid were taken up for the study. Group-A (n=50) were given Mifepristone 10mg and Group-B (n=50) were given Mifepristone 25mg daily for a period of 3 months. Reduction in the size of fibroid were assessed at the end of 3 months. At the end of 3months there was a significant reduction in both menstrual blood loss and fibroid volume in both the groups (p<0.001). There was a also significant improvement in haemoglobin levels in both the groups. When compared to Group –A (10mg Mifepristone) more side effects were noted in Group-B (25mg Mifepristone). Nausea and vomiting developed in 90% and 60% of patients in group A and B.Gastrointestinal discomfort developed in 80% and 50% of patients in group A and B. Both Mifepristone 10mg and 25mg had similar clinical outcomes but 10mg had better compliance and lower side effects. Hence, 10mg can be preferred over 25mg in order to bring about effective management of uterine fibroid.
