The EMA cleared RYEQO in July 2021 for the treatment of uterine fibroids.

RYEQO contains 40 mg relugolix, which reduces the amount of estrogen and other hormones produced by the ovaries, 1 mg estradiol, which may reduce the risk of bone loss, and 0.5 mg norethisterone acetate, a progestin that is necessary when women with a uterus take estrogen.

Richter's RYEQO sales came to EUR 1.8 million in H1 2022, according to the company's latest earnings report.
