Medical uses

Linzagolix is indicated for treatment of moderate to severe symptoms of uterine fibroids in adult women of reproductive age and for treatment of intractable endometriosis.[1][7]

Available forms

Linzagolix is available as linzagolix choline, the choline salt of linzagolix, in the form of 100 and 200 mg film-coated oral tablets.[6]

Pharmacology

Pharmacodynamics

Linzagolix acts as a selective antagonist of the GnRH receptor, the biological target of GnRH.[6] By blocking this receptor, linzagolix prevents GnRH-mediated secretion of the gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH), and prevents them from signaling the gonads to produce sex hormones including estrogens, progesterone, and androgens.[6][11]

In clinical studies, linzagolix fully suppressed estradiol levels (median <20 pg/mL) in women at a dosage of 200 mg/day, whereas partial suppression of estradiol levels (median 20–60 pg/mL) occurred at a dosage 100 mg/day.[6] Progesterone levels were also variably suppressed with these dosages.[6]

Pharmacokinetics

The elimination half-life of linzagolix with repeated administration is approximately 15 hours.[6]
