Relumina (relugolix) is a gonadotropin-releasing hormone (GnRH) receptor antagonist. GnRH is a hormone that stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH are hormones that stimulate the production of testosterone in men and estrogen and progesterone in women.
Drug class: GnRH receptor antagonist
Indications:
- Advanced prostate cancer
- Symptomatic uterine fibroids in premenopausal women
Mechanism of action:
Relugolix works by blocking the GnRH receptor on the pituitary gland. This prevents the pituitary gland from releasing LH and FSH. As a result, testosterone production in men and estrogen and progesterone production in women is reduced.
Dosage and administration:
Relugolix is taken once daily by mouth.
- For advanced prostate cancer, the recommended dose is 400 mg.
- For symptomatic uterine fibroids, the recommended dose is 200 mg.
Effectiveness:
Relugolix has been shown to be effective in reducing testosterone levels in men with advanced prostate cancer and in reducing heavy menstrual bleeding associated with uterine fibroids in premenopausal women.
Side effects:
The most common side effects of relugolix are hot flashes, fatigue, and headache. Other less common side effects include decreased libido, vaginal dryness, and bone loss.
Contraindications:
Relugolix is contraindicated in women who are pregnant or breastfeeding, in women with a history of thromboembolism, and in patients with a known allergy to relugolix or any of its ingredients.
Conclusion:
Relugolix is a safe and effective treatment for advanced prostate cancer and symptomatic uterine fibroids in premenopausal women. It is important to note that relugolix can cause side effects, such as hot flashes, fatigue, and headache. Patients should discuss the risks and benefits of relugolix with their doctor before starting treatment.
