How Elago 200 mg Tablet works

Endometriosis develops when tissue that is similar to the kind that is normally located in the uterus starts to grow outside of the uterus . Such growth leads to various symptoms like pain during periods, pelvic pain between periods, and pain during sexual intercourse . The growths themselves are referred to as lesions and frequently develop on the ovaries, fallopian tubes, and other areas around the uterus, including the bowel or bladder . The growth of these lesions is dependent upon the estrogen hormone .

Elago 200 mg Tablet is an orally-administered, nonpeptide small molecule gonadotropin-releasing hormone (GnRH) receptor antagonist that inhibits endogenous GnRH signaling by binding competitively to GnRH receptors in the pituitary gland . Administration of elagolix results in dose-dependent suppression of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), leading to decreased blood concentrations of the ovarian sex hormones, estradiol and progesterone.

Side Effects

Most common adverse reactions (>5%) in clinical trials included hot flushes and night sweats, headache, nausea, insomnia, amenorrhea, anxiety, arthralgia, depression-related adverse reactions and mood changes.

Toxicity

In case of overdose, monitor the patient for any signs or symptoms of adverse reactions and initiate appropriate symptomatic treatment, as needed . Common adverse reactions of elagolix include hot flush, headache, nausea, insomnia, mood alterations, amenorrhea, depression, anxiety, arthralgia, bone loss, changes in menstrual bleeding patterns, suicidal ideation and behavior, exacerbation of existing mood disorders, and/or hepatic transaminase elevations .

The recommended duration of use for elagolix is up to 24 months for the 150 mg once daily dose and up to six months for the 200 mg twice daily dose, as it causes a dose-dependent decrease in bone mineral density (BMD) . BMD loss is greater with increasing duration of use and may not be completely reversible after stopping treatment . For women with moderate hepatic impairment, the recommended dosage is 150 mg once daily for up to six months .

Precaution

• Bone Loss: Dose- and duration-dependent decreases in bone mineral density (BMD) that may not be completely reversible. Assess BMD in women with additional risk factors for bone loss
• Reduced Ability to Recognize Pregnancy: Elago 200 mg Tablet may alter menstrual bleeding, which may reduce the ability to recognize pregnancy. Perform testing if pregnancy is suspected. Discontinue if pregnancy is confirmed
• Suicidal Ideation and Mood Disorders: Advise patients to seek medical attention for suicidal ideation, suicidal behavior, new onset or worsening depression, anxiety, or other mood changes
• Hepatic Transaminase Elevations: Dose-dependent elevations in serum alanine aminotransferase (ALT). Counsel patients on signs and symptoms of liver injury
• Potential for Reduced Efficacy with Estrogen-Containing Contraceptives: Use non-hormonal contraception during treatment and for one week after discontinuing Elago 200 mg Tablet.

Food Interaction

• Administer calcium supplement. This will minimize the risk of bone mineral density loss.
• Administer vitamin supplements. Administer Vitamin D supplements to minimize the risk of bone mineral density loss.
• Take at the same time every day.
• Take with or without food.

Contraindication

Elago 200 mg Tablet is contraindicated in women:

• Who are pregnant
• Exposure to ORILISSA early in pregnancy may increase the risk of early pregnancy loss.
