Cannabidiol (cbd) - Bazedoxifene Acetate, Conjugated Estrogens Interaction

Interaction Details

Bazedoxifene Acetate, Conjugated Estrogens is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates

Cannabidiol might increase levels of drugs that are metabolized by CYP3A4.
In vitro and animal research shows that cannabidiol inhibits CYP3A4. In human studies and case reports, cannabidiol has been associated with an increase in plasma levels of the CYP3A4 substrates zonisamide, tacrolimus, everolimus, citalopram, and methadone.

Interaction Details

Bazedoxifene Acetate, Conjugated Estrogens is classified as belonging to the following category: Glucuronidated Drugs

Cannabidiol might increase levels of certain glucuronidated drugs.
In vitro research shows that cannabidiol inhibits uridine diphosphoglucuronosyl transferase (UGT) 1A9 and UGT2B7, enzymes responsible for glucuronidation. Theoretically, this could decrease the clearance and increase levels of glucuronidated drugs.

Bazedoxifene Acetate, Conjugated Estrogens Overview

• Estrogen and bazedoxifene tablets are used to treat hot flashes (sudden feelings of warmth, especially in the face, neck, and chest) in women who are experiencing menopause (stage of life when menstrual periods become less frequent and stop and women may experience other symptoms and body changes). Estrogen and bazedoxifene tablets are also used to prevent osteoporosis (condition in which the bones become thin and weak and break easily) in women who have undergone menopause. Estrogen is in a class of medications called hormones and bazedoxifene is in a class of medications called estrogen agonist–antagonists. Estrogen works by replacing estrogen that is normally produced by the body. Bazedoxifene is used to block the action of estrogen on the lining of the uterus, decreasing the risk of overgrowth that may lead to cancer.
