Which drug class does Evista belong to?

Evista is classified as an osteoporosis agent, specifically a selective estrogen receptor modulator (SERM). This drug is primarily used to prevent and treat osteoporosis in postmenopausal women by mimicking estrogen's beneficial effects on bone density without some of the risks associated with estrogen therapy. It helps maintain bone strength and decreases the risk of fractures, making it an important option in the management of osteoporosis.

In contrast, other drug classes listed do not pertain to the primary uses or mechanisms of action of Evista. Antihypertensives are used to manage high blood pressure, antioxidants are substances that help prevent cell damage, and antidepressants are used to treat depression. Each of these classes addresses specific health issues that are distinct from the role Evista plays in osteoporotic treatment.
