Endoxifen

Endoxifen is an active metabolite of tamoxifen, primarily used in the treatment of hormone receptor-positive breast cancer. It belongs to a class of drugs called selective estrogen receptor modulators (SERMs). Endoxifen is known for its ability to block estrogen’s effects on breast tissue, helping slow or stop the growth of hormone-sensitive tumors.

Uses of Endoxifen

• Treatment of estrogen receptor-positive breast cancer
• Prevention of recurrence in breast cancer patients
• Alternative to tamoxifen in cases of poor metabolism
• May be used in ongoing clinical research for other hormone-driven conditions

How Endoxifen Works

Endoxifen works by binding to estrogen receptors in breast tissue, blocking the effects of estrogen. This reduces the growth and survival of estrogen-dependent cancer cells.

Benefits of Endoxifen

• Effective in hormone-sensitive breast cancer
• Better bioavailability than tamoxifen in certain patients
• May reduce the risk of cancer recurrence
• Alternative for patients with CYP2D6 enzyme deficiency
• Potential for fewer drug interactions compared to tamoxifen
