Class/mechanism: SERM (selective estrogen receptor modulator), with estrogen agonist/antagonist properties depending on tissue type. Tamoxifen has estrogen antagonist properties in breast tissue. It has estrogen agonist properties in bone, helping to decrease bone resorption, but in contrast to Raloxifene (Evista), it also has agonist properties in uterine tissue.[1][2]

Extravasation: n/a
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]

History of changes in FDA indication
- Uncertain date: Approved for the treatment of node-positive breast cancer in postmenopausal women following total mastectomy or segmental mastectomy, axillary dissection, and breast irradiation.
- Uncertain date: Approved for the treatment of metastatic breast cancer in women and men. Available evidence indicates that patients whose tumors are estrogen receptor positive are more likely to benefit from NOLVADEX therapy.
- 3/16/1989: Approved for use in premenopausal women with metastatic breast cancer as an alternative to oophorectomy or ovarian radiation.
- 10/29/1998: Approved to reduce the occurrence of contralateral breast cancer in patients receiving adjuvant Nolvadex therapy for breast cancer.
- 10/29/1998: Approved to reduce the incidence of breast cancer in women at high risk for breast cancer.
