TAMOXIFEN ACTION MECHANISM

Tamoxifen (antiestrogen or Selective Estrogen Receptor Modulator (SERM)) acts by competitively binding to estrogen receptors present on tumors and other tissue targets, producing a nuclear complex which decreases synthesis of DNA, thereby inhibiting effects of estrogen. Tamoxifen is cytostatic (prevents (pre)cancerous cells from dividing) and not cytocidal (does not cause cell death).

TAMOXIFEN DOSAGE

Tamoxifen dosage should be taken as exactly prescribed by your health care professional because its dosage depends on severity of condition and medical history. Tamoxifen medication is usually recommended with a full glass of water and can be taken with or without your meals.
