Generic Name: Tamoxifen citrate
Product Name: Tamoxen

Indication

Tamoxifen is used in the palliative treatment of breast cancer that has been shown to express oestrogen receptors.

Action

Tamoxifen is a non-steroidal anti-oestrogen. It probably works by binding to oestrogen receptors, and this inhibits the effects of endogenous oestrogen. Many breast cancers have oestrogen receptors and therefore have their growth stimulated by the presence of oestrogen. By inhibiting oestrogen, Tamoxifen inhibits tumour growth.

Initial dose is 20mg once daily. If no improvement is seen within one month, increase to 40mg daily.

S4
