Q: I am a 50-years-old female. I would like to know the function of a drug with the name of Letrozole. And also the generic names and function of Zyphosis and Zolta.

A:Letrozole acts by inhibiting oestrogen in post-menopausal women, a female hormone. In some cases, the presence of oestrogen stimulates tumour growth; hence by blocking it tumour can be treated. Zolta and Zyphosis do not appear on the international data bank of quality brands.
