Select phytoestrogen pharmaceutical compositions and methods of use for
preventing or reducing one or more symptoms associated with pre
menopause, menopause, and/or post menopause are described herein. These
select phytoestrogen formulations are composed only of two or more
plant-derived estrogenic molecules and/or their structural analogues and
exhibit binding preference to ER.beta. over ER.alpha. and agonist
activity in the brain. These ER.beta.-selective phytoestrogen
formulations cross the blood-brain-barrier and promote
estrogen-associated neurotrophism and neuroprotection mechanisms in the
brain, without activating proliferative mechanisms in the reproductive
tissues and are therefore devoid of other estrogen-associated problematic
aspects. The formulations can be administered enterally, transdermally,
transmucosally, intranasally or parenterally. The formulations preferably
contain combinations of compounds, and can be formulated for daily,
sustained, delayed or weekly/monthly administration. In a preferred
embodiment, these are administered to women who are in menopause or post
menopausal, most preferably early in menopausal.
