Chemically stable compositions of 4-hydroxy tamoxifen and their therapeutical applications

摘要

A class of chemically stable 4-hydroxy tamoxifen compositions is characterized by roughly equal amounts of the Z-4-hydroxy tamoxifen and E -4-hydroxy tamoxifen isomers, such that the potency of the compositions is not affected adversely by the isomerization that occurs between these two forms. The inventive compositions are useful for preventing or for treating medical conditions.
